 Posted: Mon Feb 11, 2008 10:09 pm Post subject: [C++] Calculating the lParam for WM_SYSKEYDOWN |
 |
|
I've been trying to figure this out for a while, and it's about to drive me insane.
I'm trying to use PostMessage to send WM_SYSKEYDOWN to notepad. I've sent regular messages fine, whatever. However, I can't figure out how to calculate the lParam for WM_SYSKEYDOWN.
[url=http://msdn2.microsoft.com/en-us/library/aa924492.aspx[/url]MSDN[/url ] has this screwed up table, which is confusing the crap out of me. All the Google searches turn up pre-defined lParams, calculated by Spy++ or something..
So could someone please explain to me how you calculate this before I go insane?
I really would prefer not to have that weird ass
| Code: |
(LOWORD)((HIWORD)0x12903875)
|
crap, but if that's the only way, then lay it on me.

| Maybe you'd have better luck sending WM_CHAR first off?

What I'm trying to do is send a key combination like
For example, to get to the File menu of notepad.

It's almost exactly like a WM_KEYDOWN message. In fact... theres barely a difference.
| Code: | | http://msdn2.microsoft.com/en-us/library/ms646286(VS.85).aspx |
[URL]BBCode screws up because of the parentheses. This one has something for each bit. 0-31... remember its right to left.

But I don't get it.
What I do for a WM_KEYDOWN is
| Code: |
lParam = (MapVirtualKey(VK_Whatever, 0) << 16) && 0x00FF0000;
|
I don't understand what it means by the 0-31. Does it mean that I actually have to screw with the different bits in the byte?
