I have 4 Datetimepicker. the 2 datetimepicker is on dateformat(datefrom,dateto) and the other 2 datetimepicker is on Timeformat(timefrom,timeto).
I want to search a table that display only in datagridview that will display only start on Date from and time from to date to and time to... But my code doenst work.
here's my code:
Dim fromto As String = String.Empty
fromto &= "Select * from setplan where endplan >='" & dtimefrom.Text & "'and endplan >='" & dtimeto.Text & "' and [Dateinput] >='" & ddatefrom.Text & "' and [dateinput] <= '" & ddateto.Text & "'"
Dim connection As String = ("provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Administrator\Documents\planning.accdb;Persist Security Info=False;")
Using conn As New OleDb.OleDbConnection(connection)
Using cmd As New OleDb.OleDbCommand(fromto)
With cmd
.Connection = conn
.CommandType = CommandType.Text
.CommandText = fromto
End With
Try
conn.Open()
cmd.ExecuteNonQuery()
Dim da As New OleDb.OleDbDataAdapter(cmd)
Dim ds As New DataSet
da.Fill(ds)
If ds.Tables.Count > 0 Then
DataGridView1.DataSource = ds.Tables(0)
End If
conn.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Using
End Using
End Sub
You need formatted string expressions for your date/time values:
fromto &= "Select * from setplan where endplan >= #" & ddateto.Value.ToString("yyyy'/'MM'/'dd") & " " & dtimeto.Value.ToString("HH':'mm") & "# and [dateinput] >= #" & ddatefrom.Value.ToString("yyyy'/'MM'/'dd") & " " & dtimefrom.Value.ToString("HH':'mm") & "#"

So my code is going through the various components and creates bundles using the BuildKnittingRecords sub for the various components. My code works well when it creates the bundles for the Case "Sleeve", "Front", "Body", "Back" but when it gets to Case "Collar22-32" it gets stuck in the do until loop and as a result will keep on adding to PnlsToProduce(until it crashes cos the number is too big) instead of only running through the do until loop when it finds that component
Private Sub knittingdetailsheaderdataset()
bundlenum = 1
Dim SQL As String
Dim Adapter As New OleDbDataAdapter
Dim dt As New DataTable
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand()
SQL = "Select bla bla
FROM bla bla
INNER Join bla bla"
(it's a very long sql statement, and not relevent to my issue)
cmd.Connection = con
cmd.CommandText = SQL
Adapter.SelectCommand = cmd
Adapter.Fill(dt)
For dr As Integer = 0 To dt.Rows.Count - 1
componentName = dt(dr)(6)
knittOrderID = dt(dr)(4)
componentID = dt(dr)(3)
sizeID = dt(dr)(5)
qtyppnl = dt(dr)(10)
Select Case componentName
Case "Sleeve", "Front", "Body", "Back"
MxBndleSz = 36
PnlsToProduce = dt(dr)(11)
BuildKnittingRecords(MxBndleSz, componentID, sizeID, PnlsToProduce, qtyppnl, knittOrderID, bundlenum)
Case "Collar22-32"
MxBndleSz = 200
PnlsToProduce = 0
Do Until componentName <> "Collar22-32" Or dr = dt.Rows.Count - 1
PnlsToProduce += dt(dr)(11)
Loop
Select Case PnlsToProduce
Case 50 To 100
PnlsToProduce = PnlsToProduce + 1
Case 101 To 250
PnlsToProduce = PnlsToProduce + 2
Case Is > 250
PnlsToProduce = PnlsToProduce + 3
End Select
BuildKnittingRecords(MxBndleSz, componentID, sizeID, PnlsToProduce, qtyppnl, knittOrderID, bundlenum)
End Select
Next
End Using
End Sub
Hence my question is, why is it doing this and how do I solve it?
This is my code for the BuildknittingRecord() sub, not sure if it's relevant in solving my issue:
Private Sub BuildKnittingRecords(ByRef MaxBundleSz As Integer, ByRef compID As Integer, ByRef sizeID As Integer, ByRef PnlsToproduce As Integer, ByRef QtyPerPanel As Integer, ByRef KnittingOrderID As Integer, ByRef bundlenum As Integer)
pnls2prod = PnlsToproduce
Dim cmdstring As String
Do Until pnls2prod < 10
If bundlenum < 10 Then
bundleNo = txtbatchno.Text & "-K0" & bundlenum
Else
bundleNo = txtbatchno.Text & "-K" & bundlenum
End If
bundlenum += 1
If pnls2prod <= MaxBundleSz Then
PanelsToMake = pnls2prod
cmdstring = " INSERT INTO [KN - KnittingDetailsHeader] (BatchNo, BundleNo, ComponentID, SizeID, PanelsToMake, QtyPerPanel, KnittingOrderID) VALUES('" & txtbatchno.Text & "', '" & bundleNo & "', " & compID & ", " & sizeID & ", " & PanelsToMake & ", " & QtyPerPanel & ", " & KnittingOrderID & ");"
Using con As New OleDbConnection(cnString)
Dim cmd As New OleDbCommand(cmdstring)
cmd.CommandType = CommandType.Text
cmd.Connection = con
cmd.Connection.Open()
cmd.ExecuteNonQuery()
End Using
Exit Do
Else
If pnls2prod < 10 Then
PanelsToMake = pnls2prod + MaxBundleSz
cmdstring = " INSERT INTO [KN - KnittingDetailsHeader] (BatchNo, BundleNo, ComponentID, SizeID, PanelsToMake, QtyPerPanel, KnittingOrderID) VALUES('" & txtbatchno.Text & "', '" & bundleNo & "', " & compID & ", " & sizeID & ", " & PanelsToMake & ", " & QtyPerPanel & ", " & KnittingOrderID & ");"

It looks like there is no opening quote in the values of the first two Inserts.
Here is the problem, when I insert an image (let's call it Data A) which is 1.32MB, it will be inserted successfully. But if I will insert again Data A(but it will update now because i used UPSERT, see my code), it will not be updated and it will result to connection time out.
But when i insert another data (Data B) which is only 4KB, it will also be inserted successfully and if I will insert again into it(which is update), it will be updated successfully. What can I do? I cannot understand the problem. I already made my command timeout for 2 mins but nothing happened and it just loaded forever. I also used sql transaction but it did nothing.
Here is my code:
Protected Sub btnSave_Click(sender As Object, e As EventArgs) Handles btnSave.Click
Dim strConnString As String = DataSource.ConnectionString
Using con As New SqlConnection(strConnString)
Dim SQLStr As String
Dim base64String = TextArea1.Value

Dim FileSizeOfIMG As String
FileSizeOfIMG = imageBytes.Length
Dim ImageTypeDataOfImage As New SqlParameter("#Data", SqlDbType.Image)
ImageTypeDataOfImage.Value = imageBytes
SQLStr = "SELECT 1 FROM [Patient_Data].[dbo].[tbPatientImage] where HospNum='" & Session.Item("HospNum") & "'" & _

I haven't figured out what causes this but i have figured out a remedy by having a delete query first then insert data.
SQLStr = "delete FROM [Patient_Data].[dbo].[tbPatientImage] where HospNum='" & Session.Item("HospNum") & "'" & _
" and IDNum='" & Session.Item("IDNum") & "' and FileType= '" & lblHeader.Text & "'"

I'm trying to show a 'customized' ToolTip on an MSChart on an asp.net page, using vb.net
The chart displays OK, but I'm trying to get it to show the 'YEAR' as part of the tooltip, as well as the XY values.
I can't figure out how to do it.
Here's the code that I'm using to build the chart:
dt = New DataTable
dt.Columns.Add("Topic")
dt.Columns.Add("Value")
dt.Columns.Add("Year")
For i = 0 To t_YEARS.Count - 1
Sql = "SELECT att_Topic, att_Value, att_Year from Att "
Sql += " WHERE att_Year = '" & t_YEARS(i) & "' "
conn.ConnectionString = strConnString
conn.Open()
cmd = New SqlCommand(Sql, conn)
dr = cmd.ExecuteReader
While dr.Read
dt.Rows.Add(dr(0), dr(1), dr(2))
End While
dr.Close()
cmd.Dispose()
conn.Close()
Next
Chart1.DataSource = dt
Chart1.Series("Series1").XValueMember = "Topic"
Chart1.Series("Series1").YValueMembers = "Value"
Chart1.Series("Series1").ToolTip = "#VALX - #VALY"
Chart1.ChartAreas("ChartArea1").Area3DStyle.Enable3D = True
Chart1.DataBind()
Well, there may be a better answer, but I figured out a work-around anyhow ... I'm adding the YEAR to the axislabel. Then, in chart1_customize, changing the color of the bar, based on different axislabel. Seems to work.
dt = New DataTable
dt.Columns.Add("Topic")
dt.Columns.Add("Value")
dt.Columns.Add("Year")
For i = 0 To t_YEARS.Count - 1
showDATA = False
Sql = "SELECT att_Topic, att_Value, att_Year, att_Data from BWS_Att "
If (RBL_LIMIT.SelectedValue = 1) Then
showDATA = True
Sql += " WHERE att_Attrib = 'Location' "
Sql += " AND att_Data IN ('" & String.Join("','", t_LOCS) & "')"
ElseIf (RBL_LIMIT.SelectedValue = 2) Then
showDATA = True
Sql += " WHERE att_Attrib = 'Department' "
Sql += " AND att_Data IN ('" & String.Join("','", t_DEPTS) & "')"
Else
Sql += " WHERE att_Attrib = 'Company' "
End If
Sql += " AND att_Year = '" & t_YEARS(i) & "' "
Sql += " AND att_Topic IN ('" & String.Join("','", t_CATS) & "')"
Sql += " Order By att_ind"
conn.ConnectionString = strConnString
conn.Open()
cmd = New SqlCommand(Sql, conn)
dr = cmd.ExecuteReader
While dr.Read
'dt.Rows.Add(dr(0), dr(1), dr(2))
thisYR = dr(2).ToString
If (lastYR <> thisYR) Then
Chart1.Series("Series1").Points.Add(vbEmpty)
Chart1.Series("Series1").Points.Add(vbEmpty)
lastYR = thisYR
End If
If (showDATA = True) Then
Chart1.Series("Series1").Points.AddXY(dr(2).ToString & "|" & dr(3).ToString & ":" & dr(0).ToString, dr(1))
Else
Chart1.Series("Series1").Points.AddXY(dr(2).ToString & ":" & dr(0).ToString, dr(1))
End If
Chart1.Series("Series1").ToolTip = " #AXISLABEL | #VALY"
End While
dr.Close()
cmd.Dispose()
conn.Close()
Next

I think you are getting an error by not enclosing the Date inside Pound signs. You have to do this in Jet (Access) when using variables not parameters.
VALUES('#" & DateTime.Now.Date & "#',...
I also took the liberty of refactoring this code for you since you are creating a new connection for each record which is bad news. Use a Try Catch Finally block and move all that stuff outside the For Loop (please see below)
Function recordOrder()
objDT = Session("Cart")
Dim intCounter As Integer
Dim con2 As New System.Data.OleDb.OleDbConnection
Dim myPath2 As String
myPath2 = Server.MapPath("faraxday.mdb")
con2.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" <-- etc
Dim myCommand2 As New System.Data.OleDb.OleDbCommand
myCommand2.Connection = con2
con2.Open()
Try
For intCounter = 0 To obDT.Rows.Count - 1
objDR = objDT.Rows(intCounter)
myCommand2.CommandText = "INSERT INTO order(order_date,coupon_id,customer_id,quantity)" _
& "VALUES ('#" & System.DateTime.Now.Date & "#','" & Int32.Parse(objDR("ID")) & "','" & Int32.Parse(custID) _
& "','" & Int32.Parse(objDR("quantity")) & "')"
myCommand2.ExecuteReader()
Next
Catch ex As Exception
'handle errors here
Finally
If con2.State = ConnectionState.Open Then
con2.Close()
End If
End Try
End Function
Remember to mark as answered if this helps.
I've sorted it out by removing the single quotes. Thanks everybody to contributed to this.
