Well, studying the language should sooner make you a fantastic problem-solver... Roll eyes | :rolleyes:

So you need gaussian (not uniform) random numbers?

My dialog is resizable with a list control, and the list control's rect is the whole of dialog's client rect, call CListCtrl::SetBkImage to enable background. My question is how to autofit(stretch) background with the dialog when resizing? Thanks.

What if your try call ::SetBkImage again when the OnSize member is triggered ?

Multiple Inheritance problem

16-Nov-09 1:36

void CMyDlg::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);

// TODO: Add your message handler code here
if (IsWindow(m_ListCtrl.m_hWnd))
{
CRect rect;
GetClientRect(rect);
m_ListCtrl.MoveWindow(rect);
m_ListCtrl.SetBkImage(::LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BKIMAGE)));
}
}

problem still unresolved, autofit(stretch) no effect! Thanks!

as my excel connect it cell get updated with value = 10 ; But I am not able to send string

value i.e. "xyzabcd" etc to the excel cell ,so how can I send string to the excel sheet

using dde

int g_count = 10;
short xltableData[100];
// tdtTable record...
xltableData[0] = 0x0010; // tdtTable
xltableData[1] = 4; // 2 short ints following
xltableData[2] = 1; // # rows
xltableData[3] = 1; // # cols

// tdtInt record...
xltableData[4] = 0x0006;
xltableData[5] = 2;
xltableData[6] = (short)g_count;
DdeCreateDataHandle(g_idInst, (UCHAR*)xltableData, 2*7, 0, g_hszItemName, fmt, 0);

Sorry, my bad. After looked at the prototype of DdeCreateDataHandle[^], it really takes a LPBYTE argument.

Hi all,

I have one problem in using Multiple Inheritance, please go through below Code

class Base1
{
 public:
   void Show()
   {
    cout<<"Base1";
   }
 
};
class Base2
{
 public:
   void Show()
   {
    cout<<"Base2";
   } 
};
class Derived: public Base1,public Base2
{
}
main()
{
Derived d;
d.Show();
}

Error: error C2385: ambiguous access of 'show'
Please provide some solution for the above code. Can virtual Base class concept work in this,if yes then how?

d.Show();

The error is because the compiler do not know which Show() function it should call. Show() of Base1 or Base2. Actually which one do you want to call?

You have to tell the compiler which one excatly. like

d.Base1::Show();
or
d.Base2::Show();

Hi all

I developed an application using MFc and oracle.

The mFC transactions will be update in to oracle DB.

The app exe works fine in my PC, where as if i run on other pc's, it shows that it requires "Oracle Client".

Is ther any solution to run the exe without installing the oracle client.
