Hi,

I am creating a Setup.exe file using setup and deployment project for my C#.NET application. While Installing I need to check a folder in C: drive and if it exists, I need to delete the folder. How to do such custom actions while installing?

Sanjeevi

Hi,

You can use custom actions to run code at the end of a Windows Installer installation to perform actions that cannot be handled during installation. (From http://msdn.microsoft.com/en-us/library/d9k65z2d.aspx )

By the way, do you mean you want to check whether installation folder exists? You can select a folder in select installation folder form.

Best regards,

Ling Wang

Hi Ling Wang,

Thanks for the reply! After a long time, I could see some response here.

I gone through that link. I have also gone through some of the aricles available in web. But I coul'nt do any custom actions while installing.

Please see the code snippet of the installer class.

using

System;

using

System.Collections.Generic;

using

System.Text;

using

System.ComponentModel;

using

System.Configuration.Install;

using

System.Collections;

using

System.IO;

using

System.Diagnostics;

namespace

SynapseInstallerClassLibrary

{

[

RunInstaller(true)]

public partial class Installer1 : Installer

{

public Installer1()

{

InitializeComponent();

this.Committed += new InstallEventHandler(Installer1_Committed);

}

public override void Install(IDictionary stateSaver)

{

base.Install(stateSaver);

}

public override void Rollback(IDictionary savedState)

{

base.Rollback(savedState);

}

public override void Commit(IDictionary savedState)

{

base.Commit(savedState);

}

public override void Uninstall(IDictionary savedState)

{

base.Uninstall(savedState);

}

private void Installer1_Committed(object sender,

InstallEventArgs e)

{

string strPath = "C:\\Program Files\\Sanjeevi";

try

{

if (Directory.Exists(strPath))

{

Directory.Delete(strPath);

}

}

catch (Exception)

{

throw;

}

}

}

}

Depends what you mean by "while installing". If you want to delete that folder before anything is copied you're not going to be able to do that with a custom action because they run after the install, after your files have been installed.
