In every programming language, when you want to loop through a collection, you use the 'for' loop in maximum scenarios. When writing code in Visual Studio, you might be aware that, there exist a code snippet to write the for-loop structure.
But you might not noticed that, there exist another code snippet to generate a reverse for-loop. Let's see what it is and how it operates.
Visual Studio 2017 version 15.3, has been released, along with .NET Core 2.0 and Visual Studio for Mac (version 7.1) operating system. Microsoft, in a blog post, announced the availability of both the products. Visual Studio 2017 version 15.3 contains many new improvements and fixes.
.NET Core 2.0 is the second major version of .NET Core and this release focuses on performance improvements and expanded set of APIs available via .NET Standard 2.0.
If you are using COM components on your .NET code, you might be already aware of the Marshal.ReleaseComObject and Marshal.FinalReleaseComObject, which are used to release the managed reference to Runtime Callable Wrapper (RCW) of the COM object.
If both are used to release COM objects from memory, and you are unsure which one to use, then this post will help you to learn the differences between the calls.
.NET Framework 4.7.1 is the next version of the .NET Framework, which is going to ship with Windows 10 Fall Creators Update. Microsoft, in a blog post, announced the availability of 'Early Access Preview Build' of .NET Framework 4.7.1.
It's now a feature complete build and running under testing phase. If you are a Windows Insider, you can start validating your applications running on the latest version.
If you are using COM objects like Microsoft Excel or Microsoft PowerPoint, you may sometime notice that the COM instances are not releasing from the process list; even though you called Close(), Quit() on the application instance.
In case you faced the same issue, this post will guide you to find the Process ID (from the HWND) of that particular instance to take further action to release it.
If you are using .NET Framework 2.0 or .NET Framework 3.5, and getting unexpected Runtime Error while repeatedly calling the System.Net.NetworkInformation.Ping.Send method from C# code, this is due to an issue which got resolved in .NET Framework 4.0 and above.
Today, we are going to discuss about the issue, the root cause and the workaround to resolve this issue targeting .NET Framework version older than 4.0.
It's often require to parse a string value to another data type, like integer, and there exists a confusion among the developers whether to use the Parse method or the TryParse method that the framework provides to us.
In this post, we will discuss the difference between each of those two methods and guide you to understand and pick the preferable one. Continue reading to know more.
Let's continue our 'Back to Basics' series. It's often an interview question to get an idea of the basic knowledge of a candidate. This is one of the simple question that an interviewer may ask during an interview and you should also know this while writing your code.
In this post, we are again going to discuss on the basics and this time we will learn the difference between null string and empty string.
StringCollection class is a spcialized collection type present in .NET Framework class libraries. The name itself represents it as a collection of strings. It exposes common methods and properties to manage string collection.
If you do not know about this class, in this post we are going learn about it's properties, methods and learn how to use it.
In last few articles we have discussed about NPOI libraries for .NET. There could be some cases, while reading Excel files, you may get an exception with 'The supplied spreadsheet seems to be Excel 5.0/7.0 (BIFF5) format. POI only supports BIFF8 format' as message.
In this quick tip, we are going to discuss about this issue, the way to handle it and the way to read the same Excel workbook content.
In the last two articles, we have learned how to use the NPOI library to read Excel 2007 (.xlsx) and Excel 97-2003 (.xls) file format. We have also discussed more about the APIs and shared the code snippet for you to understand it easily.
In this article, we will learn how to read Excel 95 and older workbooks easily using the free Apache NPOI libraries in your C#/.NET applications.
In the last article, we have discussed about the NPOI library and then learned how to read Excel 2007 file formats using the free, open sourced NPOI library. I hope, the code snippet was clear and easy to understand.
In this article, we will learn how to read Excel 97-2003 workbooks easily using the free Apache NPOI libraries in your C#/.NET applications.
Recently, we have learned how to read Excel workbooks using the Microsoft Office COM APIs. As you may already know that the COM APIs are slow while performing operation, we will see another way to read the content which is faster.
In this article, we will learn how to read Excel 2007 workbooks using the Apache NPOI libraries which is available freely to use in your application.
You would like to build an application/addin that reads outlook mail and notify the user or would like to do some other operations based on your business need. For this, you will need to use the Microsoft Outlook APIs.
Today we are going to see, how this can be done using the Microsoft.Office.Interop.Outlook.dll to read the email from Outlook context and extract the data.
Along with Visual Studio 2017, Microsoft also released the .NET Core Tools 1.0, which are supported on Windows, Mac and Linux operating systems to build cross-platform applications. Though it is part of the Visual Studio 2017 installer, but you can also download them separately.
In this post, sharing the links to download the .NET Core SDK and .NET Core Runtime for different environment for easy access.
Microsoft released the final version of Visual Studio 2017 and is currently available for download. This release brings a new lightweight and modular installation experience, that you will really love. This also brings a lot of new features to accelerate your development productivity.
Find the links below to download the latest version of the Visual Studio 2017, an IDE which every developer must need.
Recently we learnt how to read Microsoft Word and Microsoft Excel document contents (text only) using the interop APIs exposed by Microsoft. Now, what about reading the text content from PowerPoint slides? This can be achievable using another interop assembly file.
Today we will discuss how to extract the texts available in PPT files using 'Microsoft.Office.Interop.PowerPoint.dll'. Code has been shared for your easy reference.
Recently, we learned how to read text contents of Microsoft Word document from a .NET application using the APIs exposed in 'Microsoft.Office.Interop.Word.dll'. There may be a business requirement to read contents of Excel sheets too.
Today we are going to learn how to read Microsoft Excel documents. The complete source code has been shared for your easy reference.
There could be some possible business needs for your .NET application to read the text contents from a Microsoft Word document. This can be simply done using the APIs exposed in the dll named 'Microsoft.Office.Interop.Word.dll'.
Let's have a quick look on how to do it using C#/.NET. Also find the complete source code shared here for your easy reference.
Recently in a blog post, we discussed, how to detect whether an assembly is digitally signed using the C# programming language and System.Management.Automation.dll from Microsoft. That was one way to get the status of the digital signing.
Today we will learn another method to detect the same without using any additional dll references in our project. I hope that, it will much more interesting to learn.
