You need to identify the dependencies between data elements in the interactive side and elements in the constraint side. Then when a constraint element is changed, you only update the interactive-side data which is dependent on it. This structure has been studied in Artificial Intelligence for some time. The main references are: Doyle, J., "A Truth Maintenance System," Artificial Intelligence 12 (1979) 231-272. de Kleer, J., "An Assumption-Based TMS," Artificial Intelligence 28 (1986), 127-162.

Thanks for the tip. I cannot use caching because every SOAP call is different, even if all the input arguments are the same (it's a kind of complex reservation system using mathematical formulas). I like the trick using the sequence number, but I would keep this as a last alternative. I was just hoping there would be a method to get from the .Net framework that the client has left (because of a time-out) before actually returning the result, but apparently, this isn't the case. Thanks for the tip anyway. Patje Enjoy life, this is not a rehearsal !!!

Simple Trick - Install video card with more Video RAM. Avoid using DDB, use DIB bitmaps isntead (they can reside in regular memory). 'Share' handles to objects - instead of duplicating a 1-pixel wide black pen 200 times, etc. No shirt, no shoes, no brains, no service.

My first thought is to encapsulate the ASCII and UNICODE streams with in your own class (or template) then duplicate the methods. It may be as simple defining operators for both char and wchar_t (I dought it thou). class transparentstream { std::ofstream asciiFile; std::wofstream unicodeFile; ... }; INTP "The more help VB provides VB programmers, the more miserable your life as a C++ programmer becomes."

Thanks Ryan, I looked at gSoap but because of its GPL license we cannot use it in commercial software. Although a commercial license for gSoap exists, I further looked into the .NET classes and since they are free (but tied to the Windows platform which isn't a problem for us) .NET looks the way to go. So far I made a successful small .NET .exe SOAP server, and I'm looking further into embedding SOAP logic in our server applications that way. Thanks anyway for your information.

Thank you both for your input. I think I'll have lot to read the next days. Enjoy life, this is not a rehearsal !!!

you could try to overwrite it... i coded a c++ framework for kernel mode(i didn't have to overwrite the new/delete operator, cause there is none) and it works fine, also with different compiler versions. Don't try it, just do it! ;-)

My guess is that the profiler isn't telling the truth. The fact that it isn't showing EnterCriticalSection rings alarm bells. Run the program in the debugger and verify that EnterCriticalSection is indeed being called. It must be. If there is a bottleneck it will be at EnterCriticalSection when another thread has it locked. LeaveCriticalSection should be instantaneous. Neville Franks, Author of ED for Windows. Free Trial at www.getsoft.com

You have probably done this but MSDN suggests that instead of /PDB:NONE you use /Zi. From the description it sounds like they do the same thing.:confused: // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie

Thank you Joaquin, I finally found some time to experiment with this. I started from the Microsoft article you referenced but that did not work because there seems to be something like an old STL and a new STL. The article only worked for the old STL, and not for the new one. But after some digging into the documentation, I finally found the solution. Thanks for your help. Maybe I write an article on this.

I would inherit from ostringstream, overloading output stream operators for your formatting classes. If the format written is binary (contains null characters) it needs special handling. (Remember that std::endl doesn't just append a newline character. It also makes the stream call flush(). Hence, you need to consider how the flush() method should behave when using this class.)

Thanks, that would seem acceptable for applications that only need to load a few records from the database. In our situation, lots of records are loaded; in some situations, the whole database is loaded. We're speaking of about 100,000 records, sometimes even millions of records. Preventing updates while loading the database, or even worse, preventing applications from starting up as long as someone is saving is not acceptable in our situation. Do you know if the next version of SQL Server (is this SQL Server 2003?) will have the concept of read-only transactions? Thanks. Enjoy life, this is not a rehearsal !!!

My company has several products that we use to implement Computer Telephony Integration products in call centers. Some of the products only make sense in a call center environment. However, a couple of them could easily be used in just about any environment. One of those products is Dialect Data Repository. Basically it is an in memory database or scratch pad. The information on the website is probably not the technical information you are looking for, but it should give you some information. Take a look at http://www.ctilab.com/01ADialectProd.asp#RDR
