Topic created on: March 22, 2013 16:05 CDT by drew77 .

I have a small program that displays a dialog box that requires clicking on Next to continue.

I used Ollydbg, but I can't find the dialog box so I can jmp past it.

Can someone help me ?

thanks.

This is what I have so far.

I am modifying some code I found, and there are things missing.

I will start a program and then send keystrokes to it so it goes unattended.

I need some help in where the code after WindowName goes.

I just noticed that some data is missing too.

.data
SuNam  db  "chklnks",0

.data?

.code

start:

; Start chklnks first

; get the full name and the handle

WindowName Proc  ; FNameAdr:DWord,FHandle:DWord
         Local A, X, Y, Z:DWord
         mov    FHandle,0
         mov    Z,0        ; GW_HWNDFIRST
         Op2ToOp1 X,hwnd
         .while X>0
           invoke GetWindow, X, Z
           mov  X,eax
           mov  Z,2 ; GW_HWNDNEXT
           .if  X>0
             invoke GetWindowLongA, X, -6 ; GWL_HINSTANCE
             mov Y,eax
             .if Y>0
               ; get (consecutive) the names of active applications
               invoke GetWindowText,X,addr FName, 100
               ; lookup in proc "InstrStr" for the String (in SuNam) if found in FName
               invoke InstrStr, addr SuNam,addr FName,1
               ; if the name starts in position 1 in addr FName: name has been found, termin. loop
               .if eax==1
                 mov eax,X
                 mov FHandle,eax
                 mov  X,0  ; beende Schleife
               .endif
             .endif
           .endif
         .endw

         ; full name of application is in addr FName, handle to the application is in FHandle
         .if   eax==0
           mov FName,0 ; clear if not found  Application has not been started yet
         .endif
         ret
WindowName Endp

; and hier the part for sending Alt+F4
         invoke GetForegroundWindow  ; save handle of own window
         mov    hwndTemp,eax

         invoke SetForegroundWindow, FHandle ; activate VirtualDub-window
         ; and now simulate keyboard entries
        
         invoke keybd_event, VK_RETURN, NULL, NULL, NULL ; Send ENTER key
         invoke Sleep, 7000 ; give enuf time to find bad links
        
         invoke keybd_event, VK_TAB, NULL, NULL, NULL ; Send tab key
         invoke Sleep, 1500
        
         invoke keybd_event, VK_TAB NULL, KEYEVENTF_KEYUP, NULL ; Send F4 key 'up'
         invoke Sleep, 1500
        
         invoke keybd_event, VK_RETURN, NULL, NULL, NULL ; Send ENTER key
         invoke Sleep, 1500

         invoke keybd_event, VK_RETURN, NULL, NULL, NULL ; Send ENTER key
         invoke Sleep, 1500
  
        
         invoke SetForegroundWindow, hwndTemp  ; activate own window again

end     start

Can you extend or rephrase the question?

As I understand it, you've got a little program (a crackme of sorts) where you want to remove a Nag-Screen.

For the removal of this nag-screen you've wrote this application in Assembler (the code) to auto-click it as you couldn't find the code to jump over or nop-out in the CracKMe?

Can you point me to the right direction? So you can help me help you :)

The program is chklnks.exe.

I want to be able to inject Tabs and Enter so the program will run by itself.

I hope that made it more clear.

I can upload a copy of the program if that would help.
