Is there a way to display a treeview with the root on bottom?

Yes and no, it depends on how much effort you're willing to put into it. There's not a toggle that you can switch, but you can extend a treeview to suit your own needs. ~~That would be done through owner-drawing[^].~~

It might be that one of the prebuilt-trees out there support an upside-down view Smile | :)

--edit--

I doubt that owner-drawing let's you change the position of the item. Another option would be a Panel where you add UserControls as childitems with the docking set to the bottom of the control. Scrollbars should appear when the items grow beyond the size of the panel.

You want "come one slim"? Really? You think we know what that means?

faizych wrote:

That depends on what all that means. If it means no headache for you because someone here does it for you then good luck, not me. I help people that do the work themselves. Part of doing the work of software development is learning the technologies you need to use so that you can understand how they work. The reason we want to know how they work is because when we know that, we know how to proceed with our work using them. See how that all comes together? Wink | ;)

lol sorry about that what i was trying to do was give the situation. That let's say i am looking for someone with a body type: slim and height: from 5 to 6.. and age from: 18 to 20.. so should i go into xml and filter all that out and then put it in the array or should i convert to whole xml into array and then filter the data out.. of the people who come under all those criterias. because what i am trying to do is that i need a control or whatever i can do to make it into a box which shows the info about one of my match.. and then i can click the next button to show me the next match.. so i thought the easiest way to do that is put all the results in array and then go through them and that control will work easier..

and what i mean by how can i do it good and best without alot of headache is not that i want someone else to do it for me.. i just want the way so i don't end up doing something totally wrong and end up no where.. i just want the directions.

thanks

Sure, that sounds fine, unless of course you have 100 million of them, or maybe even other considerations that we have no way of knowing they exist. But otherwise, all things being, um, something that sounds so peachy.

Using Visio 2007

Helo,

I need to create a dynamical organization chart using visio from C# code.

Currently im using the following code only to test nothing special.

if (openFileDialog1.ShowDialog() == DialogResult.OK)
               {
                   axViewer1.SRC = openFileDialog1.FileName;
                   Microsoft.Office.Interop.Visio.Application app = new Microsoft.Office.Interop.Visio.Application();
                   Microsoft.Office.Interop.Visio.Page currentpage = app.Documents.Open(openFileDialog1.FileName).Pages[1];
                   Microsoft.Office.Interop.Visio.Document stencil = app.Documents.OpenEx("Basic_U.vss", (short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenDocked);
                   //Microsoft.Office.Interop.Visio.Window stencilwindow = currentpage.Document.OpenStencilWindow();
                   //app.SaveWorkspaceAs(@"C:\Users\Chris\Desktop\tezt.vsd");

                   Microsoft.Office.Interop.Visio.Shape shape2 = currentpage.Drop(stencil.Masters["Square"], 10, 7.50);

                   // create a dynamic connector from the stencil master collection
                   Microsoft.Office.Interop.Visio.Shape connector = currentpage.Drop(stencil.Masters["Dynamic connector"], 4.50, 4.50);


               }

now the problem is here. On my computer the application is working fine because i have Visio 2007 installed and shapes are added etc.. but when the application is going to be used by the clients and they dont have visio installed the whole applicaiton wont work. Is there a way which i can create the charts dynamicaly at runtime without visio being installed??

I don't think so, it's like getting on a train where you didn't buy a trainticket.

If the app doesn't work, try the 'try-catch' method around the area's where you are trying to do something with the visio files.

No the application works fine on my computer where i have visio installed but it dosent work on the other computer im testing it on that dosen't have visio installed. Is there some other librariy that i can use to draw charts. Because to be honest the main reason im using this is to create a family tree.

Re: Using Visio 2007

If you just want to draw charts you can
1. make your own library
2. use an external library.
You could use Dundas Charting (you've got to pay for this)
or you can use something like this: charts[^]

Unfortunately you need visio installed to use the Visio COM Interop Objects. D'Oh! | :doh:

Fishing for Ideas (C# file copy)

From time to time I would like to have the ability to copy a file through the network to some of our remote locations but control the bandwidth because they have much slower connections. I've used nullsoft's nscopy before, but figured this would be a good learning expierence if I could create my own app to be more fine tuned to my environment. I have a general idea of what I need to do, but am not sure where to start. Looking at the system.IO.file.copy method it doesn't look like there's an overload that controls bandwidth. Then I started to think maybe I need to take the file and create a file stream and pass that through the network somehow, but that's where I get stuck. Has anyone tried doing something like this before? I'm just looking for a nudge in the right direction.

Thanks!

You're already moving in the right direction Thumbs Up | :thumbsup:

You'd indeed start out with a streamreader and a streamwriter. Instead of filling the stream at once, fill it block by block of data. This will result in a read/write loop that you can throttle if desired.

There's a handy sheet-cheat here[^].

AH! Thank you very much for the help and the sheet-cheat eddy! I continued to get stuck because I was aproaching the task thinking I could handle the bandwidth speed from the network side and not the stream reader!

C# Networking: Handling Clients?

Ill try keep it short, Usually when I write networking applications, I spawn a new thread every time a client connects to the server. This works fine for my small time applications, but how do people who deploy large scale servers handle client communications? If you have thousands of users, for example a simple busy irc server, surely you cant spawn threads for all the users, what other methods are there?
