But that's interesting, I'd have to try it to really see what you're saying. OTOH, I'd say you have a hit if it were "hello!", eh? -- ..NET: It's About Trust! http://vfred.mvps.org

Okay...I'm going to go code digging to see what I did back then...and if I even broached the "whole word" option. I had *just* started using VB5 back then (I avoided 4 like the plague), which means I was still using VB3 more than anything else. It may not be pretty to look at. -- Customer Hatred Knows No Bounds at MSFT Free usenet access at http://www.eternal-september.org ClassicVB Users Regroup! comp.lang.basic.visual.misc Bawwk!

Nope it doesn't find hello in that string so wordpad in an English locale counts numbers as part of a word. But If I add an _ to the begining and a + at the end and search for the original string it ignores the two new characters. -- ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org |
