Question

用VB怎么使文本框中只能输入字母

新建一个文本框，要求只能输入英文字母，输入其他的就会弹出一个对话框（好像要用msgbox,我暂时还没学）

Answer 1

你好，暂时可以这样做（选择Key_Press事件）Private Sub Text1_KeyPress(KeyAscii As Integer)
Select Case KeyAscii
If Not ((KeyAscii>=Asc("A") And KeyAscii<=Asc("Z") Or (KeyAscii>=Asc("a") And KeyAscii<=Asc("z")) Or (KeyAscii=vbKeyBack))

KeyAscii = 0
End Select
End Sub

Answer 2

比如
Private Sub Text_KeyPress(KeyAscii As Integer)
If (KeyAscii >=Asc("a") and KeyAscii <= Asc("z")) or (KeyAscii >= Asc("A") and KeyAscii <=Asc("Z")) Then
KeyAscii = KeyAscii
else
KeyAscii=0
End If
End Sub
