Implement the basic class cbitmapsk for skin replacement of Wince software in EVC

since hook is not supported under wince, therefore, it is very helpful to change the software of Ce. However, I have seen a foreign website with the Code I didn't understand it. Oh, I am too watery. This involves another problem. I haven't found a method to implement hook. I have to find another method, therefore, you should rewrite the control in any case. Refer to the skin replacement implemented by some VC and implement the basic class cbitmapsk here. One of the depressing points is that EVC does not fully support crgn, And it is troublesome to implement windows of any shape. Therefore, an important function cannot be implemented. If you want to implement other functions,

We haven't found any third-party controls under CE. We have seen the best ccebutton, which was developed under evc3.0...
