let me tel u in a simpler way,
my application waits for an event from a server. if the request is timed out, the application should terminate but shldn't freeze waiting for the event from the server.

//i tried to use a worker thread which will monitor the value of the
variable "eventDelay"
//so before requesting the event from the server, i'd do like this

int eventDelay=0;
CWinThread *ct=AfxBeginThread(threadtimeout,this);
getEventFromServer(&....,&....&....);
ct->SuspendThread();

//in the thread,(threadtimeout)

void threadtimeout()
{
do
{
Sleep(1000);
eventDelay++;
if (eventDelay>10)
exit(0);
}while(true);
}

but still the application gets hanged up if the server's not sending the event.. Frown | :(

. why..? how to timeout and exit?

regards,
Rookie

With the information you've provided it seems that you don't need a thread for that. You could use a simple timer (SetTimer) that terminates the app when fires up (OnTimer).

sorry for the bad naming convention... the function threadtimeout is not to timeout the thread.. its for timing out getEventFromServer() function... please help

Whenever you want to start the count in your dialog, insert:
....
SetTimer(0, 1000, NULL); // 2nd param is the miliseconds until WM_TIMER will be sent, in this case: 1 second.
....

When WM_TIMER is received, it fires up the ON_WM_TIMER event (usally mapped as OnTimer): you could use the VStudio Class Wizard - Message Maps Tab to make it easier.

void CYourDlg::OnTimer(UINT nIDEvent)
{
SendMessage(WM_CLOSE); //exit your app
}

Remove this. In no way should exit() be used to exit a Windows application, let alone one with multiple threads. See here for the proper way to terminate a thread.

Rookieee wrote:
Sleep(1000);

Why is this here? Using a gratuitous Sleep() like this indicates a bad threading model and adds no value. Reconsider why you think you need it.

hello all,
i am new to the group.i wanted to know how to parse a xml file using c++ where if the path of the file and the level of the node given that is the level where the element is present.then the parser has to go to the particular element and collect values of sub elements.
thanks

Visual C++?? You'll need to download MSXML[^]

How to SubClass a checkbox on a DialogBar

26-Jul-05 1:02

MSXML provide ways to navigate through the nodes. Use IXMLDOMDocument, IXMLDOMElement, IXMLDOMNode, IXMLDOMNodeList objects and its methods loadXml, get_documentElement, get_childNodes, get_item, nextNode, ...

So, depending on the integer that you receive you'll know how many iteration you need to do.

hi, all
a problem trouble me for a long time. Dead | X|

and i have been looking for the answer for a long time.
but i still can't solve it,i hope somebody can give me a
little suggestion. thanks in advance.

my dev platform: MFC 7 & Windows Server 2003
my question:

i want to subclass my checkbox on a dialogbar, and load my bitmap
to the checkbox's face.

all of my checkbox were set to push like style here
owner-draw mode was set to true .

in headfile MyDialogBar.h
====================================================

CBitmapButton m_btnCheck;<br />
BOOL InitButtons();

====================================================

in cppfile MyDialogBar.cpp
====================================================

BOOL CMyDialogBar::InitButtons()<br />
{<br />
   <pre>     m_btnCheck.SubclassDlgItem(IDC_TOOLBTN_SELECT, this);<br />
	m_btnCheck.LoadBitmaps(IDB_BITMAP_ICON_SELECT);</pre><br />
}

====================================================

in headfile MainFrm.h
====================================================
CMyDialogBar m_myDlgbar;
====================================================

in cppfile MainFrm.cpp
====================================================

int CMainFrm::OnCreate(...)<br />
{<br />
<pre>	if(!m_myDlgbar.Create(...))<br />
        {<br />
           TRACE0("sorry >_< ");<br />
           return -1;<br />
        };	<br />
	m_myDlgbar.InitButtons();</pre><br />
}

====================================================

Notes：
IDB_BITMAP_ICON_SELECT is a ID of bitmap resource file created by resource editor , i want this bitmap loaded on the checkbox button.

IDC_TOOLBTN_SELECT is the ID of the CheckBox

the checkbox can works fine, but i just cannot put my bitmap on it. why??
Confused | :confused:

i used to subclass my checkbox and load a bitmap on its face for many times
in common dialog application , there is no problems. why i use it in dialogbar, it doesn't work, and no error occured , the checkbox button works
fine. Confused | :confused:

i found something seems to be useful on MS KB, i rewrite my code , and it still does not work, D'Oh! | :doh:

http://support.microsoft.com/kb/185672

anybody here met this problems before?
can you get me out of this swamp Cry | :((

? can anybody post some related sample code or links here ? thank you very much Wink | ;)

any suggestion should be appreciated! Smile | :)

sincerely,
nickong

Kerberos SSPI fails to mutually authenticate

marshman25-Jul-05 22:14

Hi all,

Hoping someone has experienced this problem and knows of a solution or can
explain whats going on...

I have tried using both a managed c# wrapper taken from the Microsoft SSPI
Samples and unmanaged C++ to test how SSPI and Kerberos works.

It appears to all work quite nicely except for when I try to trip it up.

Imagine the case where the client is running as User A and wishes to connect
to User B. On the client side, I make a request to InitializeSecurityContext
to User B and begin the handshaking process. However, the server is actually
running as User A as well. I would expect the authentication to fail every
time, it doesn't. If the machine has just been rebooted, it seems to "work",
in that I get a SEC_E_WRONG_CREDENTIAL result on the client side. However if
I lock the computer and then unlock it (or even after a restart on a W2K3
domain) the context is successfully established.

Anyone experienced this before or know why it happens?

As for replicating the "issue", use the MS .NET Remoting SSPI sample
client/server control panels to replicate the scenario explained above.

Any suggestions, explanations, workarounds would be appreciated.

P.S. I'm running the code under a Windows 2000 domain (same
happens on a W2K3 domain as well).

Hi, I want to change background color from list control when it's disabled (WS_DISABLED)--> default gray. I create list control without dialog editor but on the fly

(*.h)
CListCtrl *m_List;

(*.cpp)
if (!m_List->Create(WS_VISIBLE | WS_DISABLED | LVS_LIST))
{
// error
return 0;
}

Thank you for your help.

In order to get some answer, you'd need to provide more data about what you are doing and what errors you are seeing. Check out the entry on this FAQ: What's the best way to ask a question about code, so that I get a good answer?[^]

Depending on whether I am running as a console app or a windows app, I want my logger to write to stdout or to a log file. Any ideas for doing this?

Jose Lamas Rios25-Jul-05 20:33

25-Jul-05 20:33

What is your logger? Is it a library or DLL? If so, any app you write (and you know if you are making a console or GUI app) can initialize the logger with that information... What I am missing?

Maybe calling GetStdHandle()? If the application doesn't have associated standard handles, it will return NULL...
