The only thing I can see from your information is that HeapFree fails (what was the text of the message ???) when invoked by a number of library function that are in consequence to the OnSmtpTimer invocation, that -at certain point- assign and destroy a CMemFile that is no more there.
What does all that to happen, I don't know.
I don't see your code, your screen, your mind!
I can only suggest to investigate about what was OnSmtpTimer trying to assign and verify if (and where) something else destroyed it before. That's what debuggers are for.
Does "http://dofev.de" and "10022*Socket Error" means something to you?
Probably a CMemFile is attempted to be deleted after that point (look like after a socket connection failed). But ... it seems it is no more there. Probably it is something related a previous iteration of the message loop (so it is not on the stack anymore ...)

Hi
i got function name and argument type from UnDecorateSymbolName() method using vc++ MAP file. But i want how to argument names with using VC++ MAP file?
any idea please?

Have you looked in a .map file to see what it contains? If you had you'd have found the following things:
- They're simple text files
- They contain the addresses of things assigned by the linker and (usually) the size of those things
- They don't contain (unless I completely missed it a couple of weeks ago when I last had to look in one) names of function parameters.
Information about parameter names is not generally available to the linker as the compiler sorts out the mapping of argument names to position on the stack/register assignment, the linker doesn't have to know it.
I've no idea what you need this information for but remember C++ is a compiled language that, unlike Java, doesn't support any sort of type reflection or introspection. If you want to find out names of parameters your best bet is to look in something that's generated for a debugger - e.g. a .pdb file under VC++ and use something like the Debug Information Access API (which I've only glanced at, it might be rubbish, I can't comment).
Cheers,
Ash

I want to use wxWidgets to develop UI,and use it in MFC.
Thank you gurus.

My current project needs to be supported by IKnownFolder.
But I've never programmed with this kind of interfaces.
So anyone could help?
I'll really appreciate it if you could give some links or codes on what files should be introduced in and how and the initialization codes.
Thanks in advance.

Hi
I am using UnDecorateSymbolName() method get function name and argument data type. but i want actual argument variable name? i try this code like
void ExtractCppSymbol(char *szDecoratedName)
{
char szFunc[512];
if ( UnDecorateSymbolName(szDecoratedName, szFunc, 512, UNDNAME_COMPLETE > 0 ))
{
cout<

As far as I know the argument names aren't in the decorated name, so there is NO way to extract them.

i am using input mangled data from VC++ MAP file. This MAP file contains all details.
i parse MAP file and pass to UnDecorateSymbolName() method.
OR
how to pass input for argument name with mangle data?
|
|
|
|
|
The function and method names are decorated accordingly to the used calling convention, anyway what you can extract from a decorated name is, at most, the type of the formal parameters of a function (e.g. int, char *, struct MyStruct &, etc.), but not the name used in the source code.

Hi All
How can i check which OS is Install(xp,vista or Windows 7 etc) in System? Please help me
|

In addition to answer from Rejeesh, you can check out this[^] class. It does not support Windows 2008 Server and Windows 7 but the code could easily be updated in order to support these systems.

I am reading the TCP/IP Illustrated Volumn1 the Protocol. I find that is hard to acknowledge so many protocol. So I want to know which protocol are important for the network development.
Is the Volumn 2 needed to read?

You don't need to know every detail of the TCP/IP protocol stack for network development.

Good evening, CPallini
Do you think which protocols is important ?
|
|
|
|
|
It really depends on your needs. For instance, if you want to use sockets for developing a chat application then a general understanding of the TCP protocol would be required.

I agree with you. It's a lot of information, so how can someone decide which protocols are important?
Well, depends on who you are asking. If you are a beginner most in this book isn't needed, the author is a legend in his field, but I would rather start with practical experience to make yourself familiar with one thing at a time. There are very few cases where someone would need to know all low-level and high level-protocols in use like ARP, ICMP, IGMP, DNS, TFTP, BOOTP, TCP, TELNET, FTP, HTTP, SMTP and DHCP. I would pick one that you are interested in and then dig deeper. If you are already familiar with networking, let's say using TCP/UDP/DNS, it could be interesting to dig deeper and see how things work in detail and how on a deeper OSI-level. Let's say how IP/TCP/UDP/routing/switching/ARP works, definitely worth the time in the log run! But it could also that you want to specialise in application layer protocol design, then it would be better to focus on HTTP/IMAP/SMTP/POP/XMPP, the theory and design decision behind them. Another area to specialise is encryption, which algorithms have been used trough time, how to exchange keys/certificates and how communication integrates with applications.
Regarding Volume 2, not sure. The only book from W. Richard Stevens I personally own is UNIX Network Programming: Networking APIs: Sockets and XTI. Very detailed book, he really enjoyed writing about the topic and it's a classic if you are into network programming.
Hope it helps!

For 95% of programmers there are no important protocols. You'll just use a programming library to interface with the network. With TCP/IP you'll be using sockets (although older UNIX variants use another API known as TLI - I've not seen it in the wild in years though).
So for the programmer the API is the most important thing. Sometimes it's helpful to know the details of the protocols you're using (i.e. when something goes wrong and you're forced to use a packet sniffer or the like) but it's not a daily occurrence. The most useful protocols to know about are probably TCP and DNS as they're the things you're closest to when you're programming.

Transparent:It means there is no background pannel.The toolbar just looks like a floating imagelist(picture shaped button).
Enlarge:It means when the mouse hover on ,the hot icon would enlarge,bigger than the others,and would restore to it's original size when the mouse leave.
More:It would be much better if I can use png format pictures as resource.PS: Not use .Net Framework.(USE VC6 or VC2005)
Any suggestions would be fine!
Much thanks

I'd say, use Layered window(s)[^], handle mouse messages like WM_MOUSEMOVE[^], use GDI+ for loading PNG images from resource[^] or CxImage[^], possibly you could also need TrackMouseEvent[^] to know when the mouse leaves. I hope these pointers can help you start off in the right direction.
