An unexpected internal error occurred

Microsoft MapPoint

Hi,
I have a random problem not caused from the data. When i execute the
following code the program crashes with this error “4000 - unexpected
internal error occurred.”

ReDim arrayField(1 To 4, 1 To 2)
arrayField(1, 1) = 1
arrayField(1, 2) = geoFieldName
arrayField(2, 1) = 2
arrayField(2, 2) = geoFieldLatitude
arrayField(3, 1) = 3
arrayField(3, 2) = geoFieldLongitude
arrayField(4, 1) = 4
arrayField(4, 2) = geoFieldInformation
szconn = App.Path & "\customers" & sVehicleId & ".txt"
Set oDS = frmMain.map.ActiveMap.DataSets.ImportData(szconn,
arrayField, geoCountryItaly, geoDelimiterTab, geoImportFirstRowNotHeadings)
oDS.Name = "v" & sVehicleId
frmMain.map.ActiveMap.DataSets.Item("v" & sVehicleId).Symbol =
objSymbol
frmMain.map.ActiveMap.DataSets.Item("v" &
sVehicleId).SetFieldsVisibleInBalloon
Array(frmMain.map.ActiveMap.DataSets.Item("v" & sVehicleId).Fields(4))


The same code with the same data in other executions works perfectly :(
Help me please.
Hi CR,

Nothing obvious here. Perhaps a "-" or "." or carriage return/linefeed?
Perhaps, but if the problem is due to a special character then the problem
should happen anytime, but it is not therefore.

CR,

What is the value of szconn when this happens?
