FILE* problem
-
Hi, I'm now using the File* to save the data into text file. But i notice that if the file i want to save is in open mode, then the program will crash. Any way to prevent it? Below is snap of my code.. In *.h file
FILE *handle;
in *.cpp file
fopen_s(&handle,cPathName,"wt");
fprintf(handle,"<?xml version=\"1.0\"?>\n") // crash at here -

fopen_s(&handle,cPathName,"wt");
if (handle != NULL)
