I'm learning mfc recent now. And I get a word quit confuses me , "hook"! it appears it the "chapter Window Messaging" of " programming applications for windows 4th edition"
quotion below:"
Let's start off with some ground rules. Windows allows a single process to create up to 10,000 different types of User objects: icons, cursors, window classes, menus, accelerator tables, and more. When a thread calls a function that creates one of these objects, the object is owned by the thread's process. So, if the process terminates without a thread explicitly destroying the object, the operating system will automatically destroy the object. However, two User objects—windows and hooks—are owned by the thread that creates the window or installs the hook. So, if a thread creates a window or installs a hook and then that thread terminates, the operating system automatically destroys the window or uninstalls the hook.
"
what does "hooks" meaning ? thanks!

Hooking in this sense means getting notification of specific window (creation, initialization, etc.) and being able to get access to (or intefere with) with the data associated with that event as well as being able to do additional processing.
Look up the hook-related functions like SetWindowsHookEx(...) for more details. MSDN also had documentation on "Windows Hooks" that wil be useful to you.

just wondering, why are you exposing your DllMain() function in your .def file ?
AFAIK, no one should call it explicitely (the system does it) so there's no need for any one to see its clear name (even the mangled name is not shown in normal cases i believe)

Hi All,
How do i determine whether my application window has the focus or not?

Try using CWnd::GetFocus .

Use GetFocus() which returns the CWnd* object which currently has focus...
So you can compare likewise...
bool <code>CYourMainWindow</code>::IsFocussed()
{
return GetFocus()->GetSafeHwnd() == this->GetSafeHwnd();
}
|
|
|
|
|
GetFocus() returns a HWND. I am not sure about this???

MFC version of GetFocus() return CWnd* .
|
|
|
|
|
Don't compare CWnd* values to tell if they are the same window. Call GetSafeHwnd() on both and compare the HWND s.

Yes you are right and dang! what was I thinking. I should compare HWND's. Thanks Michael.

As far as i can see, all is well. No problems what so ever.
If you would like to see what happens inside your program, run your program in debug mode.

Hi all,
I want to know whether a function exists that can invoke a messagebox with a editbox inside of it (From a WIN32 console application / without using MFC)??
Makes sense ?
Thanks
Regards,

Hi,
Better u add one more dialog with an edit box in it. Make it as a child, then you can use it just like MessageBox by calling the dialog in appropriate places.
CMyDialog *dlg = new CMyDialog();
dlg->Create(IDD_DIALOG1, NULL);
dlg->ShowWindow(SW_SHOW);
use this in places where you would like to call the MessageBox.
Regards,
Syam.

This might be a very stupid question, but isn't that MFC ???
I'm looking for a way to do it in C or C++
Many Thanks for your response.

Yes MFC. No way in pure C++. Noreover, Standard C++ language has no GUI support.
