Hi,

You can use the following Macro ,

ON_UPDATE_COMMAND_UI( MENU_ID, memberFxn ) and in the definition

void memberFxn( CCmdUI* pCmdUI )
{

pCmdUI->Enable(false);
}

Regards,

vinsankar

See In my MFC program, I'm trying to disable a menu item with EnableMenuItem(), but it doesn't have any effect on the menu. Why[^]

how to use HWND provided by SPY++ in my Application [modified]

Re: how to use HWND provided by SPY++ in my Application

15-Dec-06 22:30

hi ok as guys are not able to understand what i am asking i will try to be specific

run spy++ and in windows section(ctrl+w) you see different windows handel values,
i want to use one of those value in my program and send a message to that particular window, defined by the window handel id,

exm:
in spy++ one appliction window has id 2222
i want to send message to 2222 window handel id
how to do tht,
as far i know u simply cant do like this HWND h=2222;

my app
for suppose there is xyz window or application, i query for HWND in Spy++, it returns me 2222, i want to use tht value in my application to send a message to tht window,
SendMessage( hwnd a, ...,...,...);
how to do hwnd a = 2222;

any idea or suggestion,
the basic doubt is how to use a handel value provided by spy++, if app does nt have a window or a hidden application or tray icon.

You can use this value as handle in SendMessage.

How would you get handle , if there is no window ?

Actually he can, if the app has the window hidden.

As said earlier. You can use SendMessage. if you have handle to that window. No matter if its hidden.

Mentioning SPY++ from start leads to confusion. You can look in to this[^] article, to see how to get windows handle.

Alternatively, you can use FindWindow() , if you have title to window in question.

no i dont want sample for spy, i can make spy++,
1st ? can there be a window with out name
2nd dont u think there are windows or application who has a window but hidden.
so in tht case how to get there handel
you query in SPY++ and you come to know about the handel value
now you want to hard code tht value in your app and send some message

for this do u have any idea or it cant be done ?

Yes, But I was concerned about "if application does not have window" statement.

In fact, his words where a bit inaccurate. Anyway what he was asking was enough clear, at least to me...

It was not clear, atleast for me .. Smile | :)

I was assuming from start, he has way to get window handle. But he was asking for it in actual.

Hi everybody,

I have encountered a strange problem, and I don't even know why it is happening. Anyways, I have a dialog box that has a progress bar, and some static controls that show the elapsed time, percentage...and such. Now, I start a new thread and do the work, and update the static controls with SetDlgItemText (this is no MFC app, just Win32 and ATL). Now the static controls displays the text correctly only the first time, and later on the new text draws over the previous one, and after a while static controls just show a complete mess! I discovered that if I open any other window in front of my window, and then move it away, the static controls will briefly show the text correctly, but then again is the same. I suppose it got something to do with the messages those controls are receiving, but can't figure out why. It is as if the controls are drawing the text, but not deleting the previous one.

Thank you.

You could try forcing a repaint by calling

::InvalidateRect(hwdDlg, NULL, TRUE);
::UpdateWindow(hwdDlg);

each time you update the status (change the controls).

Why InvalidateRect or UpDateWindow didnt work?

I really don't know. This is what I have done:

::InvalidateRect( hWndPercent, NULL, TRUE );
::UpdateWindow( hWndPercent );

If I do this:

Invalidate(TRUE)

then the static controls are displaying text correctly, but I am redrawing the whole dialog so I also have a terrible flickering.

Thanks.
