vb.net parse issue

[lancaster123]

Hi Guys

Im writing a application in VB.NET that gets the users coordinates from FS in DMS and then converts them to Decimal Degrees. The conversion is working fine the issue im having is when I parse out the coordinates string to convert.

here is my current code to parse out the coordinates:

'parse out the Lat N or S
            Dim lat_NS As String
            lat_NS = Mid(Lat_str, 1, 1)
            'parse out the Lat Degrees
            Dim lat_Deg As Double
            lat_Deg = Mid(Lat_str, 2, 3)
            'parse out the Lat Minutes
            Dim lat_Min As Double
            lat_Min = Mid(Lat_str, 7, 2)
            'parse out the Lat Seconds
            Dim lat_Sec As Double
            lat_Sec = Mid(Lat_str, 10, 2)

            'Get Lon in var
            Dim Lon_str As String
            Lon_str = txtLongitude.Text

            'parse out the Lat E or W
            Dim lon_EW As String
            lon_EW = Mid(Lon_str, 1, 1)
            'parse out the Lat Degrees
            Dim lon_Deg As Double
            lon_Deg = Mid(Lon_str, 2, 3)
            'parse out the Lat Minutes
            Dim lon_Min As Double
            lon_Min = Mid(Lon_str, 7, 2)
            'parse out the Lat Seconds
            Dim lon_Sec As Double
            lon_Sec = Mid(Lon_str, 10, 2)

but say for example my lat lon was N053° 02.64' W000° 22,03'

it would loose all the 0's so it would return N53° 2.64' W0° 22,3' and that could take to to a different place how can I tell it to keep the 0's in

Many Thanks
Scott

Not sure I understand your issue, but can you use the split function and work on each part by checking their length.

Dim LongArray() As String = txtLongitude.Text.Split(New Char() {" "c})
' LongArray(0) is Long degrees
' LongArray(1) is decimal minutes

' if LongArray(0).Length = 3 you have W0°
' if LongArray(0).Length = 4 you have W10° to W99
' if LongArray(0).Length = 5 you have W100° to 180

Thanks I have changed my code to get decimal degrees directly from FSX so it has solved the issue without having to parse all the coordinates now

Just to check Scott, are you suggesting that W0˚ and W000˚ are different? I see the problem with 22.3 vs 22.03 but fundamentally all the other elements seem identical to me.
I do have a bit of code to convert various formats of coordinates to radians if that might be of any help.
