C # Use The Sohu Weibo api to remotely change the wallpaper

Through Sohu Weibo's api, http basic authentication is used, and Sina's oauth must also pass browser authentication, which is too troublesome. The entire program is divided into several small parts, not difficult.

Implement the following functions:

1. Start the instance. If the program runs, the C: gimg folder is created, and the program itself is copied to the folder. The program in this folder will be used when it is started. The downloaded wallpaper is also in this folder.

2. automatically update the wallpaper.

3. Get the image link from Sohu Weibo and download the image.

4. md5 verification, used to compare whether the current wallpaper is the same as the downloaded wallpaper.

5. Hide the window and run it in the background without dropping the window.

6. Convert the image format. In the XP system, call SystemParametersInfo to change the wallpaper. Only the bmp format is supported. Note that the uploaded image is also in bmp format.

The C #. net class encapsulated by Sohu Weibo is used in the code, which is easy to use. This class Library:
