You would like to create a managed C++/CLI executable using Windows Forms that can run on any computer?

No, you cannot create such an executable.

error C2015: too many characters in constant
error C2065: 'Nil' : undeclared identifier

Since you are using .NET, you should use Process::Start

That error indicates you don't know how to #include header files for C++ development. The fact that you don't know that indicates that you need to step back to student mode and learn some prerequisite programming topics before you try to write working windows applications.

first of all the type of formas application you need is.... CLR Windows Forms Aplication

create a process outside the namespace.. and use these headers..
#include string
#include windows.h
#include process.h
using namespace std;
unsigned __stdcall execplz(void *params);
string cl;

somewhere in your program you need to place the following line to execute the command;

<br />
unsigned sID; (HANDLE)_beginthreadex( NULL, 0, execplz, NULL, 0, &sID);<br />

and keep in mind the command line string is std::string cl;
which i have set as global string at top so you can use anywhere..
the process below will create a process invisibly to yours ok.. so
to change that you need to remove... si.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

<br />
unsigned __stdcall execplz(void *params){<br />
string fnn;<br />
int nLen = cl.length();<br />
bl=cl; std::string::size_type idx; idx=bl.rfind("\\");<br />
bl=bl.substr(idx, string::npos);<br />
cl=cl.substr(0, idx-1);<br />
int nLeng = bl.length();<br />
<br />
LPWSTR szCmdLine = new WCHAR[nLen+1];<br />
MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,cl.c_str(),nLen,szCmdLine,nLen);<br />
szCmdLine[nLen] = '\0';<br />
<br />
LPWSTR fnonly = new WCHAR[nLeng+1];<br />
MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,bl.c_str(),nLeng,fnonly,nLeng);<br />
fnonly[nLeng]='\0';<br />
<br />
    STARTUPINFO si;<br />
    PROCESS_INFORMATION pi;<br />
   GetStartupInfo(&si);<br />
   si.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;<br />
   si.wShowWindow = SW_HIDE;<br />
    ZeroMemory( &si, sizeof(si) );<br />
    si.cb = sizeof(si);<br />
    ZeroMemory( &pi, sizeof(pi) );<br />
<br />
	if( !CreateProcess( szCmdLine, fnonly, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi) ) { printf( "CreateProcess failed (%d).\n", GetLastError() ); }<br />
return 0;<br />
}<br />

ok so the reason why i have this a separate process.. is because its using threads..
you can use this at anytime even when soemthing else is going on..multiple times at once
if wished.. good for creating webservers and such...

Knowing that i introduced in Begining:

using namespace System::Diagnostics;<br />
using namespace System::Threading;

But before this work, and Form1.h opens normally, when I click on Form1.h the interface of my project which cames but there are error.

Looks like you are running as a low-privileged user. Try running as administrator (or a non-admin higher-privileged user).

I am talking about the Windows logon user here. You'd have to change user permissions from the control panel. The exact applet to do that would depend on your OS.

Since this is the the C++/CLI forum and not the Visual C++ forum, I will suggest the following book on Managed C++:

C++/CLI, The Visual C++ Language for .NET by Gorden Hogenson, Apress, ISBN-13: 978-1-59059-705-7 and ISBN-10: 1-59059-705-2

Like the message said, this forum is for C++/CLI and mixed mode programming only. So, the first step is to learn to read and follow directions.

The next step is to buy a good beginner book and work through it. VC++ 2005 Express Edition is free to download, so no problem there. Once you work through a good book, you will know enough to take on some simple projects and ask questions as you continue to learn from there.

You can't "execute text". Perhaps you could try to explain again.

It is pretty obvious what he wants - though he didn't express it well. He wants a word document to be opened on a button click.

Yes, and that surprised me.

Interestingly enough, I am not a linguist either. His first post said :

"I want to open a word document with Windows Forms applications, from a boutton; when i click on this boutton a document text which is going to execute, thank you. "

To me, it was pretty easy to understand what he meant. Though I guess that doesn't necessarily mean everyone else must understand it too.

I was just surprised that you didn't understand him, that's all.
