Re: MFC dll and exe porting to 64-bit

Sorry for not seeing that....

Here is the only function exported in dll

----------------------------------
void CUesOastplsubApp::CreateInstance(char* sDsn, char* lpszDriver, int
fRequest, char* szResPath)
{
    CDsnPropertyDlg dlg;

    INT_PTR nResponse = dlg.DoModal(sDsn, lpszDriver, fRequest, szResPath);
    if (nResponse == IDOK)
    {
        // TODO: Place code here to handle when the dialog is
        // dismissed with OK
    }
    else if (nResponse == IDCANCEL)
    {
        // TODO: Place code here to handle when the dialog is
        // dismissed with Cancel
    }
}
----------------------------------

Here is my test exe

---------------------------------
typedef void (WINAPI*CreateInstancePtr)(char*, char*, int, char*);

{
    HINSTANCE loadDll;
    loadDll = LoadLibrary("path\\to\\my.dll");

    if(loadDll == NULL)
        MessageBox("Load Dll NONOK !","Info",MB_OK);
    else
        MessageBox("Load Dll OK !","Info",MB_OK);

    //retrive the dll function
    CreateInstancePtr pCreateInstance;
    pCreateInstance =
(CreateInstancePtr)GetProcAddress(loadDll,"?CreateInstance@CSubApp@@QEAAXPEAD0_K0@Z");

    if(pCreateInstance == NULL)
        MessageBox("Dll Error - Fail to load function","Info",MB_OK);
    else
    {
        GetDlgItemText(IDC_EDITDSN, m_Dsn);

        //cast the CString to char*
        char temp[512];
        strcpy(temp,m_Dsn);

        pCreateInstance(temp, "ODBC Driver Name", ODBC_CONFIG_DSN,
"path\\to\\resource.dll");
    }
}

Thanks
