WideInputQuery function fails while InputQuery does not
I've noticed that there is a problem with WideInputQuery function.
In the code beneath I get an error message: 'type mismatch'.
Replacing WideInputQuery with InputQuery solves the problem.
var
Value: String;
begin
Value := 'Meaningless filename.txt';
if WideInputQuery('Incorrect filename',
'I am not able to produce any meaningful filename!'+
' Would you mind giving it manually?', Value) then FileName := Value;
end.Regular Expressions are not as hard to understand as you may think. Check ReNamer's manual or nice Regular Expressions tutorial for more info and start to use full power of applications that use them (like ReNamer, Mp3Tag and so on).

Re: WideInputQuery function fails while InputQuery does not
function WideInputQuery(const ACaption, APrompt: WideString; var Value: WideString): Boolean;
function InputQuery(const ACaption, APrompt: String; var Value: String): Boolean; You might have missed that WideInputQuery expects all parameters to be of WideString type, while InputQuery expects normal String types.
In your code you simply have to declare your Value as WideString to make it usable in the WideInputQuery function. Variable parameters must always be of the exact type, no type casting there.

Sorry to trouble you Denis.
Missed pretty obvious.
