According to the On Error Statement : Originally Posted by MSDN An "enabled" error handler is one that is turned on by an On Error statement; an "active" error handler is an enabled handler that is in the process of handling an error.

If an error occurs while an error handler is active between the occurrence of the error and a Resume , Exit Sub , Exit Function , or Exit Property statement , the current procedure's error handler can't handle the error. Control returns to the calling procedure.

If the calling procedure has an enabled error handler, it is activated to handle the error. If the calling procedure's error handler is also active, control passes back through previous calling procedures until an enabled, but inactive, error handler is found. If no inactive, enabled error handler is found, the error is fatal at the point at which it actually occurred. Each time the error handler passes control back to a calling procedure, that procedure becomes the current procedure.

Once an error is handled by an error handler in any procedure, execution resumes in the current procedure at the point designated by the Resume statement. Note An error-handling routine is not a Sub procedure or Function procedure. It is a section of code marked by a line label or line number.

Yep there is your answer. OERN turns off error handling, it just the wrong thing to be using in your example. Also it does nothing in an error trap as the error has already been trapped, you have to exit your error handler for it to be able to handle another error. DataMisers code does this - If your sub errors; - enters errorTrap which handles error in your main sub, - then exits your error trap and goes to CleanUp.

You cannot set a handeler from within an active handeler. I hope this is clear now. All the other posters are correct. The handeler must be completed before setting a new handeler. BruceR your post 6 doesn't provide an answer as it's not going to an error trap. So it wasn't what I wanted and so it wasn't clear at that point. Because "it's how it is" Bonnie posted already a Docu-snippet, which describes that Description: Err.

Last edited by jmsrickland; Feb 12th, at PM. Feb 12th, , PM 3. Re: On Error Resume Next Thanks, so is there no way of ignoring errors within an error trap or handling them then?

Feb 12th, , PM 4. Feb 12th, , PM 5. Re: On Error Resume Next I realise that, it's an example to ask why on error resume next does not work in an error trap. Feb 12th, , PM 6. What you want is this: Code:. Feb 12th, , PM 7. If condition Then linenum [Else linenum ]. Did you know the GoTo statement is optional after Then and Else? This is true in single-line If statements. You can omit GoTo and simply add the target line number.

This was originally a documented feature of the VB language. Few people understand it correctly. The latter one is much more clear—unless all developers working on the code remember logic operators from their logic course.

The Int function returns the integer part of a decimal number? It returns the largest integer less than or equal to the number. Int 3. This is a source of errors and confusion. The Fix function will always return the integer part. Fix When negative numbers are expected, Fix is more natural than Int. The Let keyword is superfluous. There is no reason to use it. You can always omit it. VB does allow you to write it, but it should automatically delete it, really.

Line numbers are truly outdated Basic. A long, long time ago, all Basic lines were numbered. This is no longer the case. Instead of line numbers, you can use the much more descriptive line labels. Line numbers are rare now. The only useful use for line numbers is error handling. In an error handler, the Erl function returns the line number where the error occurred as long as the number is or less.

This functionality is not available in any other way. LSet and RSet are designed to left-align and right-align text in a string variable. If x is too short, the string is truncated. If x is longer than y , the rest is padded with spaces on the right, making the string left-aligned. RSet does the same, but the padding will appear on the left instead, making the string right-aligned.

These statements are apparently designed for fixed-length strings. Back in the good old DOS days, fixed-length text fields were common on displays and reports, which used fixed-pitch fonts. As user interfaces have become more flexible, fixed-length strings are not so common any longer. LSet can also be used to copy a variable of a user-defined type onto other user-defined types.

This could be dangerous and should only be used with care. A single Next statement can end multiple nested For loops. Next k, j, i is the equivalent of Next k : Next j : Next i. This syntax makes sense rarely if ever. Octal numbers are expressed in digits Octal numbers can be considered obsolete. Since an octal digit represents 3 bits, they were useful on systems with a word size divisible by 3: 6-bit words, bit words and so on.

Visual Basic runs on computers with 8-bit bytes and bit or bit words. In this environment, hexadecimal and decimal numbers are handier and much more common. Since octal numbers are relatively rare, they can cause problems reading the code. To avoid confusion, express numeric values in either decimal or hexadecimal format, which are more widely understood. The largely undocumented On Error GoTo -1 statement is obscure. The statement clears the error that just occurred in preparation for a new error to occur.

It can be used in an error handler that could trigger a new error. If an error occurs within an error handler, execution of the procedure will stop and flow back to caller or cause a crash. In this example, Error 5 will trigger mainhandler and Error 6 will trigger nestedhandler. Should you leave out the line with On Error GoTo -1 , nestedhandler would not execute.

On number GoSub line1 , line2 , line3 …. On number GoTo line1 , line2 , line3 …. GoSub and On.. GoTo are primitive alternatives to Select Case. Both statements provide a way to execute one of multiple branches based on number. The GoSub and GoTo statements alone are not structured programming. The same can be said about On.. GoTo , which are about as obscure as VB statements can get. The existence of these statements in VB code calls for a rewrite. The Local keyword in an On Error statement has no effect.

Leave Local out to avoid confusing anyone with the difference of local and non-local error handlers, as the only option is a local error handler anyway. Local is a legacy keyword. The documentation appears incorrect because QuickBasic 4. But, if either argument is a number, VB will attempt to sum them up:.

Option Base is a legacy statement that defines the lower bound of arrays. The possible lower bounds are 0 and 1, the default being 0. The statement is unnecessary in Visual Basic. VB has always let programmers declare the lower bound of arrays in Dim statements.

This statement is completely useless in VB6. It does have a use in VBA, though. Rem is an old way to add remarks to a program. Visual Basic has supported the handier apostrophe ' syntax since version 1. There has never been any reason to use Rem. The Reset statement closes all open files and supposedly writes all file buffers to disk.

The documentation of VB 6. Another issue is, why on earth would you want to keep your files open and close them all at once? In an error handler, Resume 0 will restart execution from the statement that failed. Resume 0 is exactly the same as Resume without the zero. The zero is both unnecessary and confusing. Anyone reading the code could easily think execution will redo from line 0 and wonder where line 0 might be. The Static attribute in a procedure header forces all local variables to be Static in that procedure.

This is a way to avoid declaring each variable with the Static varname statement. This programming style possibly dates back to the era when local variables were not declared at all. Static variables are preserved between calls to the procedure. Having all variables Static is another thing. Type declaration characters are from an era before Visual Basic. VB has always allowed you to declare datatype with the As Datatype clause. You can declare! The last option is available in VBA 7.

The While.. Wend loop syntax is very old. Loop , available already before VB was invented, has replaced it a long time ago. Today you should use Do.. For most uses, While.. Wend is exactly the same as Do While.. A special case requiring the use of While.. Wend does exist. This is when you need to nest two or more loops and you want to exit several loops with one command.

In this example, Exit Do will exit both the Do and While loops simultaneously. The Width statement is intended for writing text files. It forces a fixed line length on an output file. The Width statement affects successive Print statements but not Write statements.
