C# FindWindow MoveWindow

利用FindWindow MoveWindow 與虛擬鍵盤 達到自動搜尋　另　SetWindowPos

改變窗口的大小和位置(关于MoveWindow()或SetWindowPos())

SetWindowPos()函數使用更靈活，多用於只修改控件位置而大小不變或只修改大小而位置不變的情況：
BOOL SetWindowPos(const CWnd* pWndInsertAfter,int x,int y,int cx,int cy,UINT nFlags); 
第一個參數我不會用，一般設為NULL; 
x、y控件位置；cx、cy控件寬度和高度；
nFlags常用取值：
SWP_NOZORDER：忽略第一個參數；
SWP_NOMOVE：忽略x、y，維持位置不變；
SWP_NOSIZE：忽略cx、cy，維持大小不變；
例：
CWnd *pWnd; 
pWnd = GetDlgItem( IDC_BUTTON1 ); //獲取控件指針，IDC_BUTTON1為控件ID號
pWnd->SetWindowPos( NULL,50,80 ,0,0,SWP_NOZORDER | SWP_NOSIZE ); //把按鈕移到窗口的(50,80)處
pWnd = GetDlgItem( IDC_EDIT1 ); 
pWnd->SetWindowPos( NULL,0,0,100,80,SWP_NOZORDER | SWP_NOMOVE ); / /把編輯控件的大小設為(100,80)，位置不變
pWnd = GetDlgItem( IDC_EDIT1 ); 
pWnd->SetWindowPos( NULL,0,0,100,80,SWP_NOZORDER ); //編輯控件的大小和位置都改變
