Check out CodeProject code section for examples of object-oriented designs.

Think of an object as a person, place, or thing that represents what a system needs to know and do about an actual person, place, or thing. Think of an object in first-person form. Instead of saying "How can it do ____ to that object?", say "I am a ____. I know hot to ____ myself." instead. When you can look at an object in this fashion, the laying out of objects and the relationship(s) between objects becomes clearer. Something that I learned in undergraduate school was that of "strong cohesion, weak coupling." While it was not discussed in the context of OOP, it still applies.

Getting 'MFCs' current directory

Hi all, im sure this will be an easy question for some of you but i have failed to find an answer after searching through previous posts.

When i open a CFileDialog in my app the directory it starts in is different to the return value of GetCurrentDirectory() (and _getcwd). How do i get the directory that a CFileDialog would point to if i were to open it?

Cheers for any help,

Andy.

Cheers for the reply but no. I dont want to set the initial directory of the CFileDialog. I want to get the directory that a filedialog will point to if i were to use it. This directory may be different to the current working directory. MFC must be storing this somewhere in the registry based on the app name but i'll be buggered if i know where.

Cheers anyway.

Andy.

Have you looked at the documentation for the lpstrInitialDir member of the OPENFILENAME structure? I'm pretty sure that it details what Windows will use as the directory when one is (not) specified.

One solution is CFileDialog's GetPathName() member function.

Cheers for the reply.

I tried that but i dont want to have to store this value anywhere and i cant guarantee a file open dialog being used before displaying my folder open dialog (which is the thing i want to point to the same location).

Any other ideas?

Okay.

Your original question was not very clear. Do you want to get the full path of the file that a user had selected via CFileDialog? Do you want to set the directory where CFileDialog first starts out?

I want to get the directory that a CFileDialog choses as its initial directory if the lpstrInitialDir of the OPENFILENAME structure is left empty.
There is an algorithm it uses to choose this directory (as explained in the OPENFILENAME documentation) but i want to be able to call a function (on something) to get me this directory without having to replicate this algorithm myself.

So i dont want to do either of what you suggested.

Cheers for your help.

Andy.
