    Visual Basic is, as its title proposes, a "visual" dialect and this permits programmers to put simultaneously submissions very quickly. Visual Basic is furthermore an "event-driven" dialect, significance that, for demonstration, a button bang has cipher that executes at the time of the click. There are cipher measures that numerous developers pursue to make cipher readable. There are furthermore modes to optimize cipher that developers might not habitually understand about.
    Database Access
    Avoid holding an open database attachment all through the execution of your program. Visual Basic was conceived to make an attachment to a database, present the interaction and then disconnect. Also, use retained methods for injects, revisions and deletes because they manage not have to be understood by the Visual Basic compiler; thus, they execute much quicker and decline mesh traffic.
    Error Handling
    Handle mistakes with a try/catch loop. Every function in a program could possibly develop an error; thus, mistake management is essential. Visual Basic 6 programmers normally use the "On Error Goto" procedure for management errors. If an mistake happens, the cipher skips to the "Goto" designated locality and executes those commands. The try/catch cipher applied in Visual Basic 7 (.NET) is noticeably much quicker than the "Goto" mistake management method.
    Performance Improvements
    Turn on "Option Explicit" to force the affirmation of variables before they are utilised and "Option Strict" to avert the implicit alterations of facts and numbers types. This force Visual Basic to present kind validation at amasses time and therefore rises presentation at the time of program execution. Another tilt that proceeds hand in hand with this is to use early binding. Early binding will avert facts and numbers kind validation and coercion when the program executes, therefore conceiving a much quicker program.
    .NET Framework
    Study the .NET Framework and get well renowned with all the built-in functions. Visual Basic .NET has a plethora of purposes and categories accessible from the .NET Framework. Don't reinvent the wheel. Make use of this base of cipher that currently lives for you.
