However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other cases, there may be no apparent indication that any error occurred because the h

Vbscript Error Message
Sign up VBScript — Using error handling up vote 59 down vote favorite 13 I want to use VBScript to catch errors and log them (ie on error "log something") then resume the next line of the script. For example, On https://msdn.microsoft.com/en-us/library/53f3k80h(v=vs.84).aspx Error Resume Next 'Do Step 1 'Do Step 2 'Do Step 3 When an error occurs on step 1, I want it to log that error (or perform other custom functions with it) then resume at step 2. Is this possible? and how can I implement it? EDIT: Can I do something like this? On Error Resume myErrCatch 'Do step 1 'Do step 2 'Do step 3 myErrCatch: 'log error Resume Next vbscript error-handling share|improve this question edited Oct 1 '08 at 14:13 http://stackoverflow.com/questions/157747/vbscript-using-error-handling asked Oct 1 '08 at 14:04 apandit 2,50611831 1 Dylan's response is about as good as VB gets in the Error handling department. This is why I always used Javascript when I could get away with it. –wcm Oct 1 '08 at 14:23 add a comment| 2 Answers 2 active oldest votes up vote 103 down vote accepted VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the reuslts of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation. On Error Resume Next DoStep1 If Err.Number <> 0 Then WScript.Echo "Error in DoStep1: " & Err.Description Err.Clear End If DoStep2 If Err.Number <> 0 Then WScript.Echo "Error in DoStop2:" & Err.Description Err.Clear End If 'If you no longer want to continue following an error after that block's completed, 'call this. On Error Goto 0 The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above. share|improve this answer edited Oct 1 '08 at 14:36 answered Oct 1 '08 at 14:11 Dylan Beattie 33.4k2096154 9 :( ... Too bad I guess... –apandit Oct 1 '08 at 15:12 2 You could change WScript.Echo within the If statement to call a Function or Sub, which could in turn exit the application, log

Error Handling and DebuggingErrors, bugs, on error and therefore debugging are a part of life for a programmer. As the saying goes, if you haven’t made any mistakes, then you aren’t trying hard enough.Dealing with errors actually involves two very different processes: error handling and debugging. Error handling is a combination of coding and methodology that allows your program to anticipate user and other errors. It allows you to create a robust program. Error handling does vbscript on error not involve weeding out bugs and glitches in your source code, although some of the error handling techniques covered in this chapter can be used to great advantage at the debugging stage. In general, error handling should be part of your overall program plan, so that when you have an error-free script, nothing is going to bring it to a screeching halt. With some sturdy error handling in place, your program should be able to keep running despite all the misuse that your users can—and certainly will—throw at it.The following ASP page illustrates some simple error handling:
toError Handling using vbscript in QTP: Unexpected events during a test run disrupt a test or may give invalid test results. For example, during a test run, an application error may occur. This error does not permit the automated test to navigate to the feature, screen, or module that needs to be tested. These unexpected errors and events are called exceptions.It becomes important to handle these exceptions so that we are able to continue with automated testing even in unattended mode. Handling of exception in a manner so that test execution is uninterrupted is known as error handling. Following are the ways in which error handling can be implemented in QTP. •VB Script Error Handling oUsing Test Settings oUsing On Error Statement oUsing Err Object Properties oUsing Exit Statement •Recovery Scenarios Test Settings : Error Handling Error Handling can be defined in Test Settings through File>Settings>Run as shown below: It defines the possible actions in case anerror is encountered during run session Test Settings for error handling Using On Error Statement •On Error Statement On Error statement, which informs theVBScriptengine of intention to handle errors by self, rather than to allow theVBScriptengine to display a typically uninformative error message and halt the program. This is done by inserting a statement like the following at the start of a procedure: •On Error Resume Next: On Error Resume Nexttells theVBScriptengine that, should an error occur, we want it to continue executing the program starting with the line of code that directly follows the line in which the error occurred. •On ErrorGoto 0: This turns off the error handling Err Object Properties and Methods TheErrobject is part of theVBScriptlanguage and contains information about the last error to occur.Some of the most useful properties and method of Err object are as follows: Err.Number Property:TheNumberproperty returns or sets a numeric value specifying an error. Number is theErrobject's default property.If the value ofErr.Numberis 0, no error has occurred. Err.Description Property:TheDescriptionproperty returns or sets a descriptive string associated with an error. Err.Clear Method:TheClearmethod clears all property settings of theErrobject. Following is a code snippet how error handling can
