Let's start from the beginning... by looking at TASKMAN's startup code. Taskman is a very small win 3.1 program, but it's rich in surprises, as you'll see. After you disassembly
taskman.exe with WCB (see below) and *after* you have printed the listing, you may use the "Loader" utility to pop out inside winice at the beginning of Taskman:

start:
1FBF:4B9 33ED              XOR     BP,BP     ;begins
1FBF:4BB 55                PUSH    BP        ;save BP
1FBF:4BC 9A8D262701        CALL    KERNEL!INITTASK
...

  So we are set for snooping around "live", but first (and that's very important for Windows programs) we have to prepare a good disassembled listing of our target. You see, in DOS such a work does not make much sense, because the disassembled listing would not differ much from what you get on screen through softice, but in Windows, on the contrary, we can get quite a lot more out of all the information that is already present inside our target.
 
The following explains this point: You can use any good disassembler (like Winsourcer, from V communication, a good version, cracked by the ubiquitous Marquis de Soiree, is available on the web) but i'll use the disassembled listing of WCB (Windows CodeBack -> download version 1.5. from my "tools" page:
 
    http://ourworld.compuserve.com/homepages/FraVia/tools.htm).
 
WCB is a very good Win 3.1. disassembler, created by the ungarian codemaster Leslie Pusztai (pusztail@tigris.klte.hu), and, in my modest opinion, it's far better than sourcer. If you
use it, remember that it works from DOS: the main rule is to create first of all the *.EXL files for the necessary "mysterious" *.dll with the command wcb -x [mysterious.dll] and you'll be able, afterwards, to disassemble the *.exe that called them.
 
  But all this is not necessary for humble Taskman.exe, where we get following header information:

Filename:            TASKMAN.EXE
Type:                Segmented executable
Module description:  Windows Task Manager 3.1
Module name:         TASKMAN

and we can get straight the entry point code:

  1.04EB  FF363400                 push    word ptr [0034]

  1.04F8  FF363400                 push    word ptr [0034]

  1.0508  FF363A00                 push    word ptr [003A]
  1.050C  E89FFE                   call    WinMain
  1.050F  50                       push    ax
  1.0510  E890FF                   call    04A3

  This is similar to the standard startup code that you'll find in nearly *every* Windows program. It calls three functions: InitTask(), WaitEvent(), and InitApp().
 
 We know jolly well about InitTask(), but let's imagine that we would have here a more mysterious routine than these, and that we would like to know what for items are hold in the CX, SI etc. register on return from InitTask() without disassembling everything everywhere... how should we proceed?
 
 First of all let's see if the locations [0030] - [003A] are used elsewhere in our program... this is typical when you work with disassembled listings: to find out what one block of code
means, you need most of the time to look first at some other block of code. Let's see.. well, yes! Most of the locations are used again a few lines down (1.04F8 to 1.0508).
 
 Five words are being pushed on the stack as parameters to WinMain(). If only we knew what those enigmatic parameter were... but wait: we do actually know what those parameters are!
WinMain(), the function being called from this code, always looks like:
 
    int  PASCAL WinMain(WORD hInstance, WORD hPrevInstance,
          LPSTR lpCmdLine, int nCmdShow);
 
And we (should) know that in the Pascal calling convention, which is used extensively in Windows because it produces smaller code than the cdecl calling convention, arguments are pushed on the stack in the same order as they appear inside the function declaration. That's a good new for all little crackers!
 
 Thus, in our example, [0034] must be hInstance, [0032] must be hPrevinstance, [0038]:[0036] are segment and offset of lpcmdline and [003A] must be nCmdshow.
 
 What makes this important is that we can now go and replace *every* occurrence of [0034] by a more useful name such as hInstance, every occurrence of [0032] by hPrevInstance and so on. This clarify not just this section of the listing, but every section of the listing that refers to these variables. Such global substitutions of useful names for placeholder names or
addresses is indispensable when working with a disassembled listing. After applying these changes to the fragment shown earlier, we end up with something more understandable:

    1.04CB  890E3000                 mov     [0030], cx
  1.04CF  89363200                 mov     hPrevInstance, si
  1.04D3  893E3400                 mov     hInstance, di
  1.04D7  891E3600                 mov     lpCmdLine+2, bx
  1.04DB  8C063800                 mov     lpCmdLine, es
  1.04DF  89163A00                 mov     nCmdShow, dx
  1.04E3  33C0                     xor     ax, ax
  1.04E5  50                       push    ax
  1.04E6  9AFFFF0000               call    KERNEL.WAITEVENT
  1.04EB  FF363400                 push    word ptr hInstance
  1.04EF  9AFFFF0000               call    USER.INITAPP
  1.04F4  0BC0                     or      ax, ax
  1.04F6  741B                     je      0513
  1.04F8  FF363400                 push    word ptr hInstance
  1.04FC  FF363200                 push    word ptr hPrevInstance
  1.0500  FF363800                 push    word ptr lpCmdLine
  1.0504  FF363600                 push    word ptr lpCmdLine+2
  1.0508  FF363A00                 push    word ptr nCmdShow
  1.050C  E89FFE                   call    WinMain
 
  Thus if we didn't already know what InitTask() returns in various register (our Taskman here is only an example for your later work on much more mysterious target programs), we could
find it out right now, by working backwards from the parameters to WinMain().
 
Windows disassembling (and cracking) is like puzzle solving: the more little pieces fall into place, the more you get the global picture. Trying to disassemble Windows programs without this aid would be unhealthy: you would soon delve inside *hundreds* of irrelevant calls, only because you did not do your disassemble homework in the first place.
 
 It was useful to look at the startup code because it illustrated the general principle of trying to substitute useful names such as hPrevInstance for useless labels such as [0034].  But, generally, the first place we'll look examining a Windows program is WinMain(). Here the code from WCB:

  1.0492  5D                       pop     bp
  1.0493  C20A00                   ret     000A

  Let's begin from the last line: ret 000A. In the Pascal calling convention, the callee is responsible for clearing its arguments off the stack; this explains the RET A return. In this particular case, WinMain() is being invoked with a NEAR call. As we saw in the startup code, with the Pascal calling convention, arguments are pushed in "forward" order. Thus, from the prospective of the called function, the last argument always has the *lowest* positive offset from BP (BP+6 in a FAR call and BP+4 in a NEAR call, assuming the standard PUSH BP -> MOV BP,SP function prologue, like at the beginning of this WinMain().
 
 Now write the following in your cracking notes (the ones you really keep on your desk when you work... close to your cocktail glass): function parameters have *positive* offsets from BP,
local variables have *negative* offsets from BP.
 
 What does all this mean... I hear some among you screaming... well, in the case of WinMain(), and in a small-model program like Taskman, which starts from BP+4, you'll have:
 

int  PASCAL WinMain(HANDLE hInstance, HANDLE hPrevInstance,          LPSTR lpCmdLine, int nCmdShow);
nCmdShow       =         word ptr [bp+4]
lpCmdLine      =         dword ptr [bp+6]
hPrevInstance  =         word ptr [bp+0Ah]
hInstance      =         word ptr [bp+0Ch]

  Yeah... let's rewrite it:

  1.03B6  2BFF                 sub     di, di
  1.03B8  397E0A               cmp     hPrevInstance, di
  1.03BB  7405                 je      03C2
  1.03BD  2BC0                 sub     ax, ax
  1.03BF  E9CC00               jmp     048E

  1.03C2 >C47606               les     si, dword ptr lpCmdLine
  1.03C5  26803C00             cmp     byte ptr es:[si], 00

  We can now see, for example, that WinMain() checks if hPrevInstance is zero (sub di,di); if it isn't, it immediately jump to the pops and exits (jmp 048E).
 
 Look at the code of WinMain() once more... notice that our good Taskman appears to be inspecting its command line... funny: the Windows documentation says nothing about command line arguments to Taskman... Look around location 1.03D0 above, you'll see that
Taskman appears to be looking for a space (20h), getting a character from the command line, multiplying it by 10 (0Ah), subtracting the character zero (30h) and doing other things that seem to indicate that it's looking for one or more *numbers*. The code line 1.03E7 SUB ax,30h it's a typical code line inside many routines checking for numbers. The hex ascii code for numbers is 30 for 0 to 39 for 9, therefore the transmutation of an ascii code in hex *number* is pretty easy: mov al, your_number and sub ax,30... you'll find it very often.
 
 Rather than delve further into the code, it next makes sense to *run* taskman, feeding it different numbers on the command line, and seeing what it does (it's surprising how few crackers think of actually going in and *running* a program before spending much time looking at its code).
 
 Normally Taskman runs when you type CTRL+ESC in Windows, but its just a regular program, that can be run with a command line, like any other program.
 
 Indeed, running "TASKMAN 1" behaves differently from just running "TASKMAN": it positions the Task List in the upper-left corner of the screen, instead of in the middle. "TASKMAN 666 666" (the number of the beast?) seems to position it in the lower right corner.
 
 Basically, the command line numeric arguments seem to represent an (x,y) position for our target, to override its default position in the middle of the screen.  So you see, there are hidden 'goodies' and hidden 'secrets' even behind really trivial little programs like Taskman (and believe me: being able to identify this command line checking will be very useful ;-) when you'll crack applications and/or games that *always* have backdoors and hidden goodies).
 
 Back to the code (sip your favourite cocktail during your scrutinies... may I suggest a Traitor? -> see the legendary FraVia's cocktail page at, http://ourworld.compuserve.com/homepages/FraVia/cocktail.htm)... you can see that the variables [0010] and [0012] are being manipulated. What are these for?
 
 The answer is *not* to stare good and hard at this code until it makes sense, but to leave this area and see how the variables are used elsewhere in the program... maybe the code elsewhere will be easier to understand (for bigger applications you could in this case use a Winice breakpoint on memory range, but we'll remain with our WCB disassembly listing).
 
 In fact, if we search for data [0010] and [0012] we find them used as arguments to a Windows API function:

  1.018B >A31200           mov     [0012], ax
  1.018E  FF760E           push    word ptr [bp+0E]
  1.0191  FF361000         push    word ptr [0010]
  1.0195  50               push    ax
  1.0196  56               push    si
  1.0197  57               push    di
  1.0198  6A00             push    0000
  1.019A  9AFFFF0000       call    USER.MOVEWINDOW

This shows us *immediately* what [0010] and [0012] are. MoveWindows() is a documented function, whose prototype is:
 
 void FAR PASCAL MoveWindow(HWND hwnd, int nLeft, int nTop, int
nWidth, int nHeight, BOOL fRepaint);

   1.018B >A31200          mov     [0012], ax
  1.018E  FF760E          push    word ptr [bp+0E] ;hwnd
  1.0191  FF361000        push    word ptr [0010]  ;nLeft
  1.0195  50              push    ax                ;nTop
  1.0196  56              push    si                ;nWidth
  1.0197  57              push    di                ;nHeight
  1.0198  6A00            push    0000              ;fRepaint
  1.019A  9AFFFF0000      call    USER.MOVEWINDOW

  In other words, [0010] has to be nLeft and [0012] (whose contents have been set from AX) has to be nTop.   Now you'll do another global search and replace on your WCB
disassembly, changing every [0010] in the program (not just the one here) to nLeft, and every [0012] to nTop.   A lot of Windows cracking is this easy: all Windows programs seem to do is call API functions, most of these functions are documented and you can use the documentation to label all arguments to the function. You then transfer these labels upward
to other, possibly quite distant parts of the program.
 
 In the case of nLeft [0010] and nTop [0012], suddenly the code in WinMain() makes much more sense:

1.03C2 >C47606      les     si, dword ptr lpCmdLine
1.03C5  26803C00    cmp     byte ptr es:[si], 00 ; no cmd line?
1.03C9  7453        je      041E        ; go elsewhere
1.03CB  897EF2      mov     [bp-0E], di
1.03CE  EB1E        jmp     03EE
1.03D0 >26803C20    cmp     byte ptr es:[si], 20 ; if space
1.03D4  741E        je      03F4        ; go elsewhere
1.03D6  B80A00      mov     ax, 000A
1.03D9  F72E1000    imul    nLeft       ;nleft *= 10
1.03DD  A31000      mov     nLeft, ax
1.03E0  8BDE        mov     bx, si
1.03E2  46          inc     si
1.03E3  268A07      mov     al, es:[bx]
1.03E6  98          cbw                 ; ax = char
1.03E7  2D3000      sub     ax, 0030    ; ax='0' (char-> number)
1.03EA  01061000    add     nLeft, ax   ; nleft += number
1.03EE >26803C00    cmp     byte ptr es:[si], 00 ;NotEndOfString
1.03F2  75DC        jne     03D0        ;next char
...
 
In essence, Taskman is performing the following operation here:
   static int nLeft, nTop;
     //...
     if (*lpCmdLine !=0)
     sscanf(lpCmdLine, "%u %u, &nLeft, &nTop);
 
Should you want 3.1. Taskman to appear in the upper left of your screen, you could place the following line in the [boot] section of SYSTEM.INI:
 
    taskman.exe=taskman.exe 1 1
 
In addition, doubleclicking anywhere on the Windows desktop will bring up Taskman with the (x,y) coordinates for the double click passed to Taskman on its command line.  The USER!WM_SYSCOMMAND handler is responsible for invoking Taskman, via WinExec() whenever you press CTRL+ESC or double click the desktop.
 
What else is going on in WinMain()? Let's look at the following block of code:

1.041E >6A29         push    0029
1.0420  9AF9000000   call    USER.GETSYSTEMMETRICS
1.0425  50           push    ax
1.0426  1E           push    ds
1.0427  681600       push    0016
1.042A  9AFFFF0000   call    KERNEL.GETPROCADDRESS
1.042F  8946F4       mov     [bp-0C], ax
1.0432  8956F6       mov     [bp-0A], dx
1.0435  0BD0         or      dx, ax
1.0437  7407         je      0440
1.0439  6A01         push    0001
1.043B  6A01         push    0001
1.043D  FF5EF4       call    far ptr [bp-0C] ;*1 entry

 The lines push 29h & CALL GETSYSTEMMETRICS are simply the assembly language form of GetSystemMetrics(0x29). 0x29 turns out to be SM_PENWINDOWS (look in WINDOWS.H for SM_).
 
Thus, we now have GetSystemMetrics(SM_PENWINDOWS). If we read the documentation, it says that this returns a handle to the Pen Windows DLL if Pen Windows is installed. Remember that 16-bit return values *always* appear in the AX register.

Next we can see that AX, which must be either 0 or a Pen Window module handle, is pushed on the stack, along with ds:16h.  Let's immediately look at the data segment, offset 16h:

2.0010  0000000000005265  db  00,00,00,00,00,00,52,65 ; ......Re
2.0018  6769737465725065  db  67,69,73,74,65,72,50,65 ; gisterPe
2.0020  6E41707000000000  db  6E,41,70,70,00,00,00,00 ; nApp....

Therefore:
2.0016  db 'RegisterPenApp',0

Thus, here is what we have so far:
     GetProcAddress(
          GetSystemMetrics(SM_PENWINDOWS),
          "RegisterPenApp")

  GetProcAddress() returns a 4 bytes far function pointer (or NULL) in DX:AX. In the code from WinMain() we can see this being moved into the DWORD at [bp+0Ch] (this is 16-bit code, so moving a 32-bit value requires two operations).   It would be nice to know what the DWORD at [bp-0Ch] is. But, hey! We *do* know it already: it's a copy of the return value from GetProcAddress(GetSystemMetrics(SM_PENWINDOWS), "RegisterPenApp)! In other words, is a far pointer to the RegisterPenApp() function, or NULL if Pen Windows is not
installed. We can now replace all references to [bp-0Ch] with references to something like fpRegisterPenApp.
 
Remember another advantage of this "dead" Windows disassembling vis-a-vis of the Winice approach "on live": here you can choose, picking *meaningful* references for your search and replace operations, like "mingling_bastard_value" or "hidden_and_- forbidden_door". The final disassembled code my become a work of art and inspiration if the cracker is good! Besides, *written* investigations will remain documented for your next cracking session, whereby with winice, if you do not write everything down immediately, you loose lots of your past work (it's incredible how much place and importance retains paper in our lives).
 
After our search and replaces, this is what we get for this last block of code:
    
 FARPROC fpRegisterPenAPP;
     fpRegisterPenApp = GetProcAddress(
          GetSystemMetrics(SM_PENWINDOWS),
          "RegisterPenApp");

Next we see  [or dx, ax] being used to test the GetProcAddress() return value for NULL. If non-NULL, the code twice pushes 1 on the stack (note the PUSH IMMEDIATE here... Windows applications only run on 80386 or higher processors... there is no need to place the value in a register first and then push that register) and then calls through the fpRegisterPenApp function pointer:

1.0435  0BD0         or      dx, ax
1.0437  7407         je      0440
1.0439  6A01         push    0001
1.043B  6A01         push    0001
1.043D  FF5EF4       call    dword ptr fpRegisterPenApp

  Let's have a look at the Pen Windows SDK doucmentation (and PENWIN.H):
     #define RPA_DEAFULT
void FAR PASCAL RegisterPenApp(UINT wFlags, BOOL fRegister);

Simply by looking up API calls in the Windows documentation (get it, you'll need it continuously to crack successfully), we can turn the whole block of assembly language code into this:

void (FAR PASCAL *RegisterPenApp) (UINT,BOOL);
RegisterPenApp = GetProcAddress(
   GetSystemMetrics(SM_PENWINDOWS),
   "RegisterPenApp");
 if (RegisterPenApp != 0)
     (*RegisterPenApp) (RPA_DEFAULT, TRUE);

 We can continue in this way with all of WinMain(). When we are done, the 100 lines of assembly language for WinMain() boild own to the following 35 lines of C code:

// nLeft, nTop used in calls to MoveWindow() in TaskManDlgProc()
 static WORD nLeft=0, nTop=0;
   BOOL FAR PASCAL TaskManDlgProc(HWND hWndDlg, UINT msg, WPARAM
    wParam, LPARAM lParam);
   int PASCAL WinMain(HANDLE hInstance, HANDLE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow)
 {
  void (FAR PASCAL *RegisterPenApp) (UINT,BOOL);
  FARPROC fpDlgProc;
  if (hPrevhInstance != 0)
     return 0;
  if (*lpCmdLine !=0 )
     _fsscanf(lpCmdLine, "%u %u, &nLeft, &nTop); // pseudocode
 RegisterPenApp = GetProcAddress(GetSystemMetrics(SM_PENWINDOWS),
  "RegisterPenApp");
 if (RegisterPenApp != 0)
     (*RegisterPenApp) (RPA_DEFAULT, TRUE);
 if (fpDlgProc = MakeProchInstance(TaskManDlgProc, hInstance))
  {
     DialogBox(hInstance, MAKEINTRESOURCE(10), 0, fpDlgProc);
     FrreProcHInstance(fpDlgProc);
  }
 if (RegisterPenApp != 0)
     (*RegisterPenApp) (RPA_DEFAULT, FALSE);
   return 0;
 }
In this lesson we had a look at WinMain()... pretty interesting, isn't it? We are not done with TASKMAN yet, though... we'll see in the next lessons wich windows and dialog procedures TASKMAN calls.
