You could actually make it work this way. You use the RegisterWindowMessage Function[^] to create a unique window message and broadcast it using HWND_BROADCAST[^]. Just make sure that your window message is unique and its not in the WM_USER range so it will not conflict with custom window messages used internally in other applications. RegisterWindowMessage will return something in the range of MAXINTATOM-MAXWORD so you should be safe.
In your DLL you could handle this custom message and set the local variable to a target window handle. And since you have both WPARAM and LPARAM this means you could target both PID and window handle. Essentially instructing the DLL "Process with PID x please monitor window n".
This is a sort of hackish way of doing it in my opinion, the shared-data segment in my earlier post would probably be a better choice. You could instruct each DLL there also using a similar technique. The great thing about engineering software is there is always many paths to reach the goal.

Wow! Thank you for sharing all this valuable information to me. Now back on Visual C++ :p

Yes. Think of it this way... your DLL is being mapped into multiple applications each of which is executing inside its own Virtual Address Space[^]. This essentially means that each copy of the DLL has a different value for your global variable named hWindow.
You need to implement a shared data section:
How To Share Data Between Different Mappings of a DLL[^]
This will allow all applications to read from the shared data section.

Well it seems like this shared memory is the solution. I'm going to try it. Thank you!

Hi,
In FAT file system I can access "System Volume Information" folder but in NTFS I can't.
How can I access it?
|
|
|
|
|
By ensuring that the user trying to access the folder has appropriate permissions.
Right-click the folder then sort out the user access permissions from the Sharing/Security context menu item. Pick the Security tab, then ensure the user belongs to one of the groups that has access, or create a new group that has access and add the user to it.

Hello,
I am having the following routine which handles my menu options and directs them to the appropriate functions.Now if I want to divert these functions through keyboard handlers that ALT F,ALT D etc.
How should I go about?
BOOL CMainFrame::OnCommand(WPARAM wParam, LPARAM lParam)
{
if(HIWORD(wParam) == 0)
{
switch(LOWORD(wParam)) //LOWORD of wParam identifies the control
{
//ids from menu options
case MENUINVENTORY :
{OnInventory();break;}
case MENUJOB :
{OnJob();break;}
case MENUCAPCONTRACT :
{OnCapContract();break;}
}
}
Thanks,
Prithaa

I hope, the only thing you've to do is provide keyboard accelerator to your menu option. To provide keyboard accelerator use '&' character before the alphabet you like to use in combination with 'Alt' key. E.g if you've the menu with caption "Help", to provide 'Alt H' combination, set the caption as "&Help". The 'Alt H' combination will accelerate the menu select option, and you need not to worry about the routine handlers.

Not sure what you mean but if your looking for the default dialog font it can be obtained by changing the font face to: _T("MS Shell Dlg 2") which is a Logical Font[^] that maps to default font used throughout the operating system on Windows 2000 and later.

Hi, I'm trying to do this program in C++ without MFC that creates an owner-drawn listbox with the WS_VSCROLL style. Owner drawing the listbox and listbox items is not a problem, but how do I owner draw the vertical scrollbar within the listbox? Even if I set the listbox style to LBS_OWNERDRAWVARIABLE or LBS_OWNERDRAWFIXED, the scrollbar still seems to draw normally.
Thanks!

That example uses MFC which I am not using in this program, also what I want to do is ownerdraw the internal scrollbar itself, I don't want to superimpose a new scrollbar control over top of the listbox. Isn't there a way to set the listbox's scrollbar to ownerdraw and handle that?
