i'd suggest you to turn to C++ solutions instead of sticking to C.

by the way :

char pszBuffer[NUMBER_LONG_ENOUGH];
 
::fscanf(myOpenedFile, "%s", pszBuffer);

I can't use this method, somehow the character save in the file turns out to be in funny shapes and not the ones i input. Below is the code i used.

FILE *stream;
stream = fopen( "Result File.txt", "w+" );
char pszBuffer[500]; ::fscanf(stream, "%s", pszBuffer);

You can use ifstream for that purpose. You can extract formatted data from the stream by using the extraction operator ( >> ).

ifstream myFile("MyFile.txt);
int iValue;
myFile >> iValue;

See here[^] for more info.

EDIT: when looking at toxcct answer, I'm wondering: your file contains only pure text that you want to load into a string or does it contain numeric values that you want to load into an array (like an integer array) ?

i want get characters from the file and put it in one array. Can i use getline or other functions. This array must be able to save the file content exactly because i want to use the array to save it in another file at a specified location or path.

Try using CString.

what are you trying to do with all these lines of code ?

the OP only wants to read his file in a buffer !
