本文介绍了在使用SpatialFilter查询时遇到的HRESULT:0x8004020A异常问题及其解决办法。错误主要是由于esriSpatialRelEnum类型的误用及QueryFilter条件设置不当导致。


如果其事件类不存在,则无法储存订购 (异常来自 HRESULT:0x8004020A)


报错位置使用了SpatialFilter查询，后发现是由于使用错了esriSpatialRelEnum类型导致。

网上查资料发现，也有部分人是由于QueryFilter中的条件是按照数据库写的，使用在mdb中、shapefile中的数据时会报错。

反爬虫：请求头中 Token 的反爬机制详解，并设计带 Token 校验的网站

Token反爬机制通过动态生成的加密令牌提高爬虫攻击门槛，其核心原理包括：服务端密钥、动态参数（如时间戳）和加密算法（如MD5、SHA-256）的组合。常见Token生成方式包括前端JS动态计算、服务端签发（Session/JWT）和基于用户行为的验证。该设计通过接口不可预测性、时效性控制和环境检测（如浏览器特征）有效阻止直接API调用，需配合逆向分析JS代码才能破解。示例演示了FastAPI实现的Token验证新闻网站，后端生成时效性MD5 Token，前端通过AJAX携带Token获取数据，非法请求将被

通过ICursor对Table进行操作（添加、修改、删除）     连接上数据表的目的就是对其进行包括浏览、添加、修改、删除等基本操作。 浏览功能，之前文章中一提到，就是将Itable转换为DataTable与DataGridView的DataSource绑定实现。此文主要实现添加、修改以及删除功能。 （1）添加： 首先获取ITable，

问题起因： 报错：Unidentified Error 错误的解决方法： 我经常会用arcgis结合天地图做数据分析工作，天地图使用起来比较方便， 平时使用得很顺手。 最近遇到了比较棘手的问题，突然天地图不能够添加到arcgis中了，关键是之前是可以用的，主要还是有时候可以用，有时候又不能用了。很烦！！ 关键是有时能用有时又不能用，你要是一直不能用也就算了，关键是曾经能用，感觉莫名其妙，很烦！！ 而在最近几个月里突然又不能够添加到arcgis中了，于是我一直在寻找解决办法: 1.修改注册表值方法 2.【A

嗯，用户提出了一个关于STM32 HAL库驱动OLED时遇到的两种初始化代码问题：A类型导致雪花屏，B类型完全不亮。这看起来是典型的I2C通信时序或配置问题，需要结合硬件特性和HAL库特性来分析。 用户提供的引用资料很有...

ArcEngine中HRESULT:0x80040228 异常解决办法

从昨晚到现在一直在纠结这个HRESULT:0x80040228异常。因为我写的功能是打开矢量数据。这几行代码，无论写多少遍应该也不会出错。所以在抓狂中。没有静下心来找答案。通过洋仔百度，才发现原来要在子窗体中也要拖入License空间。 解决办法：把Lincense 空间拖入到窗体中。 转载于:https://www.cnblogs.com/myyouthlife/archi...
