IOException with Aspose.Slides.Presentation

Aspose.Slides Product Family
1

Hello

I have a Visual Studio 2005 WinForm project (C#), and have downloaded Aspose.Total. When I execute the code below, I get an IOException for the 2-nth button click on the call to SaveToPdf(). Any ideas on what the problem might be?

Thanks

Mike

Error: The process cannot access the file 'c:\tmp\foo.pdf' because it is being used by another process.

private void button1_Click(object sender, EventArgs e)
{
string sBaseDir = "c:\\tmp\\

string sInputFile = sBaseDir + "foo.ppt";

string sPDFOutputFile = sBaseDir + "foo.pdf";

Presentation pres = new Presentation(sInputFile);

pres.SaveToPdf(sPDFOutputFile);

PdfConverter converter = new PdfConverter();

converter.BindPdf(sPDFOutputFile);

converter.DoConvert();

int imageCount = 1;

while (converter.HasNextImage())
{
converter.GetNextImage(sBaseDir + imageCount + ".tiff", System.Drawing.Imaging.ImageFormat.Tiff);
imageCount++;
}
}

Dear Mike,

Thanks for considering Aspose.Slides.

You should not get this error in latest version of Aspose.Slides 2.8.5.0.

Anyway, modify your line into this

FileStream fout = new FileStream(sPDFOutputFile, FileMode.Create, FileAccess.Write);
pres.SaveToPdf(sPDFOutputFile);
fout.Close();

Further, you don’t need Aspose.PDF to convert slide images into TIFF, you can directly save them in TIFF format.
