给窗口起名为AboutBox，源文件命名为AboutBox.Cpp
选Project->Options，将新建的窗口从自动建立中去掉。
选View->Project Source，打开工程文件的源文件，在下面加入句子。

#include "AboutBox.h"
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
DWORD lTime;
try
{
Application->Initialize();
AboutBox=new TAboutBox(AboutBox);
AboutBox->Show();
AboutBox->Update();
lTime=GetTickCount();
Application->CreateForm(__classid(TMainForm), &MainForm);
while((GetTickCount()-lTime) / 1000 <3);
AboutBox->Hide();
AboutBox->Free();
Application->Run();
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
return 0;
}
