I'm having a bit of a problem with coordinates and mapping PictureBoxes. Here's the situation:

I've got a PictureBox holding an image of a football pitch. The aim is to record the shot positions on this pitch. So whenever the mouse is clicked on the pitch, I am recording the X and Y coordinates of the mouse at that time. This means that when I read from the database, it plots the shots accordingly.
The problem I am facing is when the form is moved from the top left corner of the screen.
I have the form set at 1024x768px - a fixed size. If the form is moved from the left corner of the screen, the shots are placed wrongly due to the coordinates changing.

I understand that the code that I am using is getting me the screen coordinates:

XPos = Control.MousePosition.X - 6
YPos = Control.MousePosition.Y - 27

What I am looking for is a way to get the coordinates relative to the form itself. This would mean that anytime I pull the coordinates from the database, they'll be correct no matter what the form's position is on the screen.

Any help would be appreciated.

Use PointToClient.

If you want the coordinates relative to the form Use:

Dim clientPoint as point = Me.PointToClient(Cursor.Position)

If you want the coordinates relative to the picBox Use:

Dim clientPoint as point = PictureBox1.PointToClient(Cursor.Position)
