An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. When adding error handling to a procedure, you should consider how the procedure will route execution when an error occurs. The first step in routing execution to an error hand

You can use the On Error GoTo statement to trap errors and direct procedure flow to the location of error-handling statements within a procedure. For example, the following statement directs the flow to the label line: Copy On Error GoTo ErrorHandler Be sure to give each error handler label in a procedure a unique name that will not conflict with any other https://msdn.microsoft.com/en-us/library/office/ff192902.aspx element in the procedure, and make sure you append a colon to the name. Within the procedure, place the Exit Sub or Exit Function statement in front of the error handler label so that the procedure doesn't run the error-checking code if no error occurs. Copy Sub CausesAnError() ' Direct procedure flow. On Error GoTo ErrorHandler ' Raise division by zero error. Err.Raise 11 Exit Sub ErrorHandler: ' Display error information. MsgBox "Error number " & Err.Number & ": " & Err.Description ' Resume with statement following occurrence of error. Resume Next End Sub The Raise method of the Err object generates the specified error. The Number property of the Err object returns the number corresponding to the most recent run-time error; the Description property returns the corresponding message text for a given error. Note In versions 1.x and 2.0 of Access, you might have used the Error statement to generate the error, the Err function to return the error number, and the Error function to return a description of the error. Existing error-handling code that relies on the Error statement and the Error function will continue to work. However, it's better to use the Err object and its properties and methods when writing new code. Versions 1.x and 2.0 of Access returned only one error for all Automation, (formerly called OLE Automation) errors. The COM

error condition is raised. If you have made provision for that possibility, your code can recover gracefully and continue or terminate as appropriate; if not, Access will do its best to handle the error itself -- usually not in the way you would prefer. An untrapped, or unhandled, error is one that is raised by your application and not handled by error-handling code that you write. Such errors are then dealt with by Access's default error-handling routine, which displays the description of the error and, depending on your option settings, may allow you to debug the code. But it also tends to reset the VBA project, so that all global variables are returned to their uninitialized states. And if the database is run using the Access run-time module and not the full version of Access, the application will simply shut down. To avoid having this happen, put error-handling code in (at least) all your top-level VBA procedures. By "top-level" procedures, I mean those that are not called by other procedures you write, but rather are triggered by events. You can also write whatever specialized error-handling you want for lower-level procedures that are called from the top-level procedures, but if a lower-level procedure doesn't have its own error-handling code, its errors will be handled by a higher-level procedure's error-handler, if there is one, so you don't *necessarily* have to write an error-handler for every procedure. By error-handling code, I refer to using the On Error statement to define what will happen and where code execution will continue in the event of an error being raised by your code. Most often you will want to use the "On Error GoTo" form of the statement, to transfer control to an error-handling section in the procedure, from which section, eventually, the Resume statement is used to continue execution after the error has been dealt with. An alternative to this is "in-line" error-handling, which is done by using the "On Error Resume Next" statement. In that case, your own code checks after executing each statement, to see if an error has occurred, and deals with errors right there. Here's a very basic example of error-handling using "On Error GoTo", with comments on the essential elements: code: click in the frame, Select All, then Paste into your code editor Here's an example of in-line erro
