C# to C++

My test for compilablity was on a test machine with Beta 2 (got to update that...).

Anyway - we've fixed one minor bug ("DateTime::Now.ToString") and implemented a work-around to the difficulty that the VC++ compiler has in recognizing "DialogResult::OK" (for some reason VC++ needs to have it fully qualified, even though all other .NET compilers recognize it).

However, we deliberately leave the parameterized Dispose method - we convert parameterless Dispose methods, but you'll have to decide how you want your parameterized Dispose method to look in C++. Note that the Beta 2 compiler allows Dispose(Boolean) - that's why it compiled for me. Once you change this, the code will compile.

Here's the updated code:

Ok thanks, I got that last error fixed but how come when I debug and run it, when I click the close button (which is button3 by the way) it closes form1 but I have it set up so that when I click button1 it should close form1 then not by clicking button3. Look at the code above, it says button1's click event not button3's should close form1 and open form2. I don't get that.

I'm doing it in Visual C++ 2005 Express Edition. What Version exactly are you doing it in
Deadman
Try using...

Application::Run(gcnew frmSigner());

instead of...

Application::Run(gcnew Form1());
Santosh

Thanks it worked, but I got one last error:

------ Build started: Project: Map_Maker_Worker, Configuration: Debug Win32 ------

Compiling...

Map_Maker_Worker.cpp

.\Map_Maker_Worker.cpp(16) : error C2061: syntax error : identifier 'Form1'

Build log was saved at "file://c:\Documents and Settings\Aaron Chapman\My Documents\Visual Studio 2005\Projects\Map_Maker_Worker\Map_Maker_Worker\Debug\BuildLog.htm"

Map_Maker_Worker - 1 error(s), 0 warning(s)

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

and when I follow it, it takes me to the actual project code rather than the form1 code:

// Map_Maker_Worker.cpp : main project file.

#include "stdafx.h"

#include "Form1.h"

using namespace Map_Maker_Worker;

[STAThreadAttribute]

int main(array<System::String ^> ^args)

{

// Enabling Windows XP visual effects before any controls are created

Application::EnableVisualStyles();

Application::SetCompatibleTextRenderingDefault(false);

// Create the main window and run it

Application::Run(gcnew Form1());

return 0;

}

In the final version of Visual C++, Dispose methods don't appear in windows forms.

Change the following code...

private protected:
virtual void Dispose(Boolean disposing) override
{
   if(disposing)
   {
if (components != nullptr)
{
delete components;
}
   }
   __super::Dispose(disposing);
}

... for this another one:

protected:
  ~frmSigner()     // ~ symbol and the class name
  {
   if (components)
   {
    delete components;
   }
  }

Actually, ~<class name> is the C++/CLI equivalent of C#'s Dispose(), not Dispose(bool). Dispose(bool) is used to help implement the standard dispose pattern, but could be named anything. The latest build of Instant C++ renames Dispose(bool) to DisposeObject(bool).

I also thought that Microsoft would have one - they may have one available soon. Beyond that reason, there are a couple of further reasons we probably won't consider it:

1. I don't think Managed C++ has enough active developers to warrant it.

2. To develop a converter from C++ to anything else (even another 'version' of C++) is notoriously difficult. That's why you won't find any converter that converts C++ code to anything else.

In the final version of Visual C++, Dispose methods don't appear in windows forms.

Change the following code...

private protected:
virtual void Dispose(Boolean disposing) override
{
   if(disposing)
   {
if (components != nullptr)
{
delete components;
}
   }
   __super::Dispose(disposing);
}

... for this another one:

protected:
  ~frmSigner()     // ~ symbol and the class name
  {
   if (components)
   {
    delete components;
   }
  }

Very cool product - would you ever consider writing a Managed C++ to C++/CLI converter I think Microsoft was supposed to release one but never did.
Dark Helmet

I just pasted the converted code into an existing C++/CLI project and it only required one adjustment regarding DialogResult::OK.

Other than that one adjustment, the code compiled fine with Visual Studio 2005.

I'm not sure what the problem is - you're compiling with 2005 - right
