That calls operator=, not the copy constructor. It sounds like VC is optimizing out the copy constructor since it is never called, that would explain why you can't set breakpoints in it. (And yes, that can happen in Debug builds, I've seen it happen myself.)

Hi mike,
Thanks for your help, you were right on the money! I wrote a little TestCopy( C4DList<blob> test ) function, and this /did/ use the copy constructor and therefore VC allowed me the honour of placing breakpoints etc. I wonder if MS view the 'optimising debug build' as a bug or a feature?
now I just have to learn about operator=... 
Thanks again,
Pete

I am porting some code from C++ 1.5 to 6.0. The
combox would let me drop down other combo boxes
when one box was asked to be dropped. The new
version does not let this happen. In the message handler
ON_CDN_DROPDOWN, I would call "ShowDropDown" for
the other ComboBoxed. If I do this now, the requested
box will drop then after making the call to "ShowDropDown",
the request box will close. The new box will drop and then
immediately close, too.
Any insight would be appreciated.

This is a little off topic, but I can't think of a better group of people to ask this question.
I've recently been evaluating a debugging suite of products from Mutek. The principle product of interest is called Bug Trapper.
It attaches to one or more processes and captures all the activity (can be filtered). Then you can play it back in a session similar to live debugging, except you can look at anything as of anytime.
A couple of key features are that you can attach to any running process, it does not have to be compiled in debug mode, just need a pdb. It identifies the thread that is executing each piece of code and can be played back in time sequence or on a thread by thread basis. (Helps my multithreaded service debugging immensely).
1. Has anyone had experience with this product?
2. How did you use it? (what types of apps)
3. Was it worth it (its not clear yet what this will cost, but it aint cheap!)
4. Are there other similar/better products out there?
5. Any other comments?
As always, thanks for any help I get with this.

In WinXP many new programs have very cool checkboxes (with an hoover effect), buttons & controls...
I woluld like to know how to use these new controls... I think that some stiles should exist.... someone has any idea about that?

To get the whole XP look in your programs ( the buttons, menus, toolbars, etc. ), you need something like the Xtreme Toolkit ( www.codejock.com ), which gives you those styles as well as wizartds to create GUIs such as Outlook and Visual Studio.

Are you developing for Win XP or another operating system.
If you are using XP you can use this article:

Are you asking how to get your app to be themed when run on XP, or how to use XP-looking controls on other OSes? If the former, you need to insert a manifest into your resources so XP will draw your controls with themes. MSDN has info on doing this.

We are in trouble, can anyone help. We are trying to locate software
First Impression Visual Component V5.x or later
We have lost our CD, lost our serial number, need to support a project with the design time license which we cannot access.
We are willing to purchase this software from you if you have it.
Please check!!! thanks so much for reading.

I really doubt it. But is anyone aware of the existance of an object timeline control similar to Flash and Director ?

template
< class T >
class CVTView : public CView
{
protected: // create from serialization only
CVTView();
DECLARE_DYNCREATE(CVTView)
//Blah blah blah
private:
std::list< T* > m_TPtrList;
};
This creates a ruckus with the
IMPLEMENT_DYNCREATE
and MESSAGE_MAP macros,
not to mention that ClassWizard runs amok. So
its back to the typing wizard, expanding all the
macros and typing in the entries into the message
map. (I havent got it working yet)
Is there a more elegant way to handle this?
Are future version of MFC going to be more
sophisticated to handle cases like this?

Hi, i need to read data from an ascii file ,
but from some reason there is a conflict in my programm with the lib files and i can't use the fscanf .
is there any other way to read from the file( in Ascii )???
* i am using an MFC application.
Thankyou

If you are using MFC, take a look at CStdioFile class. You can use its member ReadString to read a line of text into CString, and than you can parse the information you want from here.

This seems to be indicative of a larger problem. fscanf() is present in msvcrtl.dll and should be available for use. However, if you don't want to use it because you're not doing standard C file I/O, you could use MFC's file read functions and sscanf() to parse the data.

In MFC you have the CStdioFile or the CFile Classes...

How can i create a modeless dialog that cant be closed. I am using it as a compulsary advertisment window and currently all my attemts at making it non-closable have failed.
I would apreciate any help u can give! 
|
|
|
|

if its modeless and purely win32 without MFC (allthough u could do the same if its MFC) try putting something like this in the WM_CLOSE handler:
WinExec("myapp.exe");
in which myapp.exe is the current application. This way it'll just restart everytime it is shut down. 
or if you really want the user not to be able to close it you could just disable their system keys, mwehe, but thats pretty gwiffy, i dont think they'd like that. U can use the following code for this:
PUINT fuiState;
SystemParametersInfo(97, TRUE, fuiState, 0);
that'll disable ctrl-alt-del and other system keys.

Write do-nothing handlers for WM_CLOSE and WM_SYSCOMMAND (SC_CLOSE).
A somewhat more annoying thing to do is to hide the dialog when the user tries to close it, create an n-second timer, then show the window (and kill the timer) when the timer fires.

if you use this method you can still close the dialog with the task manager, but if thats all you want then this is advisable yea, dont use my method it'll freak 'em out lol

the WM_CLOSE thingy didnt work. this is a modeless dialog as part of a larger app so the other technique of getting it to restart the app afterwards wont be suitable. is their a way of simply re-opening the dialog when it is closed. To start the dialog at the start of the app I am using the following in the CMainFrame::OnCreate function:
OnStartModeless()
this calls the function
void CMainFrame::OnStartModeless()
{
if(!g_pDlgModeless)
g_pDlgModeless = new CModeless(this);
}
Any ideas?

Maybe this is what you are looking for:
Assuming your dialog is myDlg:
Remove OnOK and OnCancel handlers from the dialog class.
Remove OK and Cancel buttons
Include in CMainFrame::OnCreate(), the lines (or variations of it):
myDlg.Create(IDD_MYDIALOG);
myDlg.SetWindowPos(&wndTopMost,0,0,0,0, SWP_NOMOVE | SWP_NOSIZE);
Include in CMainFrame::OnActivateApp(), the line
myDlg.ShowWindow(SW_SHOW);
You can show or hide the dialog by using SW_SHOW or SW_HIDE
as and when you need.

I can't seem to find any clear-cut example to enumerating the catalogs (databases) in my SQL server datasource using OLEDB. Does anyone have an example of this?

Use SQL DMO - There are various methods that allow you to do this
e.g. GetDatabaseByOrd
