Re: CMS - setStringProperty() max length
I've run this a couple times, definitely something odd there, looks like
the message gets marshaled and sent but the broker never acknowledges
having received it, its possible we are messing up the marshaled data,
we will need to investigate this one further.

Ignore this message - looks like I had created a CRL project.

I tried looking at this and got the most recent build to compile...but I
had problems finding app_pools.h which is included in the APR release.
So I installed that, built it, and added the include directory to my VS
project.
Now I get a lot of unresolved symbols similar to this...

Look at the project settings we use in our own VC project files to build
and link the example program.

I am a newbie to CMS and Visual Studio and was seeing if there was a
guide to getting this up and running. I downloaded the libraries, but
if I want to create a new app and just reference these libraries how
would I do that?
Thanks of the information

The difference essentially lies in the way the string length is encoded
for the string properties verses the content of a message itself. The
content of the message allows for four bytes to define the length but
the string properties only allow for two, so its basically short vs int.

I really appreciate you looking into this problem, and fixing it, getting
the max up to 65k.
I'm curious why the behavior for StringProperties is different than for the
text of the TextMessage itself (65k vs 2gb)? Is it just set somewhere as
the max length? Or are they handled differently?
Is this an architecture limit that I need to account for in my
implementation?
