Capturing Audio Stops When Main Window Is Minimized Or Obstructed By Another Window?
Feb 9, 2012I have a VB.NET application that uses Managed DirectSound to capture audio.Everything works just fine until (a) the application is minimized or (b) the application is completey obstructed (covered) by another window.
The thing is that the CaptureBufferDescription structure does not include a GlobalFocus property so I don't know what to do to let my application continue capturing when the main window is hidden.
Here's the basic initialization code I'm using:
' Create a buffer description object
bufCapDesc = New CaptureBufferDescription()
With bufCapDesc

Get The Window's Handle Once It Has Been Minimized?
Mar 1, 2012<DllImport("user32.dll", SetLastError:=True)> _
Private Shared Function SetActiveWindow(ByVal hWnd As IntPtr) As IntPtr
End Function
[Code]......
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?
I've tried various functions like FindWindow and BringWindowToTop but none of them seem to work.

Forms :: ListView.TopItem And Minimized Window?
Jun 15, 2011I have an issue in a project trying to auto-scroll down a ListView (used as Details with columns) when adding a new ListViewItem when the window is minimized. I guess we have to use TopItem property to set force the listview to scroll down.I get two exceptions when the form is minimized: "Object reference not set to an instance of an object." "Index (zero based) must be greater than or equal to zero and less than the size of the argument list."
I'm just using standard .Net components (Events/Delegate) with standard way to use them.
I made a small test code to isolate the issue:

Send Mouseclicks / Keystrokes Into Minimized Window?
Mar 3, 2009I know how to send mouse clicks and keystrokes into an application when it is open and active, but this particular application the task is very repetitive and can be done with a script of sorts.

Find The Handle Of The Child Window For The Yes Button In The User Account Control Window?
Mar 20, 2010I 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.

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 would like the user to be able to type in the new value, then press the 'done' key to submit this value and have it sent back to the main application window into my custom control that contains a text box.(I have the number pad's layout sorted out already; I'm already using a variation on it to set a global password 'access level'.
