FirstWeekOfYear without getLocaleInfo

Sometimes it happens, that the function WinAPI::getLocaleInfo() raises an exception, when calling the Windows function GetLocaleInfoW in Kernel32.

While the function works for the GUI client, you get this exception in Enterpriseportal:

Dynamics Object Adapter Call failed.

Funktion 'GetLocaleInfoW' in DLL-Bibliothek 'KERNEL32' hat eine Ausnahmebedingung ausgelöst.

Microsoft.Dynamics.BusinessConnectorNet.XppException
at Microsoft.Dynamics.BusinessConnectorNet.AxaptaObject.Call(String methodName, Object[] paramList)
at Microsoft.Dynamics.Framework.BusinessConnector.Session.DynamicsObjectAdapter.Call(String methodName, Object param1)

The impact for the user was, that he just get a plain lookup popup window instead a calendar popup to select a date for a data field. *

I was unable to find the excact reason for that bug. But I assume it's the combination of x64 architecture, the .NET Business Connector and the use of a Unicode Windows Kernel function.

To bypass the error we've modified the method Global::firstWeekOfYear(), which was the caller to WinAPI::getLocaleInfo(), as follow:

Original:

static int firstWeekOfYear()
{
    #WinAPI
    return str2int(WinAPI::getLocaleInfo(#LOCALE_USER_DEFAULT, #LOCALE_FIRSTWEEKOFYEAR));
}

Modified:

static int firstWeekOfYear()
{
    /* #WinAPI
    return str2int(WinAPI::getLocaleInfo(#LOCALE_USER_DEFAULT, #LOCALE_FIRSTWEEKOFYEAR));
    */

    System.Globalization.DateTimeFormatInfo info = System.Globalization.DateTimeFormatInfo::get_CurrentInfo();
    System.Globalization.CalendarWeekRule rule = info.get_CalendarWeekRule();
    ;
    return(CLRInterop::getAnyTypeForObject(rule));
}

With this modification the Windows function GetLocaleInfoW in Kernel32 will not be direct used.
