Head over to http://www.codeproject.com/printing/[^] and read it. That'll give you a start, at least. The really hard bit will be HTML - i wish you luck with that, it could end up being quite a bit of work.

Does anyone know how to make a combobox sort data dynamically? Is there a CBS_SORT and if there is, how do I call it (note that I'm not creating the combobox dynamically)?
Thanks,
~ Selevercin

Yes, but how do you do that with code?

If you specify the CBS_SORT style the strings are automatically sorted when they are added with AddString().
You said you are not creating the control dynamically, so I assumed you were using a template to create it. If you are creating the control dynamically, then you use the Create() member function, and add CBS_SORT as one of the styles in the dwStyle parameter.

Yes, but I need to be able to change the setting during the program. Can I add this ability in the program? I AM using the dialog control maker (not dynamic). Thanks VERY much,

Ok, now I get what you want
You can use the ModifyStyle() function. Just remember that some styles can not be changed after the control is created, I am not sure if CBS_SORT is one of them or not. Also, after you modify some styles you may have to call RedrawWindow() or SetWindowPos() with the SWP_FRAMECHANGED flag in order for the changes to show.

When the user changes the selection of a combo box, I receive the CBN_SELCHANGE notification (via the MFC callback mechanism). The problem is that the UpdateData(TRUE) with the handler sets the CString to the previous.
Who was this guy at Microsoft who might think that if a user changes the Combo box selection that I would be interested in the previous selection, not in the new?
Btw, I tried catching the CBN_EDITCHANGE, CBN_EDITUPDATE, CBN_CLOSEUP, and CBN_SELENDOK notifications. They all return the previous selection, except for CBN_EDITCHANGE and CBN_EDITUPDATE that are never called.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

AFAIK, the window is not actually updated until the message handler returns.
Use GetCurSel() and GetLBText() to get the new selection.

Using UpdateData(TRUE) would have been too simple, isn't it? Btw, when do I call these functions?
What I want to do is to update another control when the user changes the selection.

You should be able to call them from your CBN_CHANGE (from memory & it's early - something like that) handler. Heck, you could even put them in your DoDataExchange() method if you just want to keep using UpdateData() (make sure you only do it when going one way).

You need to call UpdateData(FALSE) in your handler to get the current value updated from the combo. Then you can do your other processing and call UpdateData(TRUE)

Phil, I think it is the reverse. Anyway, UpdateData(TRUE) don't get the value from the combo box.

in hw3.h you need a semicolon after the closing brace in your class declaration.
#ifndef hw3_h
#define hw3_h
class Date
{
private:
int month;
int day;
int year;
public:
void setdate(int, int, int);
void increment();
void display();
}<font color="red">;</font>

the 3 lasts errors come from this:
int days_array{} = {31, 28, 31, 30, 31, 30,31, 31, 30, 31, 30, 31};
I suppose, you wanted to write that:
int days_array[12] = {31, 28, 31, 30, 31, 30,31, 31, 30, 31, 30, 31};
.... I think ....

i hope that someone can answer this question cause i spent about two hours on it last night and came no closer.. I have this sample code on socket programming, but it says that i have to link in the ws2_32.lib for support of some classes. Unfortunately i don't know how to enable this option in visual studio.net!!!! can anyone answer this. Can i compile socket programs using the visual IDE or does it have to be done with the command prompt. If so, could you help me find a tutorial that might help on using the command prompt compiler? Thanks, any help would be appreciated. I have joined this group because a lot of you seem well experienced with visual c++. i am dying to make some socket programs..
