thnx for your concern. I have an MDI application which shows some opengl scenes. From the mainframe, i have several views from the menu. What i wanted was when i click an option from the menu, a different view appears but which need not necessarily show opengl scenes. maybe some blank window with some text in it. (data used comes from the previous opengl scene). Now since i am not able to do this, i am planning to use a subwindow which appears in the mainwindow. Ie a blank window (small one at top corner of screen)?? Any suggestion....

Given that everything in Windows is a window in some form or another, your question is a bit vague. What exactly is it that you are wanting to do?

What is it that you are unable to do? Having more than one view per document is a relatively painless process. For an example, see MSDN article Q99562. Also, see the "Multiple views" section of this article.

Hi,
I have created a service in C# which spawns four child processes for some specific purpose. However if the child process crashes bcoz of some reason then I need to create a new instance of the child process.
I am able to do this in C# as there are events triggered when an application shuts down.
Now for some reason I want to port the service to VC++. I want to implement the restarting feature in the service. Does any body have any idea about the same?
Regards,
Nitin Gautam.

Crashes as in GONE or crahses as in STUCK.
If you retain the four process handles for the four programs you started, they will be signaled when the application is 'no longer a process' but you have no idea if they are HUNG.
If I start a child process and want to know when it is gone, I just wait/watch for the child process' handle to be signaled.

hi,
under the WIN32API we have CreateMutex function...
u can use this function to check whether the appilcation is already running..
by its return values u can re-invoke the existing one...
Public Declare Function CreateMutex Lib "kernel32" Alias "CreateMutexA" (lpMutexAttributes As SECURITY_ATTRIBUTES, ByVal bInitialOwner As Long, ByVal lpName As String) As Long
this is the declaration for that function.(from API text viewer)
u can also find help in MSDN abt this.
http://support.microsoft.com/default.aspx?scid=kb;en-us;258088[^]
use this link...
heres a vb sample....
Option Explicit<br />
Const ERROR_ALREADY_EXISTS = 183<br />
<br />
Public Declare Function CreateMutex Lib "Coredll" Alias "CreateMutexW" _<br />
(lpMutexAttributes As Long, _<br />
ByVal bInitialOwner As Long, _<br />
ByVal lpName As String) As Long<br />
<br />
Public Declare Function GetLastError Lib "Coredll" () As Long<br />
<br />
Private Sub Form_Load()<br />
<br />
Dim error_code<br />
<br />
CreateMutex CLng(0), 1, App.Title<br />
If GetLastError() = ERROR_ALREADY_EXISTS Then<br />
MsgBox "Already running", vbOKOnly, App.Title<br />
App.End<br />
Else 'run the application<br />
MsgBox "OK to run"<br />
End If<br />
End Sub
all the best..

"... can use thread local storage to keep track of an object's internal data" from a cp article.
//now my doubt is
CMyObj ob; //my obj is stored inside stack.
CMyObj* pOb = new CMyObj(); //my obj is stored inside heap.
---------------- //now how to store in threads local storage ?
pls throw some light

look for TLS (thread local storage) in MSDN. Also the functions TlsAlloc, TlsFree, TlsGetValue, TlsSetValue might be helpful.
