I am making a program to automatically take and save screen shots and I am using the F12 button. It works fine, but the problem I have is when I press F12, it will take and input the picture into the PictureBox1, but if I try to clear it, and then do it a second time, it wont work a second time. My clear button code is:
Picturebox1.dispose()
I am looking to create simple application that means that when the 'Print Screen' button is pressed, the screenshot is not just sent to the clipboard but saved to the desktop in either JPEG or PNG format.The application will run at startup so that the 'new' print screen functionality is there but the interface of the app is opened manually.(the app interface includes simple options such as choose where file is saved.)

View 14 RepliesIs it possible to use the KeyDown on a picturebox?What I want is that when somebody presses the SPACEBAR the cursor has to change in the Hand-icon...and additionally do some operations when moving over the picturebox. I fact...when spacebar hasn't been pressed you can just move around the picturebox, without anything happening...with the spacebar pressed the cursor should change and you should be able to scroll the image using the mouse moving.
what I have is :
