Capturing Audio Stops When Main Window Is Minimized Or Obstructed By Another Window?
Feb 9, 2012
I 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
So I have a wav playing using DirectX in VB6. If i switch to another window, it stops playing. If I click back on the VB6 window it resumes play. How do I make it continue playing when I change windows? Another problem I cannot load wav files larger than 50 megabyte. It says Out Of Memory. How can I increase that?

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.

But its like chinese for me.my goal is to run these little programs by the 100's on 1 pc. and they just press a key in their own application , over and over.i was thinking something like this
Private Declare Function PostMessage Lib "user32.dll" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long Private Const WM_CHAR As Long = &H102 PostMessage("notepad", WM_CHAR, "T", 1)
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 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 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?
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]...

What I need to do is Set my new form to be the top most form of only my application while still having click access to the main form. Right now I have tried the property Topmost = True but the thing about that I really do not like is it puts the form above every single windows form. I only want the form to be the topmost of my application. The showdialog also will not work because I no longer have access to my main form with click events.
Trying to replicate the docking controls in Visual Studio 2008. My application replays the RADAR environment for the FAA and I want the ability for dual monitor users to drag the control panels to the other monotor to leave the main canvas clear. This functionality is similar to the way the different panels in VS can be dragged outside of the main window.

I am having a difficulty in this login form that I have made. The same as the premade template login in VB 2008 which I am using right now.Here's what happens when I run the program Log in form open > Log in successful > Main window appears *The login form still does not disappear.
I tried hiding it via me.hide() Log in form open > log in successful > Main window appears > log in form disappear.*Now the problem is that I cant close the whole application because the login form is still there only hidden. Again I tried putting in the "EXIT" button the code me.close() login.close()Log in form open > log in successful > Main window appears > log in form disappears > Exit application *Now everything seems to be ok now and then I found another problem.Instead of clicking the exit button I tried clicking the X button on the main window. There I found out that it only closes the main window. Therefore not closing the whole application because the login form is still hidden.
i made an application in VB2010 where the application should be always on top above one specific window. Anyway i set the property of the main form to "topmost = true". The application is also writing some data to excel which is not a problem but the excel workbook is behind the main form which is on top. Is there any way to put the excel window on top above the main form?
I have set the Visibility property of the main window to Hidden and added the following in Window_Loaded: private void Window_Loaded(object sender, RoutedEventArgs e){ this.Visibility = System.Windows.Visibility.Visible; } But it doesn't show up the Window.
I am working on a game launcher, and I need to display a "Splash screen" until the main game has started. For this, I need to know whether or not the Process has a Main window that is fully loaded and displayed.Now I noticed the main window handle is 0 when there is none, so I tried to use that:[code]But the handle never becomes nonzero. I tried to use the title but to no avail.I do not want to go into "Thread.wait()" since then the splash would remain even if the game is already launched.
