Own/User defined Icon on Messagebox

[bloodhound]

how do you do this?? instead of ICON_INFORMATION, etc etc..
you load your own icon on the messagebox

or you just create a child window?

[hutch--]

Can't be done in a normal message box. Give the following code a blast, you can set your own icon this way.

Code Select Expand


; ¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤

MessageBoxI proc hParent:DWORD,lpMsg:DWORD,
             lpTitle:DWORD,dlgStyle:DWORD,iconID:DWORD

    LOCAL mbp:MSGBOXPARAMS

    mov mbp.cbSize, SIZEOF MSGBOXPARAMS
    mov eax, hParent
    mov mbp.hwndOwner, eax
    mov eax, hInstance
    mov mbp.hInstance, eax
    mov eax, lpMsg
    mov mbp.lpszText, eax
    mov eax, lpTitle
    mov mbp.lpszCaption, eax
    mov eax, dlgStyle
    or eax, MB_USERICON
    mov mbp.dwStyle, eax
    mov eax, iconID
    mov mbp.lpszIcon, eax
    mov mbp.dwContextHelpId, NULL
    mov mbp.lpfnMsgBoxCallback, NULL
    mov mbp.dwLanguageId, NULL

    invoke MessageBoxIndirect,ADDR mbp

    ret

MessageBoxI endp

; ¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤=÷=¤

Thanks hutch-- ,will try it  :U

[Vortex]

Hutch, you should add this procedure to masm32.lib :U

Erol,

I was supposed to, I just forgot.  ::)

[Vortex]

Hutch,

I added the missing hInstance parameter to your procedure :

Code Select Expand

MessageBoxI PROC hInstance:DWORD,hParent:DWORD,lpMsg:DWORD,lpTitle:DWORD,\
                 dlgStyle:DWORD,iconID:DWORD


Attached is a quick example.

Thanks Vortex!  :U

Vortex is right, I normally set hInstance as a global but it should properly be self contained so it remains as close as possible to the normal MesageBox API call. I have attached a simple demo on how it works with the minor change.
