How to Add Custom Action to Visual Studio Setup Project

2011-09-20T22:49:00.001+06:00

Creating simple setup project in visual studio is very easy. Sometimes we need to perform some custom action at the time of install/uninstall such as start a web page. Today i will show you how you can add custom action in your Winform application. I will use C# as language.

First create a WindowsFormApplication. Then create a Setup Project from File->Add->New Project. Follow Other Project Types -> Setup and Deployment -> Visual Studion Installer -> Setup Project. Name it Setup1.

Now go to your Winform Project and add a installer class. Name it Installer1.cs. Open it as Code View. Here you can override four important functions, Install, Commit, Rollback and Uninstall. You can guess their functionality from name.

Suppose we want to open a web page before stating uninstallation. Add the following code:

[System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Demand)]
public override void Uninstall(IDictionary savedState)
{
    System.Diagnostics.Process.Start("http://www.microsoft.com");
    base.Uninstall(savedState);
}

base.Uninstall will start actuall uninstalltion. If you want the same functionality before starting installation you can add the following code:

[System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Demand)]
public override void Install(IDictionary savedState)
{
     System.Diagnostics.Process.Start("http://www.microsoft.com");
     base.Install(savedState);
}

Commit will fire after completing install transaction and Rollback when installer restores the pre-installation state of the computer.

Right click on Setup1 and go View->Add-> Project Output. Select WindowsFormApplication from project dropdown, select Primary Output and click OK.

Now we have to add the Installer1.cs to the Setup Project. Write click on Setup1 and go View->Custom Actions. We override only the Uninstall function. So, right click on Uninstall and click Add Custom Action. Go Application Folder -> Primary Output From... then click OK. Build Setup1, install it and uninstall to check the functionality.

Windows 8 Developer Preview

2011-09-19T21:45:00.004+06:00

Microsoft released Windows 8 Developer Preview last week. You can download 32-bit and 64-bit of Windows 8 directly. The developer tool version requires clean installation. But you can upgrade existing Windows Vista and 7 keeping all accounts, files and settings. For XP you can keep accounts and files but not settings. I personally recommend clean installation.

System Requirements

Windows Developer Preview works great on the same hardware that powers Windows Vista and Windows 7:

1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver
Taking advantage of touch input requires a screen that supports multi-touch
To run Metro style Apps, you need a screen resolution of 1024 X 768 or greater
