DOCUMENT:Q194861 11-FEB-2002 [visualc] TITLE :FIX: "AtlReportError: no overloaded function takes X parameters" PRODUCT :Microsoft C Compiler PROD/VER::3.0,6.0 OPER/SYS: KEYWORDS:kberrmsg kbVC600bug kbATL300bug kbGrpDSMFCATL kbNoUpdate ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - The Microsoft Active Template Library (ATL) 3.0, used with: - Microsoft Visual C++, 32-bit Enterprise Edition, version 6.0 - Microsoft Visual C++, 32-bit Professional Edition, version 6.0 - Microsoft Visual C++, 32-bit Learning Edition, version 6.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Porting an ATL 2.x project to ATL 3.0 might give you the following compilation error: error C2661: 'AtlReportError' : no overloaded function takes 2 parameters. CAUSE ===== AtlReportError() does not have any default parameters in ATL 3.0. AtlReportError() in ATL 2.1 did have default parameters. RESOLUTION ========== Specify all the parameters required by AtlReportError() or complete the following steps: 1. Use the CComCoClass static member Error() which accepts default arguments. For example, replace: return AtlReportError( CLSID_PolyCtl, _T("Must have between 3&100 sides")); with: // If your class is derived from CComCoClass: return Error(_T("Must must have between 3 & 100 sides")); // If not derived from CComCoClass<>: return CComCoClass::Error( _T("Must must have between 3 & 100 sides")); 2. Modify \vc98\atl\include\atlcom.h so that all the function prototypes for AtlReportError() accept default arguments. Essentially use the same prototypes used in ATL 2.1. The following code lists the various prototypes of AtlReportError and their default argument equivalents in the same order as AtlCom.h: - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, UINT nID, const IID& iid, HRESULT hRes, HINSTANCE hInst) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, UINT nID, const IID& iid = GUID_NULL, HRESULT hRes = 0, HINSTANCE hInst = _Module.GetResourceInstance()) - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, UINT nID, DWORD dwHelpID, LPCOLESTR lpszHelpFile, const IID& iid, HRESULT hRes, HINSTANCE hInst) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, UINT nID, DWORD dwHelpID, LPCOLESTR lpszHelpFile, const IID& iid = GUID_NULL, HRESULT hRes = 0, HINSTANCE hInst = _Module.GetResourceInstance()) - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCSTR lpszDesc, DWORD dwHelpID, LPCSTR lpszHelpFile, const IID& iid, HRESULT hRes) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCSTR lpszDesc, DWORD dwHelpID, LPCSTR lpszHelpFile, const IID& iid = GUID_NULL, HRESULT hRes = 0) - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCSTR lpszDesc, const IID& iid, HRESULT hRes) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCSTR lpszDesc, const IID& iid = GUID_NULL, HRESULT hRes = 0) - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCOLESTR lpszDesc, const IID& iid, HRESULT hRes) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCOLESTR lpszDesc, const IID& iid = GUID_NULL, HRESULT hRes = 0) - Replace: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCOLESTR lpszDesc, DWORD dwHelpID,LPCOLESTR lpszHelpFile, const IID& iid, HRESULT hRes) with: inline HRESULT WINAPI AtlReportError(const CLSID& clsid, LPCOLESTR lpszDesc, DWORD dwHelpID, LPCOLESTR lpszHelpFile, const IID& iid = GUID_NULL, HRESULT hRes = 0) STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
