To say I have two independent projects, one is the system interface software, a software is receiving data, I want to click a button to open in the system interface receives the data of the software, and the receiving complete system again after the download is complete shown on the interface, online while you can see in the system interface software button with Winexec or ShellExecuteEx opened the receiving software, but don't know how to receive software interface to the system after the download is complete a return value, used to perform the download is complete, should be displayed in the system interface the download is complete,
Another way is to merge, but don't know the specific how to operate, is to put the Source Files, Header Files, Resource Files Files are added to the interface software code? I am a novice, please advice,
