I need to contain a web folder view (like the one in the Explorer) in an application for a selected file.
Does anyone know how to implement it in an easy way?
Can I use a shell view for this?
Thanks!

Hi,
Is it possible to retreive the type of a variable ?
I want to pass this type to a template like in :
Vect2d < int > vect, but I want to replace "int" by an
argument containing the type.
I have tried with a string, but whitout success.
Anybody knows if I can do that ?
Thanks,
Claude

To find out the type of a variable at runtime use a C++ feature called RTTI (runtime type information).
It is explained pretty well in the MSDN.

I'm not sure I understand what you mean.
Templates are compile-time. That means the type must be known when the program is compiled. Can you give an example of what you are trying to do?

Hi,
I having problems vith VS. Everytime I use the ClassView for adding a new function the class disappears from classview - you know rightclick on the class and choose 'Add Member Function'.
When I delete the project's .NCB file everything is back, until the next time I decide to add a function.
Has anybody experienced the same?

Hey Christian,
I used to experience a bug similar to that in the ClassView, but was resolved when I installed SP4. What version of VC on which OS are you using?

Hi Paul.
Thanks for your reply.
I'm running Win2K with VS6. I too tried installing SP4, when I got the problem, but unfortunately it did'nt work.
I uninstalled everything and installed VS from scratch. It took half a day but now everything works fine (until next time something goes haywire)
There are still the same problem if I delete a member function from the classview - but I can live with that.
I *really* look forward to the next release!

ClassView can be very sensitive at times to things like Macros, typedefs, and templates. I've seen Macros that make member variables show up as globals in ClassView, and all kinds of weirdness. Typically, you start to lose visibility in ClassView when CV parses something wrong. My suggestion would be create a copy of the project, then start removing files until the problem goes away. Then figure out what's weird in that file.

Thanks for your reply,
Actually I just uninstalled VS and installed it from scratch.
Your idea is good, and I will try that the next time it hapen ( I'm sure it will  )

What methods do you use for localization?
I've been struggling with this for quite some time. The problem is that it's very error prone to keep multiple resources for each language. Whenever you change one, you need to change them all, and when doing complex updates you can often forget. This then requires extensive testing in all languages.
What are your localization strategies?

I use dynamically sized resources and read the texts in at runtime. I found this to be stable verus changes in display preferences (e.g. bigger fonts). I one app the user can change languages at runtime. All buttons/dialogs/... resize and redisplay. This means automatic layout, so you can't be all that fancy as if you did pixelalignment yourself.
I got the basic idea from KDE.

I am looking at a bug in a project I working on, which uses lots of dialogs attached to a tab control. All dialog classes a derived from one of two class in a framework for the the system. In just one the message map is not trapping the set focus message for a reason that is not obvious. It is very strange because out of some 200 tabs only one is giving trouble.
I thing I have checked all the obvious things - any other sugestions would be welcome.
Happy programming!!

hi,
I need help with this:
I made a dialog box, and in this dialog box there is a Rich edit field. Now, when I press 'enter' the dialog box closes. I've tried everything I could think of to stop it from doing that.I want it to just add a return in the rich edit field.
Can somebody help me with this?
|

The <return> key is mapped to the OK button, and the <escape> key to the Cancel. You may be able to change this by making your rich edit the default control, but I suspect you will need to over-ride OnOK, and in it check if the return key is down ( GetKeyState(VK_RETURN) from memory ) and, if so, return - that is, don't call CDialog::OnOK();.

Set the "want return" style for the edit control, then it'll do what you want.

I agree with Michael and Erik, you need to find a better approach. You should consider using a grid control, or the listview control. It will make your life quite a bit easier.

If you're using that many checkboxes, there's something else wrong with your app. It won't run well under Windows 9x, since Win9x has much more limited resource pools for window handles (of which a control has).
Re-think your design. There has to be a better way to do this. If I were one of your users, I'd shoot myself (or you) if I had to use such an interface.

Egads. Well, if you really need that many checkboxes, use a CCheckListBox instead. Or a CListCtrl with the checkboxes style.

Hi All,
I have a small problem achieving something with a CRichEditCtrl (MFC). Basically the problem is that i would like to determine the height (in pixels) of the text contained within the control.
For example, setting the height of the control to this value would result in the text fitting perfectly within the control. (i am only interested in the vertical direction)
The control can contain varying sizes and fonts of text within it, as well as multiple lines.
I hope one of you has a clue on how to accomplish this.
Any suggestions would be most appreciated.

When I write the server/client application with Winsock
using "CreateIoCompletionPort", in loop of "GetQueuedCompletionStatus" to check the sock communication, if clientside disconnect by call "closesock",
how to check or response in server side "GetQueuedCompletionStatus" code? If client call
"shutdown", how to check it in server "GetQueuedCompletionStatus"?
Can somebody give help and show some sample code?
Thanks a lots

I can't remeber but I'm sure i read somewhere that if the byt4es transferred were zero the client has called close scoket - in our code we have the following
BOOL bRet = GetQueuedCompletionStatus(_hIOCompletionPort, &dwBytesTransfered, &dwCompletionKey, &pOverlapped, INFINITE);
// If an error occured ensure that we flag the socket as closed so that the cleansweep thread destroys any
// system resources associated with the thread; If we receive zero bytes in length the socket is being closed
// on the client side - as we don't care for data loss (caused by a shutdown?)
if( !bRet || !pOverlapped || dwBytesTransfered == 0 ) {
pSocketInfo->State = SocketInfo::SocketState::Closed;
continue;
}

Having looked on MSDN at:
http://support.microsoft.com/support/kb/articles/Q105/6/75.asp
and
http://support.microsoft.com/support/kb/articles/Q250/5/63.ASP
I am still no clearer as to how I can disable the first-chance exception notifications in the Output Window of VC6. The articles above talk about the 'Encompass Monitor' service, but this is not running on my NT4 SP6 machine and neither encmonitor.exe or monitor.exe are present on my hard drive.
I noticed that neither of these articles specify NT4 in their 'information is this article applies to...' header.
I use a third-party ActiveX control that causes first-chance exceptions like no tomorrow and I would dearly like to prevent these from appearing in my output window.
Can someone please assist as it's driving me up the wall.
Thankyou
