Are you referring to a service?

"Running in background" is not a term used in Windows as it is a multitasking environment.

Have you researched Shell_NotifyIcon()?

You can do it .
Go to VC++-->New -->Projects-->Win32 Application -->Give project name-->Choose Simple Win32 Application . There you go ..
You can see an application with WinMain() ..No windows nothing as long as you dont want it ...
It willbe part of TaskManager but for making it have a icon in tray you have to refer some docs

I think you are confused. Creating a text-based application, as opposed to a GUI-based application, has nothing to do with running in the background. The term "background application" is a holdover from Unix. Windows, unlike DOS, is a multitasking environment. With DOS, you could create TSRs. With Windows, that is not necessary.

cdhtmldialog is a powerful class which extends a common mfc dialog. but there are some problems which i don't know how to solve:
- how to disable backspace (VK_BACK), that the user can't go back in history but still enable it if user edits a text in a textarea or textfield ()? is there a way to determine in which context the backspace is used?
- how to disable 'shift'+leftmouseclick on a link which results in opening a new (fully ie featured) window?
- and the last point: how to catch a click event on a button with a specific id, which is part of a page where i don't know the url in advance (i only know the id of the button)? cdhtmldialog starts with a html page that is part of the resources and user can proceed to several online pages on which he can finish/close a process by clicking on a button with a specific id!

Hello, all!
Tell me please, how I can create a splitter in main window in MFC MDI? (Visual C++ 6.0, without WTL)
|
|
|
|

i'm not sure to totally understand your question, but you can create a splitter in the Child Frame window by using a CSplitterWnd in it.
Add a CSplitterWnd attribute to your child frame, then overload the virtual method virtual BOOL CFrameWnd::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext); to create the splitter window object:
For example:
BOOL CSplitterFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
if (!m_wndSplitter.CreateStatic(this, 2, 1))
{
TRACE0("Failed to CreateStaticSplitter\n");
return FALSE;
}
if (!m_wndSplitter.CreateView(0,0,
pContext->m_pNewViewClass, CSize(50, 50), pContext))
{
TRACE0("Failed to create first pane\n");
return FALSE;
}
if (!m_wndSplitter.CreateView(1,0,
pContext->m_pNewViewClass, CSize(50, 50), pContext))
{
TRACE0("Failed to create second pane\n");
return FALSE;
}
SetActiveView((CView*)m_wndSplitter.GetPane(0,0));
return TRUE;
}
Have a look to http://freedom2.pcupdate.easyspace.com/nt/ch07/182-186.html[^] for more info.

Hello,
Whenever the application's InitInstance is executed, what is the best way of preventing the OnFileNew method from being called without removing the command line parser? Is this possible to do without recurring to the use of flag variables?
|
|
|
|
|
isn't OnFileNew() a function of the CView or its derived class? I'm not sure, but can't you just override in your derived class and not call the base class's function?

If I have an "x" number of threads that I need started and will be passing messages to and from. Can I set my thread creating function like....
<br />
<br />
CWinThread myThread[nThreads];<br />
<br />
for (int i = 0; i < nThreads; i++)<br />
{<br />
myThread[i]= AfxBeginThread(MyThreadProc, this);<br />
}<br />
<br />
Thanks for the help.

I just checked and AfxBeginThread returns a POINTER to a CWinThread.
You might want to do this instead:
//nThread = the number of threads I need to start
CWinThread* pMyThreads[nThreads]; // <-- note array of POINTERS now
for (int i = 0; i < nThreads; i++)
{
pMyThreads[i]= AfxBeginThread(MyThreadProc, this);
}
I think that will work.

I need to be able to fetch bulk records on tables that contain binary columns such as images.
RFX_Binary_Bulk seems to be limited to INT_MAX and I didn't find something like RFX_LongBinary for bulk.
Any suggestions ?

I know with using ADO, you use GetChunk(). maybe you can find something equivalent for what you are doing.

Well, the title could be a little misleading. I have a CFormView as my main 'dialog'. I have a modeless dialog that I use for a chat window. When a user minimizes the main window, I want the chat window to still be visible. I've tried changint the style of the chat window to 'child','popup', and 'overlapped' and it still doesn't work. Likewise, I'd also like the chat window to show on the desktop without the main form if the main form is minized when new chat comes in. Right now the chat window isn't visible after receiving a message until the main window is restored. I've also tried using the hWnd of the desktop when creating the dialog, but that still doesn't help. Any suggestions are appreciated. Thanks!!

The only other thing I thought to try really quick was to give it a NULL parent.
Failing that, you might not be ablke to make it a 'dialog' at all, and will have to make it a full-blown window - a regular window derived from CWnd doing its own processing. Then it should be relatively independent of the main window.
|
|

|

thanks! I already tried the NULL parent thing also, and that didn't seem to work. I changed the SetForeGround property to true, and that seems to make it work for when I receive a message, but it still minimizes with the main app, so I'm thinking of seeing if it' actually a window when I minimize, and if so, show it again, the way I regularly do.

I think this is because MFC is traversing the window chain and 'windows' associated with the main user interface thread and just minimizing the whole lot of them when it is going down.
IF you were to place your modeless dialog into a separate user interface thread and parent it to the desktop it might not get minimized with the rest of the applications windows.
I have not tried this before, but that is the direction I would head next.
|
|
|
|

I fixed it in the CMainFrame class so that when my app is minimized, it makes a call to these three functions:
pView->m_pDlg->ShowWindow(SW_SHOW);
pView->m_pDlg->SetForegroundWindow();
pView->m_pDlg->SetFocus();

Three methods for dealing with dangling pointers are tombstones, lock-and-keys and garbage collection. What are the advantages and distadvantages of these ?

You should really do your own homework, but I'll help you out just this once...
Tombstones
(adv) Not limited by the system's run length encoding limits.
(dis-adv) Can only be used once in an application.
Lock & keys
(adv) Easy to implement.
(dis-adv) Cannot be used in Unicode mode or when an app needs to divide by zero (eg: during complex mathematical computations).
Garbage collection
(adv) Can be used for procedures as well as functions.
(dis-adv) Not supported in languages like Java or C#.
