write code for every possible type of error, "File Not Found" errors are fairly easy to handle. If you vba error handling function do not write code towork around the error, you can at least provide a message that makes more sense before ending the program. The "On Error" Statement The most common way to vba error handling exit sub handle error conditions is to use Visual Basic's"On Error" statement.The "On Error" statement interrupts the normal flow of your program when an error occurs and begins executing your error handling code. A typical use is as follows :
On Error Goto FileOpenError When this statement is executed, any errors that occur in subsequentstatements cause Visual Basic to stop normal line-by-line execution andjump toVba Access Error Handling
the statement labeled as "FileOpenError". Labeling Code Lines Line labels in Visual Basic are similar to the line numbers of early BASIC.In Visual Basic, line labels can include text if you want, but each label mustbe unique. They are followed by a colon (:), as in the following example : Private Sub Form_Load () On Error Goto FileOpenError Open "C:\SOMEFILE.TXT" For Unput As #1 Line Input #1, sData Exit Sub FileOpenError: MsgBox "There was a problem opening the file. Stop for coffee!" End End Sub In the preceding sample code, if the "Open" or "Line Input" statements causean error, the statements starting at the label "FileOpenError" are executed,causing the message to be displayed and ending the program. You should note a few points about the sample code. First, note the locationand style of the error handling routine. It is usually placed near the end of thesubroutine, with the label not indented to indicate a special section of code. Second, and more important, note the "Exit Sub" statement after the "Open" statement. It is necessary to prevent the error handler routine from executingeven when the "Open" statement was successful.

Roe Errors are bound to happen, but it’s simple to incorporate error handling in your VB.NET and VBA code. Regardless of your programming skill level, errors can occur whenever someone runs your program. The key is handling those errors correctly and efficiently. In most of my previous articles on AutoCAD programming, error handling has been omitted for brevity and clarity in demonstrating other programming concepts. In this article, we&r

Different routines set different osnap settings then at the end of the routine it sets the osmode variable back to the user settings prior to running the command. When a user hits escape (or doesn't select anything during the routine and hits enter to end it) vba error handling the routine does not get to the end to reset osmode to original user settings. I hear something about error handling in a lisp routinein which if a routine doesn't finish it puts the settings back to how the were prior to running the command. Can someone guide in how to write this in the lisp files. Thank you all.

I even found a site that shows how to handle this exact problem, and I can't get the lisp to work right. (defun *error* (msg) (setvar "osmode" *osnap) (princ msg) (princ) ) That's the code it tells me to write, but the osnap settings do not restore after an ESC cancel.
