Thread: sendMessage from a .Net App

No no, you're looking at it right.. and you can use sendmsg to trigger commands on your app.. but you could do that slightly different from the SDK.. for instance, instead of using "SENDMSG" you could use setvar.. and a single variable with your "command".. something like:

"SETVAR;ORBCMD;<COMMAND>" from RR ... then in your c# app you could have a loop/check every so often (i.e. 2-5 times per second for faster response) where you'd do this (VB6/Pseudo Code):

Code:

IF SDK.GetInfo("=$ORBCMD$") <> "" then
   ORBCMD = SDK.GetInfo("=$ORBCMD$")
   SDK.Execute("SETVAR;ORBCMD;")

   Select Case ORBCMD
        case "PLAY"
               ...
        case "AUDIO"
               ...
   End Select
End If

Also, nothing prevents you from using both interfaces at once (for whatever reason).

THAT helps a lot. I wasn't sure if there was an event that triggered on a message received, or if it was something i had to check for. I'll press on...

}

I'm not sure how this works... InvokeMember is a method of System.Type (i.e., SDKType), not Object. Type.InvokeMember returns an Object. is that what RRSCR is? if so, what is the object "o" in InvokeMember?

Yes sorry, you're right, when I 'translated' the code I got that wrong.. this is the updated code:

Code:

public void TestSDKDOTNET()
{
        System.Type SDKType = System.Type.GetTypeFromProgID("RoadRunned.SDK");
        object SDK = System.Activator.CreateInstance(SDKType);
        RRSCR = SDKType.InvokeMember("GetInfo", System.Reflection.BindingFlags.InvokeMethod, null, SDK, new object[] {"TRACKNAME"});
        SDKType.InvokeMember("Execute", System.Reflection.BindingFlags.InvokeMethod, null, SDK, new object[] {"EXIT"});
}

Please note the SDK object passed as a parameter to InvokeMember.

works. thanks!
