Visual Studio 2010 SDL_Event errors

我正试图用Visual Studio 2010创建一个SDL游戏，但在构建项目时遇到了很多编译错误。我遵循了本教程来设置Visual Studio，并且我遵循了SDL的本教程。给我这些错误的两部分代码是我的CApp_OnEvent和CApp文件。

CApp_OnEvent:

#include "CApp.h"
void CApp::OnEvent(SDL_EVENT* Event) {
}

CApp:

#include "CApp.h"
CApp::CApp() {
Running = true;
}
int CApp::OnExecute() {
if(OnInit() == false) {
    return -1;
}
SDL_EVENT Event;
while(Running) {
    while(SDL_PollEvent(&Event)) {
        OnEvent(&Event);
    }
    OnLoop();
    OnRender();
}
OnCleanup();
return 0;
}
int main(int argc, char* argv[]) {
CApp theApp;
return theApp.OnExecute();
}

以下是我尝试构建Visual Studio时的输出：
