AnsiString |

Matthew Jones | I have a server that uses names and organisations, and must have an 8-bit ANSI
string. It is used for install codes, and I can't have the code require that the user put in #1345; or similar in their name! Given that EWB applications are of course proper Unicode, and I talk to my RO server using UTF8Strings, what options do I have to ensure proper operation? I'd like the browser to be able to do this if possible, but could send it back to the Delphi (XE2) server if needed. I just need to be sure that when someone puts in their name in chinese, or uses a smiley, that they can be show how it will look in basic ANSI in the browser too. It's not about making sure that it survives a transition to ANSI, but that any issues in conversion are seen immediately, if you see what I mean. /Matthew Jones/ |

<< Given that EWB applications are of course proper Unicode, and I talk to my RO server using UTF8Strings, what options do I have to ensure proper operation? >> Just loop through the string and make sure that all of the characters are <= #255: function IsAnsiString(const Value: String): Boolean; var I: Integer; begin Result:=True; for I:=1 to Length(Value) do begin if (Value[I] > #255) then begin Result:=False; Break; end; end; end; procedure TForm1.Button3Click(Sender: TObject); begin if (not IsAnsiString(Edit1.Text)) then ShowMessage('Invalid characters entered'); end; << I'd like the browser to be able to do this if possible, but could send it back to the Delphi (XE2) server if needed. >> Due to how browser applications work, you'll probably want to do both. The part on the front is just for the end-user, the part on the back is for you. Tim Young Elevate Software www.elevatesoft.com |
