From the Online-MSDN, search for swprintf:
[...]
int swprintf(
wchar_t (&buffer)[size],
size_t count,
const wchar_t *format [,
argument]...
); // C++ only
[...]
With
buffer = Storage location for output
count = Maximum number of characters to store in the Unicode version of this function.
format = Format-control string
argument = Optional arguments
Cheers,

Was this reply meant for me ?

Partially.
I seemed that you knew what the correct way to call swprintf was, but were unsure about "why" (mainly because you used the limit 50 without any explanation).
That might, however, be a misinterpretation - I am not a native speaker of English, and might have misunderstood your comment.
My reply just gave the prototype, so that both you and the OP might read it, if necessary.

As array size is 50, I used it, and I think its implicit.

Same here.

Which API system calls to create a folder on Vista.
Its not CreateDirectory, I have tried it using API Monitor.
May be some shell's API. Can anybody help?
Thanks.

Hi All,
If I place a button in a dialog box, my perception is that the button should be the part of my dialog class. But when I see my dialog box there is no Button object.
How can I access that Button object. I need that object because I want to enable and disable that button according to some condition.
I also want to attach toottip to that button.
Please let me know if further clarification is required.

You need to associate a variable with the button (how to do this depends of which IDE you are using). The variable type must be a CButton in order to access functionalities of your button.

Other way is....
CWnd *pWnd = GetDlgItem( IDC_BUTTON/* Ur Button ID */);
pWnd->EnableWindow( FALSE );//Disable the button
pWnd->EnableWindow( TRUE );//Enable the button

Dialog class will be based on dilaog template resource, button would be part of that resource.

Apart from method Cedric has suggested, you can use GetDlgItem function for accessing controls on dialog,too.
GetDlgItem(IDC_MYBUTTON)->EnableWindow(FALSE);

If u r using VC++
Put the button in the Dialog.
Right Click on it and select "add variable"
Select access type (public/private)
Select Variable type (CButton)
Give a variable name (ex: m_buttonHello)
Now in the source file (.cpp) for dialog class
write: m_buttonHello.EnableWindow(TRUE) or m_buttonHello.EnableWindow(FALSE)
wherever necessary
Cheers

Could you please share your code so that it would be easier to track down the issue ?

i am trying to pass a integer value to my thread
int i = 9;
int *k;
k = (int*)i;
AfxBeginThread(Test,k);
and then using it in my thread like this
UINT Test(LPVOID pParam)
{
time_test = *(static_cast<int*>(param));
}
time_test is declared globaly as integer variable.
but the line written in thread declaration is giving a debug error while running
please help me in this

Why would you provide the thread with an integer value only to assign it to a global variable that could read from the thread in the first place if the main thread had assign the desired value to it?
To get started the right way when learning multithreading, have a look at Joe Newcomer's excellent article here[^].
It will teach you the basics and prevent you from making common mistakes.

That's a mistake, you should do k = &i;.
If you need read-only access to the external parameter, use, something like the following code:
int i=9;
AfxBeginThread(Test, (LPVOID)i);
...
UINT Test(LPVOID pParam)
{
int iValue = (int) pParam;
}
On the other hand, if you need full access to the externa parameter, the code will be:
int i=9;
AfxBeginThread(Test, (LPVOID)&i);
...
UINT Test(LPVOID pParam)
{
int * piValue = (int*) pParam;
*piValue = 7;
}
Hope that helps.

NO.
Simply CString class overloads the (LPCTSTR) cast operator. See MSDN.

CString::Left returns a CString and CString overloads the operator LPCTSTR. See here[^]

Did you not read the documentation? CString::Left(int) will not return LPCTSTR value. What is that you exactly want to do?
devvvy wrote: Is CString really LPCTSTR?
No.

I think the question lies here:
"Be careful with this operator. If you change a CString object after you have obtained the character pointer, you may cause a reallocation of memory that invalidates the pointer."

I agree. But it's handy and hopefully prevents some guys to do things such
p=(char*)myString.GetBuffer(20); that may be even more dangerous.
