Is there any Date Time pickers that would allow you to modify both data and time within the same cell?

I have
p.CreateDispatch("DllwithForm.Class1");
p.CheckingPB(hPbWnd,0,100000);
where CheckingPB is triggering repeated messages to be sent to a control. If I uncomment the release dispatch , I am concerned that it will release the dispatch before all my messages have been sent and received. Is this a fact? Since the app isnt working anyways I cant check it out, but wondered if its disastrous if that line is commented out...
Thanks,

Help people, my head is spinning.....
I have an application that reads images back from a database into a directory. I need to 'touch' the file time stamp to match the database. The date field to retrieved as a COLEDATETIME and I need to convert this to a FILETIME in order to call the win32 SetFileTime() function.
Anyone any idea's how to perform this conversion (I'm sure is really obvious and the constructor for COLEDATATIME lets you do it the other way around!) --- Anyone any clues?

Use COleDateTime::GetAsSystemTime, then ::SystemTimeToFileTime.

hello,
Is it possible to have CreateDIBSection to allocate the bitmap in system memory rather than in video memory (without DDraw) ?
|
|
|
|
|
CreateDIBSection allocates bitmap data in 'system' memory, not in video memory.

The fourth parameter of CreateDIBSection (VOID **ppvBits) gives me values over 0x80000000, is it still system memory ?
|
|
|

|

It's just because I make memory access and they seem to be slow.
Never mind, I'll do more tests.
Thanks.

We delete an array of char this way:
delete[] str;<br />
str=NULL
But, if the string is created like str=_T("test"); or #define str _T("test"), trying to delete it results in an exception.
Now, my question is this: how can I figure out if the string is deletable or not? (must be a const prob)
I know I should strcpy those strings before use, but lazy me...

There's no portable way of determining if object is on the heap or not. Switch to std::string or CString and forget about it.

You can't.
Well, not without keeping some extra information anywhere.
Really this is a design problem, not an implementation problem - it's good practice to allocate and free memory at the same level of a program, so that level already knows how it allocated the memory.
For example
char* str = new char[100];
somefunction(str);
delete[] str;
char* str = "Hello world";
somefunction(str);
// No need to delete anything
The point is that "somefunction" didn't allocate the memory so it can't know how to free it and shouldn't try.
Basically whenever you allocate some memory you need to think about how it's going to be freed, and ensure that it's done at the same level as it was allocated, which is probably the only place that knows how to do it.

You may want to try with IsBadWritePtr. Do some experimentations with it to see how it handles strings (literal and dynamically-allocated strings).

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Or, just
try{ delete[] str; } catch(...){}

I used to code java like that! Does it work for c++ too?

Try
const LPCSTR str = _T("test");
and when the compiler complains about const do as it says. Don't cast the const away

I want to print a page which has predefined area, so that the printer prints the content which is in the defined area.Say for example, a document usually has 32x13 inches ruler. we predefine the size to 8x11 inches area of the document. we actually need to print the content of the 8x11 inches?
any help will be greatly appreciated. i desperately need this info. please send reply to vgkotha@rediffmail.com
thanks in advance,

Do you mean you want to print to a selected area of the page?
If you do, override the OnPrepareDC() function and modify the pInfo->m_rectDraw member var to limit the printable rectangle to your app to the area of interest.
You can do that by using something like:
pInfo->m_rectDraw.left = pDC->GetDeviceCaps(LOGICALPIXELSX) * inches_offset1 ;
pInfo->m_rectDraw.top = pDC->GetDeviceCaps(LOGICALPIXELSY) * inches_offset2 ;
And so on...

Hi all,
I use IDiskQuotaControl->FindUserName() and IDiskQuotaControl->AddUserName() to add quota entry to a network shared volume for every user.
But There are miss match of the function parameters between the Visual studio promotion and the search result of F1 help.
The Visual studio promotion after I type the funciton name and the "(" is:
///////////
HRESULT FindUserName(LPCWSTR pszDomain,
LPCWSTR pszName, PDISKQUOTA_USER **ppUser);
/////////
but when I search use F1 help:
the result is:
///////////////
HRESULT FindUserName(
LPCWSTR pszLogonName,
PDISKQUOTA_USER *ppUser
);
Then I tried the first function. compile and link ok but when execute to it, a Debug Error! occurce:
/**************
Debug Error!
Program: ***
Module:
FIle:i386\chkesp.c
Line: 42
The value of ESP was not properly saved across a funciton call. This is usually a result of calling a function declared with one calling convention with a funciton pointer declared with a different calling convention.
***************************
I suspect that the error was caused by the reson that there are two functions one is we used and can compile and link but the real function in some dll is the other one.
But when I use the second one in code, it can not be compiled. say the this funciton does not take two parameters.
And the same situation with the AddUserName()
Does any one know how to sovle this problem?
Thanks very much for your help.
Laura.
