Regional Setting Decimal Seperator
<p>I have written a program intended only for users in the US and
UK.  However, one of my client install the Windows 7 Enterprise and Spanish Language OS .. So my program use comma as the decimal separator instead of decimal point , therefore my program get screwed up !!! </p>

<p>I try to fix it for him by changing back the regional setting in his machine to English (UK), however it's still not working !!! The program still use the comma as the decimal point !! </p>

<p>Any idea how should i fix it ?</p>
