libcurl (.net) with C# :
I determined that 9 out of 10 times downloading my various pdf files
will work. The problem is the 1 of 10 times where the pdf returned was
22kb (and corrupt) instead of a working pdf of size 40kb...
Please let me know if there is an alternate way I can write my pdf out..
I've spent so much time and I'm at the end of the ropes.. Any help would
be appreciated! Below is the key code areas..
// Code to Download the pdf
try
{
easy.SetOpt(CURLoption.CURLOPT_URL, linkToPDF); //
prep for downloading the PDF
Easy.WriteFunction wfile = new
Easy.WriteFunction(OnWriteFile); //attach method for writing to a file
easy.SetOpt(CURLoption.CURLOPT_WRITEFUNCTION, wfile);
_binaryWriter = new BinaryWriter(File.Open(savePath, FileMode.Append));_
_easy.Perform(); // download PDF_
binaryWriter.Close(); //close file
}
catch (Exception e)
{
return results =
PageParseResults.FileDownloadedOrSavedNotSuccessful;
}
easy.Cleanup();
Curl.GlobalCleanup();
// Writing to File.. (Potential Problem Area)
public Int32 OnWriteFile(Byte[] buf, Int32 size, Int32 nmemb, Object
extraData)
{
binaryWriter.Write(buf, 0, nmemb);
return size * nmemb;
}
