cant modify edit box text

[UberTron]

Hi, I have created an 'edit' window using the following line:

edit = CreateWindow("EDIT", "", WS_VISIBLE | WS_CHILDWINDOW | WS_BORDER | ES_CENTER, 4, 4, 296, 20, hWnd, edit_id, hInst, NULL);

And declared edit and edit_id as follows:

HWND edit;
HMENU edit_id = (HMENU)50;

I see the 'edit' window when i run my program but when i click inside of it to add text nothing happens. nomatter what i click on the keyboard no text is inserted in the box. If i start with initial text in the 'edit' window i can delete the text by pressing 'Delete' on the keyboard but i cant put in text of my own. HELP?

oh btw, you should know that i am trying to avoid using a RC file. I can make edit box's work fine in the standard Win32 application that visual c++ makes for you, but i am trying to strip that code down into something simple i can understand

[some random dude]

Try calling TranslateMessage (&msg); right before DispatchMessage (&msg);

UberTron is correct. The editbox will not work right with out TranslateMessage() with out it, you deliver raw char data to the editbox.
