I created an SDI in VC++. When I derive classes from MFC classes they are shown in the class wizard and windows message handlers can be added to those classes. When we again derive from these classes which are derived from the MFC classes, those are not shown in the class wizard classes list. So I m having problem adding windows message handlers to those classes which are at the second level of inheritance.

For eg:
I made a class named CListRs with base MFC class CListView. Then when I take the class wizard I can see CListRs in the class name combo box and is able to add message handlers to it. Now I made another class CMailView derived from CListRs. But it is not seen in the class name combo box of the class wizard. So I m unable to add windows message handlers to this class.

Can anyone please help?

Hoping for a reply

Try deleteing your *.CLW file and hit Ctrl+W. This will ask for create class view from exisiting file. add all file and create class view.....

Hi,

this is another dirty trick wich I use to do the same thing.
Derive your new class from CListView, this will add your new
class to the CWL. Then replace CListView with CListRS.

This works for me, hope it does the same for you

in the header file of the new class you might have this statement.

class xyx : public CListView
so replace CListView with some other name.

Like Mr.Prakash wrote:

but check alsoo the implementation file (*.cpp) to make sure that all CListView
occurences are replaced

First close your Visual Studio, then delete CLW and the start again VS. It should work.

That combobox is hard-coded to contain only MFC classes, not user-defined classes.

Did you check the posted articles to see if there's an ADO class you can use? I seem to remember seeing one.

Right way to do

Hi,

GUI in mind to be made in MFC:-
On the left pane, there will be links. Clicking each of the links shows up a different UI(with controls) to its right.

An example would be the Options section on the left with My Settings/My BookMarks/.... on the left here in codeproject. Clicking each of them would show a different UI to its right with its own layout and controls.

Is CHtmlDialog the only way or Is there any other recommended mechanism?

Thanks

Hey, cool. What is your MVP in ? Did you get to Seattle, or are you a new awardee ?

I'd just have a splitter window and a form view on the right, with a bunch of different dialog templates tied to the buttons on the left. A CHTMLDialog seems very limiting to me, I've never used one.

Printing/Imaging (printer drivers,GDI ) Iam new awardee and not been to seattle.

I actually was doing it the same way as you suggested with buttons on left and splitter window
on formview, when I hit CHtmlDialog in msdn.

Thanks for thoughts

You could do a formview in both panes, and use the article from cp that describes how to put html links in a dialog box, like this one:

I would use a CRichEditView (so that hyperlinks can easily be displayed, and you can scroll vertically) in the left pane and a CHtmlView in the right pane.

Hi,

I need to print the SDI dialog and found the following code

http://www.codeproject.com/printing/prntscreen.asp

The code worked fine but the print out image is a
kind of small.

Does anyone know how to change the setting to print
the bitmap image a bit larger if possible?

Thanks,

Kevin
