Me too!!! I actually suggested back when i was reviewing their book however still the same approach. I got to give to them #D is a really good iniciative including with some clever design with the Adding tree and all that however as you stated "Line quality is also not very good".
Yep, it is very hard to get open source up and running
Furthermore, I was really interrested in an Babel service as well for IL... ...I dont really have the time to code an entire Unmanaged by myself.
When I find a Babel service then we will be able to grow old together....;P

The templated Babel service is rather good. It took all of a few minute to make a code highlighter, mind you I never did figure out the yacc bit. But not to fear.
I'm busy writng a lexer/parser in C for uni (that will be ported of course) that is quite dynamic. It handles context free scanning as well grammer based parsing, and I have a nice idea to make a nice compiler interface for it. Also it uses a simplified flex/yacc notation. This will fit nicely in with the babel service.

Do you have any idea on how i could write a program which could search for any unwanted and unused entries in the registry?Target platform is Win XP. I just need an overview or strategy about how to design a program which could clean the registry.
Thanks.

hi, got a very straight forward question about Hashtable. Here's my C# code:
Hashtable users = new Hashtable(57);
users.Add("admin", "adminpwd");
users.Add("custofficer", "cust");
users.Add("branchmanager", "manager");
Console.WriteLine("passwd: {0}", users["admin"]);
I just want to do the same in C++:
Hashtable *users = new Hashtable(57);
users->Add(S"admin", S"adminpwd");
users->Add(S"custofficer", S"cust");
users->Add(S"branchmanager", S"manager");
//Error here: "...error C2143: syntax error : missing ';' before '.'"
String * passwd = users[S"admin"];
//"...error C2143: syntax error : missing ';' before '.'
Console.WriteLine("passwd: {0}", users["admin"]);
Any idea?

thanks for the feedback. but, it didn't work for some reason:
Hashtable* users;
users = new Hashtable(53);
users->Add(S"admin", S"admin");
users->Add(S"custofficer", S"custofficer");
users->Add(S"branchmanager", S"branchmanager");
//Compiler error here.
if(sPasswd==(String*) users->[sUser])
return "account number: 90210";
else
return "invalid password";

(String*) not allowed, use the proper casting technique.
users->[sUser] what happened to S"User"?

Now you are return unmanaged strings....
And lastly, try this: users->get_Item(S"User")

Hello, this is my first thread here. Mmmkay.
I'm not sure if i am right, but i assume that this forum is for C/C++ ? I compile most of my projects with LCC for win32.
So...What i am looking for but am unable to find ANYWHERE is some sort of 128-bit string encryption. Since i am developing a server application which holds some very sensitive settings which currently is for display if anyone decides to hexedit my application.
So...I want to encrypt these settings which currently are stored in strings as this: const char Password[] = "TEST";
Now you probably know what i mean when i say my current method is very, very insecure. I have searched the net for something that would encrypt my strings but i am very new into this and especially encrypting stuff (I just began growing interest for this stuff a month ago or so...)
Is there anyone out here who knows how i could encrypt strings and then decrypt the strings in WinMain ? So that it is usable by the application again....Please help it's very important and i will ofcourse give full credit for whoever decide to help me out...I'm getting rather desperate for something which would encrypt my settings...I don't like passwords and logins to be visible for anyone with a Hex editor...
Regards, and thanks in advance,
Micke Andersson

I don't have much experience with LCC, but I suppose you can call Win32 APIs from it. It that's the case, you probably can call CryptoAPI.
I hope that you have money because it’s necessary to be practical.
And I hope that at least once a year you put some money in front of you and say "you are mine" just to make clear who owns who. - Victor Hugo

I have a game in c# i'm making
A CPlayer is a
CGeneral is a
CPerson
ok so what if CGeneral and CPlayer need to implement the CEditableObject interface
do I use the override modifier in CPlayer so it overrides CGeneral or would I just do it as normal for both.
I think the first but would like a pointer on this to avoid confusion.

QUESTION 1. Can you pass custom defined object through COM interface? If you "Add Function" (right click classview on an ATL object/class), "Add Member Function Wizard" pops up. One can "choose" parameter type from the list of options available.
But what if I want to pass across interface the following:
a. A result set?
b. A user-defined class:
CMyClass
{
};
How can I do that? And can I do that in the first place?
QUESTION 2: What's the diff between "retval" and "out":
[propget, id(3), helpstring("property ComputerName")] HRESULT ComputerName([out, retval] BSTR* pVal);
"retval" IS "out" isn't it? If pVal is passed as a pointer, why do you need to marked the parameter as [out][retval]?
QUESTION 3: With ATL server projects, how can you add multiple interface? When you add "ATL simple object", the first interface is created for you by the wizard. Do you have do add to IDL file manually for subsequent interfaces? Is all that you need to do is to add to IDL? Any additional steps?
Thanks!

retval = return val. in the case of com its the return value of success. I havent done ATL programming in 6 months so bare with me. you return S_OK or S_FAIL. This is built in for com and should be either or. It indicates a pass or fail for the service host.
out is just return value you got that drill.

Well this one is an absolute pain and yes you will have mastered IDL by time you get this one down, i sure did. Add another simple object then add the interface instuctions to the main idl.
And dont forget depending on the clienbt accessing your com depends on the interface you inherit. Scripting versus the other<place the="" name="" i="" forgot="" here="">.
A great book that explains it in detail and in my opinion is invaluable to the ATL/COM programmer
by the way to pass an interface (CMyInterface **ppObject)
as you may know all interfaces are a pointer to a pointer
hope this helps. You might ask this in the ATL subject

I havent dealt with COM for almost a year - until recently, I built some stuff using ATL - that's simlpe enuf.
But now, I don't remember anything more than "interfaces are pointer to pointer", nevermind connection points,STA-MTA and all the rest =)
Lucky dot-net arrives. Remoting is rather easy to implement. If my job doesnt require that i code COM/ATL, i'd prefer not and spend more time on the recreational side of my life.
Thanks for feedback.

by the way if you havent done custom collections in ATL I would seriously by that book. It teaches them the best I've seen which was the sole reason I bought it but it was so good at explaining the core fundamentals of com I read it all the way through.
It also shows vb and c examples of using yoour object so you get a more vast understanding.

man, I am so sorry I goofed on retval
its the return value
like number = MyClass.Number;
retval is what is returned by number, sorry dude
{retval,out] is the returned type and [out] is just a pointer or whatever like buffer size on str functions
like [out] int *pVal is the pointer to your int you created before the call
int mine;
like number = MyClass.Number(&mine);
its been a while for c code but that should be right

humm... so, what is it. Return value is always S_OK/S_FAIL (HRESULT)??
[propget,id(3),helpstring("property ComputerName")] HRESULT ComputerName([out,retval] BSTR *pVal );
I my client code:
CCATLSimpleClass * pSysInfo = new CCATLSimpleClass;
try
{
//So, here, it's "return" value (and it did worked on my machine, by the way, what if there're more than one "retval"?):
String* sComputerName = pSysInfo->GetComputerNameA();
//Compile error: "...error C2660: 'pkATLSimpleASM::CCATLSimpleClass::GetComputerNameA' : function does not take 1 parameters"
pSysInfo->GetComputerNameA(sComputerName);
}
catch(Exception * e)
{
//.NET dont do HRESULT, return S_OK,E_MYERROR..etc will be packaged into an Exception object.
}
Checking dll with ILDASM,
instance string marshal( bstr) GetComputerNameA() runtime managed internalcall
Compare to source code, it seems tlbimp changes signature of the member function:
STDMETHODIMP CCATLSimple::GetComputerName(BSTR* sComputerName)
{
// TODO: Add your implementation code here
USES_CONVERSION;
if(!sComputerName)
return E_POINTER;
DWORD dwSize = MAX_COMPUTERNAME_LENGTH + 1;
TCHAR sTemp[MAX_COMPUTERNAME_LENGTH +1];
if(!::GetComputerName(sTemp, &dwSize) )
return E_FAIL;
* (sComputerName) = T2BSTR(sTemp);
return S_OK;
}
Now, what if there're more than one [out/retval]? Which one will be treated as "return"?
