via code you are asking? Not very clear of the case.

Why do you think uninstallation can complete if the process is running? maybe some steps could be done but uninstallation will certainly fail to delete your code...

And, just in case, how about the opposite approach -- uninstaller asks if you "really-really" want to uninstall and terminate the process which prevents uninstallation? It may make sense...

while uninstalling, if the application running. u will get pop up dialog saying
the following app is opened
Cancel Retry Ignore.
If i selected ignore it's continue uninstall but the application which is opened is remained and then i have to close manually.

i can able to kill the process but i want to stop uninstallation.

I would recommend creating a custom action in your setup project to override the OnBeforeUninstall() function, and cancel it in there. Something along these lines:

C#

protected override void OnBeforeUninstall(IDictionary savedState)
{
     base.OnBeforeUninstall(savedState);
     if(Process.GetProcessesByName("nameOfYourProcess").Length > 0)
     {
          throw new InstallException("Cannot uninstall while appname is running.");
     }
}

Thank you very much.
can you explain what is it mean
Process.GetProcessesByName("nameOfYourProcess").Length > 0

JOAT-MON 23-Dec-10 2:21am

Process.GetProcessByName() is a static function that will search the currently running process list for a process with the name you pass to it as a parameter. It returns an array of processes, so if that array is .Length == 0 then the process is not running. However, if the .Length > 0 then the process it was looking for is running.

That is not c# (read the question tags before answering)

JOAT-MON 24-Dec-10 5:35am

@Toli - I did read, but it is my habit to do my custom actions in vb. Answer edited to show the C# translation.

hii got a simple exe with a setup project using c# and studio 2005 ...where do i add your code exactly ??

its not working.i added the code in installer class and then add custom action delete

Here is a link to creating and adding a custom action:

In this walk-through you will add an installer class to the custom action, and it is in that installer class that you want to override the OnBeforeUninstall().

Did you do the walk-through I posted the url to in the above comment?

Sandip Paul 491984 25-Sep-13 5:37am

ya i have done
1> first i include a installer.cs file and add the code
2>next i create a custom on delete
but the problem remains same at its position
