Absolutely! Use Doxygen - it's fast, flexible, and free! It rocks! Cool | :cool:

I was not very clear in my first post, so let me clarify here:

Say I have 4 classes, CBiggestObj, CBigObj, CSmallObj1 and CSmallObj2 and the code looks like this:

class CBiggestObj : public CDontCare
{
   CBigObj m_bigobj;
}

class CBigObj : public CWhatever
{
   CSmallObj1 m_obj1;
   CSmallObj2 *m_pobj2;
}

I need some software that will show me visually (with balloons and
arrows, like in a diagram) that CBiggestObj has a member CBigObj object and that CBigObj has 2 members, an object of CSmallObj1 and a pointer to a CSmallObj2. I don't need to know where the classes are inherited from.

Yep, Doxygen will do that for you. Be sure to install the (free) Graphviz package that draws all the pretty diagrams.

When you say Doxygen will do that for you, do you mean without any change to the source, so it can parse C++ declarations, or do you mean after you've manually inserted comments?

I suspect the original poster wants the former, rather than the latter.

We use it as part of our build process at work to generate class documentation (from manually inserted comments). Doxygen even generates a non-empty log file if it detects (to the best of its ability) invalid comments, which helps us keep our documentation honest.

Hi,

I have a SDI app with a scrollview derived view class, which I try to paint using GDI+. So far so good. Previously, I used "old" GDI to draw, and simply took the scrolling into account by doing such as this:

<br />
CPoint where = GetDeviceScrollPosition();<br />
Pen penn(Color(0,0,0), REAL(width));<br />
pdc->DrawRectangle( &penn, rect.left - where.x, rect.top - where.y, rect.right - rect.left - where.x, rect.bottom - rect.top - where.y);<br />

Now, it seems like two things happen when I scroll. The old "drawing" moves up, like I want it to, and the view redraws itself, without regards to scrolling. In other words, as if I haven't scrolled anything yet.

If anyone can make any sense of this, please help me out!

Reflection in c++

Hi
I wanted to produce a mechanism like Reflection in c++ (without using dot net framework).can i do that..? How..? Is there any framework available to achieve this mechanism?

Or simple i will provide a class name in a string to a function that function will return me a new object of that class. is it possible in simple C++ (Not using MFC or dot net). If yes please let me know also.

Thanks in advance
Ravi

It's possible to emulate the effects of reflection and there are several attempts to provide this on the net. A few starters are http://cppxmlobj.sourceforge.net/index.html[^] and https://sourceforge.net/projects/reflection/[^] - have a look through google for more.

I am also not familiar with Reflection. However if all you want to do is to produce a new class object based on the string passed into a function, one of the factory methods would work fine. For achieving your simple aim, the Builder method or the Abstract Factory should suffice.

I believe that there are various cool methods already on CodeProject on these subjects.

PC Communication using VC++ and TAPI 3

13-Nov-03 1:03

i have written an application..MFC in VC++ to carry out PC 2 PC commn
using TAPI3.0(API's)

all the API's including Answer( ), Disconnect( ),all r wrking that is i am able to dial an IP and connect to that PC,answer a call at the other Pc,
and Hang up frm either sides..without any problem..voice is also being carried..

when i tried Hold( )to hold my call...it does not happen..or the Transfer..
there is no sample code for these and i am utterly confused..

the function does not return OK(will return this if carried out properly)
instead some error..number..is given..

Thanks for the details Michael, Let me explain in detail,

TSP is TAPI3.0

the functions r ITBasicCallControl::Hold

and ITBasicCallControl::Transfer

linehold and linetransfer are for TAPI2.0

my application is completely in TAPI3.0

and the other functions in it like..

ITBasicCallcontrol:: Answer and Connect r wrking perfectly fine..

and i have nothing to do with the modem..

cos this is for PC 2 PC communication

Pls. let me know

Which TSP are you using?

Hold and Transfer are very rarely supported by modems and other similar devices.

What error number do you get returned?

This app JulMar EnumTAPI[^] will show you the capabilities of the TAPI device you are using. You should at least be able to see if the device supports lineHold and lineTransfer.

I need to do this as well but for me the function returns zero and so does GetLastError() after it. What am i missing?

Cheers,

This doesn't make sense, unless maybe you aren't:

ncm.cbSize = sizeof(NONCLIENTMETRICS);

before calling SystemParametersInfo().
