IMPLEMENT_DYNAMIC Error

Code : at .cpp file : IMPLEMENT_DYNAMIC(alb2CaptureOptionTree , COptionTree) //two .h file class COptionTree : public CWnd { .................... } class alb2CaptureOptionTree : public COptionTree { DECLARE_DYNAMIC(alb2CaptureOptionTree) .......... } Error : when compiling the code , Errors occur . error C2039: 'classCOptionTree' : is not a member of 'COptionTree' error C2065: 'classCOptionTree' : undeclared identifier In fact , I never define a class named classCOptionTree. Why ? What's the reason? Thank you ! Fly as a bird

add DECLARE_DYNAMIC in base class also. In ur code add DECLARE_DYNAMIC(COptionTree) in class COptionTree, and add IMPLEMENT_DYNAMIC(COptionTree,CWnd)in the cpp file Naren VC++ programmer

check with the definition of IMPLEMENT_DYNAMIC. ultimately it will call the CRuntimeClass(base_class). Thats why u need to implement dynamic creattion inevery class in up heirarchy naren VC++ programmer

try by setting the correct lib paths. Is it linking successfully if u omit the DECLARE_DYNAMIC, IMPLEMENT_DYNAMIC?? naren VC++ programmer

Hello, The DELCARE_SomeThing {SERIAL, DYNAMIC and DYNCREATE} macros are used to implement some features provided by CObject. Some of these features are RTTI provided by MFC, serialization and dynamic creation using the RUNTIME_CLASS macro. If your class wants to use one or more of these features, it should be derived from a class that has these features. If you don't you'll get those errors you had. Read here[^] for more information about CObject and dynamic object support. Behind every great black man... ... is the police. - Conspiracy brother Blog[^]
