34 new code review rules

Everyone makes mistakes. The skill is in correcting them before it's too late. Appear smarter than your colleagues: Use Project Analyzer to double-check program logic for thoughtless omissions.

Find dead and undefined code

  • "Dead line label or number" Line label or line number is not used as a jump target.
  • "Dead compiler constant" Compiler constant is defined but not used for conditional compilation.
  • "Undefined compiler constant" Compiler constant is used for conditional compilation but not defined.

Find rotten logic

  • "Unreachable code found" A block of code never executes because it is not reachable.
  • "Empty block" This rule reports empty blocks such as If, Else, Catch.
  • "Variable read before written (along some path)" Potential logic mistake.
  • "Variable read before written" Variable always contains its default value at this point.
  • "Object read before written (along some path)" Run-time error (null pointer reference) could occur.
  • "Object read before written" Run-time error (null pointer reference) is likely.
  • "Assigned value not used" Useless assignment, check logic.
  • "Assigned object not used" Useless assignment, check logic.
  • "Loop runs only once" Potential logic flaw. Why loop just 1 time?
  • "Loop runs forever" No reachable exit from this loop. Potential jam.
  • "Condition always True or False at run-time" Statement is unconditional due to run-time conditions.
  • "Verify accuracy" This floating point constant may be imprecise.

Find rotten parameters

  • "Parameter value not used" Logic flaw: Parameter is overwritten before its value is read.
  • "Passed value not used" Receiving procedure doesn't use this parameter. Could optimize.
  • "Optional parameter never passed a value" Is this parameter superfluous?
  • "Rewrite Sub as Function" Use return value instead of 'out' parameter.

Find rotten design

  • "Possibly orphaned event handler" Sub no longer handles any events.
  • "Event handler called directly" Event handlers should not be explicitly called.
  • "Implementation called directly" Should not call a procedure that implements an interface.
  • "Event handler should be Private" Prevent event handler calls from other modules.
  • "Implementation should be Private" Prevent access to implementation from other modules.
  • "Non-instantiatable class has instance members" Why define members that can't be accessed?
  • "Class/Structure nested inside Interface" Bad programming style.
  • "Magic number found" A numeric literal is not defined as a constant.

Find rotten performance

  • "Slow ^ operator found" Replace ^ by one or more multiplications.
  • "CreateObject found" Use "As New" early binding instead of late binding.

New rules to replace old rules

  • "Microsoft.VisualBasic.Compatibility imported" replaces old rule "Microsoft.VisualBasic imported". The Compatibility namespace is a style problem while the VisualBasic namespace is not.
  • "Conditional block excluded" replaces old rule "Conditional block will not upgrade to VB.NET" and is now available in all editions. Finds lines where #If or #Else block condition is False.
  • 3 rules replace old rule "Return and Exit statement found":
    • Exit Sub|Function|Property found
    • Exit statement found (other Exit statements)
    • Return statement found (VB.NET)

6 new reports and 20 report updates

Find hidden flaws with new dead code rules

Project Analyzer has improved considerably in its ability to detect partially unused code. Dead code detection now finds variables and constants that appear alive, but that are not so in reality.

  • "Variable users all dead." A variable seems to be in use, but the user procedures never execute. The variable is practically useless.
  • "Variable readers all dead." A variable is being read and written. The reader procedures never execute. One or more writes do execute, to no benefit.
  • "Variable writers all dead." A variable is being read and written. The writer procedures never execute. One or more reads do execute, though. Since the variable never gets a proper value, this can be a flaw.
  • "Variable not read, writers all dead." A variable is practically unused and useless. It is never read. Write statements never execute. It looks like a leftover from previous functionality.
  • "Variable not written, readers all dead." A variable is practically unused and useless. It is never assigned a value. Read statements never execute. The variable is a sleeping bug waiting to wake up and cause havoc.
  • Rules similar to the above also exist for UDT fields (Type..End Type).
  • "Constant users all dead." "Enum constant users all dead." A constant is referenced in the code, but the user procedures never execute. The value is effectively dead. If the value should be used, the program contains a flaw. Alternatively, this is a leftover from removed or disabled functionality.
  • "Enum users all dead." An Enum is used as a data type, but the user procedures are all dead. The values in the Enum never appear at run-time. The program contains a flaw or a leftover from previous functionality.

Prevent problems with Enums, Cases and bad conditions

  • "Enum missing zero value" locates incomplete Enums.
  • "Enum with duplicate value" reports duplicated Enum constants.
  • "Enum constant expected" warns if a number appears in place of Enum. Can be dangerous.
  • "Case branch(es) missing for Enum" compares Select Case against Enum and finds unhandled Enum values.
  • "Case useless" finds Case branches that never execute.
  • "Case overlap" finds Case ranges partially covered by a previous Case.
  • "Condition always True" (or False) reports unconditional branches and loops.

Prevent errors before they hit the user

  • "Hard-coded path found" reports directory paths in the source.
  • "ReDim without Dim" tells to add a Dim statement for arrays.
  • "For index variable not local" warns about a potentially dangerous For..Next.
  • "Octal number found" locates hard-to-read numbers (&O10 = 8).
  • "Declare contains ordinal number" reports DLL Declares with the brittle "#1" syntax.
  • "Cyclic recursion found" locates potential stack overflow.

Enforce consistent style

  • "Data-only class found" reports classes missing any operations.
  • "Dataless class found" reports classes having no internal state.
  • "Write-only property found" reports a missing Property Get, or Property Get having a smaller scope than Set or Let.
  • "Trailing comment found" reports end-of-line comments if you prefer full-line comments.
  • "Line too long" triggers when length exceeds your preferred maximum number of characters.
  • "CVDate found, use CDate" finds the old Variant function CVDate.

Watch for risky VB.NET syntax

  • "Type inference used" finds where the potentially dangerous Option Infer On is in use.
  • "Optional parameter in exposed procedure" verifies cross-language interoperability.
  • "File with several classes or modules" demands that each file should consist of a single class or module.
  • "Implicit variable" warns about an invisible variable declaration in a For statement.
  • "RaiseEvent fails via constructor" warns about nasty unfired Events.
  • "Multiple Return statements found" reports procedures with several exit points.
  • "ReadOnly variable expected" shows which variables to mark as ReadOnly.

Enforce VB.NET class design rules

  • "Shared constructor decreases performance" reports the slow Shared Sub New.
  • "Parent class inherited only once" appears for classes having just one child class.
  • "Shared-only class instantiated" locates unnecessary use of As New.
  • "NotInheritable expected" appears for classes with only Shared members, not suitable for inheritance.
  • "Interface ambiguous" appears when an Interface has two methods or properties with the same name.
  • "Interface duplicated" detects superfluous use of an Interface.
  • "MustInherit class missing MustOverride methods" requires abstract classes have abstract methods or properties.
  • "MustInherit class inherits concrete class" requires abstract classes be on top of the class hierarchy.
  • "MustOverride overrides concrete procedure" appears when a class deletes inherited functionality, not providing replacement.
  • "Shared expected" finds methods and properties that could be declared Shared.

Other improvements in v9

  • Report enhancements:
    • Variables and constants report rewritten. Constants display their actual value in addition to their formula.
    • Variable deadness status added to Variable use report.
    • File LOC and age added to File sizes and dates report.
    • Library base address list added to Library report for optimizing your DLLs.
    • Statistics on names added to Dictionary report.

    • Enhanced rules for "Empty procedure", "Unused file", "Dead parameter", "Excess Scope", "Microsoft.VisualBasic imported".
    • Option to Ignore dead Property Get/Set/Let if another accessor is alive. Allow read/write properties also when either read or write is currently out of use.
    • Option to independently switch on/off the following code review rules: "Dead parameter", "ByVal parameter not read".
  • Find window: Search for "Code or String". Search results reformatted for readability.
  • Print code: New option "Bracket structures" emphasizes decision and loop structures.
  • Auto-fix preserves line continuation characters (_) when possible. Auto-fix can split long lines, move end-of-line comments to full-line comments and add a Dim statement before a ReDim if required.
  • Image version and compile time displayed for library files and executables.
  • Unicode support. Load international source in any codepage (character set).
  • Analysis improvements: Single-line Type and Enum blocks. Single-line classic VB declarations such as Dim x:Dim y or Sub x:End Sub. Generic Structure and Interface (Of T). Time literals #11:25:00#.
  • Late-bound and overloaded call resolution is improved a lot, leading to better accuracy with projects using these techniques.
  • Performance improvements for large analyses.
