Custom Resource getting extra data?
Hi everyone,
I have a custom resource in a program that I need to recieve during runtime. During runtime, it retrieves the text, but there always seems to be one or two extra characters on the end.
This is the function:
char * get_code() {
HRSRC res_handle = FindResource(NULL, "MAIN_CODE_PHP", "PHP_DATA");
DWORD size = SizeofResource(NULL, res_handle);
char * code =(char*) malloc(size);
code = (char*) LockResource(LoadResource(NULL, res_handle));
printf(code);
return code;
}
The resource contains the following text
echo "SOME CODE! BLAH BLAH";
But when i use printf it prints
echo "SOME CODE! BLAH BLAH";(
I am confused? Why is the program grabbing the extra character?

My guess would be that the resource doesn't have a NULL character at the end, so printf is printing everything until it finds a NULL character.
BTW, why do you malloc the buffer, then never use it? Perhaps you need something like:
char * get_code() {
HRSRC res_handle = FindResource(NULL, "MAIN_CODE_PHP", "PHP_DATA");
DWORD size = SizeofResource(NULL, res_handle);
char * code =(char*) malloc(size+1);
memset(code, 0, size+1);
const char *res= (const char*) LockResource(LoadResource(NULL, res_handle));
memcpy(code, res, size);
printf(code);
return code;
}

Actually I take that back, when Try to compile the file i get
"sytax error missing ';' before 'const'"
and
" 'res' undeclared identifier"
When I comment out the memset line it compiles, but it again grabs the extra characters.

no thats what throws me off, the semi colon is thereWell, could you post your code then?
'const' is a keyword; if your compiler can't parse it right - most likely the previous line is screwed up.
# 7 Re: Custom Resource getting extra data?
fixed it, the problem was that since memset returns a value, the compiler was getting angry that I was not assigning that value to a variable.
It was easily fixed by this line:
char * dummy = memset(code, NULL, size+1);
