Need to Sendmessage to an App

[Oppenhiemer]

Hi all -

Basically,I would like to send a message to Windows Media player to make it go to full screen mode from my app.

The actual key combination to achive this in the App itself is ALT+ENTER. There seems to be more than one approach to achieving this - and I guess Im after the simplest ;-).

I guess I could use SendKeys or Sub-class the apps Winodws procedure and send a message directly (one i know the correct params etc.) The second way (as I remember from grim experience) can be quite complex - so another method would be preferable (SendKeys ?)

Anyway, does anyone know how I can achive this task ?

Many thanks..

I think you could use:

Handle := findwindow(pchar('WMPlayerApp'),pchar('Windows Media Player'));

ShowWindow(Handle,SW_Maximize);

I haven't tried this myself.

Use SendMessage to send the appropriate WM_KEYDOWN messages. Presumably that would work.

Thanks guys - solved it. Dont know why, but I did not get an email notification that anyone answered this thread. Anyway as I say, managed to solve it using both what Brian and mikeEd suggest.

What the customer wanted was to automatically launch Windows Media player when windows started - then go immediately to Full SCreen mode (it was for some sort of running demo.) When I realised that you could not do this with command line arguments, thought I would have to do some programming ;-).

So good result in the end and thanks for feedback.
