View 1 RepliesImplement Yield Return For IEnumerable Functions?
May 17, 2009In C#, when writing a function that returns an IEnumerble<>, you can use yield return to return a single item of the enumeration and yield break; to signify no remaining items. What is the VB.NET syntax for doing the same thing?

DataGrid Columns Math - Result Return The Answer In The Unbound Yield Column For That Row Represented As A Percentage?
Sep 20, 2010I have a table in a data grid the columns are bound to the columns...
SQFT QTY WIDTH LENGTH
i also have added into the datagrid an unbound column called Yeild%.what i'm trying to do is the following formula
SQFT / (QTY * (width * length / 144) and have the result return the answer in the unbound yield column for that row represented as a percentage
So if SQFT = 178 QTY = 2 Width = 144 Length = 102 answer would be 0.87 (rounded)
so this would be 87%

.net - Identical If() And If Yield Different Results
Dec 22, 2010What is the difference in the two blocks of code below? I expected them to return the same result, but they don't.
In the case where xml.@Type = "null", I want PatientMetricTypeID (a nullable Integer) to end up being Nothing.
Block #1: If()
In this case, it ends up as 0. It looks like Nothing is being treated as an Integer and converted to 0. I can sort of see why this might happen but not fully... I would like to understand exactly how this works, and if there is a workaround.
Dim PatientMetricTypeID As Integer? = If(xml.@Type = "null",
Nothing,
CType([Enum].Parse(GetType(PatientMetricTypes), xml.@Type), Integer))
Block #2: If
In this case, it ends up as Nothing -- expected behavior.

C# - Way To Implement Caliburn-like Co-routines In Since There's No Yield Keyword?
Mar 26, 2010Note that I'm aware of other yield in vb.net questions here on SO. I'm playing around with Caliburn lately. Bunch of great stuff there, including co-routines implementation.
Most of the work I'm doing is C# based, but now I'm also creating an architecture guideline for a VB.NET only shop, based on Rob's small MVVM framework.Everything looks very well except using co-routines from VB. Since VB 10 is used, we can try something like Bill McCarthy's suggestion:

It definitely isn't as elegant as C# version, but it looks to be doable. We'll see if there are any problems with this. If anyone has better idea, I'm all ears.
Visual Studio 2010, Outlook 2010 And Windows Application, Return Emails?
Jan 5, 2011At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.
.net - Yield/Sleep/throttle Another Thread While It Is Executing A Method In An External Library - Specifically Jurassic?
Jun 25, 2012I am using a .Net JavaScript implementation called Jurassic to run user-controlled scripts within my .Net 4 WPF application coded in VB.Net - C# answers are fine. The script engine runs on its own thread and provides an API for the script to interact with my application. This all works really nicely until a user executes a script that causes an infinite loop and takes out a core of the processor.
[Code]...
The reason I care about keeping the thread alive is because the user who wrote the script and the user who is running it may not be the same, and I want to keep the experience as smooth as possible the the user running the thread. There also might be legitimate situations in which a single JavaScript function would run for a long time and I do not want to kill that, I just want to stop being allowed to hog the resources.
Solutions that involve stopping the thread from slowing down the system but that still show high CPU usage are not preferable because I do not want the user to wrongly feel that the application is resource intensive.

View 16 RepliesVS 2010 : Return Data From A Specific <div> Via A Web Request?
Feb 12, 2012I am trying to search for a term on this site: [URL] and return the definition of the term to a RichTextBox. I can search for the term easily enough. My initial idea was to find a div class similar to every definition, and in the source returned from my WebRequest there is always the div class:
<div class="luna-Ent">
So for example, if you search the term "lol" and view the page source, the definition for that term is wrapped as follows:
<div class="luna-Ent">laughing out loud; laugh out loud: used as a response to something funny or as a follow-up to something said only as a joke.</div>
My problem is that I cannot split the string, which contains the entire text from this web response, leaving just the above. Which I would further split to leave just the definition.Every time I attempt to split the string I get a bogus result with randomly cut up words and nonsense. There is only one <div class="luna-Ent">, so I have no idea why this isn't working when it does with a simpler string such as "lol?55?44" which you would split using "?".Here is the code so far, please excuse the crappy variable names. I always structure my stuff like that when testing?
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then
e.SuppressKeyPress = True
[code]....
Instead of my method, is there any way to return only the data, from the web request, wrapped in that div class?
VS 2010 Access Database + TableAdapters: Return Last ID?
Nov 15, 2010I am using an Access database (mdb file) and for the first time ever I'm connecting to it using a bunch of TableAdapters created in a DataSet.xsd file.I added an Insert query to a TableAdapter, and now I need to retrieve the ID (autonumber) of the last inserted record. Usually, I would send a "SELECT SCOPE_IDENTITY()" query and it would return the ID, but for some reason I cannot get this to work with the TableAdapter.
I tried two methods:1. Add the SELECT SCOPE_IDENTITY() query directly after the INSERT query in the TableAdapter. This method is described in every website I found by googling my problem. Suppose my INSERT query is this:
INSERT INTO Test VALUES("1", "2", "3")
then I should now modify it into
INSERT INTO Test VALUES("1", "2", "3");
SELECT SCOPE_IDENTITY()
I also changed the ExecuteMode to Scalar.
Ok, I run this code, but it doesn't work. It gives me an error saying Characters found after end of SQL statement.Is it because I am using Access and not SQL Server maybe? I dunno... But whatever I try it doesn't work. It's not a spelling error, and I did type the semicolon to separate the two queries so as far as I know it should work.2. Add a separate Select query (selected 'Select query that returns a single value' in the designer) that simply executes this:
SELECT SCOPE_IDENTITY()Then after using the Insert query I can simply call this query method and get the last Id. But unfortunately this doesn't work either. It doesn't even let me add this query in the designer, it says Unable to parse query text.
