Internet: Do You And Your Website Have Credibility?

Do You And Your Website Have Credibility?

Written by Dean Phillips

I recently received an unsolicited e-mail from some company offering me their search engine optimization services for $199. Even though I had absolutely no interest in repparttar

offer, just out of curiosity, I tried clicking on repparttar 118600

URL they provided in their e-mail. The URL didn't work, so I decided to check out this company with repparttar 118601

various search engines.

Incredibly, they were nowhere to be found! I couldn't find them on Google, Yahoo, Dogpile, anywhere! That's because they didn't really exist. They never did. They were just another one of repparttar 118602 many prevalent e-mail scams out there.

The point is, even though I had zero interest in their offer, had I been interested, this company's credibility was totally shot, for two reasons: First of all, for spamming me and secondly for obviously being a scam at best.

Another time, I was surfing repparttar 118603 Internet, checking out different business opportunities to review for one of my clients, when I came across this company selling "turnkey" website packages for $1295 and up. As I was reading repparttar 118604 information about repparttar 118605 various packages they had to offer, I came across their various addresses and telephone numbers.

Again, after doing some checking, I discovered those addresses didn't even exist. In addition, repparttar 118606 company was based in Israel and repparttar 118607 only type of payment they would accept were wire transfers.

Anyway, there were more than enough red flags and alarm bells for me to get repparttar 118608 picture pretty quickly. This company was an obvious scam and I advised my client of that fact.

Virtual Methods & Polymorphism in C#

Written by Pawan Bangar

Virtual methods allow object oriented languages to express polymorphism.This means that a derived class can write a method with repparttar

same signature as a methd in its base class, and repparttar 118599

bas class will call repparttar 118600

derived class's method.By default in java, all methods are virtual.

In C# like c++, repparttar 118601 virtual keyword is needed to specify that a method should override a method (or implementaion an abstract method) of its base class.

Class B { public virtual void foo () {}

} ClassD : B { public override void foo () {} }

Attemting to override a non-virtual method will results in a compile-time error unless repparttar 118602 "new" keyword is added to repparttar 118603 declaration, indicating repparttar 118604 method is intentionally hiding repparttar 118605 base clas's method.

Class N : D { public new void foo () {} } N n = new N ();n.foo; // calls N's foo ((D)n).foo; // calls D's foo ((B)n).foo(); //calls D's foo
