heya all, im quite a newbie in programming in asm .. so i would really need some help with this : i dont know how to load an image and an icon .. this the code :

Code:

format PE GUI 4.0
entry start

include 'win32a.inc'

WM_COMMAND1        = 109
ID_EXIT            = 105
ID_NAME            = 103
ID_SERIAL          = 104
ID_GENERATE        = 201
ID_CAPTION         = 101
ID_CAPTION1        = 102

section '.code' code readable executable

  start:
        invoke  GetModuleHandle,0
        invoke  DialogBoxParam,eax,37,HWND_DESKTOP,DialogProc,0
        invoke  ExitProcess,0


proc DialogProc hwnddlg,msg,wparam,lparam
        push    ebx esi edi
        cmp     [msg],WM_COMMAND
        je      wmcommand
        cmp     [msg],WM_CLOSE
        je      wmclose
        cmp     [msg],WM_COMMAND1
        je      wmclose
        xor     eax,eax
        jmp     finish


 wmcommand:
        cmp     [wparam],BN_CLICKED shl 16 + ID_EXIT
        je      wmclose
wmcommand1:
        cmp     [wparam],BN_CLICKED shl 16 + ID_GENERATE
        jne     finish
        cmp     [chg],1
        je      finish
        mov     [chg],1
        invoke  GetDlgItemText,[hwnddlg],ID_CAPTION,namebuffer
        invoke  SetDlgItemText,[hwnddlg],ID_CAPTION1,inputserial
        mov     [chg],0
        jmp     finish


  wmclose:
        invoke  EndDialog,[hwnddlg],0

  finish:
        pop     edi esi ebx
        ret

endp

for moving without caption

Code:

        cmp     ax,WM_LBUTTONDOWN
        jz      .move

  .move:
        invoke  ReleaseCapture
        invoke  SendMessage,[hWnd],WM_NCLBUTTONDOWN,HTCAPTION,NULL
        jmp     .processed

for load simple bmp's you can use LoadBitmap and for icons you can use LoadIcon

Code:

        push    ebx esi edi
        cmp     [msg],WM_COMMAND
        je      wmcommand
        cmp     [msg],WM_CLOSE
        je      wmclose
        cmp     [msg],WM_COMMAND1
        je      wmclose
        xor     eax,eax
        jmp     finish
        cmp     ax,WM_LBUTTONDOWN
        jz      .move

must be

Code:

        push    ebx esi edi
        cmp     [msg],WM_COMMAND
        je      wmcommand
        cmp     [msg],WM_CLOSE

        cmp     ax,WM_LBUTTONDOWN
        jz      .move 
        cmp     [msg],WM_COMMAND1
        je      wmclose
        xor     eax,eax
        jmp     finish

HTCAPTION is 2, not 56. http://board.flatassembler.net/topic.php?t=4015 has those missing constants for future reference.

and

Code:

cmp     ax,WM_LBUTTONDOWN

should be

Code:

cmp     [msg],WM_LBUTTONDOWN

I'll use this thread to ask some question about bitmaps too.

* I want a bitmap to act as a button. So, I add it to my dialog and make it answer to clicks. Now, how can I change it when mouse is over it and when user clicked it?

Example:
1) I have a button in gray, black and white colors.
2) When user place the mouse in it, it changes to another picture that is colored.
3) When the user click it, it changes the picture to another one that gives the effect of button pressed.
4) When mouse leaves the bitmap, it changes to the original gray, black and white one.
Any ideas?
