Export into pdf raise an error?

Hai to all,

I'm using Crystal Report 11.5, Asp.net2.0-C#.

I dynamically bind some records to the report document. Now i write the code to export the data into pdf file.


MemoryStream oStream; // using System.IO

oStream = (MemoryStream)



Response.Buffer= true;

Response.ContentType = "application/pdf";



The problem is after the above code reached

i'm getting two errors as

Adobe Reader cannot open CA2V0915.pdf because it is either not a supported file type or because the file has been damaged (for example it was sent as an email attachment and wasnt correctly decoded

Threre was an error openning this document Acrobat cannot open this file because there is a modal dialog open.

Experts please help me solve this problem>

Thanks in advance.

    Try adding a Response.End(); after you do the BinaryWrite.

    • I think the place to start on all of this is with a simple sample app that does not use exportostream. Rather, simply export to pdf from the app. This file;

      contains a number of sample apps. I'd start with vbnet_win_exportopdf and see if you can export from that app. Use a "saved data" report so you do not have to code the database logon.

      vbnet_win_simplepreviewreport may also be a good app. See if exporting from the viewer works.

      All of the above and the whole thread assumes (though the question was not posed) that you can export to pdf from the CR designer(?).

    Generally, this kind of error message appears because by default the PDF file is saved to the temp folder. It could be that the temp folder on your computer is full and cannot accept any more files.

    Try to remove some files from the temp folder and see how it goes.
