请问在工程创建时的启动画面：
frmFlash := TForm.Create()
用Application创建不行，直接TForm.create(frmFlash)也不行
为什么？ 他们有什么区别？
同样，动态生成控件这样又有什么区别？

frmFlash:TfrmFlash;frmFlash:=Tfrom.create();
^^^^^^
如果你定义的是
var
frmFlash:TfrmFlash;
应该用
frmFlash := TfrmFlash.Create()
var
f_flash:tform_flash;
...
f_flash:=tform_flash.creat(application);
f_flash.show;
f_flash.refresh;
Application.CreateForm(TfrmFlash,frmFlash)
和
frmFlash := TfrmFlash.create()
这两种创建有什么区别
因为我在做闪屏时在工程中只能用第二种方法，而第一种不能，为什么？
