I want to develop a program that runs as a scheduling program (on my webserver). I can do that by setting up a timer and frequently check the date/time to execute appropriate functions.

But I think that way is not good, it put more stress to the server. Is there any better way to do that? Does window send us date/time notification?

Please show me the way.

Why not just use AT, or its GUI equivalent? It comes with the OS!

Wow I'd never heard of AT - thanks. Of course I've heard of Cron in the Unix world.

AT is console program on WinXP and I assume W2K and NT4 and possibly other Windows platforms which lets you run commands/programs at specific times. Open a command prompt and type AT.

Oh, "Scheduled Task" tool of Windows is based on AT, isn't it? If not, is that tool equivalent AT?

ultimatly every program (even the part of OS) do the same thing as you expect.
they also check for the date and time frquently and compare the current time

is Windows Sheduler can help you?

But using a timer is not an exactly way, by ex : Starting a task when a new day starts. We can not check date/time every 1/1000s, it wastes the computer resources.
I don't know how to do, but it's very important for me.
Thanks you.

Dialog app and OnKeyDown()

Steve Messer13-May-03 21:06

13-May-03 21:06

I have an MFC dislog app. The dialog has nothing on it since everything is being drawn my GDI+. My nothing I mean no menu bar or anything just a blank dialog.

I am trying to capture virtual key presses such as VK_LEFT, VK_DOWN etc. Several odd things are happening.

If you create a simple MFC dialog app with the wizard it will have two default buttons, On and OK. Using the wizard you add a message handler for OnKeyDown(). Now if you try to capture any keypresses the app just sound a "bonk" sound and does nothing. If you delete two default buttons then the OnKeyDown will capture keypress like 'A' and 'a' but still not pressed like VK_LEFT.

Ugh...

Can anyone shed some light on the subject?

Thanks,

Steve

For virtual keys like VK_LEFT try ON_WM_SYSKEYDOWN() and OnSysKeyDown().

Hi,
1. Check File exists
CFileFind chkFileExistence;

if(chkFileExistence.FindFile(strFileName))
{
//File exists
}else{
//File does not exists
}

2. Creating Temporary File Name
You can use different methods to create a temporary file
name. My suggestion, try to create a file name with
Date & Time.

Hope this helps.

to check if a file exist you can use the shell function

BOOL PathFileExists(
    LPCTSTR pszPath
    );

it takes the file path and return 1 if it exist and 0 if not

for temporary files, there is the function

UINT GetTempFileName(
  LPCTSTR lpPathName,      // directory name
  LPCTSTR lpPrefixString,  // file name prefix, first three letters is taken only
  UINT uUnique,            // integer
  LPTSTR lpTempFileName    // file name buffer
);

which can be used to generate temporary file names.

The temporary path is formed like this
lpPathName+'\'+lpPrefixString+[uUnique as hexadecimal] + ".tmp"
and returned in the lpTempFileName for e.g if the path is c:\ and the unique integer is 10 and the prefix is "fil" the result will be c:\fil000A.tmp.

The uUnique parameter should have a unique integer value but if you passed 0 the system will assign this unique value.

You can use _access() or CFile::GetStatus().

Here's how you check if file exists :

CFileFind fileCheckExistance;
CString strPath = "C:\\Test\\myfile.exe";

if ( fileCheckExistance.FindFile( strPath ) )
AfxMessageBox("File exists !");
else
AfxMessageBox("File doesnt exist.");

thanks to see my question

I hope to use MFC to browse remote directory
my ideal is write one server, one client

when client ask server`s directory
i let server transfer local "BROWSEINFO" to client
and client use it borwse directory function to read
server`s "BROWSEINFO"

but i can`t use socket to transfer "BROWSEINFO" ?
i don`t know what type "BROWSEINFO" is.

or what I think is total worng?

thanks~

edit control properties

13-May-03 14:47

Hello...I have a form with some edit controls. there are two modes (1 and 2). In mode 1 some controls should be available for editing, and a button visible and available; and other controls should be unavailable for editing and another button not visible.

Changing to mode 2 invert the availability.

My problem is that I do not know if this is possible to do it at runtime. If this is possible, how do I do it?

I know where to put the code to enable and unenable the controls, but I would like to know what are the visual c++ statements to do this.

Can anyone give me a hand?
Thanks

MDI Splitter Window crashes

User 665813-May-03 12:34

User 6658

13-May-03 12:34

Hi
I created an MDI application and divided the document into 2 rows, whereby the upper row is divided again into 2 colums (similiar to the irc-client mIRC).
The second row is of type CEditView, the right column of type CListView. That's how I created the splitter windows:

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) 
{
	CRect cr; 
	GetClientRect(&cr);

	if(!m_mainSplitter.CreateStatic(this, 2, 1)) 
	{ 
		MessageBox( "Error setting up splitter frames!", "Init Error!", MB_OK | MB_ICONERROR); 
		return FALSE; 
	}

	if(!m_mainSplitter.CreateView(1, 0, RUNTIME_CLASS(CEditView), CSize(cr.Width(), cr.Height()-iEditHeight), pContext)) 
	{ 
		MessageBox( "Error setting up splitter frames!", "Init Error!", MB_OK | MB_ICONERROR);
		return FALSE; 
	}

	if(!m_secSplitter.CreateStatic(&m_mainSplitter, 1,2,WS_CHILD | WS_VISIBLE | WS_BORDER, m_mainSplitter.IdFromRowCol(0, 0)))
	{ 
		MessageBox( "Error setting up splitter frames!", "Init Error!", MB_OK | MB_ICONERROR); 
		return FALSE; 
	}

/// OUTPUT
	if(!m_secSplitter.CreateView(0, 0, RUNTIME_CLASS(CFoxIRCView), CSize(cr.Width()-150, cr.Height()-iEditHeight), pContext)) 
	{ 
		MessageBox( "Error setting up splitter frames!", "Init Error!", MB_OK | MB_ICONERROR);
		return FALSE; 
	}

/// NICKLISTE
	if(!m_secSplitter.CreateView(0, 1, RUNTIME_CLASS(CListView), CSize(150, cr.Height()-iEditHeight), pContext)) 
	{ 
		MessageBox( "Error setting up splitter frames!", "Init Error!", MB_OK | MB_ICONERROR);
		return FALSE; 
	}

	m_mainSplitter.SetRowInfo(0, cr.Height()-iEditHeight, 0);
	m_secSplitter.SetColumnInfo(0,cr.Width()-iListWidth,0);
	m_secSplitter.SetColumnInfo(1,iListWidth,0);

	m_pOutputView	= (CFoxIRCView*)m_secSplitter.GetPane(0,0);
	m_pNicklistView = (CListView*)m_secSplitter.GetPane(0,1);
	m_pCommandView	= (CEditView*)m_mainSplitter.GetPane(1,0);

	CRichEditCtrl&	m_ctlOutput   = m_pOutputView->GetRichEditCtrl();
	CListCtrl&		m_ctlNicklist = m_pNicklistView->GetListCtrl();
	CEdit&			m_ctlCommand  = m_pCommandView->GetEditCtrl();

...
}

But whenever I hit Ctrl+X/C/V inside the EditView or the ListView my app crashes in viewrich.cpp in line 1870:

COleClientItem* CRichEditDoc::GetPrimarySelectedItem(CView* pView)
{
	ASSERT(pView->IsKindOf(RUNTIME_CLASS(CRichEditView)));
	return ((CRichEditView*)pView)->GetSelectedItem();
}

Where's the error?

Thanks in advance
Greg

the basic problem is MFC command routing not going down into the individual views inside mdichildframe, so either fix that

CFrameWnd::OnCmdMsg()

ie cut, paste ,copy is not being handled by each individual view but by either the document or the app.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
