If your application has opened this file then you should close it properly by calling the Close() method of a stream so that other processes (as well as yours) can access it.
If you need to force file delete then you will need to close all open handles to this file. Here is a link which describes how to do it. You will need P/Invoke to port it to c#

Also, when you "force" the file to be close, don't be surprised when the process that opened it crashes...

My same thoughts. I don't know why he wants to delete a locked file in the first place. Sounds potentially dangerous.

Hi people...
I know that exists a HelpProvider component... but I think that writing a pdf is much more comfortable than 1000 topics (with related 1000 .htm pages)!
Is there a way to open a pdf file at a specified index? Or HelpProvider gives other possibilities instead of chm or htm files?
If I do have to create a htmlhelp file, which editor do you suggest?

People expect help files to be CHM or HLP files, and to be honest it's easier for people to use the search facilities in help files. Anyway, I like HelpScribble[^].

if i want to delete the selected row in a list view i use:
if (listView1.SelectedItems.Count > 0)
{
if (MessageBox.Show("Vill du verkligen ta bort denna?", "Mina jobb",
MessageBoxButtons.YesNo, MessageBoxIcon.Question)
== DialogResult.Yes)
{
for (int i = listView1.SelectedItems.Count - 1; i >= 0; i--)
listView1.Items.Remove(listView1.SelectedItems);
}
}

It's your course assignment not ours. I'm pretty sure the point of the assignment is for "you" to figure that out rather than for you to go out on the internet and ask people how to do it. I mean really, you are in school now, if this is not the time when you are going to start thinking for yourself and developing problem solving skills, when are you?

Hi,
my c# project includes an embedded resource called "driver.resources", which contains a driver called "test.sys".
A read alot about extracting txt/bmp/ico files, but i can't figure out how to extract my test.sys driver.
Any suggestions?
Thx in advance, knack

This article will help you to do that: http://www.codeproject.com/csharp/SlideShowBuilder.asp

This article also deals only with images, but how can i extract a file independent from its file type?
I want to extract my test.sys driver.

In that case have a look at my another article: http://www.codeproject.com/useritems/mp3toexe.asp

Hello
I search a map control that can display ECW maps with latitude and longitude coordinates. I can also pay something for this control.
Thanks for helps

Yes but they can't display ECW files. I must have a control that displays maps in ECW format.
PS: Thanks for the reply!

Hello,
On a lot of websites now, you can just enter your house number and postcode and it will bring up the rest of the details. Well, i want to implement this into one of my projects.
Does anyone know what this is called? and if so, is it free to download?
Regards,
Gareth.

Downloading something is unlikely as you'll need a regularly-updated database of postcodes and addresses. As you said postcode, I assume you want details for the UK, so Royal Mail provide all this information, but not for free.
There are companies that provide web services to do what you want, again unlikely to be free.
Try here.[^]

Hi Craster,
Since this is a personal project, i don't want to pay for something that isn't critical but useful.
Thanks for the reply.
Regards,
Gareth.
