hello,
i'd like to convert rtf files into standard bitmap format, like bmp or jpeg.
the solution i have now is to open the rtf and print with a simulated windows
printed which generates a bitmap. but it would be good to find a direct solution,
maybe someone knows how to do this, or a product/library, which can do this?
thanks

I am using MS Word automation in my C++ project to create a Word document that contains several tables. I've been able to create the document and give it a specific format such as font sizes, paragrpah aligment...
My problem is that i am not capable of center a table. This is the code i use:
//get the range
oRange = oSelection.GetRange();
oTables = Doc.GetTables();
//try to center the paragraph where the table will be placed
oParagraphs=oRange.GetParagraphs();
oParagraphs.SetAlignment(1);
// Create a 5x5 table
oTable = oTables.Add(oRange,5,5,covTrue,covTrue);
But this doesn't seem to work, the table appears with left aligment.
Has anyone tried to center a table?
Thanks

Hi, everyone!
Look at the following codes,
--------
const char* p = "12345";
char* q = "54321";
--------
If I want to release the memory, should I use
--------
delete[] p;
delete[] q;
--------
or should I use
--------
delete p;
delete q;
--------
Thanks in advance,
George

You don't need to release the memory of these variables because they aren't allocated on heap but on stack. Defining char* q ="54321"; is the same as defining char q[6] = "54321"; .
You only need to use delete/delete [] for variables created with new/new [].

Rule of thumb: You did not call new , you do not need to call delete .
For
char* r = new char[MAX_PATH+1];
you would call
delete[] r;
since you did a new[] .
But this is one of the cases where it does not matter, since char is an integral type and as such has no constructor or destructor.
The difference between delete and delete[] is that delete[] calls the destructor of every item to be deleted, whereas delete calls only the destructor of the first item.
My opinions may have changed, but not the fact that I am right.

This is true on most, but not all compilers. According to the standard, new must be deleted, and new[] delete[]'d.
There is no guarantee that the compiler implements new[] "on top of" new. It could even use different heaps for that!

confused:hi all,
as we know..Internet Explorer stores information entered in the single fields of form when we submit it, so next time when you are filling the field with the same name, we are able to select value from dropdown list. I need a function that has field name as it's parameter and returns array of values stored in IE (so, I need to find where and how this information is being stored.) any help and any ideas are most welcome...
thanks in advance..

Hello!
Depending on your OS, but on NT the values are stored in the registry at
HKEY CURRENT USER\Software\Microsoft\Internet Explorer\IntelliForms\SPW
Unfortunally they are encrypted ...

Hi everybody,
For a CListCtrl with the report style, is there an easy way to prevent the user from resizing the column headers? I was hoping there would be a style setting for this, but I can't find it.
Thanks a lot.

I am not 100% sure about this, but you need to handle the HDN_BEGINDRAG message (?) and return FALSE. I seem to recall this from somewhere.
Hope its of help.

You need to handle the HDN_BEGINTRACK notification sent by the list's header control, and return TRUE to disable resizing.

If you implement a notification handler for HDN_BEGINTRACK and within that function set *pResult = TRUE, that will prevent the header sizing from happening. Unfortunately, the handler for HDN_DIVIDERDBLCLICK does not allow this override, so header sizing can still happen if the user double clicks a header divider. I don't know a way to change this behavior.

Hi,
I tried this, but nothing seems to happen. Resizing is still possible.
I just used the classwizard to add a handler for =HDN_BEGINTRACK and made the change you suggested, like this:
void CMyList::OnBegintrack(NMHDR* pNMHDR, LRESULT* pResult)
{
HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
*pResult = TRUE;
}
Perhaps there is something else I'm doing that's preventing your solution from working. But I can't find anything out of the ordinary. I just SubClassDlgItem() and set the extended style to include gridlines and fullrowselect.
Any ideas? Thanks.
Ren.

If you use classwizard to insert a handler for HDN_BEGINTRACK in the list control, it incorrectly inserts a reflection handler, even though the notification is sent directly to the list control (ie not through the reflection mechanism). That's why the classwizard handler is marked =HDN_BEGINTRACK (= indicates a reflected notification).
You need to replace the line ON_NOTIFY_REFLECT(HDN_ENDTRACK, OnEndtrack) in the message map with ON_NOTIFY(HDN_ENDTRACK, 0, OnEndtrack) . (See the MSDN knowledge base article Q281155)

Sorry guys, but it's still not working. I've tried changing the message map as directed, but nothing happens. The message is still not sent. (I've checked with a messagebox.)
I noticed that the MSDN article refers to CListView while I'm working with a CListCtrl. Could this have anything to do with it?

I have to admit I don't really understand everything being explained in the thread, but no worries: it works now.
I'll just give a short report for any interested parties too lazy to check the thread you mentioned:
PROBLEM: Stop CListCtrl column headers from being resized.
SOLUTION: Let your view handle the HDN_BEGINTRACK message and have it return TRUE.
void CMyList::OnBegintrack(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR; <br />
*pResult = TRUE;<br />
}
BUG: Something about the class wizard messing up and another thing about unicode and ansi, which results in your handler never being called.
FIX: Edit your message map manually.
First remove:
ON_NOTIFY_REFLECT(HDN_BEGINTRACK,OnBeginTrack)
And instead add:
ON_NOTIFY(HDN_BEGINTRACKW, 0, OnBegintrack)<br />
ON_NOTIFY(HDN_BEGINTRACKA, 0, OnBegintrack)
That's it. Thanks 4 the help, guys.
