描述不够清楚,也没有图。你的界面是什么界面,是窗体还是其他的什么。
如果是窗体,他会让你导入图片,作为资源存在工程里面。
如果不是,你先要把背景图片放到资源里再调用。
又或者你的界面图片被别的控件挡住了,你需要将别的控件的backcolor属性改为transparent。
总之你想问什么问题,你得描述清楚。

Delphi代码如下:
procedure TForm1.Button1Click(Sender: TObject);
var
购物总价:Integer;
折扣:Extended;
begin
购物总价:=StrToInt(Edit1.Text);
if 购物总价250 then
begin
折扣:=0;
end
else if 购物总价500 then
begin
折扣:=0.05;
end
else if 购物总价1000 then
begin
折扣:=0.075;
end
else if 购物总价2000 then
begin
折扣:=0.1;
end
{
此段的折扣是多少?
else if 购物总价3000 then
begin
折扣:=0.05;
end
}
else if 购物总价=3000 then
begin
折扣:=0.15;
end;
ShowMessage('您享受的折扣是:'+FloatToStr(折扣)
+' 原价:'+IntToStr(购物总价)
+' 折后总价:'+FloatToStr(购物总价*(1-折扣)));
