New GPSDriver library

It would appear I spoke to soon, it works as the old GPS.dll on the desktop, but is still wrong on the device.

It seems to be the same on the device as the desktop for me and it's hard to see how it could be different, are you sure you copied the correct GPS.dll to the device? Nevertheless it is still wrong at -6 degree longitude intervals i.e -6, -12, -18 ... Looks like the implementation of Fix needs a tweak! This is how VB .NET does it.

public static double Fix(double Number)
{
    if (Number >= 0.0)
    {
        return Math.Floor(Number);
    }
    return -Math.Floor(-Number);
}

I have replaced the GPS.DLL converter object with the GPSDriver.DLL converter object

Then I feed the WGS84LatLonToUTM function 51.115180, -114.095520 on the desktop I get 11 U 703283 5666646
on the device I get 10 U 1122746 5700438

Both gave the smae results using the converter object in the GPS.DLL

I should of course had said "are you sure you copied the correct GPSDriver.dll to the device?" in my previous post

I've just tried your data and I get the same correct result on both desktop and device for the old GPS.dll and the new (but still faulty) GPSDriver.dll. Are you really really sure you don't have the old GPSDriver.dll on the device as that incorrect result is what the original GPSConverter produces.

@agraham, You are right of course. My solution didn't work correctly with whole numbers.
I've updated the file in the first post.

@bish0p, please download the updated file in the first post.
I guess that you've previously tested on the device a compiled application which used the source code of the older library.
Now after you'll update the source code (cs file) as well, the problem should be solved.

Your right the .cs file had not been updated.

Hello,

I'm testing your demo app and it appears an error like 'Error getting device state'
Error number 87.

Do you have any ideas?

Regards.

Are you working with an internal GPS?
Try to comment this line and see if GetGPSDate works.

Hi Erel,

Yes it's internal an HTC 3300.

And I can't see the GetGPSDate as a property.
