以下のコードで、インデックスが正しくないというエラーが表示されます。これは SQL ステートメントのエラーであると想定していますが、何が問題なのかわかりません。
Private Sub btnStock_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStock.Click
frmStock.Visible = True
Dim SQLCmd As String
SQLCmd = "SELECT PartID,PartName,PartStockLevel,MakeName,ModelName FROM tblParts WHERE PartStockLevel <= StockWarnLevel;"
RunSQLCmd("dt", SQLCmd)
Dim inc As Integer = 0
Dim NoLowStock As Boolean
If DataTable IsNot Nothing AndAlso DataTable.Rows.Count > 0 Then
frmStock.txtPartID.Text = DataTable.Rows(inc).Item(0)
frmStock.txtName.Text = DataTable.Rows(inc).Item(1)
frmStock.NUDStockLvl.Value = DataTable.Rows(inc).Item(2)
frmStock.txtMake.Text = DataTable.Rows(inc).Item(3)
frmStock.txtModel.Text = DataTable.Rows(inc).Item(4)
Else
frmStock.lblLowStock.Visible = True
frmStock.btnFirstRecord.Visible = False
frmStock.btnIncDown.Visible = False
frmStock.btnIncUp.Visible = False
frmStock.btnLastRecord.Visible = False
NoLowStock = True
End If
If NoLowStock = False Then
frmStock.Panel1.Visible = False
End If
End Sub
Public Sub RunSQLCmd(ByVal DTorDS As String, ByRef SQLCmd As String)
DataAdapter = New OleDb.OleDbDataAdapter(SQLCmd, con)
ConnectDB()
Try
If DTorDS = "dt" Then
DataTable = New DataTable
DataAdapter.Fill(DataTable)
Else
DataSet = New DataSet
DataAdapter.Fill(DataSet, "srcDataSet")
End If
Catch ex As Exception
con.Close()
End Try
con.Close()
End Sub
前もって感謝します!
