Yes sir store is now carrying the value D:\ I want to execute it by using the variable. What should I do now?
|
|
|
|

That still makes no sense, you cannot execute D:\.

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.

Thanks, it was somewhat easier than many of the questions we are seeing.

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 52
Thank you for your kind help

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_t array to system(). It's expecting a char pointer/array instead.

Sorry, my mistake, you need to use _wsystem. See the link I provided in a previous message.

Sir, It works now Thank you for you kind,quick and constant help!

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.

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

Then start using it. Trying to do all of this via system() and ShellExecute() is all but completely wrong.

Thank you sir I made it for now using ShellExecute function but I will try to do with the function (GetAttributes) suggested by you
|
|
|
|
|
I showed you how to do it in my correction of your code.
