IT COMPILES!!! I've spent a lot of time over the last several days reading every article Google yielded on c++ member functions and pointers. I still don't understand references and pointers, but I looked at me code last night and the solution just came to me. That's the way I learn I guess. I just need some time to absorb what I have read.

Anyway, I was reading thru the UDMS class, getting ready to just put everything into one huge file under one class, when I got to UDMS::ProspectDetailTab. It dawned on me that I wouldn't be able to point to Popups::member. I would need to point to a UDMS::member, then call Popups::member from there.

Came up with this solution:
main.h:

#ifndef main_main_h
#define main_main_h

#incluce <CtrlLib/CtrlLib.h>

using namespace upp;

#include "Popups.h" //has to come after "using namespace upp"
struct UDMS : TopWindow
{
private:
    // a bunch of declarations 

    void CallToPopupsClass(); // new wrapper function
public:
    typedef UDMS CLASSNAME;
    UDMS();
    Popups pop;
};
#endif

main.cpp

#include "main.h"
// a lot of code that will eventually be moved
// to another function

void CallToPopupsClass(); // new wrapper function
{   pop.QNHelpPopup();
    return;
};

void ProspectDetailTab();
{   detail.QNHelpButton.WhenAction = THISBACK(CallToPopupsClass);
};

Thanks, cbpporter, for your insight. I've removed all references to UDMS from Popups. The circular dependency was preventing me from getting to the real problem: what I was trying to do just can't directly be done in c++. I'm working on figuring out a more dynamic way to call Popups class. Haven't gotten that far yet. Probably end up with a more dynamic inline function for my wrapper. I don't want 30 wrappers to Popups::members in main.cpp.

I think I understand what pointers and references are, but I'm having trouble with the when, where and why.

Next issue: try as I might, I'm having trouble with \n in a String. The newline sequence seems to be completely ignored. It's not showing up in the code, but it's also not resulting in a newline. I also tried crating my own popup window for this task with the same result.

String helpTxt= " CCI - Customer Called IN \n"
	" RMC - Returned my Call \n"
	"  NA - No Answer \n"
	"DC1,2,3,w - Phone 1,2,3,work Disconnected \n"
	"LM1,2,3,w  - Left Message on phone 1,2,3,work \n"
	"APPT - Set Appointment \(open appointment popup\) \n"
	"  AC - Appointment Confirmed \n"
	"  NS - Didn't Show for Appointment \n"
	"KEPT - Kept Appointment \n"
	"  NN - Enter New Note \n"
	"Find - Open Find Prospect Popup";
	
	//qnhelp.DoneButton.WhenAction = THISBACK(CallToStub); */
	
	PromptOK(helpTxt);

The above code results in:

Quote:

CCI - Customer Called IN RMC - Returned my Call NA - No Answer DC1,2,3,w - Phone 1,2,3,work Disconnected LM1,2,3,w - Left Message on phone 1,2,3,work APPT - Set Appointment (open appointment popup) AC - Appointment Confirmed NS - Didn't Show for Appointment KEPT - Kept Appointment NN - Enter New Note Find - Open Find Prospect Popup

Should look like:

Quote:

CCI - Customer Called IN
RMC - Returned my Call
NA - No Answer DC1,2,3,w -
Phone 1,2,3,work Disconnected
LM1,2,3,w - Left Message on phone 1,2,3,work
APPT - Set Appointment (open appointment popup)
AC - Appointment Confirmed
NS - Didn't Show for Appointment
KEPT - Kept Appointment
NN - Enter New Note
Find - Open Find Prospect Popup

Where di I go wrong?
