Reading RDF - Data Is Stored In Triples: Subject, Predicate, Object?
Feb 17, 2010
After browsing the internet on how to read RDF Triples, the only things i came up with were user created libraries and so on. Some MSDN documentation on Microsoft's website confused me as well, as trying to import the Namespace shown was not possible. (Maybe it's possible just in C#? no idea).So how would someone read an RDF Triple using VB.NET? RDF is an XML format in which data is stored in triples: subject, predicate, object.
Example:
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:dc="http://purl.org/dc/elements/1.1/">[code]....

i have already implemented a solution of my own but it's too slow and i can't find any relevant literature on the internet.

S0P,A,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0 S0P,A,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
Here is the code:

I believe I have 2 problems. First, I have 1 program (VB6) that reads and stores emails from a department mailbox into a database. This program uses mapi and CDO. I have a 2nd program written in VB 2008 that displays the email information that was stored in the database. Everything works fine except the user now needs all formatting to be displayed ie highlighted, bolded text, etc contained in the email. The first problem is the email is stored in the database as plain text. I don't know how to get HTML formatted text from MAPI/CDO. Secondly, if I did store the email message in HTML format, would I be able to display in a .NET control on the form other than using the Web Browser?

well heres another issue i can't find a solution to. Look at this example
vb.net
Private Sub Button1_Click(sender As Object, _ e As EventArgs) Handles Button1.Click Button1.Tag = LblPlacer.MarginEnd Sub Private Sub Button2_Click(sender As Object, _ e As EventArgs) Handles Button2.Click Button1.Margin = Button1.Tag ' this is wrong huhEnd Sub
so how do i do this? what i am doing is as follows, when button1 is clicked the placer location is stored in button 1's tag property, this placer label is moved elsewhere by modifying its location in some manner. when i click button 2 then button 1 is moved to the location of the placer label when button1 was clicked.
As for solutions this is just an exercise within these constraints, i know i could set a global thickness and use this but i wish for this example to use the Tag Property as although storing onto the tag is easy and examples abound, I have found no examples of what to do with an object in a tag.

I am getting the following erro message: "Unable to cast object of type 'System.String' to type 'System.Predicate`1[System.String]'." on the line of code: If Not StrgFrag.Exists(wrd) Then I was expecting a True/False response and assumed it would work given that wrd is a String variables and StrgFrag in a List(of String). Do I need to reference the wrd variable differently? Dim StrgFrag As New List(Of String)

I have no chance to simple search a property in my property list by using the ".Title" of the property. Instead of using "For each > If .Title = SearchTitle" I prefer to do it with the Predicate and ".Find" methode.
Can someone help me to find out, how to avoid using the local variable " _SearchProperty" in the example below?
Private Sub NumericUpDownFrequency_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NumericUpDownFrequency.ValueChanged
Dim PropFrequency As F_SCANT30_DEVICES.TB.Devices.clsFscanProperty

My issue is to Find exact one Calendar object from a List Of(Calendar) by passing a particular date. I got to know about the predicate but not sure about passing parameter to it.

I got the predicate samples from Google and reached till now. But not sure how to pass my parameter i.e. date to it.

Having a bit of trouble using the List.Find with a custom predicate i have a function that does this
[code]...
by doing it this way means i have to have a shared "currentKey" object in the class, and i know there has to be a way to pass in the values i'm interested in of CurrentKey (namely, keyname, and oldkey) ideally i'd like to call it by something like keys.Find(AddressOf FindByOldKeyAndName(Name,OldVal))however when i do this i get compiler errors.How do i call this method and pass in the values?

I am pretty confused about lambdas. What I am trying to do here is write a function that will return an object from a certain table with a certain criteria. So lets say I can write:
function GetRecord(TableName as string,Criteria as string) as object
'do the linq-stuff
end function
Now I don't care if the parameters are strings or lambdas or whatever, but the end result must be that at runtime I don't know which table and which criteria will be used. As sometimes I need to get a customer record by email and sometimes a product by id etc. If possible I would prefer returning a list of matching objects and then I would just use .firstordefault when I want 1 (such as by id...).

I have a program that will download files from a company website given a list of links. The site requires authentication, and I do have code that will set the authentication cookie in the request header. I get the authentication cookie from a Perl script we have. What I would love to do is have my vb .net program get the authentication cookie based on my username and password. The perl script goes to the following link:

I'm trying to pass a business object from one WinForm to another WinForm for modification, and then repopulate the text boxes, etc. on the first form with the updated values.However, it seems that the object values set in the second form are not "sticking" when the code control returns to the first form.Is there a way to view the memory location of an object in VB.NET? I want to first make sure that the object variable on the second form is pointing to the same memory address as the object on the first form. Then I can take it from there.
In a separate VB project, I passed a simple object to a second form, modified the values, and re-displayed the object's values on the first form. It worked fine. In my real app, I'm passing an object that is a property of another object, which may be why it isn't working.SOLUTION: The problem was that I was using a DeepCopy() function that I found to simplify copying the properties of one object to another. Removing that function and manually setting the values to the passed object on the second form (ex. obj.property1

But this certificate doesn't have a "Subject Unique Identifier" Take a look at this:
[URL] (The part of Structure of a certificate)
And I want to know how can I read that value from my .NET code (I looked that I can get SerialNumber, Thumbprints and others but there is no Subject UID anywhere).
If anyone can share an openssl command to include this UID for the certificate :-) (pfx one)
