Hi,
Here what I mean is how to implement Heirarchical Strcutures and Tree Diagrams to show data in .Net framework.
There is an ActiveX Control VARCHART XTree from NETRONIC Software, but does anybody know how to implement Heirarchical Strcutures without using any ActiveX Control.

ddinesh,
.NET doesn't supply a control if thats what you want. You will have to write your own implementation or get a 3rd party (www.yworks.com). Theres also examples on here, have a search in the articles section.
Regards,
Gareth.

Hello, I have the need in my project to add a "print-a-report" utility using Crystal Reports and the end-user must be able to customize the report's design visually, much like Visual Studio allows the developer to do.
I don't have any experience with Crystal Reports and I was wondering if there was any (free) component or something to allow the end-users to change the appearance of the document or if building it oneself is the only option available, cuz I didn't find anything googling around.
Thanks in advance.

Thanks, but that's not quite what I need; this only browses through the properties of the instance itself, while I actually want the end-user to visually edit the appearance of the report using some kind of designer tool, just like Visual Studio or Access when you open a report with it.

If you are using SQL Server 2005 or above, you may want to take a look at Report Builder[^]. It is a component of the suite, in the form of a ClickOnce application that is intended for allowing end users to create/customize reports on SQL Server Reporting Services. A google search will net you a bunch more information.
Hope that helps to get you started.

Why, that's interesting, didn't know about it, thanks. Alas, that's not exactly what I'm looking for.
I don't want the user to actually "generate" the report itself (the data will always be the same), but rather to be able to edit just the appearance of the document to print, so they can create and select multiple report "models" or "styles" once the report itself is already generated.

Can any one explain me how this licensing is done. i mean how do we generate the key and use it in the software. it would be of great help if any one can explain me this process in detail.
thank you

Depends entirely on you. There's plenty of obvious ways to do it, from the simple way of hard coding the license key in the program and checking if it matches, to using an algorithm to check if the key entered is valid, to using online licensing to validate a machine as being a valid license.

I'm currently using DateTime.TryParse() on a text field with the format DD/MM/YY. I noticed that the default behaviour of TryParse() was rather fortuitously turning 08 into 2008. Which got me thinking (apart from - next time I'll use a field with YYYY) - how does TryParse decide which century to use? I can't find anything on MSDN, and an initial Google search turned up nothing. Can anyone satisfy my curiosity and tell me the "rules" that are used? My gut feeling is that it's tucked away in the Culture settings somehow...

Why not download Reflector and find out for yourself? This is a fantastic tool that is invaluable if you want to find out how things work rather than just accepting that they do.

More a general hint that there are other options. Sure - read the documentation, but don't accept that it's right - actually research for yourself. After all, the MSDN is well known for its accuracy and consistency.

Thanks for taking the time to have a look - I didn't find/see a link to this documentation in the msdn documentation on TryParse(), but unfortunately this documentation doesn't answer my initial question. When I get a little time today, I will attempt to follow Mr O'Hanlon's suggestion. (I have avoided Reflector in the past as it seemed a bit scary)

DateTime.TryParse() has an overload that takes a IFormatProvider parameter and puts you
in charge of what is acceptable and what is not.

Everyone must have used Gtalk..

Nope. I haven't.

I assume that this is implemented by creating a NotifyIcon control. Use a timer that fires periodically, checks to see if there are any messaged and updates the NotifyIcon.Icon property accordingly.

I'm in need of some assistance i finish creating an DataGridView and it gets DirectoryInfo from the desginated Directory
my code looks as following:
private void ReceivedFiles_InitColumns(ref DataGridView value)<br />
{<br />
value.Columns.Clear();<br />
dgv.AutoGenerateColumns = false;<br />
<br />
DataGridViewTextBoxColumn col = DataGridView_CreateColumn();<br />
col.DataPropertyName = "FullName";<br />
col.Name = "Naam";<br />
col.ReadOnly = true;<br />
value.Columns.Add(col);<br />
<br />
DataGridViewTextBoxColumn col1 = DataGridView_CreateColumn();<br />
col1.DataPropertyName = "extension";<br />
col1.Name = "Extensie";<br />
col1.ReadOnly = true;<br />
value.Columns.Add(col1);<br />
<br />
DataGridViewTextBoxColumn col2 = DataGridView_CreateColumn();<br />
col2.DataPropertyName = "LastAccessTime";<br />
col2.Name = " Laast Gebruikt";<br />
col2.ReadOnly = true;<br />
value.Columns.Add(col2); <br />
}
Tough now i need when i select and item from the DataGridView that i can remove an entry.
i already tryed :
private void btnDel_Click(object sender, EventArgs e)<br />
{<br />
dgv.Rows.Remove(dgv.Rows[dgv.RowCount -1]);<br />
}<br />
but that doenst work because i need IBindingList
if someone know how to get and remove entry function or some advise on how i could change my code so it works i appricate it
Thanks in Advance

foreach (DataGridViewRow selectedrow in dgv.SelectedRows)
if (!selectedrow.IsNewRow)
dgv.Rows.Remove(selectedrow);
This will remove all the selected items.

I think you're getting an error because you're trying to delete the new row which is the last row.

Thanks for helping,
I used it and ran an quick test i keep getting the IBindingList error
Is there an way that i can create or connect IBindingList to my DataGridView code?

You're welcome.
How are you filling the data? Can you provide more information about the exception? If possible, post all code related to this DataGridView.

<br />
}<br />
Thats everything releated to the datagridview.
the // parts are what i already tryed but i get the IbindingList Exception

That's where everything goes wrong. You're binding the grid to an array. Arrays do not impliment the IBindingList interface.
You should put your data in a data structure that implement the IBindingList. You should put your data in a DataTable and then use it as the DataSource of the DataGridView.
