Why do the calculator output record box has a problem?

}

CodePudding user response:

Recond. SetSel (lastLine + 1, lastLine + 2, 0).
Recond. ReplaceSel (STR);//

Estimation problem is in the two sentences.
Look on the debugging, SetSel was based on the characters of the unit.

CodePudding user response:

If it is process input in the edit box enter messages, overloading dialog OnOK processing,

CodePudding user response:

Int lastLine=recond. LineIndex (recond. GetLineCount () + 1);//GetLineCount returns text unit lines
Recond. SetSel (lastLine + 1, lastLine + 2, 0).

Serial number to obtain an estimated problem, recond. GetLineCount () to obtain the index should be SetSel serial number inside, why + 1?

CodePudding user response:

LineIndex ()
Recond. SetSel (lastLine + 1, lastLine + 2, 0).
Recond. ReplaceSel (STR);//
These three functions are get for a few days didn't understand what you mean

CodePudding user response:

Int lastLine=recond. LineIndex (recond. GetLineCount () + 1);//the last character
Recond. SetSel (lastLine + 1, lastLine + 2, 0).//select the last character
Recond. ReplaceSel (STR);//replace the last character

CodePudding user response:

Additional code:
Int nStartChar nEndChar;
GetEditCtrl (.) GetSel (nStartChar nEndChar);//the last
GetEditCtrl (.) SetSel (nEndChar nEndChar);//select the last
GetEditCtrl (.) ReplaceSel (prompt);//replace the

CodePudding user response:

SetSel (lastLine + 1, lastLine + 2, 0) is why add a add 2 here

CodePudding user response:

Try 6 buildings code may be a bug
