Unless there is a compiler bug (very unlikely) you have a bug in your code that only shows up with optimizations on. Likely this is some kind of memory allocation bug. Impossible to say without seeing your code.

Hi,
I cannot get VS2005 to work properly on my Vista when I use the dialog app wizard, nothing happens - I have the Sp1 update etc installed for VS. Can someone tell me if there is a workaround for me to get the files the wizard would create, including a blank resource template that I can visually drag and drop controls onto, and if there are still any issues with linking controls to code as I've seen before (I've not had VS installed for ages, and only previously on XP). Would these issues go away on an XP based system.
thanks for any help
cheers

Hi all,
This only happens on the release version of my project and it does not happen on the debug version. Also I have the same additional dependencies.

Did you forget to add them in the release settings ? Remember that you have to add them both for the debug version and the release version.

Hello,
I am currently writing a piece of software that needs to know if it is still running on the same PC as it was installed, or if it has been moved or the hardware has changed.
At the moment, I use the PCs network card MAC address, which usually works fine, but fails when the user changes network cards. This can happen if users use docking-stations with seperate NICs, or USB WLAN adapters, so I'd like to not use the MAC address anymore for system identification.
So the question is: are there other suitable ways to uniquely determine a PC? Is there a description of the way Microsoft uses to identify a PC when activating XP or Vista, which seems to work quite well, even if I change my network card my Windows stays activated, only if I do major changes to my hardware like changing the motherboard I will have to reactivate.
So I'd like to do it a similar way. Any hints how I can do this?
Thanks alot,
Erik

You could try using the computer SID.
|
|
|
|
|
Some (but not all) processors have an ID number. (I seem to remember reading Intel processors had it, but not AMD). You could use the volume-serial number, but this will change if the user replaces the hard disk.
I got the impression that Microsoft looks at multiple sources of identification, and detects a change when a certain threshold of things have changed. This allows you to replace a couple of components without the application breaking.

This is part of the holy grail for copy protection - it doesn't exist.
MS gets the info from a bunch of hardware on your system and assigns points to each.
e.g.
- How much ram, what type ...
- Graphic card specs
- CPU specs
- Monitor specs
- NIC MAC
The items that are considered to be fairly consistant over the life of a machine receive more points than others e.g. MAC may have a higher point value than the amount of memory.
The license manager checks the current settings against the previous ones (not just the last) and looks at the difference in terms of 'points changed in x amount of time'. If too many points have changed it assumes you are running on a different machine.

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

Dear friends;
How i can set my current date(Y,M,D), to a file name in c++ (DOS)?
Such as "20081210.txt".
Thanks.

Like this
<code>
int main()
{
struct tm *t;
time_t lt;
time(& lt);
t = localtime(<);
}
</code><pre>
do not forget to include "time.h"

I ran across a project in VC 5.0 source that I could really use, but I don't have a compiler. Can someone compile this little command line tool for me and send me the binary?

Thanks!

guys, can you give me some idea on how to control video recorder using VC++ and MFC..
for example, there is a video recorder connected to the pc, i want to create an application that can make that recorder to play, stop, pause, record, rewind and forward..
How can i do this?? i really dont have any idea...
|
|
|
|
|
I believe the first question that arises here would be: HOW is the recorder connected to the PC?
> The problem with computers is that they do what you tell them to do and not what you want them to do. <
|
|
|
|
|
the only way i can think is by connecting it by USB.... or anything, just to be able to create the program..
|
|
|
|
|
To control any device you would need specifications of the protocols the device used to communicate with the PC.
> The problem with computers is that they do what you tell them to do and not what you want them to do. <
|
|
|
|
|
and is that dependent on the hardware?? i mean, for example, different brands have different specifications, and different way to access?? this is gonna be harder that i thought... waa..
|
|
|
|
|
Well, there are some standards like for USB connected storage devices, i'm not sure if there are such for controlling a video camera but i guess there could be, i mean, most cams give you the same possibilities, like play, rewind, stop, such, so why not have a standard for that, my cam could be controlled thorough firewire, maybe try looking into that to see if there are any docs around.

wow, thanks very much for this info.. ill try to research on that..
|
|
|
|
|
i read that, and its just the connection.. though originally its for MAC, theres also available for windows..
i stil dont have any idea on how to program this... hmm.
|
|
|
|
|
Well yes, firewire itself is an interface. Check out this link about firewire[^] and look at the Interface section, there's something called AV/C, that looks like something you'd use to control a camera.

thanks for the link.. im still on the process of figuring out how to program it.. though i have a very large idea, thanks to you.

Hi,
In my application, which have number of dialogs. In a dialog already created, I added a button control.
When I try to add event handler function for this button thru class wizard I got an error message:
"Error in updating files(s)(C:Documen.......\ModelOpen.cpp,C:Doc....\ModelOpen.h) for class "CModelOpen"."
I also checked that files,its not in Read Only. Then where is the problem?
Also I tried deleting and recreating the .NCB and .CLW files. But in vain.
Pls help me and provide me a solution.

did you try to add the handlers manually. There is no magic done by the editor apart from adding the code at the right place. You just need to figure out where and why
You need to google first, if you have "It's urgent please" mentioned in your question.

Thanks for your rply.
I didnt tried adding the event handler manually; I think it might work. But I want to know why it fails through class wizard. So I want to know what's the correction I have to do to make it work
