This allows you to review the details after the error has been cleared. The table might be named "tLogError" and consist of: Field Name Data Type Description ErrorLogID AutoNumber Primary Key. ErrNumber Number Long Integer. The Access-generated error number. ErrDescription Text Size=255. The Access-generated error message. ErrDate Date/Time System Date and Time of error.

The file is properly imported, the issue comes if the user selects a text file of different format, the code will import the improper data into the database and creates a new ErrorLog table. How do I restrict improper data from table? How to do error handling? If a user selects a file that is of improper format (rather than improper data, which generatings an ErrorLog), it will pop up a MsgBox, telling the user vba error handling that the file if not in proper format.

One of best practices to do so in VBA is: Sub example() On Error GoTo err_hndl (.....do something....) E
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 error-handling: code: click in the frame, Select All, then Paste into your code editor Note that you can use a combination of error-handler
