مشكل در اتصال access از طريق asp.net
با سلام
من سعي كردم يك بانك اطلاعاتي اكسس را با Microsoft Jet 4.0 OLE DB Provider به asp.net متصل كنم اما بعد از اجرا error ذيل ظاهر مي شود،ممنون ميشوم اگر كسي راهنمائي كند مشكل كجاست؟ ضمنا شايد نكات ذيل هم براي تشخيص مشكل مفيد باشد:
- در هنگام اتصال پاسخ Test Connection بصورت Test Connection Succecded است.
-بعد از اتصال بانك، يك ايكون بانك اكسس همنام اما با يك علامت قفل در گوشه آن هم ايجاد مي شود و اگر اتصال را قطع كنيم آن ايكون هم ديده نمي شود.
-براي برقراري ارتباط با DataGrid كد ذيل را نوشته ام:
Dim myReader As System.Data.OleDb.OleDbDataReader
OleDbConnection1.Open()[/COLOR
myReader = OleDbCommand1.ExecuteReader()
DataGrid1.DataSource = myReader
DataGrid1.DataBind()
