Is there any way to judge is by user double-click to open notepad, or point of TXT file open?-CodePudding

As title, also have no a clue, do you have any good idea, thank you

CodePudding user response:

Know this have what use, some TXT open when parameters have a file name

CodePudding user response:

Access to the command line parameters, double-click the TXT file name parameters.
Shortcut to open no parameters

CodePudding user response:

If it is after. Double-click to open a TXT file to load. It is impossible to check out.

CodePudding user response:

By comparing the work directory and exe path, and can judge: not consistent, it must be opened by TXT, consistent by open notepad exe

The key is how do I get other command line arguments of the program, thank you

CodePudding user response:

refer to the second floor wr960204 response:

command line parameters, double-click the TXT file name parameter.
Shortcut to open the no parameter

The key is how do I get other command line arguments of the program, master give some train of thought, thank you

This function can get the other processes of command line arguments

Good idea
