Preserving Undo Buffer between Saves

I'm using the RichEdit v3 control in my MFC SDI app. But I'm bypassing the the normal CRichEditCtrl's undo functions and using EM_UNDO/EM_REDO to provide multi-level undo. However, when I save my document, the undo buffer disappears. Does anyone have any idea what might be causing this and/or a possible way around it? Thanks in advance

Hi,

In MDI application, if you have a button in toolbar with ID
"ID_WINDOW_TITLE_VERT" or "ID_WINDOW_TITLE_HORZ", you can re-order
child windows by click this button. you don't need do anything just
assign the ID to to your button. does anyone know what are messages
asscoicate those two IDs? because I want to create a MDI application,
allow user open multi-windows at one time and all child windows
automatically ordered horizantally or vertically.

Thank you in advance.

CArchive << operator

Prateek Kaul8-Dec-01 2:55

This is regarding a class called CArchive provided with MFC.

There are some overloaded operators "<<" and ">>" for inseration and
extraction in class CArchive.

One of them is:
friend CArchive& operator <<( CArchive& ar, const CObject* pOb );

The question is why the above operator is friend function???

The inseration and extration operators for the CObject class have been
defined as global friend functions whereas the same extraction and inseration
operators for basic data types such as int, float etc have been defined in
the CArchive class itself.

Why such a design? The CArchive class does not access any private or
protected memeber variables of the CObject class. Hence the query.
The source code is written as:

friend CArchive& operator<<(CArchive& ar, const CObject* pObj)
{
ar.WriteObject(pOb);
return ar;
}

and

CArchive::WriteObject()
{
/// .....lots of code but no private variable of CObject accessed
((CObject*)pOb)->Serialize(*this);
}

The is no accessing of private variables of CObject in any place.

Then why the << operator is a friend function??

I will be greatly obliged anyone could answer my query. Confused | :confused:

Hi.

I was wondering if there any any sources and information etc for people programming for industrial systems. By this, I mean accessing IO (Digital/Analog) and connecting to PLCs ...

I know there are many manufacturers sites but I have found nothing that really does justice to programming in industrial based environments (like Labview etc)

Hi. I have a backround thread function that I need to call many times to do calculations. I was wondering if it is OK for me to call AfxBEginThread time after time without knowing if the first call to it has finished? The calculations may take a while and I could need another thread to do another calculation using the sanme function. I made a test program and it does not seem to work.

If the above does not work, can someone suggest something that does work so that I could definitely have more than one thread going using the same thread function.

Thanks

If you have a calculation function which you want to start as a worker thread, you may start it as many times as you want to. But if they all access a common shared variable, you might get into trouble. Might have to try one of the thread sync mechanisms

(1) Construct the CToolBar

(2) Create a toolbar resource

(3) Call Create() [pass the resource id]

(4) You prolly want to create it on a dialog. If so resize the dialog accordingly

I try to create a toolbar in a dialog like this, but it not works.
BOOL CTempDlg::OnInitDialog()
{
...
...
m_toolbar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_NOALIGN))
m_toolbar.LoadToolBar(IDR_TOOLBAR1))

return TRUE; // return TRUE unless you set the focus to a control
}
Something wrong in my codes? In fact, I want to create a toolbar just in a CWnd, can I? "(4) You prolly want to create it on a dialog. If so resize the dialog accordingly", How to resize the dialog?
Thank u for your answer.

Just a couple of questions

7-Dec-01 17:55

First, does everyone use the wizards to start off a project. They seem a little annoying and create alot of code that is hard to follow.
And second, is there a simple little hello world program out there that uses MFCs

In this case stdafx.h contains only one line
