...内存拿来转换。
比较建议的做法,浮点数使用字符串来通信传输(比如传输文本"3.14"),不要用float的原始内存。

你的代码块写死了 30 个列表项。如果数据是通过通信动态接收到的,要追加到列表中,最后再用列表进行图表绘制。追加列表元素用这个:
应该是图表默认最多显示 20 个点,你左右滑动图表处屏幕,可以拖动查看其他的点。

...to laptop
Enable USB Debugging on mobile device
On laptop, run adb reverse tcp:4000 tcp:4000
Use your custom port number instead of 4000
Now, on the mobile device, you can navigate to http://localhost:4000/, and it will actually connect to the laptop, not the mobile device

TransactionScope automatically escalating to MSDTC on some machines?
...s are not open at the same time, which would result in multiple "physical" TCP connections and thus require escalation.
I see some of your developers have SQL Server 2005 and others have SQL Server 2008. Are you sure you have correctly identified which ones are escalating and which not?

Why use deflate instead of gzip for text files served by Apache?
..., but a different algorithm for headers and checksum.
Now, the underlying TCP packets are already pretty reliable, so the issue here is not Adler 32 vs CRC-32 that GZIP uses.
Turns out many browsers over the years implemented an incorrect deflate algorithm. Instead of expecting the zlib header i...
