Is it possible to check for the existence of an element? I have a dynamic
page which may or may not have a <div> holding a bunch of thumbnails, and I
want a function to check for the existence of the <div>. Doing:
blah = getElementById("thumbnails");
Generates an error.... I was hoping it would just return false or
something... Is there a way of doing this?

I'm having a hard time checking existence of windows. The only thing I found on
this is page 224 of Rhino. Why is there no function to check this? Is there
a publication on this part of the protocol I can read as a newbie? Please can
someone make a suggestion one what to read or try?
Sincerely, Xeno

All right, since my previous idea (calling functions through a
wrapper) was apparently so awful no one could suggest any
improvements, I'll try a different tack. My end goal is to make
detecting and reporting script errors easy and painless. This could
be accomplished easily if window.onerror were ubiquitous, but it is
not. My new idea is to hack together something superficially
resembling C's assert() macro, perhaps something like

What's the proper technique for checking for the existence of an attribute
within a node?
Lets say I did a SelectSingleNode which returned this element:
<AnAddress city="San Francisco" state="CA" />
What's the best why of determining if the attribute zipcode exists in this
node? If I try accessing the attribute with code like:
ZipCode = myNode.Attributes("zipcode").Value

Hi,
I am having trouble checking the existence of a temporary table.
Neither of pg_tables or pg_class list the temporary tables.
Is there any way to get the list of temporary tables?
Thanks,

Does anyone have any coding rules they follow when doing argument checking?
When arguments fail during check, do you return from the call with an
ambiguous return value, or do you throw exceptions?

I have found a lot of material on removing duplicates from a list, but I
am trying to find the most efficient way to just check for the existence
of duplicates in a list. Here is the best I have come up with so far:
CheckList = for x in self.__XRList]
FilteredList = filter((lambda x:x != 0),CheckList)
if len(FilteredList) len(sets.Set(FilteredList)): return
False
The first statement pulls the slice out of a matrix I need to check.

Hi
How can I check for existence of a certain table by name in and access
database and if the table exists find the number of records in it?
I guess I can access this information by setting up a dataset for the
database but I am wondering if there is a quick way to find this.
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
