Maybe, but you're testing will be the ultimate judge of that. Don't discount Superman's "respond to WM_QUERYENDSESSION rather than WM_ENDSESSION" suggestion.

Also ..If I want to distinguish betwwen a Shutdown event and a Restart event , what should be done in achieving the same ? As , WM_QUERYENDSESSION doesnot give me any differentiation between Shutdown and Restart. Is there a way to know specifically which one of the two has been initiated ??

That has been asked before, but I do not recall the answer. Have you looked at the lParam parameter?

I want to load a pdf file on the click of a button.
In the OnClickButton() implementation I am writing the function which open the PDF file
ShellExecute(0,
"Open",
"%s\\HELP\\RiverCADPro_User_Manual.pdf",
NULL,
NULL,
SW_MAXIMIZE);
The above code is not working.What else is to be needed so as to run the above code

What is this "%s" on the start of the file path??? 
I've tested the form below and it works fine:
ShellExecute(NULL,
_T("Open"),
_T("D:\\Test.pdf"),
NULL,
NULL,
SW_MAXIMIZE);

Thank You!!
Actually its a help file which I want to open on the click of help button.
Can you please tell me that how we are going to open the related bookmark.

Now i will give you an example code which works with Acrobat Reader. But you have to get the path to Acrobat Reader yourself and also form the command line parameters for your need. You can find information about the cmd line parameters of Acrobat Reader here[^].
Here is the example for you:
const CString strAcroPath = _T("C:\\Program Files\\Adobe\\Reader 9.0\\Reader\\AcroRd32.exe");
const CString strParameters = _T(" /A \"page=5&zoom=200&pagemode=bookmarks\" ");
const CString strFilePath = _T(" \"D:\\Test.pdf\" ");
const CString strCmdLine = strParameters + strFilePath;
ShellExecute(NULL,
_T("Open"),
strAcroPath,
strCmdLine,
NULL,
SW_MAXIMIZE);
The code above will work only on systems with Adobe Acrobat Reader installed!!!
If you want to support other readers you have to find information whether they support cmd line parameters and if yes then what is the exact syntax.
I hope this helps!

What does it mean, exactly?
Do you know ShellExecute has a return value?

Thanks Once again.
Actually I want to get the registry path where the .exe of Acrobat reader is.
So that I can pass the command line arguments to it ...........
Because to open a PDF with sppecific book mark I need the exe path and by command line argument I will pass the page number to it.
Like wise we do in Delphi
HelpFilePath : String;
DoesFileexists : Boolean;
CommandLine : String;
ExePath : String;
IsAcroExeLocated : Integer;
ButtonSelected : Boolean;
AcroVersion : String;
//Extracting Acrobat executable file path from Registry
// replace the double quotes and %1 from the string
ExePath := AnsiReplaceStr(GetRegistryValue('\AcroExch.Document\Shell\Open\Command'),'"','');
ExePath := AnsiReplaceStr(ExePath,'%1','');
// creating the help file path from WaterNET.exe path and file name
helpfilepath := extractfilepath(application.exename) + 'help\WaterNET_user_manual.pdf';
DoesFileexists := False;
DoesFileexists := Fileexists(ExePath);
if DoesFileexists then
begin
{ Display Alert message that Adobe Reader 5.0 Required }
//GetVersion finds the version information using the file properties
AcroVersion := GetVersion(ExePath);
if StrToIntDef(AcroVersion,0) < 6 then
begin
MessageBox(Application.Handle,
pchar(#13 + 'Adobe Acrobat PDF Reader version6.0 (or newer) is required.'),
pchar('Adobe Reader Version'),
mb_OK + mb_ICONWARNING + MB_APPLMODAL);
exit;
end; //if StrToIntDef(AcroVersion,0)
// Checking that specified file is existing
if Not FileExists(HelpFilePath) then
begin
MessageDlg(MSG_HELP_FILE_NOT_EXIST, mtWarning, [mbOK], 0);
Exit;
end;
// set command line parameters based from where the help file is opened
case BookmarkConstant of
WNET_HELP_USER_MANNUAL :
// when user clicks on help->user mannual
begin
// '/s' used for silently opening the acrobat reader instead of the splash screen
CommandLine := ('/s /n /A page=1 "'+ helpfilepath +'"');
end;
help_WaterNET :
// when user clicks help-> WaterNET Help or press F1
begin
// '/n' used for openning the file in same opened acrobat reader
CommandLine := ('/s /n /A zoom="100"&page=1&pagemode=bookmarks "'+ helpfilepath +'"');
end;
else
// when user click help button on a dialog
begin
// using '/A' all the parameters consider as a string
CommandLine := ('/s /n /A page='+ inttostr(BookmarkConstant) + '&View=FitBV "'+ helpfilepath +'"');
end;
end;
IsAcroExeLocated := 0;
//executing the Acrobat.exe with command line parameters
IsAcroExeLocated := ShellExecute(0, {Forms handle}
'open', {Operation}
PAnsiChar(ExePath), {EXE name with path}
PAnsiChar(CommandLine), {Commandline parameters}
nil, {Working directory}
SW_SHOWMAXIMIZED); {show
state}
end;
// checking if Acrobat reader is not available then go for download the Acrobat
if not (DoesFileexists) or (IsAcroExeLocated < 32) then
begin
buttonSelected := MessageBox(Application.Handle,
pchar(#13 + 'No Adobe Acrobat PDF Reader found. Press OK to download Adobe Acrobat Reader or press Cancel to abort.'),
pchar('Adobe Reader Required'),
mb_OKCANCEL + mb_ICONWARNING + MB_APPLMODAL) = IDOK;
// checking if OK button is pressed then open the link for download the Acrobat
if buttonSelected then
begin
ShellExecute(0, {Forms handle}
'open', {Operation}
PAnsiChar('http://get.adobe.com/reader/'), {EXE path}
nil, {Commandline parameters}
nil, {Working directory}
SW_SHOWMAXIMIZED); {show state}
end;
end;
But I want to do all in VC++

FindExecutable() should do what you require.

question remain, do you want to load that in Adobe reader or in your application itself

Here is my code:
vector<int> CPanoCylinderImage::RGBofPixel(CImage image, int x, int y)
{
vector<int> vect;
COLORREF cr = image.GetPixel(x, y);
BYTE r = GetRValue(cr);
BYTE g = GetGValue(cr);
BYTE b = GetBValue(cr);
vect.push_back((int)r);
vect.push_back((int)g);
vect.push_back((int)b);
return vect;
}
float CPanoCylinderImage::IntensityOfPixel(CImage image, int x, int y)
{
vector<int> vect = RGBofPixel(image, x, y);
return 0.30f * vect.at(0) + 0.59f * vect.at(1) + 0.11f * vect.at(2);
}
float CPanoCylinderImage::LuminanceDifference(CImage image1, CImage image2, int length)
{
float diff = 0.0;
float sum = 0.0;
float intensity = 0.0;
vector<float> vectImage1, vectImage2;
for(int i = 0; i < image1.GetHeight(); i++)
{
for(int j = image1.GetWidth() - length; j < image1.GetWidth(); j++)
{
intensity = IntensityOfPixel(image1, j, i);
vectImage1.push_back(intensity);
}
}
return ;
}
image1 and image2 have been loaded correctly.When I calculate intensity first time, I got the right RGB value and intensity value. But second time, I got Debug Assertion Failed when it run statement "COLORREF cr = image.GetPixel(x, y);", messagebox told me that
File: ...........\atlimage.h
Line: 1217
Expression: hBitmap == m_hBitmap
Anybody know what's happening?

Why don't you pass the CImage object by reference?

Thank u! U solved this problem. Can you tell me why I failed?

Well, I don't know, exactly. Anyway using a copy of the image object is wrong, you need to use the actual instance.

Use NetUseAdd() for this.

Thank you,
NetuseAdd() function need to link with netapi32.lib but I am unable to download that files.
I am using windowsXP as client and windows 2003 server as server.

You don't need to download anything. That file is already in your Visual Studio folder.

<br />
imageNew.ReleaseDC();
when i pass the 9177, 68 ,10566,635 these rectangular portion ..the output of image contains only black.
the whole area of images are black ...how to pass these rectagular portion ..??

That's wrong. you should use, for instance:
CRect rect(rectCopy);
rect.OffsetRect(-rectCopy.left, -rectCopy.top);
imageOriginal.BitBlt(imageNew.GetDC(), rect, rectCopy.TopLeft());

thank for your replay
CImage imageOriginal;
imageOriginal.Load(_T( "read.tif" ));
CRect rectCopy(9177,68, 10566, 635);
CImage imageNew;
imageNew.Create(rectCopy.Width(), rectCopy.Height(), imageOriginal.GetBPP());
CRect rect(rectCopy);
rect.OffsetRect(-rectCopy.left, -rectCopy.top);
imageOriginal.BitBlt(imageNew.GetDC(), rect, rectCopy.TopLeft());
imageNew.ReleaseDC();
imageNew.Save(_T("D://imgnew.jpg"));
still its showing the whole area of image is black
???
