Hi All,
Having a little issue with phi_prompt, at the bottom of the code under
void top_menu_function_5()
when I add line
int choice=yn_dialog(“Start now?”);
I get the following
Example_menu:200: error: stray '' in program
Example_menu:200: error: stray '' in program
My_Menu_1_0.cpp: In function 'void top_menu_function_5()':
Example_menu:200: error: 'u201cStart' was not declared in this scope
Code below, truncated to fit (9500 characters is not enough)
the error will be in the next post...

Any help appreciated.

Use yn_dialog("Start now?") instead of yn_dialog(“Start now?”). Use the right quotes.
That did the trick, thanks mkwired.
Liudr, I did a cut & past from your Phi_prompt documentation 20110523.pdf
Thanks again.

Hahaha! I was caught by the same problem of left and right double quotations. Did you copy paste code from my documentation? Please do that with the sample code instead

Yes I did, not any more...
I have another small request.
At the end of the
wait_on_escape(xx);
time I would like the menu to move down to the next item or if I "do some down stuff"
and when at the last menu item there is a,
int choice=yn_dialog("Start now?");
I would like to "do some down stuff" which would take me back to the first top menu item & not reply with a 1 or 0.
Is this possible?
Steve...
You can make a modification to do that. I planned for it but never got around to implement the feature.
The last part of the phi_prompt structure is this:
void (*update_function)(phi_prompt_struct *);
All you have to do to use it is to assign a function address to it and insert a line of code in wait_on_escape to call it before escaping. Give it a try.
