In my system I have a problem with common dialog

Unread post by fred malack »

If commondialogs::tryGet_string(This, txt_input, "" , string::concat("does" , Patient, "have a fever(y/n) ?"))= "y" then
Assert(symptom(Patient, "fever"))


In the above code it popup and whenevr I click cancel it doesnt respond I need some help.

If you cancel this dialog then commondialogs::tryGet_string fails and the procedure won't be continued by askNextQuestion().

If you respond with anything else than "y" and confirm the dialog then the program
1. executes if,
2. jumps to askNextQuestion().

I think the solution is

Code: Select all

predicates diagnose(string Patient) -> string determ.   askFirstQuestion(string Patient) -> boolean Answer1 procedure. askNextQuestion(string Patient) -> boolean Answer2 procedure. clauses askFirstQuestion(Patient)=true :- Answer1=commondialogs::tryGet_string(This, txt_input, "" , string::concat("does" , Patient, "have a fever(y/n) ?")), Answer1="y", asserta(symptom(Patient, "fever")), !. askFirstQuestion(Patient)=false.   askNextQuestion(Patient)=true :- Answer2=commondialogs::tryGet_string(This, txt_input, "" , string::concat("does" , Patient, "have rashes(y/n) ?")), Answer2="y", asserta(symptom(Patient, "meningitis")), !. askNextQuestion(Patient)=false. % Calling sequence diagnose(Patient) = Disease :-      true=askFirstQuestion(Patient),            Answer2=askNextQuestion(Patient),      fail. diagnose(Patient) = Disease :-      symptom(Patient,Disease).  
Lesson
Forget if ...endif structures. These are not PROLOG but imported alien elements.


Other remarks:
"Y", "yes", "yeah", "39 centigrade" answers mean 'false' with your tools.
I do not want to complicate the program with retaining only the lowercased first character and repeating the question if the result is neither "y" nor "n".
The assertA() causes that "meningitis" precedes "fever" in the database of symptoms.
The assertZ() causes that "meningitis" follows "fever" in the database of symptoms.

This is an untested approach you might consider:

Code: Select all

class facts     finding : ( string ClinicalSignOrSymptom ).   class predicates     ask_put_finding : ( window, string, string ) determ (i,i,i).     ask_signs_and_symptoms : ( window, string Patient ) . clauses ask_put_finding( ParentWin, Pt, SignSymptom ) :-     Prompt = string::format( "Does % have a % (y/n) ?", Pt, SignSymptom ),     Response = commonDialogs::tryGet_string( ParentWin, Pt, Prompt ),     FC = string::frontChar( Response ),     if _Pos = string::search( "TY", YesOther, string::caseInsensitive ) then         assert( symptom( Pt, SignSymptom ))     else         % do nothing, but you could add more logic here later     end if.     finding( "fever" ). finding( "rash" ). finding( "headache" ). /*     Add other conditions to findings here.     Can you guess how you might be able to "consult" your findings from a file     into your expert system when you use a fact database? */   ask_signs_and_symptoms( ParentWin, Pt ):-     finding( SignSymptom ),  % for each clinical finding in facts         ask_put_finding( ParentWin, Pt, SignSymptom ),         fail. ask_signs_and_symptoms(_,_):-     vpiCommonDialogs::note("Patient Signs & Symptoms","Data entry is complete.").

Code: Select all

ask_put_finding( ParentWin, Pt, SignSymptom ) :-     Prompt = string::format( "Does % have a % (y/n) ?", Pt, SignSymptom ),     Response = commonDialogs::tryGet_string( ParentWin, Pt, Prompt ),     FC = string::frontChar( Response ),     if _Pos = string::search( "TY", YesOther, string::caseInsensitive ) then         assert( symptom( Pt, SignSymptom ))     else         % do nothing, but you could add more logic here later     end if.
Hi,

Good News:
1: Harrison Pratt's above code makes a case-insensitive comparison.
2: It solves the problem of "Y", "yes", ... and accepts words beginning with "T" as "y" answer.

Bad News:
1: If the user cancels the common dialog then the program does not execute the

Code: Select all

else         % do nothing, but you could add more logic here later
branch.
2: If the user presses the [Enter] immediately without a "y" character the the
Response will be an empty string and

Code: Select all

FC =string::frontChar( Response )
causes a runtime error.
TIA, Regards,
Frank Nagy

With the code u introduce to me.
I did post the code that i am using above and i am trying to change it with this
Method but its not workn please i need help.

I think this is what you need (if I understand the question correctly):

Code: Select all

predicates    onPushButtonClick : button :clickResponder.   clauses     onPushButtonClick(_sources) = button :defaultAction() :-         Fname = fname_ctl:getText(),         Mname = mname_ctl:getText(),         person::addPerson(Fname , Mname),         person::saveDatabase,         fname_ctl:setText(""),         mname_ctl:setText("").
