Message Box

I would like to create a message box that appear for a few seconds and closed by itself without the users interfering. How am I going about doing that?

Thanks in advance.

One way is to create your own dialog as a message box.
In OnInitdialog start a timer, initialize the timer.
handle OnTimer, which will be called when timer is over where dialog will destroy itself.

That is the most common approach and is quite effective. Just make sure you properly handle the possibility that the user may close the dialog BEFORE the timer expires!!!!!

or use a normal MessageBox and PostMessage the Enter Key

HWND hwnd= FindWindow(messagebox_classname_IDK, NULL);
PostMessage(hwnd, WM_KEYDOWN, VK_ENTER, 0);

use Winspector Spy or Micrsoft Spy++
make the messagebox trigger then look at the messages to find the classname

Why don't you use the well-known MS sample ?!

1) Please use code tags!!!!!

2) You STILL need a timer to execute this code.

3) the race condition I mentioned earlier may occur.

4) It is a more complicated solution that neccessary.

5) It is more tightly bound to the platform API's than necessary.

How does that keep the message box open for a certain period of time?
