CBrush *white = new CBrush;<br />
CBrush *black = new CBrush;<br />
<br />
CMyChessDoc* pDoc = GetDocument();<br />
ASSERT_VALID(pDoc);<br />
white->CreateSolidBrush(RGB(255,255,255));<br />
black->CreateSolidBrush(RGB(0,0,0));<br />
<br />
for (int i=1;i<=8;i++)<br />
for (int j=1;j<=8;j++)<br />
{<br />
pDC->Rectangle((i-1)*56,(j-1)*56,i*56,j*56);<br />

Yes. The problem is somewhere else.
What line of code causes the exception? What is the specific exception?

There's lots of places that assertions can occur -
you really need to be more specific.
The only thing I can see is you're not freeing the brushes when you're done with them.
Are you depleting all your GDI resources??

Hello,
Yes, i am deleting all GDi resources in desctroctor
I found where the problem is, the creation of those CBrushs cannt be in OnDraw Method, because OnResize method, it will create again the bruths
thanks

FWIW, you can simplify your code and reduce the chance of leaks
something like this:
void CMyChessView::OnDraw(CDC* pDC)
{
CBrush white(RGB(255,255,255));
CBrush black(RGB(0,0,0));
CMyChessDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
for (int i=1;i<=8;i++)
for (int j=1;j<=8;j++)
{
pDC->Rectangle((i-1)*56,(j-1)*56,i*56,j*56);
}

hello!
How can i create a shortcut to a file on-the-run ?
If I could specify the folder where to create it, it would be great!
Thanks!

Hello
I need to write a DLL for some functions that I have which depend on a separate lib file.
when i write a short test program that uses the functions as is and link against the lib file, everything works great. But when i take the same functions and put them in a DLL, it doesn't work (i get some unresolved references to any function that I use from the lib file).
Am i supposed to do anything special to get it to recognize the functions from the lib?
thanks for your time.

effectively, there are some things to get done for a DLL to work properly.
you should start by reading this[^] article...
|
|
|
|
|
yeah i already know that bit
when i have regular functions that don't depend on the library (the one that I didn't write) the dll builds just fine
it's when i use the library's functions in my dll that i get the linking errors.

You haven't specified what type of DLL you're using or how you are linking
and/or binding to the DLL at runtime so it's difficult to give a specific answer.
I do know you will find links to a solution here[^]
If I had to guess, I'd say you need to link your application project
to the link library produces by a build of the DLL project, but again,
this is a wild guess since you gave no specifics.

I am getting a exception while running in the debugger. It happens inside a memcpy and VS 2003 C++ stops the app and opens the assembly code for the memcpy. Is there anyway to find out which memcpy in my code cause this problem.

Hi Friends
I am not able to get the Selected Date from the DatePicker. It is showing me the Current DateTime always.
I am new with VC++.
//Initializing
, m_Date( CTime::GetCurrentTime())
DDX_DateTimeCtrl(pDX, IDC_DATE, m_Date);
And then i am Changing the Date in DatePicker, and on Button Click Event,
i have the below instruction, where i need the Selected Date but instead it is showing me CurrentDateTime()
SELECT Polhsh_ID FROM Polhsh WHERE Installation_ID = %d AND Pelaths_ID = %d AND ActionType = '%s'AND Hmeromhnia= #%s# "), Installation_ID, m_Promhtheytes.GetItemData( m_Promhtheytes.GetCurSel()), ActionType, m_Date.Format( _T("%Y/%m/%d")) );
But i am always getting the Current DateTime.
I know it must be something simple, But i am completely new with VC++.
I hope if anybody gets time, give me some help.
Thanks
Cheers
Menon
