blueshell Error Guy : you really need it!
If you have any calls to user-defined functions or subs in your code (have you ever seen another program?), you need to be very aware of this feature of Visual Basic's error handlers; it can cause control to unexpectedly jump into your calling procedure's error handler. And if there isn't a calling procedure (as in all event handler subs like Form_Load, OK_Click etc.) your application will abort immediately. For this reason, we can only recommend that you include an error handler in at least every event handler procedure in your application. This may seem like a lot of work, and it definitely increases the size of your code, but the alternative is worse.
Using blueshell Error Guy you can do it quickly and without any problems.
In any programming environment, you have to deal with errors, and Microsoft Visual Basic is no different. These errors fall into three categories:
Compile-time errors - occur when your code contains incorrect syntax.
Run-time errors - occur when a condition raises an error at runtime.
Logic errors - occur when your code doesn't do what you intended because of improper logic or misunderstanding.
Our software tunes your code, providing that it will handle run-time errors safely.
blueshell Error Guy is designed for developers who create Microsoft Visual Basic programs.
With its easy-to-use interface, blueshell Error Guy allows you to organize many types of error handling.
When a run-time error occurs, you have several ways of dealing with it. Resolving errors requires three steps:
Setting an error trap
Reacting to the error
Exiting the error handler
Don't bother about that. Simply use blueshell Error Guy . Our software is useful for all these steps.

If your Java program has been thoroughly tested but still error-prone,
the Wasp analyser can help to detect subtle run-time errors
and weak points in your program.
The following kinds of errors may be statically detected:
null pointer exception, impermissible cast,
array index out of bounds, division by zero, etc.
The following kinds of weak points may be detected:
uninitialised variable,
unreachable branch in conditional or switch statement,
unreachable loop body or catch clause,
assignment of variable whose value is never used,
unreachable main exit of method, etc.
Wasp produces detailed and precise method call graph.
The method call graph of a program helps to know for each method
what actual methods are called in its body.
Additionally, for each method you may know where this method may be called.
In comparison with other static error analysers,
Wasp has two important advantages.
Wasp is able to distinguish between a definite error,
a possible error (warning), and a potentially erroneous situation.
In the latter case, Wasp produces a message called
conditional error that in practice appear to indicate an error
in approximately one case from five.
Wasp performs context-sensitive data flow analysis,
so it is able to recognize an error that appears only for some calls
of the method containing it, but does not for other ones.
All known to us static analysers (e.g. QStudio Java, MetaMata Audit, etc)
that statically detect run-time errors may produce
only long lists of warnings because they
can not recognize definite errors in a program due to weak
analyses applied. A user has to waste much time to analyse all warnings.
Wasp has proven its ability to find subtle bugs in programs even
after debugging and testing stages of development because Wasp
detects situations of real complexity.

Take cover from run-time errors, test, debug and profile your code. VB Watch is 3 tools in one: Profiler, Debugger, and Protector. Increase the quality, stability and performance of your Visual Basic programs. - Measure performance. See which 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. - Add advanced error handlers. 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. - EXE 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? Setup breakpoints to your exe's and see what's really happening. - Ensure 100% test coverage. Are you sure you tested all your code? VB Watch Profiler records your test sessions as you execute your code. It shows you in red which procedures and lines are still untested.

Janino is a compiler that reads a Java expression, block, or source file, and generates Java bytecode that is loaded and executed directly. It is not intended to be a development tool, but an embedded compiler for run-time compilation purposes, such as expression evaluators or "server pages" engines like JSP.
Properties
The major design goal was to keep the compiler small and simple, while partially sacrificing completeness. I don't like the idea of carrying around huge libraries for simple applications. See Parser for the list of implemented and missing language features.
When do you need an efficient expression evaluator?
Say you build an e-commerce system, which computes the shipping cost for the items that the user put into his/her shopping cart. Because you don't know the merchant's shipping cost model at implementation time, you could implement a set of shipping cost models that come to mind (flat charge, by weight, by number of items, ...) and select one of those at run-time.
In practice, you will most certainly find that the shipping cost models you implemented will rarely match what the merchant wants, so you must add custom models, which are merchant-specific. If the merchant's model changes later, you must change your code, re-compile and re-distribute your software.
Because this is so unflexible, the shipping cost expression should be specified at run-time, not at compile-time. This implies that the expression must be scanned, parsed and evaluated at run-time, which is why you need an expression evaluator.
A simple expression evaluator would parse an expression and create a "syntax tree". The expression "a + b * c", for example, would compile into a "Sum" object who's first operand is parameter "a" and who's second operand is a "Product" object who's operands are parameters "b" and "c". Such a syntax tree can evaluated relatively quickly. However, the run-time performance is about a factor of 100 worse than that of native Java code.
