Tools To Convert Option Strict Off Code Into Option Strict On?
Mar 28, 2010I 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.

Use Of Option Strict And Option Infer
Feb 22, 20111. 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.

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?
Jan 25, 2012I 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?
