I see. I was confused because the first post was by Mao. The second was anonymous and I wasn't sure about Mao posting anonymously.

I'm confused
The message "Thanks for your help  "
doesn't represent a bad think...
It was simply my ironic death, the
death of the lost programmer...
anonymous why i don't know...

Has anyone been able to use a System::Timers::Timer object in their Managed C++ code?
I can't get it to be recognized by the compiler, yet the help documentation indicates it is a .NET class and there is C++ support for the types.
Can anyone point me to a header file to include or some example code somewhere.
Thanks
Jim

For the following class header member declaration
System::Timers::Timer* timer ;
Yeilds the following error
"error C2039: 'Timers' is not a member of 'System'"

You need #using <system.dll>

No that is not it. I tried that first. If you put in a
#using System::Timers ;
statement you get an "error C006 '#using' : expected a filename, found 'identifier'
Thanks though.

You cannot do that. System::Timers is a namespace name. You need to use using namespace System::Timers;

If Rama's understanding of your problem is correct you have a compiler error. If so, put this on top as he has suggested :-
#using <system.dll>

I didn't know that. I think what you have done would translate to the same thing in C#. Wouldn't it? But why is that important.

Yes you can. It's called a vector of vectors. Someone told me you can use STL in MC++ if you don't care about interop.

Well, I dunno to what degree they can interexist. Obviously you'd have no interop, but I see no point in interop unless you have a language that is actually vastly different to C++ to interop with.
And either way I thought it was worth pointing out that jagged arrays are not a new idea.

I know that. That's why I wonder why they left it out of the managed extensions. But I have got info that it will be included in the next release of the VC++ compiler

HI
I have just upgraded my application written in VC++ 6.0 to VC++.net. i am receiving errors in message map. the description of error is
error C2440: 'static_cast' : cannot convert from 'void (__thiscall CProjectView::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'
i am quite frustrated. Is anybody out there who understands what is the possible cause of this error.

I would like to open more than one Form at once and can't seem to do it. I have a base form and want to pop up a custom message box form on top of it when needed. Anyone have any ideas?
Thanks in advance,

I guess you mean modeless forms. You can use Show() for that.

If you mean, you want a modal form you need to use ShowDialog() instead of Show()
Or you can use the MessageBox class

Hi! The .NET collection classes have me pissed off. Being a C++ kinda guy, I love linked lists and I find the dynamic arrays to be really inane. So, I'm creating my own linked list class. I'm having some trouble with the enumerator:
An IEnumerator interface to an IEnumerable object is valid so long as IEnumerable wasn't modified after IEnumerator was created. How do I let my IEnumerator class know that my IEnumerable was modified?
I don't want to use a DateTime/TimeSpan class. I was thinking of incrementing an integer everytime the list is modified and making that the hash code. the IEnumerator could store the hashcode when it was created and compare it to the current hashcode. However, with extensive use, this procedure may not work.
Any suggestions?

Refer to Nish's excellent article on implementing collections in MC++. He uses one possible solution (flag to say if it is modified).
