The popup mostly not self-closing hence may stop the batch execution. This is also a major roadblock of unattended execution while moving towards CDCTCI to devops. Hence it is considered a very inefficient technique.
However during the debugging process, to understand the error better, I would suggest not to trap the error info. Instead, display it in a user-friendly manner using Error objects various properties like
The upgraded way to move forward and implement CDCI or devops is to log the error message to a file by implementing logger functionality in a cleanup function.
VBScript Custom Error
VBScript also provides an option to generate a custom error. This feature enables us to react to an error in a user-friendly manner. When we do scripting, we consider several opportunities which may fail the script. We call them assumptions. Using code we try to cover as many assumptions as possible. These assumptions become rules or requirements for us. If in a case, we can not convert directly by code, we create a custom error.I n general, all possible cases need to be coded.
The syntax for custom error:
The Err.Raise() method enables us to simulate errors when we test our error handlers.
Err.Raise() method takes five arguments
- Err.Number- The range of custom error number is between 0 to 65535. However, 0 is not used in many cases as sometimes developer treats o as not an error.
- Err.Source- This is an optional parameter indicating the origin of the error.
- Err.Description-This is also an optional parameter indicating additional information about the error. (It is treated as Metadata about the error.)
- Helpfile-If the error corresponds to a VBScript helpfile, this info is displayed. We need to provide the path of the help file.
- If the error corresponds to a VBScript help file, this info is displayed. We need to provide the path of the help file.
In a script if there are two consecutive errors come, the first error is overwritten by the second error.To get the correct error reporting it is good to clear the Err object.
If Err>0 then Err.Number=9999 Err.Description="A description that matches custom error" Mylogger.log(Err.Number & Err.Description) //this is just to log the Error Err.Clear End if
VBScript engine will automatically execute Clear() method when it encounters On Error Resume Next statement or Exit Sub or Exit Function statements .
When we should use Err.Raise() method?
Error information helps the coders to understand the actual issue. If in case Err.Raise() is used, it will automatically display the masked error message not the original error message. This will make the developers job tough. They will not be able to detect the original issue. Hence during development Err.Raise() should not be used but in production, it should be used.
It is important for us to identify the difference between error and problem statement. While using Custom error we need to provide nice, easy to understand the message to the user. Otherwise, the purpose to use custom, the user-defined error goes in vain.
Rules to generate Custom message:
- Do not use rude or harsh words.
- Use nice words to communicate the error in a descriptive way.
- Try providing a solution or a pointer on how to solve the current issue.
- Apologize for the error.
- Try putting code to recover from the error.
The objective of custom error is to communicate the user that the person has done something against the basic assumption of the code.
Capture or Not to Capture an Error
It is also very important point to decide if we need to capture the error or we should not capture in the script. If we are building small utility to automate something and the script will not be part of the larger framework, we often do not capture the error.
But if you are building a script that will be part of the automation framework, we need to capture the Error messages.It only not only help in debugging but also help us to understand the root cause of the error.
How to Correct Error 80004005
Mistake 80004005 is most likely one of the most aggravating items at any time to be flashed on your computer monitor. Most laptop errors are really particular to a variety of software’s or functions. Mistake 80004005, however, appears to be to be a alternatively generic mistake code as it has a tendency to pop up for all types of explanations.
The error could occur thanks to a trouble with VBScript. This is a computer system script similar to Javascipt. Microsoft utilizes VBScript to interface with a variety of web capabilities like conserving passwords. You can try to take care of the difficulty to start with by making positive that you might be on the administrative account and without the need of limitations. If you obtain that you are by now on these types of configurations, then it might be that your firewall is not making it possible for the web site entry.
A further time the error will manifest is when it has complications connecting. You may possibly get an error information that says you will find a login failure, or it may say anything like “SQL Permissions Trouble”. Possibilities are that this is another mistake in permissions. The will cause for this connectivity challenge can selection vastly in the place the authorization challenge is coming into participate in. Spend notice to the verbiage the error display. It will hopefully give you hints on exactly where to start trouble capturing.
You could have enter information improperly, triggering the 80004005 mistake. For instance, if you get this error right after making an attempt to submit facts with figures like a mobile phone number or a social security selection, consider going again and coming into them as strings as a substitute of straight figures. For occasion, alternatively of putting a telephone range like 5551234, but 555-1234.
Error 80004005 may possibly occur up whilst you might be striving to log in to your immediate messenger. The very first thing to do if this transpires is to examine and see if you’ve got obtained the latest edition. Most quick messengers do regular updates with new features and script. Older versions can quickly become obsolete. It is really a good concept to update each time prompted to do so, and just about every so usually (each and every couple of months) go to the immediate messenger’s internet site to see if there is certainly a newer edition you could be applying.
