你說(shuō)的是控件中的字對(duì)齊嗎?
字對(duì)齊是改變控件的TextAlign屬性,該屬性一共有9個(gè)屬性值,
TopLeft,TopCenter,TopRight,MiddleLeft,MiddleCenter,MiddleRight,BottomLeft,BottomCente,BottomRight,分別對(duì)應(yīng):上左;上中;上右;中左;正中;中右;下左;下中;下右;
如果你說(shuō)的是控件對(duì)齊窗體的話,那么直接修改控件的Location屬性就可以了。比如一個(gè)按鈕控件實(shí)例btn需要位于窗體正中,那么,代碼應(yīng)該寫成:
Dim x, y As Integer
x = (Me.Width - btn.Width) / 2
y = (Me.Height - btn.Height) / 2
btn.Location = New System.Drawing.Point(x, y)
'新建一個(gè)VB.NET 項(xiàng)目,把原來(lái)所有代碼刪了,把下面的代碼復(fù)制貼上去解OK了
