I use the print class of FotoVision to make a image print program, why doesn't it work?
The following code is from FotoVision, I make a image print program using the class,
but it doesn't work. Only after I have installed the FotoVision (The name of setup program is " FotoVision Desktop.msi ")
my program just work. I think that FotoVision have packaged some other components such as dll or registered photowiz.dll in its setup program, but I'm not sure.
If so, how can I register photowiz.dll with C# ? Could you help me, thanks!
// Uses the XP Photo Printing Wizard to print one or more photos.
// The implementation of the photo wizard is in photowiz.dll but the
// interface is not exposed. Instead, Microsoft provides the Windows
// Image Acquisition Library (WIA).

// Use late binding incase the user does not have the WIA component

// not installed).
// use late binding for this source file
