我有两个form——form1和form2
我想在form2里面改变form1里面的image的picture属性
form1.Image1.Picture.LoadFromFile(ExtractFilePath('c:/back1.jpg');
可是总是运行通不过,请各位大侠指点一二

为什么还要ExtractFilePath('c:/back1.jpg')呢，这只能返回一个路径，当然运行不过了。

我同意轩辕散光的判断，或者是没有Create，就访问了，就出错了

1、form1未建立就访问，出错
2、form2未引用form1，出错
3、语句form1.Image1.Picture.LoadFromFile(ExtractFilePath('c:/back1.jpg');有问题

没有uses form1
form1 的uses ...,jpeg,...
form1.Image1.Picture.LoadFromFile('c:/back1.jpg');
