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.

ClistCtrl in LIST or REPORT view with thumbnails?

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. Confused | :confused:

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 Confused | :confused:

, any solutions?

Many Thanks,

sending data on a TCP socket

User 988524-Jan-02 4:26

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.

Hi!
I am displaying a Dialog Box and I have removed the System Menu from the Properties of the Dialog BOx.

Removing the system menu shouldn't remove the caption. Have a look through your options in the dialog editor, and see if you've changed the dialog from popup to child, or something. It's a drop box on the left of one of the tabs.

To change the icon, just change the icon for the program, it's a resource. To do more you need to handle WM_NCPAINT.

resizeable sign

24-Jan-02 3:56

how do you draw "triangle with lines at right-bottom" of resizeable dialog (without status-bar)?
resizeability is not enought
i afraid to draw it own way to keep compatibility with possible skins or new system versions

Try looking for resizable dialog classes on codeproject or codeguru and try comparing them to resizable 'skinned' projects. I created a skinnable dialog box that resizes so it is possible.

.NET or not .NET? MFC is the question......

It's part of a status bar. See CStatusBar in MSDN and also try building an MFC Appwizard SDI application. It has a status bar with a Gripper (as it's called) by default.

Sorry to dissapoint you all with my lack of a witty or poignant signature.

If you need the gripper without a status bar, you can create it; it's a style of the Scrollbar control. Never tried to use it this way myself though, or even seen it used, so can't tell you how it works.

If you just want to draw it, you can use DrawFrameControl() to do so:

<br />
::DrawFrameControl(hDC, &rect, DFC_SCROLL, DFCS_SCROLLSIZEGRIP);<br />

...You can use ::GetSystemMetrics(SM_CXVSCROLL); and ::GetSystemMetrics(SM_CYHSCROLL); to get the correct width and height.

variable loading using XML

Jon Newman24-Jan-02 3:55

24-Jan-02 3:55

I am developing an app that will read an XML file from a standard web server and use its contents as variables in a dialog based app. I will be using it to read member profiles. There will be a separate XML document for each member using the following XML tags.

<name>Joe Bloggs</location>
<age>24</age>
<location>England</location>

and these will be displayed in the dialog as:

Name: Joe Bloggs
Age: 24
Location: England

The field names are labels in the dialog and the variables are taken from the XML document.
The idea of this is to be able to update user profiles myself without having to re-distribute the app or use a HTML web page control.

Andy ideas would be gladly appreciated.

I'm sort of playing around with the same stuff right now. You need to use a parser and that sort of means MS's parser. You might take a look at the following site:

http://www.earthweb.com/article/0,,10455_629271,00.html

It contains about as much useful information as I've found so far. As usual the MSDN documentation for the C++ side is very sparse.

Let me know what you find out.

Here's another link:

Also, after looking a little more closely at MSDN it is a little more thorough than I thought at first. The "XML Dom Methods" section under the XML section (Platform SDK Documentation/Data Services/XML...) should be enough to get you started. I'm up and rolling now.

SetMenuInfo?

Hello

,
Did anyone use the SetMenuInfo API?
I want to use it in a MFC project but all I get is:
'SetMenuInfo' : undeclared identifier message
So can you please tell me what should I include or define or what ...
Thanks!

Best regards,
X3m

Note: MFC already provide ModifyMenu function that can do what you want.
In case you still want to do it Yourself, here's an example:

BOOL ChangeMenuText(LPTSTR szText, UINT nID, CMenu* pMenu)
{
	MENUITEMINFO mii;
	memset(&mii, 0, sizeof(MENUITEMINFO));
	mii.cbSize = sizeof(MENUITEMINFO);
	mii.fMask = MIIM_STATE|MIIM_TYPE;
	mii.wID = nID;
	mii.fType = MFT_STRING;
	mii.dwTypeData = (LPTSTR)szText;
	mii.cch   = _tcslen(szText);

	return ::SetMenuItemInfo(pMenu->GetSafeHmenu(), nID, FALSE, &mii);
}
