Visual Basic and Sage: Send Message Help

[Jack_PVR]

I'm trying to use VB 6 to control SAgeTV via SendMessage, just not working, any suggestions?

The popup box returns the correct handle but the message (info) is not sent...

'In a module
Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( ByVal lpClassName As Any, ByVal lpWindowName As Any) As Long


'In the form button click code

Private Sub Command1_Click()
MsgBox FindWindow("SageApp", "SageWin")
Call SendMessage(FindWindow("SageApp", "SageWin"), 1258, 24, 24)
End Sub

I am a C/C++ programmer, so I may have no idea what I'm talking about here. Now that you were forewarned... is lParam being sent correctly? It is declared differently than the other parameters in SendMessage's "Public Declare Function" line.

FYI, instead of sendmessage you can now use command line parameters to do the exact same thing. I assume you are creating your own frontend? If not, would you mind telling us what you are working on? Sorry, just nosy.

Yes, but running "SageTV.exe -event #" is much slower than sending the messgae yourself, or running a much smaller program to do the same thing -- so there is still an advantage to doing it yourself.

Edit: This is true on my slow system; your results may vary.

True Opus4 but I am lazy!

OK then -- go download the recent general purpose SendMessage.exe I uploaded & you won't need to do it yourself.

Thanks guys for the suggestions...

Figured it out, I needed to pass the lParam ByVal.

I would like to use sendmessage to play an mpeg file with a command line or VB6. Does anyone have a short example how a mpeg file could be played with sendmessage?
