Yes it does. Don't be rude. As I have already written RegistryValueKind.MultiString needs an array of strings. What you are passing is collection of objects. In my opinion you should create an array of string which will contain items from listbox and pass it to SetValue. Hope it helps

Appologies if I sounded rude but I was not being rude at all. I am not very good at explaining things sometimes so I was genuinly asking if my description was confusing or not.
Thanks for your comments I will try it out now.

You can include have filesystemwatcher that looks at a directory and its subdirectories. If you need for different directories, then you will need several filesystemwatchers.

Thankx for your reply.
Is there any other way for multi folder watcher except add as many fileSystemWatcher as many folders that I want set watcher???

The settings are saved.
It is saving in the folder:

But I want to Store the user.config file in the Location that I Specify.
How can I do this?

I've made an inherited ListView control with a customized ColumnHeader Type.
I've overwritten the Columns property with a collection of my custom
ColumnHeader items. Now I would like to implement serialization so that
columns are persisted from designtime to runtime. But I cannot get it to
work.
I think it's because I don't know how to implement the type converter
correctly. Here's my suggestion for the type converter. Sample code for the
ListView, ColumnHeaderCollection and ColumnHeaderItem is supplied below. Can
anybody tell me what's wrong?
I've got a small test project (C# 2005) that I've stripped of everything but
the important part (the collection) - I cannot get the serialization to
work. I add columns at designtime, but no matter what, the columns are not
persisted to runtime. If anybody has got the time to help me, I can mail the
test project. I would REALLY appreciate any help I can get.
Cheers, Johnny J.

i have a .net(C# + asp.net) web application that needs to show a set of log files on the browser once the user is logged in. The user should be able to download the files by clicking or right click->save as.
any ideas or samples will be thankful.

Here's[^] a sample that shows you how to do this.
Deja View - the feeling that you've seen this post before.

thanks for the reply.
I think the sample you mentioned will directly downlaod all the files without any selection.
i want the user to click a file and then download.

i mean i want the files names as a kind of links on the web page.

To do this, you need to build the list of links yourself, and dynamically attach an event handler which handles it in the same way that the button click does in the article.

What do you mean "loop the label or textid"?
The code you have written puts the value of the first column of the first row in the Text property of the text box. It won't loop over anything.

|
|
|

textboxname.text=cmd.executescalar()
ExecuteScalar returns object.
You assigned this object to var string so that u r getting error here
try this code
textboxname.text=cmd.executescalar().ToString();
Best Regard

And if the result set contains zero rows this will fail also.

Hi All...
I work for a software development company which writes Telephony solutions.. All of our backend components are written in C++ but the problem I am finding is it is taking us to long to get products to market and am looking for a quicker means of writting these applications.. I have been researching and toying with the idea of moving some of our newer products to C# to try and improve stability and simplicity in our applications. The only thing I am unsure about is the performance aspect and if C# can do just as much as C++ can. We use Threads, Handles and pointer list's extensivly. These applications are real-time applications and need to perform task's quickly and efficiently without delay. Maybe I am asking to much of having the best of both worlds but any advice would be appreciated..

A common misconception is that C# cannot work with pointers. This is not true. While it is not recommended to work directly with pointers, you can do it by marking regions of code as unsafe, so you could move highly intensive pointer based code into these areas. I would question though, whether or not this is a route you would want to go down when you can mix C++ and C# projects in the same solution.

hi all,
I have a xml file of the following format.
<xml version="1.0" encoding="UTF-8">
<MainCategory>
<category1>
<title>First Title</title>
<Description>Some description</Description>
</category1>
<category2>
<title>Second Title</title>
<Description>Some description about the second category</Description>
</category2>
</<MainCategory>
</xml>
the data from the xml file is stored in a datatable and set as a datasource to datagridview.
now when a new entry is added to the top of the xml file, say like this,
<xml version="1.0" encoding="UTF-8">
<MainCategory>
<NewCategory>
<title>New Title</title>
<Description>description about new category</Description>
</NewCategory>
<category1>
<title>First Title</title>
<Description>Some description</Description>
</category1>
<category2>
<title>Second Title</title>
<Description>Some description about the second category</Description>
</category2>
</<MainCategory>
</xml>
how can i check the xml file for new changes and display the values for the new categories alone?
this xml file is not stored in the local machine. how can i accomplish the same without storing the xml file locally?
Thanks in advance.
Regards
Anuradha
