George,

>VB forms have an hWnd property. To simulate the LockScreen property. Declare the API function LockWindowUpdate() (it's in USER32.DLL) and pass it the form's hwnd property. To "unlock" it, call the same function with 0 as the parameter.

I've used this LockWindowUpdate() function to lock updates for various activex controls. Though this seems to work for the locked window, it causes a flickering for the other windows in the desktop when releasing the lock.

Do you have the same experience, or do you have another workarround to prevent the flickering ?

Walter,
