WMI is definitely the way to go. You can get quite a bit of useful audit information through that API. |
Simplest solution? Don't let the browser cache at all. Append the current time (in ms) as a query.
(You are still in beta, so you could make a reasonable case for not optimizing for performance. But YMMV here.) |
We went with gSOAP rather than Axis to avoid having a dependency on both a JRE and Axis just for building a C++ project. It's worked ok, which is good since the gSOAP code is horrible and makes it very daunting to fix any bugs in it.

No ... on all Windows platforms DWORD is 32 bits. LONGLONG or LONG64 is used for 64 bit types. |
It is defined as:

Therefore, DWORD is 32bit on a 32bit operating system. There is a separate define for a 64bit DWORD:
