i want to create a vbnet image and change the motion by clicking on the image

I want to create an image at Form1_Load and change the motion by clicking the moving image.
After displaying the image, you can change the movement by pressing a button, but you cannot click the image directly and move it individually.
It is an ugly code, thank you.

  • Answer # 1

    The image seems to be written in the PictureBox, so it should be changed in the Click event of the PictureBox.

    Adding event handlers
    If you search like this, various explanation pages will appear.
    Also see the AddHandler statement.
