How to communicate with RR via COM/ActiveX?

Hi all,

I've read Guino's 'How to integrate your app with RR' FAQ:
http://www.mp3car.com/vbulletin/rr-faq/86680-how-do-i-integrate-my-application-with-rr.html

But as I'm only new to programming, I'm having a little trouble figuring out how to actually use my app to talk to RR using Method 3 - COM/ActiveX SDK.(The reason I chose this method is that it seems to be the preferred method for communicating with RR, according to Guino.)

I'm using VB6 to create the app, but I dont know where to put the

Set SDK = CreateObject("RoadRunner.SDK")

in order that I can then use commands like

SDK.Execute "PLAY"
SDK.Execute "LOAD;AUDIO_PLAYER.SKIN"
SDK.Execute "LOAD;AUDIO_PLAYER.SKIN", True
MYVAR = SDK.GetInfo("TRACKNAME")

within my code, to trigger certain events in RR.
If anyone could give me an example, or a link to somewhere where I could learn how, I would really appreciate it.

Cheers
Ice

-Create a new project
-Add a button and a label to the form
-double click on any empty spot of the form
-on the form_load add: Set SDK = CreateObject("RoadRunner.SDK")
-Scroll to the top of the form and add this as the first line: Dim SDK as object
-Close the code window
-Double click on the button and add this:
SDK.Execute "PLAY"
label1.caption = SDK.GetInfo("TRACKNAME")

run it and press the button -- it should play/pause and display the track info on the label. That's all.

I followed your instructions exactly Guino, but I get this error at compile/run.

-------------------------
Runtime Error '429':
ActiveX component can't create object
-------------------------

The compiler halts at: Set SDK = CreateObject("RoadRunner.SDK")

I think its not finding/recognising/liking "RoadRunner.SDK".

EDIT
*************************
I downloaded the latest version of RR (12 Nov 2006) and ran it. Then I recompiled the app and........ IT WORKED :D.


If I execute the App and RR isnt running, the app loads RR.
Is there anyway to prevent RR from being loaded when the app executes?
*************************

Where can I find a list of commands for SDK.Execute "____" and SDK.___ etc?

Thanks Guino!

You can execute any commands in skin commands.txt, you can read any label codes listed in the same file.

You can CHECK if RR is running using: if FindWindow("RoadRunner", vbnullstring) then ... in order to only run the createobject line when RR is already running. The createobject line will run RR automatically because RR can't execute commands or provide any information if it isn't running. Before you ask, you'll probably have to copy the declaration of findwindow from apistuff.bas (in RR's source).

I'll stick with it auto-loading at the moment.
Thanks for your help dude!

Am i being a biffer or something? but i can only return zero's for:
Lat
Long
HDG
ALT
Speed

I can get the title and number of satalites

Here is what i have: (Its the most basic program...)

Code:

---

Dim SDK As Object
Dim GPS As Object

Private Sub Command1_Click()
SDK.Execute "PLAY"
Label1.Caption = SDK.GETInfo("TRACKNAME")
Label2.Caption = GPS.SATS
Label3.Caption = GPS.LAT
Label4.Caption = GPS.LON
Label5.Caption = GPS.HDG
Label11.Caption = GPS.Alt
Label12.Caption = GPS.Speed

End Sub

Private Sub Form_Load()
Set SDK = CreateObject("RoadRunner.SDK")
Set GPS = CreateObject("RoadRunner.GPS")
End Sub

Any ideas what im doing wrong. ive got Freedrive working and there is a route set and it definately gives me readings inside the GPS window.

I have tried a different skin and got the same
I have tried using MM intead of FD but then i dont even get the number of SATs.

Thanks in advance

You need to have RR connected to the GPS mouse not a 3rd party navigation program.

so there is no way to get it running through another navigation program? but RR doesnt have navigation built in, or does this mean i will need two GPS receivers.

1 for RR and 1 for FD - Sorry just a tad confused now

RR does not have navigation built in per se. It can read NMEA info from a GPS receiever and that is the information you are trying to pull in your app.

You don't need two GPS receivers, but will need a GPS port splitter. Do a search for GPS port splitter on the forum and you should have some info on them. Then just set the GPS Navigation to one virtual port and the set the GPS port in RRconfig to another.

Just got Xport 3 - Enforcer you rock :nw:
