Vb.net – How to rotate a PictureBox on a windows form using vb.net

vb.net

I need to rotate a picture box 180 degrees when a condition in my if statement is met. Is this possible?

I'll assume that you want to rotate the image inside, because rotating the box itself doesn't make much sense (and is impossible anyway).

Try this:

myPictureBox.Image.RotateFlip(RotateFlipType.Rotate180FlipNone);

I guess that depends on what you define as being "anything too nasty" :-)

The PrintDocument class has a Graphics object you can use for this, which in turn has a TranslateTransform and RotateTransform method that will allow you to get things where you need them to be.

It's often worth taking a copy of the graphics object before you manipulate it so you can restore it back again when you're done.

Use the AddHandler statement to subscribe to the Click event:

    AddHandler pic.Click, AddressOf pic_Click

The sender argument of the pic_Click() method gives you a reference to the picture box back:

Private Sub pic_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim pic As PictureBox = DirectCast(sender, PictureBox)
    ' etc...
End Sub

If you need additional info about the specific control, like an index, then you can use the Tag property.
