After having converted a whole lot of training materials based on VB. However, the poetry wouldn’t work in C#, because – unforgivably – it’s a c ASe-Se NSit Iv E language. Before I start ranting, let me just acknowledge that case-sensitivity confers one (and only one) advantage – it makes it easier to name private and public properties: Both VB and C# contain a way of testing mutually exclusive possibilities, the Select Case and Switch clauses respectively. A Visual Basic Select Case clause, returning a description of how old someone is.
NET into C#, Andy ' Wise Owl' Brown decided to write a tongue-in-cheek rant whilst he could still remember the pain-points. The age range for a young person is a tad generous, reflecting the age of the author of this article.
The generated object which provides the code for setting up and managing the user interface.
Forms created with Qt Designer can be subclassed together with a standard QWidget-based class.
This approach makes all the user interface components defined in the form directly accessible within the scope of the subclass, and enables signal and slot connections to be made in the usual way with the connect() function.
We generally recommend this approach for libraries and large applications.

Note: You can use Qt Creator to create the Calculator Form project.
It automatically generates the main.cpp, UI, and files, which you can then modify.The generated code contains the form's user interface object.It is a C struct that contains: The generated code can be included in your application and used directly from it.However, componens created with Qt Designer often require close integration with the rest of the application code.For instance, the code provided above will compile and run, but the QSpin Box objects will not interact with the QLabel as we need a custom slot to carry out the add operation and display the result in the QLabel.Alternatively, you can use it to extend subclasses of standard widgets.
