This post pertains to using the Chilkat Self-Extracting EXE utility. The goal is to create a self-extracting EXE such that the files are unzipped into the directory where the EXE is located. To do this, the %CD% environment variable is used in a DOS command line. The intent is to use the -d option with “%CD%” so that the environment […]

Answer: For objects that manage a TCP/IP socket […]

If you search the Internet, […]
