textbox 单行文本上下居中显示！
最近学着写一个报表系统， 结果在一个输入表中textbox 输入的数字在文本框上面，不是居中，挺难看的
请问如何设置文本才能上下居中呢？
（要设置只能输入单行数字）最好举例 谢谢！！

记住，设置 Text1 的 Multiline = True
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
