Hi,

i have a problem writing to the registry. This is my code:

 

    Dim key As Microsoft.Win32.RegistryKey
    key = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE\codelab3\thumbnailPhoto")
    key.SetValue("MyRegKeyValue", "1234567890")
    key.Close()

 

But i always get the error "The parameter is incorrect". Whats wrong in my code?

Best regards,
Yavuz B.

I think you are missing openSubkey and also writing to system registry require administrative priviledge.

 Dim key As Microsoft.Win32.RegistryKey
    key = Microsoft.Win32.Registry.LocalMachine.CreateSubKey("SOFTWARE\codelab3\thumbnailPhoto")
 **   key.OpenSubKey("SOFTWARE\codelab3\thumbnailPhoto",True)
**    key.SetValue("MyRegKeyValue", "1234567890")
    key.Close()

There are many ways to do this

1) Right click your program executable and click Run As Administrator

2) Do it programmatically, you have to set your program to run as admin during installation http://stackoverflow.com/questions/2313045/how-to-set-run-this-program-as-an-administrator-programatically

3) Embed UAC in your program http://www.professionalvisualstudio.com/blog/2007/10/05/enabling-your-application-for-uac-on-vista/
