i have a small app where users can draw shapes in a picture box using the mouse. I want the 'delete' key, when pressed to delete the current shape. But there is no way (that i can see) to be able to listen to key events for a picture box.

Any ideas around this?

Hi speedie,

There is a property called “KeyPreview�for a Form which determines whether keyboard events for controls on the Form are registered with the Form. Please set it to “True�and try again so that the events work correctly.

“KeyUp�or “KeyDown�events will determine if “Delete�button is pressed (KeyPress event didn’t get fired in my app).

Thanks,

Hi,

I could see thatthere is no keyboard related events for a picture box. If I am not wrong I think you could handle the keypress event of the Form (container of the picture box) and somehow associate to your picture box.

I thought the same, i had a little play around today (had some other pressing problems so not so much time), but the form has a panel which is dock:fill. It appears the form never responds to a key press.

I put an event listener on the form for keypress, with a breakpoint and i never kicked in.
I then thought "aha, put it on the panel" but panel wont accept keypresses the same as the picturebox.

Thanks alot, that 'keyPreview' has done the trick.

Sending good karma to the universal time space you occupy today

Hi,
I am also facing a similar kind of problem and tried“KeyPreview" property but it did not work out.
I have a picture box called PictureBox1 which along with a Horizontal and a Vertical scroll bar is placed onto another Picture Box called MyPictureBox.MyPicturebox is thus a user Control and this User Control opens inside a Form called frmMain whose“KeyPreview" property is set to true.
I want to capture the keypress events of picturebox 1 n e ideas??
:(

Hi,
My problem is solved.Did a silly mistake,focus was not set on the inner picture box and so it was not working.
