Along these same lines, do you know how to put carriage returns into the CEdit? Yeah, I know, noob question, but I haven't worked much with CStrings and CEdit controls, and I just realized that putting a "\n" into a char buffer then converting it to a CString won't work in a CEdit...how do I do this?

~~I think you have to use "\r \r".~~

Edit...sorry that's wrong here...it's "\r\n".

that did the trick...thanks...seems counterintuitive, like I was programming for unix or something...I never even would have guessed that in a million years...

Also, a totally unrelated way of doing this, but may be of use if you're using a DLL, is to create a shared data segment with #pragam data_seg() and put in a global variable in there which will keep track of the number of instances of subscribers to the DLL. Of course your program will have to import the DLL etc, which is not preferable at all, but like I said if you're already using a DLL it's another option.

Right now, We have a ClxThreadClass that provides the capablity to create single worker thread for the class that inherits it. The function below shows the class member function that creates and starts the new thread. The desire worker code reside in _ThreadFunc.

<br />
<br />
The Current working design<br />
/*************************************************/<br />
bool ClxThreadClass::CreateNewThread()<br />
{<br />
     if( m_hThread == NULL )<br />
     {<br />
	// _beginthreadex(Security attributes, stack, Thread proc, Thread param, creation mode, Thread ID)<br />
	m_hThread = (HANDLE)_beginthreadex(NULL,   0,_ThreadFunc, this, CREATE_SUSPENDED, &uiThreadId);	<br />
        //<br />
	if ( NULL != m_hThread)<br />
	{<br />
		//SetThreadPriority(hThread, THREAD_PRIORITY_HIGHEST);<br />
        	ResumeThread( m_hThread );<br />
		m_bActive = true;<br />
		return true;<br />
	}else{<br />
		m_bActive = false;<br />
	}<br />
    }<br />
<br />
   return true;<br />
}<br />

However, We sometimes would like to use different function other than _ThreadFunc. How can we overload CreateNewThread member function to take an external and pass to beginthreadex. This external obect is not a member function of base or inherited class.

<br />
bool ClxThreadClass::CreateNewThread( void *ptr )<br />
{<br />
<br />
    if( m_hThread == NULL )<br />
    {<br />
	// _beginthreadex(Security attributes, stack, Thread proc, Thread param, creation mode, read ID)<br />
	m_hThread = (HANDLE)_beginthreadex(NULL,   0,	ptr, this, CREATE_SUSPENDED, &uiThreadId);	<br />
        //<br />
	if ( NULL != m_hThread)<br />
	{<br />
        	//SetThreadPriority(hThread, THREAD_PRIORITY_HIGHEST);<br />
		ResumeThread( m_hThread );<br />
		m_bActive = true;<br />
		return true;<br />
	}else{<br />
		m_bActive = false;<br />
	}<br />
    }<br />
    return true;<br />
<br />
}<br />

Maybe something like this:

typedef unsigned (__stdcall *PTHREADFUNC)(void *);
...
bool ClxThreadClass::CreateNewThread(PTHREADFUNC pThreadFunc)
{
if( m_hThread == NULL )
{
   // _beginthreadex(Security attributes, stack, Thread proc, Thread param, creation mode, read ID)
   m_hThread = (HANDLE)_beginthreadex(NULL, 0, pThreadFunc, this, CREATE_SUSPENDED, &uiThreadId); 
 
   ...
 
}

if this function points to global function, it will work .. if it point to class member function.. then there would be some trouble.. i.e. we have to change the Funtion ptr declaration and pass the pointer of the class to that function!

Right. The OP stated "This external obect is not a member function of base or inherited class"
which ~~sounded~~read like it wasn't a class method to me.

Is it possible to scroll a disabled listbox ? without having to create an owner drawn list.

I have a listbox that gets filled with data but its state is disabled, but I want to be able to scroll the list to see what is in there.

Or maybe I should simply reconsider the UI to allow an enabled list, but "tweaked" to make the list "disabled".

Thanks.

Max.

If you don't accept drag and drop, and make the list box "no selection," why disable it? The user can't do anything to it with those properties set. What are you trying to prevent that you make it disabled?
