your declaration gives you 8x8 values, not 9x9. your loops are spanning 9x9 values.

I see. Do you think the program would still run properly and give the correct values in the table/array if the loop was incorrect? Do you think that would cause the crash at the end? I will try mess with that coding.

there is no telling what you will get if you start writing off the end of an array. you could be writing into anything...

Remember that arrays in C/C++/C#/Java are indexed from 0 to size-1. So by reading the element at position 8, you're actually reading the 9th element. And your array only has room for 8.

you guys are awesome......that totally fixed it.

I knew that arrays started at 0 but i was sloppy in the coding and then didn't even think, since it worked properly, that the crash at the end was because of the loop...never entered my mind...

thanks a bunch..that fixed it....

Also don't use magic numbers, e.g. int array[8][8]
try #define MY_ARRAY_SIZE 8 (or const int MY_ARRAY_SIZE = 8)
array[MY_ARRAY_SIZE][MY_ARRAY_SIZE]

then, for(i = 0; i < MY_ARRAY_SIZE; i++)

Automaion question

I'm writing an MFC app that uses a word 200 object via automation. Of course this requires me to give the type library of word9 as well as word9 hearder files. Will this app work if I distribute it and the customers have a word version that is greater than 2000 such as Word XP or one lower such as Word 97? I don't have these office versions so anyone with MFC automation experience with Office , an answer would be greatly apprciated by me.

Thanks in advance,

Martin.

It depends what interfaces you use. We've had no trouble using apps built against Office97 and 2000 on systems with 97, 2000, and XP installed. But we stick to the functionality available in Office97.

(and of course, there's no guarantee that MS won't break compatibility at some point in the future... Wink | ;)

You look up the VC++ Help which tells you about: GetWindowsDirectory()

There would have to be a very, very good reason to use a function like BlockInput(). Surely you can simply test whether SendMessage etc. work. I would assume the will. The doc's don't indicate otherwise.

gina logon?

i am using msgina.dll feature of
Automatic Logon
This feature allows a Windows NT system to log on a user automatically every time the system boots, by using default information.
for this purpose i know the use of following registry keys

1-AutoAdminLogon
2-AutoLogonCount
3-DefaultUserName
4-DefaultDomainName
5-DefaultPassword

i am sucessfully using this when the system boot.
platform is window xp

but problem is that when i logoff(afterlogon) the window then the
Dialog box with title
------------------
LOG ON TO WINDOWS
-----------------
appears although the registery keys having values

AutoAdminLogon is 1.
AutoLogonCount is greater then 0 or did not present.
DefaultUserName is correct.
DefaultDomainName is correct.
DefaultPassword is correct.

what i have to do hear in code of gina dll so that
Windows NT system log on a user automatically against a perticuler SAS event(say ctr+alt+del or any other)?

How do I draw an X in a View?

10-Dec-02 8:41

I am trying to do something like this ...

CMyDoc::CMyDoc()
{
// TODO: add one-time construction code here
m_point = CPoint( 30, 30 );
m_upperLeft = CPoint( ??? something ??? , ??? something ??? );
m_lowerRight = CPoint( ??? something ???, ??? something ??? );

}

... and then do this ...

void CMyView::OnDraw(CDC* pDC)
{
CMyDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
pDC->MoveTo( pDoc->m_upperLeft.x, pDoc->m_upperLeft.y );
pDC->LineTo( pDoc->m_lowerRight.x, pDoc->m_lowerRight.y );
pDC->MoveTo( pDoc->m_upperLeft.x, pDoc->m_lowerRight.y );
pDC->LineTo( pDoc->m_lowerRight.x, pDoc->m_upperLeft.y );

}

Well since the Upper left and bottom right are points on the view and not the document, the view should determine these values.

I think GetClientRect will return a rect and then you can get the topleft and bottom right such that your X will be across the screen.
