Dim Rdr As OleDbDataReader = Cmd.ExecuteReader()
Dim intCount As Integer = 0 ' Create a loop variable.
Do While Rdr.Read() ' While this statement is 'TRUE', e.g. there is a valid record.
strResult = "txt" & strFields(intCount).Replace("f", "") 'Remove any instances of 'f', e.g. the prefix of the string.
strResult.Text = Rdr.Item(strFields(intCount).ToString)
'Set the text-box to the correct value from the database.
' This will allow me to go through several text boxes, and grab their corresponding values from the database.
intCount += 1
Loop
我真的非常感谢任何可以提供的帮助,谢谢 试试这段代码
CType( Me.Controls("strResult"),TextBox).Text = Rdr.Item(strFields(intCount).ToString)
