Question

VB的text内的文字如何上下左右都居中啊

Answer 1

在Vb中如text和label控件是没有垂直居中功能的。
但是可以变通就是给文字加空行。
下面的是从百度贴吧上面引用来的：

但是他并没有说明要将text的mutiline属性设置为true，否则是不行的。

'加一个 Text1 一个 Command1

Dim aa As String, i As Integer, jj As Integer, maxline As Integer, LineCnt As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const EM_GETLINECOUNT = &HBA

Private Sub Form_Load()
'窗体与Command1居中
Me.Move (Screen.Width - Me.Width) \ 2, (Screen.Height - Me.Height) \ 2
Command1.Move (Me.Width - Command1.Width) \ 2, Text1.Height + Text1.Top + 200
Command1.Caption = "居中显示"
Text1.Alignment = 2 'TextBox 水平居中显示
aa = "Attn:楼主"
aa = aa & Chr(13) & Chr(10)
aa = aa & "呵呵你的问题都好奇怪,但也让我学了不少!"
aa = aa & Chr(13) & Chr(10)
aa = aa & "我也想不出其它的好方法"
aa = aa & Chr(13) & Chr(10)
aa = aa & "你认为这样行吗？"
Text1.Text = aa
End Sub

Private Sub Command1_Click()
LineCnt = TextBoxLineCnt(Text1)
'每增加一行加上180,当然是以默认的字体大小而言
maxline = Text1.Height \ 180 '计算textbox能装下几行
jj = (maxline - LineCnt) \ 2 '垂直居中,(textbox总行数-Text1的总行数)整除2
For i = 1 To jj '装上几行空白
Text1.Text = Chr(13) & Chr(10) & Text1.Text
Next i
MsgBox "总共有" & CStr(LineCnt) & "行文字,看看垂直居中了吗？"
End Sub

Public Function TextBoxLineCnt(ctl As TextBox) As Long '计算总行数的函数
TextBoxLineCnt = SendMessage(ctl.hwnd, EM_GETLINECOUNT, 0, 0)
End Function
