在表单上,我有13 textbox
。当用户单击“保存”按钮时,Access会调用API并将这些文本框中的值传递给API(通过HTTP REST)
有些字符是不允许的,例如"
不允许通过API保存。因此,我想限制用户输入这些字符。
目前我创建了一个Public
Function
来自KeyPress
事件,以检查字符是否被允许。但我必须在每个textbox
KeyPress
事件中调用此函数。 有没有办法在所有文本框中都不允许"
?
功能
Public Function CharsNotAllowed(myChar As Integer) As Integer
If myChar = 34 Then
Beep 'Let the user know they hit an illegal key
CharsNotAllowed = 0 'Don't let the keystroke through
Else
CharsNotAllowed = myChar
End If
End Function
功能调用
Private Sub StudentName_KeyPress(KeyAscii As Integer)
KeyAscii = CharsNotAllowed(KeyAscii)
End Sub
Private Sub StudentClass_KeyPress(KeyAscii As Integer)
KeyAscii = CharsNotAllowed(KeyAscii)
End Sub
'and so on for all the 13 text boxes
注意:34
代表"
答案 0 :(得分:3)
你试过Form
级吗?顺便说一下,大多数时候用户都会复制和粘贴,这样就可以让用户输入那些不需要的字符(只是提醒:))
Private Sub Form_KeyPress(KeyAscii As Integer)
If ActiveControl.ControlType = 109 Then 'only for textboxes
KeyAscii = CharsNotAllowed(KeyAscii)
End If
End Sub
