String to Object?

Hi:

Can I convert a string to an object?

In my system I have the following:

Document.Title.Contains("Sony Camera")

The above returns an object of type Criterion, however, it will be saved in database,

when i read the above line as string, i want to make it an object of type Criterion, is this possible?

thank you.

Hi

(objectName) Document.Title.Contains("Sony Camera")

or

object.parse(Document.Title.Contains("Sony Camera"));

Hi

Thanks for the reply.

Don't I need any reflection? Just guessing.

Thanks,

This is what Request.UserAgent returns for Mozilla Firebird:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007
Firebird/0.7

Is there any reason why this shouldn't work to identify a visitor using that
browser?

If String.Compare(Request.UserAgent, "firebird", True) = True Then
[code]
End If

Using Mozilla Firebird, it jumps right over it. As a test, I replaced
"firebird" with "msie," and it catches the IE browser with no problem. So
why not firebird?

I can't use browser name or browser type because it returns Netscape, not
Firebird.

Thanks,
GeorgeI think you want String.IndexOf, not String.Compare.

Thanks, Eric, that did work. At a loss as to why the other one didn't work,
though.

String.Compare looks to see if the exact string matches (with or without the
case-sensitive flag).

The string "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5)
Gecko/20031007 Firebird/0.7" is not an exact match for the string
"firebird".

String/Number manip.

In the following line:
txtWage.Text = "$" & Trim(dataReader.GetValue(9).ToString)

It returns $20.0000 I only want it to return back $20.00 -- every search I've done in string manip. has shown me zilch.

Any suggestions?

txtWage.Text = Format(CDbl(Trim(dataReader.GetValue(9).ToString)), "currency")
I think you can use String.Format also to do the same thing, with the format of {0:c}

Strongly Typed Collections

I'm writing a web service that I want to return a strongly typed collection.
If I inherit System.collections.generic.list(of T) it returns an ArrayOfT.
If I inherit CollectionsBase, it also returns an ArrayOf. I want the root
xml element to just be of the class itself (if that makes any sense). Is
this even possible? What do I need to inherit?
If you want a strong object/collection on the outside world (of a web
service)...then the client needs to know something about some kind of strong
collection.
..
Take a look here:
http://sholliday.spaces.live.com/Blog/cns!A68482B9628A842A!158.entry
I have a IZebraCollection......which the service and the host know about.
Its WCF, but WCF can be exposed as a webservice.

Strongly typed datasets and nested repeaters

I have a strongly typed dataset that returns two tables - "items" and
"itemdetails". In the strongly-typed dataset designer, I've created a link
(relationship) between the two tables based on a foreign key.

I want to put them into a nested repeater, but I'm having problems finding a
"nice" way of doing it.

Can someone please point me in the direction of a tutorial or best practice
to achieve this?

Thanks in advance,

Duncanassign the "Items" table to the outter repeater, then in the
OnItemDataBound event handler:

switch (e.Item.ItemType){
case ListItemType.Item: case ListItemType.AlternatingItem:
Repeater ir = e.Item.FindControl("rptInnerRepeater")
ir.DataSource =
((DataRowView)e.Item.DataItem).CreateChildView("ItemDetailDataRelation");
ir.DataBind();
}

hope that helps
Thanks for your reply; I saw this example on the web, but I'm unsure where
the ItemDetailDataRelation comes from. I tried all the relationship names
that were in the strongly-typed dataset designer, but they gave an error.

I got the impression that if you were doing it between two datatables, that
would be the name of the Relations.Add(... but I couldn't seem to create a
programatic relationship between two fields in a strongly typed dataset.

The relation is set up in the dataset.

something like
_myDataSet.Relations.Add("Users_Results", _myDataSet.TableA.UsersNameColumn,
_myDataSet.TableB.UsersNameColumn);

where _myDataSet is your strongly typed DataSet.
in your nested Repeater you would then do something like this:

<asp:repeater id="_reportoutput" Runat="server"
...templates

//nested repeater
<asp:repeater id="_nextstuff" Runat="server" DataSource='<%#
GetChildRelation(Container.DataItem,"Users_Results")%>'
with the following in your code behind:

public static DataView GetChildRelation(object dataItem, string relation)
{
DataRowView drv = dataItem as DataRowView;
if (drv != null)

return drv.CreateChildView(relation);
else
return null;
}
