cardx

code block of the source code: This.picturebox[x,y]. Click + + new System.EventHandler (this. Usertapsscreen); As you can see, I added the same function to each control (Usertapsscreen). The obvious question is, "in this function, how do I know which control the message is emitted from?" "Here's the source code to do this: private void Usertapsscreen (object sender, System.EventArgs e) { int CARDX =-1; int cardy =-1; Find the "card" send the mess

The first: In the queue of the card only you are selected, will respond to their own visible area, and the previous card in the lower part of the visible area.This is the simplest, when you are selected, first change the normal visible area and then + Select the visible area.When selected we change the y-coordinate of the card: the y-coordinate of the card = the y-coordinate of the card-checkhigh (the upward height after selection)And then substituting the followingNormalrect.setrect (The x-coor
