Option Explicit Off, Option Infer On, "Name Xxxx Is Not Declared"?

Mar 4, 2009

Using VS2008, targetting framework 3.5, trying to update some VB4 code. Yes, VB4.I have a bunch of legacy code I'm trying to update, and I had the idea of trying to work through it by executing the old code, working out what was causing each error as I came to it, solving the problem, and then moving on.In order to do this, I have sinned and set Option Strict Off, Option Explicit Off and Option Infer On.Yes, I'm going to hell for this.Problem is, I'm still getthing errors that various things haven't been declared.All of these the items showing errors are in the form: itemName(obj)Is my problem that the compiler thinks that these are method calls for methods which haven't been declared?PS: For anyone wanting to tell me not to use these settings, I already know

When creating a T4 template in VB.NET, how do you specify Option Explicit, Option Strict,and Option Infer settings? There's some sort of <#@ #> tag for doing this, but I can't find it.

Set Option Explicit And Option Strict On A Project / Solution Level?

Feb 22, 2011

Is there a way to define those two options on the project/solution level?

Use Of Option Strict And Option Infer

Feb 22, 2011

1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.

2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]

I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.

.net - Option Infer On Or Off?

Dec 19, 2011

Possible Duplicate: Best Practices: Option Infer What is the best way to mix VB.NET's Option Strict and the new Option Infer directives? I am developing a old solution, that was translated from VB6 to the VB.NET.Actually, the default options in files are

Option Strict On
Option Explicit On

I want to use LINQ, and found that is easier to use also the Option Infer On. Less to write, less (so, easier) to read.However, a (conservative, from my point of view) part of the team keeps the Option Infer Off and insist do not use it at all, without explicitly explain the causes.In your opinion, what are the "dangers" of using Option Infer On, along with other two options (Strict and Explicit, both On)?

VS 2008 - Best Practice For Using Option Infer Feature?

Mar 20, 2009

What do you feel are best practices for the use of Option Infer in your projects? In Visual Studio 2008, Option Infer is a directive that allows the compiler to infer the datatype of a declared variable by looking at what is assigned to it. This is a key feature in VS2008 and is used extensively with LINQ statements and queries. However, turning on Option Infer may create pitfalls for future maintenance programmers.

Option Infer - Detect Whether The Integer Should Be Int64 Or Int32?

Feb 3, 2011

Will that detect whether the integer should be int64 or int32? What about if we run the program twice. Once we use small numbers and latter we'll use big numbers?

Let's look at this for example: vb.net Dim vector1 As List(Of Int64)Dim vector2 As List(Of Int64) vector1.Sort()vector2.Sort(Function(x As Int64, y As Int64) As Int64Return y - x

What about if I do: vb.net vector1.Sort()vector2.Sort(Function(x As Int64, y As Int64) As Int64Return y - x

I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far

Tools To Convert Option Strict Off Code Into Option Strict On?

Mar 28, 2010

I have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

Option Strict On - Is Better?

Jun 28, 2010

what do you thinkg about comment below? original article url is also suggested to read.I didnt get why my code will be faster if i use it on. anyone has good knowledge about it?

Although Visual Basic .NET allows you to perform implicit type conversions and late binding, you should avoid these practices. Implicit type conversions and late binding may lead to severe performance problems, runtime errors, code that is difficult to read and maintain,and sub-standard programming practices.Many VB.NET professional programmers believe that leaving OPTION STRICT OFF by default was perhaps Microsoft's worst decision in the VB.NET implementation. Use OPTION STRICT ON.

'option Strict On' Insists On This But Can't See Why?

I have an old programme that was written with 'option strict off' I have been steadily working through it mainly sorting out casting issues but have come up against some that I dont understand.for instance I have a checkbox called tickbox

dim Tickbox as new checkbox

later in the code

dim blah as boolean = Me.Tickbox.CheckState

but option strict insists i cast it as a boolean

dim blah as boolean = CBool(Me.Tickbox.CheckState)

surely the checkbox.checkstate is Booleean?

.net - Get The Value For 'Option Compare' At Runtime?

Apr 4, 2012

For debugging purposes, is it possible to get the value of Option Compare at runtime?

(I am working on a legacy Windows Forms application that uses InStr with the first parameter as String (three parameter version of Instr), without the third parameter that is then determined by Option Compare. Option Compare Text supposedly makes InStr case-insensitive; the default is Option Compare Binary.)
