Thanks Hamid,

My problem is,

1. My application breaks (e.g. uncaught exception) and report the breaking address is 0x12345678;
2. I want to know what code are executed at 0x12345678, and what are the call stack from bottom to address 0x12345678?

Any ideas?

regards,
George

Do you have source code of your program?

Hi Hamid,

I am not talking about a specific program. But a general method to retrieve stack trace from a specific address. Any comments or ideas?

regards,
George

Well I think there are no API for it I think you must be use of OS low level APIs or even assembly but I think most programs have a special register of current stack and address of caller's stack adress that you can use of them,but if you need to a tools see here[^]

Thanks Hamid,

I prefer to use as least as 3rd party tools as possible. Currently, I am using WinDbg dv command, do you think this command could serve my purpose?

regards,
George

That looks like a Java store to me. Leaves me wondering why would one write an antivirus in Java. Big Grin | :-D

Yes, Java is good for internet programming but may not be for antivirus s/w.

Clamwin which you recommended looks nice as it related to c++.

That looks like too much of an ambitious project to me, considering the fact that you want to do it all alone.

If you are wanting to do it from the scratch, there's too much for you on the plate. Start with file filter driver, executables (binaries in general), and more and more.

Alternatively, Google for Clamwin.

TVITEM item;
item.mask = TVIF_STATE|TVIF_PARAM;
item.hItem = TVI_ROOT;
HTREEITEM lastItem;

do {
do {
lastItem = item.hItem;
if (lastItem != TVI_ROOT) {
TreeView_GetItem( m_hwnd, &item );
// DO SOMETHING WITH YOUR TREEVIEW-ITEM (item)
}
} while ( (item.hItem = TreeView_GetChild( m_hwnd, lastItem )) );
while ( (! (item.hItem = TreeView_GetNextSibling( m_hwnd, lastItem ))) && (lastItem = item.hItem = TreeView_GetParent( m_hwnd, lastItem )) ) {}
} while ( item.hItem );

It is working correctly.

At one phase i m using like this, there is only one change i m insert for loop now its not working correctly.

it is not read node one by one.It is read one node number of times.

<br />
TVITEM item;<br />
CTreeCtrl m_perm_tree;<br />
		HWND m_hwnd;<br />
		m_hwnd=m_perm_tree.GetSafeHwnd();<br />
		item.mask = TVIF_STATE|TVIF_PARAM;<br />
		item.hItem = TVI_ROOT;<br />
		HTREEITEM lastItem;<br />
CString setpermstr;<br />
		int length=0;<br />
		length=setpermstr.GetLength();<br />
<br />
		<br />
	do {//do 1<br />
		do {//do2<br />
				lastItem = item.hItem;<br />
				if (lastItem != TVI_ROOT) <br />
				{//if<br />
					TreeView_GetItem( m_hwnd, &item );<br />
			<br />
					for(int i=0;i<=length;i++)<br />
					{<br />
						if(setpermstr.Mid(i,1)=="1")<br />
						{<br />
							<br />
							m_perm_tree.SetCheck(item.hItem,1)	;<br />
							<br />
						}<br />
						else if(setpermstr.Mid(i,1)=="0")<br />
						{<br />
							<br />
							m_perm_tree.SetCheck(item.hItem,0)	;<br />
							<br />
						}<br />
					}<br />
				}//if<br />
			} //do 2<br />
			while ( (item.hItem = TreeView_GetChild( m_hwnd, lastItem )) );<br />
<br />
			while ( (! (item.hItem = TreeView_GetNextSibling( m_hwnd, lastItem ))) <br />
			&& (lastItem = item.hItem = TreeView_GetParent( m_hwnd, lastItem )) ) <br />
		{}<br />
		}//do1 <br />
		while ( item.hItem );<br />
		<br />

Please help me for this.

Problem with system command:

T.RATHA KRISHNAN25-Jun-08 18:49

25-Jun-08 18:49

Hi!
In my Program I've called the system command in the start event of a button like this:

static bool startHandler(const CEGUI::EventArgs& e)
   {
	   //dtABC::Application::GetInstance(0)->Run();
	   system("CharacterAnimation.exe");
	   return true;
   }

This compiles fine. When I ran my Program and clicked the start Button, a message was displyed which says:

'CharacterAnimation.exe' is not recognized as an internal or external command, operable program or batch file.

What to do to run the 'CharacterAnimation.exe' if I click the start button?

See ShellExecute(/*parameters*/); You need to specify the full path of the exe

Somethings seem HARD to do, until we know how to do them.

Thanks. It's working now. But I've put the exe in the Release folder of the calling project. Why it didn't work? Can u explain?

_AnsHUMAN_ 25-Jun-08 19:22

25-Jun-08 19:22

The system command was not knowing the location of the exe you were trying to run. Try putting the full path of the exe in the system command and it should work too.

Ok. It's working fine. But When I terminate the called exe, the control didn't pass to the parent Window. i.e after I closed the called exe, the start and exit buttons in the parent window are not clickable. What to do to resolve this?

_AnsHUMAN_ 25-Jun-08 19:34

25-Jun-08 19:34

What do you mean by "buttons in the parent window are not clickable". What exactly happens when you click somewhere on the dialog? Does the dialog show up as the active window? Did you try and debug the code, if affirmative then are you able to enter the function and debug it?

When I click the Start Button in a Window an exe(CharacterAnimation.exe) will be run. When I close this exe(CharacterAnimation.exe), the first Window which contains the start Button and one more called exit Button is not clickable. What to do to resolve this problem?
