You can use SHFileOperation[^].

RemoveDirectory() only deletes empty directories. To delete files and folders simultaneously, use SHFileOperation().

You may use CBitmap::GetBitmapBits [^].

You may use CImage class for the purpose, see CImage::Load [^] and, for instance, CImage::GetPixel [^].

Just in addition to CPallini's post.

If you decide to use CImage class you will notice that the GetPixel and SetPixel methods are slow. So if you need a fast pixel access you can use this[^] class with combination of CImage class.

Using CxImage[^] library could also be an option. Smile | :)

Just make sure you include <windows.h> (in example you can include it in stdafx.h, if you are using precompiled headers) before the include of zip.h and the errors must gone. Smile | :)
