vb 自适应分辨率 改变图片位置以及大小
怎么让这段代码只改变位置 不改变image 大小？？？ 因为改了之后会失真Private Type ctrObj

谢谢 --------------------编程问答-------------------- 图片改变大小后丢失信息失真是正常的 --------------------编程问答--------------------
大胡子周末也在线呀 --------------------编程问答-------------------- 没有认真看代码，不过觉得可以说一下原理：
楼主用的代码估计是重画所有控件的代码，所有控件根据屏幕尺寸重新按比例确定大小，如果编程时与运行时屏幕尺寸比例不一样会造成变形。
有一种方法可以实现不变图形比例，方法是不使用以上的代码，自己编写代码，不过要规定自己的所有控件在屏幕上的相对位置，应该比较好实现。 --------------------编程问答-------------------- 楼主，别烦恼了，使用这个控件RESIZE32.OCX就解决了，只是之前老外写的，若有需要，我可以发给您。 --------------------编程问答-------------------- 借过，学习下。 --------------------编程问答-------------------- http://ishare.iask.sina.com.cn/f/9570436.html
