<a href="http://www.download-registry-cleaners.com">Registry cleaners</a> scan the PC registry and delete outdated entries that are not in use anymore and remove faulty uninstall process. Moreover also detect and remove the embedded keys that are generated in the registry by malware programs like Trojans, viruses and spyware etc.

re: OrElse and AndAlso

Regarding array declaration:

I agree that the array declarations "adding" an element is confusing at first. I was writing a serial communication program and the extra element was screwing things up.

I believe the reason they did it is because then you can use either 1-based arrays or 0-based arrays easily. That means all us 0-based people have to remember to declare the array with the index of the last element in parentheses, rather than the size.

Regarding AndAlso and OrElse:

I recently discovered these, after I wrote a whole program with And's and Or's everywhere. I don't think they are fully interchangeable. There are some situations where AndAlso is essential. For example:

If listbox.SelectedItem <> nothing AndAlso listbox.SelectedItem.ToString = "the item"

is an absolute must if you have Option Strict turned on, because if you don't, this will generate an exception if the first test is omitted or AndAlso is replaced with And (because you'll get a null reference exception on the "ToString")

Listbox behavior, in this respect, is quite annoying. If you start using AndAlso and OrElse from the beginning, you avoid a lot of problems like these if you suddenly switch to Strict = On (like I did).

Until .Net arrived I always wrote short-circuit'd code statements.

I would take the original example;
If myInteger=4 And myString=“Hello” then
CallFunction()
End If

And write;
If myInteger=4 Then
If myString=“Hello” then
CallFunction()
End If
End If

It always resulted in better performing code.

I am personally not a fan of the DAAB.

Oops....a little typo:

Function should read:

Public Function gfToIIfOrNotToIIf(bAllBranchesOKToExecute As Boolean, bResourceAvailabilityHigh As Boolean, bReadabilityNotAnIssue As Boolean, bSoonToHandOffProject As Boolean) As String
gfToIIfOrNotToIIf = IIf(bAllBranchesOKToExecute, "Use IIf", IIf(bResourceAvailabilityHigh, "Use IIf", IIf(bReadabilityNotAnIssue, "Use IIf", IIf(bSoonToHandOffProject, "Use IIf", "Use If..Then..Else block"))))
End Function
