Not sure how this relates to C++/CLI ?

You can add given window's header file ( window which is gonna be shown) to your main window unit and use a name of window's class you want to show for example:

#include "MyForm.h"<br />
.<br />
.<br />
.<br />
MyForm ^Frm = gcnew MyForm(); //define the form you want to show<br />
.<br />
.<br />
.<br />
Frm->Show(this); //show given form, from the other form

And how the causing this error looks like ?
Possible it requires explicit cast.

You probably need to ask people who know what netica.c is, and either way, you probably need to post the code that is blowing up. And, once you are asking about compiling straight C, you need to ask in the right forum.

Re: undeclared identifier

Mark Salsbery5-Mar-07 11:56

That's because NULL is defined in afx.h, an MFC header file.

You can add it to your source, header, or pre-compiled header file(s):

#if !defined(NULL)
#define NULL 0
#endif

*edit* It's defined in many places in CRT header files as well.

Please do not cross post. Also, DRM is there for a reason, don't try to violate the licenses you bought things under.

Converting DRM protected audio files to unprotected audio files is not a illegal thing. So please give some guidance to me.

Visual C++ 2005 Express Edition SP1

Hello,

After several problems with the link between a windows form and Fortran, I decided to install the Visual C++ 2005 Express Edition SP1, these problem were solved but now appear a new one. As I install Visual C++ 2005 Express Edition SP1 I have in my computer the folder

..\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.762_x-ww_6b128700 where the aplication get the dll msvcm80.dll,msvcp80.dll and msvcr80.dll

So I have a "circular" problem,

If I don't install the Visual C++ 2005 Express Edition SP1, I can't link with fortran, but If I install it and the conexion begins to work, nobody without the Visual C++ 2005 Express Edition SP1 (So without .NET 2005) can run the application, because there is no way to install these new versions of the dlls without installing the service pack.

There is any redistributable package that microsoft is going to release? or there is anyway to install only the dlls that I need?

Thanks in advance

The info: Deployment (C++)[^]
The section "Redistributing Visual C++ Files" may be particularly useful.

One possible redistributable download: Microsoft Visual C++ 2005 Redistributable Package (x86)[^]

Hope this helps!

Hello,

The problem is that if I
Build my application with the .NET 2005 with the SP1 installed, this application will not run in a computer without this SP1 installed, I have try this in a computer with VC++ 2005 redistributable package (x86), and it doesn't work, appear: Error code 14001

So I am trying to find a Redistributable package with the new versions in. Because I have add manually this dll (msvcm80.dll,msvcp80.dll and msvcr80.dll) in his new versions that are located at
..\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.762_x-ww_6b128700

But if the computer where I want to run the application has not the .NET 2005 installed (so the SP1 for sure can't be installed), this will take the dll from the folder

..\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_0de06acd which are the dll that VC++ 2005 redistributable package (x86) install inyour computer.

I am sure that something is write down in the register which point to one or another.

Regards

I'm not sure it's a good idea to rely on a certain folder to find the DLLs. This is the kind
of thing that leads to the whole "DLL Hell" thing.

I still suggest studying the deployment link I posted before. You may need to deploy the DLLs
to your own place where it is easier to access.
