WinRTError Object (JavaScript)

JavaScript - Internet Explorer 10

When a Windows Runtime call returns an HRESULT that indicates a failure, JavaScript converts it to a special Windows Runtime error. It is available only in Windows Store apps, when the Windows Runtime is available, as part of the global JavaScript namespace.

errorObj = new WinRTError();

Remarks

The WinRTError error type is used only for errors that originate in Windows Runtime APIs.

Example

The following example shows how a WinRTError is thrown and caught.

JavaScript

try {
            Windows.Storage.KnownFolders.documentsLibrary.createFileAsync("sample.txt");
        } catch (err) {
            var n = err;
        }

Methods

The WinRTError object has no methods.

Properties

The WinRTError object has the same properties as the Error Object (JavaScript) object.

Requirements

The WinRTError object is supported only in Windows Store apps, not in Internet Explorer.
