Crystal Reports empty when printed during runtime(without viewer)
I'm developing a small POS system using VB.Net , MS Sql and Crystal Reports. I have no trouble viewing reports using Cry Rep Viewer. But when i try to print a bill during runtime the report becomes empty. Following is the sequence i'm executing within the procedure.
Generate bill no
Deduct qty from stocks
add the transaction from temp table to final sales table
print bill
delete temp table transactions
clear for next transaction
But my problem comes during the bill printing. Bill does not pickup the necessary records from the sales table. Following is my code for the end transaction. (I am using few of my own methods and functions which are from another class and im also using a fix bill no for testing)
Code:
Private Sub endCurrentTransaction()
Try
Dim sqlTempBill As String = "SELECT * FROM tb_transactions where cur_user='" & curUser & "'"
Dim sqlSales As String = "SELECT * FROM tb_sales where bill_no=''"
'Get Bill No
Dim newBillNo As String = generateBillNo()
'Deduct IT qty
Dim tempBill As DataTable
tempBill = myTbClass.myFunctionFetchTbData(sqlTempBill)
Dim i As Integer = 0
Dim curQty As Double = 0
Dim trQty As Double = 0
Dim updatedQty As Double = 0
For i = 0 To tempBill.Rows.Count - 1
curQty = 0
'Get the Current stock qty
Dim sqlgetCurQty As String = "SElECT cur_qty FROM tb_stock where it_batch_code='" & tempBill.Rows(i).Item("it_batch_code") & "'"
conn.Open()
Dim SqlCmdCurQty As New SqlCommand(sqlgetCurQty, conn)
Dim DataReadercurQty As SqlDataReader = SqlCmdCurQty.ExecuteReader
While DataReadercurQty.Read()
curQty = DataReadercurQty.Item(0)
End While
DataReadercurQty.Close()
conn.Close()
trQty = tempBill.Rows(i).Item("qty")
updatedQty = curQty - trQty
Dim sqlUpdateQtyString As String = "UPDATE tb_stock SET cur_qty=" & Math.Round((updatedQty), 3) & " Where it_batch_code='" & tempBill.Rows(i).Item("it_batch_code") & "'"
conn.Open()
Dim SqlCmdQty As New SqlCommand(sqlUpdateQtyString, conn)

Hello dilhanmai,
Your code appears to referring to several objects that presumably are on some form. Without those it is impossible to further examine your code properly.
yours,
