File doesn't start with %PDF-

I'm having a problem with fpdf files. My page creates a PFD file but in some cases it gives the following error:

error message

Sorry it's in dutch but that's how it works when you work with clients. Anyways it says "File doesn't start with %PDF-. Local\EWH-5128-2

The funny thing is that it does work if I work on the site in localhost. Could this be a server setting?

Hope you guys can help! Thanks in advance!

Solution

  • Solution was as followed:

    In my fpdf.asp a temporary PDF-file was created and then deleted before the program could read it.

                xfile=Server.MapPath(lib.fso.GetTempName())
            xf=lib.fopen(xfile,"wb");
            if(xf.number)this.Error("Unable to create output file: " + xfile);
            lib.fwrite(xf,this.buffer);
            lib.fclose(xf);
            outB = Server.CreateObject("ADODB.Stream")
            outB.Type = 1
            outB.Open()
            outB.LoadFromFile (xfile)
            Response.BinaryWrite(outB.Read())
            outB.Close()
     //       lib.fso.DeleteFile(xfile);

    The problem was solved by deleting the line: lib.fso.DeleteFile(xfile);
