Re: Compiling a Data File as as a Resource

Maybe my problem is that I'm trying to build a .lib file, not an .exe file.
In the next 2 lines:

    HINSTANCE hInstance = AfxGetResourceHandle();
    HRSRC hRsrc = FindResource(hInstance, _T("IDU_FILE1"), _T("TEXT"));

hInstance is non-NULL but hRsrc is NULL. "IDU_FILE1" is a "TEXT" file that
is in my .rc file and the file itself is in my source directory.

FYI, I've tried setting hInstance to NULL (since the resource is in the same
project) but that doesn't work either.

The purpose of my effort is to have a very large data file (now over 2000
lines with about 50 pieces of data in each line - string, float, int, BOOL,
etc.) who's data I want to be accessible to many different dialog boxes in my
applications (about 20) hence my attempt at making it a library file which I
can include directly into my apps and not give it out. Also, after I open
it, I need to read it line-by-line with _stscanf_s() so if you have any
suggestions, they would also be greatly appreciated.

sorry, didn't read that you were working with a very large char resource...
you probably don't want to allocate a buffer then copy over the buffer, then
delete it... probably want to lock the resource, then read it in.

HINSTANCE hInst = <whatever app instance handle is> or
<AfxGetResourceHandle() if mfc>
HRSRC hRsrc = FindResource(hInst,MAKEINTRESOURCE(nIdResource),"whatever your
resource type is");
HGLOBAL hGlob = LoadResource(hInst,hRsrc);
int nDataLen = (int)SizeofResource(hInst,hRsrc);
char* szData = (char*)LockResource(hGlob);

// now do your work on szData (which is nDataLen long)

quick example of how to read it in from your app resource section via



HINSTANCE hInst = <whatever app instance handle is> or
<AfxGetResourceHandle() if mfc>

 HRSRC hRsrc = FindResource(hInst,MAKEINTRESOURCE(nIdResource),"whatever
your resource type is");
 HGLOBAL hGlob = LoadResource(hInst,hRsrc);
 int nSizeGlob = (int)SizeofResource(hInst,hRsrc);
 char* tmp = new char[nSizeGlob+1];
 LPVOID lp = LockResource(hGlob);

// do your work here with tmp

delete tmp;

I have a very large file of data that I use for one of my applications.
It's format is currently space delimited but it can be an Excel file, a


file or just a text file. The lines are long and contain about 50



information (strings, integers, doubles and bools). There are over 2000

Right now I have to distribute this file with my application because I'm
reading and using the data from it and I've had people modify the file
(accidently or
on purpose) and then my application doesn't work properly. Is there a


that I can make the data part of my EXE application? I know there are
"data" commands in Fortran and Basic - is there anything like that?

It would be even better if I could just compile it right into my


somehow. Can I include it as a Resource and "read" it somehow (like
formatted input)?

Right now, I just _tfopen_s() the file and:

while(bSearch && (
  _ftscanf_s(ifptr, _T("%s %s %s %s %f %f %....."), ............)!=



-- do what I need --
} /* while */
