bitblt_bitblt 拉伸_bitblt srccopy

I'm now simply trying to convert the code above (as well as the code in the various source-code files) into a single .vb file (through notepad and the command prompt compiler) that can accept a filename/location as a command-line argument (once compiled obviously) to provide a location to save the image. However, I'm currently going nowhere fast and I am looking for some guidance (specifically towards what I should cut out since I don't need any forms or picture boxes, and then how to accept the command-line argument). Thank you.

Hi,

if I copy and paste the function

Function copyRect and build

it breaks at the line

BitBlt(HDC2, 0, 0, rect.Width, _

rect.Height, HDC1, rect.X, rect.Y, 13369376)

with the error message

Value of type 'System.IntPtr' cannot be converted to 'Integer'.

Is it because my vb.net version is 2002?

Anyone have any ways around it?

This example project is great if I want to copy images a small number of times. If it is used repeatedly though I start to have problems with lack of memory and my whole system slows. e.g. if the second button is amended to copy the image 1000 times. Windows task manager shows large amounts of memory used that isnt released until the form is closed and the gdi objects count goes up to 2000+. I'm using Win 2000.

Does anyone know the reason for this?

(note: fixing the typo identified earlier has no effect on this)

Mike

This code helped me a lot solving a problem, creating a graphic and storing it in a bitmap.
