不允许在 MS Access 的所有文本框中使用特定字母
Don't allow specific letters in ALL textbox for MS Access
在表格上,我有 13 textbox
。当用户单击保存按钮时,Access 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。
目前我已经创建了一个 Public
Function
从 KeyPress
事件调用来检查字符是否被允许。但是我必须从每个 textbox
KeyPress
事件中调用这个函数。 有没有办法不允许"
跨越所有的文本框?
函数
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
函数调用
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:34
代表"
你试过Form
关卡了吗?顺便说一句,大多数时候用户复制和粘贴,这将允许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
