How can I write a registry key from VS post build event?

Question

One of the projects I work on need to read a registry key in order to determine some value. Usually the value will be written during installation.

Because I want to run the project locally as well (without installation) I want to write that value after the build has finished.

Is there a simple way I can do that?

Answer 1

You can create a small program that creates your registry key and call that program in the post build event.

Edit
If you can extract your registry settings to a file, you can add this to you post build event:
regedit /s $(ProjectDir)test.reg

/s makes it silent.

Answer 2

Searching the web I've found this cool tool that comes with windows called REG.EXE

Using it from within VS is simple - REG ADD HKLM\SOFTWARE\\ /v NUnitDir /t REG_SZ /d /f
