Val() function in CFML puts uncompacted value upto
999999999999

==========

CF custom page
if you didn’t declare a var in a page & u call.. a custom page
inside that custom page you say
Caller.varname
[but that “varname” ins’t defined in the parent]
this is valid… & the advantage is that u can access that in the parent page [calling page] as
Variables.varname
even though that “varname” is not declared inside the parent page.

Avoid multiple Response.Write statements and group them in to few. Slower:

‘Add a default Select Word
Response.Write ” <option value=””0″”>(Select a Program Manager)</option>”

¨       Do While Not objRs.EOF
Response.Write ” <option value=” & objRs!ProjManKey & “>” & objRs!ProjMan & “</option>”
objRs.MoveNext
Loop
Response.Write “</font> </select>”

Faster:

Dim strHTML

‘Add a default Select Word
strHTML =  ” <option value=””0″”>(Select a Program Manager)</option>”

Do While Not objRs.EOF
strHTML = strHTML & ” <option value=” & objRs!ProjManKey & “>” & objRs!ProjMan & “</option>”
objRs.MoveNext
Loop
strHTML = strHTML &  “</font> </select>”

Response.Write strHTML

<script language=”VBScript” runat=”server”>

above seems to be executing at server AFTER the page is loaded.  So loading data before a page is loaded is not working..

<% %> this inline script seems t be loading BEFORE a page is loaded in a web browser.

If <%inline script%> used[Server.CreateObject], the connection object is created right away, while if <object> tag is inserted

<%…%>
<object ….
<%…%>
works, the object created by the <object> tag doesn’t get created until there is a use
ex.
if the object created using <object is a recordSet, then it is never created until
recordSet.Execute.. or similar happens

=========
if the object is created using Server.CreateObject inside a SUB or FUNCTION, then that object is never created until that SUB or FUNCTION is called.

======

<script language=”VBScript” runat=”server”>
tag wouldn’t execute unless it is explicitely called, as a FUNCTION or SUB

=======

If you Request.QueryString() a non-defined variable VBS automatically creates the variable and hence
IsEmpty() -> TRUE and IsNull() -> FALSE!

=================

If you Trim(Request.QueryString()) a non-defined variable, then VBS automatically creates it. Hence
IsEmpty() -> FALSE and
IsNull() -> FALSE

========

If you Request.Form(“”) a non-defined variable, then VBS outputs
IsEmpty() -> FALSE
IsNull() -> FALSE

If Trim(Request.Form(“”)) a non-defined variable then
IsEmpty() -> FALSE
IsNull() -> FALSE
