Syntax
'Declaration
Public NotInheritable Class ExcelLocale1033Proxy
'Usage
You do not need to declare an instance of a static class in order to access its members.
public static class ExcelLocale1033Proxy
public ref class ExcelLocale1033Proxy abstract sealed
public final class ExcelLocale1033Proxy
Remarks
By default, Visual Studio Tools for Office solutions for Excel are not affected by the end user's locale settings, and always behave as though the locale is English (United States). This behavior is controlled by the ExcelLocale1033Attribute.
You can use the Unwrap and Wrap methods of the ExcelLocale1033Proxy class to modify this behavior for specific Excel objects (that is, for objects of types that are defined in the Microsoft.Office.Interop.Excel namespace). For more information, see Formatting Data in Excel with Various Regional Settings.
Excel 2003
For Excel 2003, there are some cases where native Excel objects do not work correctly while the ExcelLocale1033Attribute is true. The methods of the ExcelLocale1033Proxy class can be used to work around these limitations. For more information, see Formatting Data in Excel with Various Regional Settings.
Excel 2007
For Excel 2007, native Excel objects work as expected when the ExcelLocale1033Attribute is true. Therefore, the methods in the ExcelLocale1033Proxy class are obsolete in the version of the Visual Studio Tools for Office runtime that is used by Excel 2007 solutions (the Microsoft Visual Studio Tools for the Microsoft Office system (version 3.0 Runtime)). For more information about the Visual Studio Tools for Office runtime, see Visual Studio Tools for Office Runtime Overview.
Performance
Because the Visual Studio Tools for Office runtime wraps all native Excel objects in a proxy object when the ExcelLocale1033Attribute is true, you might notice a slowdown in certain operations that involve native Excel objects. In these cases, you can improve the performance by using the Unwrap method to get the Excel object without the proxy, and then perform the operation using that object. If you do this, be aware that the object returned by Unwrap uses the locale ID of the current thread, not locale ID 1033.
