I log some coördinates from GPS..

$GPGGA,062417,5111.8695,N,00425.7264,E,1,03,3.4,4. 8,M,47.1,M,,*4C

I extract the lat = 00425.7264
and lon = 5111.8695

I put in code :
Set wwLoc = mainMap.GetLocation(lat,lon)

And what do I get: Run-time error '-2147.......(8007....) : The parameter is incorrect..

What is it that I do wrong?

I don't know about your code, but I think you will need to convert to decimal format for MapPoint, that's what I use.

i.e. 5111.8695 N = 51.19783 N = latitude

You are in Antwerp, yes?

BTW u hav your lat and long reversed.

Oh yeah.. but it's correct in my code, sorry.

Indeed, I am in Antwerp..

So I have to convert to the decimal format... any idea how to do that in VB 6? cause I am very new to VB...

Many Tnx

Here's a function I wrote to do just that, you pass the value in GPS NMEA format and the function returns the decimal format.

Use like this assuming you have the NMEA value for lat in a string:-

lngDecimalLatitude = gpsConvert(strNMEAlatitude)

Use again for Long

Copy and paste into VB6 and it should look better when the colours are correct.



Private Function gpsConvert(ByVal sngTemp As Single) As Single ' converts GPS format to Infomap format
Dim intDegrees As Integer
intDegrees = Int(sngTemp / 100)
gpsConvert = intDegrees + (sngTemp - (intDegrees * 100)) / 60 ' sngTemp - (intdegrees * 100) removes the whole degrees,
'then devide by 60 to get decimals of a degree, then add the whole degrees back on to get degrees and decimals of a degree
End Function
