Project Analyzer

該軟體用於優化您的 Visual Basic和 VBA代碼，幫助您理解和整理已有的工程檔。代碼採用超連結文本和樹型顯示。您可以清理無用代碼、編寫更精練更快的程式檔。Project Analyzer是一款純粹的代碼分析工具，適用于Visual Basic開發人員。

Project Analyzer is a Visual Basic code review and quality control tool. In other words, static code analysis for VB. Detect logic flaws by automated code review. Perform impact analysis before writing changes. Understand poorly documented legacy code. Reverse engineer existing VB projects into diagrams and documentation. Save costs and keep end-users happy by delivering high-quality VB applications with few errors.

• Understand. Project Analyzer helps you understand the undocumented spaghetti code your colleagues wrote. Surf through a large project as hypertext and interactive call trees. View diagrams. Make sense of hopelessly complex monster projects and refactor them into modern systems.
• Improve. Locate bad code, rotten logic, errors and omissions with automated code review. Detect and remove unused dead code. Save your precious time and have Project Analyzer autofix your code.
• Maintain. To help maintenance, Project Analyzer lets you enforce coding standards and generate project documentation.
• Cut costs and improve quality at the same time. Project Analyzer helps you cut costs by automating your efforts. By locating mistakes that are hard to catch by even seasoned developers, Project Analyzer helps you deliver less errors to users and improve customer satisfaction.

其分成以下三個版本

VB Watch

VB Watch包含三種工具：Profiler, Protector 及Debugger。Profiler可衡量性能及測試覆蓋率；Protector實現健壯的錯誤處理；Debugger有助於監控你的可執行檔。其說明如下：

• VB Watch Profiler：VB Watch Profiler lets you measure execution speed. See what procedures are the slowest ones, and which lines or loops are taking up most of the time. Or measure execution times before and after your enhancements.
• VB Watch Protector：VB Watch adds advanced error handlers to your code with a few clicks, keeping your existing handlers fully enabled. Error messages can include: error description, procedure name, line number, parameter and variable values, object properties, call stack, screenshot, run-time library versions, and even execution trace procedure-by-procedure, line-by-line.
• VB Watch Debugger：Trace the procedure calls and executed code lines in your compiled apps. Even better, monitor and pause your app. See its status. What line is it on? What procedures were called with what arguments? Call stack? Which objects are alive? What global variable values are in effect? Setup breakpoints to your exe, dll or ocx and see what's really happening in it. Debugger allows remote debugging at client site via TCP/IP.
• VB Watch Console：The Console works together with Profiler, Protector and Debugger. Run the Console to instrument one or more projects in a batch. You can also call the console from a batch file to add error handling in a fully automated way each time right before you release your program.

分為兩個版本販售：

• Standard Edition= Profiler + Protector
• Pro Edition= Profiler + Protector + Debugger + Console + Profiler reports + Profiler data export

VB Friend

VB Friend - Code at overspeed!

VB Friend is available on an unsupported basis. No features will be added, no bugs will be fixed. There are no known bugs. Compatibility with current operating systems is limited, see below for details.

• Straighten the spaghetti code. Add readability to your code by consistent indentation. VB Friends takes your rules to indent your code with your very own style.
• Add missing variables. Tired of defining variables? Add "Option Explicit" and let VB Friend do the rest. Every time VB finds a new, undefined variable, VB Friend pops up asking for proper declaration.
• Auto-correct. Upgrade your Visual Basic editor with speedy macros. Type "scc" and get a full "Select Case..Case..Case Else..End Select". Type "ite" and get a full "If..Then..Else..End If" ready to fill in! Fully customizable for all single and multiline code snippets.
• Type less. Let VB Friend complete any missing End If, End Select or Next MyVar statements.
• Get more screen space. VB Friend hides VB toolbars automatically when you don't need them. To show them, just move your mouse to where the toolbar was.
• Get rid of "syntax error". Each time VB finds a syntax error it will show you an annoying message box. If you don't need those trivial messages, let VB Friend hit OK for you.
• Quick backup. Backup your project to a .zip file. Make sure you always have working source code and enough interim copies while you work.
• And more features. Quickly navigate backward and forward in your code and forms. Close all code and form windows instantly. Use Bracket Helper to determine which ")" is missing. Drag code to/from Temporary window to move it from place to place. Auto-clear the Debug window. Add 10 extra clipboards that persist between coding sessions, and you get an idea of what to expect.

RegExpr

RegExpr adds regular expressions to Visual Basic 5.0, 6.0 and VBA.

What's in it? RegExpr for VB & VBA is a source code module with support for a full range of regular expressions. Implemented as pure VB or VBA source code, it does not require any additional run-time libraries.

When do I need it? RegExpr lets you use regular expressions in Visual Basic 5.0, 6.0 and Office VBA as if they were built in the language itself.

Can I just use VB's built-in Like and Replace? Sure you can – if you're happy with the features they support. Regular expressions are much more. They can search for all character combinations, allow "Or" rules, verify the number of character occurrences, and support zero-width concepts such as word boundaries, end-of-line and "not followed by".

What's so great about RegExpr? RegExpr for VB & VBA implements a full range of regular expressions in pure source code. It doesn't require any external libraries or run-times. No DLLs to distribute.
