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?
View 2 RepliesI 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?

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.

View 5 RepliesI 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.
View 2 RepliesIt has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.
I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.

View 2 RepliesI want to know if the Windows Run key pressed. How can it be possible? What's the constant or ascii code for this key? The second: How can I know if the program, I wanted to use, is activated? What's the correct func. for this?
View 2 RepliesI have created a program which should perform a certain action whenever a certain group of keys is pressed at the same time. The program must be able to run in the background, or in the system tray or something. Essentially, this should work like the KeyDown event on a form, except the form in this case is everything.
I'm not certain if there is a way to do this directly from within the .net API, but if there is I certainly have not found it.

View 1 RepliesI've tried everything to set my window as active after I've been working on another external App... I have my system on auto and need to send some keystrokes to the program using sendkeys, so I need that app active. I've tried almost everything I can think of, bringtofront, setfocus, windowstate, setactivewindow, setforegroundwindow (For the last 2, hwnd doesnt work - I'm using VB 2008 Express) but none of them seem to be working.
View 4 RepliesI am trying to have any only one form type eg Countries, Projects, or Vendors etc. open at the same time. So, if a user has the Country form open and goes to open it again from the menu I would like the applaication to bring the form to the Front of the MDI container. I have tried a number of things like BringToFront, ActivateMdiChild, etc.

I'm having troubles with terminating an application. When I close the main form everything disappears but the process remains active. I think I know the cause, a certain activeX component will not release properly. As soon as I create one, I can't close normally...
dim someActiveXcomponent = new X()
...
<formClosing>
someActiveXcomponent = nothing
GC.Collect()
GC.WaitForPendingFinalizers ' here it hangs
Probably a bug in that component, but the problem is that I don't have much of a choice, I'll have to use that component for now.
Calling
System.Runtime.InteropServices.Marshal.ReleaseComO bject( myObject )
will kill the reference and now the application closes properly.

View 11 RepliesI want to make an application that allows the manager of the company whether the employees are truly active: screenshot and a "timer" to measure the time of the activity of the employee Can be controlled using the mouse or keyboard while the application is not active, but in execution.Is it possible in vb.net to know if the user of the machine is using the mouse or keyboard? My idea is to set a "Timer" which triggers automatically after the connection of the employee and every 10 seconds the application checks whether the mouse position has changed or a letter is entered on the keyboard except the"Timer" Will Be stopped until have a new mouse position or activity on the keyboard. But the problem is: is the application able to know the position of the mouse or to capture all keyboard input even if the application n 'is not active(not in the foreground)?

View 2 RepliesI would like to put an active login form where by if one fails toput the correct password after 3 trials the program exits
View 1 RepliesI am writing an application where active directory validation is required before accessing the main form. There are 2 forms. Form 2 is the login form and form 1 is the main form. The main form would have a simple look, with about 10 checkboxes.I have managed to get the authentication working great but what now need to do is validate groups. Say if "user A" is in "groups A,B and C" and "user B" is in "groups B and C" i would like for them to use my login form, once they log in, the groups that they are members of would appear in a listbox on either form, (whichever is easiest) and is hidden from the user ... if they are in group A, then the main form would show only the first 3 checkboxes, if they are in group B, then it would show the 4th and 5th checkboxes, if in both groups then show the first 5 checkboxes etc.It is a simple idea, but is complicated to explain.As i said, the login form is working with the active directory... here is the code for the login form:[code]Form1 in the code is my main form, and wish for it to change according to which groups the user is in.
