I am writing a simple windows application and in my main window message processing function I create a child window that is an edit box:
btn = ior(ior(WS_CHILD, WS_VISIBLE), ES_LEFT)
hEdt2 = CreateWindowEx(WS_EX_CLIENTEDGE, "Edit"C, ""C, btn, 101, 134, 100, 20, hWnd, 10, ghInstance, NULL)
This executes correctly and I get a child window that is an edit box control. Note that this child window resides in the client area of my main window; it is not part of a dialog box.
I enter text into this edit box and I want to read that text into a character variable. I tried the GetWindowText(hEdt2, ...) function and that returned an empty string. I tried SendMessage(hEdt2, WM_GETTEXT, ...) and SendMessage(hEdt2, EM_GETLINE, ...), and they also returned empty strings. How can I read the text from an edit box control that is not part of a dialog box?
My bad - I forgot to declare the edit box handle with the "save" attribute. When I did, both GetWindowText and SendMessage (using loc function) worked correctly.
Thanks for your help.
