C++ Network Tables

[IDKnow]

I am attempting to use the network tables class to pass values from my SmartDashboard extensions to the robot.

This thread describes the process using Java

but it seems to imply near the end that the same process will not work for C++

In my code and in the windows API I could find equivalent commands though- for everything other than begin and end transaction.

Without these, the robot crashes as soon an i try TableName->GetNumber("",0);

Am I missing something?

//declarations:
NetworkTable *Vision;
float d;
//initialization
Vision->GetTable("VisionTable");//should create table if does not exist
//control loop (where it crashes)
if (Vision->IsConnected())
{
     //Vision->beginTransaction();
     d = Vision->GetNumber("d",0);//where 0 is default if "d" does not exist
     //Vision->endTransaction();
}
