PaintPicture -- How??

[Anagnos]

I recently got VB.NET, and now I need to somehow use the PaintPicture
command from VB6. Obviously it does not exist in .NET. I would do this
in 6 but I need to use pngs as images, because only they support
semi-transparent pixels.

Thanks in advance,

Hi,

Take a look at the graphics class drawimage method.

The help says that you can use the drawimage but i'd rather not have it
as an event, is there anyway to just use a line of code for it? Or even
a way to call on the PaintEventArgs event?

Hi,

Try something like this.

Dim g as graphics = picturebox1.creategraphics

Thanks,

Unfortunatly this still does not work, the form loads fine but nothing
happens. here is my code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Dim g As Graphics = PictureBox1.CreateGraphics


PictureBox1.CreateGraphics.DrawImage(System.Drawing.Image.FromFile("C:\D
ocuments and Settings\Telemachus\Desktop\1.png"), 1, 1)

End Sub

Hi,

The load event occurs before the paint event. So the paint
event erases the stuff drawn in the load event. If you want the picturebox
to redraw itself set the picturebox image property.

PictureBox1.image = Image.FromFile("C:\Documents and
Settings\Telemachus\Desktop\1.png")

Thanks, I got it working just by delaying the code with a timer. Thanks
again.

Thanks, that works but I am going to end up needing to have multiple
images in the picture box. Any way to do that?

Use the Paint event of the picture box. Every time the picture box needs
updating it will fire this event and then you draw your picture(s).
