Sep 20th, 2009

this is my code

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
If Me.txtOldPassword.Text = pwd Then
                Dim oledbcom1 As New OleDb.OleDbCommand
                oledbcom1.CommandText = "Update login Set password = ?"
 
                oledbcom1.Connection = oledbcon
 
                oledbcom1.Parameters.Add("?", OleDb.OleDbType.VarChar)
                oledbcom1.Parameters(0).Value = Me.txtNewPassword.Text.Trim
 
                oledbcom1.ExecuteNonQuery()
 
                oledbcon.Close()
end if
If Me.txtOldPassword.Text = pwd Then
                Dim oledbcom1 As New OleDb.OleDbCommand
                oledbcom1.CommandText = "Update login Set password = ?"

                oledbcom1.Connection = oledbcon

                oledbcom1.Parameters.Add("?", OleDb.OleDbType.VarChar)
                oledbcom1.Parameters(0).Value = Me.txtNewPassword.Text.Trim

It might help if you posted the exact error message and indicated what database you were using

Sknake is right, you need to provide the error message for anyone to provide detailed help other then guessing at whatelse might be going on in your code. For instance, I do not see where you are opening the database connection although you may be doing that elsewhere in the program.

Also is this a single user program, meaning there can be only one person with an account and login? I dont see a where clause in your update query string meaning if there is more then one account, it will update every record in that table.

I am going to suggest you name the params.

Ex:

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
                oledbcom1.CommandText = "Update login Set password = @Password"
 
                oledbcom1.Parameters.Add("@Password", OleDb.OleDbType.VarChar).Value = Me.txtNewPassword.Text.Trim
                oledbcom1.CommandText = "Update login Set password = @Password"

                oledbcom1.Parameters.Add("@Password", OleDb.OleDbType.VarChar).Value = Me.txtNewPassword.Text.Trim

Hope this Helps...

I could not get it to work using the '?' as the parameter name. I had to give it an actual name; like CodeDoctor suggested above.

To comment about the above post, "Password" is not a reserved keyword in ms access.
