How can these be done. For example running a shourtcut thats path is this

C:\app.exe -sync

will run a certain part of the application(the sync function). Do i need to make a seperate application. Also say i have a program that plays music files. then i have a music file that i right click and select to open with ,my proggie. How could i make it so that it knows to play that file?

i hope thats clear. The main thing i would like to know is the command line arguments.

Helpful clarification and practical steps following the suggestions from , and .

Important detail: the argument array that the Main entry point receives is the list of user-supplied tokens only; the raw command-line array available from the environment includes the executable path as element zero. That difference changes index offsets when code expects "first argument" vs. "executable name + args".

Windows behavior and shortcuts: Explorer passes the selected filename as a quoted command-line argument when using "Open with" or when a file association is registered. For permanent associations the shell open command must include the placeholder "%1" (use "%*" to accept multiple selected files). For shortcuts, the Target should contain the quoted application path (if it has spaces) followed by any switches and then the file placeholder; otherwise the shell will split incorrectly.

Parsing and robustness: do not rely on fixed positions. Treat tokens that begin with '-' or '/' as switches and treat other tokens as filenames; strip surrounding quotes before using paths; accept both single and multiple file inputs and validate each path exists before attempting playback. For debugging, log the exact argument list the process receives when launched from Explorer, a shortcut, and from the command prompt to confirm what is actually being passed.

Safety and tooling: validate and sanitize all incoming paths, handle exceptions gracefully, and avoid executing anything based solely on an unvalidated argument. For more complex option sets, prefer a small option-parsing library rather than ad hoc string splitting. These points extend the earlier replies and address the practical issues needed to implement a -sync switch and an "open with" file-playback scenario.

make your Main look like this and "args" is a string array of all the args passed
