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? Confused 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...

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).

I don't usually go about horn-tooting for Prestwood, but if you really just need to send mail to an SMTP server from the console app, we have a [b]psSendmail[/b] DLL available that can be used from any app that can use DLL's. We have Paradox and VB developers using it in their apps with great success., , , , Check it out at http://www.prestwood.com/products/pssendmail

The recursive call to [b]GetSubDirList[/b] doesn't trigger the Windows Event Handler until it returns from the last call. So "[b]Application.ProcessMessages[/b]" triggers the event handler to repaint the lines in the list box as they are being written.

Threads + sleep method
Hi,, , I have a thread that needs some components from the Form it was called by. I thought of creating a new method Create that would require in his parameters these components, and then set them so I can use them in my thread (I suspect there is a better way to do it). But, when I change the Create method, the Execute method is never called... any idea why?, , Also, I did some testing, and when I start a thread with a call to the Sleep method, even my main program sleeps... any idea how to fix this?

QReport Query SQL
Now I will readily admit that I aren't the brightest candle in the shop window when it comes to SQL, so I need help (Im looking at you Mr Wehrly!)., , My report splits into four groups, each group containing a list of items for that group and their current value. I list my data using QRDBEdits and it works fine. However, I would like to exclude any items where the figure is "0.00". I figure to do this I need a QRExpr instead of the QRDBEdit but I dont know how to make it work properly with the SQL code. In delphi, I would write something like this., , if Currency((Query2.Debit - Query2.Credit)) <> 0 then , , but how to do it in Sql???, , Answer this for me and Ill get around to sending Mike my picture for the avatars. Im growing my beard as we speak!
