請問我要如何做才可使我的 control 中的 FileName 屬性欄旁出現 ..., 而且在點選時可跳出選擇檔案的對話框. Jesse Chan

Set your published field type to TFileName

Great, the only thing I don't understand is that why does the TMediaPlayer component specify the FileName property as String but still can get the same effect? Jesse Chan

Because it has registered a property editor (TMPFilenameProperty) for it.
