Well, the next two lines of code would both cause an error (and so would hundreds of other lines if this was a life-size example). If the error occurred anywhere outside the object, it will be handled by whatever error handler is defined there. However, there are scenarios that can greatly benefit from using the finally-block (which we will examine further down), making the use of FINALLY a good idea in general.One last remark about Markus is a supporter of communities in North America, Europe, and beyond.Markus focuses on development in .NET (Windows, Web, Windows Phone, and WinRT) as well as Android and iOS.

If you ant to test your error handling simply add a line of total rubbish, like: lcCode = "sdljfsjdgsfkghks" &lcCode This compiles but errors at runtime.

I don't want to buy the drawbacks of the current TRY...CATCH-implementation in VFP by using TRY...CATCH everywhere and kicking out ON ERROR completely without having any advantages. RE: Advice on error handling AlastairP (TechnicalUser) (OP) 11 Apr 11 07:21 Hi Olaf, Mike,Sorry, I was not being specific.I have set "SET TALK OFF" in the load event of all oWord.Documents.Add() oWord.Selection.InsertAfter(lcText1) oWord.Selection.InsertAfter(lcText2) CATCH lReturnValue = .F. Click Here to join Tek-Tips and talk with other members!

Consider this:

PROCEDURE MainProgram TRY LOCAL llInitComplete,llKeepRunning llInitComplete = .F. Consider the following example:DEFINE CLASS WordExport AS Custom FUNCTION Export(lcText1,lcText2) LOCAL oWord as Word.Application oWord = CREATEOBJECT("Word.Application") oWord.Application.Visible = .T. According to my "theory": This TRY/CATCH is too global :-(. Create a clipboard You just clipped your first slide! 

If so, the card is considered valid. I can go back to my code, can click "fix" in the debug-menu or can change a value of a variable and continue ...

A scenario like this may be desired within an error handler:TRY USE Customer LOCATE FOR LastName = "Gates" IF FOUND() StrToFile("Gates found!","customer.log") ENDIF CATCH TRY StrToFile("Error: "+Message(),"Error.log") CATCH * Nothing we If you do the same thing in the CATCH block, then you get the current stack trace, any ideas on how to get the stack trace at the time of the TRY CATCH• Added in VFP 8.0• Structured Error Handling• Format – TRY – CATCH (WHEN) (TO) – THROW – FINALLY – ENDTRY 15. and even though the CATCH was left via THROW ENDTRY added colors for readability - I think Call me dense, but what's the point of the FINALLY if it executes regardless...??

I know there was an error, but I don't know what do do with it, so... All other errors will be automatically elevated to the outer error handler, if there is one. Well, basically, we want it to be handled the same way all other errors are handled within the outer Try-block. If all of those attempts fail, we would re-throw the error.

If no ON ERROR routine exists, Visual FoxPro displays the default Visual FoxPro error message.

The beauty of classes is that you can encapsulate everything a control needs, including error handling, so that you can use the control in a variety of environments.

The exception object can be invoked simply by using it on the CATCH statement:CATCH TO oException This will make an object named "oException" available within the Catch-block.

Note however, that the error may have occurred before Word ever got instantiated. So, special thanks to those two sources. What's NextJust have fun with the error handler and see if it's useful to you and your applications. Hmmm, thats what I assumed anyways. I am using TRY - CATCH for "local error handling" but to use this structure as the global error handler should also be possible.

Of course, to handle these situations correctly, the outer exception handler needs to be aware of this.Mixing Error Handling MethodologiesStructured error handling is great and will replace traditional error handling in Also, implementing the TRY...ENDTRY to wrap everything will break code which uses ON...ERROR to trap local errors!
