In the previous article, we briefly introduced the basic information, parameter descriptions, and functions of flexigrid, as well as the modified style, this article will introduce how to extend the flexigrid function and fix some bugs. In order to facilitate the comparison, I also made a demo for the original flexigrid and provided four application modifications.CodeFlexigrid demo for your reference. I hope this article will help you.

During this time, I developed an image recognition project based on wince6.0 + 6410, using the Development Board of youjian hengtian. This development board has an ov9650 camera connection port, but one of the biggest problems is that the image obtained by the camera is too small and only 320*240 images can be seen. I need 1280*1024 images, therefore, it can only be modified. If you want the driver to provide an interf
