Resources for Windows Application

  • Resources are created automatically by default by VS.Net for Windows forms. They can be plain text files for string resources or XML files for string and binary resources.
  • You can select language for each form and have different layout for each language.
  • This creates satiellite assemblies for each language which are used by runtime depending on the culture selected.
  • Each satellite assembly resides in a culture specific folder which uses ISO naming convention for e.g. for UK English it will be en-GB and for US English it would be en-US.
  • There is no code in the resource dll.
  • Main assembly will use resourse dll in sub directories e.g. en-GB\assemblyName.resources.dll.
  • You can add custom resources.
  • Naming convention for custom resource file [resourceType].[culture].resx. This way the culture specific custom resouce files will be compile in the satellite assemblies [undocumented feature].
  • Resouces files are deployed in \[culture] fodler for windows forms and \bin\[culture] folder for asp.net.
  • You can access culture specific resource using ResourceManager.GetResourceSet(cultureInfo)
  • If the resource manager can't find the specific culture resource, it will fall back to neutal resource. For e.g. en is neautral resource for en-US, en-GB or en-CA.
  • If resource manager can't find netural resouce it will fall back to invariant resouce which is located in main aseembley.
  • A resouce manager bases its resource lookup based on the current thread's UI culture.

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...
