On Error Goto 0 is a statement commonly used in Visual Basic for Applications (VBA) and other programming languages to handle runtime errors. However, encountering the "On Error Goto 0" error can be frustrating, especially if you're not familiar with error handling mechanisms. In this article, we'll explore what On Error Goto 0 means, its purpose, and most importantly, provide you with 5 ways to fix the error.
Understanding On Error Goto 0
On Error Goto 0 is a statement that disables error handling in VBA. When this statement is executed, any runtime errors that occur will cause the program to stop execution and display an error message. The "0" in the statement refers to the line number where the error occurred.
The primary purpose of On Error Goto 0 is to reset the error handling mechanism to its default state, which is to stop execution and display an error message when an error occurs. This statement is often used in conjunction with other error handling statements, such as On Error Resume Next or On Error Goto [label], to manage error handling in a program.
Causes of On Error Goto 0 Error
The On Error Goto 0 error typically occurs when:
- The error handling mechanism is not properly set up.
- A runtime error occurs, and the program is not designed to handle it.
- The On Error Goto 0 statement is used incorrectly or in the wrong context.
5 Ways to Fix On Error Goto 0 Error
Here are five ways to fix the On Error Goto 0 error:
1. Properly Set Up Error Handling
Ensure that you have properly set up error handling in your program. Use the On Error Resume Next statement to allow the program to continue execution after an error occurs. You can also use On Error Goto [label] to direct the program to a specific error handling routine.
On Error Resume Next
2. Use Error Handling Routines
Create error handling routines to manage errors that occur during program execution. Use the Err object to retrieve information about the error, such as the error number and description.
On Error Goto ErrorHandler
' Program code here
Exit Sub
ErrorHandler:
MsgBox "Error " & Err.Number & ": " & Err.Description
Resume Next
3. Check for Errors
Regularly check for errors during program execution using the Err object. This allows you to handle errors before they become critical.
If Err.Number <> 0 Then
MsgBox "Error " & Err.Number & ": " & Err.Description
Err.Clear
End If
4. Use Debugging Tools
Use debugging tools, such as the Visual Basic Editor's debugging tools, to identify and fix errors. These tools allow you to step through your code, set breakpoints, and examine variables to identify the source of the error.
5. Reset Error Handling
Reset error handling to its default state by using the On Error Goto 0 statement. This will ensure that any runtime errors that occur will cause the program to stop execution and display an error message.

Final Thoughts
On Error Goto 0 is an essential statement in VBA programming, but it can also cause frustration when encountered as an error. By understanding the causes of the error and using the 5 ways to fix it, you can ensure that your programs are robust and error-free. Remember to always set up error handling properly, use error handling routines, check for errors, use debugging tools, and reset error handling as needed.
