Thread 22 of 25 | Thread Starter | | |  Don Simmonds | Findfirst File extensions oddity?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  |

Thread 17 of 25 | Thread Starter | | |  hyp3n0zy5 | How to fully support all locale settings?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... 2 replies. Last post: |  dulcaoin | {Too Long!} |

Thread 12 of 25 | Thread Starter | | |  hidingmonkey | arraysi want to read 1 2 3 4 or something of that format, four integers with a space inbetween from a text file. Once read i need to store each integer into an array so that it can be used later. How would i do this as i have tried many different ways and none seem to work. So for example , myArray[1]=1 , myArray[2]=2 , etc but it ignores the spaces 1 Reply: |  Rick Carter | Hello, are you using Delphi, or some other programming language? Your code doesn't look anything like Delphi code. And I don't see any "spaces" in your code. |

4 replies. Last post: |  NevilleRichards | A simple way of breaking-out of a long loop would be to have a pause button which sets a boolean pause variable, and include a test for that pause variable in the while loop (given one of the instructions which enables things to work while the loop is in progress). |
