Drag-drop executing

I use several programs that are run by dragging an input file on top of the executable. This intrigues me. How is it done? Does it just send the input file''s name to argv? Do you have to add something to the code to make it work, or does it work automatically?

Yep, the filename is just passed into the argument vector.

Well, I have it working now so that it outputs argv. The only problem is, it outputs the entire file name, directory included. Is there a way I can have it cut off the directory? I suppose I could have it just clear out the string every time a \ is detected, but that feels a bit hacked. Is there a better way?

Surely you want the directory? If the user drags a file on their desktop on a shortcut, you''d need the full path to load the file...

Well, I want to create variables and such just based on the file name.

Just snip it off yourself; it''s not that hard. Just cut off everything before the last ''\\'', making sure to snip off the last quotation mark if one exists.

Alternately if you use boost::filesystem, the path class has a leaf() member function that will return the file name without the rest of the directory path as a std::string object.

If you do not mind limiting yourself to windows only you can use PathStripPath().
