是拖动dialog

[a220315410]

dialog和window有区别嘛？

POINT oldPoint;
......
case WM_LBUTTONDOWN:
		{
			if(wParam == MK_LBUTTON)
			{
				oldPoint_Can.x = LOWORD(lParam);
				oldPoint_Can.y = HIWORD(lParam);
			}
		}
		break;
	case WM_LBUTTONUP:
		{
			if(wParam == MK_LBUTTON)
			{
				oldPoint_Can.x = 0;
				oldPoint_Can.y = 0;
			}
		}
		break;
	case WM_MOUSEMOVE:
		{
			if(wParam == MK_LBUTTON)
			{
				RECT rc;
				GetWindowRect(hWnd,&rc);
				SetWindowPos(hWnd,NULL,
					rc.left + LOWORD(lParam) - oldPoint_Can.x,
					rc.top + HIWORD(lParam) - oldPoint_Can.y,
					NULL,NULL,SWP_NOZORDER|SWP_NOSIZE|SWP_NOACTIVATE);
			}
		}

获取鼠标移动的事件，得到一个x，y坐标，然后调用MoveWindow函数或者SetWindowPos函数来进行设置
当然，你还要获取一下你本身的对话框的一个大小，免得大小发生改变

[菜鸟二号]

获取Dialog句柄hDlg;
OnLButtonDown(...)
{
...
SendMessage(hDlg,WM_SYSTEMCOMMAND,61458,0);
...
}

什么叫dialog拖动事件

[yanganglove]

由于楼主题目有歧义，故写上两种：
1,无标题对话框的拖动：

OnLButtonDown中PostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x, point.y));
2,WM_DROPFILE消息：

int nFileCount=DragQueryFile(hDropInfo,0xFFFFFFFF,NULL,0);
int nIndex=0;
while(nFileCount--)
{
TCHAR szFilePath[MAX_PATH];
memset(szFilePath,0,MAX_PATH*sizeof(TCHAR));
DragQueryFile(hDropInfo,nIndex++,szFilePath,MAX_PATH);
........
//处理szFilePath

}
