When a user first runs a SoftArtisans XFile script, he or she downloads SAXFile.cab, which contains all of XFile's controls. To make sure that users download SAXFile.cab again whenever you upgrade it on the server, update DLL version numbers in the <OBJECT> tag's codebase attribute, as follows below.

To create a client-side instance of a SoftArtisans XFile object, use the <OBJECT>: tag with the appropriate classid. The classid specifies which control to create (the various classids are listed below). For example, to create an instance of XFile's visual upload control, use,

<OBJECT classid="CLSID:230C3D02-DA27-11D2-8612-00A0C93EEA3C" id="AXFFile" codebase="/SAXFileSamples/saxfile.cab">

The <OBJECT>tag above creates an instance of XFile's visual upload control. Classid specifies the control's unique class id, CLSID:230C3D02-DA27-11D2-8612-00A0C93EEA3C. Codebase specifies the location of saxfile.cab, which contains SAAXFile.dll (the visual control's dll). Id assigns a name to the created instance of XFile's visual upload control.

Note: You can supply any name (for example, "MyUploadControl") as an id. Use the id to refer to the object in your script. For example, if you named the object instance "AXFFile," use the following to add a file to the upload: AXFFile.AddFile "x:\filename.ext

The codebase attribute specifies the location of XFile's visual upload control. When you upgrade XFile, add a control's new version number to the codebase attribute. To find the version number for the visual control (for example),

• Extract SAAXFile.dll from SAXFile.cab
• Right-click SAAXFile.dll
• Open Properties
• Select the Version tab

Let's say the version number is 1.0.9.1. Add "version=1,0,9,1" to the codebase attribute:

<OBJECT classid="CLSID:230C3D02-DA27-11D2-8612-00A0C93EEA3C" id="AXFFile" codebase="/SAXFileSamples/saxfile.cab#version=1,0,9,1">

The following table lists the objects you can create using the <OBJECT> tag, the dlls containing the objects, and their classids.
