If your server have a static IP, you can use that
|
|
|
|
|
it does not have a static ip
|
|
|
|
|
AFAIK, it requires a static IP to connect. ALternatively you can create a webservice and map it with a domain name, make your application contact to this webservice, and webservice to your database which is in same server.

Hi all,
I have a dropdown list on a c# webpage.
The page allows the user to select from a dropdown.
The page allows the user to click on a submit button after selecting.
Once the user selects and presses the dropdown, the system automatically refereshes the page and refereshes the dropdown to default state which doesn't allow me to capture the dropdownllst.SelectedValue.
Kinda frustrating, Any suggestions?
Thanks

Is viewstate disabled for your page ? Where you are trying to capture the selected item ?

It's a reference type. Value types are primitive types like int,char

And any user defined structs.

hi
i have created on class library project in c#.net 2.0. I want to add drop down list web server control in class library project in c#.net. But i have seen that System.Web.UI namespace is not supported in this type of project. But i have to add it anyway.
Anyone has idea or code to implement this.
Please help me out.
|
|
|
|
|
I'm not sure whether it works or not:
Try to make a custom control which wraps drop down list, and use it on your web server project.
|
|
|
|

i think u should add the refrence on ur project,then will see it

It's not clear to me how to specify a time in a DateTime object. I've read the Help files completely, but there's something basic I'm missing.
I know how to GET the pieces of a DateTime object (hours, minutes, etc). How do I *change* them?
At base, I want to be able to say "create a new DateTime object reflecting the Date Oct 5, 1945 and Time 1:07 PM, UTC".
Anybody?
(Modified, meant "object" not format.

Hi, DateTime type has many constructors, the following one is pretty general:
DateTime (Int32, Int32, Int32, Int32, Int32, Int32)
Initializes a new instance of the DateTime structure to the specified year, month, day, hour, minute, and second.

Thanks, Luc. There was a page in the MSDN after all - under the "DateTime" member of the "DateTime" class (I may never understand this terminology):
ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/cpref2/html/O_T_System_DateTime_.ctor.htm

You mean, kinda like this:
DateTime myTime = new DateTime(1945, 10, 5, 13, 7, 0, DateTimeKind.Utc);
?

My current favourite word is: Waffle
Cheese is still good though.

Yes, I was "baffled" by the word "constructor" in the help files, apparently. Oddly enough, there's no examples of creating DateTime in any of the examples and sample code. Just deconstructing and converting them.
Your favorite word is now "baffle", although "lennet" is still pretty good.

yes, also value types have constructors.
It is correct, but not very useful, to write int a=new int(7);;
it is useful to use constructors on structs, such as DateTime.

Yes, I'm way too used to using .Net objects without really understanding what they are. I see all these properties like DateTime.Hour which I can *get*, and I assume that I can *set* them, too.
Of course, the values in DateTime can only be set when they are initialized, but that wasn't occurring to me. So I was using new DateTime(), and trying to set the individual properties.
Intellisense would have shown me the constructors for "new DateTime(" if I had been paying attention, but clearly I was not.

This is a copy and paste from a post in the ASP.NET forum[^]. Are you aware that cross posting is considered rude by many people?

How do I run constructor without calling it's method's C# ?
for example:
class A
{
private static A _instance=new A();
private A()
{
SomeSingleTonClass.Instance.Items.Add(this);
}
public static A
{
get
{
return _instance;
}
}
}
thanks.

You might want to look at this implementation of a singleton: http://blog.colinmackay.net/archive/2007/09/05/393.aspx#395[^]
The version I have in the main blog entry is fine for single-threaded applications. The version in the comment is thread-safe.
Essentally you need to call the constructor in the public static property.
