Not only that. The program seemed to be quite broken.
That's why I posted a small sample program.

Form Designer

Nish Nishant21-Mar-02 21:31

21-Mar-02 21:31

There is a pretty good chance that I might be asked to write a form designer of sorts. MFC is allowed I guess.

But is there any specific path I need to follow? Are there any pre-made class libraries for this.

basic functionality includes the ability to drag and drop controls [edit boxes, combos, static boxes etc.] into an area and to be able to resize them with the mouse. Also move them around and arrange them.

It's a big ask Frown | :-(

I need to basically mimic the C#/VB form designer.

Any ideas are hugely appreciated...

Also, how do I then save it. I need to pass all this information a a server via HTTP. Need to POST data to a Java Servlet. I wonder how I can do that.

Anyway will XML be a nice way to save all this stuff???

Means also using expat or MS XML parse Frown | :-(

Designed form will be a web form? Or Win32 dialog?

The form will be shown in various places

(1) a web form generated by jsp/servlets
(2) a java application on linux
(3) a win32 application
(4) palm devices

The saved form will be mostly meta data. A form will consist of multiple controls and I just save their information like size, position, other custom data. Then of course there are a lot of non-visual components associated with each form and I am anticipating a MASSIVE headache for me Frown | :-(

Nish

p.s. right now I am takin it one at a time and focussin g on the drag-drop-form-designer tool

Doesn't sound good to me. If you need one form for the web, Win32 and other platforms, you'll need to adopt lowest common denominator approach - note that you can't place a control at (x, y) on the web page. There's something called positioning style sheets, but AFAIR it's not available on all browsers.

Ask your bosses if they really need one form for everything Smile | :)

This is supposed to be some kind of platform independent form. The actual rendering of the form would vary between end interfaces.

Inheritance

Jack Handy21-Mar-02 21:10

21-Mar-02 21:10

I have a class CField with a public function Paint() and I derive a class from it called CMyField. I then create a CMyField m_Field private (or public) object in another class and get this error:

error C2248: 'Paint' : cannot access public member declared in class 'CField'

Any ideas?

Thanks,

Jack

Can you show us your class definition line for CMyField?

Jack Handy21-Mar-02 21:26

The CField class:

class CField {
public:
	CField();
	virtual ~CField();
	void Paint();
	...
};

The CMyField class:

class CMyField : CField {
public:
	CMyField();
	...
};

Nish Nishant21-Mar-02 21:35

21-Mar-02 21:35

The CMyField class should be declared thus :-

class CMyField : public CField {
public:	
        CMyField();
	...
};

Notice how I have added "public"

Hi,
I have an edit control, for which i had done some validation calculations when the edit control receives EN_KILLFOCUS.But after entering some value if the user doesn't click anywhere,then i would like to validate the entry.My problem is, it never recives EN_KILLFOCUS until i click on anyother control.
Any idea?

in our app we disable the 'ok' button until all controls like you are describing have lost focus ... we also tell the clients that they must tab out of the box to get the calc to work ... another solution is to put a 'calc' button next to the box that does nothing but when they click it you get the 'lost focus' message and it all happens

heh Smile | :)
