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. What i want is how do i make a program to be able to send inputs (key clicks) into the application when it is minimized (the application minimized that is). doing this minimized would then allow me to do other more important things whilst the vb program is sending instructions into the other app.[code]...

Mar 16, 2012I'm trying to develop macros for games. I'm currently coding with vb 2010 and I'm using the keybd_event API. It works great, I've done many working macros but I cannot find a way to send arrow strokes using this API. (Left, Right, Up, Down) I don't want to use the numpad. Here is what I've found: [Code] For some reason, nothing happens, no keystroke seems to have been sent. When I use any other ascii decimal from the ascii table, it does work but not for the arrow strokes.
View 2 RepliesCapturing 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:

View 4 RepliesGet 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.

Send Keys To External Application While Minimized
Feb 28, 2012currently my VB Skills aren't so good so bare with me here. application to be able to send keystrokes to another without having it popup. Like it should remain minimized, it shouldn't interfere with whatever you are doing on your PC while it sends the strokes. I received this request from some one else to do. So basically I just need to get focus to the application while it remains minimized and send keystrokes.
View 4 RepliesForms :: 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.

How To Get Unfocused Key Strokes
Jul 1, 2010What I am doing is making a key shortcut program where the user can set that if he presses a certain key combination from anywhere on his computer while the program is still running, a defined action or program will execute. I know how to use the keyup or keydown to get the key input when the form is focused but how do you get the key input when the form is not focused or hidden. The form will be minimized to an icon in the system tray. I have not started working on the program yet since the whole purpose of the program is this.
View 2 RepliesSend A Keystroke To A Window?
Oct 21, 2010I'm trying to send a keystroke to a window (of an external executable) but am having problems.
If I launch the exe with a window I can successfully send it a "q" (in order to make it exit) using the follow:
1) AppActivate and SendKeys
2) SendMessage API using WM_KEYDOWN and WM_KEYUP
3) AppActivate and keybd_event or SetForegroundWindow and keybd_event
However, if I launch it without a window, obviously method 1) does not work as SendKeys only work on applications with visible windows, but I thought that method 2) would work. However, it doesn't. Also, using method 3) with SetForegroundWindow as this seems to only work with visible windows, which is not really a surprise I guess, given the name.
Another method I have tried, which won't work is using the RedirectStandardInput - I have this working correctly, but the application is looking for keyboard events, not writes to its StandardInput stream, so this doesn't have any effect.
Finally, I have tried using SendMessage and FindWindowEx, and TranslateMessage, to find any child windows or controls that should be receiving the messages, rather than the main window. However, no child windows or controls are found, and I wouldn't have thought this would be the solution given that, if the window is present, the main window receives the message as it should.
So, I have confirmed that the messages are going to the correct window, as they arrive as they should when the application is launched with a window, but I cannot get the application to receive the message when it is window-less. The solution doesn't have to involve messages, or even be particularly robust, but this is what I have tried so far (all the obvious stuff!)
