Did you try searching Google[^] before asking your question?

I was wondering if anyone had code to read contents inside an .iso file?
I am toying with the Nero SDK now and maybe it can do it. However, until then if anyone can suggest a way to do it I would be greatly appreciative.
Enjoy your weekend.

Are you still having trouble with this?

Yes I am. I have been googling and have came up with a few programs that do what I want to do. However, I would like to do this on my own..for learning purposes.
The main thing I am trying to accompolish is being able to view an iso's contents and display them in a listview. I already have an application that will extract an iso, just not view its contents.
Thanks for the reply and time.

How it is possible to convert from a base-class:
public class Test : Object
{
....
}
....
Object obj = new Object();
Test test = (Test)obj;
|
|
|
|

You can't do this. Object is the base class and Test the subclass. The Object type knows nothing about the Test type, so you can't create a new instance of Object and cast to Test.
Creating a new instance of Test and casting to Object is OK because Test derives from Object and therefore inherits its attributes and behaviour.

Object obj = new Object();
Test test = new Test();
test = (Test)obj;
Now I have an InvalidCastException
System.InvalidCastException wurde nicht behandelt.

How is this different to the code in your first post? It still won't work, for the reasons I outlined earlier.
I suggest you get a book on OOP and start reading.

Hi

1. how can i pick some record in datagrid ?
2. how can i do that my program will open only one time ?
3. how can i send mail with Outlook in c# code ?
Thank's

I'll tackle part #3. Everything you want is in the System.Net.Mail namespace. Believe it or not, there's a web site dedicated to this namespace:

Google SharpZipLib for information and code to use zip with c#.

Good ol' pie, it's been a while.

Be more specific. What is the trouble you are having?

Yes, it is. Read the following article: http://www.codeproject.com/dotnet/passingvaluesbetweenforms.asp[^]
You should be able to pass the datagridview object using the methods the author talks about.

Then what is? The article shows how to pass values from one form to another. You can extend this by passing the whole object from one form to the next using the same principles that Colin talks about.

I am not being harsh, but it sounds like you've bit off more than you can chew at this point.
You could always make the datagridview object be public and just grab it from the second form.

hi all,
im now doing the 'SearchEvent' using asp.net & C# on visualstudio2005,
where the user will search the event by selecting from the 3 dropdown boxes:
dropdownDay, dropdownMonth and dropdownYear.
It's suppose to query the 'start_date' from the ms access.
eg. 10-Mar-2004
im trying to write the query on it, but i kept getting the error when i run.
query:
string query = "SELECT code, description, start_date, start_time, venue FROM Event WHERE start_date = '" + dropdownDay.SelectedIndex.ToString() + " + ' - ' + " + dropdownMonth.SelectedIndex.ToString() + " + ' - ' + " + dropdownYear.SelectedIndex.ToString() + "' +";
Error message that appeared in visualstudio2005:
Syntax error (missing operator) in query expression 'start_date LIKE '%10 + ' - ' + 3 + ' - ' + 8%' +'.
i would appreciate some help on this line of code.
thanks! =D

your query is looking wrong
try this one
string query = "SELECT code, description, start_date, start_time, venue FROM Event WHERE start_date = '" + dropdownDay.SelectedIndex.ToString() + "' - '" + dropdownMonth.SelectedIndex.ToString() + "' - '" + dropdownYear.SelectedIndex.ToString() + "'";
