Hi All,

I have a non-ui running with a background worker that at various times during the day sends a Post to some software running on the same PC.

It gives an error on line 107 of the Lib.

Here is the i am using

Code for Strobe: 
Sub strobetoggle
    Log("strobe toggle")
    
Dim hjob As HttpJob
    hjob.Initialize("strobe",Me)
    hjob.PostString("http://192.168.0.230/RemoteCommands/SetOutputStrobeToggle","")
    If hjob.Success Then
        Log("Changed to Strobe")
        
    End If
    hjob.Release
End Sub

and this is the error

Waiting for debugger to connect...
