方法 1. 使用 "InvokeApplication" 命令调用可执行应用程序
Note: In most situations, you should use a SystemUtil.Run statement to run applications or to open files in their default application. The InvokeApplication statement is supported primarily for backward compatibility.
例子:
InvokeApplication "E:\Program Files\Internet Explorer\IEXPLORE.EXE"
方法 2. 使用 "SystemUtil.Run" 命令打开一个文件或应用程序
When specifying a non-executable file, the file opens in the associated application.
Note: A SystemUtil.Run statement is automatically added to your test when you run an application from the Start menu or the Run dialog box while recording a test.
Tip: You can also use this method to perform operations on the specified file, similar to the usage of the Windows ShellExecute command.
例子:
SystemUtil.Run “IEXPLORE.EXE”
注意：SystemUtil.Run 和 InvokeApplication的区别在于是否需要指定完整路径
例：
Open a Text File in the Default Text Application (Notepad)
Sub CloseDescendentProcesses_Example()
'The following example uses the Run method to open a file named type.txt
'in the default text application (Notepad). It then types "happy days",
'saves the file using shortcut keys, and then closes the application.
SystemUtil.Run "C:\type.txt", "", "", ""
Window("Text:=type.txt - Notepad").Type "happy days"
Window("Text:=type.txt - Notepad").Type micAltDwn & "F" & micAltUp
Window("Text:=type.txt - Notepad").Type micLShiftDwn & "S" & micLShiftUp
Window("Text:=type.txt - Notepad").Close
End Sub
方法 3. 使用ExecuteFile 函数执行外部定义的函数
If you decide not to associate a function library (any VBScript file) with a test, but do want to be able to call its functions, subroutines, and so forth from an action in your test or from another function library, you can do so by inserting an ExecuteFile statement in your action.
When you run your test, the ExecuteFile statement executes all global code in the function library making all definitions in the file available from the global scope of the action's script.
注意：用ExecuteFile语句执行的函数文件是不能被QTP调试进去的
（You cannot debug a file that is called using an ExecuteFile statement, or any of the functions contained in the file. In addition, when debugging a test that contains an ExecuteFile statement, the execution marker may not be correctly displayed. ）
To execute an externally-defined function:
1. Create a VBScript file using standard VBScript syntax. For more information, see the Microsoft VBScript Language Reference (Help > QuickTest Professional Help > VBScript Reference > VBScript).
2. Store the file in any folder that you can access from the computer running your test.
3. Add an ExecuteFile statement to an action in your test using the following syntax:
ExecuteFile FileName
where FileName is the absolute or relative path of your VBScript file.
4. Use the functions, subroutines, and so forth, from the specified VBScript file as necessary in your action.
方法 4. 使用 "WshShell.Exec" 方法
- Runs an application in a child command-shell, providing access to the StdIn/StdOut/StdErr streams.
Remarks
The Exec method returns a WshScriptExec object, which provides status and error information about a script run with Exec along with access to the StdIn, StdOut, and StdErr channels. The Exec method allows the execution of command line applications only. The Exec method cannot be used to run remote scripts. Do not confuse the Exec method with the Execute method (of the WshRemote object).
例子：
Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("calc")
Do While oExec.Status = 0
WScript.Sleep 100
Loop
WScript.Echo oExec.Status
