some_variable = GetStringSetting(HKEY_CURRENT_USER, "myApp", "mySection", myKey, defaultValue)
部分的な結果が返されることがあるため、問題が発生することがあります。たとえば、値がWindows 7で表示されている場合、レジストリエディタの値データは「True」と表示され、GetStringSetting関数は最近開始され、断続的に開始され、「Tru」のみが返されます。レジストリから文字列を読み取ると部分データが返される
これは、単純にレジストリの値]ダイアログボックスを開閉することで解決できます。
私はこの質問には時代遅れの技術を使用して、あまりにもあいまいな可能性が推測するが、この問題は私のフリーウェア製品に影響を与えるので、誰でも同様の問題があったかどうかを尋ねる助けることができませんでした。
