安卓开发笔记——自定义HorizontalScrollView控件（实现QQ5.0侧滑效果）
笙之殇: 作者，你好，你发的这个代码复制的时候左边的行数都给复制上了
从‘void*’到‘int’的转换损失精度
菜小波: 64位系统下，指针必须是8字节，你可以想想指针是什么？是用来表示系统内存空间的。64位系统啥意思呢？是指最大可寻址2的64次方的空间。所以指针必须8字节才能完全表示这些空间。尽管当前硬件各方面原因，目前常见电脑存储空间才达到T，也就是2的40次方。
Crashed when delete OGRSpatialReference objects!
qd1308504206: Do you know if you are using the same heap for your application code, and OGR in this case? For instance, are both compiled with /MD to us MSVCRT.DLL (or modern equivelent)? If not, then I suspect the problem relates to cross-heap issues. The solution would either be to use the C API instead of the C++ API or to use alternate methods to create and destroy at least. eg. OGRSpatialReference *ogrsrs = (OGRSpatialReference *) OSRNewSpatialReference( NULL ); ... OGRDestroySpatialReference( ogrsrs ); I realize it doesn't help anything, but at this point I would also like to say that it is a *great* frustration to me that Microsoft continues to propagate this whole "heap per DLL" paradyme which makes it very hard to port C++ libraries from platforms compliant with the C++ language standard. I try to be platform agnostic, but windows consistently makes my life a misery! /me breathes deeply, and steps off the soapbox.
