Have you tried unsafe blocks?

You can call a function of class a using an object of class b type if class a is a base class for class b.

Hi to all,
I have one string "Ganges: River Of Life" & i want to replace ':' character with space. i have following code but it is not working.
str = "Ganges: River Of Life";
str.Replace(':',' ');
Anybody tell me why this happened?

The reason is that Replace function doesn't modify its parameter, it just returns new string so your code should look like this:
str=str.Replace(':',' ');

Yes.
Don't know.

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

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.

- use PRE tags to preserve formatting when showing multi-line code snippets
- before you ask a question here, search CodeProject, then Google

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):
