Mobile journey options


In the last few years, we have seen rise in the use of mobile devices. As more and more users are using mobile devices, there is an increasing demand for businesses to have presence in the mobile world. Mobile devices have created tremendous business opportunities. The term mobile is not limited to mobile phones anymore, but it includes any device which can be used to access the information on the move. This includes tablets, hand held game consoles, media devices, watches etc. This list is increasing every day. 

Options for mobile development

There are number of options for developing apps with mobile presence, but we will explore the following 3 most commonly used solutions.
  • Native apps: Native apps are downloaded and installed locally from platform specific marketplace.
  • Cross platform apps: Using cross platform framework, you can develop native or hybrid apps. Hybrid apps are browser based apps but the user experience is same as a native app.
  • Cross browser, mobile ready web application: These are web based applications which run under a browser on a mobile device.

Searching Unicode characters in Oracle table

Oracle implementation of Regular expression has no support for using hexadecimal code to search for Unicode characters. The only way to search for Unicode character is it use the character itself. Normally with Regular expression, you can use \x or \u followed by hexadecimal code to search for any character. E.g. \x20 will match space. But REGEXP_LIKE in Oracle does not support \x. You need to use unistr function to convert the code to equivalent character and then use it with REGEXP_LIKE. E.g. REGEXP_LIKE(source,'[' ||unistr('\0020')|| ']');

C# Performance Improvement - The Power of StringBuilder

 Often when we are wring code we don't think about performance and go with the default options available to achieve a task. String concatenation is one such scenario. If you are doing simple and few string catenations, then you can use the following result = string1 + string2; string1+= string2; result = String.Concat(string1,string2); String.Format and string interpolation are few other options.  However when you are performing large and repetitive  operation, string catenation can be expensive. Here is an example to prove the point.  As you can see it took 41 seconds to perform 100k string catenation. Now lets replace this with StringBuilder and see.  8 ms!!!!!! That is a massive performance difference. Hope you get the point. More info on StringBuilder can be found here https://learn.microsoft.com/en-us/dotnet/api/system.text.stringbuilder?view=net-7.0

System.Configuration in .Net Framework 2 onwards

Often application need custom configuration section. System.Configuration namespace includes classes for reading and writing configuration settings. There is a slight difference in how you use this namespace depending on the Framework version you are using Prior to .Net Framework 2.0, the .Net Framework included System.Configuration namespace, but that version of the namespace is now outdated. If you simply add the System.configuration namespace to your project (using in C#), your application references the outdated namespace. To refer to the updated namespace, follow these steps 1. In VS, open the project that requires System.Configuration namespace. 2. Click on the Project menu and then click Add Reference 3. On the .Net tab, Select System.Configuration as shown in following figure, and click OK 4. Now add the System.Configuration namespace to your project normally using Imports (in VB) or using (in C#) and your application will reference the correct version of the namespa...
