谁能给一个C++编弹窗的程序代码？最一般的弹窗即可，要后边带注释的哦，谢谢

#include

// Global variable

HINSTANCE hinst;

// Function prototypes.

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int);

if (!InitInstance(hinstance, nCmdShow))
return FALSE;

while ((fGotMessage = GetMessage(&msg, (HWND) NULL, 0, 0)) != 0 && fGotMessage != -1)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
UNREFERENCED_PARAMETER(lpCmdLine);
}

BOOL InitApplication(HINSTANCE hinstance)
{
WNDCLASSEX wcx;

// Fill in the window class structure with parameters
// that describe the main window.

wcx.cbSize = sizeof(wcx); // size of structure
wcx.style = CS_HREDRAW |

wcx.lpfnWndProc = MainWndProc; // points to window procedure
wcx.cbClsExtra = 0; // no extra class memory

wcx.hIcon = LoadIcon(NULL,

wcx.hCursor = LoadCursor(NULL,

return RegisterClassEx(&wcx);
}

BOOL InitInstance(HINSTANCE hinstance, int nCmdShow)

// Save the application-instance handle.

// Create the main window.

return FALSE;

// Show the window and send a WM_PAINT message to the window

UpdateWindow(hwnd);
return TRUE;

}
以上是MSDN中的例子，很详细了。

在VC下建一个基于对话框的工程 直接运行就是个对话框呢
如果是想点击按钮弹窗的话，先拖个按钮控件，然后添加消息函数。
函数代码：
void CTestDlgDlg::OnButton1()
{
// TODO: Add your control notification handler code here
MessageBox("Button1 has been pressed!");
}
你点击按钮就会弹出窗口了，窗口内容为：Button1 has been pressed!
