I would have a separate EXE for this purpose which uses the ActiveX EXE to expose the functions to a GUI. Don't try to make the ActiveX EXE serve two purposes.

hi,every one:
i write a program to scan a special folder every 10 second.so i drag a timer control to the from. and in timer1_tick sub i write some code.it work very well under by windos xp system. but when i put the program onto another server(system is windows 2003 server),i found the timer control is NOT run,even 1 time.
so i delete the timer control,create a threading.timer object used code under:
dim tmr as threading.timer=new threading.timer(new threading.timercallback(addressof timerproc,vbnull,0,10000)
i found the sub NOT work still.

Hey, you only left this message a few hours ago. Don't be impatient. If you want instant response I'm sure that there are many consultants that would be willing to help for a fee  Remember this is a free site.
As to your question, if you can post the code which you are using we can have a look see at what the problem might be.

I'd make the following changes to the code:
1. delete the Tmr.Change() lines from your timer callback. They serve no purpose in the callback function.
2. Change this line:
Tmr = New Threading.Timer(Tcb, vbNull, 1000, 10000)
to this...
Tmr = New Threading.Timer(Tcb, Nothing, 1000, 10000)
because vbNull is not the same as Nothing in VB.

thank you for reply again.
i write tmr.change in my timer callback procedure because i am afraid of this procedure will not finish in 10 second,i think this can prevent it.
and i accept the No.2
but the original problem is i'm using a system.windows.form.timer control,and it NOT work normal also. would you like explain the reason to me?following is the original code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick<br />
....<br />
End Sub

Silly question, but is the timer enabled (in my own form initialization code I have something like this):
Timer1.Enabled = False
Timer1.Interval = 2000
Timer1.Enabled = True
Another possibility is that the Timer control is designed only for use with forms. Is the form on which it appears always active? It could also be the version of the .NET Framework you have on the server vs the one you have compiled against on your workstation. Check that they match.
...Steve

i am not a proficient programmer,but i am not a beginner too.
"timer1.enable=true " has in form1_load already.
the form will minimized once it start,do this affect the timer and lead the timer deactive? if so,many question will occur...
and the timer is used in a winform,i am sure this.
No.3,both the server and my machine has the same version of .NET(1.1.4322).
sigh.....

I'm not trying to be funny - sometimes the answers lie in the most simple of overlooked things.
Well assuming that the code works fine on your WinXP box and the same code does not work on Win2k3 Server (hazarding to state the obvious here...) there is something different about that environment.
Are there any error messages trapped by your code that could give us a clue? If not, ensure that the timer control OCX/DLL or whatever is actually on the server and registered. Also check that the service pack on your VB (Visual Studio .NET 200x?) is up to date.

i know that. sorry for my misnomer.
this program work very well on my XP machine, no any error or warning message. but on Win2003 PRO server,it strike.
i remember one thing, two weeks ago, there is another program which used timer control too, run normal on this server. since i found this problem yesterday, i ask the administrator of our LAN, he said,the server has no any change for 2 months at least.
it looks that problem is base on two diffirent environment. i think so yesterday, but i has no resolvent.

I've developed an application in VB6 to communicate with an RS232 device controled with motorola HC11. However one of the routines in my application needs to send and intel hex file to the motorola which it will process and load into flash memory for software upgrades. The HC11 is sending Xon/Xoff characters to indicate when its buffer is full but I can't seem to react quick enough with the mscomm control to prevent buffer overrun. It will work at a dreadfully slow pace but I need more speed. I know that mscomm has a handshaking property but I'm not sure how to use it to stop my data transfer. Any help would be appreciated.

Hi friends!
This might sound really elementary but i was just wondering how can i make sure that a user inputs an integer value. I've a textbox which has to be in integer format and when it is not, upon clicking the save button, my field validator should shows up and resets the textbox to "". I've tried this code but it doesn't seem to work...
If Cint(TextBox1.Text) = false then
RFV1.Validate()
TextBox1.Text = ""
Else
'does the saving
End If
It throws an exception that input string is not in correct format. How do i go about fixing this? Thanx to all!

Use a regex validator.
Or, Double has a TryParse method, but Int16, integer, etc. don't appear to. I'm sure some type without floating point supports it, though.

Regex...that's wat i'm afraid of...why do i have to do this in vb in the 1st place. Any recomendations for a good regex tutorial chris? Thanx for the reply by the way
Kampai!!!

The regular expression for a number is just ^\d+$
The best 'tutorial' is expresso, if you download that, you can test your regex in that. That's how I build mine.

You have to do this in ANY language. Unless your using a TextBox component specifically written to accept number but integers.

I am trying to apply different FontStyles to text within a RichtextBox control that was dynamically created. For some reason I do not get the .Selection??? anything Methods on a dynamically created control. All I have been able to successfully do is all or nothing. Here is the code I have been working with:
Try<br />
If tsbBold.Checked = False Then<br />
tsbBold.Checked = True<br />
For Each ctl As Control In TabControl1.SelectedTab.Controls<br />
If TypeOf ctl Is RichTextBox Then<br />
Dim selBold As New Font(ctl.Font, FontStyle.Bold)<br />
ctl.Font = selBold<br />
End If<br />
Next<br />
ElseIf tsbBold.Checked = True Then<br />
tsbBold.Checked = False<br />
For Each ctl As Control In TabControl1.SelectedTab.Controls<br />
If TypeOf ctl Is RichTextBox Then<br />
Dim selNotBold As New Font(ctl.Font, FontStyle.Regular)<br />
ctl.Font = selNotBold<br />
End If<br />
Next<br />
End If<br />
Catch ex As Exception<br />
MessageBox.Show(MsgBoxStyle.Exclamation, "An error has occured. Please try your selection again")<br />
End Try
Any suggestions?
Thanks,

Nevermind I figured out a way to work around it by using the following code.
Try<br />
If tsbBold.Checked = False Then<br />
tsbBold.Checked = True<br />
For Each ctl As Control In TabControl1.SelectedTab.Controls<br />
If TypeOf ctl Is RichTextBox Then<br />
Dim rtb As RichTextBox<br />
rtb = ctl<br />
Dim selBold As New Font(rtb.Font, FontStyle.Bold)<br />
rtb.SelectionFont = selBold<br />
End If<br />
Next<br />
ElseIf tsbBold.Checked = True Then<br />
tsbBold.Checked = False<br />
For Each ctl As Control In TabControl1.SelectedTab.Controls<br />
If TypeOf ctl Is RichTextBox Then<br />
Dim rtb As RichTextBox<br />
rtb = ctl<br />
Dim selNotBold As New Font(rtb.Font, FontStyle.Regular)<br />
rtb.SelectionFont = selNotBold<br />
End If<br />
Next<br />
End If<br />
Catch ex As Exception<br />
MessageBox.Show(MsgBoxStyle.Exclamation, "An error has occured. Please try your selection again")<br />
End Try
If there is a better or easier way please let me know.

Public Sub doDelete()
' MDI Main Delete record requ3est toolbar button pressed
'if no records are displayed on the grid exist then exit
Dim ConnectionString As String = System.Configuration.ConfigurationSettings.AppSettings("FinSolMainDBConn")
Dim connfinsol As New System.Data.SqlClient.SqlConnection(ConnectionString)
Dim myCommand As New SqlCommand("stp_DelTransOverride ", connfinsol)
myCommand.CommandType = CommandType.StoredProcedure
'Add Parameters
' 1 Policy Number
myCommand.Parameters.Add("@Policy_Nbr", SqlDbType.VarChar, 7).Value = PolicyNumber
' 2 Original Tranaction Override
myCommand.Parameters.Add("@Trans_CodeOrig", SqlDbType.VarChar, 6).Value = TransCodeOrig
' 3 Transaction Effective Date
myCommand.Parameters.Add("@Trans_Eff_Date", SqlDbType.DateTime, 8).Value = TransEffDate
' 8 Modified UID
myCommand.Parameters.Add("@ModifiedUID", SqlDbType.NVarChar, 48).Value = ModifiedUID
'Open Connection
Try
'Open Connection
connfinsol.Open()
myCommand.ExecuteNonQuery()
MsgBox("Data Deleted Successfully !", MsgBoxStyle.Information, Me.Text)
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Critical, Me.Text)
Finally
If myCommand.Connection.State = ConnectionState.Open Then
myCommand.Connection.Close()
End If
End Try
End Sub
I am not sure where to go, which DoDelete do go with.
Any help would be appreciated.
