As an addition in those situations you want/have to use On Error Resume next, you can avoid a lot op problems by using the On Error Goto 0 statement. Suppose you have a user control and when you dis-enable it, you want all controls on that usercontrol to go to their dis-enabled state as well to gray them out: Code: Public Property let, enabled(.

What will the users of your program think if it gives them the wrong results?.or does something nasty by mistake? They wont be happy, and they certainly wont think that you are a great programmer! As you are reading this article, you probably think that errors are a bad thing, and so hiding them is a good idea. As you get more experience you find that this is not the case, and errors are actually a good thing - they tell you either that you have done something wrong (and why it is wrong or that something your program relies on isn't working. In either case, vb wants to tell you what the problem.
But rather than let it tell you (by using proper error handling, or none at all or deal with the error appropriately (perhaps by exiting the routine you have decided to put your fingers in your ears and shout '. so when/how should i use it? There are two kinds of situations where it is appropriate: you really dont care if the code runs properly or not, as it can't do any damage. You are expecting errors in certain part of a routine, but due to the size/structure of the routine (or what that particular piece of code does) it's better to deal with the error where it happened text (by checking mber immediately afterwards rather than. If you use the first kind regularly (more than about 10 of your error handling i'm worried! Using the second kind is fine, and is the proper use. Just make sure that you revert to normal error handling after that piece of code (or have error checks all thru the routine otherwise you are back to the problems mentioned above.

Results 1 to 3. Jan 20th, 2007, 04:48 pm #1, classic vb - what is wrong with using "On Error Resume next"? If it is used properly, "On Error Resume next" is a valid method of dealing with errors - but it is a method that needs to be used appropriately for the situation.
While using it means that you don't get any 'annoying' error messages that stop your program, it can easily cause much bigger problems than that, such as: If one error happens, then the code after that point is likely to have errors too (especially. The follow-up error(s) that occur may be simple and 'safe such as getting the wrong result displayed on screen (but not knowing it is wrong). Or they could be much more serious, such as accidentally deleting an important file, because you had an error getting the name of the file that you wanted to delete. If you have made any coding mistakes (such as putting a text value into an Integer variable) then your code wont do what it is supposed to do, and you wont know why. Not only is the problem hidden from you, but so is the location. If you are running within vb, you would normally get the line highlighted - but with "On Error Resume next" you wont. In fact, you wont even know that there was an error, all you will know is that you have made some kind of mistake somewhere in that routine. If you dont know what the problem is, or where it is, how will you fix it?

Troubleshooting: Try this reference, warning - disconnect the network drive that you created in Example1. Note: slogan This Example is designed to half work and generate error message - 800704B3. The difference here is the order of Network2 and Network1. I have also changed the order of RemotePath2 and RemotePath1 to emphasise the difference. Double check that you have altered alanhome to a real server and share, leave offlinehome to generate the error. ' purpose of script to map a network drive to Y: ' substitute alanhome ' deliberate error leave offlinehome to generate an error Set WshShell ell set Network1 twork set Network2 twork driveletter1 "w driveletter2 "y remotePath2 "alanhome" RemotePath1 "offlinehome" pNetworkDrive driveletter2, remotePath2 pNetworkDrive driveletter1. Warning - disconnect the network drive that you created in Example1. Note this Example is designed to map the second network drive and give no error message because of line 6: on error resume next ' vbscript. ' purpose of script to map a network drive to Y: ' substitute alanhome ' deliberate error leave offlinehome to generate an error ' note the next line.
ipat cracks this problem of allocating ip addresses in networks in two ways: For Mr Organized there is writers a nifty subnet calculator, you enter the network address and the subnet mask, then ipat works out the usable addresses and their ranges. For Mr lazy ipat discovers and then displays the ip addresses of existing computers. Download the Free ip address Tracker. Note: This Example is designed to fail! The result should be no drives get mapped and you get an error message. ' purpose of script to map a network drive to Y: ' substitute alanhome ' deliberate error leave offlinehome to generate an error. Set WshShell ell set Network1 twork set Network2 twork.

this point I would like you to experiment with the classic map network drive script. Firstly let us get in synch, please check these three learning goals: to troubleshoot vbscript, to understand what happens when you get an error message. To decide whether to use: 'on error resume next'. Secondly preparing and editing my scripts is particularly important this week. When you examine the three example scripts: a) Substitute one of your real servers and shares for alanhome b) leave offlinehome as it is - this is the deliberate error. Guy recommends: The Free ip address Tracker (ipat). Calculating ip address ranges is a black art, which many network managers solve by creating custom Excel spreadsheets. .
Contents of guy's Scripting ezine 7 - on error resume next. I will let you into a secret, sometimes you need to know a little theory. So before we get on with this week scripts, here is some background information. Vbscript is an interpreted language; whereas other languages like perl and c are compiled first then executed. I hear you saying, 'so what. Who cares?' Well, how the scripting language behaves matters when you are troubleshooting. When I first I saw a vbscript error message, i was surprised, not because there was a mistake, for but because part of the script had actually worked.
