.net - Convert C# Statement Body Lambda To VB?
Oct 14, 2009
It appears that VB in VS8 doesn't support/convert lambda expressions with a statement body. I'm using them in my C# application, but now must convert it to VB.I'm creating a whole bunch of controls dynamically, and I want to be able to give them event handlers on the fly. This is so I can build a dynamic user interface from a database. In the following code I'll create a form and a checkbox, make the checkbox control the form's visibility, add a few method handlers to the form, and then add the newly created checkbox to a pre-existing form/panel/etc. Handlers for the form, for instance, affect the checkbox:
[Code]...
I really liked the ability to create everything on the fly, and then let the objects handle themselves - I don't need to add any special functions that figure out which form is giving the close event so it can search for the right checkbox and update the checkbox - It Just Works (TM).
Unfortunately it needs to be converted to VB. What is the best way to convert lambda/anonymous statement bodies into something that will work in VB, especially when one needs to create many of them?

I'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)

This is probably the piece of code with the most errors: i have inserted the errors as comments under which parts they are to do with but some of them shouldn't be there because there are preceding ifs and property methods.

I have the following vb code which works as expected when it's in a code-behind page. I tried to move it to a shared or component page since I will need to use it in multiple pages:
Imports Microsoft.VisualBasic
Public
Class DetTime
'Determine eastern time
[CODE]...
However the "if" statement shows an error " statement cannot appear outside of a method body" and the Microsoft solution is to "move statement into a procedure or subroutine"

In looking at Fuzzy Date Time Picker Control in C# .NET? Piotr Czaapla's answer to that question is exactly what I need. unfortunately, I'm a VB.NET guy and I'm not that familiar with lambda expresions, so my attempts to convert the code have resulted in hours of misplaced parenthesis and banging my head with a brick.
Any chance some bi-lingual wizard could convert the C# code to VB.net for me?

I have this function that maps a IDataReader to a class. It is obviously written in C#. My co-worker wants to use the same method in his code, but he is writing in VB.net. Basically I am having difficulty rewriting this due to the Lambda expressions used in C#. He is running .Net 3.5.

How would you convert this to VB (using .NET 4.0 / VS2010) ?
bw.DoWork += (o, args) =>
{
Code Here
};
I thought maybe like this:
AddHandler bw.DoWork,
Function(o, args)[code]....
But it says Function does not return a value on all code paths.

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )

I have a custom timer that acts like a Wait for some number of milliseconds and then execute a function. It looks like this:
Public Class MyTimer
Inherits Timers.Timer
Public Event Done()
[code]....
(So, every one second, Timer checks if TextBox1 is empty. If it isn't, it displays a message box and stops checking.)I get a warning that Timer is used before it has been assigned a value, but it is used in the statement that assigns its value. The timer's interval is required to be greater than zero.

convert this C# to VB.NET? convert it manually (translators are not doing a proper job for this) or at least let me know step by step what is happening in this statement so I can do the approrpriate translation myself.

I'm just getting my feet wet with LINQ but am struggling to convert this SQL statement to LINQ.
Dim SQLString As String = "SELECT MESSAGE_ID FROM " & Schema & _
".PPM_TRANSFER_EMAIL WHERE TO_CHAR(IMPORTED_DATE,'YYYY/MM/DD') <= '" & _
DeletionDate.ToString("yyyy/MM/dd") & "' AND IMPORTED = 'Y' AND FILE_NAME LIKE '" & _
mb & "%'"
I have a Dataset that already contains all the data from the PPM_TRANSFER_EMAIL table so it seems silly to query the database again when I can use LINQ to query the dataset.

While I understand there are properties of MailItem that would allow one to programmatically create a formatted email, I would prefer the ability to copy the body of an email that is already formatted to my liking (bolding, italicizing, embedded pictures/tables, set margins, etc.) copy and paste it to a newly composed email such that this formatting is preserved.

I am trying to do what I thought would be simple (especialloy since it worked like a charm in VB 6 with the mapi control:The program populates a multi-line text box with information based on user selections The user hits a button and it pulls up his email client with the subject and body filled in so that he can select a recepient and send off the information. The problem. The text always comes out as a single line run together How can I get line breaks back into the body?
The code that doesn't work is:
Dim sendthis As String = ""
sendthis = sendthis & "mailto:"
sendthis = sendthis & "&subject=New Loss for client " & frmMain.Clt & " Number: " & frmMain.Claim (frmMianClt and frMainClaim are string properties of the mdi container)
