Wouldn't you get it the same way you get any other windows dev lib? :shrugs:
That is to say, go here[^] and download the windows SDK.

From Superman's link, you can see it's been supported since Windows ME, so any SDK released between then and now should do the trick nicely.

Getting error while sending data from client to Server in Socket using TCP/IP

Friends,
I have created two application Server and Client connected with Socket(TCP/IP). Now If i send the data from client to server then i getting error in this line ar.WriteObject(&m_sListOut);" . I have cited the code below.

Code:

C++

//Socket created and connected with server application
pSocket->creat();
pSocket->Connect(IPaddr,Port);

m_File = new CSocketFile(pSocket);
m_pArchIn = new CArchive(m_File,CArchive::load);
m_pArchOut = new CArchive(m_File,CArchive::store);

void SendDataToServer( )
{
  CTransData oData;       // deriver from CObject class
  oData.m_sListOut.AddTail(sPackData);
  pSocket->SendData(&oData);
}

void SendData(CTransData *pData)
{
  if (m_pArchOut != NULL)
  {
	TRY
	{
	   pData->Serialize(*m_pArchOut);
	   m_pArchOut->Flush();
	}
	CATCH(CFileException, e)
	{
	  m_pArchOut->Abort();
	  delete m_pArchOut;
	  m_pArchOut = NULL;
	}
	END_CATCH
  }

}

CTransData.cpp

void CTransData::Serialize(CArchive& ar)
{
   if (ar.IsStoring())
   {
       ar.WriteObject(&m_sListOut);     // In This Line I get Error
   }
   else
  {
      m_sListIn = (CStringList*)ar.ReadObject(RUNTIME_CLASS(CStringList));
  }

}

I have written same code in the Server side application and server is able to send the data to client without any problem. In case of Client, could not send the data to server side. Knidly help me to fix this problem

You need to provide full details of what that error is.

One of these days I'm going to think of a really clever signature.

You need to use your debugger to check the stack trace and find out where your program is calling out to this module, and what is causing the assertion.

Exactly what trouble are you having? Are you able to add other controls to the dialog? Is this an IDE or C/C++ (i.e., code) issue?

Just send it as a stream of bytes. As long as both ends of the socket use the same packing then you should have no problems.

1. Define a message structure. This will consist of either binary or text data.
2. Write and API/code that sends and receives.
3. Then call your API passing your structure.

The specifics of 1 depend on your business needs.
The specifics of 2 depend on the original structure and how you write 2.

How to color the TRACE output in Visual C++ 6 debug mode?

So I'd like to use colors in my "debug" windows during debugging. Is this possible? It would be really nice because I would be able to color different types out output messages...

I'd like to say something like
SetTraceColor(BLUE);
TRACE("blabla");

Thank you

Apply DS_SYSMODAL style when creating a dialog at runtime

Hi,

I need to apply DS_SYSMODAL style while creating a modeless dialog at runtime based on a registry key setting.And also undo this style from dialog at runtime. When DS_SYSMODAL is set, Windows is internally setting it to WS_EX_TOPMOST.

Now Can anyone tell me how I should do the same.
I have used ModifyStyleEx as below but it didnt seem to have any impact.

if(blnSysModal)
{
m_dlg1->ModifyStyleEx(0,WS_EX_TOPMOST);
}
else
{
m_dlg1->ModifyStyleEx(WS_EX_TOPMOST,0);
}

Any help on the same would be appreciated.

Thanks
Satya

DS_SYSMODAL is not used any more, it is no longer possible to have system modal dialogs.

the function CWnd::CreateControl succeeds, but m_hWnd is NULL

Here is my code:

C++

BOOL CDemoDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    // Set the icon for this dialog.  The framework does this automatically
    //  when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE);         // Set big icon
    SetIcon(m_hIcon, FALSE);        // Set small icon

    // TODO: Add extra initialization here
    CRect rect;
    GetClientRect(rect);
    CWnd wnd;
    BOOL bRet = wnd.CreateControl(_T("WMPlayer.OCX"), NULL, WS_VISIBLE, rect, this, 19089);

    return TRUE;  // return TRUE  unless you set the focus to a control
}

I run the code wich VC++ 6.0, everything is OK. But when run the same code under Visual C++ 2010, the handle of

C++

wnd

(namely

C++

m_hWnd

) is always NULL. Besides, the return value bRet is TRUE(namely success).

I'm confused. Anyone can help me?

As soon as you return from this function wnd goes out of scope and is destroyed.
