RichTextBox- How to display last line entered.

[Freddie Code]

I'm writing a VC++ .NET application in which I need to present the user with data on an on going basis. The user always needs to see the most most recent data. I'm dumping the data to a RichTextBox. The only problem is that the richtext box keeps scrolling up to the top of the box, showing the use the first data entered. Is there a property of the richtextbox that can be changed to show the last data entered? Or is there a custom control that could do this? Thanks.

If you are dumping the data one line at a time, one option might be to insert the newer info at the top instead of at the bottom. For example: 5 4 3 2 1 instead of 1 2 3 4 5 However, take a look at this article (http://www.codeproject.com/editctrl/history_edit.asp[^]) and see if this will help you out. The article uses a CEdit control instead of a rich text box but it might get you pointed in the right direction. I hope this helps. Good luck with your project. :)

This looks like exactly what I need. Thanks bneacetp! :cool:

OK, I'm having some trouble with Step #2 using this control in another VC 6.0 MFC project. I think it is just a MFC Wizard thing. I'm following the instructions in the Guide: 1. Include CHistoryEdit.h in your dialog class' header file. -Done, no issues :-). 2. Add member variables of type CHistoryEdit for every edit control you want to subclass. -Here is where I have issues. When I use the MFC Wizard to add a memeber variable to my Edit Box, the drop-down variable Type selection dones not show a pick for the new custom class HistoryEdit. It's like the new class is not registered with MFC or something. What am I doing wrong? :confused: 3. Subclass the edit controls in your dialog's OnInitDialog() method. - Not there yet! Thanks.

Have you added the HistoryEdit source files to the project ? The class wizard looks there. Elaine :rose: The tigress is here :-D

I did have the HistoryEdit.cpp source file as one of the source files and that still did not let the Wizard find the class. I did discover a work-a-round. I added a member variable of one of the default MFC types "Control" and "CEdit". I then searched the code for the declaration of the variable and changed it to "HistoryEdit" type. This works and I can now use added custom control functions. However, it still would be nice to know the "right" way to do this. ie, how to make the Wizard recognize custom class types without using the back-door approach.

It's the header file the class wizard looks in for the declarations and the CPP file for the references. Always add both to the project source files. Elaine :rose: The tigress is here :-D

I'm not sure if it's possible to make the Wizard recognize those classes, but what you did is right anyway. Just to clarify, both of the following options will work: 1 - You manually declare new variable members in your dialog class and then manually subclass the windows in OnInitDialog(). 2 - You add a variable member through the wizard, which also adds the subclassing in DoDataExchange(), which is called through CDialog::OnInitDialog(), and then manually change the class of the control in your dialog class declaration. The latter is easier, of course :) -- jlr http://jlamas.blogspot.com/[^]
