It is not valid for HT (Hyper threading) machine, one processor multiple execution chain

Fine...I'll include logical processors in the list of processors

Hi,
I wonder why the plus sign + and the vertical lines which indicate the hierarchy of the tree control don't get displayed in my dialog and only the texts and images are displayed in a hierarchical tree.
Thanks in advance.

Hi
What would be the best way to convert a CString value of say "C-YOu01"
to a numerical value ?
i thought of using atoi, however this returns 0
Any idea would be much appreciated

 Well, what did you expect ? If you asked me to convert that string into a numeric value, I would say that I can't. Your computer did the same. How do you convert that into a number ??

Because you're not able to work with base 128.

I wonder and willing to know any number system which has its string representation that contain the characters like (C, -, Y) other than A-F. 
|
|
|
|
|
Any numeric system you want can actually have that representation. We only use A-F in hexa cause it makes it easier to have a human readable representation based on decimal, sort of. But when you want a random numeric base and want to represent it visually you use what's easier, character codes (1 character visual, making it easier to link it to a single digit, rather than the 1658th digit  and numeric representation for the computer).
But yeah, for the OPs request, that would certainly return 0.

Well, symbols A-F of hexadecimal base system have nothing special. You can use N distinct symbols (as well an ordering criterion) to represent digits in a N-base numeric system. For instance you can use, though it is unpractical, the {ON,OFF} pair as digits for the binary system.

What is your desired output for the above string? Numeric value 1? (because 01 is 1)
Your solution has to be simple, but then that would depend on how the string will look like (no. of digits and the pattern in which they appear in the string). If you are clear on that part, you can easily write a solution.

Something like:
std::string str = "C-YOu01";
int nVal = 0;
for (int x = 0; x < str.length(); x++)
{
int c = str[x] - 48;
nVal += c;
}
std::cout << nVal << std::endl;

Got the point. Hence
int nVal;
nVal = strlen("C-YOu01");
printf("%d\n");
is a valid alternative?

Well, since you're just summing up character codes, I assumed you was driven by the broad requirement of returning a number from the string, that way my own piece of code is a valid alternative.

Hello board,
There is a function that checks if a pointer is in valid memory space in MFC, I have used that before but now I forgot that and MSDN help is so crap and stupid that despite that I've tried many keywords it returns completely unrelated subject. No wonder MSN never can match google.
Can anybody give me the name of that function, please to check validity of a pointer.
Also is there any function that checks validity of a handle. When I use CloseHandle, in debug mode sometimes an exception occurs that says handle value is invalid. while I usually define handle value as INVALID_HANDLE_VALUE in the beginning and my expression is
<br />
if(m_hHandle != INVALID_HANDLE_VALUE)<br />
CloseHandle(m_hHandle);<br />
but exception occurs and the value of handle is other than
INVALID_HANDLE_VALUE
Thanks and have a nice day.

Why do you need such a function ? A much easier (and cleaner) solution is simply to set the pointer to NULL when you destroyed it. Then you simply check if it is NULL or not. Same with the HANDLE.
|
|
|
|
|
|
And what's the difference with what I suggested (meaning setting your pointer to NULL when you deleted it) ?
|
|
|
|
|
do you mean if I simply set pointer to null it frees memory no memory leak no resource leak ...??? so the what's the need for delete we can simply assign null to a pointer. can you refer me to a document, please?
|
|
|
|
|
No, you need to delete it and then you set it to NULL. What I meant is, once you set it to NULL, there's no need anymore to check if the pointer is valid: simply check it if it is NULL.
