i have an mdiForm. it has the standard "windows" menu option, thats lets you change the layout of the child windows, it also has the list of currently open windows. is there a way to access that code that generates that list so i can alter so that is window from the list is selected and it has been minimized, it wont just set the focus to that window but open it to the normal state?
View 1 RepliesI 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()

I have an application I run on a netbook that is folded up inside a robot.Occasionally, something from the system tray will pop up unexpectedly. This removes the focus from my application I also thought there was a way (in forms properties in the vb6 days) that would allow to "run when minimized"? In short, I want this application to be running and nothing (asides an application error message) else getting in the way.
View 4 RepliesI have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.

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 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 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]...
