"RE: to use this class you need to include the System.Windows.Forms assembly and add the namespace on top of your .h"
you need to add the namespace like:
using namespace System::Windows::Forms;

Hopefully you are talking about C++/CLI and not pure C++! You cannot use managed classes in a pure C++ application.

C++/CLI should be treated as a separate language.
C++ is still C++. No obscure characters have been added.
Are you sure C++/CLI is what you want to use? There's also
a way to use the open file common dialog from native C++.

Hello Mark,
RE: Are you sure C++/CLI is what you want to use? There's also

No, I am not sure at all I want to mess with this. I activated Help from my Visual Studio to find out how to open a dialog for opening a file. I wound up here, but I am not at all sure where I want to be.
Thanks for your time

Hi,
I am writing a pure C++ programe. I need to use strcpy_s() in my programe. As of now my compiler is not supporting strcpy_s(), what should I need to do if i wan u to use strcpy_s(). Do i need to download any library of standard (ISO/IEC TR 24731 ), is it free?
I don know how to go about it, so please let me know how to get more info about it?

You cannot use strcpy_s in versions of C++ before VS 2005. Download Visual Studio Express for C++ if you want to use it for free. However, you loose MFC and ATL, for example. Please, direct your "native" C++ questions to the C++/MFC forum.

Hi,
I program with C++/CLI and Visual Studio 2005 currently.
I would like to improve my Application with graphical effects like highlighting selected bitmaps or
other Objects. I would also like to use shadows for Lines, Rects etc. But i don´t know how to.
Following would spring to mind
1) I try to use the simple Functions of System::Graphics. But I doubt i would manage to get good results. Are there any Code-Samples for higlighting and shadows?
2) I use the new WPF. But neither C++/CLI nor Visual Studio 05 seem to support it well...
3) I use DX or OpenGL. But i have no experience with it so far.
4) I use some other Library that might be around. Do you know any? 
So I´d like to ask: What do you think would be the best solution?
I appreciate any help,
Best wishes

Hi All,
I could not find the actual difference between strcat_s() and strcat(). Is it possible to use this in MSVC++ 6.0, boz when I tried to strcat_s() I got the error "error C2065: 'strncpy_s' : undeclared identifier" (i hv tried using both #include <string.h> and #include <string>).
And other doubt is whether this will work both in UNIX and windows, as I am developing a C++ application which should be platform independent.
If i want to use strcat_s() in MSVC++ 6.0 which include file i need to use.
Thanks

I don't think so. The "safe" string functions came with the CRT starting
with VC 2005.
And please post non-C++/CLI questions on the Visual C++/MFC board.

Hi
Is there any tool that could analyze managed C++ code to identify (i am using Visual Studion 2003).
1). memory leaks
2). index out of bounds
3). memory overruns
I have seen Devpartner and Rational PurifyPlus but they do not work with managed C++.
Thanks in advance.

Check out the ANTS Profiler[^] from Red Gate. I haven't used the memory profiler portion myself, but it's awesome for quickly finding speed bottlenecks in your code. Not very cheap, but well worth it IMHO.

I have tried using Ants Profiler but it works on ".Net 2.0 Framework", I want something for ".Net 1.1"
These are the cases that I want the profiler to detect.
---------------------------------------------------------
Case 1
Reading values at an index that is out or range (using array).
Case 2
Writing values at an index that is out or range (using array).
Case 3
Reading values at an index that is out or range (using vector).
Case 4
Writing values at an index that is out or range (using vector).
Case 5
Memory leak.
Case 6
Memory overrun using array.
Case 7
Memory overrun using malloc
Case 8
Access memory that has been deleted

We have a desktop utility that has enjoyed some success in the market place and a vendor who’s mission is to tie things together has almost reverse engineered our internal API that we provide to a VB like scripting engine.
We Authenticode sign all our modules and are getting ready to introduce new functionality that uses .NET code in DLL’s.
Any suggestions on the best low impact way to make sure that we do not have unauthorized third parties attempting to use our functionality?

You could look into code obfuscators. There are several good ones out there.

I have been reading all day long on how to open external programs, i've been told several times to do this
#include ^stdlib.h^ or #include ^windows.h^
system("...");
when I try to do the #include, it fails on build, if I try the system only, it fails on build.
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {system("C:\\Program Files\\America's Army\\System\\Armyops.exe");}
That is what i am trying to do.
I've tried searching on here but I can't come up with the right word sets to to actually find it.
Note: ^ is the great then and less then signs that don't show up in text.

Use the Win32 ShellExecute() (documentation here) function to do this.
And for < and > use < and > or select Ignore HTML tags in this message in the formatting section at the bottom.
Hope this helps,

to include header files you need to surround your header name with double quotes or w/ a greater than and less than sign
ie:
#include "stdafx.h"
or
#include < stdafx.h >

Hello!
When I have a managed pointer to a local object t that goes out of scope,
the destructor of t is called. Does pt still point to valid memory (and I
can mark t as invalid), or is there any other way to find out if the object
pointed to by pt was destroyed?
Test^ pt;
{
Test t;
pt = %t;
}
pt->...
Thank you!
Alex

pt is still valid in your code.
There's no "pointers" here - these are managed references.
You have created a new reference to t by assigning a tracking
reference of t to pt. As long as pt stays in scope it is a
valid Test reference.
You can assign nullptr to references...
Test^ pt;
{
Test t;
pt = %t;
}
pt = nullptr;
if (nullptr != pt)
{
pt->...
}
*edit* I played around with this and with stack based semantics<br />
the destructor is still called as you stated. This behavior makes code <br />
like your example dangerous.<br />
<br />
I'd prefer using all reference semantics if I was going to obtain additional<br />
references, something like
Test^ pt;
{
Test ^t = gcnew Test();
pt = t;
}
delete pt;
pt = nullptr;
That seems clearer to me *shrug*

Thank you.
I see that the local (ref) object is also on the managed heap
- the only difference is that the destructor is called.
In my case, I need the local object because it is a lock
(which has to be destroyed when leaving scope).
