Richtextbox to Image

[Mansi Shah]

Hi,

I have one pictruebox on which there is richtexbox.
When i print the picturebox it is not showing richtextbox in print.
It seems that printing richtextbox needs some more code to be added.
Is there any way by which i can convert richtextbox to image or bitmap,
so that i can print that?


Regards,
Mansi Shah.

You can capture r as rectangle into bm as bitmap like this:

bm = New Bitmap(r.Width, r.Height, Imaging.PixelFormat.Format32bppArgb)
Using g As Drawing.Graphics = Drawing.Graphics.FromImage(bm)
g.CopyFromScreen(r.X, r.Y, 0, 0, r.Size, CopyPixelOperation.SourceCopy)
End Using

You may have to twiddle the PixelFormat parameter.

Every control has a DrawToBitmap function which returns a bitmap.

However, note that this approach will only work if the relevant portion of
the richtextbox is visible.

For more complex scenarios, using 'EM_FORMATRANGE' might be an option:

The target DC could be those wrapped by a 'Graphics' object.
