You can pass a pointer as Rick suggested. I'll add this...

make sure the object pointed to stays in scope Smile | :)

// e.g.
double mydouble = 4.2;
_beginthread(&mythreadproc, 0, &mydouble); <code><-- BAD!!! mydouble may go out of scope before spawned thread uses it!</code>
return;

I used this MDI Article[^] or MSDN MDI Article[^] but it still gives me errors, I've searched for about a week with thousands of different combination's to get the information i am looking for, can someone teach me or show me an article on how to create MDIParents and Child's and open the child windows when clicking on a button or a menu.

Error	1	error C3699: '*' : cannot use this indirection on type 'MDITest1::Form2'	c:\documents and settings\nicholas king\my documents\visual studio 2008\projects\mdi test1\mdi test1\Form1.h	164<br />

Looks like that code was written for Managed Extensions for C++
(Visual Studio 2002/2003 .NET).

There is a compiler option to support the old syntax but upgrading
the code to the new syntax is the best long-term option IMO.

Just to make sure - is a .NET forms app really what you want or do you
want a native MDI app? If .NET forms is what you're after, you're posting
on the wrong board. Smile | :)

Alright, well I am using 2008 and I can't find anything on the new syntax even on MSDN.

Sorry about posting on the wrong board, I usually posted my questions here.

I want native, but doesn't matter to me.

list ".remove()" issue

Hi everyone.
I'm having some problems removing objects from a list.
Here's the code.

cout<<"Name of the band you want to delete: ";
                  fflush(stdin); getline(cin,nameband);
		  band = myManager.select_band_name(nameband);
		  if(band!=0)
		  {
		  (...)
                  myManager.remove_band(*band);
                 (...)

The remove function is this:

void Manager::remove_band(const Band & bd)
{
	available_bands_list.remove(bd);
}

There are no debug or run-time erros... did I miss something?
Thank you.

Is the "band" you're trying to remove really in the list?

I mean, it looks like you store Band references in the list and the reference you're trying to remove may refer to another object which is not in the list.

yes.. it worked. I mean, there where no building errors or run-time errors after I made the changes you told me to. The thing is I run the remove function but the object remains there.

Have you tried the example code[^] and seen that it works?

Once you see that works correctly, you should then suspect your operator implementation is faulty. You can verify this by debugging.

Hey mike.. you were right, it was the operator. It was implemented badly. So now it works perfectly! Thanks to everyone. Cheers

Hi,

I have tried allowing VS2005 to convert several existing 'VC++6 compilable' projects and with each the results are the same. Tons of ATL related compile errors. None of the projects that I am trying to convert even use ATL! I am assuming this is some sort of compiler/preprocessor setting? The errors occur in:

atlalloc.h
atlconv.h
atldebugapi.h
atltrace.h

I have included below, the first part of the Output display from the compile.

Any help, ideas or a pointer to an answer would be greatly appreciated!

Thanks,
Doug
