I am attaching the code to export all the slides from a Power Point to Images

string ExportLocation = "C:\\Sample";
Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
ppApp.Visible = MsoTriState.msoTrue;
ppApp.WindowState = PpWindowState.ppWindowMinimized;
Microsoft.Office.Interop.PowerPoint.Presentations oPresSet = ppApp.Presentations;
Microsoft.Office.Interop.PowerPoint._Presentation oPres = oPresSet.Open("C:\\ScreenShots.ppt",
            MsoTriState.msoFalse, MsoTriState.msoFalse,
            MsoTriState.msoFalse);
ppApp.ShowWindowsInTaskbar = MsoTriState.msoFalse;	//Hiding the application; But it will be displayed always
try
{
    Slides objSlides = oPres.Slides;	//Getting all the slides
    for (int i = 1; i < objSlides.Count - 1; i++)
    {
        string file = Path.Combine(ExportLocation, string.Format("{0}.{1}", objSlides[i].Name, "jpg"));
        oPres.Slides[i].Export(file, "jpg", 800, 600);
    }
}
finally
{
    ppApp.Quit();	//Closing the Powerpoint application. Sometimes it won't work too.
}

Thanks to ArunKumar, for providing the code snippet.

Command line output from MakeCab/?


MAKECAB [/V[n]] [/D var=value ...] [/L dir] source [destination]
MAKECAB [/V[n]] [/D var=value ...] /F directive_file [...]
source  - File to compress.
destination  - File name to give compressed file. If omitted, the
last character of the source file name is replaced
with an underscore (_) and used as the destination.
/F directives - A file with MakeCAB directives (may be repeated).
/D var=value - Defines variable with specified value.
/L dir - Location to place destination (default is current directory).
/V[n] - Verbosity level (1..3)

But I was unable to create the cab file with multiple files using this. After a long search I found one solution from MSDN – Using MakeCab.exe. Then I have created one .ddf file and using the command


makecab.exe /f Sample.ddf


And in the sample.ddf you can specify the file names.


;*** Sample Source Code MakeCAB Directive file example
;
.OPTION EXPLICIT ; Generate errors
.Set CabinetNameTemplate="Sample.cab"
.set DiskDirectoryTemplate=CDROM ; All cabinets go in a single directory
.Set CompressionType=MSZIP;** All files are compressed in cabinet files
.Set UniqueFiles="OFF"
.Set Cabinet=on
.Set DiskDirectory1="Cabs"

I think the code is self explanatory.

InfoApp.XDocuments(0).PrintOut()

The printout method doesn’t have any parameters like Printer name or port etc. As a workaround you can export the Infopath document as Word, and print the document using Word API, where you can specify the printer name. To export the Infopath as Word there is no direct method, but you can do export to “MHT”(MHTML Document), and change the extention to “.doc” and using Word.Application you can open it and Print.

'Creating the Infopath application
Dim InfoApp As New InfoPath.Application()
'Opening the Infopath document.
InfoApp.XDocuments.Open("C:\Sample\template.xml")
'Exporting the document as Word(MHT)
InfoApp.XDocuments(0).View.Export("C:\Sample\Samplex.doc", "MHT")

Let me know if you find any other solutions

Here is the code to call word macros from VB.Net.

Dim WordApp As New Microsoft.Office.Interop.Word.Application
CType(WordApp, Object).GetType().InvokeMember("Run", Reflection.BindingFlags.Default Or Reflection.BindingFlags.InvokeMethod, Nothing, CType(WordApp, Object), New Object() {"helloworld"})

In the code, helloworld is the macro name.Or you can simply call WordApp.Run("helloworld") will also works fine.
