Gotcha Ryan, it makes a lot more sense now, thanks for that.

Thanks. Is there another way of doing this that is not so intensive as keep checking GetForegroundWindow()? Or do I definitely have to take the Windows hook DLL route?
Many thanks,
KB

A hook would probably be the best way to do it. You could do what you are doing - just don't do it constantly - wait for 10ms or so between checks. But I would recommend using a hook.

Hi !
I have an enumerated type with for instance 8 enumerations.
I would like to do a for() loop to go through each of the enumerations.
Is there a way to do it easily in C++, or do I have to use a for(int i=... ;... ;...) and cast the int into the enumerated type ?
Thanks !
Jerome

Unfortunately, a for loop like
enum day {Sun, Mon, Tue, Wed, Thu, Fri, Sat};
for ( day d = Sun; d <= Sat; d++)
...
will not work as you can't add 1 to d . Have you looked at Neville's suggestion.

I'm currently working on a videosurveillance software.
I have to display, as fast as possible, sequences of bitmaps, with
streching possibility.
I'm using VisualC++ 6.0, and I'm looking for someone who tried
different ways to display such images :
- drawdibdraw family functions
- strechdibits functions
- opengl texture mapping
- directx
- ... others ?
My goal is to find the FASTEST way to do it, whatever method.
Thanks

Anyone knows how to work with 24bit pictures?
For negative it's not a problem, I just subtract every RGB value from 0xFF and it will be fine. But let's say we want to do a gray calculation like so: (3*red + 4*green + 2*blue)/9 for each RGB pixel. Since I have to use 8bytes in calculations, I get in 2pixels and 2 extra bytes which will just be there.
mm0: RR GG BB RR GG BB RR GG
and the next sequance will be:
mm0: BB RR GG BB RR GG BB RR
You see my problem?
How can I still use MMX to do this in 24bit pics?
thanks

Hi I am using a drag and drop to install a license file. How can I take the dropped file and save it to the install directory of the software?
I used an environmental variable to get the directory path where the file needs to be saved eg:
char *ptr;
ptr = getenv("LM_LICENSE_FILE");
I can do it using dialogs, but I need an alternative way, please help urgently!!!

Hi, how to do it properly?

I just tried the code you posted and it works just fine...
The error must be something other in your code. Can you perhaps post the compiler/linker output?
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Yes, it worked fine for me too, at least for last 2 months.
but yesterday it stopped working. I checked that in DEBUG.
Unbelievable, now it is working, I changed nothing in the code, NOTHING,
it works
What is going on!!!

Ha,Ha.
I've had my share of random compiler errors in my early programming years as well.
But as I later find out, 9/10 times it was my fault, or there was an explanation (however obscure it may be).

But 1/10 errors of your code was because of the compiler.
but as I said, my program was working, and I got that error.
and later, it started working again. I do not think that was my fault.
thatnx.

Hello, what is the correct way to enumerate MCI devices?
I've found the following ways:
1) In System.ini, the [mci] key
2) In registry the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MediaResources\mci key
3) I'm not sure, but can one use the wDeviceID like an index?
Which is the correct way? Or even another way to do it? Do you know a sample?

_outp(0x64, 0xAD);

__asm mov al, 0xAD __asm out 0x64, al

Hi!
I have two ATL objects, A and B. object A can be create from a method of object B. the user of this COM, should not directly create A in its code, but get one from object B.
I don't know how to stop the user from creating A directly.
Any idea?

1. Don't supply a coclass for A in the IDL
2. Remove A from your object map in the main CPP file for the project
However, you will need to make sure that the interfaces that object A provides are declared in the library block of your IDL file, or it won't 'publish' the interfaces in the TLB/DLL.

Hi,
I have a SDI application and dont want to show it on the task bar. What is the best way in doing this?
|
|
|
|
|
Set the WS_EX_TOOLWINDOW style bit.
"Blessed are the peacemakers, for they shall be called sons of God." - Jesus
"You must be the change you wish to see in the world." - Mahatma Gandhi
|
|
|
|
|
Where in the code do I add the WS_EX_TOOLWINDOW bit?
And will this always prevent the application appearing on task bar?
Thanks
Neil

When the window is being created (probably be calling Create) include the WS_EX_TOOLWINDOW style and it will always hide the taskbar 'bar'.
Regards,
Brian Dela
IE 6 required: http://www.briandela.com[^] It works now.

I done the following:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style |= WS_EX_TOOLWINDOW;
if (!CFrameWnd::PreCreateWindow(cs))
return FALSE;
return TRUE;
}
but still the application appears in the task bar at the bottom of the screen.

Thanks for the links brian.
I had a look, but still dont see what I am doing wrong
In the OnCreate I changed the style, but still the same.
