DB transaction error

I try to use a transaction to group several DB update together

But I have the following error message see attachment

Does anyone know what's wrong ???


Global_Data.CnPolitis.Open() 'Connector open

' 1- New transaction
Dim OleDbTrans As OleDbTransaction
Dim CmdOleDb As New OleDbCommand()
OleDbTrans = Global_Data.CnPolitis.BeginTransaction
CmdOleDb.Connection = Global_Data.CnPolitis
CmdOleDb.Transaction = OleDbTrans
Try
...
CmdOleDb = New OleDbCommand("AjoutDossier", Global_Data.CnPolitis)

CmdOleDb.CommandType = CommandType.StoredProcedure

CmdOleDb.Parameters.Clear()

Param = New OleDbParameter()
Param.ParameterName = "@TYPEDOSSIER"
Param.Direction = ParameterDirection.Input
Param.OleDbType = OleDbType.VarChar
Param.Value = ComboBoxTypeDossier.SelectedValue
CmdOleDb.Parameters.Add(Param)

------->>>>> CmdOleDb.ExecuteNonQuery() 'ERROR


End try


If I put OleDbTrans in comment It work fine but if one update fail, the other are in the DB (Order detail without Order header)

Thanks for your help :D :D

Try using:

VB Code:

Dim OleDbTrans As OleDb.OleDbTransaction = cnnObject.BeginTransaction()

The error occurs when I execute the line "CmdOleDb.ExecuteNonQuery"

Any idea ?
