CreateObject alike for WIA

Hi,

This is a code-snippet from a VB.NET print module

Dim dialog As Object = CreateObject("WIA.CommonDialog")
dialog.ShowPhotoPrintingWizard(vector)

I've tried this in C# as follows:
Type t = Type.GetTypeFromProgID("WIA.CommonDialog");
object dialog=Activator.CreateInstance(t);

But then I cannot access dialog.ShowPhotoPrintingWizard();

I've referenced the waauit.dll now and add using WIA at top.
But still I want to get the other way(without referencing WIA).

Hi kGenius,
----------

you could try
object dialog = CreateObject("WIA.CommonDialog");
dialog.ShowPhotoPrintingWizard(vector);

Is it possible to add a reference, and use early-binding, instead of the late-bound Activator call?

It is possible in my app. I've done it that way (add the reference)
But I was so curious how C# could handle this one.

Thanks bruintje for sharing...

tmp is like this..: "c:/users/me/pictures/abc.jpg"...

What the compiler says is "argument can not be converted from string to "ref object"
If've refered to http://msdn.microsoft.com/en-us/library/ms630492(VS.85).aspx
where is said that also could used a path to afile....

WIA.CommonDialog myprintDialog = new WIA.CommonDialogClass();
String tmp = theBasisPfad + currentDateiname;
theDruckListe.SetFromString(tmp,false,true);
myprintDialog.ShowPhotoPrintingWizard( tmp );
