Any number of run-time errors can occur, and if your program does not trap them, on error goto line the VB default action is to report the error and then terminate the program (often
On Error Exit Sub
resulting in the end user calling you and complaining, "Your program kicked me out!"). By placing error-handling code in your program, you can
On Error Goto 0
trap a run-time error, report it, and let the user continue. Sometimes the user will be able to correct the error and sometimes not, but simply allowing the program to crash is not acceptable. You should generally https://msdn.microsoft.com/en-us/library/5hsw66as.aspx place error-handling code in any Sub or Function that accesses files or databases. Your code will typically interrogate the Number and Description properties of the built-in VB Err object in an error-handling routine set up with the On Error statement. In this section, we will look at the following statements: On Error GoTo label On Error Resume Next Following is a brief tutorial in error-handling. To perform this tutorial, you should have a http://www.vb6.us/tutorials/error-handling-visual-basic floppy disk handy. Also, in the VB IDE, make sure that the Break on Unhandled Errors option is set under Tools à Options à General. STEPS: 1. Start a new project. 2. Place four command buttons on the form. Name them and set their Captions as follows: Name Caption cmdCrash Crash cmdGoToLabel GoTo Label cmdGoTo0 GoTo 0 cmdResumeNext Resume Next Your form should look something like this: 3. Code the cmdCrash_Click event as follows: Private Sub cmdCrash_Click() Open "A:\JUNK.TXT" For Input As #1 MsgBox "File was opened successfully" Close #1 End Sub 4. Place your floppy disk in the A: drive. Run the program and click the Crash button. Assuming that you do not have a file called "JUNK.TXT" on your A: disk, the program will "bomb" with the code/message "53 – File Not Found". If you don't have a disk in drive A:, the code/message will be "71 – Disk Not Ready". 5. Code the cmdGoToLabel_Click event: Copy and paste the code from the Crash sub, and add statements so that the cmdGoToLabel_Click Sub looks like the following (the new statements are shown in bold): Private Sub cmdGoToLabel_Click() On Error GoTo OpenFileError Open "A:\JUNK.TXT" For Input As #1 MsgBox "File was opened successfully" Close #1 Exit Sub OpenFileError: MsgBox "The following error occured: " & vbNewLine _ & "

Second add a custom error handler on every function (yes, every function). The error handler we use looks something like this: On Error GoTo {PROCEDURE_NAME}_Error {PROCEDURE_BODY} On Error GoTo 0 Exit {PROCEDURE_TYPE} {PROCEDURE_NAME}_Error: LogError "Error " & Err.Number & " (" & Err.Description & ") in line " & Erl & _ ", in procedure {PROCEDURE_NAME} of {MODULE_TYPE} {MODULE_NAME}" Then create a LogError function that logs the error to disc. Next, before you release code add Line Numbers to every function (this is also built into
