I am trying to get into view the last bit of text posted to the multiline Edit Box via these lines of code:-

m_strOutput+= m_strGeneral + crlf; // Total display string; adding m_strNewText at the end
SetDlgItemText(IDC_OUTPUT, m_strOutput); // Display the new text appended onto the old text

m_Output.GetScrollInfo(SB_VERT, &scrollInfo, SIF_ALL);
scrollInfo.nPos = scrollInfo.nMax;
m_Output.SetScrollPos (SB_VERT, scrollInfo.nPos, TRUE);

UpdateData(); // Refresh the control

m_Output is the Edit Box and I was trying to set the scrol position to the current maximum, but no luck.

You need to set your scrollinfo structure size and variable you need to get in your struct.

si.fMask = SIF_POS; //for instance you need the scroll pos
si.cbSize = sizeof(si); //this is pretty weird but required according to MSDN.

same thing goes to SetScrollInfo

Why are you calling both SetDlgItemText() and UpdateData()? A simple call to m_Output.SetWindowText(m_strOutput) will suffice.

Ok thanks for that, but still lost in the scrolling problem.

scrollInfo.fMask = SIF_POS;
scrollInfo.cbSize = sizeof(scrollInfo);

m_Output.GetScrollInfo(SB_VERT, &scrollInfo, SIF_POS);

//just change the mask if you need other info

I tried the following code, but it only placed the thumb at the button, I still had to use the mouse to have the lastest posted data displayed.

m_Output.SetWindowText(m_strOutput); // Display the new text appended onto the old text

m_Output.GetScrollInfo(SB_VERT, &scrollInfo, SIF_POS);
scrollInfo.fMask = SIF_POS;
scrollInfo.nPos = scrollInfo.nMax;
scrollInfo.cbSize = sizeof(scrollInfo);
m_Output.SetScrollPos (SB_VERT, scrollInfo.nPos, TRUE);

Do I need to do something else?

try to get the every API working before throwing everyhing inside.

Does

GetScrollInfo(SB_VERT, &scrollInfo, SIF_POS); API work?

check the return value

if yes, then,

check if
SetScrollPos (SB_VERT, scrollInfo.nPos, TRUE);
work by supplying a simple nPos value like 100.

You might also consider using

m_Output.PostMessage(EM_SETSEL, 0, 0); //the caret position

Remember to start from simple or else you get lost somewhere.

overloading operator[] question

In C++ when using the array index overload operator, is there any way to tell if the operation is a lhs or rhs based.

for instace, assume

class intArray {...};
intArray intA;

and assume that intArray::operator[] has been defined

can I tell the difference between ...

int a = intArray[1];

... and ...

intArray[1] = a

... in the method. If so, please can you state how.

it is always the same.

<font style="color:blue;">int </font>Array[1] = a;

is equivalent to :

<font style="color:blue;">int </font>(Array.<font style="color:blue;">operator</font>[](1)).<font style="color:blue;">operator</font>=(a);

only ++ and -- operators have a way to tell if they are pre or post incrementation/decrementation :

<font style="color:blue;">const</font> T& <font style="color:blue;">operator</font>++ (T&);          <font style="color:green;">// pre-incremetation</font>
<font style="color:blue;">const</font> T& <font style="color:blue;">operator</font>++ (T&, int);     <font style="color:green;">// post-incrementation</font>

when define operator[] The Debug version of the library asserts if the subscript (either on the left or right side of an assignment statement) is out of bounds.

it limits your index of array ,normally between 0 and up bounds,once beyond ,will be asserted error flow
understand?

It's customary to write two [] overloads, one const and one not:

class X
{
public:
  X& operator[](int n);
  const X& operator [](int n) const;
};

The non-const version will be called for l-values, or r-values that contain a non-const X. The const version will be called for r-values that contain a const X.

Unfortunately you can't really tell from the non-const version whether it's returning an lvalue or rvalue.

Calling a Class Member from a Tread

I have a MFC Dialog based application which will update a Edit Box when an event is set. A thread is waiting on this event.

But how do I call a procedure from this thread to update this Edit Box.

2 questions;

1. How should this procedure be written (member of dialog or not)

2. I can pass in some data via a structure when I create the thread, but how can I pass in either a pointer to the Dialog or this procedure.

I did try passing in the dialog 'this' pointer but could not see the procedure;

CMyDialog::UpdateData() This is the update data procedure.

I am stuck - help

1. i would go for a member function
2. pass this then in the thread callback cast the pointer again to your dialog

(CMyDialog*) pxDlg = (CMyDialog*) pParam;

But personnaly, i would just pass the handle of the window, and post a message from the thread to this window

SendMessage, PostMessage and RegisterWindowMessage

Be very careful when using UpdateData(). It can prove to be not very helpful.
