Re: How to restart a service every 3 hrs or reboot Windows every 3 hours

Configure the service to automatically restart in the Recovery tab of the Service Properties.

Then use a TimerQueueTimer set to 3 hours and have the Service Stop itself and exit normally when the timer event fires.

i don't want to method of retsrting service but i know the method of restrating machine.

you set WM_TIMER message of 5 min
eg
SetTimer(1,1000*300,NULL);//setimer for 5 min
and now make variable that increment after every WM_TIMER message
nCount++;//like this way
when timer equal to 35

use this code for restart
HANDLE hToken; // handle to process token
TOKEN_PRIVILEGES tkp; // pointer to token structure

OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken) ;

// Get the LUID for shutdown privilege.

LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,
&tkp.Privileges[0].Luid);

tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

// Get shutdown privilege for this process.

AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
(PTOKEN_PRIVILEGES) NULL, 0);

use
::InitiateSystemShutdown(NULL,ReturnStr,(DWORD)(atoi(this->m_nmpShutdown.Time)),TRUE,TRUE); this api's
thanks Smile | :)

I Think It will Work

check my application, about the simple windos utility. There I have designed a shutdown timer. you can configure it because you have the source code

Win32 Serial Communications

Is 115,200 Baud the max rate for Win32 serial driver? There are definitions for 128kbaud and 256 kbaud but these don't seem to work. If they did they would not work with the device i'm communicating with.

Thanks

They won't unless you have special hardware that supports them.
The highest standard baudrate is 115,200 baud and then that is divided to get 57,600 (/2), 38,400 (/3) etc.
It is possible they were put in place to support IDSN or something similar and never removed.

Removing title bar from CMiniDockFrameWnd

Ed Deighton21-Jun-04 8:24

21-Jun-04 8:24

Hi, I have coded a custom CMiniDockFrameWnd derived class that removes the WS_CAPTION bit from its style to remove the title bar from the toolbar in the app.

Only trouble is that that CDockContext class calls a static function in CMiniFrameWnd to calculate the drag rect of the bar. The function is defined as;

<br />
//afxwin.h<br />
static void PASCAL CalcBorders(LPRECT lpClientRect,<br />
	DWORD dwStyle = WS_THICKFRAME | WS_CAPTION, DWORD dwExStyle = 0);<br />
<br />
// winmini.cpp<br />
void PASCAL CMiniFrameWnd::CalcBorders(<br />
	LPRECT lpClientRect, DWORD dwStyle, DWORD dwExStyle)<br />
{<br />
	UNUSED_ALWAYS(dwExStyle);<br />
<br />
	AdjustWindowRectEx(lpClientRect, dwStyle, FALSE, WS_EX_PALETTEWINDOW);<br />
}<br />

Believe it or not, the CDockContext class uses the default parameters of the function so the drag rect of a tool bar is always calculated with a title bar and thickframe. This causes series bugs in my app not just a mis-aligned toolbar drag rect but the entire toolbar dragging screws up.

I was wondering if anyone knew a way to modify how CalcBorders behaives or how to modify the CDockContext::startDrag function without vast amounts of rewriting of MFC.

Building a neural network

21-Jun-04 9:05

Try handling the message yourself and cutting the framework out entirely. That part of MFC is known to be poorly written from an extensibility standpoint.

You want to spawn the OpenGL application, correct? One solution is CreateProcess().

I am very thankful for your suggestion. The first and foremost thing that I have to do is to open a bmp image when I use the open option on my interface in a seperate document (I mean window), but I am not getting how to write a process for any menu item (and where to define that process in my MFC program) that I create on the interface and I am also having 'save' and 'save as' options and I think I have to define processes for them also....but I don't know how to define them. But i have gone through 'CBitmap' functions but I am not getting how to define them in my MFC program so that I can display any bmp image when I use my open option on my interface.

Finding My Window State

21-Jun-04 7:50

I have a program which pops a window on an event, an incoming phone call. This bit of code works.

HWND temphwnd;
temphwnd = FindWindow(NULL,ProgramTitle);
ShowWindow(temphwnd,SW_RESTORE);

and I can minimize it when the call drops by.

ShowWindow(temphwnd,SW_MINIMIZE);

Can anyone tell me how I can find out the current state of my program window so that I can leave it in the same state as when the call came in. If the user has the window up and active I dont want to minimize it when the call drops.

21-Jun-04 10:32

OK Thanks for that so far Smile | :)

That gives me the Maximized/Minimized state in that it returns
SW_NORMAL if the window is maximized and SW_SHOWMINIMIZED if minimized. The next problem is, if the window is Maximized but behind another window how can I tell that and what call do I need to bring it to the front and make it active.

If I call ShowWindow(temphwnd,SW_RESTORE); that has no effect if the window is already Maximized but not active. The write up for SW_RESTORE says "Activates and displays the window" but this does not appear to work.

You may want to follow the ShowWindow() with a BringWindowToTop().

Take a look into using

    int X,
    int Y,
    int cx,
    int cy,
    UINT uFlags
