Hi. You could use the Windows registry. Cheers.

Hi, 1. If variable is required before starting another exe then pass that variable as command line. 2. If you want to pass variable after starting another exe then use Inter Process Communication such as WM_COPYDATA, Pipes and Shared Memory. Amar:)

good software design should not include registry as active place for data share between two application

they are one of best IPC mechanism, but i recommend you discourage use of PIPe.. Window message is also good option
