Can anybody please explain why Findfirst, when searching for *.htm will also find .html etc. and what please is the workaround. Was this designed for dos only when there were only three letters?, The real problem is that many web sites include duplicate files one for each of the extensions. Passing the output of Findfirst to a Stringlist with duplicates trapped will not of course solve the problem., Hopefully thanks., Don

I have a program that does a lot with strings, and is required to work everywhere in the world, so also in Asia for example. What is the way to do this in Delphi? Only use the Ansi... string functions? If i understand correctly the default string type should support this. If i write code like, , var SomeString: string;, SomeChar: char;, begin, if SomeString[1] = SomeChar then blablaDoes this work in other locales? If not how to do this? How do i get the length of a string (in characters)?, , If i understand correctly the only reason Delphi is not 100% unicode is because it would break Win9x compatibility. Please go ahead Borland! I don't want to worry about this crap...

I am looking for an easy way to read a users input from a badge. Inbedded on the badge is a CNTRL O to confirm that the badge is being used. So a typical response would be 1445 CNTRL O. After I know the badge is used, I just strip the 1445 and apply it to the job database. , My confusion is the vchar and vcharcode. HLEP, , hr41pearl
