You need to turn your parameters into AnsiString
type. By doing so, you can write functions like this:
[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program
OutputDir=userdocs:Inno Setup Examples Output
[Code]
procedure StringToByteArray(const S: AnsiString; out ByteArray: array of Byte);
var
I: Integer;
begin
SetArrayLength(ByteArray, Length(S));
for I := 1 to Length(S) do
ByteArray[I - 1] := Ord(S[I]);
end;
function ByteArrayToString(const ByteArray: array of Byte): AnsiString;
var
I: Integer;
begin
SetLength(Result, GetArrayLength(ByteArray));
for I := 1 to GetArrayLength(ByteArray) do
Result[I] := Chr(ByteArray[I - 1]);
end;
procedure InitializeWizard;
var
S: AnsiString;
ByteArray: array of Byte;
begin
S := '•';
StringToByteArray(S, ByteArray);
MsgBox(IntToStr(ByteArray[0]), mbInformation, MB_OK);
S := '';
S := ByteArrayToString(ByteArray);
MsgBox(S, mbInformation, MB_OK);
end;
