Question

I cannot convert PPT to XPS or PNG to PDF file.

Two ways for this problem is:

First Way: Using COM Component Microsoft. For Example

:Microsoft.Office.Interop.PowerPoint,Microsoft.Office.Core , … .

My Code :

private static void PPT2XPS()
{
    Microsoft.Office.Interop.PowerPoint.Application powerpoint;
    Microsoft.Office.Interop.PowerPoint.Presentation presentation;
    Microsoft.Office.Interop.PowerPoint.Presentations presentations;
    powerpoint = new Microsoft.Office.Interop.PowerPoint.Application();
    presentations = powerpoint.Presentations;
    presentation = presentations.Open(@"d:\test.ppt", MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
    Microsoft.Office.Interop.PowerPoint.Slides slides = presentation.Slides;
    for (int i = 1; i <= slides.Count; i++)
    {
        Microsoft.Office.Interop.PowerPoint.Slide slide = slides[i];
        String slideName = slide.Name;
        releaseCOM(slide);
        slide.Export(@"d:\test\" + i.ToString() + ".xps", "");
    }
}

private static void releaseCOM(object o)
{
    try
    {
        System.Runtime.InteropServices.Marshal.FinalReleaseComObject(o);
    }
    catch { }
    finally
    {
        o = null;
    }
}

Second Way: Sending file to

“Microsoft XPS Document Writer” printer With Process.

My Code :

 Process P = new Process();
    ProcessStartInfo psInfo = new ProcessStartInfo();

    psInfo.FileName = @"C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe";
    string option = @"/t";
    string xps = "Microsoft XPS Document Writer";
    string targetFile = Path.GetDirectoryName(filename) + Path.DirectorySeparatorChar +
        Path.GetFileNameWithoutExtension(filename) +  @".xps";

    string Myargs = String.Format("{0} \"{1}\" \"{2}\" {0} \"{3}\"", option, filename, xps, targetFile);
    psInfo.CreateNoWindow = true;
    psInfo.Arguments = Myargs;
    psInfo.UseShellExecute = false;
    psInfo.ErrorDialog = false;

    P.StartInfo = psInfo;
    P.Start();
    P.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

Third Way: Using API Windows And Sending Binary File .
This is sample for this way :

My Problem :

First Way: COM object that has been separated from its underlying RCW cannot be used

Second Way: Cannot Hidden Window and Close Window

Third Way: Cannot Create XPS File . di.OutPutFile Create ill [bad?] file.
