how do i write a function that generates random numbers of type double between two bounds with a uninform probability density to calculate the mean and the standard deviation of a distribution of real numbers
can someone help me with codes please

double getRand(double dMin, double dMax)
{
return dMin + ( rand() / (RAND_MAX + 1.0) * (dMax-dMin) );
}

Assuming the bounds are uMax and uMin
double uResult = (uMax-uMin)*( (double) (rand()%100))*0.01 +uMin;

Well, studying the language should sooner make you a fantastic problem-solver...

thanks Pallini for the encouragement
but unfortunately i have an assignment to summit on histograms, chi square and gaussian random numbers and i don't know what to do because i have been struggling since last week but to no avail
|

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 ?

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!

I am using following piece of code to update excel using dde . I am updating the g_count
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?

What's the difference between upcasting and downcasting?

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();

Why do you need such multiple inheritance?

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.
