Thanks for you replay.
WM_TIMER is same as Sleep(), if you set timer interval as 100ms. you are not guaranteed to run at 100ms even 200ms or 500ms.
For Multi-Media timer... I 'll try.

You can use the following method...
Create a thread that will do your work every 100 ms..
ULONG __stdcall LogRotater(LPVOID pParam)// declare a thread function
And define it as below
ULONG __stdcall LogRotater(LPVOID pParam)
{
BOOL bStop=FALSE;
WriteMessage(msg,1);
while (bStop == FALSE)
{
HANDLE m_hEvent;
m_hEvent=CreateEvent(NULL,FALSE,FALSE,NULL);
switch (WaitForSingleObject(m_hEvent, DWORD(100)))
{
case WAIT_OBJECT_0:
bStop = TRUE;
break;
case WAIT_TIMEOUT:
//Do your work here ...
break;
}
}
return 0;
}
in case: WAIT_TIMEOUT you can do whatever you want to ...

Hello,
I working on FindNextFile(); and it works greate, but i is a problem.
I check for *.txt files in the c:\\ and when I find a file I take the file name and show it in my dialog window but the thing want stop, If there is only one file then I can check the file name so I don't use the same file, But if there is more than one file the funktion check and load the same files over and over.
Is there anyway to check so I don't use the same file over and over again?
Hmmm I use this function on a timer so it checks every second.
Please help me.

If you are only wanting one file:
HANDLE h = FindFirstFile("c:\\*.txt", ...);
if (INVALID_HANDLE_VALUE != h)

No I just want to read in one copy of that file.

this files will be ream in over and over.
So I need to read in them ones and if there is
a new file like bla2.txt I need to read in that file to but NOT bla.txt and bla1.txt one again.

It sounds like you might benefit from ReadDirectoryChangesW() and/or FindFirstChangeNotification() instead.

NO!,
I need to check for *.txt files every second.
And when I find a *.txt file I need to read in the the information from that file. So I need a check so I don't read in the same file one again. I only need to read the file ones. So how can I do that?

How about using SetTimer(1000)?

Can you rename the file before it has been read?

I have been searching for a way to modify the time it takes for a sub menu to be displayed when the mouse hovers over the parent item. I know I can change this setting system wide using SystemParametersInfo(SPI_SETMENUSHOWDELAY, ...) but I would not like to make a system wide change, just application specific.
I believe I will need to subclass CMenu to change this default behavior, but I have been unable to find out where in CMenu the code that is doing this lives. Does anyone have any idea where/when this registry value is queried so that I can replace it with my own settings?

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

Thanks both.

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;
}

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?

you could use CCommandLineInfo::FileNothing as a parameter to ParseCommandLine

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 ?

Yariv

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!!
