Reye #1 / 6	Newbie, help with function that returns two strings Hi, sorry if this seems very stupid, I'm trying to create a function that returns two CStrings as result of the internal processing, I need to obtain fName and tName. CString CPag1::RealName(CString FieldName) { int x=FieldName.Find('.',0); int nRightLength=FieldName.GetLength()-x-1; CString fName=FieldName.Right(nRightLength); int nLeftLength=FieldName.GetLength()-nRightLength-1; CString tName=FieldName.Left(nLeftLength); return fName; return tName; Quote: } Thanks and best regards.

David Wilkinso #2 / 6	Newbie, help with function that returns two strings Reyes: No C/C++ function can return two values as you attempt. Pass a non-const referece parameter to get extra returns. Eg void GetTwoInts(int& i, int& j) { i=2; j=3; return; Quote: } The reference parameter is a C++ feature which is nicer to use than traditional C pointers.

Fabric #3 / 6	Newbie, help with function that returns two strings Hi, your question is not really MFC related, better see comp.lang.c or comp.lang.c++. Anyway you should do something like : void CPag1::RealName(CString FieldName, CString* pfName, CString* ptName) { int x=FieldName.Find('.',0); int nRightLength=FieldName.GetLength()-x-1; (pfName) =FieldName.Right(nRightLength); int nLeftLength=FieldName.GetLength()-nRightLength-1; (tName)=FieldName.Left(nLeftLength); Quote: } then call it by doing : CString FieldName=...; CString fName;CString tName; MyPag1.RealName(FieldName,&fName,&tName); Hope this helps Fabrice Quote: > Hi, sorry if this seems very stupid, I'm trying to create a function that > returns two CStrings as result of the internal processing, I need to obtain > fName and tName. > CString CPag1::RealName(CString FieldName) > { > int x=FieldName.Find('.',0); > int nRightLength=FieldName.GetLength()-x-1; > CString fName=FieldName.Right(nRightLength); > int nLeftLength=FieldName.GetLength()-nRightLength-1; > CString tName=FieldName.Left(nLeftLength); > return fName; > return tName; > } > Thanks and best regards.

How about a function that returns an object made up of the 2 strings. Sent via Deja.com http://www.deja.com/ Before you buy.

Coho #5 / 6	Newbie, help with function that returns two strings ...In that case you could use a pair std::pair< CString, CString > realName(CString& x); Or... How about a function that returns an array of two strings? CString* realName(CString& x); or std::vector< CString > realName(CString x); etc...

Richard Norma #6 / 6	Newbie, help with function that returns two strings You could also create the two strings in the calling function and pass references to them with your function: void CPag1::RealName(CString FieldName, CString &fName, CString &tName) { int x=FieldName.Find('.',0); int nRightLength=FieldName.GetLength()-x-1; fName=FieldName.Right(nRightLength); int nLeftLength=FieldName.GetLength()-nRightLength-1; tName=FieldName.Left(nLeftLength); Quote: } > > Hi, sorry if this seems very stupid, I'm trying to create a function > that > > returns two CStrings as result of the internal processing, I need to > obtain > > fName and tName. > > CString CPag1::RealName(CString FieldName) > > { > > int x=FieldName.Find('.',0); > > int nRightLength=FieldName.GetLength()-x-1; > > CString fName=FieldName.Right(nRightLength); > > int nLeftLength=FieldName.GetLength()-nRightLength-1; > > CString tName=FieldName.Left(nLeftLength); > > return fName; > > return tName; > > } > > Thanks and best regards. > How about a function that returns an object made up of the 2 strings. > Sent via Deja.com http://www.deja.com/ > Before you buy.
