display image using gdi

[shred444]

ive been reading a ton of articles about vb.net and GDI, but for some reason, i cant get an image to be displayed on my form.

ive tried everything.

eventually, i want to be able to rotate this image according to sensor inputs, but for now, i am concentrating on just getting this image to appear.

can someone tell me... what headers i need to include, what subs/functions i need, and what variables are supposed to be declared.

I assume you mean GDI+

Me.CreateGraphics.DrawImageUnscaled(Image.FromFile("c:\myimage.bmp"), 0,0)

Check out this thread by the GDI+ Guru

That link has more to do with manually drawing shapes. If you want to draw an image then just use Me.CreateGraphics.DrawImage(MyImage,0,0) nothing else required.

If you want to rotate the image then you need one of the overloads of DrawImage that takes an image and a pointf array as arguments.

thanks guys, i tried the me.creategraphics, but it does not draw the image. i know the image is being found, because if i wereto us a wrong filename, it shows an error.


the form is just a gray form, no image.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CreateGraphics.DrawImageUnscaled(Image.FromFile("C:\Documents and Settings\Cohn\My Documents\My Pictures\eclipse.jpg"), 0, 0)

 End Sub

You need to do the drawing in the forms paint event so it will persist and redraw when the forms state or size change.

is this what the code should look like for the function header?

Private Sub PictureBox1a(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
