confused by a masm default example

\masm32\examples\exampl09\tables

Any Explaination would be appreciate.
I get the main point but puzzled by some sentences and usage.

1.
checkarray MACRO cnt1,cnt2,spc,lft,top:REQ
LOCAL idnum,hstep,vstep,lspc,stcnt,var
idnum = 500
stcnt = 400
hstep = 0
vstep = 0
REPEAT cnt1
DlgStatic 0,SS_RIGHT,3,top+vstep,15,8,stcnt
stcnt = stcnt + 1
REPEAT cnt2
DlgCheck 0,0,lft + hstep,top + vstep,8,8,idnum
idnum = idnum + 1
hstep = hstep + spc
ENDM
vstep = vstep + spc
hstep = 0
ENDM
ENDM

2.
mov hInstance, FUNC(GetModuleHandle,NULL) ---- FUNC() ?

3.
main proc ---- What's the habit/usage to create window? Why not use .rc file?

Dialog "Create Character Table", \ ; caption
"MS Sans Serif",10, \ ; font,pointsize
WS_OVERLAPPED or \ ; styles for
WS_SYSMENU or DS_CENTER, \ ; dialog window
256 + 16 + 8, \ ; number of controls
50,50,203,240, \ ; x y co-ordinates
32768 ; memory buffer size

DlgButton "Numbers", WS_TABSTOP, 21,185,50,13,100

4.
CallModalDialog hInstance,0,DlgProc,NULL ---- CallModalDialog? Where is the defination?
free pMem

5.
mov str1, ustr$(ccntr) ---- ustr$(ccntr) ?
fn SetWindowText,FUNC(GetDlgItem,hWin,nrange),str1 ---- fn?
mov str1,cat$(str1,"Ascii ",str$(ctrl)," Hex ",right$(hex$(ctrl),2)," Character ",str2)

1.
checkarray MACRO cnt1,cnt2,spc,lft,top:REQ
LOCAL idnum,hstep,vstep,lspc,stcnt,var
idnum = 500
stcnt = 400
hstep = 0
vstep = 0
REPEAT cnt1
DlgStatic 0,SS_RIGHT,3,top+vstep,15,8,stcnt
stcnt = stcnt + 1
REPEAT cnt2
DlgCheck 0,0,lft + hstep,top + vstep,8,8,idnum
idnum = idnum + 1
hstep = hstep + spc
ENDM
vstep = vstep + spc
hstep = 0
ENDM
ENDM

This macro simplifies the creation of a large ammount of controls (just to save typing). It creates a collection of controls, a single static followed by cnt2 Check Boxes. This is done cnt1 times each time shifting down in order to create a table.

2.
mov hInstance, FUNC(GetModuleHandle,NULL) ---- FUNC() ?

FUNC is a macro defined in MACROS.ASM, it returns the value in EAX after a call to INVOKE:

FUNC MACRO parameters:VARARG
invoke parameters
EXITM <eax>
ENDM

3.
main proc ---- What's the habit/usage to create window? Why not use .rc file?

Dialog "Create Character Table", \ ; caption
"MS Sans Serif",10, \ ; font,pointsize
WS_OVERLAPPED or \ ; styles for
WS_SYSMENU or DS_CENTER, \ ; dialog window
256 + 16 + 8, \ ; number of controls
50,50,203,240, \ ; x y co-ordinates
32768 ; memory buffer size

DlgButton "Numbers", WS_TABSTOP, 21,185,50,13,100

This simplifes the creation of in memory dialogs. You could have created your dialogs in a RC file, but this is how the author decided to create his dialogs. I've not sat down and tested any of that code out but looking DIALOGS.INC I would say that it probably loads up a lot faster than having to find, load, then call a dialog resource. NTM if you didn't have any other resources it could allow you to cut out the resource section all together.

4.
CallModalDialog hInstance,0,DlgProc,NULL ---- CallModalDialog? Where is the defination?
free pMem

CallModalDialog is another one of the routines found in Dialogs.inc for in memory dialogs.


    ; ------------------------------------
    ; create a modal dialog from the data
    ; written to the memory template.
    ; ------------------------------------
      CallModalDialog MACRO Instance,Parent,DlgProc,lpExtra
        invoke DialogBoxIndirectParam,Instance,esi,Parent,
                                      ADDR DlgProc,lpExtra
        push eax                ;; preserve return value
        invoke GlobalFree,esi   ;; free memory
        pop eax                 ;; restore return value
        pop edi
        pop esi
      ENDM

5.
mov str1, ustr$(ccntr) ---- ustr$(ccntr) ?
fn SetWindowText,FUNC(GetDlgItem,hWin,nrange),str1 ---- fn?
mov str1,cat$(str1,"Ascii ",str$(ctrl)," Hex ",right$(hex$(ctrl),2)," Character ",str2)

ustr$ - converts a string to an unsigned integer
fn - like INVOKE except it lets you use quoted strings
cat$ - catconates strings together
str$ - converts a dword value to a string
hex$ - converts a dword to a hex string

Re: confused by a masm default example

THX Synfire, I got it! :D

almost everything in the dialogs.inc and macros.asm, and also the hlhelp.hlp :D

Re: confused by a masm default example

There is a question about the AutoCheckBox:

the macro define 256 autocheckbox

      checkarray MACRO cnt1,cnt2,spc,lft,top:REQ	; checkarray 16,16,10,22,20
        LOCAL idnum,hstep,vstep,lspc,stcnt,var
          idnum = 500
          stcnt = 400
          hstep = 0
          vstep = 15
        REPEAT cnt1		; cnt1=16
          DlgStatic 0,SS_RIGHT,3,top+vstep,15,8,stcnt	; static control, ty=top+vstep=20
          stcnt = stcnt + 1
            REPEAT cnt2				; cnt2=16
              DlgCheck 0,0,lft + hstep,top + vstep,8,8,idnum		; check box, tx=lft+hstep=22
              idnum = idnum + 1
              hstep = hstep + spc			; spc=10
            ENDM
          vstep = vstep + spc
          hstep = 0
        ENDM
      ENDM

I just want to SetTimer when the 1st(any of the 256) autocheckbox checked, but I don't know how to use the BN_CLICKED notification. I use it below but failed:

      Case WM_COMMAND
        Switch wParam
          Case IDOK                       ; clear
            mov nrange, 500
            .while nrange <= 755
              invoke SendMessage,FUNC(GetDlgItem,hWin,nrange),BM_SETCHECK,BST_UNCHECKED,0
              add nrange, 1
            .endw
          Case IDCANCEL
            jmp quit_dialog
          Case BN_CLICKED
            mov eax,wParam
           mov nrange, 500
            .while nrange <= 755
              invoke  IsDlgButtonChecked,FUNC(GetDlgItem,hWin,nrange),nrange
              .if	eax == BST_CHECKED
              	invoke  SetTimer,hWin,ID_TIMER,5000,NULL
              jz	@F
              .endif
              add nrange, 1
            .endw						
            @@:
          Default
       	
        EndSw

Re: confused by a masm default example

For BN_CLICKED notification wParam consists of notification message id(hiword of wParam) and a control id(loword of wParam).
So your code check wParam against BN_CLICKED meanwhile wParam is something like that : (BN_CLICKED shl 16) or CTRLID.

Re: confused by a masm default example

I tried it several times but failed! :sad:
I get the BN_CLICKED but how can I receive the message and SetTimer when the 1st(any of the 256) autocheckbox checked for that there is no actual handle of them.

any snipplet would be appreciate. I'm really puzzled. :shock:
Thanks in advanced.

Re: confused by a masm default example

Eric4ever,
Now comes the testing since you have the basic code. I would use a MessageBox to trace results to make sure the flow is according to Hoyle. Move the MessageBox around and with it, you will quickly get to the bottom of it. I am not a fan of this high level approach as it is hard to see what is going on with func, switch and case, etc. Perhaps I am to old fashioned.

Anyway, please keep us posted as I, for one, am interested. Do not forget to shift wParam or you will never get there.

Paul
