Hi all,
I'm going out of my mind on this problem and would really appreciate some help. I am currently writing an NT service that has two threads running. One thread is at a point where it has to create a network message and send it over a socket. However, when I try to malloc some memory for a buffer I get an NT_STATUS_ACCESS_VIOLATION exception. The code looks simple enough to me:
totlen = sizeof(BH_MESSAGE) + msglen;
char* totbuf = (char *) malloc(totlen);
Any ideas coz I'm really going  crazy
Regards,
Mark

Probably the heap got corrupted before your malloc call. A buffer overrun is the most common cause, and it's usually a hard thing to find; there are several tools on the market to help debug heap corruption.
A simple (and cheap) thing to try is calling _CrtSetDbgFlag with at least the _CRTDBG_CHECK_ALWAYS_DF flag set.

You can make an app that is win32 that emulates a console in a rich edit view.

can u explain more about this... cause i cannot get what u mean?

I am trying to make it easy for you. Menuing is already implemented in Win32, you might as well use the existing system. Otherwise you must go waaaaaaaaay back in time and dig up some library like turboC to implement this.

Damn, I think I'm all confused now ... why on earth would you need to use openGL to create a menu for a console application ?!

Yes I am having trouble understanding the question - let alone answering it.

Do not use OpenGL - that is a graphics library, and has very limited event (read mouse click) support. Are you being asked to write your own custom menuing system for a console application? If so - it simply a matter of doing some hard work over the next few days.

The data structure would something like
vector < map < string, void* > >
where the void* points to each of your functions, and the string is what is displayed in the menu.

Are you saying that asking questions to get a better understanding of the problem is prohibited?

well, if it's for an openGL application ( not the same thing as a console application ) , have a look at GLUT, the OpenGL Utilities Toolkit (http://www.opengl.org/documentation/spec.html[^] )
If you want to do everything manually, it's a lot of work, you need to draw everything, handle the different messages ( mouse movements, callbacks, ... ).

I'm trying to use the Boost Regex[^] library in my MFC SDI app but am having some problems including the files as they instruct.
I've built the library per their instructions[^]
I added the C:\boost path to my include directories for my project
I added #include <boost/regex.hpp> to the top of the file I intend to use it in ... yet I still get a compile-time error saying the following:
MyAppName fatal error LNK1104: cannot open file 'boost_regex_vc7_mdid.lib'
Any ideas what I'm doing wrong, or how to fix it?
Thanks very much,
Dave

You also need to add the boost library path in the options of your vc++ installation

I tried adding the C:\boost path to the VS.NET library includes path, and it diesn't work.
I also tried adding C:\Visual Studio .NET\Vc7\lib (where that library file actually resides) to both the VS.NET library path definition, and the project library definitions path and no luck.
One more thing ... I'm not using pre-compiled headers ... if that would make any difference.
Thanks for the suggestion. Any others?

I ended up including the path to the .lib files in the linker section of the properties.
I'd forgotten to do that, and the setup instructions were somewhat vague.

Hi all,
I'm using a list"double" variable in my code. Even though I added the #include "list" to the beginning of the file, I keep getting a 'undeclared identifier' message. What's missing? Best,
Ralf.

Sure you can. Just click on the < and > in the Formatting bar above the smileys.

Be sure to use:
using namespace std;
or use:
std::list<double>
