A simple linked list. Do something with the first, then move the first to the end (don't forget to update the pointers). Repeat to achieve round robin. Three words aren't going to get you any code - be specific and understand that this is not RentACoder; chances are you'll get helpful hints, not complete solutions

How to let an SDI-Appliction automatically scroll to present the last line of very long text in the output?the class used hier is CEditView.
|
|
|
|
|
Use CEditView::GetEditCtrl to get a reference to the edit control in the form of a CEdit class instance. Then you will need CEdit::GetLineCount, CEdit::LineScroll and CEdit::SetSel to perform the actual scrolling.

Hallo and thanks for the reply , i have this code in the Tes_Doc.cpp
CEdit &EditOutput = m_ptrOutput->GetEditCtrl ();// m_ptrOutput is CEditView Pointer
nLineCount = EditOutput.GetLineCount ();
EditOutput.LineScroll (nLineCount);
DWORD dwSel = EditOutput.GetSel();
EditOutput.SetSel (dwSel,true);
EditOutput.SetWindowTextA(m_strOutput);
The code does not work. I do not know why?
|
|
|
|

Try this sequence.
CEdit &EditOutput = m_ptrOutput->GetEditCtrl();
EditOutput.SetWindowTextA(m_strOutput);
LineCount = EditOutput.GetLineCount();
EditOutput.LineScroll (nLineCount);

 I have a program that uses MFC Dialog, GDI and DirectDraw to bounce a ball around a screen.
I have got it all working with 3 standard timers set at 1 ms 50 ms 1000 ms and a high performance timer.
I am using GDI to double buffer and bitblt and i am trying to use Directdraw to take this and avoid tearing by waiting for the vertical refresh.
My trouble is that as soon as you click on the screen it stops, It seems to be accessing the desktop somehow with the mouse.
Anyone got any ideas

The WRR algorithm is based on the Round Robin
algorithm but it takes into account the processing
capacity of each waiter.
• The administrators manually assign a coefficient of
performance to each waiter. ( 1, 2 and 3 in the example).
Counter

VCC 1 (Source 1) 1 1 1 Cycle
VCC 2 (Source 2) 2 2
VCC 3 (Source 3) 3 3 3 3 3

3
3 3 1 3 2 1 3 3 1 3 2 1

Coefficients of performance
….
• A sequence of scheduling is generated automatically
according to this value.
• The requests are then assigned to the various
waiters according to a sequence of alternate
repetition

Round-Robin algorithm equitably distributes
the load between each waiter whatever the
current number of connections or the response
times
RR
• This algorithm is adapted if the waiters of the
cluster have the same processing capacities
• if not, certain waiters are likely to receive
more requests than they can treat. Some
while others will use only part of their
resources.
• The WRR algorithm solves this problem.

I have this peace of code to choose a font family for the input text in ceditview class(i have here SDI_Appliction):
CFont *cfont = (CFont*) new CFont();
LOGFONT *lf = new LOGFONT();
m_cfdlg.GetCurrentFont(lf); // CFontDialog m_cfdlg;
strFaceName = m_cfdlg.GetFaceName();
nSize = (m_cfdlg.GetSize()/ 6);
cfont->CreateFont(nSize,lf->lfWidth,lf->lfEscapement,lf->lfOrientation,lf->lfWeight,lf->lfItalic,false,
0,1,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY, DEFAULT_PITCH | FF_SWISS,strFaceName);
CEditView m_ptrInput = (CEditView *) m_wndSplitter.GetPane(0,0);
ASSERT_VALID(m_ptrInput);
m_ptrInput->SetFont(cfont,true); // When this line apllied, the Text will have the size that benn choosen in the font dialog but not the font family or the face name ???
Any help would be appreciated.Thanks

Hello ,
My application needs to monitor all other running applications on the system. Is there some way I could get notified on exit of every application exe?
The methods I could find:
1) Use PSAPI functions to get the list of running exes at frequent intervals. At each poll compare with the previous list to find which application/process has exited.
Disadvantage: Requires constant polling, will take CPU time.
2) Set a global hook for WM_CLOSE message: Using this I would be able to get a notification when any application gets closed through the close button on the title bar
Disadvantage:
(-) Not all the applications are generating a WM_CLOSE message (Ex: Total Video Player Exe)
(-) If the application was closed through the "Exit" menu or button (e.g. File->Exit) , I can't trap that message
Is there any other better way that I missed? Please advise.

Why don't you capture WM_QUIT instead? This is the only message that finally halts the Message Loop.
But, you won't be able to track abnormal termination of an application with this.

But our application needs to handle that case too.

You will need to hook APIs like TerminateProcess in addition to installing a message hook.

3) Use WMI, as shown in this message[^]. The sample code is VBScript (and would need to be rewritten as below), but it works well enough.
' Get a reference to the WMI service
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
' Open a WMI query for __instancedeletionevents where the target instance is a Win32_Process
Set colMonitoredProcesses = objWMIService. _
ExecNotificationQuery("select * from __instancedeletionevent " & _
"within 1 where TargetInstance isa 'Win32_Process'")
' This call will complete the next time a process is deleted.
colMonitoredProcesses.NextEvent

Does this required WMI service running in the machine.
If it is turned off , will i able to catch this event "__InstanceCreationEvent"
Thanks

Yes, if you want your application to be capable of monitoring process creation/termination and also not rely on any Microsoft services then you will need to implement your own device driver. Typically anti-virus and other types of security products are using PsSetCreateProcessNotifyRoutine[^] to be notified of process creation and termination. An example of its usage is available here on codeproject:
Detecting Windows NT/2K process execution[^]

Hello,
I am also looking for a similar solution. My Questions are:
1) The solution requires DDK to be installed. Where can I download DDK from ?
2) Will this solution work on Vista ?
Thanks.

Hello there.
Identity Undisclosed wrote: 1) The solution requires DDK to be installed. Where can I download DDK from ?
The marketing people over at Microsoft change the name of their products every few years which really drives me crazy. The Microsoft DDK is now called WDK (Windows Driver Kit[^]) and the Download Kits and Tools[^] page will eventually bring you to the direct download link.
Identity Undisclosed wrote: 2) Will this solution work on Vista ?
Yes the PsSetCreateProcessNotifyRoutine [^] callback is avilable for Windows Vista and the driver will function correctly. However, Vista is very strict about loading unsigned drivers. You will need to sign the driver in order for Vista to load it. Below are some methods to get around the issue during the development phase:
Installing an Unsigned Driver during Development and Test[^]
TESTSIGNING Boot Configuration Option[^]

I don't know if this is possible, but I'd explore the possibility of getting a list of running exes. Duplicate their handle. Wait on that handle.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.
