Hi! Is is possible to come up with a C# application that uses databases but doesnt really need to install Mysql or Oracle? I am using a windows platform and I need to come up with an application that if installed in another computer, wouldn't need to install a database also.
Thanks very much!

As far as 2-tier achitecture is concern, the answer is yes. You don't need to install your application together with the database. You can create an application in any language that can connect to a remote database server.

Did you mean "database server"?
If so, you could use MS Access or SQLite if your application can live with their restrictions.

You could also look at SQL express 2005. It's free.

Neither. A ListView control supports multiple selection.

Listview supports multi selection. This control is similar to the right pane of the windows explorer. There is a property in the listview control which is the 'Multiselect' and it is defaulted to True.

Yes you can also select a certain item if the MultiSelect is false. Clicking the items listed on the listview will automatically be selected. Ofcourse you can select only one in this case.
|
|
|
|
|
You can use this code to select the one item selected.
listView1.Items[listView1.FocusedItem.Index].Text

I don't know what "nn" is, but the rest of your question can be answered here[^].

Ah. There's a wealth of information out there on using ANNs to model weather forecasts, including this NOAA paper[^].
Sorry, I can't help you with specific code, although my interest in ANNs is in a similar space (financial trend analysis).

I have two Datagrids, one above the other with the same width and X starting point. Is there a way that when the horizontal scrollbar of one is moved right-left, the scrollbar of the other moves to the same position as well?
Thanks!

Handle the scroll event on one and set it on the other. If you do it for both, you need to set a flag to say it's autosetting, or you'll go into an endless loop.

Hello everyone:
What is the difference b/w
int x = (int)MyValue;
and
int x = System.Convert.ToInt32(MyValue);
which should be used when and why? Thanks.
We are using an automated tool for standard validation and its fussing about (int) way of type conversion, can someone plz explain the difference b/w the two. Thanks.

Hi Robert
Both ways do similar things, but it depends what the actual Type of MyValue is.
(int)MyValue is casting MyValue to type int. This means that MyValue has to be an int in the first place, or a type inherited from int (which isn't possible of course!). This is a faster method, because very little has to be checked or changed in memory, but you have to know that MyValue is actually an int.
Convert.ToInt32(MyValue) allows you to create an int from other types, e.g. a string like "56". This is useful if you aren't sure what type MyValue is. Because it has to work out what to do with the value tho, this method can be a lot slower than casting directly.
For more info, see MSDN:
Casting in C#: http://msdn2.microsoft.com/en-us/library/ms173105(VS.80).aspx
Convert Class: http://msdn2.microsoft.com/en-us/library/system.convert.aspx
Hope this helps

Some remarks and I would appriciate your input.
(int)Something conversion is applicable when Something is a numeric type. It just does the convertion without caring what data is lost.
I did sometesting and here is what i came across
string a1="5";<br />
int b1=(int)a1;
result in a compiler error
object a1="5";<br />
int b1=(int)a1;
result in runtime casting exception Error.

yes it is possible. But you need to have a SDK for your software. Are you reffering in VoIP? If yes, there are SDK available on the net that your can integrate in your software.
OR
You can create your own SDK by using your OS messaging and communication.
