then, why don't you just gneerate your lib in a non MFC linked DLL ?
that way, your GUI (which is using MFC) will still use stdafx.h like it was, and in your lib sources, you can remove every reference to that file...
|

Actually, stdafx.h is not required anywhere, even in MFC apps.
The only required header files are the ones your code may need
to compile.
You are free to use or not use pre-compiled headers, and you can
name the associated pre-compiled header file anything you want to.
As mentioned, you need to turn off the use of precompiled headers
or you can change the name in the settings or the name of the file.
stdafx.h has been the default precompiled header file for so long
that many think it's required

HI all,
I have assembly generated code of an simple program
C++ code:
int main(int argc, char* argv[])
{
int i =10;
int j =20;
int k = i+j;
return 0;
}
some assembly code generated of out it is:
PUBLIC _main
; COMDAT _main
_TEXT SEGMENT
_i$ = -4
_j$ = -8
_k$ = -12
_main PROC NEAR ; COMDAT
; 8 : {
push ebp
mov ebp, esp
sub esp, 76 ; 0000004cH
push ebx
push esi
push edi
lea edi, DWORD PTR [ebp-76]
mov ecx, 19 ; 00000013H
mov eax, -858993460 ; ccccccccH
rep stosd
; 9 : int i =10;
mov DWORD PTR _i$[ebp], 10 ; 0000000aH
; 10 : int j =20;
mov DWORD PTR _j$[ebp], 20 ; 00000014H
; 11 : int k = i+j;
mov eax, DWORD PTR _i$[ebp]
add eax, DWORD PTR _j$[ebp]
mov DWORD PTR _k$[ebp], eax
; 12 :
; 13 : return 0;
xor eax, eax
; 14 : }
My question is:
What is DWORD PTR syntax is
in following line
lea edi, DWORD PTR [ebp-76]

Vikrams,
you've been asking here for long now.
when will you format your questions and make use of the <pre></pre> tags correctly ?
|
|
|
|
|
Thanks for the guideline.
|
|
|
|
|
dude, didn't I mention the <pre></pre> tags, and not the <code></code> one ?
BTW, thanks for the effort, but please edit once again...
thanks. it looks better now...

There are different machine code instructions for accessing memory
depending on what size the data pointed to is. DWORD means a double-word
(4 bytes), and a DWORD PTR indicates a pointer to a double word.

DWOD defines the bit size of the memory being used, PTR is a modifier indicating that we are pointing to a memory location.
The following are defined in x86
BYTE - 8 bits
WORD - 16 bits
DWORD - 32 bits ( double word )
QWORD - 64 bits ( quadruple word )
DQWORD - 128 bits ( double quadruple word )

If you already know the drive you can just access it as normal drive and search files using
1. FindFirstFile/FindNextFile
2. CFileFind
Can you explain more??

I assume you have read the article for which you have provided the link. Once you get the Drive for that USB it can be accessed as any other normal drive / folder.
To Get the file information read replies to following post.
Loop through directory[^]

yes you are right but i am stuck on geting drive name of USB.Plz plz help me to geting drive name of usb..
|

I just quickly read article provided by you and i found following line
Well, this is not bad, since at least you will know when an extra "disk" is mounted/unmounted, and you can get the affected drive letter by using the DEV_BROADCAST_VOLUME.dbcv_unitmask.

Sandip.

ok but i am not able to do that so if it is possible then plz help me through some example..
Plz help me

The device will need to be located using the SetupDiXXX() functions to enumerate all instances of the device's interface and get the device path to them. The path can then be passed to CreateFile(). With the handle that CreateFile() returns, ReadFile() can be used.
