Well, without seeing the code and the line that the error occured on, it's pretty impossible to tell you what's going wrong.

hi man Vuyiswa here,

Do you want to Do Something like this ?

<br />
  Public Sub TimeAlloc(ByVal strEmployeeNumber As String)<br />
<br />
        Dim strSelectNum As String = "SELECT * FROM tblEmployeeAllocation WHERE EmployeeNumber = ?"<br />
<br />
        Dim strcon As String = "Provider=Microsoft.Jet.OLEDB.4.0;Password="""";User ID=Admin;Data Source=C:\devELOPMENT\WINTur\TurN.mdb"<br />
<br />
        Dim sda As OleDbDataAdapter<br />
<br />
        Dim dsEmployeeTime As New DataSet<br />
<br />
        Dim cmdDatabase As OleDb.OleDbCommand<br />
<br />
        Dim conDatabase As New OleDbConnection(strcon)<br />
<br />
        cmdDatabase.Parameters.Add("EmployeeNumber", strEmployeeNumber)<br />
<br />
        cmdDatabase.Connection = conDatabase<br />
<br />
        sda.SelectCommand = cmdDatabase<br />
<br />
        Dim bNewTimeAllocation As Boolean<br />
<br />
<br />
        'need to determine if this is a new allcation WHERE EmployeeNumber exists in tblTimeAllocation<br />
        'txtEmployeeNumber.Text'<br />
<br />
        Try<br />
<br />
            conDatabase.Open()<br />
<br />
<br />
            sda.Fill(dsEmployeeTime, "tblEmployeeAllocation")<br />
<br />
            If dsEmployeeTime.Tables("tblEmployeeAllocation").Rows.Count = 0 Then<br />
<br />
                bNewTimeAllocation = True<br />
            Else<br />
<br />
                bNewTimeAllocation = False<br />
<br />
            End If<br />
<br />
            conDatabase.Close()<br />
<br />
        Catch exc As OleDb.OleDbException<br />
<br />
            MsgBox(exc.Message)<br />
        End Try<br />
    End Sub<br />

IvanIT Wrote|The function I am using is outlined below

This is not a Function is a Sub, a Function will return a Value,now i see you have Boolean Variables i suppose you want to return them? if so remove the Sub keyword and use Function and tell your function to return Boolean. lastly my question in the Following line

<br />
Dim recEmployee As DataRow = dsEmployeeTime.Tables(0).Rows(0)<br />
<br />
If recEmployee.IsNull("EmployeeNumber") Then<br />
<br />

What did you want to achieve here?

Thanks

The only place you're going to find a script like that is if you write it. We're not here to write your code for you. We'll help you with code you write though.

No-one is going to trawl through all this source to try to find which line is 207.

I'd guess that the operator = error has to do with VB doing an implicit conversion to a type that does have operator =.

Error 4 is self explanatory. VB sucks. It won't let you call an event, you have to call RaiseEvent.

Error 5 looks like the convertor has failed to properly convert a constructor, at a guess

Error 6, 7, and 8 are all because VB sucks and is not case sensitive. The original code had Mirrored and mirrored defined ( probably as a private variable and a public property. Change mirrored to _mirrored through the code, and then they will not collide.

You can't add the line drawing controls directly to a panel or other container. You have to first add the drawing control's "Surface" or "Drawing Container" control to the panel control, then add the line and oval controls to that surface control.

I can't remember what it's called, but it's quite obvious what it is if you look through the power pack library the line and oval controls are in.

So where is the data in the ListView comming from??

Handle the SelectedIndexChanged event of the ListView to get the index of the item in the ListViews Items collection. Once you have that, you can grab the data from the ListViewItem in the collection, and all of the SubItems of the ListViewItem that was selected. You'll have to populate the grid manually with this data or put it into a DataTable object that you build and bind the DataGridView to that.

There's a bunch of different ways of doing this...

Threading event control question

cstrader23227-Feb-08 2:36

27-Feb-08 2:36

If I run a control method on a BGW why don't the event callbacks that it creates run on the background thread? They seem to fire on the main thread.

Thanks

Re: Threading event control question

Dave Kreskowiak27-Feb-08 6:17

Dave Kreskowiak

27-Feb-08 6:17

You're question is a bit confusing. Which event callbacks are you talking about?? Are you referring to the ProgressChanged, RunWorkCompleted, ..., events exposed by the BGW?? Or are you talking about the events exposed by your other controls method??

If the BGW events, then those events are automatically marshaled back to the UI thread so the developer doesn't have to do anything different than any other controls in order to handler them. It's just an ease of use requirement when the BGW was designed.

Sorry, let me be more specific. I have a third party control that causes events to be fired. Even if I start that method on a BGW the events fire on the main thread. I guess my question is how does an event know which thread it was called on? Is it possible to make a method fire its events on a separate thread?

Thanks again.

If the control was created by the UI thread, or dropped on the form, it stays on the UI thread. Events cannot be made to arbitrarily fire on a different thread.

adding progress bar

johnjsm27-Feb-08 2:09

27-Feb-08 2:09

Hi,
I need to add a progress bar that will progress with the amount of bytes read of a file. I am performing a CRC32 on a large file and I would like to display the progress using the progress bar and also text displaying the percentage done. The crc32 is already running on a seperate thread. Can anyone help.

This is the code for getting the crc32

Dim f As FileStream = New FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, 8192)
crc = c32.GetCrc32(f)
lblCRC32V.Text = Hex(crc)
f.Close()

Thanks

If this CRC library you're using exposes a method to report progress, you'll be in business. If not, you won't be able to do this unless you have access to the source code for the library and add support for reporting progress.

Does the library support this?

OK. So add a little code to the main processing loop to fire an event every so often reporting the percentage complete.

You consumer code should create an instance of this class, wireup the event you write and use the data from that event to update the progress bar.

Seeking VB sample using GPS Intermediate Driver parsed API

twoods27-Feb-08 1:32

twoods

27-Feb-08 1:32

Newbie here, "Hello" forum.

As the title suggests I'm looking to use the GPS Intermediate Driver parsed API through VB. I'm not a C programmer so this would be a great solution for us VBers...

The API appears to have just 4 functions and eliminates having to directly code to the com port, perfect. (http://msdn2.microsoft.com/en-us/library/bb202033.aspx)

GPSOpenDevice
GPSGetPosition
GPSGetDeviceState
GPSCloseDevice

I'm not familiar enough with how to implement the API to be able to get off the ground, I'm hoping somebody might be able to help out.

Thanks.

TW,

Strange problem about msinet while using getheader method

Member 438462427-Feb-08 1:02

Member 4384624

27-Feb-08 1:02

i have got a Strange problem about msinet.ocx while using getheader method.
it is:
i write this code

Private Sub Inet1_StateChanged(ByVal State As Integer)<br />
Select Case State<br />
  Case 8<br />
  If app_status = 1 Then<br />
    'xnei_header = Inet1.GetHeader<br />
    Text3.Text = Text3.Text & vbCrLf & "error: " & vbCrLf & xnei_header<br />
    app_status = 2<br />
  Else<br />
    xnei_header = Inet1.GetHeader<br />
    Text3.Text = Text3.Text & vbCrLf & "error: " & vbCrLf & xnei_header<br />
  End If<br />
  If app_status = 3 Then<br />
    Text6.Text = Text6.Text & vbCrLf & "error: " & vbCrLf & xnei_header<br />
    app_status = 4<br />
  End If<br />
  Case 12<br />
    If app_status = 2 Then<br />
      Text3.Text = Text3.Text & ResponseInfo & vbCrLf & vbCrLf & Inet1.GetHeader<br />
    End If<br />
    If app_status = 4 Then<br />
      Text6.Text = Text6.Text & ResponseInfo & vbCrLf & vbCrLf & Inet1.GetHeader<br />
    End If<br />
End Select<br />
End Sub

the code write for auto_login to a website
when i post the correct user/pwd data to the site,it will return a http
header with values=302 and if the user/pwd wrong,it will be 200
then inet1 will go on fetching the site
i found i can use getheader method to see if the return value is 302 or 200 while state change to 8
and these code work normally at my home PC(it use a adsl net)
but can not work at my school PC(it use a lan net and after a route)
the vbide show error like this:
RUNTIME ERROR : "35756"
Unable to complete request!

it seems a error accur at xnei_header = Inet1.GetHeader

some people told it is because my pc is after a route
isn't it?
if it is ,please tell me how to solve it, thx

It probably has something to do with a proxy or firewall server in your schools network. You'll have to examine the returned page data from the proxy in order to figure this one out. It's possible you're not even getting to the page at all because it may be blocked by the proxy.
