Have you debugged it? Where does single stepping break? What does the stack trace look like?

You should learn to use your debugger, it is much more efficient then asking questions on a forum.
Press F5 to start debugging and check where the crash occurs, this could already give you some information. Then put some breakpoints before the crash and debug once again to inspect the values of the different variables...

Which implies that if you remove the custom control, the error should go away. Yes?

Does the control need to be registered?

I have an application developed in mfc. Its a dialog based application. there is structure containing some members in it. I need to display the structure members in a listbox. how can i achive this?

Do you want to pass your structure directly to list box function and in according that list box is added with new item, is it your need?

if so then derive a class from CListBox and overload a function AddString()
say

CListBoxEx and your structure is
struct EXData

overload a function

int AddString( const EXData& MyStruct ); Smile | :)

create a reference vector of class objects

Hello

I want to create a refernce vector of class object in vs 2008.I m doing in vs2002 like

vector<piece> &m1 = garment->get_m1();

Piece is my class.

but when i m doing same in vs 2008,It is creating problem during m1.push_back().

Actually,as i think it is not getting Initialized properly,
So,Is any different way to use refernce vectors of class objects?

I suppose you should elaborate a bit (and show more code).

BTW could you please use the code block button when posting code snippets?

You need to clarify your question a bit.

First, please use the code block tags around your example code. Standard HTML does not render code properly

Secondly, you need to show the implementation (or a cut down version of it) of the get_m1 method

Thirdly, what is the problem that you are getting during m1.push_back?

I'm not sure what you mean by a "reference vector of class objects".

Do you mean a vector of references to class objects? If you do then this will not compile since it is not possible to have a vector (or any other container) of references. The type for std::vector must be assignable[^], and references are not assignable. Use a vector of pointers to objects instead.

Or do you mean a reference to a vector of class objects? This is at least legal and should work, e.g.

class Piece
{
};

class Garment
{
public:
  std::vector<Piece>& get_m1()
  {
    return pieces;
  }

private:
  std::vector<Piece> pieces;
};

static void foo()
{
  Garment garment;
  std::vector<Piece>& m1 = garment.get_m1();
  Piece piece1;
  m1.push_back(piece1);
}

ShellExecute does not work with utf-8 encoded files

Hi All.
I have a problem with opening an html file. The file is UTF-8 encoded.
My code is

ShellExecute(NULL, L"open", L"C:/PROGRAM FILES/MOZILLA FIREFOX/FIREFOX.EXE", L"file:///C:/DOCUME~1/MACADA~1/LOCALS~1/Temp/index.htm", NULL, SW_SHOWNORMAL);

it returns a value greater than 32 (success). But it opens a blank page. Sigh | :sigh:

When i look the page sources i can see that there is "Unicode conversion problem" is written in body tag.
If i try to open another file (ANSI encoded) it works properly.
Anyone have an idea?

Thanks,
Venera
