problem with inline keyword
-
I have a function in CDocument file which I declared inline. When I call it from CView class, the linker reports LNK2001 error. If it's not inline then it works fine. Does anyone know what might be the problem?

The function is a member function of derived CDocument class, and I use it to access protected member variable which I created. If it is used within CMyDoc then it's ok, but when I call it from CMyView then the linker reports that error. Here is a full text of the error msg:
MyVew.obj : error LNK2001: unresolved external symbol "public: bool __thiscall CMyDoc::IsButtonPressed(void)const " (?IsButtonPressed@CMyDoc@@QBE_NXZ) -

Is the code in the header file? The code for an inline function must be in a header file, because the code needs to be visible to every CPP file that calls the function. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- You cannot stop me with paramecium alone!

isn't the
inlinekeyword made for declaring a function inline, wherever the code is written ?

no it's not. the compiler has to know to sources to "convert" it to code that fits in the calling function! Don't try it, just do it! ;-)
