Why don't you ask this question again so that we may see it a fourth time? Roll eyes | :rolleyes:

Hi to all,
I'm having trouble with CListCtrl. When I click on list it works only if I click on a small region on far left side.
One member of this forum advised me to use LVN_ITEMACTIVATE message. Problem is that I cant find it, I'm using VC++ 6.0!?
Thanks for replay's.

You can use class wizard to add a member function for message LVN_COLUMNCLICK.
Now go to code and replace this message LVN_COLUMNCLICK with LVN_ITEMACTIVATE.
Its' done Smile | :)

In the creation or initialitation of your control you should tell the control to accept what you want.

void CParamRegTabView::InitializeView()
{
// List initialization
	// List styles
	DWORD dwStyle;
	dwStyle = LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;
	m_clcList.SetExtendedStyle (dwStyle);
//...
}

and then just use:

void CMyTabView::OnClickMyTabRuleList(NMHDR* pNMHDR, LRESULT* pResult) 
{	POSITION pos = m_clcList.GetFirstSelectedItemPosition();
	if (!pos)
	{	m_nRowNum = -1;
		UpdateData (FALSE);
	}
	
	while (pos)
	{	int nPos = m_clcList.GetNextSelectedItem(pos);
		m_nRowNum = nPos;
		UpdateData (FALSE);
	}

	Invalidate ();			UpdateWindow ();
	*pResult = 0;
	return;
}

and

void CMyTabView::OnItemchangedMyTablist(NMHDR* pNMHDR, LRESULT* pResult) 
{	NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
	
	POSITION pos = m_clcList.GetFirstSelectedItemPosition();
	while (pos)
	{	int nPos = m_clcList.GetNextSelectedItem(pos);
		m_nRowNum = nPos;
		UpdateData (FALSE);
	}
	
	*pResult = 0;
	return;
}

Actually you dont need the m_nRowNum, but I do... to know the index of the selected element and use it to look for and other things.

Once more thanks for your's replay!
I've solved the problem on a way similar to NishantB++ solution.
The important is that this works now.
Bye.

It sounds as though you need to use the LVS_EX_FULLROWSELECT style.

Hi all,

If one looks in the eventviewer of Windows, there is a field called Event, which contains a number that idetifies the event. When I make use oif the struct EVENTLOGRECORD and one of it's members DWORD EventID; I receive a value of pevlr->EventID 536870913UL (0x20000001) , but in the event viewer the value is one. All other information is correct except this, am I doing something wrong, or you can I get hold / convert the EventID Variable.

Many Thanks

	if (hResult !=S_OK){ 			
		throw(HResultException("CoMalloc ResolveMsg",0));						
	}

I think you may want to call CoCreateInstance()

Unless he modified his post, that function is being called. Confused | :confused:

I have written an ATL COM server in a DLL with merged proxy/stub using Visual Studio 2005. It can sometimes be used locally and other times remotely. Deploying locally is straightforward and I've now got a client using it that way. However I've been wading through all sorts of internet articles, discussions etc. about how to deploy, debug, and use the component remotely, but to no avail.

I need to be able to deploy and debug on a remote machine via peer-to-peer and/or ethernet switched networks, including guidance on how to configure the security correctly on Windows XP Prof. with SP 2. I've got to believe that somewhere there is a 'step by step' guide on how to do this, but I haven't found one yet.

Please can anyone help?

Thanks.

Interesting...
How you discover that that's the function?
By reading all the 10000 pages in strict alphabetical order?

No, just the ones up to the function that you are interested in. All the pages after that do not need to be read, unless you just wanted to.

Hi, here is another option

BOOL IsDirectory(TCHAR *szPath)
{
	BOOL bRet = FALSE;
	DWORD dwResult = GetFileAttributes(szPath);
	if(dwResult != 0xffffffff  &&  (dwResult & FILE_ATTRIBUTE_DIRECTORY))
	{
		bRet = TRUE;
	}
	return bRet;
}

Best Wishes,
