Active Form In Windows Application?

Oct 7, 2009

I am developing a Windows Forms application. I have four forms which is inherited from Baseform in another project. In all four forms I am using a label to show some transaction count based on network status. I have implemented a thread which gets the active form of application and setting up the text. The code works fine if application screen is active. If I minimize and open any other application, I am getting an null error exception.

How do I get the active form of an application?
Private Sub StartThread()
pollThread =New Thread(AddressOf PollfileStatus)
pollThread.IsBackground =True
running =True
pollThread.Start()

MDI Application - How To Get Active Form

Mar 11, 2010

I have a mdi application. When some childforms are open (but only one is active) and the user press a button, I want to know, what form is open, because depending on this, an event will fire up. I imagine this so: at first I determine the active form with a separate function. And then with a select case statement the event will be fired up. How can I make this?

FlashWindowEx Doesn't Work While The Application Is Active But Does When Another Application Is Active

Apr 2, 2010

I have a standard Visual Studio 2008 VB.Net WinForm application, running on Vista Business. One of the forms has a timer that passes Me.Handle to FlashWindowEx. This works as intended as long as none of the windows that belong to this application are the Foreground window. If this program is running and another application's window is the Foreground window, then it flashes as intended. If, however, any of this application's windows are the Foreground window, then it doesn't flash.

'abort' (terminate Immediately) A Form Screen In A Windows Form Application Running Under 'local' Environment?

May 30, 2012

FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]

VS 2010 Retrieve Currently Active Application Window From Another Application Just Starting Up

May 26, 2011

I am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.

Terminating A Windows Form Application?

Dec 18, 2009

What is the proper way to terminate a Windows Form application while it is just executing in the MyApplication_Startup routine?I have an application that looks for a database file upon startup. If it does not find it I prompt the user and ask if they wish to locate the file or not. If they choose not to locate the file I want to just terminate the application. Currently i just execute the "End" statement, but that does not seem like the proper way to terminate a program.
