Hi friends

i have a windows service which is updating time data in a file (like 01:20). When I change system time in Windows Date and Time Property , the timing changes are reflected in the file by my service. But I change the time zone tab, the modified time it is not reflected in the file by my service. Windows Time is changed in SysTray icon. Why is not changed in my service ? D'Oh! | :doh:

i use localtime()

I think it is because the service is independent of the current logged-in user. You know that services cannot even read registry values in the HKEY_CURRENT_USER hive.
So my guess is that it (the service) does not care whether you change the regional settings or not. Because it does not even know you (the current user) Smile | :)

this is this.

Little Exception you can read it from HKEY_USER hives

CTRL + TAB.. Who handle this?

Hi,
Iam developing an Windows based application, where there are multiple browser windows opened. And when i press CTRL + TAB it shifts to the previous browser(the way in which ) it works in Visual Studio. But my question is:
1) Does windows (i mean the MFC or MFC's API)itself remebers this (the previous active frame window )?
2) If yes, then how and where is this information stored by the window so that i can dosome processing on it?

thanks in advance,

KAB

AFAIK, The OS manages this for you.

I'm not sure it stores it so you can get to it. (If you find otherwise, please let me know)

Window activation (OnActivate in MFC, or WM_ACTIVATE) is probably a good place to start

Hi all

I have created a MFC SDI application.

i have derived the view class from the CHtmlView class and used the LoadFromResource() to load the html page into the view.

Now there were quite a few things that i wanted to stop for ex:

-------) stop the context menu to be displayed when mouse is right clicked on the html page.
-------) stop the mouse selection for the html content.
-------) stop the mouse cursor change over the static text.

All these problems are solved by adding some code in the html page inside the tag.

There is one more behaviour that i want to stop:
"When i press the control button & at the same time scrolls the mouse wheel, the html content is zoomed in & out."

How can i stop this.

Waiting for the suggestions Unsure | :~

   If you are trying to handle it via a right-click handler, you will need a better solution!  These are quite easy to get around (dispite many web pages that try to prevent the menu in that way).  Better to implement the host interface(s) and override the methods used in generating and showing the context menu.

   I do not think you can get around that one via script.  Have you tried using PreTranslateMessage to intercept the <CODE>WM_MOUSEWHELL</CODE> messages if the Control key is down?

   Peace!

What about typecasting...e.g. (float)5+6.5
