The following code illustrates how these objects can be created: WSHshell = CreateObject("Wscript.Shell") There are two primary objects contained within the Windows Scripting Host. Figure 1 illustrates how the code will appear in the script debugger.įigure 1 - The Microsoft Script Debugger uses the same IDE as Visual InterDev and Visual J++ 6.0 The scripting host objects If no error trapping exists, you will be prompted with a dialog asking if you wish to debug the application.

The following code demonstrates how to deal with errors on an in-line basis: On Error Resume Next Instead, errors need to be handled on an in-line basis. As far as error handling is concerned, VBScript does not have a global error handler. No programming environment is complete with a full-featured debugging environment and the Windows Scripting Host is no exception. A quick word about debugging and handling errors Furthermore, you can execute these script files directly from your applications using the ShellExecute() API simply by specifying the filename. This technique will be illustrated when the Shell Object is discussed in more detail. Yet another alternative is to use the Run Method of the Windows Scripting Shell Object. Alternatively, you can double-click the item in Explorer as well. In Explorer, you can click the right mouse key over the file, and select Open. Running these script files is a very simple task. Set objXL = WScript.CreateObject("Excel.Application") The following is a more complex example that uses scripting to open and control Microsoft Excel: 'This VBScript File opens Excel and creates a workbook Var WSHShell = WScript.CreateObject("WScript.Shell") Set WSHShell = WScript.CreateObject("WScript.Shell") The following files are simple hello world examples the point out the differences between VBScript and JScript: VBSscript: If the script file ends in JS, JScript is used.
