I tried to use ::ExitWindowsEx(EWX_POWEROFF, 0) but it did not shut down the pc, instead, it logs off the current user. On Win2000/XP it worked properly though.

Hi,
I utilize Visual C++ 6.0 and MFC for many years.
I want to know a few suggestions of books to do a transition toward Visual Studio. NET, preferably C++.
I don't need web development now. I have remark that many books about Visual Studio.NET include web development. I am looking for a bok specifically for Visual C++ in the .NET IDE.
Thanks for any suggestions,
Claude

You need to write a device driver for that. There should be several free ones on the net that already do the work for you.

We had some success using winio from http://www.internals.com/[^] last time we were doing this at uni.

hi:
I want to read the CD_ROM MODE2 sectros,but I don't know what's wrong with the code.The "Result" is TRUE and "error" is 0,but there is no data in the "lpSector".
who can help me.
thank you very much
hCD = CreateFile ("\\\\.\\M:", GENERIC_READ,
FILE_SHARE_READ|FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
NULL);
RAW_READ_INFO raw_info;
ZeroMemory(&raw_info,sizeof(raw_info));
raw_info.DiskOffset.QuadPart =2000*2352 ;
raw_info.SectorCount = 10;
raw_info.TrackMode = YellowMode2;
Result=DeviceIoControl(hCD, IOCTL_CDROM_RAW_READ,
&raw_info, sizeof(RAW_READ_INFO),
lpSector, dwSize,
&dwNotUsed, NULL);
DWORD error=GetLastError();
WriteFile (hFile, lpSector, dwSize, &dwNotUsed, NULL);

How about ReadFile() instead of WriteFile()?
John
|
|
|
|
|
Using ReadFile can't read CD_ROM MODE2 FORM2,
First all ,thank you very much
|
|
|
|

I am a little confused. You can not expect to read anything with a WriteFile()?
[EDIT]
Oh... I see you are trying to do the read with DeviceIoControl.. I got confused by the WriteFile part..
[/EDIT]

Sorry for the confusion. I am not sure of the answer. And it looks like it will be a difficult question to find an answer as there are not too many hits when I search the net for IOCTL_CDROM_RAW_READ.

I want to do another thing with WriteFile,
I have used ReadFile,but it can read MODE1 and MODE2 FORM1,can't read MODE2 FORM2.
So I want to read MODE2 with DeviceIOContrl and IOCTL_CDROM_RAW_READ
but there is no data in the buffer

I am trying to constrain the resizing of a MDIChildWnd to maintain a given aspect ratio. I am having no luck. The best I have been able to do is in the CWnd::OnSize function to look at the new size, calculate what a properly proportioned frame should be and call CWnd::SetWindowPos. I almost get what I need, it is just there is no frame around the client area. Annyone have any ideas?

Take a look at CWnd::OnSizing and CWnd::CalcWindowRect

I'm having some trouble with static members in my program. This is what my code looks like:
<br />
#ifndef TIMER_H<br />
#define TIMER_H<br />
class Timer<br />
{<br />
private:<br />
static LARGE_INTEGER m_lTicksPerSecond;<br />
static LARGE_INTEGER m_lTime;<br />
static LARGE_INTEGER m_lFirstTime;<br />
Timer();<br />
public:<br />
static bool Initialize()<br />
{<br />
if(QueryPerformanceFrequency(&m_lTicksPerSecond) && QueryPerformanceCounter(&m_lFirstTime))<br />
return true;<br />
return false;<br />
}<br />
static double MsSinceStart()<br />
{<br />
QueryPerformanceCounter(&m_lTime);<br />
return ((double)(m_lTime.QuadPart - m_lFirstTime.QuadPart ) / (double)m_lTicksPerSecond.QuadPart ) * 1000.0;<br />
}<br />
};<br />
#endif<br />
Or you can check it out at http://www.rafb.net/paste/results/SD400728.html (don't know if codeproject supports the formating).
Anyway, the error I'm geting is:
error LNK2001: unresolved external symbol "private: static union _LARGE_INTEGER Timer::m_lFirstTime" (?m_lFirstTime@Timer@@0T_LARGE_INTEGER@@A) on every member. The program it self is a win32 application.
Grateful for any help

You should define all static members in the timer.cpp file, e.g.
LARGE_INTEGER Timer::m_lTime;.

I'm sorry but I can't get it to work :/
When I place LARGE_INTEGER Timer::m_lTime etc inside my .cpp file it begins to talk about redefinition errors.
If I remove LARGE_INTEGER m_lTime etc from my .h file it says 'm_lTime' : is not a member of 'Timer'.
could you write just a simple class with a static member explaining it to me?
|

Did you define m_lTicksPerSecond, m_lTime,m_lFirstTime and in your cpp file.
LARGE_INTEGER Timer::m_lTicksPerSecond=0;
LARGE_INTEGER Timer::m_lTime=0;
LARGE_INTEGER Timer::m_lFirstTime=0;
Also have you checked out this:
http://www.naughter.com/cputicker.html[^]
Removing the mfc part only takes a few seconds...

oki, I checked out the cputicker class but still can't figure out what I'm doing wrong, perhaps I'm geting blind to my code.
This is what my 2 files looks like now:
Timer.h
<br />
#ifndef TIMER_H<br />
#define TIMER_H<br />
class Timer<br />
{<br />
protected:<br />
static LARGE_INTEGER m_lTicksPerSecond;<br />
static LARGE_INTEGER m_lTime;<br />
static LARGE_INTEGER m_lFirstTime;<br />
Timer();<br />
public:<br />
static bool Initialize();<br />
static double MsSinceStart();<br />
};<br />
#endif<br />
and this is what Timer.cpp looks like:
<br />
#include "Timer.h"<br />
<br />
LARGE_INTEGER Timer::m_lTicksPerSecond = NULL;<br />
LARGE_INTEGER Timer::m_lFirstTime = NULL;<br />
LARGE_INTEGER Timer::m_lTime = NULL;<br />
<br />
bool Timer::Initialize()<br />
{<br />
if(QueryPerformanceFrequency(&m_lTicksPerSecond) && QueryPerformanceCounter(&m_lFirstTime))<br />
return true;<br />
return false;<br />
}<br />
double Timer::MsSinceStart()<br />
{<br />
QueryPerformanceCounter(&m_lTime);<br />
return ((double)( m_lTime.QuadPart - m_lFirstTime.QuadPart ) / (double) m_lTicksPerSecond.QuadPart ) * 1000.0;<br />
}<br />
and this is the error which seems relevant: error C2039: 'm_lFirstTime' : is not a member of 'Timer' (which it as you see is)
hehe, plz bare with me
