C# SetEnvironmentVariable

[Kir Birger]

Is there some trick to using this method? I looked up code samples and they are all just one line: Environment.SetEnvironmentVariable(strName, strValue); Yet when I do it, nothing is changed... I'm trying to modify the PATH variable by the way

It's integrated into VS2005, but I tried that anyway=). importing that is the same as doing Environment.SetEnviornmentVariable()

[Kir Birger]

Very odd... Doing that I get an error on this line: envObject["PATH"] = sPath; Error reads: Unable to cast COM object of type 'System.Management.WbemDefPath' to interface type 'System.Management.IWmiSec'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2FD73A3B-64B3-480D-AEE9-54469D77123E}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

You realise the values will only be changed within your current process? And will not be persisted?

Then how do i Change the actual values? I've also tried changing them via registry and making a sendmessage call to 'update' them, but it didn't work.

I've tried a few variations of that SendMessage attempt...
