    Carbon help

    I'm trying to develop a class to ease input from data fields in a carbon NIB reference.

    I set up the constructor, and everything worked perfectly.

    When I tried to add a method to read input from a text field, I started getting errors.

    The thing compiles, but the application shuts down and exits "with signal 6, SIGABRT"

    here's the code:

    Code:
    /*
     *  carbonGraphicIO.h
     *  
     *
     *  Created by Erik Schmidt on 3/25/05.
     *  Copyright 2005 Erik_Soft. All rights reserved.
     *
     *  Provides eased IO capability within text field in a carbon application
     *
     *  C++ version
     *
     */
    
    #include <Carbon/Carbon.h>
    #include <sstream>
    #include <string>
    #include <cstring>
    
    using namespace std;
    
    class DataField {
    private:
    
    	/*static ControlID ctrl;
    	static CFStringRef textBuffer;
    	static ostringstream textBufferConvert;*/
    
    public:
    
    	static ControlID ctrl;
    	static CFStringRef textBuffer;
    	static ostringstream textBufferConvert;
    
    	DataField(ControlID ctr){
    	
    		ctrl=ctr;
    		
    	}//end constructor
    	
    	pascal CFStringRef getCFStringData(WindowRef window){
    	
    		ControlHandle dataField;
    		
    		GetControlByID(window,&ctrl,&dataField);
    		
    		return CFSTR("void");
    		
    	}//end getCFStringData
    	
    };//end class DataField
    Code:

        // Create a Nib reference passing the name of the nib file (without the .nib extension)
        // CreateNibReference only searches into the application bundle.
        err = CreateNibReference(CFSTR("main"), &nibRef);
        require_noerr( err, CantGetNibRef );
        
        // Once the nib reference is created, set the menu bar. "MainMenu" is the name of the menu bar
        // object. This name is set in InterfaceBuilder when the nib is created.

        // The window was created hidden so show it.

        // Call the event loop

    	OSStatus err=eventNotHandledErr;
    	HICommand command;
    	
    	GetEventParameter(event,kEventParamDirectObject,typeHICommand,NULL,sizeof(HICommand),NULL,&command);
    	
    	switch(command.commandID){
    	
    		case 'tEst':
    		
    			TestCommand((WindowRef)userData);
    			
    			err=noErr;
    			
    			break;
    			
    		//end case
    		
    	}//end switch
    	
    	return err;
    	
    }//end CGIOMainWindowEventHAndler
    
    pascal void TestCommand(WindowRef window){
    
    	//cout<<"test\n";
    	
    }//end TestCommand
    Any ideas?
