         .endif
        .endif

.elseif eax==WM_VSCROLL
invoke SendDlgItemMessage,hWin,IDC_EDT12,WM_SETTEXT,0,addr outpos_buff_9

like I said program is working , values in spinner control are going up or down by 0.250 , but  :dazzled:
the problem is when I add second spin control(same code like this) and new line for that control in WM_VSCROLL , like this

.elseif eax==WM_VSCROLL

invoke SendDlgItemMessage,hWin,IDC_EDT12,WM_SETTEXT,0,addr outpos_buff_9
invoke SendDlgItemMessage,hWin,IDC_EDT13,WM_SETTEXT,0,addr outpos_buff_10

when user click up or down arrow on one control ,
other control is automaticly empty...
I know thats because other control buff is empty ( there wasnt any clicking yet),
my question is how I can control that...


btw both controls getting their default values like this:
.if eax==WM_INITDIALOG
invoke SendDlgItemMessage,hWin,IDC_EDT12,WM_SETTEXT,0,addr df_spin12
invoke SendDlgItemMessage,hWin,IDC_EDT13,WM_SETTEXT,0,addr df_spin13

thx

Glad to hear that. (Also nice to see some use for the Fpulib.)

my question is how I can control that...

That is quasi-impossible to answer without seeing most of the code you used. Zip it up, including the resource file, and I will have a look at it.

I find FpuLib very very helpful...

:U

this is download link for small program that shows exactly what is the problem,
btw I put all RadAsm project in it ( 8kb )...

Please, what must I use to access the information inside that .7z file????? :dazzled: :dazzled: :dazzled:

I just notice some strange behavior of spin control in this program,
when you click up or down arrow ( I mean no clicking but one click and keep it press ) values want go
for their max or min but only for 3.75 points ( + or - , depends if you click up or down ) and it will
stop...
I dont see any limitations in program that can cause that ...!

@raymond
sry...
I'm using 7-Zip for a long time and I thought that newest versions of WinRar and WinZip
can open *.7z file...
If you have trouble with it I will post link with *.rar or *.zip file...
thx

Thanks for the link.

Initialize your outpos_buff buffers with the default values when processing the WM_INITDIALOG message.

Instead of checking if EAX=1 or -1, try checking if EAX is positive or negative instead.

test eax,eax
.if !SIGN?     ;if positive
   ....
.else          ;if negative
   ....
.endif

I would also suggest you increase the size of the edit boxes so that the entire number can be displayed.
