Receive Windows Broadcast Messages from a C++ program.

[siujoe]

Hi,

My app is written in vb.net 2003, I need to receive broadcast messages
sent from another application written in VC++6.
It doesn't seem i can import system.messaging, I also tried windows
API RegisterWindowMessage but no luck.
Hope someone can give me some suggestions.
Thanks!!!

"Broadcast Message"?
Does that translate to a Windows Message?
If so, override WndProc in your Form and pick out the relevant Message.

Thanks Phill,

Yes it is Windows Message, I found some examples on vb6, but having problem
translating to vb.net...

how do you convert Addressof funcname to vb.net?

Handling Windows Messages is done totally different in VB.Net.
Pop this into your Form code:

Protected Overrides Sub WndProc(ByRef m As Message)

Const WM_ACTIVATEAPP as Integer = &H1C

Select Case m.Msg
Case WM_ACTIVATEAPP

' Switch from another Application

End Select

' Very, *very* important bit!!
MyBase.WndProc(m)

End Sub
