RE: Enumerating Block Contents (xAP Framework.NET)

["Sullivan, Glenn" <gsullivan@xxxxxxxxxxxxxx>]

Perfect, thank you...

So I have a service that logs to my MSDE database... But to get it to
work, I had to create a user account for it to run under, since MSDE
installs with Windows Authentication Only as it's default.

Do you think I need to automate the "create a user" part of this?
 I
can, through the service installation routine, but the way I look at it,
anyone who can set up MSDE and actually access a datasource that they
have created probably has the brains to know how to create a user, no?

That's an interesting question. This probably isn't as ideal or
obvious as it perhaps might be.

The answer is that both the message block object (of class
xAPMessageBlock) and a header (derived from class xAPHeaderBase)
inherit from DictionaryBase.

Thus you can foreach all the DictionaryEntry's in the block or header.
So to iterate the block contents (this is in C# rather than VB, sorry)

foreach (DictionaryEntry entry in event_args.Message.Body)
{
String keyword = (String)entry.Key;
xAPPairValue pair_value = (xAPPairValue)entry.Value;
}

This gives you the pair keyword and the pair value (which will either
be a xAPASCIIValue object if it's a plain "Name=Value" entry in
the
message, or a xAPBinaryValue).

Obtaining the value text from 'pair_value' is simple via the Value
property on the xAPPairValue object.

Sadly not I'm afraid. There's only message_block["PairName"]
which
returns the value part, and only when it's a "Name=Value" pair
(ASCII
vs Binary), it seems too. Hmmm.

I'll sort something out for the next release.

HTH,
