hi guys
i have a class named abc_voucher and another class
derived from abc_voucher named def_voucher,
but in my application i have a function and its return type is
generic list of abc_voucher and i am returning from this function the generic list
of class def_voucher which is derived from abc_voucher , but it gives an comlite time error ,,
though my return object is derived from the type which i am returning in function's signature ,
why is that ?
thanks in advance

Are you extracting the def_voucher list from the list that you retrieved that has the abc_voucher list? Is that what you're doing?

no i am not extracting
def_voucher is derived from abc_voucher , but it gives compile time error
public function abc as list(of abc_voucher)
dim list as new list(of def)voucher)
'
function body
'
return list
end function

Hi,
Sorry to tell you that, i am not getting what you are trying to achive appart from some class relation.
namespace CS<br />
{<br />
class Program<br />
{<br />
static void Main(string[] args)<br />
{<br />
B Obj = new B();<br />
List<A> _list =Obj.GetList();<br />
}<br />
}<br />
class A<br />
{<br />
protected int Age=0;<br />
public A() { }<br />
public A(int age)<br />
{<br />
this.Age = age;<br />
}<br />
}<br />
class B : A<br />
{<br />
<br />
public List<A> GetList()<br />
{<br />
List<A> GList = new List<A>();<br />
GList.Add(new A(21));<br />
GList.Add(new A(22));<br />
GList.Add(new A(23));<br />
return GList;<br />
<br />
}<br />
}<br />
}
Presumably, the above lines of code will give an idea on the route map.

That's because you can't upcast, only downcast.
So while you can add a def_voucher object to a collection of abc_vouchers, you can only interpret the contents of the list as abc_voucher objects.

That's because inheritance is a form of specialization of abstractions. Student is a special form of Person etc. You cannot specialize something general, but you can generalize something specialized.
This is analogous to saying "Every Student is a Person" [Generalization] But you cannot say that "Every Person is a Student"

Hi,
I have to read too many data from a web site using SOAP. For that I create a button and read the data.
I have to read the data in background (Automatically) which option is better...?
I use timer say after every 15 min that makes my app slower.
I also use background worker but it will give cross threading error because I have to update the content of the win form.
And one big issue is their are too many problems to connect with the web site like server unreachable, Connection failed, Invalid query, too big response from SOAP etc.... So I also have to handle that, So how can I resolve this..? please help me...

Not if you implement it correctly. See this[^] article.

Hi,
I am writing a Pocket-PC application in C#. This application requires data synchronisation, so I thought... nothing easier than that.. and developed a webservice.
But then, I thought it would be very nice to give the user a visual feedback what the pocket-pc application is actually doing... and I thought about a progressbar to display the progress of the synchronisation process.
so far so good....
I wrote a SoapExtension for my webservice and tested it in a win-form application.. works great BUT
i have to provide a little snippet to my app.config file like:
< system.web >
< webServices >
< soapExtensionTypes>
< add type="TimeSheetApplication_FORM_test.ProgressExtension, TimeSheetApplication_FORM_test" priority="1" group="0" / >
< /soapExtensionTypes >
< /webServices >
< /system.web >
but a pocket-pc application doesnt have an app.config. okay, fair enough I thought..
I wanna get this soapextension-sh*t into its own project anyway. So I created a new class project and moved the soap-extension over.
but then I got the following errormessage when compiling:
The type 'System.Web.Services.Protocols.SoapHttpClientProtocol' is defined
in an assembly that is not referenced. You must add a reference to assembly
'System.Web.Services, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.......
....
The system.web.services assembly is already referenced in both project.....
has anybody consumed a webservice on a pocket-pc application via soapextension yet? and if yes, how did you tell the pocket-pc application to use the soapextension without providing this information in the app.config?
any help or suggestions are very appreciated!!!! ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

hi guys,
the solution is to create a class which is inheriting from SoapExtensionAttribute.
After that you set a attribute on top of the method you are calling the webservice and suddenly your soapextension gets invoked as well.
easy - if you know it

Alright, well i am working on a desktop application. I am trying to figure out how to create child nodes under the root. I have tried almost everything, and the closest i get to the solution is creating a child node that looks like this:
<Root>
<whatever name="something />
</Root>
when in fact i want
<Root>
<whatever name="something>
</whatever>
</Root>
Also, how can i place more child nodes under another child node once created?
Thank You

These 2 XML fragments are functionally equivalent:
<whatever name="something" />
<whatever name="something"></whatever>
If you want to add inner text to the <whatever> element, do this:
XmlNode whateverEle = ...;
whateverEle.InnerText = "some text";

Is there a way for me to pass multiple variables in a constructor with a single variable, why because I will be repeating this process many time. Also have a definition for the constructor variables. See the following example:
PassVariables = {a, b, c)
ConstructorVariables = {this.A a, this.B b, this.C c)
Thanks in advance,
Michael

You could have all of the variables you want to pass inside an object that you pass through the constructor. There are many ways this can be done.
