[golyg]

Hi all,
i am trying to set a variable through a pointer but I keep recieving an "Unhandled Exception in app.exe Access Violation" error.

Any ideas why?

thanks

Hi

Suppose a int variable and a pointer to it:
int nData = 2;
int* pnData = &nData;

Change the value as:

*pnData = 10;

Suppose you pass a pointer to a int in a function as:
void TestFunction( int* pnData)

To set up a variable in this function, use

*pnData = 5;

I think I may have mislead the problem, here is variable and a call to a function:

nNewStatus = 0;
m_pDoc->SetChargeStatus(nNewStatus);

---------------------------------------------------------

here is the function:
void CACMSDoc::SetChargeStatus(int nNewStatus)
{
m_nNewStatus = nNewStatus;
}


in the function, m_nNewStatus throws an exception.
thanks for the help,
m

Check initialization of pointer m_pDoc.
