Thread: memory address

I'm doing tests on a class I'm writing to deal with Carbon data field IO

My methods work perfectly to get the data as a CFStringRef

I then decided to write the method to get the data as a string.

in order to do this, I used the following code:

Code:

ostringstream strstrBuffer;

strstrBuffer<<getCFStringFieldData()<<flush;

return strstrBuffer.str();

this compiles, and the method calls were executed

I then needed to test that they were returning the right thing.

so I declared a string (test), set its value as getDataAsCppString() and executed a cout statement: cout<<test<<"\n";

the program ran and the memory address of test was printed out

how do I get the actual string to print out?

This is the source for the whole header file

	//class Constructor
	DataField(ControlID commid,WindowRef win){
	
		contID=commid;
		
		window=win;
		
	}//end DataField
	
	//Gets a CFString from the data field, takes no arguments, returns a CFStringRef
	CFStringRef getCFStringData(){
	
		GetControlByID(window,&contID,&conthan);
		
		GetControlData(conthan,0,kControlEditTextCFStringTag,sizeof(CFStringRef),&cfbuffer,&actualSize);
		
		return cfbuffer;
		
	}//end getCFStringData
	
	//Gets a c++ string from the data field, takes no arguments, returns a c++ string
	string getCppStringData(){
	
		cfbuffer=getCFStringData();
		
		strstrBuffer<<cfbuffer<<flush;
		
		return strstrBuffer.str();
		
	}//end getCppStringData
	
};//end class DataField

c'mon, someone has to know what the problem might be!
