In case theres a new way....
There are a few places where (I think) there are missing end ifs.
Does every If need an End. I always thought so, but since I have found a few that apparently dont, but the page has no error, I'm not sure... |

elseif

if there was a missing end if, the page would not load, and you'd get an error message.
are you referring to things like this?
if x = 1 then Response.Write x |

Example 1
if x = 1 then y = 2 : Z = 3
Example 2
if x = 1 then
y = 2 : z = 3
end if
Example 3
if x = 1 then
y = 2
z = 3
end if
The three examples above will process equally. You can use : to have multiple statements on the same line. However it is good practice to write each statement on a separate line. |

Do multiple cases work this way too? Say, Case 1:2?

With Case statements, multiple cases can be separated by commas. (I'm pretty sure anyway.) Like this:
Select Case
Case 1,2
do something here
Case 3
do something else
End Select

Nikol is right (except for missing criteria for select case) and you can also do like...
Select case x
Case 0 : y = 0 : z = 0
Case 1 : y = 2 : z = 3
end select

Is there a way to close a database connection without the close statement? I'm asking because there have been instances when I try to close a connection in some code and I get an error telling me it's already closed when there are no other close statements in the code. Is there something in this situation that may be similiar to not requiring an end if?

Ideally the close DB statement should check to see if there is an open connection first before closing it. I've seen an example somewhere on one of the more popular ASP sites - can't remember now though  |

You can always check the status of connection by using the following code:
if myConn.State = 1 then myConn.Close

Imagine all the end ifs I could have saved 
How about this:
if y = abc then Response.Write "Hello"
is less or more server intensive than:
if y = abc then
Response.Write "Hello"
end if
I guess then unless theres an else you might as well use the first example above? |

Two things:
1) Using the end if's makes the code much easier to read and debug (if correctly indented)
2) I would imagine that the end if is 'assumed' in the first case - that is to say that the parsing engine will include it anyway. So I expect no time is saved in omitting it. |

Especially with IIS 5.x where the ASP pages are kept precompiled.
For me, the decision purely depends on context.
if strBlaBla="bla" then Response.Write "bla"
if strBlaBla2="bla2" then Response.Write "bla2"
if strBlaBla3="bla3" then Response.Write "bla3"
will be less readable if we use the other form:
if strBlaBla="bla" then
Response.Write "bla"
end if
if strBlaBla2="bla2" then
Response.Write "bla2"
end if
if strBlaBla3="bla3" then
Response.Write "bla3"
end if
