"Web Part Error: Sandboxed code execution request failed. Co

Question

Hello,

I used Visual Studio 2012 to build a SharePoint 2013 solution including a very simple Visual Web Part. I deployed that solution into SharePoint Online (version 16.0.0.2016). When I ran the web part, i got an error message

"Web Part Error: Sandboxed code execution request failed. Correlation ID: xxx"

But when i try with the other solution (same source code), it runs well. It looks like, the SharePoint Online is NOT stable product.

How can I fix this problem? How can I know what exactly happened with very short error message and Correlation ID? Can I have a chance to view logs file of SharePoint Online?

Thanks,

Rajkiran

Unless I'm missing something here, I'd have thought that you should be able to create an XmlDocument and then use its LoadXml method to load the XML string you've received from the serial device without needing to save it to a file first.

You can then create an XPathNavigator by calling the XmlDocument's CreateNavigator method.

So, in code, that would be be something like this:

XmlDocument doc = new XmlDocument();
doc.LoadXml (xmlString);
XPathNavigator nav = doc.CreateNavigator();

Alternatively, you could forget about XPathNavigator and use LINQ to XML which can certainly parse in-memory XML strings.
