bye for today.
try to map the bounds of the town to the bounds of the rectangle on your screen.
then take the digital data that is set of longitudes and latitudes from ge for some of the roads,
i mean take a sample at each road turning,
put them sequentially in a file,
convert them into pix data,
scale them to the square on your screen,
plot lines from one point to other.
now u will see the map that u have extracted from ge.
now you should be able to plot the value you have received from ur usb gps device.
all the best
bye.

sorry my friend,
i really have no idea on the format, which you are using.
here, in this thread, we were discussing on creating our own map format and our own map tool.
to solve your, problem, you may have to go through the api provided by the map tool which you are using.
first let me know, what tool you are using?
good luck.

your question is clearly not understandable.
as far as i understood,
you might want to convert x : 1 9 1 1 6 1 to 45°46'47.16"
if this is what you want to convert,
then, apply a reverse formula you should get it.
any problem in getting that, then i can help you.

Hi,
We have a BitMap with 60*60 size and at runtime i need to shrink the bitmap(image should be very sharp) based on the resolution of the system...and also is it possible to change the color of the bitmap like background ie(we need to change the color because we are using bitmap for buttons in a dialogbox ...so that if there is only one bitmap we can use that by changing background so that it can be used as disabled button..or a mouse hover button...)
You may use my DLL [^] to shrink the bitmap (however, unfortunately, it doesn't provide the background feature you need).

you can try with _findfirst and _findnext,
call them in proper recursive function and achieve your task.
