Forms :: Process MainWindowHandle - Simple GUI Form To Hide / Show / Minimize / Terminate / Force Terminate
Sep 11, 2011
I have a simple GUI form to hide / show / minimize / terminate / force terminate Processes. i can do all well but for show and hide i need the MainWindowHandle to show or hide it
So here is hide process code:
Dim Proc As New Process = Process.GetProcessesById(List.SelectedRows(0).Cells(1))
Dim hwnd = Proc.MainWindowHandle
ShowWindow(hwnd,0)
If i try the same with show code:
Dim Proc As New Process = Process.GetProcessesById(List.SelectedRows(0).Cells(1))
Dim hwnd = Proc.MainWindowHandle
ShowWindow(hwnd,9)
The MainWindowHandle become 0 cuz its hidden is there is any other way to get the MainWindowHandle of Process ?
I have just built a full main menu for my pc game and need to terminate the running program using a button held within the form. I have built a button labeled exit and tried a couple of closing codes such as: Me.Close ExitApplication
I have a DLL that copies an Access database, opens it, reads it, and then closes it. The second time through it is unable to copy the Access DB because the EXE has an open handle to it. The EXE does not reference the Access DB at all, it just has the open handle because it calls my DLL. After I close the DB, I would like to terminate the EXE's handle to the Acess DB. BTS - I wrote the DLL and it is my Access DB. Another company wrote the EXE and I can not make any changes to it.
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.
I am working on a Windows Service project that is supposed to start automatically with Windows and it has a timer to check if a certain process is created (in this case "iexplorer") the service should terminate that process. In addition, the user should not be able to stop the windows service.
I was able to create the process and make start with Windows. I changed the property (CanStop) to False but that did not help because after a few tries the servise stops. I used a For-Next loop in the timer to check for the process to terminate but unfortunatly, it didn't work. The code I used is:
Dim theProcesses() As Process = System.Diagnostics.Process.GetProcessesByName("Iexplore") For Each currentProcess As Process In theProcesses
I got exactly the same situation as the following link. I need to end the excel process after calling it in Visual Basic. But it did not and I have to use task manager to kill EXCEL process manually.

I have been trying the same solution mentioned in the above link but not successful. Can any body to take the code below to let me know what I am doing wrong?

my app currently has a process thats ongoing (even when I navigate back to the main screen of my app). Is there any code I can use to terminate all the processes on that page before it navigates back to the main screen. In other words the page should reset to its original form?
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Visible = False Me.ShowInTaskbar = False[code].....
Notice: I used "End", to terminate the process.What I want to do is when the last function is called (Delete_AutoReq_PracNo) it terminates the execution of the application.
Reason...I'll schedule this application to ran from MS SQL Server at night. So realistically, doing all the processes I would like it to stop...Is what am doing sufficient to stop the application from running or there is a more robust approach..
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]
I'm having a problem with closing Acrobat. I'm using vb.net to sign a PDF file in running Acrobat. After I'm done I close Acrobat and try to delete the currently signed PDF file, but I get an error message telling me that file is being used by another process. I tried closing and setting to Nothing AcroApp, AcroAVDoc, AcroPDDoc JSO, but still that doesn't work. I tried releasing them with Marshal.ReleaseComObject(...) still no effect.[code]
I am using Process.Start in my application, which is working great.My only problem is, the program it "starts", is an installer, which takes about 5 minutes to install. I woud really like to hide all my forms and only show one that says "please wait", but i cant seem to get it to stay there till the process has finished.
I'm currently practicing working on mobile application using vb .net 2008. So I have these 5 forms that I link together. The form # 2 is where my quit button was positioned. I want to quit the whole application but form # 2 was the only form that is terminated while the rest of the forms was not.
I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.
In certain error situations within my VB 2008 code, I need to quickly terminate the program. This should be simple, but I haven't been able to figure out how to do it.
I'm trying to close down a program from within the constructor for the main form. I've tried Me.Close() but this gives an error: ObjectDisposedException was unhandled. Here's the details:
System.ObjectDisposedException was unhandled Message=Cannot access a disposed object. Object name: 'Form1'.
how about to terminate a tcp connection My program can view all the TCP connections and i want to terminate some connections but i realy don't know how to terminate some connection from another process
I have a website, that needs to not allow simultaneous logins. I am controlling that by cache. But, now I am unable to give them the option to log out the other session. Goal: is to allow them to login, and when they do, tell them that the current user is already logged in, and give them an option to close that session, so they can continue logging into the system (website).Have not found any way to terminate a specific SessionID. oh BTW, I do have the sessionID of the parallel session, just dont know how to kill that one. Again note, I do not want to close this current session, but another session whose SessionID I have.
I am not able to get the exit window button to terminate once I click on it. I am not sure what I am doing wrong. This is the code I am using for it: btnExitWindow.Enabled = True. Everything else is working fine when I run the program.
I want to terminate an application using the full file path via vb.net, so I am using this code snippet.
Public Sub forceCopy() Try 'Dim strDatabasePath As String = My.Computer.FileSystem.CombinePath(Application.UserAppDataPath, "LIC.mdf") Dim strdbLogPath As String = My.Computer.FileSystem.CombinePath(Application.UserAppDataPath, "LIC_log.ldf") [Code] .....
I get an exception "Access Is Denied". I get the error at this line : For Each m As ProcessModule In process.Modules
I am trying to end a program immediately when a critical exception is caught. But I am finding that code after my Try/Catch block is executing even though the code withing the Catch block is executing, and that Catch code is calling Me.Close.
I suspect it has something to do with background .net threads or something, but I have no clue how to deal with those kinds of issues. How can I stop the program as quickly as possible? If code after my Catch executes, it will (and does) throw lots of uncaught exceptions later. Currently, it is not feasible for me to try to catch all the other exceptions. I just want to report an error and end the program.In my form load routine, I create and set up a number of objects and arrays by calling various subroutines.The success of most of the subroutines depends on the sucess of three subs in particular, which are called early on. If one of those three fails, there will undoubtedly be a number of hard to trap exceptions later on in the load routine.
I wrote the following code to build a basic game that makes two cars race (randomgenerator) and let the user pick their bets on the end results. I've gone terribly wrong somewhere in that my cars only race halfway then get stuck behind the start line and the programme keeps repeating the beeping and the messsagebox.show and adding results to the 'incorrect' box.
The only way to terminate the application is to hit 'stop debugging'.
Option Explicit On Option Strict On Public Class MainForm
I have just started a simple project in VB 2008 express (having previous experience (not much though) in VB6). At the moment I have only 1 form and when I click on the red x close button the form closes but the process is still running in task manager. I have the following code which I assumed would exit the program and terminate the process but it doesnt seem to work[code]...
i know this is a big problem for a lot of people and there are posts everywhere..below, should this complete and close and terminate excel correctly? or am i missing something.
