我在我的網站(edituser.aspx)中有一個編輯用戶頁面。用戶名和密碼被放置在一個Access數據庫中,並在FormView中顯示它們。像這樣:FormView調用綁定中的字符串函數
<asp:FormView
ID="EditForm"
runat="server"
DefaultMode="Edit">
<EditItemTemplate>
<strong>username:</strong><br />
<asp:TextBox ID="usernameIDTextBox" runat="server" Text='<%# Bind("usernameID") %>' /><br />
<strong>Password:</strong><br />
<asp:TextBox ID="passwordIDTextBox" TextMode="password" runat="server" Text='<%# Bind("passwordID") %>' /><br />
... .
我在數據庫加密的密碼,但我雖然有解密功能,但我不知道如何使用它綁定短語內。例如,我試過
<%# decrypt(Bind("passwordID")) %>
並且這不起作用。
注:我使用asp.net 3.5,這是我對裏面edituser.aspx.vb解密函數:
Public Function Decrypt(ByVal strDecoded_Pword As String) As String
On Error Resume Next
Dim i, ct As Integer
Dim letter, dec, StrValappend, strVal As String
dec = ""
strDecoded_Pword = StrReverse(strDecoded_Pword)
For ct = 1 To Len(strDecoded_Pword) Step 2
StrValappend = Chr(Val("&H" & (Mid(strDecoded_Pword, ct, 2))))
strVal = strVal & StrValappend
Next
strDecoded_Pword = strVal
For i = 1 To Len(strDecoded_Pword)
letter = Mid(strDecoded_Pword, i, 1)
dec = dec & Chr(Asc(letter) - i - 5)
Next
Decrypt = dec
End Function
如果我從交換機綁定到Eval。錯誤會增加:沒有給出一個或多個必需參數的值。 –
