It's quite possible. Just use CFileDialog and CPrintDialog.

I need to know what the actual code has to be.  Because I am not familiar with that function.

bOpenFileDialog   Set to TRUE to construct a File Open dialog box or FALSE to construct a File Save As dialog box.

A simple example, usable, but not very sophisticated:

      HANDLE      FileHandle;
      BYTE*      pBytes;
      CString      FileName;

Now open a FileDialog for "Save As" (1st parameter FALSE)

      CFileDialog FileDialog( FALSE, ".bmp", NULL, NULL,
                        "Bitmap Files (*.bmp)|*.bmp||",
                        NULL );

      if (FileDialog.DoModal() != IDOK) return; // means User pressed "Cancel"

      FileName = FileDialog.GetPathName();

Now you've got your Filename; open the file and get a handle to it.

      FileHandle = CreateFile(FileName,
                        GENERIC_READ | GENERIC_WRITE,
                        (DWORD) 0,
                        (LPSECURITY_ATTRIBUTES) NULL,
                        CREATE_ALWAYS,
                        FILE_ATTRIBUTE_NORMAL,
                        (HANDLE) NULL );

      if (FileHandle == INVALID_HANDLE_VALUE)
      {
            MessageBox("Failed to create file!", "OK", MB_OK);
            return;
      }

Now write your data.

Less than excellent, but thank you anyway. Maybe you should take a look at the documentation for CFileDialog, and its member variables (m_ofn, especially), for a more failsafe and detailed approach.

To save data into the file that is created would I just use the serialize command and then the IOstoring command or is there a better/ easier why to do it.

Depends on the kind of data you want to write to your file. Given the FileHandle as in the example above, you might just use WriteFile(FileHandle, etc.). Seems the easiest approach to me if you write e.g. a Bitmap-File.

I am saving text and numbers to the file.  What should I do in your opinion.

I'm really not familiar with serialization, I haven't used it up to now. In my therefore not very expert opinion, it seems a good method for storing objects in a file.
What you seem to be about to do is just store plain data, using your own file format. So, if you're sure about your format (e.g., how will your program know what kind of data is where when it attempts to read the file?), I would probably write it as plain data 'as is'.
I'd recommend to seriously consider the possible variations of reading that file again before deciding how to write it. The data amount shoud be one topic of your considerations, as well as possible write or read errors and how to handle them.
But I'm afraid I can't even guess what could be the best way for you before knowing a few details about your program.
