How to get started with mobile app?

Are you new to mobile development and wondering where to get started in this saturated and complex world of frameworks? Are you wondering whether to go native, hybrid or new kid on the block: PWA? I would suggest don't waste any time and just get your hands dirty....

When I started looking at mobile development, I went through the same experience. So to save you the time, I would suggest start with Ionic framework to start building Hybrid apps. You should be comfortable with HTML, JavaScript, some CSS and some Angular (SPA framework) knowledge would help but you can learn this as you go along.

You can get started with Ionic in 3 simple steps.

You can test you app locally in your browser or on your device using DevApp

That's all you need to get started!!! Your career as mobile developer started in under 10 mins!! Happy development.

Feel free to share any more similar frameworks in comments below.

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...
