In Western European fonts, the widest character is usually capital letter M (that's why typesetters refer to em-height and em-width). Most fonts will contain a character call em_space, which is a space that is exactly as wide as the widest character in the font.

That's why I said 'usually' Wink | ;-)

em-space (or em_dash) should still be valid, though...

Here you go[^]
There are algorithms and the encryption levels related to each one that you might use.

You need to google first, if you have "It's urgent please" mentioned in your question.

How to change focus from TreeView to ListView using tab in MFC?

Hello, I am currently working on an MFC project. The project have a treeview and listview similar to the layout of windows registry editor. I was just wondering if any of you guys know how to change the focus wherein if the user click one item in the treeview and then presses the tab key the focus would be changed to the corresponding item in the listview? Please help.

Try it

/*virtual*/ BOOL CLeft(Right)View::PreTranslateMessage(MSG* pMsg) 
{
  if (WM_KEYDOWN == pMsg->message) {
    if (VK_TAB == pMsg->wParam) {
      CWnd* pcWnd = YourFunctionToGetRight(Left)View();
      if (pcWnd) {
        pcWnd->SetFocus(); // :)
      }
      return TRUE;
    }
  }
  return CBaseOfLeft(Right)View::PreTranslateMessage(MSG* pMsg);
}

virtual void BeHappy() = 0;

I have tried the code above but it slows down the application to the point it no longer populates the treeview, is there any other alternative?

Hi,

I have a dos console process communicating with a MFC Win32 program/process

I created a Cevent object passed the synchronization object to Dos console process created Process Table entry (DuplicateHandle)

on the MFC WIN32 end I have a Cdiloag residing in a Cwinthread UI flavor

My question is can the WIndow sdk api call SetEvent (to signal the shared Kernel object event) genarate a message to

the MFC Cdialog thread

thankx

If i understand your question, you should be able to intercept the event and generate the message yourself.

yes it should work. You use the HANDLE value of it not the object!!!

You can also use ::PostMessage(HWND,MSG,0,0) API. It works fine because it fits best in the Windows-GUI.

As i understood, you have two applications
1. Console Application
2. MFC GUI Application( GUI thread derived )

Now you create a CEvent object in console application and duplicate the handle of the event object in MFC GUI.

So that means, you are looking to get the event change in both process, isn't it?

Now you have a doubt that if you call a SetEvent from Console application then whether it will generate a message to MFC thread.
As far as i understood, if u have the same concern then

It is yes, it will signal the wait inside the GUI application. But remember one thing this event is send to all the applications which have the same named event.

It was unamed I used DuplicateHandle to create an Entry in console process table

I think the best I can do is signal the event

and then send a message or post to the Cwintnhread UI/CDialog object

thankx

Fences is a very usefull desktop icon manager.With it,you can create many groups of icons on your desktop so that you can find your icons more easily.I am curious to know how to develop a desktop icon manager like "fences".
The problem is how to create the transparent area that I can drag my icons in.This area seems like a dialog,but I don't know what exactly it is.I have used spy++ to tell what the hell it is,however,I failed,it turns out to be nothing.I don't even know how to start it.
Thank you! Smile | :)
