Thank you for your response. I would like to mention that I have since solved
this problem by using a feature of Reporting Services so this is not critical
for me any more in terms of getting a solution. However, I am stil curious in
terms of your opinion as to why this didn't work so that similar blockers can
be overcome in the future. Please dedicated your time to this when you have
some to spare.
The code is as follows (as I haven't cleaned up the code, please ignore any
portions that we inserted for debugging purposes). Please note that, in order
to run this successfully, you would need to add a Web reference to the
Reporting Services Web service.
// Create an instance of the proxy class for the Reporting Service
// Web service, and then specify the access credentials.
rsProxy = new MyReport.ReportingService();
rsProxy.Credentials = CredentialCache.DefaultCredentials;
// Prepare arguments for calling WebMethod "Render".
string historyID = null;
string deviceInfo = null;
deviceInfo = "<DeviceInfo><OutputFormat>BMP</OutputFormat></DeviceInfo>";
string showHide = null;
MyReport.ParameterValue[] param = null;
MyReport.DataSourceCredentials[] credentials = null;
Byte[] results;
string encoding; //Encoding used by WebMethod
string mimeType;
MyReport.Warning[] warnings = null; //To collect warnings returned by
WebMethod
MyReport.ParameterValue[] reportHistoryParameters = null;
string[] streamIDs = null;
// Execute the report. In the absence of Reporting Services,
// I think (but I am not sure) that retrieving an image stream
// from an image file will serve for testing purposes.
results = rsProxy.Render("/ESTP Reports/PartnerUpdate", "IMAGE",
historyID, deviceInfo, param,
credentials, showHide, out encoding, out mimeType,
out reportHistoryParameters, out warnings, out streamIDs);
// Copy the stream to the clipboard.
MemoryStream MemStream = new MemoryStream(results);
DataObject d1 = new DataObject();
// I have tried changing the first parameter to the other
// possible options but all fail with some error or the other.
d1.SetData(DataFormats.Bitmap,true,MemStream);
Clipboard.SetDataObject(d1, true);
// PowerPoint automation.
PowerPoint.Presentation ppt;
PowerPoint.Application pptApp;
PowerPoint.Slide slide;
pptApp = new PowerPoint.Application();
ppt = pptApp.Presentations.Add(MsoTriState.msoTriStateMixed);
slide = ppt.Slides.Add(1, PowerPoint.PpSlideLayout.ppLayoutBlank);
// I have tried changing the first parameter to the other
// possible options but all fail with some error or the other.
slide.Shapes.PasteSpecial(PowerPoint.PpPasteDataType.ppPasteBitmap,MsoTriState.msoFalse,"",0,"",MsoTriState.msoFalse);
ppt.SaveAs("D:\\Ata\\test.ppt",
PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, MsoTriState.msoTrue);
Thanks once again for your help!

Ajay.
