UINT WorkerThreadProc(LPVOID Param)
You can access to the parameters through Param variable, if you are not still using that:
interpret it as a pointer to the dialog that contains the variable members, and then reach the values .
If you are using Param in another way you could create a struct where you can store every information that needs to be passed to the thread.
But, be carefull : if you create a local (like in OnInitistance)instance of the structure, that will be destroyed when the function ends, i.e. before that the thread ends,....so goodby to the paramenters
You can solve this problem using a memeber variable into the first dialog or with dynamical memory allocation (but others problems cames to free the memory ).
hope be clear

Hi _Russell_,
Thanks for the wondeful reply and thanks a lot for giveing lot of information.
I am very much new to VC++ and threds ,i just learned threads by some sample notes i am really very new to it ...
can u please tell me how i have access the values in the thread without any problem can u please tell me with some examples or some code please..
BOOL CStatusDlg::OnInitDialog()
{
CDialog::OnInitDialog();
m_ctrlSNAME.SetWindowText(sfile);
m_ctrlSLOCATION.SetWindowText(slocation);
CString str;
HANDLE hr;
hr = CreateThread(NULL,0,(unsigned long (__stdcall *)(void *))WorkerThreadProc,this,0,0);
return TRUE;
}
--------------------------------------------------------------
UINT WorkerThreadProc(LPVOID Param)
{
CStatusDlg status;
//CString loc = status.slocation + status.sfile;
char * d =(char *) (LPCTSTR) loc;
return true;
}
------------------------------------------------------------
please give me some solution so that i can access values from InitDialog and ican use them in Thread.

You'll need to use AfxBeginThread() here.

status will need to be a pointer to a CStatusDlg. You need to cast Param to this.

Hi,
I have a customised menu class derieved from CMenu.
I have overridden the DrawItem n MeasureItem functions.
The problem is with having title for child menu.
I'm addin childmenu through
AppendMenu(MF_POPUP | MF_GRAYED | MF_OWNERDRAW , nID, (LPCTSTR)color))
now if I want to have a title for submenu eg:colors in the below case
shapes
colors->green
red
sizes
how can that be done.
Even if I use InsertMenu() then again there is a problem,we cannot have OwnerDraw n
MF_STRING together.
Is there any solution for this?
Thanks.

Hi,
You can use GetFileAttributesEx -> if dwFileAttributes from WIN32_FILE_ATTRIBUTE_DATA struct will have FILE_ATTRIBUTE_DIRECTORY - so it's directory

hi,
try CPath::IsDirectory(). But it is an ATL class. You have to include atlpath.h
Adios,

No, there is no difference, NULL is defined as 0.
It's just that using NULL for a pointer is more convenient (to make the difference with the 0 value).

Hi
No difference between NULL & 0
In VC header file NULL is defined as 0
KK

There isn't sintax difference, look at the macro:
#define NULL 0
but there is a logical difference:
pointers doesn't contains numbers but addresses, so p=0 is logically incorrect, it must be set to the default null address(NULL). That, of course, for convention and semplicity it is set to 0.
Using NULL is only a way to write more readable code.

In C++, nothing. In C, lots. A standard C compiler won't automatically convert 0 to a pointer, so you'll have to assign (void*)0. In C, NULL is defined as ((void*)0) to allow you to set a pointer to 0. In C++, the compiler will happily convert 0 to a pointer, so you don't need the cast, and NULL is simply defined as 0.

Hi ,
i m trying to create an scrollbar as an activeX component which resizes itself based on image it is attached .
Please reply ASAP
suren

We are using a CComboBoxEx with style set to droplist to display a lsit of images.
When the drop down list appears and we click on the combobox (not on the drop down arrow),
the dropdown list closes as expected but then it immediately reopens!
How to prevent this behavior?
If instead we click on the drop down arrow when the list is open it decently closes without reopening.

Hi All,
I have an owner-drawn list box.
now my task is to fit a scroll bar for that.
when im trying to get the scroll position using CLisbox::GetScrollPos, it is always returning 0. how we can determine the current scroll position?
Currently im scrolling teh items by sending SendMessage(WM_VSCROLL,MAKEWPARAM(SB_LINEUP,0),0); function. will this update the current scroll position. in a normal list box im exactly getting the scroll position, but with owner-drawn one, im not getting.
anyone can suggest a solution for this problem? I need to draw the scrollbar as the part of lisbox not as a seperate control.
now tracking teh thumb is the main issue. pls help me to come out from this.
