Problem Copying File From CD

[ipointer]

I am an experienced programmer that is fairly new to C++. I have written a small installation executable that is supposed to copy a set of files from within a directory just on the CD. The problem is that I do not know which drive letter will be used for the CD (EG D:\, E:\ F:\). I have tried copying the file using windows.h and system("COPY .... "); both look for the files in my documents, not on the CD...

Example code:

CopyFile("bin\\install.php", copyfile.c_str(), true);

- OR -

cmd = "COPY /Y \"bin\\install.php\" \"" + htdocsloc + "\\install.php\"";
cout << cmd << endl;
system(cmd.c_str());

When compiled, then the exe put on the cd, it says that the system cannot find the file specified. Can anyone help me with this problem?

If this is Windows you can call GetCurrentDirectory() and fish the drive letter out of the returned string.

Great, I will give it a try and reply back if it worked. Thank you very much.

You can also get drive letter determination for Windows:
