View 8 RepliesHow To Check If PictureBox Is Completely Loaded
Apr 9, 2010I have a form which contains a tab control with three tabs on it. On a second tab there is a PictureBox. The problem is I can't figure out how to check if the PictureBox is completely loaded.I can't put "pictureBox.CreateGraphics.DrawRectangle(Pens.Aqua, 100, 100, 100, 100)" into a form load event because picturebox is not active until I click on the tab2. It neither works with tab2.enter event nor any other events I have tried so far. However it works through the button.click event and it works briefly with the picturebox.paint event before its wiped out. So I presume it will work with a timer event as well.But the question is how to to make it work without a button or a timer?

Moving PictureBox And Increment Score When Passes Over Object
Feb 20, 2012Trying to write a very simple game moving PictureBox2 around with keys and when it passes over another object such as PictureBox1 the score is incremented and then PictureBox1 is disabled/removed. Problem is that it disappears but every time you pass over that area it still increments the score further as if the object was there still.
Here is current code, but have also tried hide, dispose and Controls.remove with no luck.
If PictureBox2.Bounds.IntersectsWith(PictureBox1.Bounds) Then
score = score + 1
Label1.Text = score
PictureBox1.Enabled = False
PictureBox1.Visible = False
