This little project took me hours and hours to complete but I think was worthy if only for the learning experience.
The project as such won't be of much use to most excel users but its shows that vba can do all kinds of neat things when combined with the win32 API.
This is what the code does:
* Allows moving and\or copying userform controls at runtime.
* The semi-transparent control that follows the mouse pointer during a dragging operation is actually a win32 static control (This static control, not being a child window of the userform, was the most tricky part to make it a layered window and to keep it confined within the bounderies of the parent form.)
* A colored dashed frame is drawn around the static control.
* The cursor changes dynamically depending on moving the controls , copying them (Holding CTRL key down) or when -the image is being moved outside the parent form. (custom cursor not showing on the Gif below but works as expected in the file demo below)
* Right-click context menu for deleting the controls.
* A label control can optionally be integrated into the class for displaying the current user activity.
This is the signature of only Class Method that hooks the UserForm controls:
Public Sub HookControl( _
ByVal ThisClassInstance As cls_DraggableControl, _
ByVal Ctrl As Control, _
Optional ByVal UILabel As Control _
)
Note: The transparency of the static control won't work unless the Desktop Window Manager (DWM) is enabled in the machine running the code.
