I'm with you so far.

Are you talking about using GetItemText() or GetItem() in response to a LVN_ITEMCHANGED message?

This is unclear in so many ways.

Store it where, in the list control or some data structure?

Nonsense (assuming you are referring to the LVN_ITEMCHANGED message). That would only happen if you used SetItemText().

In a manner of speaking, yes.

(assuming I understand what you want)
If you have a "virtual" list ctrl (CListBox or CListCtrl?), then you should have an underlying data structure somewhere that holds the data that is displayed by the list.
In you derived list ctrl control, there should be a method to display each item individually something like DrawItem); usually, it's in that method that you fetch the data from your data structure and "format" it correctly to be displayed in the list ctrl.

Hello all
I have a big problem after upgrading to IE8 . In our filetransfer module we are using wininet_connect(..) to establish connections via gSoap client . It has been working fine till we upgraded to IE8 with wininet.dll version 8.0 . The problem is that the wininet_callback is getting INTERNET_STATUS_CONNECTION_CLOSED message due to which gSoap client is disconnecting . This does not happen in IE6 and its wininet.dll version ...
Has anyone faced this problem ?

Why don't execution function
MessageBox(L"DIVIDE BY ZERO"); ?
The code is skipping.
#include "Excpt.h"
#include "Winnt.h"
#include "cmath"
float fResult; // Bennet, pg.136
//int x,y;
float x,y;
// x = 5;
// y = 0;
x = 5.0;
y = 0.0;
_try // __try
{
fResult = x/y;
}
//__except (GetExceptionCode() == EXCEPTION_FLT_DIVIDE_BY_ZERO)
_except (GetExceptionCode() == EXCEPTION_FLT_DIVIDE_BY_ZERO)
{
MessageBox(L"DIVIDE BY ZERO");
}

You need to turn on floating-point exceptions first...
Try #includeing <float.h> and add this bit of code before you do the divide...
_controlfp(0, MCW_EM);

Hi all,
Can any body tell me how to disable restore on title bar click.
Thanks

I presume you mean restoring a window from a minimized state?
If so, then your main window needs to handle WM_SYSCOMMAND[^] and call the inherited WndProc EXCEPT when the wParam == SC_RESTORE.

Hi,
Following is the code I am trying to do
<#import "C:\\Program Files\\BOSS\\SUPPORT\\RealDWG\\cf2407.dll" rename_namespace("CADFilter")
AcRx::AppRetCode acrxEntryPoint (AcRx::AppMsgCode Msg,
void* AppId)
{
// local variables
int cindex;
CADFilter::NW_IDocument *m_pIDocument;
CLSID clsid;
CoInitialize (NULL);
HRESULT hr = CLSIDFromProgID(LPCOLESTR("NW_Document"), &clsid );
hr = CoCreateInstance( clsid, NULL,CLSCTX_ALL , __uuidof(CADFilter::NW_IDocument) , (void**)&m_pIDocument );
if(SUCCEEDED(hr))
{
AfxMessageBox(_T("Hi"));
}
}>
But I am getting an " HRESULT hr as an "Invalid class string"

Don't cross-post. Look in the COM forum, where I answered this question.

is NW_Document a valid ProgID? Have you checked it with, for instance, OleView Tool?

NW_Document is the name of my co class which i saw in .tlh file.
By the way how to get to know that the ProgID is valid or not and if not then what is ProgID

From MSDN [^]:
ProgIDs present a human-readable version of the class identifier (CLSID) used to identify COM/ActiveX objects.

OleView tool helps. You may also have a look at the registry.
