Question

It was hard to find the correct question topic. Well, let me elaborate more. I’m making a barcode generator simple webapp. It is for our warehouse team.

I made a class named SqlComm where I handle all SQL connection related thing. Then, I have a query (the query is just about counting a column where some Date in between). I use the query for setting the array size. Later, it loops through a for cycle and adds each new label to a placeholder. Sadly, the placeholder is not showing my new labels just created.

c# (codebehing)

  int index = 0;
  int iLength = 0;

  dt = SqlComm.SqlDataTable("SELECT [Lenum] FROM [SUIDonMachineTable] WHERE MachineTimestamp  BETWEEN CONVERT(datetime,'"+strDayFrom+"', 121) AND CONVERT(datetime,'"+strDayTo+"', 121) AND Station ='NG08NX1BT'");

  object obj = new object();
  obj = SqlComm.SqlReturn("SELECT COUNT (Lenum) FROM [SUIDonMachineTable] WHERE MachineTimestamp  BETWEEN CONVERT(datetime,'"+strDayFrom+"', 121) AND CONVERT(datetime,'"+strDayTo+"', 121) AND Station ='NG08NX1BT'");
  iLength = Convert.ToInt32(obj);
  Label[] labels = new Label[iLength];

  for (index = 0; index == iLength; index++)
     {                        
         labels[index] = new Label();
         labels[index].Text = (string)dt.Rows[index]["Lenum"];
         PH.Controls.Add(labels[index]);                                
     }

asp.net (placeholder part)

<asp:PlaceHolder ID="PH" runat="server"></asp:PlaceHolder>

Answer 1

for (index = 0; index < iLength; index++)

Try it.
