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.

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? 
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.

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.

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

I am trying to find a video capture board for my PC that:
1) captures video from either a standard TV cable or line in cables
2) is able to output to a VCR or TV
3) I can use to turn a TV into a computer monitor
Is there anything that does all this with decent quality? Are there any other forums I should post at instead? My email is f-m-n@ig.com.br. Thanks,
fmn

The function you are looking for is SQLConfigDataSource().

Next question is how i call this function from the setup program?

You call it just like you would any other function. Check the documentation for the parameter list.

Hi guys,
I have to make a dialog based application in VC++,in which I need to output some audio frequencies through the speaker system as I did in C by simply calling "sound(frequency)" from dos.h.
Here also I need the same thing in the environment of VC++,i.e., the audio frequency may be supplied at runtime or statically given at compile time.
I need the analogous of the following in VC++, which I found in C within dos.h.
C------------------------------ VC++
sound(unsigned)--------- ?
delay(unsigned)--------- ?
nosound()--------------- ?
Can any one of you help me?

What about
BOOL Beep(
DWORD dwFreq,
DWORD dwDuration
);

Ok. So I'm working on a web service client in unmanaged C++ which is derived from CSoapSocketClientT.
I know that when creating a web service in .Net(C#,vb,c++) one have to use (through CookieContainer property) CookieContainer class to maintain session between requestes to the server. Is there something similar for unmananged C++ web service client? Or is generated (at "add web reference.." time) code's doing it somehow magicaly on it's own?
Please help!

My question is why do the system wide hoks are done with dll and not generally in normal c++ file.That means if I
want to register to intercept the message why the hooks are put in the dll and how it is possible that using dll
it intercepts all the message while through normal c++ it is not.
|
|
|
|
|
Because a DLL can be mapped into the address space of another process. An EXE can not be mapped into the address space of another EXE.
If you only want your hook to act on the EXE in which it is contained, it does not need to be in a DLL as long as the hook can be set to type LOCAL. Some are only GLOBAL hooks, and they must always be inside a DLL to work correctly.

In SDI application, what is the difference between ondraw(),onpaint() and on initdialog().Please explain or give a useful reference.
Thanks.
Be FaithFull To Your Work.

OnDraw() function performs screen display, print preview etc.,. Its a member of CView class.
OnPaint() function performs repaint the application window. Its a member of CWnd class.
OnInitDialog() is used for performing some special initializations when the Dialog box is being initialized. Its a member of CDialog class. It is somewhat a constructor type only.
Work hard and Bit of LUCK is KEY to SUCCESS
