I want to list all the installed programs like control panel Add/Remove programs. I know all the items would be list in the registry path:
'HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall'.
But, the problem is, there would be too many items if I enumerate the key, all system update packages and other small applets included,too. I only need basic information of the installed programs like control panel do, how to do that?
Thanks

Please check this article, it will be useful

This article to doing the same, only you can filter those which you dont want.

Thanks for your reply.
But it still list all the programs installed on the system, updates, addons included.

What you want is just not possible. Windows does not know about all programs that you have installed (especially the older ones), only the ones that have gone the "standard" route and updated the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall key.

maybe it's a complicated work.

The Official method (used by "Add/Remove program") is with COM interfaces)
See on Win32 ng[^]
where the code has often ben posted (C++)

Thanks, I'll have a try

Don't bother. A quick look through kilt's post history shows that his suggestions are all but completely useless.

My Windows MFC Application will receive a structure from a Unix machine (Big Endian) over UDP.
The structure has the following data types:-
struct RXData {
double timeStamp;
double item1;
long item2;
double item3;
int flag1;
bool state;
};
What do I need to do on the Windows platform to get the data in the correct format; i.e. do I use procedures like theses below - I did try but still not getting the correct answer.
float swap(float d)
{
float a;
unsigned char *dst = (unsigned char *)&a;
insigned char *src = (unsigned char *)&d;
dst[0] = src[3];
dst[1] = src[2];
dst[2] = src[1];
dst[3] = src[0];
return a;
}
short convert_short(short in)
{
short out;
char *p_in = (char *) ∈
char *p_out = (char *) &out;
p_out[0] = p_in[1];
p_out[1] = p_in[0];
return out;
}
The floats give incorrect values.
Any suggestions for this simple scheme please.
Regards,
Andy.

Actually you need to convert doubles, not floats (i.e. 8-byte values instead of 4-byte ones).

you said the struct holds doubles, yet you show a swap function dealing with floats, not doubles?
apart from that, everything looks OK. Although there are other schemes, some involving a union.

I cannot find a 'useful usage' of a union to reverse byte order (while I highly appreciate unions as 'variants').

I am writing in C and using using VC++ 2008, .net 3.5 sp1 framework using a USB - to serial converter for serial port -- it comes up as COM4 on Windows 7 x64 as the operating system.
Need to read and write to a circuit board which gives out continuous output on the serial port.
I also do not know the header files to include in my main program to get the code to work.
Thanks,

Output is a very generic terminology to use when asking for serial port advice.
What are your requirements?
Are you sending data over serial or do you require granular control over individual data pins?
For transferring data over serial this MSDN article contains nearly everything you need to know:
Serial Communications in Win32[^]
If you need granular control over data pins this BeyondLogic article gives in-depth details:
Interfacing the Serial / RS232 Port[^]

I hope client can send some secure data at connect time vs CSocket::Connect, so that server can read the data and knows it is my client connection, or server rejects the connection immediately.
Is it possible to send user data vs CSocket::Connect?

Don't think so - I think authentication (for that's what you want) has to be done separately post-connect.

In order to send and receive data during a connect operation you will need to use WSAConnect() rather than CSocket::Connect(). Keep in mind this is protocol dependent and is not supported by the TCP/IP stack.

Note Connect data is supported only on ATM (RAWWAN) over a raw socket. TCP/IP in Windows does not support connect data.

from the msdn about WSAConnect:
The lpCallerData parameter contains a pointer to any user data that is to be sent along with the connection request (called connect data). This is additional data, not in the normal network data stream, that is sent with network requests to establish a connection. This option is used by legacy protocols such as DECNet, OSI TP4, and others.
Note Connect data is not supported by the TCP/IP protocol in Windows. Connect data is supported only on ATM (RAWWAN) over a raw socket.

Hello,
You cannot do such a thing. Any validation should be done after accepting the connection only.

No, a TCP stream must connect before exchanging data.

My client/server program is almost completed, the server may accept thousands of clients in real use.
As test, I generated 20 clients with heavy conversations to server, all are fine.
But ..., I never use any thread for listing, receving and sending.
From CSocket idea, I do think thread is not neccessary, however, I have a little suspection about this.
If you have created real commercial client/server programs before, which used CSocket, I need your comments:
Do you think thread is a must (or good, better) for client/server (TCP/IP) CSocket program? if yes, why?
Thanks
