Timer does not fire during Send operation?

I have a timer that fires every 1/10 of a second and updates a label on a form. It works fine, but when the following code is executed:

    Dim oHTTP As New MSXML2.XMLHTTP
    ...
    oHTTP.send (DataToSend)

my VB6 program "looses program control" to the "send" operation for about 15 seconds. In other words, my timer event does not fire during the "send" operation. Is there any way to cause my timer to continue to fire at its interval during the "send" operation?

This is IDE behavior. Just compile your app and everything will be OK. Or use SetTimer API

Hi lee88,

You could also use DoEvents with the CCRP timer:

Cheers!

Ark: I compiled, but no change. I will try SetTimer API.

Here is an example

'=======Module=========
Public Declare Function SetTimer& Lib "user32" (ByVal hwnd&, ByVal nIDEvent&, ByVal uElapse&, ByVal lpTimerFunc&)
Public Declare Function KillTimer& Lib "user32" (ByVal hwnd&, ByVal nIDEvent&)

Public Const MY_TIMER_MSG As Long = &H5000& 'Any value, but try to avoid standard qindows MSG values
Dim m_hWnd As Long

Public Sub TimerProc(ByVal hwnd&, ByVal uMsg&, ByVal idEvent&, ByVal dwTime&)
    'Your staff here (like in Timer1_Timer)
    'Even Call MyForm.Timer1_Timer
End Sub

Public Sub EnableTimer(Optional ByVal hwnd as Long, Optional ByVal TimerInterval As Long = 1000) 'TimerInterval in millisec
    m_hWnd=hWnd
    SetTimer hWnd, MY_TIMER_MSG, TimerInterval, AddressOf TimerProc
End Sub

Public Sub DisableTimer()
   KillTimer m_hWnd, MY_TIMER_MSG
End Sub

'Now just call
EnableTimer Me.hWnd, 500
'From your form
'Important! Don't forget to disable timer in Form_Unload event!
