Me.WindowState = 2
       
       Label1.Caption = GetSetting(App.EXEName, "CoName", "txtco", "")
       Label2.Caption = GetSetting(App.EXEName, "CoAdd", "txtAdd", "")
       Label3.Caption = GetSetting(App.EXEName, "Cotelp", "txttelp", "")
       
       con_cashreg.Open STring2
       msql = "select * From invoicedetail "
       'If rs.State = adStateOpen Then rs.Close
       Rs2.CursorLocation = adUseClient  'For Sortinf
        
       con_cashreg.Execute (msql)
       Rs2.Open msql, con_cashreg, adOpenKeyset, adLockPessimistic, adCmdText
        
       MSHFlexGrid1.Redraw = False
 
       MSHFlexGrid1.Cols = 10
       MSHFlexGrid1.ColWidth(0) = 0
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 1
       MSHFlexGrid1.Text = "Invoice Id"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 2:
       MSHFlexGrid1.Text = "Prod Id"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 3:
       MSHFlexGrid1.Text = "Prod Name"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 4:
       MSHFlexGrid1.Text = "Unit"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 5:
       MSHFlexGrid1.Text = "Sale Price"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 6:
       MSHFlexGrid1.Text = "Quantity"
       MSHFlexGrid1.Row = 0:       MSHFlexGrid1.Col = 7:
       MSHFlexGrid1.Text = "Amount"
       
       MSHFlexGrid1.Rows = MSHFlexGrid1.Rows + 1
        
        With Rs2
            While Not Rs2.EOF
                MSHFlexGrid1.Col = 1
                MSHFlexGrid1.Text = Rs2!invoiceid
                MSHFlexGrid1.Col = 2
                MSHFlexGrid1.Text = Rs2!productid
                MSHFlexGrid1.Col = 3
                MSHFlexGrid1.Text = Rs2!ProductName
                MSHFlexGrid1.Col = 4
                MSHFlexGrid1.Text = Rs2!unit
                MSHFlexGrid1.Col = 5
                MSHFlexGrid1.Text = Rs2!saleprice
                MSHFlexGrid1.Col = 6
                MSHFlexGrid1.Text = Rs2!quantity
                MSHFlexGrid1.Col = 7
                MSHFlexGrid1.Text = Rs2!amount
                
                MSHFlexGrid1.Rows = MSHFlexGrid1.Rows + 1
                MSHFlexGrid1.Row = MSHFlexGrid1.Row + 1
                .MoveNext
            Wend
            Rs2.Close

Are you sure this

Code:

---

msql = "delete * from invoicedetail"

is empting the table?
May be TRUNCATE TABLE is better?

hi ember
sure, I am very sure invoicedetail is deleted and empty after delete
how to truncate a table? can you advise pls thanks

happy new year

From Books Online (SQLServer):

Code:

---

TRUNCATE TABLE
Removes all rows from a table without logging the individual row deletes.

Syntax
TRUNCATE TABLE name

---

I'm using access 2k is truncate support it? What is the different between truncate table and using "delete * from table" ? and What condition is required to use truncate table?

really appreciate, thanks.

Access (makes me uncertain) but:

Code:

---

Delete Method (ADO Recordset)
Deletes the current record or a group of records.

Syntax
recordset.Delete AffectRecords

Parameters
AffectRecords
An AffectEnum value that determines how many records the Delete method will affect. The default value is adAffectCurrent.
Note  adAffectAll and adAffectAllChapters are not valid arguments to Delete.

---

Is the truncate work fine in access 2k? if yes
Can you show an example code using truncate pls

really appreciate, thanks ember

How to refresh a mshflexgrid anyone help pls?

If you are deleting all in that Table then you don't need to Refresh, just use

VB Code:

MSHFlexGrid1.Rows = 1

But if you want to execute a different commandstring and you really need to Refresh then you need to execute the code in your Form_Load event again, so it would be much better if you remove that code from there and add it to another Sub and call that sub in Form_Load and whenever you need to Refresh the Grid after a change.

Also, inside that new Sub that Refreshes your Grid, add MSHFlexGrid1.Rows = 1 on top.

Yes working
Thanks Jcis
Appreciate
