}程序有一个错误就是找不出来

Answer 1

没办法看,有个头文件内容没贴出来,你到底报什么错啊?
我用了一下你的代码,好像在int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR　lpCmdLine,int nCmdShow)有个非法字符,应该是LPSTR后面的空格有问题,但是不知道是不是这个网面的问题

Answer 2

楼上的这个空格的问题找出来了，但还有一个错误提示：
F:\工作区\Scrllbar\Scrllbar.cpp(35) : error C2440: '=' : cannot convert from 'void *' to 'struct HBRUSH__ *'
        Conversion from 'void*' to pointer to non-'void' requires an explicit cast

Answer 3

现在编译已经通过了，但是连接的时候有出现错误：
