cheers for that. This has always been a pain for ages, but never bothered to figure out how to change the behaviour

My laptop (running Windows ME) has the ability to hibernate. However, hibernation seems to fail when certain programs are running (I suspect those that make use of system timers). I want to write a piece of code to automatically close a list of programs if they are running and then effectively cause the system to hibernate. I need some help on this - I suspect that I'll have to use something like EnumWindows() to see if the programs are running, but will this pick up those that have minimised windows, or those "dormant" in the taskbar ? Also, how do I issue the call to the system to hibernate ? Apologies for the naivity !!! Thanks in advance for any help offered ! (Using MSVC++ Ver 4.0 by the way !)

Well I'd upgrade to WinXP if possible. ME is crap. I've never had a problem with Hibernate not working on XP.
If that isn't possible I'm sure you'll find articles here on CP which enumerate processes. Also look at sysinternals.com
There is a Win API for the Hibernate stuff. Do a search on MSDN http://msdn.microsoft.com/default.aspx[^]

hi,

I also tried to create a WorkStation and bind Desktop to it then it allowed me the 80 desktop. But i need the specify number of desktop i can create
The error i get in both condition is Error:8 (Not enough storage is available to process this command. )

Is there a system-generated event when a file is sent to print could someone include sample code ?
If I could use a system hook to listen for IRP_MJ_WRITE (Parallel Device)maybe? Any help would be appreciated.
Thanks

Use FindFirstPrinterChangeNotification and related APIs - there's VB articles on my site that you should be able to change no bother

Hi,
I have an ActiveX tested OK. Now I have added a method taking a BSTR and BOOL parameters and returning void. The VC Code compiled and registered correctly. I inserted this activex in VB and when I tried to call the newly added method it gives an error "Wrong number of arguments or invalid assignment error". I don't have any clue on why this error as the Object Browser shows the method signature correctly as declared. And also I am passing the same type of parameters. Can any of you help me to solve this issue?
Thanks in Advance,
Ishwari

I'm developing a Win32 console app in VC++ 6.0 where I have coded a edit box which works fine... however running my console app on Windows 98, my app affects the speed of the computer.
I have tracked the problem down to my "main input loop" where my app wait for the user to press a key.
The main loop (very simple!) looks something like this :
BOOL bOK=TRUE;
int cKey;
while (bOK)
{
while (!_kbhit())
{
}
cKey = _getch();
}
So my question is : is there a "proper" way to wait for a input chars in a console app which does not slow down Windows 9x ?
Please help, thanks

I am not sure about what you mean with Win32 console app. Is it a Win32 application, or a console app ?
If you have the Win32 code, then just process the message loop and check for keyboard messages.
If not, I guess you can use getchar();.

As i wrote... It's a Win32 console app
Not a DOS app but a 32bit console application.
Edit : I tried to process the Windopw messages but since my console app does not have a Windows (HWND) handle, I can't do that ;(

Do the sleep() call. I have console-app based servers -- we do the same thing of a kbhit/getch loop to look for the shutdown keystroke.
With a sleep(100) this thread bears no impact on the process.... Thread priority is not a good way to do this, since the crux of the problem is that your thread is always awake and always processing.
Threads should not be wasting process time when they don't need to.

I used the Sleep method which worked !
Thanks guys

It has been a while since I've done anything like this but,
I don't think you need your _kbhit loop. _getch() will wait for a character to be pressed before executing the next statement.
This is the MSDN example
int ch;
_cputs( "Type 'Y' when finished typing keys: " );
do
{
ch = _getch();
ch = toupper( ch );
} while( ch != 'Y' );
_putch( ch );
_putch( '\r' );
_putch( '\n' );
}

Thanks... that seems to do the trick
However I need to do some processing in my _kbhit loop, but maybe I can find a workaround for this.
|
|

If you need to do some processing inside the loop, call Sleep( 1 ) at the end of each loop. That should prevent starving windows of cpu time.
n!

|
|
Thanks, the Sleep worked for me
|
|
|
|

I think _getch() has a built-in wait so you might try removing the call to _kbhit().

I needed some processing in the _kbhit loop but using Sleep in the loop solved the problem, thanks

a) you can lower the thread priority while you wait for input
b) a Sleep(20) won't hurt
c) you can *try* if MsgWaitForMultipleObjects "wakes" your thread when you input a kjey (I doubt that, though)

I simply added a Sleep which did the trick

Hi,
Is there any method, function or way... to convert from ISO-8601 Date Format (yyyy-mm-ddThh:mm:ss), to COleDateTime ?
I'm tempted to make my own sh*tty function... but reinventing the wheel it's not a good idea... ( at least reinvent a bad wheel ).
Thanks in advance, Greetings

BOOL ParseDateTime( LPCTSTR lpszDate, DWORD dwFlags = 0, LCID lcid = LANG_USER_DEFAULT );
throw( CMemoryException );
throw( COleException );
should do the job (see MSDN for more). This parses your string and sets the COleDateTime.

Dear all,
How to access a C# DLL function from a MFC app? Is it possible?
VikramS
|
|
|
|
|
Yes it is possible.
You can do this in two ways.
1. By adding the /CLR compiler option and after that you can use the "#using" keyword to get your dll into MFC. for ex. #using <mycsharpassembly.dll>
You can instantiate the class or type inside your c# dll and call the methods.
Also note that with this your application now compiles to IL instead of x86 code,so unless you intend to compile the entire app to .net, this is not required.
2. Through COM Interop.
By decorating the c# class with COM attributes(mostly GUID) and then using the regasm tool to register the C# dll. Now you got a proper COM component in .net and you can use this MFC like how you access normal COM components.
Cheers,
Kannan
