I would like to store the data from the sensor after intializing or sending all the commands to the sensor i,e for continous data output??

Does this "sensor" have an API? How is it connected to the computer?

So just search CP articles for "serial."

You can also Google for the same.

How to record/process data sent from the sensor????

Having not coded very much serial stuff before, this is just a guess. Those other articles I referenced would have shown this, but I think you'll use something like:

HANDLE hPort = CreateFile("\\\\.\\COM1", ..., OPEN_EXISTING, ...);
ReadFile(hPort, ...);

Also see here.

lnewlength= recv(lnewSocket,(char*)lData,1024,0);

Can those be used with serial communications, or are they for sockets only?

Actually, if i would like to store the data of the "lData" parameter when lnewData[]={.....}(soem bytes) in storearray[], the how could i do? Is this correct??

if(lnewdata[8]==({..,..,..,..,..})

{
BYTE storearray[1024]= lData;
}
can i work so with a string???

What is lnewdata? Are you comparing or (supposed to be) assigning?

What is this? Try:

BYTE compare[8] = {0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08};
if (memcmp(lnewData, compare, 8 * sizeof(BYTE)) == 0)
{
    memcpy(storearray, lnewData, 8 * sizeof(BYTE));
}

Remove dependency of MSVCP80 and MSVCR80

Hello!

When I compile the release version of my application, it depends on MSVCP80.DLL and MSVCR80.DLL. Unfortunately this prevents the application from being run on a computer, where these runtimes aren't installed.

How can I remove these dependencies? Any way to statically link to MSVCP80.DLL and MSVCR80.DLL?

I assume there is some linker switch that does this and I've overlooked it?

Many thanks in advance and best regards
Dominik

Do you have the corresponding .lib files?

Go to the project settings.

It should open in Configuration Properties|General.

Next to "Use of MFC", make sure it says "Use MFC in a Static Library". (If not using MFC, don't worry, you still need to verify another place that applies even for all projects.)

Select C/C++.
Select "Code Generation".

Make sure "Runtime Library" doesn't have DLL in it' change if needed.

writing to stdin of console application

I need to run exe file from MFC app wich accepts data thru stdin.
How to pass that data to it and get its results from stdout. I've seen this link but it only handles reading results.

Of those applications that do it, most read from stdin and write to stdout? What exactly is it that you are trying to do?

I want to write numbers to stdin and read them from stdout after console is executed. This code on the link works with pipes, and I've implemented it for running a process and reading its output.
But when to write to stdinput pipe before or after createprocess() function?

when you write a very simple program you will need links some lib so that it can run.

so I want to know which lib will need on PC WINDOW platform .

main()
{
int i = 0;
}

the program need what lib to link?

even I create a plain/empty project with vc6(window console), it link many lib for me ,all is a must?

No, the only one that will be loaded at runtime is kernel32.dll.
