Hi all,
This may be a newbie question, but I can't find the answer anywhere.
I want to make a capture of the screen, or a part of the screen, that
contains the main portion of the form.
Detecting the screen that contain the main portion of the form is pretty
straight forward, but how do I capture what I need in an Image object?
Another thing, how do you make the program move the mouse pointer and
simulate clicks?
Best regards

To capture the complete screen:
Public Shared Function CaptureScreen() As Bitmap
Dim strKeys As String = "^{PRTSC}"
SendKeys.SendWa it(strKeys)
Dim iData As IDataObject = Clipboard.GetDa taObject()
If (iData.GetDataP resent(DataForm ats.Bitmap)) Then
Dim memoryImage As New
Bitmap(CType(iD ata.GetData("Sy stem.Drawing.Bi tmap"), Bitmap))
Return memoryImage
End If
'-- Unable to obtain screenShot from clipboard
Return Nothing
End Function

Hi Per,
To move the mouse pointer and simulate clicks you can use SendInput function
(Win32 function).

I have trying to code a small console app that will
allow a user to select a window and then create a
screen capture of the window. I haven't been able to
figure out how to do the screen capture part. The
code is as follows, the commented out lines at the end
are things I have tried, but don't work. Whenever I
try to create a compatibe Bitmap or DC it comes back
with an error as

Greetings.
I encountered a wield problem when grabing screen images.
Sometimes in some computers I can capture the screen, but other times not
so.
In some computer I cannot capture the screen image, but when I change its
color bits, say from 32bits to 24 or 16bits, the program can capture the
image.
Can anyone kindly examine my following code, and point out the flaw:

I have seen some examples of how to capture a color from a point on screen
using C#, but haven't come across anything with VB.NET. Is this possible
under VB.NET? I know that I will need to use the GetPixel API in order to
do this.
Essentially, I would like to be able to move the mouse around the screen,
and wherever the left button is clicked, I would like to store the color
value of the point where the cursor is located. If possible,...

I use this code to capture a screen in a regular VB 2005 windows app.
It works great! I found the code in google. But when I create a windows
service it does not capture the screen. It only captures a blank
graphic. Does anyone know why it will not capture the current screen?
Is something not available when running as a service? Thanks!!!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
