Answer / Ajit Singh
To read DOS environment variables in Delphi, you can use the GetEnvironmentVariable function. Here's an example:nn```delphinfunction GetDosEnvVar(const VarName: string: string): string;nbeginn result := '';n var Len := Length(PChar(VarName)) + SizeOf(VarName);n if GetEnvironmentVariable(PChar(VarName), @Len, PChar(Result)) thenn SetLength(Result, Len)n end;nend;n``

I'm using Delphi 4/5 and have am trying to fill a RichEdit control with both European characters and Thai characters - while I can change character colours the font stays with what was selected for the control:- reLangB.SelAttributes.Color :=dCol; reLangB.SelAttributes.Name :=FontName[dLang]; reLangB.SelAttributes.Charset :=FontChar[dLang]; reLangB.SelAttributes.Style :=[]; reLangB.Lines.Add(dText); The FontName and FontChar arrays contain the font info, and using a similar method for Captions and EditBoexes works! Anybody any ideas? Thanx in advance!
