sure, if the author of the control wants to store and report all the font usage for that control, you'll be able to get it. but in general, there's no way to know which fonts a window has used.
|
|
|
|

As Chris said, it is not guaranteed to get what you want.
A window or control has an associated device context and a device context has an associated font.
However, when a window draws text it can change this.
You can get the currently associated font using the GetTextMetrics[^] function.
But this may not be the expected result.

You could try experimenting with API hooking, however, this might prove to be quite a challange, if possible at all, and it might or might not produce the required result.
You could try hooking the GetDC[^], GetWindowDC[^], BeginPaint[^]... (and probably their counterparts also, ReleaseDC, EndPaint, ...) and the kinds, also DrawText[^], DrawTextEx[^], TextOut[^], ..., keep track of the connection between the Device Contexts and window handles, querying the font information at the right places (e.g. like when DrawText is called).
Check out this article: API hooking revealed[^] for more info on API hooking. The hooking part itself is somewhat easier if you try to hook things in your own process, no need to 'Inject' a DLL, you can simply load it.
Btw, why do you need that information? Just curious here...

In general case, except the discovering of the font color  :
void TryGetFontInfo(CWnd* pcWnd)
{
if (pcWnd->GetSafeHwnd()) {
CFont* pcFont(pcWnd->GetFont());
if (pcFont->GetSafeHandle()) {
LOGFONT sLF = {0};
pcFont->GetLogFont(&sLF);
}
}
}

Try adding WS_TOPMOST[^] to the extended style of your dialog.

This is expected behavior, if you click outside a modeless dialog, the focus goes to whatever you selected, that's what modeless dialogs do. If you don't want to lose focus, use a modal dialog. You can use the top most approach that was suggested, but your dialog is going to always be in the way of whatever it is you're selecting behind it so this should only be done if your dialog is small.

Simply set the System Modal property of the dialog to True and it will get the top most style.

if you put system modal property to true,it will lose it basic functionality as modeless dialog box

So which C++ documentation tools have you used? I know about Doxygen, of course. I'm just wondering if there's anything better/easier to use. It doesn't have to be free.

I use the MSDN recommended XML Documentation[^] these days, but I only code for my own amusement.

I also use Doxygen, but I've also set up my UML tool, Enterprise Architect, to automatically convert the comments I add in the diagrams to the right format for Doxygen, and I set up my VisualAssist makros to also create function header documentation in the right format with all parameters and the return value listed. So all I have to do is fill in the actual meaning, no matter whether the code comes straight from UML, or has been added within VS.
The funny thing is, noone ever looks at the docs I created with Doxygen, people (including myself) are happy enough just with the oddly formatted comments

What are the differences between overlapped window and popup window. Does the overlap mean that window can overlap each other? and popup window can't?

I think the Microsoft documentation could be a bit clearer. In reality the basics of both types are the same but the overlapped window has a title bar and a border. you can see for yourself by creating a very basic Win32 program (as described in Win32 Window Minimal[^]) and experimenting with the different window styles.

Have you tried it, and if so, what were your results? Alternatively you can find a lot of suggestions here[^].

You'll need to handle the WM_KICKIDLE message in order to work with ON_UPDATE_COMMAND_UI in your dialogs.
Here[^] is a very detailed article on this topic.

Hello !
I use WSAAsyncSelect to do a small ChatSystem in the WLAN Server.
(the max client may be has 100-200 online,and the ordinary time is 30-50 online at the same time.)
like this:
SOCKET sock = (SOCKET) wParam;
if(WSAGETSELECTERROR(lParam)){
DeleteClient(sock);
return;
}
switch(WSAGETSELECTEVENT(lParam)){
case FD_ACCEPT:
sClient = accept(wParam, (struct sockaddr *)&client, &iAddrSize);
WSAAsyncSelect(sClient, hwnd, WM_SOCKET, FD_READ | FD_CLOSE);
break;
case FD_READ:
ReadData(sock);
break;
case FD_CLOSE:
DeleteClient(sock);
break;
default:
break;
}
at last ,when add/del client, it will refresh onlines info to the Server's list control. May be it doesn't receive the FD_CLOSE message.
but usually ,it has some few days ago results. I run in the Lan and use other Lan computer to test it, but can't found this problem.
How about this ?
Thanks for you reply !

hello i hope this will work.
don't use WSAAsyncSelect() probably your window might be missing some messages posted by
mfc socket framework (This will happen)
use WSAEventSelect() by creating one more thread. send notification messages to your main window by using SendMessage() function. it will work perfectly.
Possibly one more reason is
Socket abort operation notification will take at most 2 msi cylcles ( 1 msi is 2 minutes).
this is tcp ip implementation
bye

If client side closes normally, Close-event will be sent to server.
But, if internet or network connect-line breaks or some odd things happen, Close-event will not be sent to server.
in your test, you closed client socket normally, so you can't find problem.
try to plug out connect cable to see what happens.
