问题描述
我目前在MemoBox中输入了一组单词。 问题是如何检查TMemoBox Lines属性的每一行上的特定字母。如果在指定的单词上字母不相似，则应该是错误的，不应计入，如果答案正确，如何使单词出现在单词标签上？
还如何将guess-label属性限制为仅输入5个字母？ 目前正在制作游戏：）
我目前有以下代码：
{***************** CheckALetter ***************}
procedure TForm1.CheckLetter(ch:char);
var
i:integer;
s:string;
goodguess:boolean;
begin
goodguess:=false;
if not (ch in GuessedLetters)
then
begin
GuessedLetters:=GuessedLetters+[ch];
guessesLabel.caption:=guesseslabel.caption+ch+',';
s:=Wordlabel.caption;
for i:=1 to length(TheWord) do {see if the letter is in the word}
begin
if ch=Theword[i] then
begin
s[2*i-1]:=ch; {fill in the letter in display}
goodguess:=true;
end;
end;
wordlabel.caption:=s;
{if not goodguess then drawAPiece(clred);}
If pos('_',WordLabel.caption)=0 then {all underscores replaced by letters}
showmessage('A reprieve!')
else {If piececount=Hangmanlist.count}
begin
showmessage('Oh,oh Goodbye!'+#13 +'(The word was '+theword+')');
{deadlbl.visible:=true;}
end;
end
else messagebeep(mb_IconExclamation);
end;
//On key presss
procedure TForm1.guess_typeKeyPress(Sender: TObject; var Key: Char);
begin
key:=upcase(key);
guess_type.text:='';
If not (key in ['A'..'Z']) then
begin
key:=#00;
messagebeep(mb_iconexclamation);
end
else CheckLetter(key);
end;
end.
解决方法
不确定TMemo的位置。TMemo.Lines只是一个普通的TStringList，您可以创建一个
for i:=1 to MyMemo.Lines.Count do
s := MyMemo.Lines[i-1];
// Do somenthing with s..
