I want to make a screenshot of a specific window of which I know the handle. I know there is a BitBlt function but I can't get that to work with the handle, I prefer it to work even if the window is not active but I'm not sure if this is possible at all.

I have been working on an image capturing tool for a long time now & I was wondering how some of those programs are able to make an aero capture of a form.I know you can capture a window if you have it's handle by using the BitBlt, but that doesn't keep the transparancy of the aero form.Let me give you an example:I did a lot of research on google but I never found anything close to something that explains how to do it.

I'm making some Aero-style transparent forms (signature), and they work just fine. However, to get a screenshot of the area behind the form using Graphics. CopyFromScreen(), the form has to be less than 100% Opacity, so CopyFromScreen doesn't include the window in the picture. This also means that when you have more than one open, they see through each other.

View 4 RepliesI am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?
I stumbled upon an excellent article about taking screenshots of specific windows in .NET, and doing something with black and white color rectangles behind those windows in order to preserve the aero effect when saving a screenshot to a PNG.Well, I can't find that article anymore, mainly because crap sites and other stuff not at all associated with taking screenshots SEO'd their way into Google's results.Does anyone know how I can take a screenshot of a specific window while preserving the aero effect?
View 1 RepliesI'm working on a UNO (Msn-based) online gaming tool - you know the card game. It's the second version with more features for UNO fans. I would like to get the screenshot function to work.
It's just as simple as this: The UNO main window
The screenshot viewer shows the screenshot of the active window (which appears by clicking on "Screenshot"): (This form is named as "Screenshot", the Picture Box "myPictureBox")
My question is, which code do I need to bind these functions. I think the pictures are describing this good enough. (The "save screenshot"-button is ToolStripButton1, the button for making screenshot is ToolStripButton10).

I'm trying to make use of some functionality from an external app in my program.
My problem is this:
My program manages to start the external app correctly and I can even get the WinHandle correctly if I don't use "ProcessWindowStyle.Minimized" when starting the app.
If I start the app minimized, WinHandle = ProcID.MainWindowHandle returns a 0 and as I understand it, it's
because the app is hidden in the system tray.
How can I start the app minimized and then get the window's handle once it has been minimized?

View 3 RepliesI'm using a third party dll for my project and one of the function that is provided by the dll use form handle as one of the argument. But when i call the function, I'm not using any window form and it's just called from another class. So what value i should put for that argument?Here's the example of that function:
AVS_Measure (device_handle, form_handle, no_measurement)
After this function has been called, it will send message to the form_handle argument whether the measurement data is available and valid.I called this function from another class just for triggering start measurement and i have another function to retrieve the data. I do not have any form associate to it, what value i should put for this argument?
I'm writing a DLL library that interfaces to a USB device using winusb in VB.NET.
Since it's a DLL, I have no window, and it's possible that users of my library will also not have a window (command line apps, for instance).
The examples I've seen that detect device attach and detach all use RegisterDeviceNotification which requires a window handle to receive the attach/detach messages at.
How do I receive these messages directly into a function without a window to get a handle from?
I have the below code. When I execute this code, the handle is different between the Load event and the Shown event. I thought the handle was static for an instance of a window. What could cause the handle to change? The only other thing the form is doing is setting itself to invisible and setting the ShowInTaskbar = False in the Activated event.
