System.Drawing.Bitmap

Hello, how would I display a System.Drawing.Bitmap on my form.. Or on something... Theres no BitBlt in .NET...

say I had like: Dim P as System.Drawing.Bitmap

I tried making a picturebox but I couldn't figure out how to make it show whatever P was... I'm confused heh


Thanks,
Jake

Code:

---

box.Image = New Bitmap("filename")

---

But then how would I use the functions in system.drawing.bitmap? Like getpixel or maketransparent..

Something like this :

Code:

---

'Class variable
Private myBitmap As Bitmap
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

        Me.myBitmap = Bitmap.FromFile("c:\test.jpg")       
        Me.PictureBox1.Image = Me.myBitmap
        MessageBox.Show(Me.myBitmap.GetPixel(10, 10).ToString)

End Sub

---

Ok thats what I figured.. So then I'd have to do this..

VB Code:

Dim B as Bitmap
 
B=B.FromFile("C:\a.bmp")
B.MakeTransparent(RGB(0,0,0))
Picturebox1.Image=B

And everytime I changed something in B, I'd have to use Picturebox1.Image=B.. No biggie.. Is there anyway to bind the picturebox1.image to B, so if B changes, picturebox1.image changes too? Maybe Set PictureBox1.Image = B?

Actually, I'd only have to use P.Refresh every time. That means that P.Image IS "set" to B. Whatever changes on B changes on P, but P needs to be refreshed. Is there some kind of autoredraw on pictureboxes? Or images or something?

AutoDraw's gone . It's was useful in VB6 . The only convenient solution I can think of now is using events .You simply raise an event whenever you change/call any method of Bitmap obj . Then you put your code that respond to that event in the event handler .
