File Reading and storing to 1 variable

ok i think i got further this time

Code:

		fseek(fal, 0, SEEK_END);
		pos = ftell(fal);
		fseek(fal, 0, SEEK_SET);
		fread(&ReadTxt , pos , 1 , fal);
		_stprintf(testt , _T("%d") , pos);
		SendMessage(hwndList , WM_SETTEXT , (WPARAM)sizeof(ReadTxt) , (WPARAM)ReadTxt);
		MessageBox(0 , testt , _T("test") , 0);

the messagebox is showing the correct size but its setting the text as all wide chars

> SendMessage(hwndList , WM_SETTEXT , (WPARAM)sizeof(ReadTxt) , (WPARAM)ReadTxt);
SendMessage(hwndList , WM_SETTEXT , (WPARAM)pos , (WPARAM)ReadTxt);

still not working

also i had 2 WPARAM's i changed it to

Code:

SendMessage(hwndList , WM_SETTEXT , (WPARAM)pos , (LPARAM)ReadTxt);

and still no luck

try this:
*((char *) (rand()) = 0;

then run it until it works

e: oh well

char stuff[124124];
int pos;
FILE * file = open me a file;

fread(stuff, 124124, 1, file);
fseek(file, 0, seek_end);
pos = ftell(file);
stuff[pos] = 0;

printf(stuff);

i dont think that will help.

this program works fine in C but soon as its with unicode it goes nuts

Code:

                int pos;
		TCHAR SaveTxt[2048];
		TCHAR ReadTxt[128];
		TCHAR testt[128];
		FILE *fal;

		fal = fopen("users.txt" , "rw");

		if(fal == NULL){
			MessageBox(0 , _T("list not found") , _T("Error") , 0);
		}

		fseek(fal, 0, SEEK_END);
		pos = ftell(fal);
		fseek(fal, 0, SEEK_SET);
		fread(&ReadTxt , pos , 1 , fal);
		_stprintf(testt , _T("%d") , pos);
		SendMessage(hwndList , WM_SETTEXT , (WPARAM)pos , (LPARAM)ReadTxt);
		MessageBox(0 , testt , _T("test") , 0);

thats all of it.
its like its showing the buffer for ReadTxt because if i change the Arraysize on Readtxt say to 2 then it only shows 2 wierd widechar characters but if i keep it t hat big it shows a whole lot of it

fread(addresstoreadto, sizeofrecord, numberofrecords, file)

that is to say, stop using windows

fread(addresstoreadto, sizeofrecord, numberofrecords, file)

?
i have all of that right.

No. Don't program randomly, but learn to get and read information.

google "man fread" gives (1st answer) :

Code:

size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream);

ptr: The address of the destination block of data.
size: the size of an element of data
nmemb : the number of elements of data
stream: the stream object address.
return: the actual number of read elements

Say :

Code:

char a[123];
size_t read_nb = fread (a, 1, 123, fp);

1 : means one char
123 : means 123 / 1 elements

Could have been written:

Code:

char a[123];
size_t read_nb = fread (a, sizeof *a, sizeof a / sizeof *a, fp);

its like the buffer is becoming the variable data

Please don't copy and paste long strings of random data...

The value of a variable defined in a bloc is undefined.

Try this:

Code:

TCHAR ReadTxt[2048] = {0};

It makes things clear. (Filled up with 0's).

sorry about the long strings.

i think that helped abit becuase now instead of getting heap of 2048 chars i got 獤獦㈴㈲

but its still not working

im going to get some rest and will work on it when i get up ,
thanks every one for the help

ftell() does not return t_fpos, it returns a long.
