I think that is a enough value. But let me ask you one thing,
how many number of records will be there for you in the average case and worst case.

if the 00:00 hour occur between two date-time variables, should the variables have different days, shouldn't them?

hi,

i have made a derived class from CDialog to customize it with my bitmaps in which some pixels need to be transparent. I am using TransparentBlt() for the same in OnEraseBkgnd() in derived class after calling CDialog::OnEraseBkgnd(). the thing is happening is those pixels are either coming grey so white sometime. not becoming transparent. Can anyone suggest where i am doing wrong !!!

thanx

hope you calls the CDialog::OnEraseBkgnd() before doing the TransparentBlt().

When you call the OnEraseBkgnd base method MFC calls the DefWndProc which will fill the dialog with its associated background brush, so remove this line.

Also, make sure to set the transparent style of the dialog to TRUE

How can I implement a schedule reboot prompts using WUAPI? Or some other way?

Hi, all there:

I was doing some stuff on windows update download&install using wuapi, and this done already.
Now I wanna implement a schedule reboot prompts, just like windows os do after auto windows update, which you can select "reboot after XX minites" or "reboot now".

Does anyone know how to implement this? Can WUAPI do this? Or some other way?

Any replay is appreciated!!

above.

Use InitiateSystemShutdownEx[^] function.

The process need to have the SeShutdownPrivilege() privilege to call this api. Check http://www.codersource.net/mfc_shutdown_timer.html[^] if you want to know, how to set this privilege.

why CCriticalSection::Lock doesn't allow to set the timeout

Ramon F. Mendes1-Nov-09 14:52

as far as I know, the only difference between CMutex and CCriticalSection is that CMutex works at the kernel level and so can be used across process boundaries

So why can you specify the timeout with CMutex::Lock method, but not in CCriticalSection::Lock?

CMutex mutex;
mutex.Lock( 1000 );

CCriticalSection critsec;
critsec.Lock( 1000 ); //here you will get an assertion

At the API level, you can use any of the Wait functions like WaitForSingleObject to wait on a mutex but not on a critical section. That is why the MFC wrappers work in a similar fashion.

For a mutex there is an associated handle.
But for a critical section there is not handle.
