HI to every body.
I would like to know how can I use data stored as RT_RCDATA in the resource section, I found this code some where in this forum but no explanation on how to use it, can some body please give me an advise on how to read the data stored. Question

section '.rsrc' resource data readable
directory RT_RCDATA, files

resource files,\
01, LANG_NEUTRAL, MyText,\
02, LANG_NEUTRAL, MiscData

fileres MyText, 'MyText.txt'
fileres MiscData, 'sea and beach.jpg'

Hi alonso,
You need to locate and load your resources using:

Code:

invoke FindResource,[hInstance],01,RT_RCDATA
invoke LoadResource,[hInstance],eax
mov [hData01],eax

Your data will be in global memory pointed by hData01.

Alonso,

You can use also the FILE directive to include text and misc. data in your program.

Pelaillo I tried your code and it worked just fine but it does NOT need the FindResource function since the name you type after fileres contains the handle to the specified resourceâ€™s info block (the same returned by FindResource function).

invoke LoadResource, NULL,[MyText]
invoke LockResource, eax
mov [hGlobal],eax ; Pointer to where the data starts
invoke SizeofResource, NULL,[MyText]
mov [dwFileSize], eax ; EAX contains the file size in bytes

section '.rsrc' resource data readable
directory RT_RCDATA, files

resource files,\
01, LANG_NEUTRAL, MyText,\
02, LANG_NEUTRAL, MiscData

fileres MyText, 'MyText.txt'
fileres MiscData, 'mar y isla.jpg'

THANKS TO EVERY BODY!! Smile
