When do you embed mutex in struct in Go?

由 孤街浪徒 提交于 2019-12-17 18:28:13
问题 NOTE: I found the word 'embed' in the title was bad choice, but I will keep it.

If a mutex ought to protect

But this

问题 We are using WMV videos on an internal site, and we are embedding them into web sites. This works quite well on Internet Explorer, but not on Firefox. I've found ways to make it work in Firefox, but then it stops working in Internet Explorer. We do not want to use Silverlight just yet, especially since we cannot be sure that all clients will be running Windows XP with Windows Media Player installed. Is there some sort of Universal Code that embeds WMP into both Internet Explorer and Firefox,

C++ with Python embedding: crash if Python not installed

由 柔情痞子 提交于 2019-12-17 07:05:56
问题 I'm developing on Windows, and I've searched everywhere without finding anyone talking about this kind of thing. I made a C++ app on my desktop that embedded Python 3.1 using MSVC. I linked python31.lib and included python31.dll in the app's run folder alongside the executable. It works great. My extension and embedding code definitely works and there are no crashes. I sent the run folder to my friend who doesn't have Python installed, and the app crashes for him during the scripting setup
