Various code here will be more or less forgiving, a lot of my articles will compile on any C++ compiler, as they are about standard C++. Most will require Microsoft Visual Studio 6.0 or .NET.

Seriously dude, if you can't work out that a site that has articles on programming the Microsoft platform will need the Microsoft compiler, even if sommeone was silly enough to attempt the huge answer required for such a broad question, the odds of you understanding the answer are close to zero.

Hello folks,

just moved from unix environment into win32, not quite comfortable with the feeling that i'm a dumb yet again Frown | :(

please, help! i need to get a full path to user's dir's like "My Documents". How can i do that? Just hardcoding the path "c:\\Documents and Settings\\USER_NAME_WHO_THE_HELL_KNOWS\\My Documents" is not good idea at all. And what about compatibility with different windowses (nt, xp, win2k or even win98)?

any help is greatly appreciated Smile | :)

In the specific case you mention, start here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/programmersguide/shell_basics/shell_basics_programming/manage.asp[^]

MSDN has compatability information on each API - you should install it from the CD/DVDs if you have them, or use the MSDN web site.

Ack, don't do this. Microsoft might not always place that information there. Always use the proper API calls. It is hacks like this that cause programs to break.

True, although sometimes the proper API doesn't exist... or only exists if you have version 5.5 or higher of IE, or the API works great on 2000 but crashes on 9x... some other such bull.

No single raindrop believes that it is responsible for the flood.

I have been issued a new PC at work. It has both Visual Studio 6 and Visual Studio Dot Net 2003.
When I am running a Visual Studio 6 C++ program outside of the debugger and it crashes I get the abort retry cancel dialog. I press Retry to debug and I get a dialog asking me to select the debugger. Only Dot Net debugger is listed. How can I make Visual Studio 6 appear in this list?

Thanks

When should I delete ServerSocket when client shutdown

white jungle11-Jan-04 5:21

When client shutdown,it will send a FD_CLOSE to server and the server receive this message,then the server invoke the function OnClose().In this function I want to destruct the server socket object.BUt how can I?
In my program(it's a dialog based program with socket support),the var m_ConnectList used to record how many ServerSocket have been create.

<br />
void CBBSServerDlg::ClientConnect()<br />
{<br />
	m_pServer=new	CServeSocket();<br />
	if(m_Listen.Accept(*m_pServer))<br />
	{<br />
		m_ConnectList.AddTail(m_pServer);<br />
		m_pServer->Init(this);<br />
		UpdateData(FALSE);<br />
	}<br />
	else<br />
	{<br />
		delete m_pServer;<br />
		m_pServer=NULL;<br />
	}<br />
}<br />

this function will be called by a CListenSocket when it received a FD_ACCEPT.
So I want to destruct the serversocket object when client shutdown with the following code

<br />
void CBBSServerDlg::LostClient(CServeSocket* pSocket)<br />
{<br />
	ASSERT(pSocket!=NULL);<br />
	POSITION	pos=m_ConnectList.Find(pSocket,NULL);<br />
	if(pos!=NULL)<br />
	{<br />
		m_ConnectList.RemoveAt(pos);<br />
	}<br />
	pSocket->Close();<br />
	delete pSocket;<br />
	pSocket=NULL;<br />
}<br />

And of course the function is called by ServerSocket when received a FD_CLOSE.

<br />
void CServeSocket::OnClose(int nErrorCode) <br />
{<br />
	m_pMainDlg->LostClient(this);	<br />
	CSocket::OnClose(nErrorCode);<br />
}<br />
<br />

Now I have a question that if I call the function LostClient,the ServerSocket will be destroyed ,and the where the function returned.
But if I don't do it this way,How can I destroy the ServerSocket object when client shutdown

Thank you very much for your help!

Don't look at me in that way!

I am not familiar with winsock wrapper classes. Under raw winsock, one solution is closesocket().

As a matter of fact,I just want to know the things following.
I have two classes

<br />
claas B;<br />
class A<br />
{<br />
.......<br />
void create();<br />
void destroy(B *pB)<br />
}<br />
clss B<br />
{<br />
void SetAttach(A * pA){m_pA=pA;}<br />
A  m_pA;<br />
}<br />
.......<br />
A::Create()<br />
{<br />
   B b;<br />
}<br />
A::Destroy(B *pB)<br />
{<br />
  pB->destroy();<br />
  delete pB;<br />
  pB=NULL;<br />
}<br />

and if I invoke A::Destroy(B *pB)from class B

<br />
b::someFunction()<br />
{<br />
m_pA->Destroy(this);<br />
}<br />

I think it will be throw out a error because the function can't be returned when pB was deleted.
So I want to get a useful method to delete pB

For my poor,wish you can understand me!

Don't look at me in that way!

LV & TV strange behavior

GeraldoLuiz11-Jan-04 1:49

11-Jan-04 1:49

Hi, I've never used label editing in TreeView & ListView before, so I guess it's a simple question. I used the EditLabels property (LVS/TVS_EDITLABELS) and create the controls. But a strange thing happens. I click on the label to edit and it's ok, but when I press any key (in both the TV and LV) the dialog is dismissed. Also, when I press ENTER (without any char has been pressed), they behave differently: the LV accepts it but the TV close the dialog.
What is happening ? What is missing here ?

I create a very simple test: a new Win32 App,typical HelloWorld, and include this lines in teste.rc:

CONTROL "List1",100,"SysListView32",LVS_REPORT | LVS_SINGLESEL |
LVS_SHOWSELALWAYS | LVS_EDITLABELS | LVS_NOSORTHEADER |
WS_BORDER | WS_TABSTOP,7,7,132,30
CONTROL "Tree1",200,"SysTreeView32",TVS_HASBUTTONS |
TVS_HASLINES | TVS_EDITLABELS | TVS_SHOWSELALWAYS |
WS_BORDER | WS_TABSTOP,7,43,158,24,WS_EX_CLIENTEDGE

and include InitCommonControls(); at WinMain and
#include "commctrl.h" and put comctl32.lib in the project settings

finally I put this on the About function:

case WM_INITDIALOG:
LVCOLUMN col;
col.mask = LVCF_TEXT | LVCF_WIDTH;
col.pszText = _T("Col1");
col.cx = 100;
ListView_InsertColumn(GetDlgItem(hDlg, 100), 0, &col);

LVITEM lv;
lv.mask = LVIF_TEXT;
lv.pszText = _T("Txt1");
lv.iItem = 0;
lv.iSubItem = 0;
ListView_InsertItem(GetDlgItem(hDlg, 100), &lv);

TVINSERTSTRUCT tv;
tv.hInsertAfter = TVI_LAST;
tv.item.mask = TVIF_TEXT;
tv.hParent = TVI_ROOT;
tv.item.pszText = _T("root");
TreeView_InsertItem(GetDlgItem(hDlg, 200), &tv);
return TRUE;

and that's it. I didn't include the handlers to LVN/TVN_BEGINLABELEDIT and ENDLABELEDIT , but I think this is not the problem. Why the dialog is dismissed when I press any key ? Why the ENTER key is OK with LV but close the dialog in TV ? Did I forget to handle some message or notification here ?
Did they act differently in Windows and Dialogs ?
