P3Dv4 FSUIPCConnection.AirportsDatabase.Load() crashes

Capt. PERO

Recommended Posts

Hi gents,

I am using this function in VB.NET but on one client with P3Dv4 it crashed with "Index and length must refer to a location within the string. (Parameter 'length')"
The function I am using is

    If FSUIPCConnection.IsOpen = False Then
    End If
Catch ex As Exception
End Try

It is running great on other PCs with P3Dv5.

FSUIPCClient.dll Version

Any ideas?

Hi Peter,

The problem is going to be specific to your user's scenery (e.g. third party airports etc). Maybe one of the airports has a strange character in the name, or a missing runway number or something.

The easiest way to solve this is if I could get the MakeRunways output files from the user's computer. I could then run the load() here and see what's causing the problem. I'll be able to put a check or workaround in my code to stop it crashing.

I'll need:


If your user is not willing to send these to you then I'll come up with another plan.
