Outstanding, that took care of my issue!! Thank you very much for your assistance. Your DLL and Mr. Dowson's FSUIPC has let me take my Flight Sim exerpience to a whole new level, from just enjoying the flying to getting my hands dirty making a realistic sim to sit in. Outstanding work, my compliments to both of you guys.

Good afternoon everyone, I just want to start with I am not a programmer and I have read all documentation with the best of my comprehension abilities. I can't seem to identify a cause for my issue. I am writting a VB.NET application (yes it's a weak language but it is all that I know) that is basically updating some text fields with values from the autopilot. Here are some specifics: Microsoft FSX Using default aircraft - Cessna 172 WideFS Client connected to remote FSX system Latest version of FSUIPCClient.dll Here is the code behind a timer that is polling every 300ms: Private Sub Poll_Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Poll_Timer.Tick Dim airSpeed As Offset(Of Integer) = New FSUIPC.Offset(Of Integer)(&H2BC) Dim altAltitude As Offset(Of Integer) = New FSUIPC.Offset(Of Integer)(&H7D4) Dim altRate As Offset(Of Short) = New FSUIPC.Offset(Of Short)(&H7F2) Dim altHead As Offset(Of Short) = New FSUIPC.Offset(Of Short)(&H7CC) FSUIPCConnection.Process() Dim altALT As Double = (altAltitude.Value / 65536D) * 3.28084D Dim altHDG As Double = (altHead.Value / 65536D) * 360D Me.TxtAPALT.Text = altALT.ToString("f0") Me.TxtAPRate.Text = altRate.Value.ToString("f0") Me.TxtAPHDG.Text = altHDG.ToString("f0") End Sub This code works perfectly for a little while. It updates the fields and reports changes accurately and timely, I was pretty happy with it . . . until . . . it randomly gets the following error: FSUIPC Error #15: FSUIPC_ERR_SIZE. The amount of data requested exceeded the maximum allowed in one Process(). Can someone help me out with this? I would much rather have something fail consistently than to do it when every it feels like it. It makes it a whole lot harder to diagnose. I would think if I was requesting data that was out of bounds, it would do it from the get go. The error occurs even if the values remain static and could pop up after 10 seconds or 5 minutes. I fully expect to hear that I'm an idiot, need to read the docs, need to look here or there, but honestly that is where I started and it got me here. I appreciate any assistance anyone can offer. Thanks, Dave
