Get and Set Private Properties using Reflection in C#

It's frustrating when you're using an API and some properties you requuire are set as private. This certainly was the case when attempting to resume a video using the YouTube V3 API the other day.

Here is a code snippet on how to set private properties using Reflection.
Code Snippet
  1. private static void SetPrivateProperty<T>(Object obj, string propertyName, object value)
  2. {
  3. var propertyInfo = typeof(T).GetProperty(propertyName, System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
  4. if (propertyInfo == null) return;
  5. propertyInfo.SetValue(obj, value, null);
  6. }
  7. private static object GetPrivateProperty<T>(Object obj, string propertyName)
  8. {
  9. if (obj == null) return null;
  10. var propertyInfo = typeof(T).GetProperty(propertyName, System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
  11. return propertyInfo == null ? null : propertyInfo.GetValue(obj, null);
  12. }

MsgBox - A Better Winforms MessageBox in C#

Introduction

MsgBox is an enhanced solution to the in-built MessageBox class. It's designed so that the styles, features and behaviour mimic the in-built control with added features.

MsgBox allows a better Messagebox experience by allowing the following features:
- Do not display this message again
- Custom font styles and font colors
- Scrollbars for text which is too long

Using the code

MsgBox is used like a standard MessageBox object. There is a different return object which encapsulates the original DialogResult. This handles extra information which as whether the user clicked 'Do no display this message again'.

 

Simple Example

Code Snippet
  1. MsgBox.Show(this, &quot;Hello&quot;, &quot;Caption Text&quot;, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);
End of Code Snippet

 

Custom Fonts

Code Snippet
  1. MsgBox.Show(this, &quot;Hello&quot;, &quot;Caption Text&quot;, MessageBoxButtons.OK, MessageBoxIcon.Information, true, new Font(&quot;Verdana&quot;, 12f, FontStyle.Bold), Color.Red);
End of Code Snippet

 

Long Text

Code Snippet
  1. MsgBox.Show(this, &quot;Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello&quot;, &quot;Caption Text&quot;, MessageBoxButtons.OK, MessageBoxIcon.Information, true, new Font(&quot;Verdana&quot;, 40f, FontStyle.Bold), Color.Blue);
End of Code Snippet

 

Handling the do not display message again checkbox

Code Snippet
  1. DialogResultNew res = MsgBox.Show(this, &quot;Hello&quot;, &quot;Caption Text&quot;, MessageBoxButtons.OK);
  2. if (res.DoNotDisplayMessageAgain) // Do something here
End of Code Snippet

YouTube Comments and Commenting with YouTube API V3 (Google.Apis.YouTube.v3)



Google deprecated V2 of the YouTube API over a year ago, but as of last month, the URLs have been taken offline; forcing users to upgrade to V3 of the API. One of the last features requiring implementating on the V3 platform was the ability to comment on channels and videos. The following example shows how to leave a top level comment on a channel or video using V3 of the API with C#

Example
Code Snippet
  1.  
  2. YouTubeService youtube; // Init your service here - Make sure you include the new required scope: YouTubeService.Scope.YoutubeForceSsl
  3.  
  4. CommentThreadSnippet commentThreadSnippet = new CommentThreadSnippet();
  5. //commentThreadSnippet.ChannelId; Comment on a channel - leave video id blank if so
  6. commentThreadSnippet.VideoId = v.ID; // Comment on a Video by VideoID
  7.  
  8. // A top level comment is a new comment (Not a reply to an existing comment)
  9. commentThreadSnippet.TopLevelComment = new Comment() { Snippet = new CommentSnippet() { TextOriginal = comment }};
  10.  
  11. // Make an insert request and get result snippet
  12. CommentThreadsResource.InsertRequest commentReq = youtube.CommentThreads.Insert(new CommentThread() { Snippet = commentThreadSnippet}, "snippet");
  13. CommentThread commentRes = commentReq.Execute();
End of Code Snippet

Silently Delete a File within a Windows Batch File (BAT File)

I have recently been preparing some custom install scripts lately and I found a few things that may prove to be of some use! This script deletes a file silently and will not report the result in the console window.

Code Snippet
  1. @echo off
  2. del /s randomtextfile.txt >nul 2>&1 REM Delete file silently
End of Code Snippet

How to get operating system 32bit or 64bit from a Windows Batch File (BAT File)

I have recently been preparing some custom install scripts lately and I found a few things that may prove to be of some use! This script uses a registry key to determine weather the host system is a 32bit or a 64bit system

Code Snippet
  1. @echo off REM Hide output from commands
  2. @echo Attempting to get operating system type (32bit or 64bit)...
  3.  
  4. REM -------------- Get 32bit or 64bit --------------
  5. Set RegQry=HKLM\Hardware\Description\System\CentralProcessor\0
  6. REG.exe Query %RegQry% > checkOS.txt
  7. Find /i "x86" < CheckOS.txt > StringCheck.txt
  8.  
  9. If %ERRORLEVEL% == 0 (
  10.     @echo This is 32 Bit Operating system!
  11.     SET ostype = "32bit"
  12. ) ELSE (
  13.     @echo This is 64 Bit Operating System!
  14.     SET ostype = "64bit"
  15. )
  16. del /s checkOS.txt >nul 2>&1 REM Clean up silently

Getting and Setting File Tag Meta Information in C# and ASP.NET - With TagLib and DsoFile Examples

The Problem
I recently developed a video content management system, and rather than store hidden files to track versioning and movement of physical files, I wanted to modify the internal file meta information of the videos themselves. I planned to stuff a database ID into the comment tag within each video file, but this proved to be very challenging given the very disoraganised way in which various operating system handled different file types.

Possible Solutions
MediaInfo - http://sourceforge.net/projects/mediainfo/. Cool API, updated a lot, but there is no support for setting file meta information. The entire API is READ ONLY!

TagLib - https://taglib.github.io/. Again, good API with scope to set file tag meta information. So I decided to try this API out and see how far I could get with it. I started hitting it's limits when I couldn't set file meta information for a LOT of video file types: MKV, MOV, 3GP, ASF and more.

DsoFile - http://support.microsoft.com/en-gb/kb/224351. Microsoft's answer to tagging Microsoft Office file tag information. It's able to set Office file tags but also totally new custom properties within each file. You cannot see these values in Windows Explorer without a handy Powershell script plugin, but it works for ALL file types, not just office documents. It's written in C++ and includes the source code also. The downside is that it's a COM component, 32bit and no longer supported. However, somebody compiled a 64bit version here

The Ideal Solution
DsoFile seems like a great solution to the problem. TagLib works hard to achieve an ideal solution, but there are too many file types out there ever changing and the library finds it hard to keep up. I decided to use DsoFile for my project for the time being. I have provided some sample code below so you can see how TagLib and DsoFile libraries modify file meta tag information.
