No offence intended, its just that often if you just give someone a hint they can't be bothered to follow it up, they expect complete code samples. I'm pleased it helped, I generally only give an idea of the answer, as by finding out for yourself you learn. Obviously in your case it applied Smile | :)

C# library for visual network layout / flow chart needed

Hi all!

I have a small project where I need to create a visual family tree editor. Before I start reinventing the wheel, I would like to know if there are any free or open source C# library which lets me do the following:

-add, select and remove elements (simple boxes with title is enough) with mouse and context menu
-connect and disconnect elements with mouse.

If I have this, I 'll be able to do the rest myself (attaching some data structure to the visual tree and storing the tree to a database).

Thanks for any ideas.

Oh, that is great, if only it was C#. Anyway, thanks, I'll see if I can port it to C#.

adapting a webcam driver to an existing form

hi
i'm new at c# and i'm using visual studio c# 2008
i have a very large application which needs to take pictures from a webcam to work with them
i found this code (among many other which i haven't been able to get to work) http://www.c-sharpcorner.com/UploadFile/yougerthen/810262008070218AM/8.aspx[^]

notice there, in the extra code the author asks to add for the thing to work, it has already a initializeComponent() since its a form of sorts. BUT notice too that MY application is also a form and pretty much larger, so of course it has its own initializeComponent() with near 150 other componets; the webcam stuff must be in one of the tabs initialized there.

If i let the initializeComponent() be, the compiler says it does not exist in the actual context. i deleted the constructor altogether but then obviously not even the pictureBox appears. but then if i leave the constructor there, but remove the initializeComponent()... what should it had inside instead? the picture box and buttons are already taken care of in the bigger initializeComponent().

so how can i merge this code into mine so i can use the webcam features in there?
any ideas?

i can't download the code from your link. it has a problem. but here is some links which can help you:
http://www.codeproject.com/KB/directx/PrgmngDirectShowappsCS.aspx[^]

http://www.codeproject.com/KB/directx/directshownet.aspx[^]

and the best resource for you is here :
http://sourceforge.net/project/showfiles.php?group_id=136334[^]

if you want to import codes from other projects to your project you shouldn't use their InitializeComponent() function. just add the necessary initialization codes after your InitializeComponent() function. like this :

public Form1()
{
    InitializeComponent();
    // add initialization codes here
    // ...
}

"zip" is a string, not a char.

Secondly use '.'.

you should not use split method as it causes to create string array object
if your requirement is only to return filname without extension the
use this

return new Path.GetFileNameWithoutExtension(s);

Happy Coding

You really question a lot of simple and basic questions here. Although this is not a real problem, you should try and buy a book and read it.

Also: all your messages are turned grey, this is because people think your questions are bad. If you see red messages, people think it is a good question or anwser.

Use System.IO.Path.GetExtension(filename), and you'll get ".zip". There are also methods for getting the filename, or the directory.
