Process::Start problem

[Atli]

Hi o/

I decided this morning to teach myself C++ \o/... 6 hours later Im just about ready to throw in the towel :)

Anyways I have a minor annoyance you good ppl might be able to help me with.

I created a simple code to open a .exe file in C# wich work fine (all hail C# :P)

System.Diagnostics.Process proc;
proc = System.Diagnostics.Process.Start(@"C:\dotnetfx.exe");
proc.WaitForExit();

MessageBox.Show("omg");

Now this is fairly simple. Runs the dotnet.exe and when that closes, it echo's "omg"

And now for the problem.
I tried to do the same thing in C++

System::Diagnostics::Process proc;
proc.Start("C:\\dotnetfx.exe");
proc.WaitForExit();

MessageBox::Show("omgOMG");

No matter what I do, the proc.. after I call the Start(...) function, gives me a Exception saying there is no proccess attached to it.

I tried

proc = System::Diagnostics::Process::Start("C:\\dotnetfx.exe")

but it gives me a build error.

Anybody know what to do?

Are you running this in windows? If so, you can use

system("C:\\dotnetfx.exe");
cout << "omg";
return 0;

to accomplish the same.

I tried your code. It gives me a error:

error C3861: 'system': identifier not found

This is a part of a Windows application
(Windows::Forms ::Form) thingie

The code I posted is inside of a event triggered function, triggered when the form is displayed (this.Shown)

The basic Idea is that I want this program to open up, install .Net framework and then execute my acctuall program, wich is wirtten in C#

this is the entire code..

public ref class Form1 : public System::Windows::Forms::Form
{
  public:
    Form1(void)
    {
      InitializeComponent();

      SetupStart::Form1::Shown::add(gcnew EventHandler(this, &SetupStart::Form1::Execute));
    }

  void Execute(Object^ sender, EventArgs^ eArgs)
  {
    // Here Im trying to install .Net
    System::Diagnostics::Proccess proc1;
    proc1.Start("C:\\dotnetfx.exe");
    proc1.WaitForExit();
  
    // This is where my C# app should start
    System::Diagnostics::Proccess proc2;
    proc2.Start("C:\\myapp.exe");
    Application::Exit();
  }
}

I'm using C++ Express 2005 to create this.
