Drop down list display 0 - sql

strsql = "Select Sup_Name + '-----' + Sup_Code As Supdisplay , Sup_Code From kjm_supplier_profile Order By Sup_Name "
cmd = New MySqlCommand(strsql, Conn)
rdr = cmd.ExecuteReader
strddl.DataSource = rdr
strddl.DataTextField = "Supdisplay"
strddl.DataValueField = "Sup_Code"
strddl.DataBind()
strddl.Items.Insert(0, New ListItem("Please Select Supplier", ""))
rdr.Close()
This is to bind the data to the drop-down list with two data. But the drop-down list display 0

strsql = "Select Sup_Name + '-----' + Sup_Code As Supdisplay , Sup_Code From kjm_supplier_profile Order By Sup_Name "
cmd = New MySqlCommand(strsql, Conn)

Program not responding fast enough

To get started I created a program at work to read our network tools and store the retrieved data to our database. No problem but the way I set it up originally was every tool had its own instance and was hard coded for each tool.
Now I was tasked with making the program more user friendly so I can send it to other places. So now I database the IP address of tool and location on assembly line so I can cross reference while the code is executing.
On the new program I created an array of my Tool Reader class:
Dim TB(50) As ReadAtlascopco
Then I run through this loop on form load:
Private dict As New Dictionary(Of Timer, Label)()
Private Sub CreateTimers()
For i = 0 To IPCount
TB(i) = New ReadAtlascopco
' timer(i) = New Timerarray
Next
For i As Integer = 1 To IPCount
C = i - 1
timer = New Timer() With {.Interval = 250, .Enabled = True, .Tag = i.ToString}
AddHandler timer.Tick, (AddressOf timer_Tick)
' timer.Interval = (100 * i)
label = New Label()
label.Name = "label" & i
label.Location = New Point(10, 10 + i * 25)
label.Font = New Font("Sans Serif", 9, FontStyle.Bold)
label.AutoSize = True
'label.Width = 100
'label.AutoEllipsis = False
label.TabIndex = i
label.Visible = True
Me.Controls.Add(label)
dict(timer) = label
TB(C).ipaddress = TBData(C)
TB(C).StartConnection()
timer.Enabled = True
timer.Start()
Next
Then I go through the timer tick event. Everything works great up until this point. Once I go through the tick event it starts lagging and I miss data.
Is there a way to speed this process up?
Here is the tick event:
Private Sub timer_Tick(ByVal sender As Object, ByVal e As EventArgs)

The class that is being referenced is one that I created and is working but like I said everything is slow. It seems to hang for 3 to 5 seconds in a single tick event.
As of now I only have 21 tools setup and it will take about 15 to 30 seconds to cycle through all.

There are a couple of things wrong with your query.
You havent left any spaces once a line in code is finished and whole query may look like they are separate lines but it is a one long string without any spaces.
I have added spaces in the following piece of code at the end of each line.
("SELECT [txnStudentFeeHead].[FeeHeadID],[mstFeeHead].[FeeHeadName]," & _
"[mstFeePlan].[Amount] " & _
"FROM " & _
"[txnStudentFeeHead] " & _
"INNER JOIN " & _
"[mstFeeHead] " & _
You have put your variables in sqaure brackets [] , which means SQL Server will treat them as SQL Server Object(table name, Column Name) names and not as Variables. Remove the Square brackets.
"WHERE " & _
"([txnStudentFeeHead].[StudentID] = #StudentID) " & _
"AND" & _
"([mstFeePlan].[SessionID] = #SessionID) " & _
"AND" & _
"([mstFeePlan].[ClassID] = #ClassID) ", sqlcon)
Solved it myself by long time of effort and headache
