>How do I call a Visual Basic program from a Visual Basic program with a sending value/parameter. Please help...
Lots of ways. Assuming that the VB program accepts a command line parameter, you can run in using the native RUN command in VFP, or use any of several API calls to fire it with an approrpiate command line (ShellExecute() and CreateProcess() work just fine; there's an example of using CreateProcess() in a recent FAQ entry I wrote on running an external program and waiting on it to complete.) And several automation objects provide mechanisms as well.

I was using a custom AcitveX control to interact with scanners in my VFP program. It works fine but I cannot print the scanned image stored in the ActiveX control. I know that I need to get the unique value defined in Windows for the printer (and in VB it is printer.hDC) There is no where in VFP could I find something similar to hDC in VB.
Take a look at messages posted in the last few days; there was a thread that discussed using a method of an RTF ActiveX control to retrieve the printer handle.
