Question

Assuming that I’m in a function that is called in a Timer on in Windows Forms class… how can I tell if the user is currently attempting to ‘Drag’ something?

example:

public void SomeMethod() {     // This doesn't exist of course :)     if (Mouse.IsDragging) ... } 

EDIT: I should specify that I know that I can override DragEnter and DragLeave to set my own private variable… but I’m asking/looking for a ‘.Nety’ solution if one exists.

Easy:

        bool mDragging; ...             mDragging = true;             DoDragDrop('test', DragDropEffects.All);             mDragging = false; 

Universal:

    public static bool IsDragging()     {         StackFrame[] frames = new StackTrace(false).GetFrames();         foreach (StackFrame frame in frames)         {             System.Reflection.MethodBase mb = frame.GetMethod();             if (mb.Module.Name == 'System.Windows.Forms.dll' && mb.Name == 'DoDragDrop')                 return true;         }         return false;     }
