Hi All,

Can anyone tell me how to change the value of an Environment variable programmatically? I have tried _putenv, _wputenv and SetEnvironmentVariable. All of them are returning success but the value is not changing.

Can anyone tell me where I am going wrong?

Thanks and Regards,
Anil

The environment block for each process is a copy of the system environment. You can modify it for your own process. But you cannot change the environment for other applications.

i have to admit that his answer was more clear, so i think it does not qualify as spam.

Is that necessarily a bad thing? Are you sure that he saw your post before making one of his own?

if the frame is Modal, then it halts the execution of the function which called it, unless it is closed from inside it.

inside the frame, do this->EndDialog(0);

As has already been mentioned, EndDialog() is the answer, but I would suggest using some argument other than 0 (which normally indicates success) to indicate to the calling process why the application was terminated.

How do you propose using GetSystemMetrics() to get the "physic memory size and information of chassis" as the OP has requested?

I don't think you can do it.

Of course you can hide the folder but for making it inaccessible to be edited or viewed I don't think there is an API for that.

Are you wanting to do this programmatically, or use the OS to do it for you?
