VS2010 Multi Line Lambda?
Jun 29, 2010
While reading an article by Deborah Kurata "Getting ready for VB10" under the section "Better Support for Lambda" she mentions using multi-line Lamba for debugging. So I tried it out on a class and worked just as she described (see figure 1). Now I am wondering if this can be done in regards to ForEach with a Dictionary as shown in figure 2. I am asking as when attempting to mimic the ForEach in figure 1 I get a message indicating there is no signature suitable for doing the multi-line Lambda statement for a ForEach
Private Sub Example()
Dim Taxpayers = New List(Of Taxpayer) From
{New Taxpayer With {

cartItems = cartItems.Select(Function(ci) New With {.CartItem = ci, .Discount = discountItems.FirstOrDefault(Function(di) di.SKU = ci.SKU)})
.Select(Function(k)
If k.Discount Is Not Nothing Then

Can someone who is using a 64 bit machine help me pintpoint this crash to either the VS2010 IDE itself or one of the plugins I have installed?
It's the code fragment below. When I copy & paste it into the Main() function of a new VB.Net console app on my Win7 64 bit machine, the VS IDE crashes and dies onthe spot, every time I try it.
Doing exactly the same on a 32 bit XP machine, nothing abnormal happens.
The 64 bit machine does have some IDE plug-ins installed, the biggest of which is DevExpress (the free version), so i think either one of those or the fact that the IDE is running on 64 bit must be the culprit.
This is the code. The static variable can also be made a module-level variable, with the same result.

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles txtMassTrackingNo.TextChanged

As most of you know, .Net framework 4.0/Visual Studio 2010 supports implicit line continuation in VB, which was not available in previous versions (at least not to my knowledge). I have a situation where I am working on an ASP.Net 3.5 application that is targeting a machine that does not currently have .Net 4.0 installed and from what I understand it won't be installed for some time yet on that machine. Obviously, my development machine does have .net 4.0 installed.
With the implicit line continuation feature in VS2010, I sometimes find myself forgetting to add the continuation, and VS2010 does not have an issue with that even when I am targeting a previous version. Additionally, I know that if I actually compile the code (business objects and such), issues with line continuation are not a problem, as the compiled dll works fine as a 3.5 .net file.
My concern is this. There are areas where I am doing VB.Net coding in the code behind(beside?) for the asp.net pages. These would only be compiled on the server when they are first used, but since the server doesn't have the .net 4.0 framework (or even if it did), does anyone know if this would this cause the compilation to fail if I missed a line continuation? If so, is there a way to enforce using line continuation characters in VS2010?
I realize that some best practices might not be getting followed here, but I'm not about to change all the development dynamics around here just yet. Also, I'm not in an environment where I could easily test this out on my own.

Does Anyone know How to read multi-line strings? I am using XmlWriter to write a Multi-Line Textbox to an Xml Document. The Trouble Is I can't figure out how to get the reader to read that multi-line element. I know the writer is writing it in multi-line, but the read just squashes the lines together. Does anyone know how to read that multi-line element properly?

I am having a slight problem whenever I use the multi-line option with labels. No matter what computer I am using, as soon as I accept the text each line seems to move and seems to get worse when I change font types and size.

I have just started using Balloon Notifications in one of my apps for work but need to put the text on multiple line.
Here is my code:
nfi_Pick.BalloonTipIcon = ToolTipIcon.Info
nfi_Pick.BalloonTipTitle = Picked_By & " Added A New Item"
nfi_Pick.BalloonTipText = Desc & " --> Branch: " & Item_Location & " --> Can Be Sent Today!"
nfi_Pick.ShowBalloonTip(3)
But it puts the "Can Be Sent Today" on the same line.

'Check if file exists and warn of overwriting.

If File.Exists("c:EveOreData.csv") Then

I am using VB.net 2010 and SQL client server.I have to make a Weekly Report Manager that stores an Trainees' weekly activity, which would probably be in a paragraph form.I think I can use Textbox (multilined) or Richtextbox for this.But When I tried to store and read the stored data it is not multilined.
Example:
INPUT in textbox/richtextbox: I am a good trainee inserted it in database as textbox.text or richtextbox.text and the result will be:
I ama goodtrainee
So if I retrieve the data it displays a single lined text.How can I do it properly?
