Maybe this article[^] helps you understand the exception specifications and why they are not a good idea.

Dear All,
I just started to use MFC library together with Visual Studio 2008 to wrap around my
mathematical engine which I build as a console application.
I hope my question will be easy to answer. I have CListBox object which I fill time to time with error messages in catch block:
....
catch (std::exception& ex)
{
std::string str = ex.what();
m_List.AddString(str.c_str() );
}
....
Sometimes, error messages are longer then physical width of CListBox object and as a result truncated.
As far as I see, CListBox object does not have property in "Property list" to explicitly specify string/word wrapping. There are few properties such as "Multicolumn", "Horizontal Scroll", "Disable No Scroll" which does not help me to make it possible to view all length of error messages.
I am sure it must be easy way to do it. I hope someone will have some suggestions/comments about it issue.
Thank you in advance,
nuclph.

The easy way is to use a different control. Think about it - what would it mean to word-wrap in a list - is the wrapped text the same or different items than the first bit of the line?
For what you're doing, I'd use a rich edit control, a) so I could specify a monospaced font like courier easily, and b) it's got this[^] useful method.

Stuart is quite right - a multiline list control would be odd.
You could implement an owner draw one, and make each entry take two lines, with some sort of visual cue - but that would be hard work - and a waste if you commonly have a small amount of text for each entry.
Alternately, you could use a tooltip for your CListBox.

Indeed! I too learned truck loads from his articles. He died the night of September 3rd, 2008[^].

Wow, that was news to me. I just assumed he'd made his piles from early microsoft shares (or from bribes to answer particular reader questions) and had retired to Tahiti.
As I was largely working alone, he and Matt Pietrek were my MFC teachers.

Dear All,
I want to add the special character "&" into my label box, but when I add this, it takes as "_". I know that putting "&" before a character makes the "_" as a shortcut for Alt key.
But I want to include "&" to be displayed in my label box. Is there any way for this ?
Thanks in advance.

Try with a double &, only one will be displayed.

Have you tried using DlgDirList[^]?

Do you mean that you run a loop looking for the files, when you find one you add the path to the list, but the list only gets redrawn once your loop is done thus all your hits appear at once? If so, you have 3 options i can think of right now:
1. do the search in a different thread and send/post your hits towards the GUI thread
2. do your search with a timer
3. do your search in idle-time (when your GUI thread has no messages to process)
p.s: You could also try simply forcing your list to be redrawn in your loop with e.g. using RedrawWindow, but that would be an ugly solution.

Thanks for your reply. Yes, I have used it in loop, that's why the problem arise
|
|
|
|

Another option you can do is within your loop, when you find a file you are most likely doing
m_ListBox->AddString(xxxx)
Immediately after you do the AddString, you can add
m_ListBox->UpdateWindow() and that will cause the list box to show the new data.
Hope that helps.

Hi,
I want to launch outlook using ShellExecuteEx and I am able to launch it. But I want to pass file (mydoc.doc) as a parameter to it. So that it will open an outlook evelop and attach this file to it.
SHELLEXECUTEINFO shExecInfo;
shExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
shExecInfo.fMask = NULL;
shExecInfo.hwnd = NULL;
shExecInfo.lpVerb = NULL;
shExecInfo.lpFile = "OutLook";
shExecInfo.lpParameters = "C:\\test\\mydoc.doc";
shExecInfo.lpDirectory = NULL;
shExecInfo.nShow = SW_MAXIMIZE;
shExecInfo.hInstApp = NULL;
ShellExecuteEx(&shExecInfo);
Please let me know what wrong with this code.
Thanks
SNI

Does it work if you simply run outlook with a doc parameter from a console or using RUN in start menu? Maybe you need to specify other parameters to let Outlook know what you want it to do with that doc.

Thanks for reply. But I tried with other parameters but it is failing and giving following msg
"The command line argument is not valid. Verify the switch you are using." Is there any switch needs to be provided while specifying the file name.

Check out here[^], it says, the command line argument for attaching a file is /a <path to file>

Hi,
I would like to make it so that when the cursor is over my window it has a custom look. How can I achieve this with win32?
Thanks,
Steve

One way is to handle the WM_SETCURSOR[^] message. A different way would be to specify your own cursor handle when registering a window class.[^].

MSDN has an interesting set of "Using xxxx" series. If interested type in "Using" into the index edit box and you'll see a bunch of articles.

As per google, MTU(Maximum transmission unit) can have maximum value of 1500 bytes but I am sending more then 1500 bytes data over socket from one application to other(on differnet m/c).It is going fine. I have tried up to 3500 bytes.
Please tell that what is the maximum size of MTU and how can I find out?
Thanks in advance.

Vishal Soni
