XPath Select An Attribute Based On Value?
Mar 26, 2010
Using VB.Net,I have an XmlNode object, xNode.I need to select an attribute of this node if it has a particular value.
e.g. xNode.SelectSingleNode(".[@attr1='1']")
I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set.When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']")It always returns Nothing, even if the attribute has a value of 1.

I want to list all the true results in a form which the user is then able to navigate through. What would be the best way to go about doing this?

I have a table and I need to select the record based on an Id. I only want to return the record that has the Max(Date) on a date field. How do I do that?
In SQL Server I use this
SELECT * FROM dch
WHERE EffectiveDate = (SELECT MAX(EffectiveDate) FROM dch
WHERE ID = 99) AND ID = 99
How can I do this in Linq. Unfortunately this app is coded in VB.NET as we inherited it that way.
I was trying these
Dim qry = (From dch In db.dch _
Where dch.Dealer.Equals(Dealer) _
Select dch.EffectiveDate).Max()

What I have is 4 datagridviews named dgv1, dgv2 etc.I also have a variable curr_player whose value is between 1 and 4. I would like to be able to enable one of the dgvs based on the value of the curr_player variable. I'm reluctant to to write select case for each time I want to do this so the question is can I enable one of these objects based on that variable?

I'm trying to write a small app which can be used in order to log off Citrix Sessions. Citrix Sessions can be logged off via cmd or a batch file using this method:
[Code]...
So basically what I want to do is to select each listbox item that matches one of the hits from the cmd command. Probably the servername that gives a different result than "No User exists for" How can something like this be achieved?

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table.
I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum.
Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum

Contact Title has a default value which is Sales Person. Anyhow, when a user click Edit on the chosen ListView record, i need Contact Title to have the right value that corresponds to the chosen record. For example, if user clicks edit, the fields on the left side will be filled with values. In this case, i want Contact Title to view the right value.
