视觉论坛的各种NI资源，除了视觉相关的模块有使用外，大部分的都不会使用，仅提供资源不提供技术支持。资源的下载地址一般会同时提供NI官方和百度网盘的地址。某些工具包NI地址失效或没有NI地址，只能使用百度网盘地址；如果百度网盘地址失效过期，可联系论坛客服更新。NI的服务器在美国，有时候速度很慢或下载容易出错，这样会造成安装时各种错误而无法安装。建议在下载完成后，对下载资源做校验和(NI一般会提供MD5或SHA256等)验证，与官方或视觉论坛提供的校验和对比，一致就可以安装；如不一致，则需要重新下载。视觉论坛早期下载上传的资源，基本上都是正常下载的资源；2019后下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘。校验和工具下载地址：文件Hash计算器FHash，文件校验和验证下载文件正确性验证，MD5值计算、SHA1值计算、SHA256值计算、CRC32值计算http://pcmv.cn/thread-26524-1-1.html
