F forisco Member Licensed User Nov 13, 2007 #1 Hi, if i write this : lat = GPS.latitude gradi = SubString(lat,0,2) minuti = SubString(lat,2,2) secondi = SubString(lat,5,4) secondi = (minuti*0.6-Int(minuti*0.6))*60+secondi*0.0036 i obtain the FormatException error : why?

specci48 Well-Known Member Licensed User Nov 13, 2007 #2 Hi forisco, gps.latitude has the format ddmm.mm So you should use: secondi = SubString(lat,5,2) Basic4ppc will not throw an error, if a SubString statement exceeds the original StrLength. specci48

specci48 Well-Known Member Licensed User Nov 13, 2007 #5 Do you get a correct latitude? What is the value of lat? If you a developing on the device you could use a MsgBox for debugging.

F forisco Member Licensed User Nov 13, 2007 #6 If i show only the lat variable, i obtain 4019.671835 The latitude is correct. The error is in the last line : secondi = (minuti*0.6-Int(minuti*0.6))*60+secondi*0.0036 and i obtain the same error if i use a calculation in an other line, for example : minuti = SubString(lat,2,2) * 0.6 It seem that b4ppc don't convert the SubString function in number...

F forisco Member Licensed User Nov 13, 2007 #7 I solved my problem thanks to an old answer of Erel (simply, the best)! When the GPS not send data, the gps.latitude variable is empty and i have my error! I must check if gps works (with the status property) and all work fine!!!! Wowwwwwwwww!!! :sign0136:
