hi all,

i am using visual studio 2005 C++ to developing a pocket pc dialog.
But this error occur when i try to compile.
Error 1 error LNK2001: unresolved external symbol "public: void __cdecl CTryDlg::OnBnClickedBackBtn(void)" (?OnBnClickedBackBtn@CTryDlg@@QAAXXZ) AddTryDlg.obj


can anyone tell me what is the possible solution?

The solution is to make sure you coded that function with exactly the right parameters (in your case the function does not have any parameters). If there is a OnBnClickedBackBtn function make sure it contains the class scope CTryDlg::

(Been there and done that mistake too).

now you have the classes all screwed up. Of course CProfileDlg isn't a member of CGoDlg because its a different class. You made an error somewhere.
