Description:
------------
COM handling in php5-win32-200406101030 is failing where it works without error in 4.3.7.  For CrystalRunTime.Application, it is crashing with the following commands:

$creport->DiscardSavedData;  (in example below)
$creport->ReadRecords();
$creport->Export(false);

Reproduce code:
---------------
$crapp = new COM("CrystalRunTime.Application");
$creport = $crapp->OpenReport("c:\\myweb\\reports\\myreport.rpt", 1);
$creport->DiscardSavedData;


Expected result:
----------------
(no failure expected)

Actual result:
--------------
Fatal error: Uncaught exception 'com_exception' with message 'Error Member not found. ' in C:\myweb\htdocs\printlib.php:3 Stack trace: #0 C:\myweb\htdocs\faxcoverpage.php(26): PrintReport('myreport.rpt', '0', 'myreport', '', 'printmyreport.ph...', 'portrait', '1', Array) #1 {main} thrown in C:\myweb\htdocs\printlib.php on line 3

I have also had this issue.

Win2K Server
Apache 2.0.49
PHP 5.0.0 RC3

$oMapDoc = new COM("Autodesk.MapWindowFile") or die("Unable to instantiate a MapWindowFile object");

($bDATValidate) ? $oMapDoc->ValidateMwx = true : $oMapDoc->ValidateMwx = false;

($bDATCompress) ? $oMapDoc->CompressMlf = true : $oMapDoc->CompressMlf = false;

$oMapDoc->ReadFromMwx($sMWXFilenam);

($sPermMWFFilenam = tempnam( $sOutputdir, "mlf_" )) ? true : die("Unable to generate an output file name");

unlink($sPermMWFFilenam);	//It drops the temp file in place whether you use it or not....

$sPermMWFFilenam = str_replace(".tmp", ".mlf", $sPermMWFFilenam);
					//print($sPermMWFFilenam . " & " . $sGroupname . " & " . $sLayername);
					$oMapDoc->WriteToMlf($sPermMWFFilenam, $sGroupname, $sLayername);  // <------This is the line that fails....

I'm not "me tooing" (I hope).  The COM object in question is the Autodesk MapGuide Dynamic Authoring Toolkit.  The call to instantiate, set a couple of properties and read a file work fine, but the call to create a new file (the WriteToMlf() call) fails with com_exception, source: unknown description: unknown.  Catching the exception yeilds zero usable information.  I tried casting the input values as VT_BSTR, VT_UNKNOWN and VT_VARIANT, but nothing worked.  It should be noted that there is a similar method called WriteToMwf() that takes a single argument, and it works fine.

While I'm at it, there's a method called WriteToMwfStream() that returns a binary array, but I can't get to it.

Let me know and I'll see if I can dig up the idf for this thing.

Please open a separate report for your issue; if you can, please determine the IDL for that COM object.
(this might help: http://www.php.net/com_print_typeinfo)

andy at advancethermal dot com:
$creport->DiscardSavedData(); // method calls have () in PHP

Marking this report as bogus since it contains no usable information about a PHP bug.

as previously stated, this is a bogus report.
