I found the new way to succeed, only this lines of code do the job

HCURSOR hCursor = LoadCursorFromFile("res\\AnimatedCursor.ani");
if(hCursor)
    SetCursor(hCursor);

Off course 'AnimatedCursor.ani' is the name of my source file.
But another problem appeared when running under release mode, cursor is not loading. Why?

It's a little sadly when talking to my self, isn't it?

Well I can get really stupid some times can I?
The file needs to be distributed along with application or it can not find and load it.

Obviously if I want it to work I need to go back and include my ani cursor in my resource.
But I cant get it to show (see previous posts). Does anybody know the solution to my problem?

What problem? How do you implement it.

You need to google first, if you have "It's urgent please" mentioned in your question.

I have Two Dialog box. Abc and Def ok. From Add button of Abc i have created Def Dialog box. I need to do some work in Abc on OK of Def.

CODE:
// Abc.cpp
#define USER_MSG WM_USER + 100

BEGIN_MESSAGE_MAP(Abc, CDialog)
//{{AFX_MSG_MAP(Abc)
ON_MESSAGE( USER_MSG, DoSomeWork )
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

void Abc::OnAdd()
{
Def d;
d.ptrParent = this;
d.DoModel();
}

void Abc::DoSomeWork()
{

}

/// From def.cpp
void def::OnOK()
{
if( ptrParent )
::sendMessage( ptrParent->m_hWnd, WM_USER + 100,0,0);
// i can do like ptrParent->DoSomeWork() but i wants to user USER MSG.
}

Thank you for your interest.

Why you need messages for this purpose??
You can simply do something like this..

void Abc::OnAdd()
{
  Def d;
  d.ptrParent = this;
  if(d.DoModel()==IDOK)
  {
      ...
     // here you can acess data members of the class def using d directly..
  }
  else
  {
    ... 
  }
}

I hope it helps..

I have no idea how you are doing this..
Anyways if you want to learn user defined messages
check following articles.
How to send a user-defined message with SendMessage, PostMessage or PostThreadMessage[^]
and HOWTO: MFC user defined message maps[^]
I will suggest to use RegisterWindowMessage instead of WM_USER. There reasons why you should avoid using WM_USER you can just google to read more on it.
I hope it helps.

Sandip.

~~If your child dialog is modal dialog, then the message processing of parent wil be blocked~~. Better passing parent window pointer to child dialog and call the desired function.

Check this to know how to create user defined messages[^]

Because you are not handling the WPARAM and LPARAM.
Even if you do not wish to use them you have to handle them.
Modify
DoSoemthing()
to
DoSomething(WPARAM wParam, LPARAM lParam)

I hope it helps.

The message handlers should have to format afx_msg LRESULT (CWnd::*)(WPARAM, LPARAM).
which means the void CPortsDialog::UpdateServerList( )

should be changed to LRESULT CPortsDialog::UpdateServerList(WPARAM, LPARAM)
