This is going to sound snarky...
If you don't realise just how hard a problem this is, you're not qualified to do it.
What do you mean by installed? You can look at Add/Remove programs, and see how many things are there, how many are missing, and how slow it is.
For hardware? Well, drivers can be installed, but maybe they handle different devices? What about things on your serial port(s) ?
How about hardware drivers that may not even represent a physical device?
I can think of a few more gotchas, but that should be enough to frighten you.
If I could answer your question in a more full and helpful manner, I'd be a lot wealthier, and working from Seattle. (Or not.. maybe a penthouse in New York...)
Iain.

But only for those programs that were installed in a "standard" way. Windows has no way of knowing about all programs that have been installed.

one dimensional array of char. The pointer would contain the base address.

two dimensional array of chars or better said, one dimensional array of strings in some scenarios
Some things seem HARD to do, until we know how to do them.

in C++ ? the same as in C.
char* is a pointer that points to a char.
char** is a pointer that points to a char*.
when char pointers are used like strings (C style strings then), char* is a string, and char** is an array of strings...
but the later assertion depends of the context...

For catching F1, you've to handle WM_HELPINFO message. Check here[^] for code snippet.

Hello all,(Sory about my English) Please help....
VC++ 2005.
I have a func that call to Socket,Bind, Listen & Receive.
I call this func from timer that see if the Client send data.
I get the data in the first call but in the second call I got errors.
I understand that I need to operate the Socket,Bind, Listen only once.
I got err when put this line in a global scope or as a member data in class declaration:
Socket^ listenerSocket = nullptr;
So, I tried to store it with the help of global pointer.
It is good till I call the funcs of the Socket type, after all it just pointer that set to some place in the memory.
Socket^ *GlistenerSocket = nullptr;
Socket^ *GserverSocket = nullptr;
int CMotoScopeDlg::DoSocketGet( String^ server )
{
Socket^ listenerSocket = nullptr;
listenerSocket = gcnew Socket( AddressFamily::InterNetwork,SocketType::Stream,ProtocolType::Tcp );
if (false == SocketBindFlag )
{
listenerSocket = gcnew Socket( AddressFamily::InterNetwork,SocketType::Stream,ProtocolType::Tcp );
GlistenerSocket = &listenerSocket ;
(*GlistenerSocket)->Bind(hostEndPoint ); //Only once
(*GlistenerSocket)->Listen( 4 );
SocketBindFlag = true;
}else{
listenerSocket = *GlistenerSocket; //check this. allocate place??
}
Socket^ serverSocket = (*GlistenerSocket)->Accept(); //ERROR at second time
If I could put this Socket variable in the global place it will help.
Thanks in advance,
Eyal

As you have Socket^, and are asking syntax questions, you are in the wrong forum.
You'll get more help in the Managed C++/CLI forum.
You'll get even more help if you read the rest of the posting guidelines and use pre tags.
Good luck,
Iain.

Hi,
I am using WM_COPYDATA message to send a string from one application to other but how can I do that, my code is here:
TCHAR *szPath=new TCHAR[g_szSelectedFilePath.GetLength()+1]();
memcpy(szPath,g_szSelectedFilePath,g_szSelectedFilePath.GetLength()*2);
delete[]szPath;
COPYDATASTRUCT cs;
cs.dwData=32;
cs.cbData=g_szSelectedFilePath.GetLength()*2;
cs.lpData=szPath;
::SendMessage(hWindow,WM_COPYDATA,NULL,(LPARAM)(LPVOID)(&cs));
what is the use of "cs.dwData=32" I could not find?
When I recive this message in other application only first 2 char are visible of the string and others are garbage chars.

You should really read this[^].

"High speed never compensates for wrong direction!" - unknown

As i see this, after you copied some string into your szPath you allocated you delete it and then pass the pointer which now points at the deleted memory area to the copydata.
The dwData member -as far as i know- is just a value you can pass over to the receiver, it can be anything that fits your needs.
