[.NET] 資料庫問題

[inkyy (阿亮都不愛我啦)]

我的程式

 Dim connStr, insertCmd As String
        connStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=asset_maintenance.mdb"
        insertCmd = "Insert Into records(Staff_ID, Inspection_Date,
Description_reasons, Complete_Date) Values(@Staff_ID, @Inspection_Date,
@Description(Reasons), @Complete_Date)"
        Dim conn As OleDbConnection, cmd As OleDbCommand
        conn = New OleDbConnection(connStr)
        conn.Open()
        cmd = New OleDbCommand(insertCmd, conn)
        cmd.Parameters.Add(New OleDbParameter("@Staff_ID", OleDbType.VarChar))
        cmd.Parameters.Add(New OleDbParameter("@Inspection_Date",
OleDbType.DBDate))
        cmd.Parameters.Add(New OleDbParameter("@Description(Reasons)",
OleDbType.VarChar))
        cmd.Parameters.Add(New OleDbParameter("@Complete_Date",
OleDbType.DBDate))
        TextBox4.Text = Now
        cmd.Parameters("@Staff_ID").Value = TextBox1.Text
        cmd.Parameters("@Inspection_Date").Value = TextBox2.Text
        cmd.Parameters("@Description(Reasons)").Value = TextBox3.Text
        cmd.Parameters("@Complete_Date").Value = TextBox4.Text
        cmd.ExecuteNonQuery()
        conn.Close()

請問一下就是我要新增資料, 可是卻一直發生問題, 可以邦我找到錯誤嗎??

推 fumizuki:錯誤訊息呢@@
推 inkyy:類型 'System.Data.OleDb.OleDbException' 的未處理例外狀況
→ inkyy: cmd.ExecuteNonQuery()到此行會出現上述訊息
推 cawQQ:會不會是你資料庫的問題??執行這段SQL指令出錯了
→ lolota:Access檔案權限不夠，你要加入asp.net的權限
