While trying to build this project I get the following link error:-
<code>Error 26 error LNK2019: unresolved external symbol "char * __stdcall _com_util::ConvertBSTRToString(wchar_t *)" (?ConvertBSTRToString@_com_util@@YGPADPA_W@Z) referenced in function "public: virtual long __stdcall SmartGraph::SetLegendText(wchar_t *,long,long,long,long)" (?SetLegendText@SmartGraph@@UAGJPA_WJJJJ@Z) SmartGraph.obj</code>
It seems to be caused by the line:-
<code>m_strLegend = _com_util::ConvertBSTRToString(strText);</code>
I am using VS 2005, any suggestions please.

You need to add the library comsupp.lib (see [^]) to your project Linker command line options.

Welcome. Having been here six months I can highly recommend it as a place to learn a lot and help other a bit as well.
By the way please post chatty messages in the Lounge to avoid being flamed and programming questions anywhere but the Lounge to avoid being thoroughly barbecued
Nothing is exactly what it seems but everything with seems can be unpicked.

You can't remove elements in such an array. And even worse, your array will be initialized with garbage structures (except if you provide a default constructor to your structure).
I suggest you take a look at a std::list, this will do what you are looking for (but you'll probably need some time to learn how to use it, look for some tutorials).
|

|

You cannot remove an element from a "hard-coded" array like that, you will need to either mark/tag the element as "removed" or copy the elements that you want to keep to a new array and remove the old one. but that sucks.
If you need to add and remove elements to an "array", I suggest you have a look at ode>std::list (not std::vector).
|

Since the array is allocated onto the stack you cannot delete (i.e. remove) items. However you can erase the info wherein, for instance:
...
for (int i=0;i<100;i++)
{
if (member[i].number == search)
{
member[i].number = -1;
memset( member[i].name, 0, 50);
memset( member[i].address, 0, 30);
break;
}
}
...
You can also use an old (soft removing) trick: swap the found item content with the (currently) last one and decrease the element count.
BTW: don't use explicitely numbers (eg. 50, ...) in code, use meaningful symbolic consts instead (e.g. NAME_SIZE, ...).

think STL buddy, think STL !

Otherwise I'll keep getting tons of 1.0!!!!
Honestly, I rarely suggest STL usage to newbies.
STL is very good (in fact, state of the art if I have to compare it with, say MFC counterparts) but IMHO a lot of people find too hard the STL learning step and I'm afraid to suggest a rather advanced topic to a newbie (even if the benefits are worthy the effort).
[added]
Furthermore, I think a C++ programmer must be able to do some memory management before switching to container classes. If one just don't like the argument there's a pletora of managed languages...
BTW Who cares about stupid 1.0 of stupid guys ?

is it better like that ?
lol
actually, i prefer confuse even newbies a bit with STL, rather than push then in dynalically allocating memory, then leading toward memory leaks...
pushing people into STL will make then make the effort of learning it... since then, they will never look around anymore 
so, please, edit your post and slide a little STL note in it

If they shouldn't face memory allocation then is better a C# migration. On the other hand, if they want the metal then metal to them!

STL has the grat advantage of being rigorous. It turns out to be a (learning) disvantage for not-so-rigorous people  .

You know I'll never do that.
BTW: who has changed the 1.0 vote(in fact was a 2.0) to my post (i.e. only the original poster has the power to?)

ok, you got me... was me 
but hey, at least, the voting system has that better than the previous one, that if we want to change a vote, we still can...

Can anyone tell which dlls(VC++) need to be added to simple ftp application in order to have transport layer security.
|
|
|
|
|
That would depend on the implementation of FTP that you're using. WinInet does not support FTP over TLS. You'll probably need to obtain a third-party FTP library or implement it yourself. The use of TLS to secure an FTP connection can be found in RFC 4217[^].
To use TLS, consider using Windows' built-in implementation. See Creating a Secure Connection with Schannel[^] for details.

I have a problem executing a particular child process from my Windows MFC application. The call is simply the name of the executable and an input file as commandline option (see below):
CString commandline = "runall.exe datafile.txt";
switch(WinExec(commandline ,SW_SHOWNORMAL))
{
error handling.....
}
The child process starts, but terminates almost immediately without doing its simulations, and without returning any error values. In a console-window the process runs correctly when using the same call. This puzzles me since I also run several other child processes from my application, whithout experiencing the same problems. Launching the process through functions, like spawn or system, etc., does not help either. This child application uses quite a deal of memory, so it could be a memory problem? However, since it runs correctly in a console window even when the parent application is also running, the total amount of memory on the computer must be large enough. Are there some settings I could alter to increase the memory that can be allocated by my application? Any hint on what might be the problem here will be highly appreciated!
Thank you in advance!

My first guess would be a relative vs. absolute path issue.

No, I have checked this. The call work fine if I use it for another child application.
Thanks anyway!

But in your code snippet, commandline is using a relative path. Change it to an absolute path to see what happens.

Well, using
commandline = "C:\\mydir\\runall.exe C:\\mydir\\datafile.txt";
does not help.
