如何为线程添加自定义消息映射

Question

我也知道啊 关键是怎么实现
给点样例代码

Answer 1

线程消息循环的简单例子
#include <stdio.h>
#include <windows.h>DWORD WINAPI ThreadProc(LPVOID lpParameter)
{
    BOOL bRet;
    MSG msg;
    while((bRet=GetMessage(&msg,NULL,0,0))!=0)   
    {   
        if(bRet==-1)   
        {   
            //handle the error and possibly exit 
            printf("错误\n");
            return 0;   
        }   
        else   
        {
            switch(msg.message)
            {
            case WM_CHAR:
                printf("asdsad\n");
                break;
            case WM_QUIT:
                return 0;
            }
        }
    }
    return 0;
}int main()
{
    DWORD TId;
    HANDLE h=CreateThread(NULL,0,ThreadProc,NULL,0,&TId);
    Sleep(50);
    PostThreadMessage(TId,WM_CHAR,0,0);
    WaitForSingleObject(h,INFINITE);
    return 0;
}
