Report.Export raises an exception "The path is not of a legal form" when exporting to stre

Trebor

Hi,

I get the exception "The path is not of a legal form" when I try to export a report to stream. ( Export to file works O.K. )

Here is the code that I'm using:

Report rep = new Report();
rep.Load(Request.PhysicalApplicationPath + "MyRep.frx");
rep.RegisterData(... some data ... );
rep.Prepare();
FastReport.Export.Html.HTMLExport export = new FastReport.Export.Html.HTMLExport();
MemoryStream St = new MemoryStream();
rep.Export(export, St); // this line causus an error

Any help will be appreciated,

Trebor

Hello,

HTML export output can't be saved to a stream because it may contain several files (.html file per each report page + image files).

I changed the HTML export filter with RTF filter, but now I'm facing another error
( "Cannot start process because a file name has not been provided.") when exporting to stream:

Report rep = new Report();
rep.Load(Request.PhysicalApplicationPath + "MyRep.frx");
rep.RegisterData(... some data ... );
rep.Prepare();
FastReport.Export.RichText.RTFExport export = new FastReport.Export.RichText.RTFExport();
MemoryStream St = new MemoryStream();
rep.Export(export, St); // this line causes the error "Cannot start process because a file name has not been provided."

Any help ?

Set export.OpenAfterExport to false. I will fix this later.

Now, the stream length is OK ( the same with the file length when exporting to file ), but the stream content is emtpy .
( When I read the stream content into byte array, the whole array is filled with bytes with value = 0 )

FastReport.Export.RichText.RTFExport export = new FastReport.Export.RichText.RTFExport();
export.OpenAfterExport = false;

MemoryStream St = new MemoryStream();
rep.Export(export, St);

Byte[] buffer = new Byte[St.Length];
St.Read(buffer, 0, (int)St.Length); // all the elements of the buffer are bytes with value = 0


Any help ?

Set St.Position to 0 before read from stream.
