    Making Controls Editable/UnEditable

    Im working on a Win32 program in C, and I don't know how to set this check box I have as unedit/editable. I want it to start about being uneditable, and then when the user clicks certain buttons, I want it to become editable. THis is how my check box is defined when the program starts.

    hWndButton = CreateWindowEx(
    0,
    "BUTTON",
    "Swap Byte Order",
    WS_VISIBLE | WS_CHILD | BS_AUTOCHECKBOX,
    10,
    80,
    130,
    20,
    hwnd,
    (HMENU)ID_CHECK_BOX1,
    hInstance,
    NULL);


    If someone can help, i would really appreciate it.

    Thanks

    I'm not clear about what you're asking but there seem to be two possibilities.

    If you're looking just to set the check state of the checkbox then BM_GETCHECK and BM_SETCHECK are the messages you'll be interested in.

    If, on the other hand, you're attempting to change the checkbox caption then just use SetWindowText as required.

    If none of that seems relevant to your query then you'll have elaborate.

    Well lets say the user clicked the check box, if it were uneditable, it would do nothing, the user would not be able to do anything with it. it would be greyed out basically. thats what i mean

    Use the EnableWindow function to set whether it's enabled or grayed, then.

    Aiight. If you wanna start that thing you posted above as grayed, then you declare it as:-
    Code:
    hWndButton = CreateWindowEx(
    						0,
    						"BUTTON",
    						"Swap Byte Order",
    						WS_VISIBLE | WS_CHILD |  WS_DISABLED | BS_AUTOCHECKBOX, // note new style entry
    						10,
    						80,
    						130,
    						20,
    						hwnd,
    						(HMENU)ID_CHECK_BOX1,
    						hInstance,
    						NULL);
    Then, when you want to enable it, just call:-
    Code:
    EnableWindow(hWndButton, TRUE);
    To disable it, change TRUE to FALSE.
