向各位大佬们求助，急急急，批量转换尺寸时遇到的灾难^-^
这段时间需要批量修改图片尺寸，于是就用本网现成的代码，单个转换时没问题，批量转换时就出现‘无内存……’提示，一通出错提示。查看任务管理器，发现可用内存和空闲内存告急，退出软件后，内存数量恢复正常。
后来多次测试后，还是发现还是以下进程的问题，调用一次，内存就下降的历害，不知道怎么释放其运行后不断占用的内存，
代码如下，请各位指导，谢谢
*原图片尺寸改变现有的图片尺寸
*a=resizeimage("c:\temp\37057.jpg","C:\temp\37057_haOK.jpg",1024,768)
*a=resizeimage("c:\temp\37517.jpg","C:\temp\37057_haOK.jpg",0,0)
*WAIT windows (a)
*!* Declare INTEGER ShellExecute IN shell32;
*!* INTEGER hwnd, STRING lpOperation,;
*!* STRING lpFile, STRING lpParameters,;
*!* STRING lpDirectory, INTEGER nShowCmd
*!* = ShellExecute (0, [open], [c:\temp\37517.jpg],[],[], 3) && 原图
*!* =INKEY(2) && 等待2秒钟再查看新图
*!* = ShellExecute (0, [open], [C:\temp\37517_ha.jpg],[],[], 3) && 新图
***768,1365,"c:\temp\37517.jpg","C:\temp\37517_h.jpg"
