Overwrite CWnd::OnEraseBkgnd ( for WM_ERASEBKGND message), and paint yourself the background. For example :
BOOL CTestDlg::OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetWindowRect( &rect);
ScreenToClient( rect);
CBrush brh;
brh.CreateSolidBrush( RGB( 0, 0, 255));
pDC->FillRect( rect, &brh);
brh.DeleteObject();
return TRUE;
}
this will make the background for CTestDlg blue.

Thanks everyone for your help. It's people like you that make it all seem possible to distraught newbies like me.

In Prolog, if you are not interested in some variables, you can use "_" to represent it. It means you do not care its returned values or input values. In VC++, do we have some mechanism like Prolog does?

In functions, just leave out the variable name
int func ( int n, char ch, long, void* )
{
}

Whats the easiest way to dynamically load HTML into the IWebBrowser2 control ? If I have a CString that holds html text is it possible to load it into a browser control ?
Thanks in advance
|
|
|
|
|
Yes you can . Get the document, and use IHTMLDocument2::write / writeln methods to write raw HTML data into. Or if you want to use IWebBrowser2 interface direcly , use Navigate2 method.

You can also load the page from a resource using the LoadFromResource method. (Assuming you are using CHTMLView) or by using the res protocol (res:/<MODULE_NAME>/<RESOURCE>)

One way i use is to get a pointer to an Element,
usually the BODY element, but you can do the
trick with any other elements (DIVs,SPANs,Ps,etc).
Then use the put_InnerHTML method.
One bug/feature of this trick is that you can
load an HTML file from the disk/Resourse and then
replace the body with a dynamically generated HTML string.
The document will still have the Stylesteets,scripts,METAs
defined in the section and also the attributes
defined in the body.
ex.
- - - - - - - - - - - - - - - - - -

How to get the name of the recently added file to a Particular folder?
In my project i have to find the recently added file name for particular directory.

But i have to get the file name which is recently added to the folder.
advance thanks.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Why not look at the time of last modification or time of creation, when you have to display the list of recently modified files.
But, if you have to display it realtime, watching the folder continuously seems to be the only option that you have ... If you need to display only the files that are modified during the lifetime of your application, then monitoring would be the best solution. It is not very expensive because the app is just waiting on an object...

The Win32 API functions to do this are
1. ReadDirectoryChangesW - not supported in 95/98/ME
2. FindFirstChangeNotification and
FindNextChangeNotification functions - works from 95 upwards
There is a C++ example in MSDN under the title
"Monitoring Changes in a Directory or Directory Tree". If you search this in MSDN for the exact string, ie using quotes on both sides, the example is the first result.
I am not very familiar with VB, so I do not know how you can use this info in VB. In C++, I would have a worker thread, that calls a callback function, with the changes as and when they occur.
Hope this helps

I know it's possible to wrap my entire application in an exception handler so that when our code does something it's not supposed to do, I can pop up a dialog saying, "We're crashing, here's a log of the application state."
I've even cut and pasted an example from MSDN, and I'm in the midst of trying to find that again. Can someone point me in the right direction?

Try SEH exception to hook GPFs. There are a few articles on CP about this. Also search MSDN with SEH Exception to find more.

Check in MSDN for ::SetUnhandledExceptionFilter. It works on W95 > , NT3.5 >.
|
|

Yah, as it turns out, this is what I need. After reading a bunch on SEH, I feel enlightened, but for what I need, SetUnhandledExceptionFilter() is perfect.
Thank you.

Hi,
Has anyone written or come across code to display a thumbnail image in
a CListCtrl in report or list view (ie., not icon or small icon)? Basically
I would like to develop a CListCtrl that would display a small picture alongside every entry in the list.
Thanks in advance
Wayne.

Hi All,
I have a problem which is only manifesting itself in the 'Build for Release' version of my MFC app.
I have an app which creates a worker thread, the thread returns data to the document. As soon as the worker thread terminates however all the file operations on my menus become greyed out. Has anyone seen this before , any solutions?
Many Thanks,
Louis

I am sending out data on a TCP socket and there are times when the bandwidth available between the server and the client is not sufficient to deliver data at the rate the server wants to. Is there any standard way to handle this? The data is mostly realtime and the previous data is not significant to the user, so it is ok to drop earlier packets in favour of new packets. Any suggestions ??

First, do not use TCP/IP (connection-oriented sockets) but UDP instead (datagram sockets). Then you can have a feedback TCP connection for the client to inform the server about how things are going (based on the numbering of the packets received) so that the server can adjust the speed with which it delivers the data.
There's a standard protocol that does precisely this sort of things. Its name is RTP (Real Time Protocol) and it's defined at Internet RFC 1889.

Thank you for the input...
The only problem that made me use TCP in favour of UDP was packet ordering. The messages have to be in sequence, even if I miss a few. I guess the message sequence numbers can be used for the purpose and can ignore any out of sequence messages. I am going through the RFC now.

Also do you know of any resources on the Internet or any books that looks at data compression from the point of view of a network application.
