small error
-
Hi all I have loaded (a copy just in case) of my project from VS2003 at VS 2005, it was converted fine with just a few errors that I fixed but I still have this one that I dont understand. I´m not an expert, I´ve few months programming MFC self learning and still a lot to learn. The error Line :
static CALLBACK CallbackProc(HWND hwnd, UINT msg, LPARAM lp, LPARAM lpData);The compiler error: error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Can I continue with my MFC project at VS2005 with no problems at all? Why I cant see my dialogs, main form , etc.. just the code? Where are they!!? thx in advance. Jdg--------------------------------------------- "Don't panic!. All will become clear in time" WYS Is Not always WYG

Modify this declaration to,
static int CALLBACK CallbackProc(HWND hwnd, UINT msg, LPARAM lp, LPARAM lpData);

They are in resource explorer. Aren't they ?

Done :) thanks. ups... sorry resource explorer! was hidden.. stupid me. =/ Well the previous part compiled ok, but I´m using too this code from MSDN by Paul DiLascia where he encapsulated SHBrowseForFolder in a class FolderDlg... http://msdn.microsoft.com/msdnmag/issues/05/06/CAtWork/default.aspx At VS2003 it was working ok... but now I´m having this fatal error... So my project still can´t compile :( please any help apretiated . thanks in advance.

Probably you are using
_DbgName, but linker is not getting its definition. In release build its definition is suppressed.jarleydg wrote:

Same case is with class
CInterfaceNames. Its for debug configuration only. In release confiruation, its defn's are suppressed, hence error.Prasad Notifier using ATL | Operator new[],delete[][^]

In fact it is in debug configuration where the linker errors came. When I compile in release, all is ok... So I´m missing something in my debug config? this line is a comment in the code // You must link shlwapi.lib for StrRetToBuf could this be the problem? If it is... how do I link shlwapi.lib ? thx again. jdg

Linking error are generated, because linker could not resolve certain function calls. From code of article you have mentioned,
_DbgNameis meant to compile in debug configuration(#ifdef _DEBUG) only. Can you show how you have used_DbgNamein your code ?jarleydg wrote:

No. It is already linked

I´m not using it, I just #include "FolderDlg.h" and use it this way :
BOOL CDlgEnsayoObs::BrowseForDataStore () { CCableOkApp* pApp = (CCableOkApp*)AfxGetApp(); CFolderDialog dlg(this); CString path; LPCITEMIDLIST pidl; BOOL bRet = FALSE; pidl = dlg.BrowseForFolder(_T("Seleccione el directorio de Almacén de datos"), BIF_USENEWUI |BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT ,NULL ,TRUE); path = dlg.GetPathName(pidl); if (path.IsEmpty ()) { return bRet; } else { pApp->m_sDataFilePath = path + "\\"; pApp->m_sDataStorePath = path + "\\"; SetDlgItemText(IDC_FILEPATH, "Seleccione un grupo de cables o Dir. de captura"); SetDlgItemText(IDC_DATASTORE, pApp->m_sDataStorePath); pApp->m_DataBase.SetDataStore(pApp->m_sDataStorePath); bRet = TRUE; } dlg.FreePIDL(pidl); // liberar PIDL cuando se termina--importante!! return bRet; }In my project is not _DbgName in any place. It´s only in the DiLascia code inside a debug.h file. I´m not including nor added to my project this two files, debug.h and debug.cpp. I´m only including FolderDlg.h, FolderDlg.cpp, where the functions I want to use are declared/implemented.
