Thread: Edit box not working

Here is my code for creating an edit box:

Code:

CreateWindow("Edit", "Test", WS_CHILD|WS_VISIBLE, 100, 300, 100, 20, hwnd, 0, 0, NULL);

hwnd is a valid parent window.

It apears and apears to work fine but I am not able to type or delete stuff inside the textbox. I already figured out that read only is not the problem, anyone got other ideas?
