Is "agsdfgggggg" a unique string? Is there some pattern? Does it always have the same number of characters?

If you give us a bit more information we may be able to give you better advice than CString::Left(6) for example.

Wow, I have no clue what you are talking about but the answer is probably liquid nitrogen[^]

Ok, serriously now. What does ReverseFind have to do with your question ? Why are you talking about words (I only see letters in your string) ? Is your string always "agsdfgggggg" and you always need to remove "gggggg" ? In which case, I don't see why you are asking the question D'Oh! | :doh:

Have you ever tried to use agsdf when it was next to gggggg? It's difficult at best.

Take a look at the MSDN pages for CString(). This class contains many useful functions, one of which will probably solve your problem.

What about

CString name = "agsdfgggggg";
int l = name.GetLength();

int count=0;

while (l-- > 0)
{
  if ( name[l] != 'g') break;
  count++;
}

if ( count > 0 )
{
  name = name.Left(name.GetLength() - count);
}

?

Let me restate your requirement.
You want the repeating character at the end to be removed.

If this requirement is correct, here is what you can do.

name = name.TrimRight(name[name.GetLength() - 1]);

Of course, you will need error checking, which I have omitted.

How to compare two HKEY handles

If I have two HKEY handles how could I compare them?

How could I get the full registry tree path of an open HKEY?

I could not find between the Reg... functions any one
which could help me to solve above two problems.

I assume you want to read the registry keys and compare them. There's tons of articles on how to read values from the registry.

no this is simple one and there are tone of articles.

What I want is to get what is behind the HKEY in therms of
path in the registyr tree.

For example If I open two HKEY to
HKEY_CLASSES_ROOT\*

How could I get from the HKEY handle this path:
HKEY_CLASSES_ROOT\*

And how could I compare the two HKEY handles to check
that they both are point to same path in the registry tree.

I think what Christian said is correct - you have to read the data (enumerate the keys and/or values) that each of your HKEY's point to to see if the paths etc are the same (ie by comparing the results of the enumeration) - since you dont 'know' where you are in the tree and likely cant make any assumptions, I think this is the safest bet ..

But with this proposal if there are two keys with same names/values
I should consider that both HKEY are the same.

This is very recursive solution which could take time to compare
each name/value of the sub keys.

Any other ideas?

Interesting: how did you fit the C language inside the .NET framework?

You should build an application that uses the library, possibly stressing it a lot.

You mean the size in bytes of a double ?
If yes, use the sizeof operator:
int lenght = sizeof(double);
