recolor my stockobject

[Younth]

Hi !
There is a little problem in my process,i used a local variable (asd) to determine how to recolor my stockobject,but It seems not effective at all
here the codes:

_ShowTimec   proc uses ebx _hWnd,_hDC, asd:DWORD
      local   @stTime:SYSTEMTIME

      pushad
      invoke   GetLocalTime,addr @stTime
      invoke   _CalcClockParam
                     .if asd==1
         invoke   GetStockObject,LTGRAY_BRUSH
                               .else
                                   invoke      GetStockObject,BLACK_BRUSH
                               .endif
      invoke   SelectObject,_hDC,eax
      invoke   _DrawDot,_hDC,360/12,3   ;draw12 big points
      invoke   _DrawDot,_hDC,360/60,1   ;drawing 60 little points
                     .if asd==1
       invoke   CreatePen,PS_SOLID,1,0
                               .else
                                 invoke      CreatePen,PS_SOLID,1,245
                               .endif
      invoke   SelectObject,_hDC,eax
      invoke   DeleteObject,eax
      movzx   eax,@stTime.wSecond
      mov   ecx,360/60
      mul   ecx         ;seconddegree = second * 360/60
      invoke   _DrawLine,_hDC,eax,15
      .if asd==1
      invoke   CreatePen,PS_SOLID,2,0
                                .else
                                 invoke      CreatePen,PS_SOLID,2,245
                               .endif

      invoke   SelectObject,_hDC,eax
      invoke   DeleteObject,eax
      movzx   eax,@stTime.wMinute
      mov   ecx,360/60
      mul   ecx         ;minute =minute* 360/60
      invoke   _DrawLine,_hDC,eax,20
      .if asd==1
      invoke   CreatePen,PS_SOLID,5,0
                                .else
                                    invoke      CreatePen,PS_SOLID,5,245
                                 .endif

      invoke   SelectObject,_hDC,eax
      invoke   DeleteObject,eax
      movzx   eax,@stTime.wHour
      .if   eax >=   12
         sub   eax,12
      .endif
      mov   ecx,360/12
      mul   ecx
      movzx   ecx,@stTime.wMinute
      shr   ecx,1
      add   eax,ecx
      invoke   _DrawLine,_hDC,eax,30  ;hoursdegree=(hours%12)\12*360+分/60*30
      invoke   GetStockObject,NULL_PEN
      invoke   SelectObject,_hDC,eax
      invoke   DeleteObject,eax
      popad
      ret

_ShowTimec   endp


the codes in WinProc

local asd:DWORD
MOV asd,1

.if eax==WM_CHAR
                  push wParam
                  pop  @char
            .if wParam==99             ;char "c"
                     .if asd==1
                     mov asd,0
                     .else
                     mov asd,1
                     .endif
                   invoke   BeginPaint,hWinMain,addr @stPS
                   invoke _ShowTimec,hWinMain,eax,asd
                   invoke   EndPaint,hWinMain,addr @stPS
            .endif
and i'm sure on the other place,i have never changed or used this local variable(asd)
when i bulid them all, there was no warnings or errors
who can help me ?

Because it's a local variable, once your wndproc returns it is gone. Use a global variable (in .data or .data?) and it will keep its value in between calls to your wndproc.

 Yeah ! You're quite right
I fogot the winproc is just a function ,too. the gloable asd make it works .the real main function (like the main() in C or C++) is controled by these codes
:
.while   TRUE
         invoke   GetMessage,addr @stMsg,NULL,0,0
         .break   .if eax   == 0
         invoke   TranslateMessage,addr @stMsg
         invoke   DispatchMessage,addr @stMsg
      .endw

Is that right ?
Thank you ,sinsi, and  also your answering so soon ! haha  :clap:

Yes, that is your process's message loop (message pump), you tell the window manager to 'dispatch' the message to the wndproc of the right one of your windows.
