There’s a part in my apps that displays the file path loaded by the user through OpenFileDialog. It’s taking up too much space to display the whole path, but I don’t want to display only the filename as it might be ambiguous. So I would prefer to show the file path relative to the assembly/exe directory.
For example, the assembly resides at C:\Program Files\Dummy Folder\MyProgram and the file at C:\Program Files\Dummy Folder\MyProgram\Data\datafile1.dat then I would like it to show .\Data\datafile1.dat. If the file is in C:\Program Files\Dummy Folder\datafile1.dat, then I would want ..\datafile1.dat. But if the file is at the root directory or 1 directory below root, then display the full path.
What solution would you recommend? Regex?
Basically I want to display useful file path info without taking too much screen space.
EDIT: Just to clarify a little bit more. The purpose of this solution is to help user or myself knowing which file did I loaded last and roughly from which directory was it from. I’m using a readonly textbox to display the path. Most of the time, the file path is much longer than the display space of the textbox. The path is supposed to be informative but not important enough as to take up more screen space.
Alex Brault comment was good, so is Jonathan Leffler. The Win32 function provided by DavidK only help with part of the problem, not the whole of it, but thanks anyway. As for James Newton-King solution, I’ll give it a try later when I’m free.
