I this correct?

Sir, I think I have not explained my problem briefly.here is the brief explanation of my problem I want to find the attributes of the removable drive so, I need to get the string of the drive I've done everything and stored the string value in the "store" variable I mean the variable consists the drive location(D:\) so that I can execute another system function called attrib to find its attributes. Thank you

Then it is simply a matter of creating the full command and parameter in a string and passing that string to the system command.
wchar_t sysCommand[128];
swprintf_s(sysCommand, L"attrib %s", store);
system(sysCommand);See also system, _wsystem[^].

I have no idea if this is the right answer to the OP's question, Richard, but the fact that you were able to ascertain something from it is impressive. :thumbsup:

Sir, errors are quiet similar to my initial work. i.e initially when I use system(store) it shows me an error the same error is showing when I use system(sysCommand); Error:
Severity Code Description Project File Line
Error C2664 'int system(const char *)': cannot convert argument 1 from 'wchar_t [128]' to 'const char *' CG C:\Users\User\Desktop\Analyser tools\Sub-Project\Sub-Project\USB informer.cpp 52Thank you for your kind help

Sorry, my mistake, you need to use
_wsystem. See the link I provided in a previous message. -
To sir DavidCrow: I am using Unicode characet set what should I do now? I am using only unicode and not multibyte Thank you for your kind help
You can't send a
wchar_tarray tosystem(). It's expecting acharpointer/array instead."One man's wage rise is another man's price increase." - Harold Wilson

Sir, I have completed everything and when I run my code the command window disappears immediately what should I do now? Thank you

The system process will only run the command that you send it, and then terminate. There are alternative ways of doing this: see the exec commands at Process and Environment Control[^].
Sir, I referred here Execute a Program with C++[^] and did this
ShellExecute(
NULL,
_T("open"),
_T("cmd.exe"),
_T("attrib"),
(show),
SW_SHOW);it is showing the show (I mean the directory) like this K:\ but not ececuting the attrib.how could I solve this? Thank you

If you are wanting to get the attributes of a file/folder, why do it the way we were doing it 30 years ago? See
GetFileAttributes()instead."One man's wage rise is another man's price increase." - Harold Wilson

Your parameters are not correct, and it will not work just by opening cmd.exe. You need to add the option to tell cmd to execute the sub-command in the parameter list automatically like:
PWSTR show = L"/k attrib D:\\";
ShellExecute(
NULL,
L"open",
L"cmd.exe",
show,
NULL,
SW_SHOW);Of course, the attrib command will not operate on a drive letter, and as David mentions, there are better ways of getting this information.

Sir, Is there any other way to execute some commands like this to a specific drive by giving the drive string at the run time? because I have to define the drive name here? I have referred to create process, shell execute etc., attributes is one of my functions I need to execute several different commands like this on a specific drive how could one do it? Thank you

Sir, my program will not do anything on its own. I have a added GetLogicalDriveStrings in a combobox which will show the list of drive present in the PC. Then if the user wishes to add a directory by pressing a push button, then cmd function should execute and create a directory or hiding folders and so on on the drive specified. I know it is much easier to do this manually but I am learning windows API so it will be helpful for my future use. Thank you
