I wish to display a help file (*.chm) in a VC++ 6.0 MFC Application .
I've created the CHM file using a software and I just want to display the chm file when the Help button is clicked.
It's better if u can give a sample code.
Your help is highly appreciated.
Thanks in Advance

When a release build dies with "the instruction at location xyz..." how do I find out the where in the source that was? If I choose to see the stack dump, can that tell me (assuming no stack corruption) what my calling path is?
I assume you need some kind of separate debug info file (with address to function lookups or something) generated at build time.. but I'm not sure what debug info I need to generate, and then how I would tie up the stack and instrucion addresses to functions?
Thnx in advance.

you need a "Map" file. it'll give you the addresses of all the funcitons in your EXE.
there's a checkbox, somewhere in the linker options, to turn this on.

Does VC6 support the __FUNCTION__ macro? If so, where is it defined? If it doesn't exist, can anybody recomend a similar method of getting the function name?
|
|
|
|
|
Wouldn't "__LINE__ of __FILE__" suffice?

Normally yes, but in this instance I really need to get a hold of the function name.
|

No, that was added in VC7 (or maybe 7.1, I forget). There's no simple way to do it in 6.

Why, are you wanting a VC++ answer?

it might help me too, a guy in the C# forum replied and said I might find the answer in c++

|

If you have a question C++ you can ask on this forum not shift to another forum

Your response would be valid had he asked here first and then asked in a separate forum. In reality, he first asked in the C# forum and was then redirected here.

hi
how to validate a given directory path ( in a remote machine whether the path is valid or not) in vc++?
and also how to execute a dos command in MFC?

How about PathIsDirectory()?

Like you would anything else, use CreateProcess() or ShellExecute(). However, some DOS commands have an equivalent API (e.g., dir, copy).

Hi
This is only working for local directories. Not for remote shared path validation. how to check the remote machine shared directory path is valid or not?
|
|
|
|
|
Is PathIsUNC() any better?

Hi there everyone!
I've been coding a multithreaded application for a while and due to some big changes in the application I've decided to recode it all from the start.
Together with the new changes, thread safety has really become an issue and it's made me realise how hard it really is to design a multithreaded application. So after thinking for weeks and reading all I've come over I think it's time to ask around for some advice :]
My application runs two main threads:
* One for the GUI (Win32 Console)
* One for a TCP socket listening for incoming HTTP requests (yes, it works as a basic webserver)
The application also runs 10 worker threads for handling http requests. These threads are in a pool that keeps handling each and every http requests that is queued.
The reason I use a thread pool is that handling a request can take some time, for instance if a complicated script is executed or a large file is requested and I don't want one request to block another.
The Webserver supports a very simple script langauge (similar to ASP). Using this, the client can both access and modify a lot of objects on the server, such as Users, Statistics, Settings.
This is where the problem lies: These objects needs to be thread safe. Say for example that one http request modifies a username while three another http requests at the same time wants to output the username.. adding to this, maybe the GUI also wants to display this username at the exact same time... this is where it can all go very wrong if it's not thread safe.
As a note I can say that I'm currently using the boost library 'shared_ptr' for accessing these objects through manager classes, for example: UserManager, LogManager, StatisticsManager.. etc Maybe one possibility would be to write a wrapper around the shared_ptr for thread safety??..
But to be honest I really haven't come up with the perfect way to solve this. It's a lot of objects that can be accessed by both the GUI, the Webserver and the Worker Threads, so honestly, wrapping every get/set accessor up in Mutexes isn't a very pretty solution.
So well, I thought it might be a good idea to see if anyone here have any ideas on how I can design this, or just do some brainstorming :]
thanks!

Presumably the manager classes are created before the worker threads are active, so putting synchronization at that level seems appropriate. It is necessary then to prevent one thread from writing changes to these objects while others are also trying to read or write to them.
This article presents one technique for accomplishing such synchronization:
