( ycguo 发表于 2006-11-3 12:46:00)
SC_DEFAULT Selects the default item; the user double-clicked the window menu.
SC_HOTKEY Activates the window associated with the application-specified hot key. The low-order word of lParam identifies the window to activate.
SC_HSCROLL Scrolls horizontally.
SC_KEYMENU Retrieves the window menu as a result of a keystroke.
SC_MAXIMIZE Maximizes the window.
SC_MINIMIZE Minimizes the window.

Parameters
uCmdType
Specifies the type of system command requested. This parameter can be one of the following values. Value Meaning
SC_CLOSE Closes the window.
SC_CONTEXTHELP Changes the cursor to a question mark with a pointer. If the user then clicks a control in the dialog box, the control receives a WM_HELP message.
( ycguo 发表于 2006-11-3 12:46:00)
xPos
Specifies the horizontal position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. Otherwise, the xPos parameter is not used.
yPos
Specifies the vertical position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. This parameter is –1 if the command is chosen using a system accelerator, or zero if using a mnenomic.

MSDN中关于SC_RESTORE消息的解释，参考：
WM_SYSCOMMAND
A window receives this message when the user chooses a command from the window menu (formerly known as the system or control menu) or when the user chooses the maximize button, minimize button, restore button, or close button.
WM_SYSCOMMAND
uCmdType = wParam; // type of system command requested
xPos = LOWORD(lParam); // horizontal position, in screen coordinates
yPos = HIWORD(lParam); // vertical position, in screen coordinates

只是解决了如何拖动对话框，但是发现有好多人的确不知道到底是怎么实现的。
我的代码，供参考：
void CLogonFrm::OnMouseMove(UINT nFlags, CPoint point)
{
//在WM_MOVE消息处理函数中通过向自己发送参数
//wParam为HTCAPTION
//lParam为鼠标位置的WM_NCLBUTTONDOWN消息
//实现窗口移动
//此时窗口移动过程的绘制由系统实现。
if(MK_LBUTTON & nFlags) //如果按下了鼠标左键
{
SendMessage(WM_NCLBUTTONDOWN,HTCAPTION,(LPARAM)(point.x|(point.y>>16)));
}
CDialog::OnMouseMove(nFlags, point);
} ( ycguo 发表于 2006-11-3 12:40:00)
