Thread: directory path coding

hi all,

i need to set a directory path into a Cstring variable, as follows:
CString directory;
directory ="\\D:\data\data";

but error code occur said that d: is unrecognised character escape sequence, how do i cope with that?

thanks!

Code:

directory ="\\D:\\data\\data";

Code:

i use these coding:

   dest=  "\\D:\\data\\data\\file14.txt";
   HANDLE hFile = CreateFile (dest, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_ALWAYS, 0,NULL);

   if (hFile == INVALID_HANDLE_VALUE){// if setting/file not valid
		DWORD dw = GetLastError ();
		debug = "Step 1";
		detail.DetailValue = debug;
	}

detail.DoModal();

the above command display "step 1"

i still can't access the file, do u know why? thanks very much!!

now i use this:

Code:

HANDLE hFile = CreateFile(L"D:\\file.txt", GENERIC_READ, 
                   FILE_SHARE_READ,
                   NULL,
                   OPEN_ALWAYS,
                   FILE_ATTRIBUTE_NORMAL,
                   NULL);

	CString debug;

	if (INVALID_HANDLE_VALUE == hFile){// if setting/file not valid
		
		debug = "Step 12";
		detail.DetailValue = debug;
	}
detail.DoModal();

i still can't access the file, it displays the step 12, anyone know why? thanks a lot!!

Any reason you're using CreateFile instead of std::istream?

coz i need to display the content in the dialog editbox

can istream do this?

Yes, and it's much simpler too. Not to mention pretty much the C++ standard.

but how to display the getlasterror code?
by the way i use the TEXT() function but no difference

coz ("D:\\") or ("\D:\\")makes no different in result and ("\D:\\") will get warnning

i have got the eror message from the getlasterror:

the data area passed to a system call is too small

but i dun understand, how can i fix it? thaknks!!
