Hello,
I want to put an image,like a logo, to the right of the main window of my application, just like Internet Explorer.
What is the best way to implement? (Using MFC)
Thanks in advance.

Hi,
I want to prevent the computer from sleeping while my program is working intensively. I found SetThreadExecutionState on MSDN[^]. But I'm confused what are the proper parameters.
Also, what parameters do I pass to the function when I don't need to prevent sleep anymore?
Here's the example from MSDN:
SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED | ES_AWAYMODE_REQUIRED);
SetThreadExecutionState(ES_CONTINUOUS);
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

The system prevents sleep mode by detecting user input.
It doesn't automatically detect processes using the CPU or the
display.
To tell the system you're using the CPU, use
ES_SYSTEM_REQUIRED
To tell the system you're using the display, use
ES_DISPLAY_REQUIRED
Of course, you can use combinations.
Use ES_CONTINUOUS to have your settings remain in effect until the next
call.
To clear your continuous settings, use
SetThreadExecutionState(ES_CONTINUOUS);

What about ES_AWAYMODE_REQUIRED ?
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Thanks for pointing that out. The example at MSDN had me confused with its using all the 3 params, but now I see it was about 'Television recording'

I am having two values one is of int type and another is of CString type.
Now I am calling SendMessage function as below:
m_ptrMainDlg->SendMessage(WM_CHAT_PICKED,m_nIndex,m_strSessionID);
but the above code is giving the following error:
Error 41 error C2664: 'CWnd::SendMessageW' : cannot convert parameter 3 from 'CString' to 'LPARAM' c:\documents and settings\shy\desktop\dheeraj latest working copy\sourcecodes 8-10-08(morning)\source code 06dec2007\popupdlg.cpp 148
Please tell me whats the problem
Thanks In Advance

Use this:
m_ptrMainDlg->SendMessage(WM_CHAT_PICKED,m_nIndex, (LPARAM) (LPCTSTR) m_strSessionID);
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

it is not advisable sending CString as sendmessage parameter, it always advisable to send Dyanmic allocated character pointer string!

Hi all,
In a FormView Derived class on OnInitialUpdate() function i m using a code that is use many function of my class when i vew this form than before opening the Mouse cursor takes much time and application looks like it hangs.
Can i use thread to reduce the time for open form view.(If yes Please tell me how can i use thread i have no idea about thread.)
or any other method.
please tell me.
Thanks in advance.

Yes, you can use a thread for that purpose. It won't speed up the time needed for the computation but at least your UI won't be frozen. Here's a link to a great article[^] about thread.

Hi everyone,
I want an application which detects mouse clicks on desktop (at a particular pixel on the desktop).
For this I have created a global mouse hook to detect mouse events but it detects mouse click on every window, how do i detect that the mouse has clicked on desktop.
thanx in advance
|
|
|
|
|
May be you can get the desktop window handle using
HWND hWndDesktop = GetDesktopWindow();
And compare it with the handle received in the HOOK procedure.
I hope it helps..
Regards,
Sandip.

By comparing the window handle with the desktop window handle. Convert the lParam to Mouse hook structure like
MOUSEHOOKSTRUCT *pMouseHooksStruct = (MOUSEHOOKSTRUCT *) lParam;
and use the hwnd member variable of the structure for which the event is generated for comparison.

Hello everyone,
In Windbg help document about poi operator, it is mentioned.
--------------------
poi
Pointer-sized data from the specified address. The pointer size is 32 bits or 64 bits. In kernel debugging, this size is based on the processor of the target computer. In user-mode debugging on an Itanium-based computer, this size is 32 bits or 64 bits, depending on the target application. Therefore, poi is the best operator to use if you want pointer-sized data.
--------------------
My confusion is, what means "pointer-sized data"? Does it mean something like the size of C++ pointer type variable, e.g. 4 bytes for x86 machine and 8 bytes for x64 machine?
thanks in advance,
George

Hi,
I have a Fortran program which I have to convert into Java originally. I have converted the code completely but can't get appropriate resutls. The code contains lot of arithmetic calculations using double precision data type of Fortran.
I believe the data types of C++ and Java are based on same whereas of Fortran double precision is based on IEEE756. I want to know how to convert these double precision calculations into C++ normally. For example:
double precision d1 = 0.3648564D0;
d1**2
DSIN(d1)
DCOS(d1)
The above are my main concerns which I find very difficult to convert. I use sin & cos for DSIN & DCOS. But Fortran 77 deals somthing differntly with double precision. How to convert/translate that into our normal C++ application is what I am looking for.
If you cna provide the same for Java that would be a plus for me, otherwise I will use the code accordingly of C++ in my Java application.
Please help me out. Am stuck up very badly.
Thanks
Terry

Do you mean IEEE-754? C++ do use IEEE-754 to store the floating point numbers. In fact the floating point number format are implemented at the hardware level and Intel processors use IEEE-754.

Never head about. Do you mean IEEE 754?

Even if the FORTRAN double precision would based on a different standard, I believe the results of both programs (i.e. the FORTRAN and the Java one) should be comparable. Are you sure the logic of your translation is correct?
Have you made a test to compare the results (given by FORTRAN vs Java) of such simple functions as sin and cos?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Is this safe?
inline void YieldMessages( int milliseconds, int sleepTime = 50 )
{
DWORD targetTime = GetTickCount()+milliseconds;
while ( GetTickCount() < targetTime )
{
AfxGetApp()->PumpMessage();
Sleep(sleepTime);
}
}
I wrote this when I was having trouble getting a CWinThread to shutdown. This let's me post a WM_QUIT and wait for the thread to terminte....
I've always wondered if it might be a hack...
