re: You can't use the WM_USER message in a dialog box
@Joshua: I'm not sure I see the problem. Your dialog box living in a DLL does not change the fact that you own it and hence you define the semantics of all WM_APP range messages that are sent to it....

re: You can't use the WM_USER message in a dialog box
I'm pretty sure that WM_APP was intended for application-wide broadcast and for subclassing DLL-based windows. [WM_APP is for the code that called CreateWindow. Of course, that code can in turn grant...

re: You can't use the WM_USER message in a dialog box
I've also seen WM_USER+100 used as a base in various places (and I plead guilty to using it a few times of my own). Also, about the .Net Framework part: That one registered message will be shared by...

re: You can't use the WM_USER message in a dialog box
Sadly, I've programmed for Windows since 3.0. And it was only last year that I realized that WM_USER wasn't for "the code that called createwindow". Hindsight 20/20 - perhaps WM_USER should have been...

@MattT: I, too, have taken up that behavior of copying my comments before posting. The blog software will silently drop your comment if you don't post it within a certain amount of time.

In terms of this blog site working: works for me. Just requires patience to wait for Raymond to vet each post. :)

"But I called LoadKeyboardLayout last week and it gave me 0x04090409, so the parameter is a locale identifier that was previously returned by LoadKeyboardLayout."

I generally assume that any handle-like data type with an H prefix in its name is not something you can synthesize out of thin air, since there is some important corresponding data hidden away...

re: You can't use the WM_USER message in a dialog box
@MattT: From my experience, comments only "stick" if you post them quickly after loading the post. So you have to write the comment, copy it to the clipboard, reload the post, and then paste and submit...

@Joshue: Yes, that would be an exception. It's well-documented where HKEY_LOCAL_MACHINE comes from and that it's safe to use, unlike (HKL)0x04090409. Note that I said "data type" (as in HANDLE, HKEY,...

I don't know if this is related, but one thing that drives me nuts is programs that add new keyboard layouts without consulting me. Steam and Valve games are extremely guilty of this. I usually only...

re: You can't use the WM_USER message in a dialog box
@ChrisR: For dialog box in a DLL, one approach that we've used is to have the caller supply a window message (or a range of window messages) in the WM_APP space for the dialog box to use.

While we're on the topic of static H values, I know why programs keep being written that think InvalidateRect(NULL, ...) refreshes the desktop. HWND_DESKTOP is defined as 0. Yes I know it's only for...
