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 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 must change the SessionID for an ASP.NET 4.0 Application (SessionID via Cookies) to have it run on 2 domains with the same Session [URL]... This will keep the Items in sync abov the 2 domains.
Therefor the Page will have iframes with an "setkey.aspx/ashx", which must set the new SessionID.
Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option)
All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.
I've been trying to find a way to determine if I need to launch an application or maximize it because it is already running for the current user. The problem I am running in to is since I'm using the For Each command the application though it now knows to open the external .exe wants to open multiple since more than one instance of the application is running without the same SessionID.
VB.NET Private Sub OrderLaunchOrSwitch() Dim CurrentSessionID As Integer = Process.GetCurrentProcess.SessionId Dim hwnd As IntPtr
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.
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 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 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 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'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 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.
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?

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 want to terminate an application using the full file path via vb.net, yet I could not find it under Process. I was hoping for an easy Process.Stop(filepath), like with Process.Start,
