[Linker Error] Unresolved external '_这种错误是怎么回事
[Linker Error] Unresolved external '_SingleBedForm_f' referenced from D:\MB\MB800T-1.5.5T4\FETUSMB800T.OBJ
是面是提示信息，下面说说是怎么错的。
本来主窗体的名子是SingleBedForm，后面我要窗体名子改成了SingleBedForm_f就报上面这个错了。但是_SingleBedForm_f(带下划线）这个函数我没有找不到，也就是没有这个函数。报错的FETUSMB800T.OBJ是主程序工程名称下面是内容
