Difference Between Int32.Parse, Convert.ToInt32, and Int32.TryParse – CodeProject

Posted by jpluimers on 2015/08/05

Every C#/VB/.NET developer should read Difference Between Int32.Parse, Convert.ToInt32, and Int32.TryParse – CodeProject.

Then also read TryParse with default values.

It is all about handling values that are not Integers, Overflow values and Nulls. There are subtle differences, in the handling of the methods, and the exceptions they could throw: ArgumentNullException, FormatException and OverflowException.

Finally read all about the NumberStyles enumeration, IFormatProvider interface and CultureInfo (especially the difference between InvariantCulture, CurrentCulture, CurrentUICulture and InstalledUICulture).

Because getting your conversions right matters.

Genymotion (formerly AndroVM) is an Android x86 virtual machine appliance (via: install in VMware Player/Workstation – YouTube)

Posted by jpluimers on 2014/02/14

Very interesting: Install AndroVM in VMware Player/Workstation – YouTube.

The successor is Genymotion “the faster Android emulator”, and seems to have an easier installation path: Run Android on Your Desktop With Genymotion Android Emulator.

One of the drawbacks of going native: the Delphi for Android compiler currently only generates ARM Android code, otherwise this would be a great way to test your apps.

But it works fine if you use Java, Oxygene for Java or MonoDroid: much faster than the emulator (which you cannot run in a VM at all).

There seems to be a way to install ARM translation, so I need to check that out: android – How to install google play service in the genymotion (ubuntu 13.04) .Currently it doesn’t have drag and drop suport – Stack Overflow.

[MonoDevelop] MonoDevelop and Xamarin Studio

Posted by jpluimers on 2013/04/16

Just in case you missed it too:

Xamarin Studio is MonoDevelop plus a set of add-ins. Those add-ins provide the required functionality for working with Android and iOS projects, and integrate some Xamarin services such as the Component Store.

The development of MonoDevelop will continue like it has been in the past. All the improvements which are not related to Xamarin’s commercial offerings will be done in MonoDevelop, and we have plans for a lot of them: code analysis, version control, debugger, etc. We are committed to keep evolving MonoDevelop, because a better MonoDevelop means a better Xamarin Studio.

MonoDevelop will also keep working on Linux. There may be some rough edges with MonoDevelop 4.0 on Linux, since for this release we put our focus on Mac and Windows, since that’s what Xamarin’s customers use. So if you find any problems please file bugs!
