In the previous MFC video, we used a pre-built dialog. Now we create a dialog of our own. We use an editor (within Visual Studio) to create the look and feel of our dialog and them create a Class to run it.
We also make the images in our document more flexible yet run into issues on that front - issues that will be resolved in the next video.
