I would like to thank the group for there responses. The responses were quite educational for me as I am still learning C#.
I plan to solve the problem by using the sort command that comes with the package cygwin. As it turns out, the key is always in the range of 0 to 1 so I can treat it as a string.

Hi,
I'd like to maintain of list of frequently used folders, something similar to the list of frequently used programs in Start Menu. Is there any way to find get some kind of notification when a user opens a folder using Windows Explorer?
|

|

You may be able to get that info through shell extensions, but more likely you'll have to find out what even is triggered within explorer (using Spy++), and then somehow hooking that event in your own app.
EDIT ===============
There is the FileSystemWatcher object, but I don't think that will let you know when someone is merely browsing a folder...

It won't track simple "reads / opens", but you can use the FileSystemWatcher class to monitor file and folder changes, creates and deletes.

Hi World of CodeProject!
I am writing a userControl(in C# coding) and I added some new Properties to it, Now my question is that :
How can I group this properties ,(Same as .Net that group it properties for each control)
|
|
|
|
|
If you mean grouping them in the property grid then you can use the Component[^] attribute
|
|
|
|
|
No I mean like Size it has to properties in it --->width,Height
|
|
|
|
|
the Size property is a struct, i.e. a composite type. That's what causes its members to be grouped.

How can I get HTMLDocument of an URL? I need to get HTMLDocument from a bulk url. I think I can't use WebBrowser because it needs to wait until the document is competed.
|
|
|
|
|
you can use WebBrowser.Document, which is available when the document is complete, hence look for the WebBrowser.DocumentCompleted event.

I know the webbrowser. I'm looking for another way, maybe download it as a string and convert it into HTML document?

I want to build something like this
http://www.codeproject.com/KB/aspnet/ChatApplication.aspx
However when using the example I try to build the chat app and get the error
Error 1 Inconsistent accessibility: parameter type 'ChatClient.IPAddressInfoEventArgs' is less accessible than delegate 'ChatClient.Configurator.IPChangeHandler' \EasyTalk\ChatClient\ChatClient\Configurator.cs 15 30 ChatClient
Any advice or examples of how to build a simple chat application using a web service.
Every google search presents many examples with very little explanation.
thanks for any advice

The compiler error means a parameter has a type that is less public than the method/delegate referring to it. Making the type (IPAddressInfoEventArgs) public (or the method/delegate not public) should solve that.

Hi,
Maybe it's an unusual request, but I need a practise (just defining a practise not any source code) that I use silverlight with WCF and WWF, for learning them better.
Best wishes

Do you mean that you want an idea for a sample application that you could use with WCF, Silverlight and WWF? If so, how about a simple stock ordering process?

That's exactly my mean!
Sorry,I was wondering if you give me or refer me more details
Best wishes

Oh, so not only do you want us to give you an idea for an app you can write in order to learn silverlight, you want us to write the code, too?
C'mon, be a programmer and just do it.

Oh, sorry
I just meant more details about the 'Stock Order Process' , not technical ideas about WCF,WWF , ....
anyway thanks for your time
Best wishes

Well, you could use WCF to simulate the ordering of items from a supplier. Use WF to control the process of orders when they come in, and the rules surrounding when orders should be placed, e.g. order this when an item goes below x. Finally, use Silverlight to maintain the details of items, and buy things so that your ordering process actually gets triggered.

It is best to use a sample that you understand, try a bug tracking workflow, something with escalations, email alerts and feedback to the initiator.

hi guys...i have a combobox on my form which is named as cmbfirma...and i fill it with a column of database..and i want user to add new firm if it doesnt exist in my database that is why i open new form and user writes new firm name to textbox and program writes new firm name to a txt file and i read it from there...and try to write that new form to my database..to do that i use code below
cmd.Parameters.AddWithValue("@firma",cmbFirma.SelectedItem.ToString());
but when i use it and check my database it writes there System.Data.DataRowView
and i tried another code below
cmd.Parameters.AddWithValue("@firma",cmbFirma.SelectedValue.ToString());
in that time it writes database normally only for the items which is listed in combobox and it gives error if i want to add the new firm name that i read from txt file...in error it says "Unable to set an object reference to an instance object"
what should i do to get rid off that errors ??
or should i use another database for my combobox ??
i use SqlExpress 2005 to create my database
thanks for your help

hey man thanks for reply ...i created the cmd object like below
SqlCommand cmd; (i declared it global)
cmd= new SqlCommand("select distinct firma from Rehber", con);
and my SQL sentence is like that and i insert like below
cmd = new SqlCommand("insert into Rehber (ad_syd,firma,sektor,grup,cep_no,is_no,ev_no,fax,mail,web,msn,skype,adres,ilce,sehir,vergi_no,vrgi_daire,dgm_tarih) values (@ad_syd,@firma,@sektor,@grup,@cep_no,@is_no,@ev_no,@fax,@mail,@web,@msn,@skype,@adres,@ilce,@sehir,@vergi_no,@vrgi_daire,@dgm_tarih)", con);
cmd.Parameters.AddWithValue("@ad_syd",txtAdSyd.Text);
cmd.Parameters.AddWithValue("@firma",cmbFirma.SelectedValue.ToString());
cmd.Parameters.AddWithValue("@dgm_tarih", dateTimePicker1.Value);
cmd.Parameters.AddWithValue("@sektor",txtsektor.Text);
cmd.Parameters.AddWithValue("@grup", txtGrup.Text);
cmd.Parameters.AddWithValue("@cep_no", txtCep.Text);
cmd.Parameters.AddWithValue("@is_no",txtisTlf.Text);
cmd.Parameters.AddWithValue("@ev_no",txtEvTlf.Text);
cmd.Parameters.AddWithValue("@fax",txtFax.Text);
cmd.Parameters.AddWithValue("@mail", txtMail.Text);
cmd.Parameters.AddWithValue("@web", txtURL.Text);
cmd.Parameters.AddWithValue("@msn", txtMSn.Text);
cmd.Parameters.AddWithValue("@skype", txtSkype.Text);
cmd.Parameters.AddWithValue("@adres",txtAdres.Text);
cmd.Parameters.AddWithValue("@ilce", txtIlce.Text);
cmd.Parameters.AddWithValue("@sehir",txtSehir.Text);
cmd.Parameters.AddWithValue("@vergi_no", txtVergiNo.Text);

hi,
you wrote:
"cmd.Parameters.AddWithValue("@firma",cmbFirma.SelectedItem.ToString());
but when i use it and check my database it writes there System.Data.DataRowView"
But the ComboBox control SelectedItem property returns an object! NOT a DataRowView.
If you need the selected item from the combobox you should use:
cmbFirma.SelectedItem.ToString();
or try this:
cmbFirma.Items[cmdFirma.SelectedIndex].ToString()
Do you correctly data bound the ComboDox control ?
Anyway, it seems that you don't have a problem with the combobox!
Try to verify better the code.
You have many parameters and maby you switch someone of them..
Cheer's,
Alex Manolescu
