You don't always want to 'toggle' the control. In most cases you want to set the enabled state (after some event or in a certain case).

Anways, you could use something like this:

code:

---

function ControlEnable(pPlusWnd, sControlId, bState) {
    // Get handle of the specified control on the specified window
    var hCtrl = pPlusWnd.GetControlHandle(sControlId);
    // If function is called with a 3rd parameter, set the state of the control
    if (arguments.length === 3) Interop.Call("User32", "EnableWindow", hCtrl, bState);
    // Return the current state of the control
    return Interop.Call("User32", "IsWindowEnabled", hCtrl);
}

---

Usage:

example 1: Disable control:
ControlEnable(mywindow, "mycontrol", 0);

example 2: Enable control:
ControlEnable(mywindow, "mycontrol", 1);

example 3: Get current state of control:
var TheState = ControlEnable(mywindow, "mycontrol");


---------

Or even (to add the toggle functionality):

code:

---

function ControlEnable(pPlusWnd, sControlId, bState) {
    // Get handle of the specified control on the specified window
    var hCtrl = pPlusWnd.GetControlHandle(sControlId);
    // If function is called with a 3rd parameter, set the state of the control
    if (arguments.length === 3) {
        // If bState doesn't equal 0 or 1, toggle the state of the control
        if (bState != 0 && bState != 1) bState = Interop.Call("User32", "IsWindowEnabled", hCtrl) ^ 1;
        Interop.Call("User32", "EnableWindow", hCtrl, bState);
    }
    // Return the current state of the control
    return Interop.Call("User32", "IsWindowEnabled", hCtrl);
}

---

Additional usage to the above examples:

example 4: Toggle control:
ControlEnable(mywindow, "mycontrol", 2);
