class function TDDFVendors.GetGlobalRef: TCustomDropDownFormEh;
begin
if DDFVendors = nil then
Application.CreateForm(TDDFVendors, DDFVendors);
Result := DDFVendors;
end;
如題。。。感謝。。。
另外，我在CB中創建了兩個表單，在主表單中宣告一個子表單型別的變數，報錯：“Type Name Expected”，不知是何原因？，已包含子表單頭檔案，主表單頭檔案如下：

大家來看看哦。。。uj5u.com熱心網友回復：

return DDFVendors;
}

uj5u.com熱心網友回復：
TFCommodityCategory在哪里定義的在#include "f_commodity_category.h"頭檔案里嗎
uj5u.com熱心網友回復：
public: // User declarations__fastcall TDdfCommodityCategory(TComponent* Owner);
TFCommodityCategory *VFCommodityCategory // 這個 TFCommodityCategory 類在哪個 .h 或 .hpp
