Article PS040224130 HOWTO: Using Persits components in VB.NET Problem Description Persits Software products and manuals have example code for ASP (VBScript) and C#.NET, but do not include VB.NET samples. This article describes how to declare and create the objects in .NET with VBScript. Solution These code snippets illustrate how to create Persits objects in VB.NET for any .NET environment: an .aspx page, a code-behind file, or a desktop project. These illustrate how to give your object variables specific (early-bound) types, which gives a performance advantage over declaring them as a generic Object type. Once an object is instantiated, its properties and methods can be called just as they would in C#. AspEmail dim Mail as ASPEMAILLib.IMailSender Mail = new ASPEMAILLib.MailSender() AspJpeg dim Jpeg as ASPJPEGLib.IASPJpeg Jpeg = new ASPJPEGLib.ASPJpeg() AspEncrypt dim CM as ASPENCRYPTLib.ICryptoManager CM = new ASPENCRYPTLib.CryptoManager() Other AspEncrypt objects use similar syntax. Here's how to declare CryptoContext and CryptoBlob variables, for example, and examples of setting them: dim objContext as ASPENCRYPTLib.ICryptoContext objContext = CM.OpenContext( "", 1, Missing.Value ) dim objBlob as ASPENCRYPTLib.ICryptoBlob objBlob = CM.CreateBlob() AspPDF dim Pdf as ASPPDFLib.IPdfManager Pdf = new ASPPDFLib.PdfManager() Other AspPDF objects use similar syntax. Here's one example: dim objDoc as ASPPDFLib.IPdfDocument objDoc = Pdf.CreateDocument(Missing.Value) Comments If you have an Import Namespace declaration for the wrapper library, you can omit the verbose prefix for the object names. Here's an example for AspEmail, and the other objects use the same syntax: <%@ Import Namespace="ASPEmailLib" %> dim Mail as IMailSender Mail = new MailSender() AspUpload has a separate article describing its use under .NET. AspGrid does not include a library to use it under .NET.
