. Introduction ClickOnce is a good technology, but in some cases it can be hardly customizable.
Recently I had a requirement for a ClickOnce application to launch on start up. Sounds simple, right? But not for ClickOnce. You can Google and find that it is or was a real problem for some developers.
Any ClickOnce application based on an.exe file can be silently installed and updated by a custom installer. A custom installer can implement custom user experience during installation, including custom dialog boxes for security and maintenance operations. Nov 5, 2007 - In the default ClickOnce behavior, this results in automatic update, instead of being. It was exactly what I hoped Google would help me with. SQLCE version at client PC during Clickone installation programatically.
That launch on start up is not supported by ClickOnce deployment, also it has limitations in Registry access. In this article I will show one of the approaches to solving this issue. It may have some disadvantages, but is reliable and can be used in some apps. Functionality This solution allows you to:. Add a shortcut to your application in the startup group, so it will be launched on startup. Delete shortcut from startup group on uninstall. Clean up whatever you want to clean up on uninstall.
Auto close application on uninstall (actually the process is killed, but you can add some messaging and ask your program to close). Set icon you like in Application Wizard instead of default one.
Set some help and about links for your application in the Application Wizard. Well this is the problem with this approach, actually what it does when you uninstall is starts uninstall.exe which asks user a confirmation and deletes all data from publish folder and itself, and finally ClickOnce uninstaller launched, which shows it's own dialog and the code just presses buttons instead of user to remove it. To change version I think it is better to make a simple updater based on uninstall.exe, so when launched it will ask user if he wants to change the version, fetch available version and uninstall/install.
This can be tricky, but i think doable. Maxime 15-Mar-13 5:26 15-Mar-13 5:26 Hi, I'd like to thank you for your article here, it's very useful for what I'm trying to achieve. However, I'm not entirely sure about two things: 1) Where does the 'UninstallString.bat' file come from? It's not in your downloadable code, nor does it seem to be generated by the project. 2) You reference the 'Unistall.exe' file in your main application, which comes from the Release folder outside your projects' folders.
Is that a copy of the.exe generated by the Uninstall project that has been renamed? As a side note, I'm using Visual Studio 2010, so I can't open your solution per se, so there may be some stuff I missed as I only had access to the source code, not the compiled result. Thanks a lot! Hi, As you already found UninstallString.bat content is taken from registry field.
Regarding 'Uninstall.exe': main project CustomizedClickOnce has build dependencies on CustomizedClickOnce.Common and CustomizedClickOnce.Uninstall projects. So when you build CustomizedClickOnce project, first CustomizedClickOnce.Uninstall will be built and when main project starts to build it has the latest uninstall.exe.

Uninstall.exe has build action Content and is chosen among application files to be included in published delivery. Project dependencies and build order can be changed in context menu for a project.
