I must concur with that.
I did some digging around, and there is talk that I can do a manual mage.exe to alter the project for click once.
Thanks

Does NSIS support 64bit systems? It doesn't seem like it in the project webpage...

That looks interesting. I never did like the click once deployment, but you can launch it from a web page.
Thanks Albert

Yes it does, I have been deploying 64-bit software with NSIS for the last 4 years. It is perfect for any kind of installation, worthwhile learning also.
I would suggest a special unicode branch of NSIS: http://www.scratchpaper.com/[^]

I'm using an outdated version of InstallShield which I absolutely hate... so I may have to try something else soon.

Hi everybody,
As you could read in my other question. I want to get rid of the CRL both external (/MT) or internal (/MD).
I am almost done and I eventually also want to remove the input of the msvcrt.lib. As soon as I do that I get an error on having _ftol2 etc not defined.
So I looked up my program in IDA and I noticed that they automatically generate _ftol2 and use it to convert from float to long.
Anybody knows how to get rid of these automatically generated functions.

yeah that will probably work. I will give it a shot.
EDIT: That worked flawless thanks!

Hi everybody,
I want to get rid of all the imports from the CLR. So I decided to make some functions on my own for example cos() sin() tan() asin() acos().
I already have cos and sin and tan done:
FLOAT Sin( FLOAT A )
{
_asm FLD A;
_asm FSIN;
}
FLOAT Cos( FLOAT A )
{
_asm FLD A;
_asm FCOS;
}
FLOAT Tan( FLOAT A )
{
_asm FLD A;
_asm FPTAN;
}
As you can see I am using inline floating point assembly. But then I thought I could probably use FACOS or FASIN, but those instructions don't exist.
Anybody know how I could constructe asin() and acos(), without using the CLR ofcourse.
Regards,
SystemFiles

when sine or cosine are known, so is the other (remember sin^2 + cos^2 = 1 ), hence also the tangent. Therefore use FPATAN.
|
|
|
|
|
takes a while before I understand what you mean hehe math actually isn't my best point of programming.
I will get to this later!
|
|
|
|
|
Sorry still dont exactly understand what your saying.
|
|
|
|
|
when you know cos, you know sin (except for its sign); and vice versa.
when you know cos and sin, you know tan. So use FPATAN.

Here's some old code that may help:
double Vk05Pi = 1.5707963267948966192313216916398;
#define MTH_ASM_IS0(LABEL_IS0) __asm \
{ \
__asm ftst \
__asm fnstsw ax \
__asm test ah, 40h \
__asm jne LABEL_IS0 \
}
#define MTH_ASM_IS1(LABEL_IS1) __asm \
{ \
__asm fld1 \
__asm fcomp \
__asm fnstsw ax \
__asm test ah, 40h \
__asm jne LABEL_IS1 \
}
double FkASinR( double A )
{
if( A > 1 ) return(0);
#ifndef MTH_ASM_USE
A *= A;
if( FkIs1(A, DBL_MIN) ) return(Vk05Pi);
return( atan( sqrt(A/(1-A)) ) );
#else
__asm {
fld A
fmul A
MTH_ASM_IS1(isone)
fld st(0)
fld1
fsubr
fdiv
fsqrt
fld1
fpatan
jmp end
isone:
fstp A
fld Vk05Pi
end:
fstp A
}
return(A);
#endif
}
double FkACosR( double A )
{
#ifndef MTH_ASM_USE
A *= A;
if( FkIs0(A, DBL_MIN) ) return(Vk05Pi);
return( atan( sqrt((1-A)/A) ) );
#else
__asm {
fld A
fmul A
MTH_ASM_IS0(iszero)
fld st(0)
fld1
fsubr
fdivr
fsqrt
fld1
fpatan
jmp end
iszero:
fstp A
fld Vk05Pi
end:
fstp A
}
return(A);
#endif
}
...cmk
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.

Hello people,
I was wondering of any good driver development/tutorial websites, books and source code I could "scan," (including source code of your own) cause I'm completely new to this and heard that driver are extremely powerful (especially in kernel-mode) and can do some neat things (firewalls)
Simple Thanks and Regards,

I think that's an over simplification, but if you are serious then start here[^] and be prepared for a lot of hard work.

You may also find that any driver specific questions will have a better chance of being seen by the specialists in this forum[^].

OSR[^] - These guys are the experts.
Check out their NT Insider articles.

as superman says, OSR, they do a free mag every two months, its very very good. Their website, osronline, is a must.
http://dumpanalysis.org/ is usefull for analysing dumps, something you are going to be doing a lot of.
Ndis.com is good for network stuff, like firewalls.
Most importantly you want to buy Walter Oneys book, programming the wdm, it is essential.

Nothing to say.

I'll learn that aswell.

Thank you, this could be very helpful in the future (including everything).
Do you suggest me working for a security company like Faronics (ever heard of Deep Freeze)?

Yes, it will give you a lot of experience. I have worked on similar products, and file system drivers, such as those used by Faronics to control applicaiton execution and so on are some of the most complex to write.

I am currently writing a game in C++ using OpenGL and I wonder which is the best way to deal with errors, once they occur (especially in games).
Note: I am currently using possibility 2, but I'm not really happy with it.
1. Exceptions - At first glance they seem to be the perfect for all kinds of errors, but I found out that exceptions can produce heck of a lot of overhead and extra time cost and IMO they're making the code ugly.
2. Return values - It's said that checking success using return values is deprecated since C++'s built-in exception handling. I can't share that opinion, but retrieving a return value and checking it doesn't seem to be an 'elegant' way of doing this and isn't beautiful as well (due to thousands of if and/or switch statements.
3. Return value + global error indicator - This one's really deprecated, even though I somehow liked the errno thingy in C
So, what do you use/what would you use and what would you recommend for my needs?
Thanks in advance.
PS: Do I have some kind of natural aversion to exceptions or are they really not the greatest invention since sliced bread?

I think in error handling, performance should not be of concern. So, the "I'm writing a game, everything must be fast!" argument doesn't work here. Errors should always be the exception!
Exceptions really help you to write smaller code. When using return values, you have to check them every time. If you forget to do so, you might miss an error. So they are really prone to bugs!
Exceptions on the other hand can't be simply ignored, and I think that's good.
