I need some input on how to go about implementing C# code to allow me to do the following:
Say I have an application that needs to be able to read an XML file. Inside this xml would be the name of a college/university and the sports programs they offer. Obviously, some of the schools would offer a large variety of sports programs, others a minimal amount, and some no sports programs at all. So it would be something similar to
<Application>
<school "university of a">
<sports>volleyball</sports>
<sports<football</sports>
<sports>basketball</sports>
<school>
<school="university of b">
<sports>volleyball</sports>
<sports>football</sports>
<sports>basketball</sports>
<sports>baseball</sports>
</school>
<school="university of c">
</school>
<school "university of d">
<sports>volleyball</sports>
</school>
and so forth. The reason for the xml file is so that if a sports program is added/deleted, then I would have to redistribute the xml file only and not a new application. I am thinking I need to use a table but I cannot picture the C# code. I don't know how many schools or sports programs so it would have to be dynamic, like an ArrayList.
Can anyone offer any suggestions/input?

You have the data structure already. When you load the file into an XmlDocument object, you will have the schools as child nodes of the root node, and the sport programs as child nodes of each school.

Shoot - I retyped my posting and I left part of it out. I apologize for my error.
I am actually wanting to display this in a combo box, where the user can select the school in one combo box and then it will give a list of the sports programs in another combo box.
One of the most important pieces of information and I definitely had a brain-fart on that one. I am really sorry about this!

You can do this with two XPaths, one that get's the name of all schools, and another to apply to the XML using the school selected to get a group of nodes that contain the sports for that school.

Hello all!
I have been searching for days, and days, on what seems to be a somewhat complicated and confusing matter: Passing a C++ STL Map (with a user-defined struct type) to C# via interop services.
First off, I am fairly new to C# and the world of Windows programming so that keeps me stumped on many articles I have read. I have explored some COM concepts, as well as simply using P/Invoke, but have yet to find something that works.
Is there any way to do this in a manner that is fairly straight forward? Does anyone have any examples or tutorials I can go by?
Basically what I want to do is call a C++ method (probably through p/invoke) and that method will return to me an STL Map (or vector) with a user-defined struct as its type. I need to be able to iterate through this collection pulling out each struct field and examining it.
I am stumped...
Thanks for all your help, I really appreciate it

Button box have Parent property Which you Can You Set it
To TextBox So You May Write Sothing Like This
private void textBox1_Enter(object sender, System.EventArgs e)
{
button1.Parent=textBox1;
button1.Location=new Point(textBox1.Width-Button1.Width,0);
}

Hi there!
I have a problem. What i want to do, is opening a remote file on the internet (a xml file) for reading in my application. The remotehost is not running any serving functions, the file is just available on the internet.
Is there anyone who knows how to do this?
Thanks in advance!

I wrote an article regarding this issue. The only major drawback is that this method doesn't function in all windows versions...

Erhm. Thanks for taking the time to reply to the topic, but that was a link to a article regarding "ExtendingFileDialogs"

You can use the HttpRequest class to request the file.

If I open the openFileDialog, usually I must select the view to "Details" manually. How can I automate that ?

I'm making use of a datagrid, How do you get the current value of a specific cell (row 0, col 0) after the user sorts by clicking on the columnheader? This is what I tried using the MouseUp event but I seem to be getting the value of the cell before the sort.
private void dGrdFamily_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
//if left mouse is clicked
if(e.Button == MouseButtons.Left)
{
Point pt = new Point(e.X, e.Y);
DataGrid.HitTestInfo hti = this.dGrdFamily.HitTest(pt);
if(hti.Type == DataGrid.HitTestType.ColumnHeader)
{
this.textBox2.Text = this.dGrdFamily[0,0].ToString();
}
}
}

If the DataSource is a DataTable you can use
private DataRow GetDataRowAt(int index)
{
DataRow dataRow = null;
CurrencyManager currencyManager = null;
currencyManager = (CurrencyManager)this.BindingContext[this.dataTable];
if ( currencyManager != null )
{
dataRow = ((DataRowView)currencyManager.List[index]).Row;
}
return dataRow;
}

Hi:
Thanks for your help. I tried your suggestion but I came across the same problem. It seems like the MouseUp event that I'm using may not be the best event to use in this case. It seems like it is obtaining the row value prior to the actual sort of the datagrid values.
Do you know of any event that I can implement to notify me when a change has occurred in a cell/row value (not change in row index)??

Use the datagrid.Refresh() function...

hi to all,
witch reference do i have to add to see the flexgrid and hierarcical flexgrid control in my toolbox
best regards and thanks in advance

Flexgrid last shipped with Visual Studio 6 (old school). It doesn't ship with VS.NET (same deal for heirarchical flexgrid, I think). If you want to write apps with it you have to fork out for the license for VS6, install the old VS on your dev machine with VS.NET and access the controls using interop.
I miss it too. So lightweight. So easy to code against...

open a new project
select class
type in your code
make sure the functions are public class
bulid ths solution
save the project
close the project
open your project
use the Using to call the dll
like
using projectdll;
create a reference type like
