Hi there,
I'm thinking of using binascii.crc32 as a hash-function when I read in
the reference
http://www.python.org/doc/current/lib/module-binascii.html:
crc32( data)
Compute CRC-32, the 32-bit checksum of data, starting with an
initial crc. This is consistent with the ZIP file checksum.

I am converting a VB6 WebClass application to VB.Net. Used the VB upgrade
tool to do the conversion - and it left me a lot of little code things to
do. Did those code things and got my app to compile. Did a few other code
things to take advantage of .Net features not available in VB6.
When I start the application on my PC I get the error shown below. It seems
to me that the app initiation is failing before any app code is executed.

Hi All,
Does C++/STL have hashtable where I can do stuff like:
Hashtable h<int>;
h.store("one",1);
h.store("two",2);
and then later retrieve them like:

I have a class "Data" and I store Data pointers in an STL set. But I have
millions of inserts and many more lookups, and my profiler found that they
cost a lot of runtime.
Therefore, I want to substitute the set<Data*> with a hash_set<Data*>:
typedef hash_set<const Data*, hash<const Data*>, eqData> DataPointerHashSet;
// typedef set<Data*> DataPointerHashSet; // (see complete code below)
But it doesn't work! Everything is fine...

Hi Guys
I'm having trouble getting a value from a hash table based on a key that I have added
The key is the handle to a socket and the value is an instance of a class called SckClientHandler
Class SckClientHandler has a ClientSocket property which is a valid Socket object
Here I add to the hash table
_clientSocketHash.Add((int)objSckClientHandler.ClientSocket.Handle, objSckClientHandler
where objSckClientHandler is an instance of...

Many times we have a bunch of enums we have from either different enums or
the same enum that will have various numeric values assigned. Rarely will
there be collisions in numbering between the enums. These enums you might
imagine would be like OrderPrice=27, OrderQuantity=50, OrderSide=62. There
may be a lot of these. So normally what we would have to do is store these
in hash table so hashtable=value could be set with the value....

I would be grateful if someone had a minute or two to review my hash
table implementation. It's not yet commented but hopefully it's short
and idiomatic enough to be readable. Some of the code (i.e. the
get_hash function) is borrowed from various snippets I found on the
net. Thee free function could probably need some love. I have been
thinking about having a second linked list of all entries so that the
cost of freeing is in proportion to...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
