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.

Thank you

Perhaps if you told us what the error is ?

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

GetHostName is a static method:

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;

Thanks,

You could set Value to 0.

How to move the IME window?

I have developed a text editor supporting international languages.
One problem still bother me: The location of the IME window.

When I have an asian user entering asian characters, (s)he does so through an IME window which is located in a seemingly unpredictable/uncontrollable location.

Is there a way I could set the location, size, and font (or at least font size) used by this IME window?
How could I know when it is used or not?

I would use listView, but i don't know how ican add 2 item i try:

istView1->Items->Add(cli::array<string^>^ tabChaine = {"Element 1", "Element 2"});

but there are errors,Thank you

Re: listView

Mark Salsbery8-Mar-07 10:22

What are the errors?

I don't see a ListView.ListViewItemCollection.Add overload that takes a "cli::array^" as an
argument.

Also managed object references don't work like C++ pointers so this won't work:
cli::array^ tabChaine = {"Element 1", "Element 2"}

Have you seen the example code here[^]?
