I'm trying to implement transparency for the taskbar (Shell_TrayWnd) in Windows, similar to the functionality that TranslucentTB has. However, in my implementation, the problem is that elements such as the Start button, search box, and attached programs also become transparent, which is not what I expected.

Used Win32 API functions such as SetWindowLong, SetLayeredWindowAttributes to set transparency. It made every element of Taskbar transparent.
