.net - What Is This Pattern Called
Sep 8, 2009Private someSub()
If someBoolean = True Then Exit Sub
' do some great work because someBoolean is False
End Sub
I know there is a name for this. The idea is to check something and if it isn't what you want then you stop code processing. I thought it was called "escape pattern", but Google isn't confirming that name.

Jul 5, 2010I am working on creating a customized UI composite control. This control would be a container to several other custom controls.As a first step, i am creating the container UI using a singleton pattern. This is because at any point in time only one isntance of this container is allowed to be created. This is fine.Now i want to practice interface based desgin. So i introduced a sinple interface calleD IdesignSurface which has two properties.

View 19 RepliesRegEx Pattern For Names?
Feb 21, 2012I was considering validating some input using RegEx to match a pattern of
Firstname, Lastname
I largely have it, but there is so much variability in names that I'm not quite sure if any pattern is safe. In fact, in this case, I know that no pattern is safe, so I have built in a means for the user to accept whatever was entered, regardless of what it was, which isn't so great.
What I'm wondering is whether or not there is a safe Regex pattern that will cover names in this format, or will cover at least most of them. What I currently have is:
"^[A-Z][a-z]+, [A-Z][a-z]+"
But that will allow through things like Hiker, Shaggy, the, which is fairly silly, but shouldn't be allowed....I think. Does anybody use names with commas in them? I know that apostrophes are fairly common, though I'm pretty sure I can ignore them.
