Change environment variable in console process ...

Hi ...

I have read many articles that describe the process to update environment variables in another process. As I understand I should be able to change the either of the regsitry values below ...

HKEY_CURRENT_USER\Environment
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment";

and then call SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0) tp propagate these setting to other applications.

When I do this I do not see the environment variables in my current console process change when I use SET to display the environment variables in the console.

?? Why don't I see the change in the console ??

Below is some code / Details:

- I open a command prompt using Windows XP.

- Use SET to view environment variables (MXBUILD_VERSION) is not present.

- Start a command file that gets files from SourceSafe and then calls a program called ManageVersion.

- ManageVersion will update the version info in the version.h file and then save the version info to an enviroment variable called MXBUILD_VERSION. I have sent this in both the User and System Regsitry in an attempt to propogate the value to the console enviroment. After the registry is update dhten I call the SendMessage() method.

Code:

// We tryed both methods nReturn = SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM) "Environment", SMTO_ABORTIFHUNG, 5000, &dwReturnValue); nReturn = SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);

Thanks,
