hi,
how to create system modal windows or dialog boxes? with system modal i mean, that first the window or dialog must be closed before you can do anything else.
I believe with DialogBoxes you can define the system modal in the resource with DS_MODALFRAME.
For Windows' tho... isn't it enough to declare the hWndParent thingy?
Maybe I'm wrong, maybe not... at least I tried...
:) Jimmy
what do you mean with that "hwndparent" thingy? could you explain that a bit?
and it isn't enough to declare DS_MODALFRAME in the resource. this is my template:
MyDialog DIALOG 10, 10, 205, 60
STYLE 0x0004 | DS_CENTER | WS_CAPTION |
WS_VISIBLE | DS_MODALFRAME | DS_3DLOOK | DS_SYSMODAL | WS_POPUP | WS_SYSMENU
Hi Safcon,
Sorry for pointing you in the wrong direction. Actually I thought it was easy but trying it showed me the opposite.
Well, ok. There's only one way I found out how I could get a dialog modal so that no other message was processed by the main window while it was on screen. This of course is a sh*tty solution (and I'm not proud of it)
I configured my dialog as DS_MODALFRAME (I think this is useless anyhow) but more importantly WS_CHILD (Side-effect: It can't leave your mainwindow) The I inserted a Flag before the Wndproc
.data
Flag byte 0
.code
WndProc proc hWin :DWORD,
uMsg :DWORD,
wParam :DWORD,
lParam :DWORD
.while Flag!=0
return 0
.endw
...
...
.if uMsg==WM_COMMAND
invoke CreateDialogParam,hInstance,ADDR dialog,hWin,ADDR DialogProc,NULL
.ELSEIF etc etc
...
...
WndProc endp
DialogProc proc hwnd:HWND, iMsg:DWORD, wParam:WPARAM, lParam:LPARAM
.IF iMsg==WM_INITDIALOG
mov Flag,1
.ELSEIF iMsg==WM_CLOSE
mov flag,0
invoke EndDialog,hwnd,NULL
.ELSE
mov eax,FALSE
ret
.ENDIF
mov eax,TRUE
ret
DialogProc endp
There is no such thing as system modal in Win32. Any existing (remaining) styles or functions are provided for porting compatibility from Win16.
If you need a window to stay on top, ie, even if another window is enables, it is still drawn behind the 'on top window'. call SetWindowPos and set the HWND_TOPMOST flag or something in the zOrder. I also think there might be a flags to do this in dwStyleEx or dwStyle.
Safcon,
U gotta love to hear it :)
