Preliminary Testers Wanted - GPS Tracker

**pRoFiT** · 10-01-2005, 12:06 AM

So is that a no on the multiple tracking shown in map software? i.e. to cars on the same map live?

Command line switches are super easy. I use them in GammaControl and NaviVoice.
If you want the source, you know who to contact

Switches at startup are fine, no issue at all as you say, what I'm not so sure about is deciding how to let users stop it from a command line as the primary exe would already be running so some communication would be needed. Although having said that it can't be that hard to have on app tell another to close.

I'm looking for some XML help... anyone used MSXML, ideally form within Delphi? I have my GPX output 95% working but it's putting a silly attribute in one of my tags for no apparent reason.

God that takes me back, remember in DOS (u know, the black screens seen in old movies) using 'drop files' to communicate, the controlling program created a file like 'c:\stop.txt' and the oher program checked to see if it existed, if it did then it deleted it and quit.

I used the old GPSTracker originally posted on the thread, and it generated an XML file. When I went to upload it to motionbased.com it gives me the error:

"The contents of the file is not recognized. "

Any ideas?!

Yes, the format is wrong.

I'm working on writing proper XML now but the MSXML control is doing some wacky stuff.

Well, the code I've got only allows one instnace, and if someone starts the program with a new command line, the command line gets sent to the running instance.

Yeh, XML can be a challenge

**ukchris** · 10-01-2005, 07:52 PM

That's neat, regarding the command line, how do you recveive the second command line in the running instance?

I think I have the XML issue sorted, bloody namespaces!

Chris.

Here's the code I use. Link
BTW: You know how to read/write/modify nested XML code? Like if you don't know were the XML file ends?

**ukchris** · 10-01-2005, 08:11 PM

Thanks for the link, I'll take a look once things progress that far.

As for XML my first foray just wrote it as text, which is easier but unreliable in many ways. Now I'm using MSXML which seems to basically manage the whole XML Document for me, I just add nodes similar to a TreeView and it closes all the tags automatically and maintains the whole structure.

I'm not sure if you're asking if I can help or telling me you know how..?
