The name 'ViewData' does not exist in the current context

-
Good Evening!

In an application where I played the class diagram in visual studio by adding controller class, repository class, and service class, I encountered an error "The name 'ViewData' does not exist in the current context" in my HomeController.

This is weird since the controller references System.Web.Mvc. The solution is:

1. Copy the source code in the HomeController and transfer it in a textfile for backup.
2. Delete the original HomeController.
3. Add another HomeController class
4. paste the backup code from the textfile.

I guess this is a bug when using class diagrams in Visual Studio 2010.

Good day Gents! I was trying to update my Microsoft Teams status and was wondering if I can add or insert emoji. For editing or adding new teams status, only text fields are available and there's no emoji icon similar to writing a teams message. After googling for a few minutes, I found this link Emoji's in status which is a feature request in Microsoft Teams User's Voice Forum. So far this upgrade request only has thirty votes which is relatively small and may be considered a low priority for the product team to implement. Given the limitations at hand, I tried several approach including copying an emoji in a chat message which didn't work and later found a solution using Microsoft Outlook 365. First is to create a new email message in Microsoft Outlook and press (Window Key + .). The emoji dropdown control will appear. Next is to select the emoji that you wanted to add to Teams. Copy the emoji from the newly created email message template and paste that to Micr

Good Day Gents! During this free-time I started setting up Node.js on my machine as part of my career goals which is learning new frameworks in preparation for new projects. So the first thing I did was to install TypeScript language to get myself familiar with Angular 2+. After I finished setting up TypeScript, I then created a simple HelloWorld program and ran the application through Visual Studio Code using the "tsc: build - tsconfig.json" command. I encountered an error which says "The term 'tsc' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again." Below are the details on my machine and packages installed:   - Operating System: Windows 10 Pro   - Node.js: 14.16.0   - npm version: 6.14.11   - Typescript: 4.2.3 (using command: "npm install -g typescript") After doing some research and reading thr
