all possible contingencies, run-time errors will occur in your applications. You can vba error handling display message and should do all you can to prevent them, but when they happen you have to handle them. on error goto line Introduction Trapping Errors at Run-Time Building Error Handlers Raising Your Own Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in https://msdn.microsoft.com/en-us/library/5hsw66as.aspx Visual Basic expect to deal with certain types of data and behavior in your applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that it can use to derive a date. If you provide input that http://www.vb6.us/tutorials/error-handling it can't convert, it raises error number 13 - "Type mismatch" - essentially saying "I can't handle this input data." In an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can ex

Also, ensure that you vba error handling have specified everything you need to create a new record (i.e.: do any other columns need to be specified or are they allowed to be empty?).

The data type in the order table is number so I'm not sure wgwere I'm going wrong.

of losing unsaved data. If it's not her lucky day, her computer jams and the database corrupts. The system won't start up again. There is no backup. Naturally, she calls you (or your boss) yelling and demanding immediate action. You don't even know the error message. You get sick of such a user and never want to deal with her again. Tired of problems, you quit your developer career and start making burgers instead. Benefit from errors There's nothing positive about errors, is there? How about this way to look at it: When an error hits the user, your application reacts to it in a reasonable way, protecting the data and reporting the error to you. You find the cause of the fault and provide a fix in a short time. The user is amazed by your performance and buys a new project from you. You're the best choice since not only is your software great but you also give the best service. This kind of a paradise is not so far from the reality. With proper error handling you protect the users and get extensive information for fixing the bugs. This article is written with Visual Basic 6.0 in mind. The concepts presented are universal and not tied to a specific language or environment. VB Watch Protector is an automated tool that provides VB applications with the error handling features suggested by this article. What should your app do when an error occurs? When a run-time error occurs, the default way for Visual Basic to handle it is to display an error message and crash. Would you design your apps this way? Instead of the default way, you should trap the error, display a detailed description of what happened and give the user some options to cope with the failure. Retry the operation. If you can't overwrite a file because it's read-only, the user can possibly fix this herself and retry it. Ignore the error and try to continue execution. This is often a practical solution, provided that the code copes with the incompletely executed statement. Always ignore this error. This option is very handy if the same error keeps coming up repeatedly. This could happen if the error occurs in a loop or a recurring event, such as a form's Paint event or a Timer event. Without the option to A
