References and (re)building.

Hello,

I am developing a dozen or so C++/CLI assemblies in my solution. When I apply even a smallest change to one of them (so the binary is updated on build), all other assemblies that refer to this modified assembly are getting fully rebuilt (along with their precompiled headers). It takes quite a lot of time, and seem completely unnecessary to me, as I am not modifying any interfaces, only implementations.

Is there a reasonable way to prevent the dependent assemblies from being rebuilt?

I need to create an 2 dimension array, wich type is picture box, so I have write such code:

<br />
private: static unsigned short int n = 100;<br />
private: static array  <  System::Windows::Forms::PictureBox^ >^ m; <br />
m = gcnew array <   System::Windows::Forms::PictureBox^  >  (n);<br />
for(int i=0; i < n; i++){<br />
  m[i] = gcnew array < System::Windows::Forms::PictureBox^ >(n);<br />
  for( int j = 0; j < n; j++){<br />
    m[i, j] = gcnew System::Windows::Forms::PictureBox();<br />
    m[i, j]->Location = System::Drawing::Point(200 + i, 250);<br />
    m[i, j]->Visible = true;<br />
    m[i, j]->Size = System::Drawing::Size(1, 1);<br />
    m[i, j]->SizeMode = System::Windows::Forms::PictureBoxSizeMode::StretchImage;<br />
    m[i, j]->Load("a.gif");<br />
    Controls->Add(m[i, j]);<br />
  }<br />
}

but i get an error, that this array is not 2 dimension
what can be wrong?

To create it in two dimensions, you need to create an array of arrays.

private: static array < array < System::Windows::Forms::PictureBox^> >^ m;

Hi,

It's about 5 day that I'm traying to create a MixedMode DLL with MFC and Managed C++. At this time I'm freak I don't really know what I'm doing. I have read a lot of documentation and I still confuse.
With more detail, I want to create an MFC Regular DLL that can be accessible in C# and from an other MFC application.

If any body have a good tutorial or a small project that implement the DLL, an application in MFC and an other application in C#.

Thank for your help.

Perhaps if you told us what the error is ?

If EventLog is a managed object, I thought you needed to use gcnew ?

Overriding c# assembly method with out parameter in C++ [modified]

I know the answer to this may be obvious but I have been struggling with it for about 8 hours now and just can't figure it out and my googling and other searchs have not yielded an answer.

I'm writng a managed C++ program in VS 2005 that is using some c# assemblies. I have one c# assembly method that has a signature like this:

public virtual void DoThis(string title, out Object valueToChange);

I have an example where some c# code is overriding the above method and the signature in the subclass is:

public override void DoThis(string title, out Object valueToChange);

In my C++ code I just cannot get my program to use my overriden implementation of this method. I have tried the following signatures in C++. None of them seem to match according to what I see in the debugger.

public virtual void DoThis(String title, Object % valueToChange);
public virtual void DoThis(String^ title, Object ^% valueToChange);
public virtual void DoThis(String^ title, Object ^ valueToChange);
public virtual void DoThis(String title, Object valueToChange);
public virtual void DoThis(String title, Object^ valueToChange);

public void DoThis(String title, Object % valueToChange);
public void DoThis(String^ title, Object ^% valueToChange);
public void DoThis(String^ title, Object ^ valueToChange);
public void DoThis(String title, Object valueToChange);
public void DoThis(String title, Object^ valueToChange);

What is the correct way to override an "out" c# method parameter in c++ code?

Thanks for any help

Have you tried:

using namespace System::Runtime::InteropServices;

...

public:
virtual void DoThis(String^ title, [Out] Object^% valueToChange) override;

Wow thanks so much! I did have to change 1 part of what you suggested to get it to work (No ^ on the 1st param) but now I am so happy. I had wasted so much time on this problem. I didn't know about the InteropServices namespace before. I'll have to read up on it.

public:
virtual void DoThis(String title, [System::Runtime::InteropServices::Out] Object^% valueToChange) override;
