今天帮一个加拿大的朋友解决VB调用QTP的问题，自己写了一个Demo 。

下边是源代码
1.新建工程，引入QuickTest Professional 8.0 object library
2.编写代码如下：
Private strScriptName As String
Private strRunScript As String
Private Sub cmdAddScript_Click()
strScriptName = InputBox("请输入QuickTestPro脚本的路径以及名字", "Select Script")
lstQtpScript.AddItem strScriptName
strScriptName = ""
End Sub
Private Sub cmdRunScript_Click()
If strRunScript = "" Then
MsgBox "please select you want to a running script in listbox"
Else
Dim qtApp As QuickTest.Application ' Declare the Application object variable
Dim qtTest As QuickTest.Test ' Declare a Test object variable
Dim qtResultsOpt As QuickTest.RunResultsOptions ' Declare a Run Results Options object variable
Set qtApp = CreateObject("QuickTest.Application") ' Create the Application object
qtApp.Launch ' Start QuickTest
qtApp.Visible = True ' Make the QuickTest application visible
' Set QuickTest run options
qtApp.Options.Run.CaptureForTestResults = "OnError"
qtApp.Options.Run.RunMode = "Fast"
qtApp.Options.Run.ViewResults = False
qtApp.Open strRunScript, True ' Open the test in read-only mode
' set run settings for the test
Set qtTest = qtApp.Test
qtTest.Settings.Run.IterationMode = "rngIterations" ' Run only iterations 2 to 4
qtTest.Settings.Run.StartIteration = 2
qtTest.Settings.Run.EndIteration = 4
qtTest.Settings.Run. ' Instruct QuickTest to perform next step when error occurs
Set qtResultsOpt = CreateObject("QuickTest.RunResultsOptions") ' Create the Run Results Options object
qtResultsOpt.ResultsLocation = strRunScript + "\Res1" ' Set the results location
qtTest.Run qtResultsOpt ' Run the test
'MsgBox qtTest.LastRunResults.Status ' Check the results of the test run
qtTest.Close ' Close the test
qtApp.Quit 'Close QuickTestPro
Set qtResultsOpt = Nothing ' Release the Run Results Options object
Set qtTest = Nothing ' Release the Test object
Set qtApp = Nothing ' Release the Application object
strRunScript = ""
End If
End Sub
Private Sub Form_Load()
strScriptName = ""
strRunScript = ""
End Sub
Private Sub lstQtpScript_Click()
strRunScript = lstQtpScript.Text
End Sub
由于不是具体讲vb的使用所以里面如何新建工程等都省略掉了，如果大家有兴趣可以自己找相关书籍学习。
以上代码在vb6.0 winxp sp2调试通过。
