The script starts out by defining a constant named ForReading and setting the value to 1 we’ll need this constant when we open our text file for reading. Will our regular expression work? Let’s find out. So how do we go about finding the desired records? For us the easiest way to do that was to use a regular expression after all, we’re looking for a specific pattern (a number followed by three characters followed by GRP) and regular expressions are very adept at sniffing out patterns (as opposed to finding specific words and phrases). As for lines 4 and 5, well, the less said about them the better. Granted, Line 3 has GRP in the designated spot however, line 3 doesn’t begin with a number. The remaining characters are – well, again, it doesn’t matter.īased on these criteria the first two lines in the text file are the only two lines we’re looking for: they both begin with a number and then have GRP in the fifth, sixth, and seventh character spots. These happen to indicate different product groups. The fifth, sixth, and seventh characters are GRP. The second, third, and fourth characters are – well, it doesn’t matter. This character indicates a specific product type. The first character is a number, 1 through 9. WT is looking only for those records (lines in the text file) that meet the following criteria: Set colMatches = objRegEx.Execute(strSearchString)īefore we explain how the script works we should note that, based on WT’s description, we have a text file similar to this: 1XXXGRPABCEFG Set objFile = objFSO.OpenTextFile(“C:\Scripts\Test.txt”, ForReading) Set objFSO = CreateObject(“Scripting.FileSystemObject”) Set objRegEx = CreateObject(“VBScript.RegExp”) How are they supposed to do that? Here’s how: Const ForReading = 1 But that’s another story.) For example, some people need to be able to retrieve a list of specific products from a text file. (We’re also responsible for creating many of those problems in the first place. Alternatively, it could be due to the fact that, just when things start looking up, someone invents a new menace to worry about, and provides a solution to a problem no one even knew existed.īy contrast, the Scripting Guys only provide solutions to problems that do exist. That could be due to the fact that money and material goods truly don’t buy happiness. The Scripting Guy who writes this column finds this all very interesting, in part because there is plenty of research to indicate that even though our lives continue to get better and better people continue to get unhappier and more depressed. To tell you the truth, no one ever hides in any of the Scripting Guys’ cars.īut, then again, that could simply be because no one wants to catch a Scripting Guy. But do we really need heartbeat sensors in cars? We’re just not sure. It makes sense to have smoke alarms in houses houses do occasionally catch on fire. Nevertheless, we’d be curious to know how often this sort of thing happens. And we don’t doubt that this very thing has happened before: someone has opened their car door and been pounced upon. Before we get to today’s question we were wondering if anyone else has seen the commercial for the car that features the all-new “heartbeat sensor?” The idea is that, before you open your car door, you check the sensor, which can detect the heartbeat of anyone who happens to be hiding in the car waiting to pounce on you.Īs a general rule the Scripting Guys are opposed to people hiding in cars waiting to pounce on unsuspecting drivers.
