this is the code of the header file: #include class CPropertyList { public: CPropertyList(); virtual ~CPropertyList(); public: static CString fnGetADsProperty(int intArg); static CString fnGetADsProperty(CString cstrArg); static int fnGetIntProperty(CString cstrArg); static CString fnGetProperty(int intArg); static CString fnGetProperty(CString cstrArg); //Statische members static CArray cstraProperty; static CArray cstraADsProperty; static CArray intaProperty; }; this ist the error i get (for each CArray) PropertyList.obj : error LNK2001: Nichtaufgeloestes externes Symbol "public: static class CArray CPropertyList::cstraProperty" (?cstraProperty@CPropertyList@@2V?$CArray@VCString@@AAV1@@@A) any ideas? derhackler es ist wie es ist und es ist und es ist fürchterlich

CArray is the template class - so you need to provide template parameters! Like that: class CPropertyList { ... static CArray cstraProperty; static CArray cstraADsProperty; static CArray intaProperty; }; and your always must define static variables (the code above is the declaration only!): this code your should place out of class declaration! (most of us placing this in CPP file ;) : CArray CPropertyList::cstraProperty; .. the same for others static members. Hope it'll help. #include class CPropertyList { public: CPropertyList(); virtual ~CPropertyList(); public: static CString fnGetADsProperty(int intArg); static CString fnGetADsProperty(CString cstrArg); static int fnGetIntProperty(CString cstrArg); static CString fnGetProperty(int intArg); static CString fnGetProperty(CString cstrArg); //Statische members static CArray cstraProperty; static CArray cstraADsProperty; static CArray intaProperty; }; this ist the error i get (for each CArray) PropertyList.obj : error LNK2001: Nichtaufgeloestes externes Symbol "public: static class CArray CPropertyList::cstraProperty" (?cstraProperty@CPropertyList@@2V?$CArray@VCString@@AAV1@@@A) any ideas? derhackler Best regards, ----------- Igor Soukhov (Brainbench/Tekmetrics ID:50759) igor_soukhov@yahoo.com | ICQ:57404554 | http://siv.da.ru

ups. ther's something wrong with the forum code. it ignores the template parameters! :(( but i've specified the parameters like CArray[CString,CString&] (i use other brakets). so something else must be wrong.

i've seen it.:cool:

define the static members as I did in previouse post (some minuts ago ;) - it should help. Yes - I see the templates problem - is not a reason ! ;) Best regards, ----------- Igor Soukhov (Brainbench/Tekmetrics ID:50759) igor_soukhov@yahoo.com | ICQ:57404554 | http://siv.da.ru

ah!!! i see the problem. initializing the arrays is not a want - it's a must!! now my code compiles. thank you!!! es ist wie es ist und es ist fürchterlich!
