I am just starting .Net development (C#) and have come across some code that has me slightly confused....
If I have
Form myForm = new Form();
What does the following line actually do:
Application.Run(myForm);
Does it essentially do the same thing as myForm.ShowDialog() or myForm.Show() (that's what I thought, when running a form will do).....
I always find that the msdn is a poor resource for properly explaining material to new comers
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
Quote from wikipedia: "A successor to the programming language B, C was originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973 to construct utilities running on Unix." The creators want that everyone "see" his language. So he named it "C".
C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C.
Application.Run(myForm);
makes that form visible to user. It is the first form which get loaded in memory. And it runs this form in a message loop, so that you get all user events.
Short Answer:
Application.Run begins running a standard application message loop on the current thread.
Long Answer:
Application.Run
causes the windows application enters the message loop within Winmain to process various windows messages the OS posts to a message queue.The message loop, "Loops" until its receives a WM_QUIT message. It uses GetMessage
and PeekMessage
to retrive messages and PostMessage
to sent the retrived messages to Windows procedure.
If you do
Form myForm = new Form();
myForm.Show();
it will show the form and exit out. You will use new Form()
& .Show()
when you want to launch a new form from existing form.
