I have a .NET 2005 (C#) desktop application, in which there is a login form and an MDI form, which then have multiple subforms. All other forms are opened in MDI form only.

After a user logs in, I hide the login form and then show the MDI form, but when I close the MDI form, my application process does not end because the login form is still hidden. I want that, when the user closes the MDI form, the whole application should close (essentially, the process should not be shown in the task manager), because if everytime the user closes and reopens the application and logs in, it will create some performance problem.

I am doing something like below:

//my login validation script,

//after successful login

this.Hide();

if (globalData.ObjMdiMain.IsDisposed)
{
    globalData.ObjMdiMain = new mdiMain();
}
globalData.ObjMdiMain.Show();

globalData is my static class where I create global objects which are required by the whole application. There, I have defined the ObjMdiMain object of my MDI form and I am accessing it here in the login form.

So, is there any method or function which will end the whole process from system, something like “Application.End();” or something else?

Thanks!

    It seems a MySql .net connector bug, because I was using mysql .net connector DLL to connect to my mysql db. I have seen some other complains about it too. See
    http://bugs.mysql.com/bug.php?id=36688

    I was using MySQL .net connector DLL of version 5.1, I have just upgraded to 6.1 (latest) and its working fine without any error.

    Download the latest DLL here: http://dev.mysql.com/downloads/connector/net/6.1.html

    Thanks
