I am creating my textbox with these options. I can copy/cut/paste/undo, but when i hit select A it doesnt select all. I can right click and click select all but ctrl a doesn
You could simply use EM_SETSEL message to the textbox,
According to MSDN ,
If the start is 0 and the end is –1, all the text in the edit control is selected. If the start is –1, any current selection is deselected.
so,
SendMessage(hwndEdit,EM_SETSEL,0,-1);
Will work fine.
