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?

Hi All,
How do test dll which is created in C.
I have created dll using .NET FRAMEWORK in C programming.I want to test my dll as well as Unit testing.How do i do that.Please gimme any idea...
Thanks,

You need to create a test program that will use your dll...

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.

Did you use .NET IDE for develop native dll?

Hi All
Can i get double length?I have a variable double l=111.98987744,so can i get
l length
Plz help me.
|
|
|
|
|
You mean the size in bytes of a double ?
If yes, use the sizeof operator:
int lenght = sizeof(double);
|
|
|
|
|
Thanks for reply.
i use your code.It's return always 8.
double tr=111.989877445678;
int lenght = sizeof(tr);
result is length=8;
|
|
|
|
|
Yes, that's the size of a double.
Errr.. wait, you make me wonder. Are you asking for the lenght of the string representing the double ? If yes, there's no way to know that with precision because of the floating point precision. For instance, if you store 1 in a double, its value won't be exactly 1, but maybe 1.00000000001. So, it's not what you expect.
Anyway, why do you want know something like that ? It doesn't make a lot of sense... If you want to convert your double to a string, you can always specify the precision you want to keep.

you can always specify the precision you want to keep
yes i am converting double to Cstring(CSting str.formate("%.4f",double)).
But i want to convert same values like if double tr=98.29982355 then i want to convert Cstring str=98.29982355 and when tr=9.89 then str=9.89.
So i think if i have a length of double then it's make to easy.
Any way there is any more option to convert double to CString.
Plz help me

Well, but that's what I was explaining: tr=98.29982355, in that specific case, it is very probable that your double will be stored with some imprecision (for instance tr=98.299823499999999). There's no way for the computer to guess which precision you want to keep, that's up to you to tell to the computer where the number should be rounded when converting to string. I suggest you read this article[^] about floating point precision.

Why don't you use str.Format("%f", d) then?

Hello everybody,
what happend if i give codes in between #if 0 and #endif, will these line executed or not?
Thanks & Regards,
A. Gopinath.
|

Those code will not be compiled. So will never appear in the executable you build.
|
|
|
|
|
Such code is removed by the preprocessor, hence the compiler won't see it and the chances it will be ever executed looks very little...

Let us say i have a number of printf commands and strings in my code
eg printf("Hi"),printf("Hello") and other strings
Are all these strings stored in a string table automatically?
|
|
|
|
|
No. Those strings are not stored in the string table. I guess such strings are stored in the .rdata section of the binary where as the string table and its strings are stored in the .rsrc section of the binary file.

This (almost) exact same question was posted yesterday.

And I've a vague memory of it beign posted a couple of days before.
Are you both in the same class? Bidding for the same project!
