With RH values in the 80s and 90s, it's far from dry. Last week, the heat index was 110. Sweating in that temperature does no good as the air is already too saturated to absorb it.

Hi,

I am copying attachments into my PC. Where i am using IStream, this one directly saving attachments but those attachments are saved in only office 12 folder, how i can change the path.

code is:

LPSTREAM pStrmSrc = NULL, pStrmDest = NULL;
STATSTG StatInfo;
if (FAILED(hRes = lpAttach->OpenProperty(PR_ATTACH_DATA_BIN,
(LPIID)&IID_IStream,0,MAPI_MODIFY,(LPUNKNOWN *)&pStrmSrc)))
break;
if (FAILED(hRes = OpenStreamOnFile(MAPIAllocateBuffer,
MAPIFreeBuffer,STGM_CREATE | STGM_READWRITE,
pRows->aRow[i].lpProps[0].Value.lpszA,
NULL,&pStrmDest)))
break;

where pstrmsrc is source destination, pstrmdest is copying destination.
how can i specify my path in this

thanx in advance

Here is the solution in details:

There is a discrepancy with the actual function and the header file. That's Microsoft's mistake which due to be fixed.

Go to MAPIUtil.h where OpenStreamOnFile is declared. Change

__in LPCTSTR lpszFileName,
to

__in_opt LPCSTR lpszPrefix,

Use ASCII file name when calling OpenStreamOnFile

C++ interview question

Hi,

I was asked the below in an interview:-

What does the following code below do?

<br />
char nextChar();<br />
<br />
int main()<br />
{ <br />
    char ch;<br />
    ch = nextChar() != '\0';<br />
    std::cout << (int) ch;<br />
 <br />
   return 0;<br />
}<br />

I said it would not compile since there is no definition (only a declaration) of the function nextChar() but the answer was 0 or 1. I am not sure why and also how can you use the != operator outside a if or while statement (i.e. something that expects true or false ?

Thank you for any input.

nextChar() != '\0'

This part of the code actually "returns" something (true or false). You then assign the result of the comparison into the ch variable. true is usually 1 and false is 0. So, your character will contain either 0 or 1. If you try to ouptut as it is (so, without the casting to an integer), you will end up printing the character whose value is 0 or 1 (so, not printable character), that's why you need to cast it to an integer.

I guess that having a body for your function was not really important for the interview question: they simply have a function that returns a character...

Hi ya,

Thanks for your reply. Yes as you correctly said the answer is 0 or 1. I got confused because of the lack of function definition.

Can I ask how it is possible that you can use the != operator without being enclosed in a statement that expects true / false ? e.g. while() , if()

Thanks for any information.

Yes you should get a linker error, due to the missing function definition

You need to google first, if you have "It's urgent please" mentioned in your question.

Most interview questions just use code fragments, and you're supposed to assume functions exist in other libraries (that's generally spelled out in the interview).

Mind you, this is a very simple example question and probably meant as a warm up, not actually a real test. You should see the kinds of questions we ask in our interviews (although coding tests are only a small part of them).

There are three kinds of people in the world - those who can count and those who can't...

Your point is correct (please note, however, that you would get a linker error, not a compiler one).

Now suppose nextChar is defined, somewhere (it's actual implementation doesn't matter).

minkowski wrote:

nextChar() != '\0';

the above expression evaluates true whenever nextChar return a value different from '\0', false otherwise. Since true is 1 [^] (false is 0) an implicit cast from bool to char (that is an integer type) happens and you get ch=1 (or ch=0).

That's the reason geometry is soooo difficult to grasp: triangle => three sides...while plain common sense would suggest triangle => three angles, or, at least, triside => three sides. Unsure | :~
