listview和imagelist的用法。非常着急。

[lj77916]

用一下程序，取的输入法的ico图标，并把图标显示在listview中。给窗体上加载了一个imagelist和listview控件。结果是取某一个文件ico时能够正常显示，如果循环取第二个时，就提示imagelist被另一个控件绑定时不能修改的错误。请大家帮忙给看看，应该如何修改。

问题出现在Call ImageList1.ListImages.Add(a + 1, , IconToPicture(lIcon))这句上，请大家帮忙

没时间帮你调代码了。说下想法吧。
--------------------------------
取某一个文件ico时能够正常显示，如果循环取第二个时，就提示imagelist被另一个控件绑定时不能修改的错误。
-------------------------------
如错误提示所说，“imagelist被另一个控件绑定时不能修改”
而你下面的代码，

For i = 0 To 3
getstrico (imename(i))
Next

每调用一次getstrico (imename(i))就要修改一次imagelist
因此，你要在把imagelist和listview绑定前，一次性给imagelist赋完值。

代码就不帮你写了。

最近我也是遇到相同的问题，好像绑定以后就不能再修改了，很麻烦，现在也没别的方法
