PHP 8.2.0 Released!

# The com class

(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)

## Introduction

The com class allows you to instantiate an OLE compatible COM object and call its methods and access its properties.

## Class synopsis

class com extends variant {
/* Methods */
public __construct(
string $module_name, array|string|null$server_name = null,
int $codepage = CP_ACP, string$typelib = ""
)
}

The returned object is an overloaded object, which means that PHP does not see any fixed methods as it does with regular classes; instead, any property or method accesses are passed through to COM.

PHP will automatically detect methods that accept parameters by reference, and will automatically convert regular PHP variables to a form that can be passed by reference. This means that you can call the method very naturally; you needn't go to any extra effort in your code.

## com examples

Example #1 com example (1)

<?php
// starting word
$word = new com("word.application") or die("Unable to instantiate Word"); echo "Loaded Word, version {$word->Version}\n";

//bring it to front
$word->Visible 1; //open an empty document$word->Documents->Add();

//do some weird stuff
$word->Selection->TypeText("This is a test...");$word->Documents[1]->SaveAs("Useless test.doc");

//closing word
$word->Quit(); //free the object$word null;
?>

Example #2 com example (2)

<?php

$conn = new com("ADODB.Connection") or die("Cannot start ADO");$conn->Open("Provider=SQLOLEDB; Data Source=localhost;
);

$rs$conn->Execute("SELECT * FROM sometable");    // Recordset

$num_columns$rs->Fields->Count();
echo
$num_columns "\n"; for ($i=0$i$num_columns$i++) {$fld[$i] =$rs->Fields($i); }$rowcount 0;
while (!
$rs->EOF) { for ($i=0$i$num_columns$i++) { echo$fld[$i]->value "\t"; } echo "\n";$rowcount++;            // increments rowcount

$rs->MoveNext(); }$rs->Close();
$conn->Close();$rs null;

After one week of trying to understand what was wrong with my PHP communication with MS Word, i finally got it working...
It seems that if you're running IIS, the COM object are invoked with restricted privileges.
If you're having permission problems like not being able to opening or saving a document and you're getting errors like:

- This command is not available because no document is open
or
- Command failed

try this (if you're running IIS):

- Execute "dcomcnfg"
- Open Component Services > Computers > My Computer > DCOM Config
- Search for Microsoft Office Word 97-2003 Document (it will be something like this translated to your language, so take a while and search for it)
- Right-Click on it and open the properties
- Choose "Identity" tab
- Normally this is set to "the launching user". You have to change this to "the interactive user" or a admin user of your choice.
- Apply these new settings and test your COM application. It should work fine now.

I hope I save lots and lots of hours of headaches to some of you :)

Took me a while to figure this out by trial and error:

If your frustrated when getting a com-exception like "Error [0x80004002] ..." (with a message nagging you about an unsupported interface), and you're calling a class method through COM that expects a char as an argument, you should NOT call the method with a single-character string.

The correct way of calling a method like this is to use a VARIANT with a type of VT_UI1.

COM enabled method definition:

public bool DoSomething(char arg);

<?php

$com = new COM('Some.Class.Name'); // This will fail$var = 'a';
$com->DoSomething($var);

// This works correctly
$var = new VARIANT(ord('a'), VT_UI1);$com->DoSomething($var); ?> I hope this helps some people yinon at xacct dot com 20 years ago In order to get the Word exaple running, do the following on the server side. Worked for me... 1. Click START-->RUN and enter "dcomcnfg" 2. In the "Applications" tab, go down to "Microsoft Word Document" 3. Click PROPERTIES button 4. Go to the "Security" Tab 5. Click "Use custom access permissions", and then click EDIT 6. Click ADD and then click SHOW USERS 7. Highlight the IIS anonymous user account (usually IUSR_<machinename>), click ADD 8. Go back to the "Security" tab by hitting OK 9. Click "Use custom launch permissions", and the click EDIT 10. Click ADD and then click SHOW USERS 11. Highlight the IIS anonymous user account (usually IUSR_<machinename>), click ADD 12. Hit OK, and then hit APPLY. Also, you should look at the "Identity" tab in the Microsoft Word Document PROPERTIES and see that it is set to "Interactive User" ALSO, log into the machine AS the IUSR_<machinename> account, start word, and make sure to click through the dialog boxes that Word shows the first time it is run for a certain user. In other words, make sure Word opens cleanly for the IUSR_ user. More useful information could be found here: http://www.email-screen.com/support-doc2txt.html mbirth at webwriters dot de 14 years ago Using the DynamicWrapper from http://freenet-homepage.de/gborn/WSHBazaar/WSHDynaCall.htm and after registering it via "regsvr32 dynwrap.dll", you can easily set output colors to make colorful CLI scripts even on Windows. <?php$dw
= new COM('DynamicWrapper');  // needs dynwrap.dll (regsvr32 dynwrap.dll)

// register needed features
$dw->Register('kernel32.dll', 'GetStdHandle', 'i=h', 'f=s', 'r=l');$dw->Register('kernel32.dll', 'SetConsoleTextAttribute', 'i=hl', 'f=s', 'r=t');
$dw->Register('kernel32.dll', 'SetConsoleTitle', 'i=s', 'f=s', 'r=l'); // get console handle$ch = self::$dw->GetStdHandle(-11); // -11 = STD_OUTPUT_HANDLE ?> After these initialization steps, you can set the console output color using: <?php$dw
->SetConsoleTextAttribute($ch, 14); echo 'This is yellow text!';$dw->SetConsoleTextAttribute($ch, 7); echo 'Back to normal gray!'; ?> Using SetConsoleTitle you can even set the title displayed in the console window. Color values are 0..7 for dark colors and 8..15 for light colors. Sequence is (black/silver, blue, green, cyan, red, magenta, yellow/brown, white/gray). I also found that if you add 16384 to the value, it should be inverse. 32768 added should get underlined text. But these latter two didn't work for me. paul at completewebservices dot com dot au 16 years ago It seems that PHP does not support setting of properties with arguments. This is how I got around the problem: // Object with method I want to set$auth = new COM("AUTHXOCX.AuthXOCXCtrl.1");

// ScriptControl
$oScript = new COM("MSScriptControl.ScriptControl");$oScript->Language = "VBScript";
$oScript->AllowUI = TRUE; // Add out object to the control$oScript->AddObject('auth', $auth, true); // Create a VBScript function that allow me to set them$oScript->AddCode(
'Function fixAccess(accessname)
auth.AuthDataReferrerEnabled(accessname) = 1
auth.AuthDataAuthentiXDBEnabled(accessname) = 0
End Function');

// Execute function
$oScript->Run("fixAccess",$dir);

Thanks to paul at completewebservices who added a note earlier; I have used his code to solve a particularly difficult issue with the Crystal 9 runtime component. For some reason, VBA/VBS can pass a native Date type as a parameter to a Crystal Report requiring a date, but in PHP I've tried all manner of strings, unix timestamps, COM variant dates etc and all of these resulted in a com_exception.

My solution was to employ VBScript to borrow the CDate function, which works correctly. Not the most elegant of solutions, but this parameterised approach is to be preferred to search-n-replacing the RecordSelectionFormula string. Of course if anyone here has an even better approach, do post it here - I am sure it would be of use.

<?php
// $rptParam is a report parameter object having a type of date$oScript = new COM("MSScriptControl.ScriptControl");
$oScript->Language = "VBScript";$oScript->AllowUI = false;
$oScript->AddObject('rptParam',$rptParam, true);
$oScript->AddCode('Function SetDateParameter(strDate) rptParam.AddCurrentValue(CDate(strDate)) End Function' );$oScript->Run("SetDateParameter", "25 April 2006");

If you're using COM to create a DSN Less connection to an MS Access 2007 database, you'll find through Googling that you need to use an updated version of Jet, so the connection string I've found looks like this:

<?php
$databaselocation = "C:\Path\to\db.accdb";$conn = new COM('ADODB.Connection') or exit('Cannot start ADO.');
$conn->Open("Provider=Microsoft.ACE.OLEDB.12.0; Data Source=$databaselocation") or die('Cannot start with Jet');
?>

However, on my setup (WinVista, Access 2007, PHP526) I found that it always 'dies' with "Cannot start with Jet", even if the connection was successful ($conn->State reads "1"). I figured to just drop the die() command on$conn->Open(). If something catastrophic happens with the ADO connection then it's own error handling engine passes stack traces, etc back to the console/standard output.

Therefore, my Open() command looks like this:

<?php
$conn ->Open("Provider=Microsoft.ACE.OLEDB.12.0; Data Source=$databaselocation");
?>

Getting IE to the foreground
If you are using a command line (CLI) version of PHP on a Win32 platform (e.g. XP Pro, SP2), you might want to have output directed to IE (perhaps you'll want to work with the output there) when Popup does not suffice (see my earlier post, below).

It's easy enough to get an instance of IE using $ie = new COM("InternetExplorer.Application");. The problem is, you don't necessarily see it in the foreground (especially if you already have one open) and who wants to waste keystrokes getting to it? The code below has been working for me (If you want to do other adjustments (e.g.$ie->Document->ParentWindow->resizeTo(800,500); or $ie->Document->Body->bgColor = "yellow";), doing them before the$ie->Visible = true; line will avoid screen distractions):

<?php
function newIEtoForeground($title,$evtPrefix="") {

// brings new instance of IE to foreground with title $title if (!$extPrefix) $ie = new COM("InternetExplorer.Application"); else$ie = new COM("InternetExplorer.Application", $evtPrefix);$ie->Navigate2("about:blank");

$oWSH = new COM("WScript.Shell"); while ($ie->ReadyState!=4) usleep(10000);

$ie->Document->Title = ($tmpTitle = mt_rand());  //unique title

$ie->Visible = true; while (!$oWSH->AppActivate("$tmpTitle - M")) usleep(10000);$ie->Document->Title = $title;$ie->Document->ParentWindow->opener="me"// allows self.close()

return $ie; } ?> Csaba Gabor from Vienna z3n at overflow dot biz 13 years ago On a query reply using ADODB.Connection object, all my$rs->Fields['field_name']->Value returned variable Object when inserted into a array, like this:

<?php
for ($rl[$v]=array(),_qm($_query);!$res->EOF;$res->MoveNext()) {$rl[$v][]=$res->Fields['x']->Value;
}
?>

I figured out that converting the value into a INT fixed the issue:

<?php $rl[$v][]=intval($res->Fields['x']->Value); ?> rickardsjoquist at hotmail dot com 19 years ago If you want to use a DSN-less connection to a database (access for example) and return the results of a query as a multidimensional array with the fieldnames as identifier try this.

Hi, just wanna share to everyone after tried and tested many many times to create report in PDF format from Crystal Report.
Finally I can do it without any error.
Here is my system; PHP 5.1.6, MSSQL2005 and Crystal Report Server XI RL2

<?php

//-Create new COM object-depends on your Crystal Report version
$ObjectFactory= new COM("CrystalReports115.ObjectFactory.1") or die ("Error on load"); // call COM port$crapp = $ObjectFactory-> CreateObject("CrystalDesignRunTime.Application"); // create an instance for Crystal$creport = $crapp->OpenReport($my_report, 1); // call rpt report

// to refresh data before

//- Set database logon info - must have
$creport->Database->Tables(1)->SetLogOnInfo("servername", "DBname", "user", "password"); //- field prompt or else report will hang - to get through$creport->EnableParameterPrompting = 0;

$creport->DiscardSavedData;$creport->ReadRecords();

//export to PDF process
$creport->ExportOptions->DiskFileName=$my_pdf; //export to pdf
$creport->ExportOptions->PDFExportAllPages=true;$creport->ExportOptions->DestinationType=1; // export to file

$creport = null;$crapp = null;
$ObjectFactory = null; //------ Embed the report in the webpage ------ print "<embed src=\"D:\\Folder1\\SubFolder1\\Report.pdf\" width=\"100%\" height=\"100%\">" ?> That's all for me, anyway in Crystal Report I have to check DisCardSavedData, Save data with report and AutoSave (1 min) in Option Tab and also in Report Options I have to check save dat with report, too. Hope this should be help to anybody Casanoteva csaba at alum dot mit dot edu 17 years ago Basic Windows IO If you are using a command line (CLI) version of PHP on a Win32 platform, you might like to have a simple graphical interface to get input and output. The following gives an illustration for both. <?php // first we get some input$oScript = new COM("MSScriptControl.ScriptControl");

$oScript->Language = "VBScript";$title = "I/O Demo: Input half";

$initial = "Change this value";$prompt = "Please enter a value";

$code = <<<EOF Function getInput() inVal = InputBox("$prompt", "$title", "$initial")
getInput = inVal         'how return values are assigned in VB
End Function
EOF;

$oScript->AddCode($code);

$input =$oScript->Eval("getInput()");
if (
gettype($input)=="NULL")$input = "Input box was cancelled";

// now we show some output

$oWSH = new COM("WScript.Shell");$title = "I/O Demo: Output half";

$timeout = 2; // 0 for no timeout$style = 0 + 48;    // buttons to show + alert symbol

$oWSH->Popup($input, $timeout,$title, $style); ?> This is example is overblown for illustrative purposes. The whole input part collapses if the amount of code used is a single statement. So, this would have sufficed:$code = "InputBox(\"$prompt\", \"$title\", \"$initial\")";$input = $oScript->Eval($code);

This technique exposes quite a bit of scripting power tied into the Windows operating system and VBScript.  However, you should have a really specific reason for using it since VBScript tends to be dog slow when compared to PHP in my tests.  Simple IO like this is good, however, and the popup size can be quite large.  Furthermore, this could be a viable route to go for accessing WinAPI's.

<?php $var = new COM('Whatever.Something') or die(); ?> however the 'or die()' bit is redundant as a fatal 'com_exception' exception will be thrown, killing your script. If you want to handle the 'or' condition you need to catch the exception, eg <?php try {$var = new COM('Whatever.Something');

If you can get the old "TaskScheduler.dll" and register it, it is quite simple to handle and start Windows tasks from PHP.
This is extremely useful when you got things to do which must be run in a different user context. Prepare a task with the user and use PHP & Com to build a webinterface for it.

Here is an example how to start a Windows task:

function start_task ($taskname) {$SchedObj = new COM("Scheduler.SchedulingAgent.1");
foreach ($SchedObj->Tasks as$task) {
if (strtolower( (string) $task) == strtolower($taskname.".job" )) {
$task->Run(); } } } I'm also working on a class to handle infos, adding and removing of tasks via PHP. If you are interested drop me a line. phpguy _from_ toshpro _dot_ com 18 years ago if you ever need to connect to an access database (on the server, using the IIS or APACHE user account), here is code below that can help to ease the process. It is written like this because we have a MySQL as well as an Access database and need to be able to switch back and forth. The runQuery function will return a 2 dimensional array and can use column names or numbers for the index of the internal arrays. External arrays are always integer-indexed. We also have found issues with Access staying open and growing from 7MB to 2.5GB within two hours, so we open and close it each time we run a query. If it is not a select query it will return TRUE. if it fails with errors, it will return false. There is a showErr flag that we mostly only use for MySQL, since you can output MySQL errors without PHP errors. Access doesn't appear to be that friendly. <?php function runQuery(&$conn,

$strSQL,$associative=true,

$debug=false,$showSQL=false,

$showErr=false) { return runMSQuery($conn,$strSQL,$associative,$debug,$showSQL,$showErr); //return runMyQuery($conn,$strSQL,$associative,$debug,$showSQL,$showErr); } function openMSDB($dbfile="c:/path/and/filename.mdb") {

The examples backup the IIS MetaBase (your server's website(s) configuration) in IIS. VBScript: Dim obj, iFlags Set obj = GetObject("IIS://LocalHost") ' Backup to next available version number. ' Set flags to save the metabase first and ' force the backup even if save fails. iFlags = (MD_BACKUP_SAVE_FIRST or MD_BACKUP_FORCE_BACKUP) obj.Backup "MyBackups", MD_BACKUP_NEXT_VERSION, iFlags ' Note: The above was copied from Microbucks. ' This is how you would have to do it. ' i.e. use the actual constant's value. iFlags = (2 or 4) obj.Backup "MyBackups", &HFFFFFFFF, iFlags PHP: <?php$obj

My previous notes about Crystal Reports have vanished away, but anyway I was up to correct them.

The code above connects to COM (beware of the version number! search on the Registry Editor for the correct name to put in $COM_Object), opens a report from a file ($my_report), reload records from database and then exports it to a PDF file ($my_pdf). * IMPORTANT * this code, when invoked from the browser (I'm using Apache) AND with a report that connects to a ODBC database, does not work (the problem is specificly the line ReadRecords(), but may arise without it too when data is not saved into the report file). But when you run this code by PHP-CLI (that is, by the command line), it works ok! I bug-reported this, but have no answer till now ( give it a vote, if you thing it's important: http://bugs.php.net/bug.php?id=36959 ). Also, exceptions may arise, so put it on a try_catch block. -------------------------- // by dfcp '06 (djogopatrao@gmail.com)$COM_Object = "CrystalReports11.ObjectFactory.1";
$my_report = "C:\\report.rpt";$my_pdf = "C:\\report.pdf";

$ObjectFactory= New COM($COM_Object);
$crapp =$ObjectFactory->CreateObject("CrystalDesignRunTime.Application");
$creport =$crapp->OpenReport($my_report, 1);$creport->ReadRecords(); // attention!

$creport->ExportOptions->DiskFileName=$my_pdf;
$creport->ExportOptions->PDFExportAllPages=true;$creport->ExportOptions->DestinationType=1; // Export to File
$creport->ExportOptions->FormatType=31; // Type: PDF$creport->Export(false);

I couldn't find an example anywhere on what I was trying to do.  After taking bits from everyone I ended up with something that worked.

Im using Crystal Reports 10, MS SQL Server 2005, Apache2, and PHP5.

My report uses an SQL Store Procedure and passes some parameter to get the report data, so our PHP must set the database logon info and pass the parameters.

Below is the solution I came up with:

<?php

//------  Variables ------
$my_report = "C:\\Apache2\htdocs\\test\\MyReport.rpt"//This must be the full path to the file$my_pdf = "C:\\Apache2\htdocs\\test\\MyReport.pdf";

//------ Create a new COM Object of Crytal Reports 10 ------
$ObjectFactory= new COM("CrystalReports10.ObjectFactory.1"); //------ Create a instance of library Application -------$crapp = $ObjectFactory->CreateObject("CrystalDesignRunTime.Application.10"); //------ Open your rpt file ------$creport = $crapp->OpenReport($my_report, 1);

//------ Set database logon info ------
$creport->Database->Tables(1)->SetLogOnInfo("MYSERVER", "Database", "user", "password"); //------ Suppress the Parameter field prompt or else report will hang ------$creport->EnableParameterPrompting = 0;

$creport->DiscardSavedData;$creport->ReadRecords();

//------ Pass formula fields --------
$creport->FormulaFields->Item(1)->Text = ("'My Report Title'");$creport->ParameterFields(1)->AddCurrentValue ("FirstParameter");
$creport->ParameterFields(2)->AddCurrentValue (2000); //------ Export to PDF -------$creport->ExportOptions->DiskFileName=$my_pdf;$creport->ExportOptions->FormatType=31;
$creport->ExportOptions->DestinationType=1;$creport->Export(false);

//------ Release the variables ------
$creport = null;$crapp = null;
$ObjectFactory = null; //------ Embed the report in the webpage ------ print "<embed src=\"MyReport.pdf\" width=\"100%\" height=\"100%\">" ?> Obviously there's plenty of room for refinement in there, but it works and should get you going on the right track. I also found that during testing, the script was hanging before supressing the parameter prompt. Once this had happened, some exports that had been working earlier stopped completely and wouldn't work again untill I restarted Apache. This might be something worth doing if you keep having issues after a script has hung. IceNV 5 years ago Under PHP7(.x) 64-bit, there is a documentation error (on the MSDN side, already reported) causing problems if you try to manipulate the registry (StdRegProv) through COM. Indeed, MSDN reports that the registry hive/root must be reported as a uint32, which means that, in PHP 64-bit, one would create a new Variant($root,VT_UI4).

This would throw a type mismatch error.
It seems internally and contrary to what MSDN says (as of now, 2016-12-13), the root parameter must actually be passed as an int32.

So you have to :
1. convert your root number to a negative int to avoid out-of-bounds exceptions when creating the variant below (basically the integer being >= 2^31, you have to wrap it around the 32-bit signed integer maximum yourself) ;
2. create a new Variant($root,VT_I4) ; 3. pass that Variant to your COM API call. This did not happen before PHP 7.0 as it always used VT_I4 internally before (see https://bugs.php.net/bug.php?id=73605), but now it respects (and is right to do so) the real integer length, so without an explicit conversion, PHP7 would now output a VT_I8 on x64, versus VT_I4 for PHP5. Danil_lll 4 years ago Hello. There is a code c# which works with the COM-library (written on C++) - hybrid.dll. I need to rewrite this code from C# to PHP (that is connect the COM-library to the PHP code) Here is the function that is called inside C#: Gr = HybridLib.Hybrid_Color.GREEN; And here is the list of "Hybrid_Color"which in the library: enum Hybrid_Color { GREEN = 0x00000001, BLACK = 0x00000002, BLUE = 0x00000004, }; The library itself was launched in PHP:$PHP_Lib = new COM("HybridLib.Hybrid");

Can not assign value:
$gr =$PHP_Lib -> ..... ?????

What I write next, I don't know...

Changing Fields (Not FORMFIELDS) In MS Word....

Searched most of the afternoon for this, as it is something needed here for our projects.  Maybe this can help someone else as well.

<?php
$input = "x:\\path\\to\\test.doc";$word = @new COM("word.application") or die("Unable to instantiate Word");
print
"Loaded Word, version {$word->Version}\n<br>";$word->Visible = 1;
print
"Set Word To Visible<br>";
$word->Documents->Open($input);
print
"Opened $input<br>";$word->Activate;
print
"Activated Word<br>";

print
"Editing Fields<br>";
$Field =$word->ActiveDocument->Fields(1);
$fieldData =$Field->Result;
$fieldData->Text = "Testing"; // Print the document.$word->Printout();

// closing word
$word->Quit(); // free the object$word->Release();
$word = null; ?> -1 sodeh at dana dot ir 18 years ago for connection to sql server and know the utf-8 code use this method to connect the database$db = new COM("ADODB.Connection",NULL, 65001 );

If your PHP is configured as ISAPI module then the COM object you create in ur php page will use the same memory space as the web server. If your COM object takes too much memory then this may force some COM error as PHP does not handle the memory usage of COM itself. And also Web server doesnt know what do to free COM memory. But if you use PHP as CGI then PHP itself handle the memory usage of COM. Once in a script where i used COM and PHP as ISAPI module i got unknown COM error.But when i used PHP as CGI there was no error. So those who want to use COM object in your application please be careful about it.

Here's a simple example of printing formatted templates with MS Word.

To begin with, I've already built my invoice in Word and saved it as an RTF file.
In this case, I'm using "sampleInvoice.php"

Fields that will be replaced have been marked as ||CUSTOMER ID|| and so on.

<?php
$dataText = ""; // open the file if(!($fp= fopen ("C:\wordTest\sampleInvoice.rtf", "r"))) die ("Can't open");
$dataText = fread($fp, 2000000);
fclose ($fp); // replace the template fields$dataText = str_replace ("||CUSTOMER ID||",$customerIDValue,$dataText);

// save the file as an rtf
$timeStamp = time();$saveFile = "C:/wordTemp/".$timeStamp."-invoice-".$customerIDValue.".rtf";
if(!(
$fq= fopen ($saveFile, "w+"))) die ("Can't open");
fwrite ($fq,$dataText);
fclose ($fq); // initialize the word components$word = new COM("word.application") or die("Unable to instantiate Word");

print
"Loaded word version ($word->Version)\n";$word->visible = true;
$word->Documents->Add(); // open the file$word->Documents->Open("$saveFile"); // output the file to the default printer$word->ActiveDocument->PrintOut(1);

// shutdown word
$word->Quit(); ?> -1 info at sharedprojects dot nl 19 years ago <?php // An other way to connect // this connect to a ODBC-datasourced added in the // ODBC Data Source Administrator under System DSN$odbcname = "northwind";

The example above (MS Word) is quiet unsatisfying, as I find. Especially since I couldn't find anybody who actually got it running, including myself.

You might therefore give this Powerpoint-example a chance:
----------------------------------
#Instantiate a PowerPoint object.
$ppoint = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint"); <?php #Create a new presentation$ppoint->Presentations->Add() or die ("Could not create presentation");

$slide=$ppoint->Presentations[1]->Slides->Add(1,1);

//Get the name of this slide
$slidename =$slide->Name();
echo
"<br>slidename : $slidename"; //Change the name of this new slide$slide->Name = "New Slidename";
$slidename =$slide->Name();
echo
"<br>NEW slidename : $slidename"; //Save the presentation$ppoint->Presentations[1]->SaveAs("c:/InetPub/www/test.ppt");
$ppoint->Presentations[1]->Close(); //closing powerpoint$ppoint->Quit();

//free the object
$ppoint->Release();$ppoint = null;
-----------------------
?>

the config is :
w2k-server/office2k/iis5/php 4.1.1 isapi

If you happen to run into a working word2k-example, please let me know.
