Break Up The Code In A Method Body Into Statement By Statement Symbols/"tokens"?

Apr 22, 2011

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)

Error: Statement Cannot Appear Within A Method Body. End Of Method Assumed

Jul 13, 2011

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 )

Components - "if" Statement Shows An Error " Statement Cannot Appear Outside Of A Method Body"

Jan 29, 2009

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

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"

.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?

Set VS2008 To Break On An Error Inside A Try-catch Statement?

Feb 19, 2009

One of the things I loved about VB6 is that you had the ability to tell the development environment to break on all errors regardless of what error handling you had set up. Is it possible to do the same thing in VS2008 so that the debugger will stop on any error even if it happens inside a try-catch statement?

think that the argument to be passed to the method or sub will be the Case condition but how do I return the corresponding code to enable the GroupBoxes? I have the same issue with resetting all my textboxes to some default text then the user activates more then one event.

If <expression> Then <statement [:statement]> Else [statements] In Concrete Form?

Jan 1, 2010

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this

If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

Exceptions - Can The "Throw" Statement Exist In A Block With No Try/catch Statement

Oct 5, 2009

how to use them then before, but am still a little confused with a few aspects. Here goes:

1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?

2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?

3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?

4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?

5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?

Make A 'like' Statement Or Use Some Kind Of Wildcard To Make The Statement Not Case Sensitive?

Jul 11, 2010

I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?

For Each itm As ListViewItem In ListView2.Items
If itm.Text Like TextBox1.Text & "*" Or itm.SubItems.Item(1).Text Like TextBox1.Text & "*" Then
Else
