雕塑英语蜥蜴:请问VC++如何编写代码使系统在form运行之前自动弹出一个对话窗口？

在FORM的构造函数里放，如：
public ref class Form1 : public System::Windows::Forms::Form
{
public:
Form1(void)
{
InitializeComponent();
System::Windows::Forms::MessageBox::Show("Hello");
}

#include "MyDlg.h"
class CTestsplashApp : public CWinApp
{
public:
virtual BOOL PreTranslateMessage(MSG* pMsg);
CTestsplashApp();
MyDlg dlg;
.
.
.
.
.
.
.
.
}

BOOL CTestsplashApp::InitInstance()
{
// CG: The following block was added by the Splash Screen component.

int tt=dlg.DoModal();
if(tt!=IDOK)
return FALSE;
.
.
.
.
.
.
.
.
.

}
