More Retro Goodness

I hadn't been born when either of these breakfast cereals debuted, yet I still get a kick out of the recent retro packaging for these two.

Setting Default Values in an Angular Reactive Form

-
Something I ran into a few months back was that Angular won't reset a FormControl back to its initial value if you call reset()  on the FormGroup unless that FormControl was created with nonNullable: true . Here's an example:   private createForms ( formBuilder : FormBuilder ) : void {     //For the initial values to be considered the *default* values, we need to specify nonNullable: true.     //There used to be a dedicated property for this, but they deprecated it.     this . searchForm = formBuilder . group < ISearchForm >({       adminYear : new FormControl < number >( null , { validators : Validators . required }),       admin : new FormControl < string >( 'All' , { nonNullable : true , validators : Validators . required }), //Validator is kind of pointless here, as there WILL always be a value       examName : new FormControl < string | null >( null ), ...

How to Get Norton Security Suite Firewall to Allow Remote Desktop Connections in Windows

I ran into an issue recently with RDP connections being blocked by the firewall in Norton Security Suite. I checked the traffic rules under Settings > Firewall > Traffic Rules  and found that it was enabled by default (and couldn't be edited): But during further research, I found  this page  on Norton's support site which discusses the different trust levels of networks and mentions that, for the Public trust level, "This setting also blocks remote desktop connections by default.". I checked my network's trust level, and sure enough, it was set to Public (I'm not sure how/why). (Sidebar: Notice in the screenshot above that allowing Remote Desktop for Public Networks is defaulted to Allow , though that rule is not active). Here's what my network trust level looks like now after changing the setting to Private (accessible under Settings > Firewall > General Settings > Network Trust ): After changing the network trust level t...

How to Determine if a Column Exists in a DataReader

-
I recently had to work on something which required me to query a database, open the results in a DataReader, and check for the existence of a particular column. While the DataReader doesn't have a method to do this, with just a few steps I was able to accomplish this task. Here's how. First, the DataReader has a method named GetSchemaTable() , which returns a DataTable consisting of information regarding the data contained in the DataReader. The first column in this DataTable is named ColumnName , and its value is (obviously) the name of the column. Knowing this, we can loop through the rows in the DataTable, checking the ColumnName column for a value that equals the name of the column we're looking for. To this end, I wrote a static method in one of my classes which takes the DataReader and the name of the column being sought: (C#) public static bool HasColumn(DbDataReader Reader, string ColumnName) {    foreach (DataRow row in Reader.GetSchemaTable().Rows)  ...

The Cause and Solution for the "System.Runtime.Serialization.InvalidDataContractException: Type 'System.Threading.Tasks.Task`1[YourTypeHere]' cannot be serialized." Exception

-

The other day I worked on some new code that ran fine locally, but when deployed to one of our internal web servers threw the following exception: "System.Runtime.Serialization.InvalidDataContractException: Type 'System.Threading.Tasks.Task`1[NameOfTheOffendingType]' cannot be serialized." This had me scratching my head -- after all, to use that old developer's saying, "it worked fine on my machine". Not only that, but the exception was occurring when I was calling a method that didn't use the type mentioned in the exception (according to the stack trace it looks like the exception was happening during one of the many calls made under the hood during the use of a proxy class method). But once I found the cause of the problem, it made total sense. In this case, I had added a new WCF service reference to the project, and the proxy class that was generated for it was including some new task-based asynchronous operations that are supported in .NET 4....

Loading an Image from an Embedded Resource in .NET

-
Disclaimer: The following information is for educational purposes only. Do not use to harass muppets. This is one of those things that I learned to do back when I first started learning .NET, but can never remember how to do when I need it, so I'm adding it here. Hopefully this will come in handy to someone. First, add an image to your project. You can do this by right-clicking on your project in the Solution Explorer and selecting Add->Add Existing Item , then browse for an image file using the dialog that appears. After the image has been added, click on it in the Solution Explorer and set its Build Action to Embedded Resource . Adding images to your project this way is useful for when you deploy your assembly -- it removes the need to distribute individual image files, instead embedding them into your assembly. Next, use the following line of code to load your image from the embedded resource (examples are given in both C# and VB.NET. Please note that the below examples...
