本文教你如何为程序增加启动对话框和自动弹出IE转向你希望打开的网址。

两个API：

int MessageBox
(
    HWND hWnd, // handle of owner window
    LPCTSTR lpText, // address of text in message box
    LPCTSTR lpCaption, // address of title of message box 
    UINT uType  // style of message box
);

HINSTANCE ShellExecute
(
    HWND hwnd, // handle to parent window
    LPCTSTR lpOperation, // pointer to string that specifies operation to perform
    LPCTSTR lpFile, // pointer to filename or folder name string
    LPCTSTR lpParameters, // pointer to string that specifies executable-file parameters
    LPCTSTR lpDirectory, // pointer to string that specifies default directory
    INT nShowCmd  // whether file is shown when opened
);

补丁代码地址：00405c00

最后修改程序入口为：00405c00

OK！收工！
