[C Error] main.cpp(55): E2247 'TDBComboBox::Field' is not accessible
會出現以上錯誤訊息 請問有人知道為什麼嗎?

編輯記錄

動態設定欄位是DBComboBox1->DataField ="name";

.......

我也有這樣設定過 可是他會出現can't find field "name"

ADODataSet->CommandText = "select id,title from questions order by id";
------------------------------------------------------------------------------------
name 欄位你是什麼時候加進去的呢???

其實男生不是真的喜歡你不減肥，而是喜歡你愛吃還不肥；也不是真的喜歡你不化妝，而是喜歡你素顏也好看；也不是真的喜歡你瘦，而是喜歡你瘦卻有胸；也不是真喜歡你獨立，而是他忙的時候別煩他。女孩子，太認真你就輸了。
