问题 I am new to this site and this is my first question. I am trying to query the "Seattle Real Time Fire 911 Calls" database from the Socrata Seattle Open Data site: https://data.seattle.gov/Public-Safety/Seattle-Real-Time-Fire-911-Calls/kzjm-xkqj.

问题 I'm trying to write a little script to control two raspberry pi's gpio output pins based on two factors: the state of GPIO.input.17 and the time of day. I would like gpio.output.23 and gpio.output.25 to be low when gpio.input.17 is low. I would like gpio.output.23 to go high when gpio.input.17 is high and the time is between 0700-2159. I would like gpio.output.25 to go high when gpio.input.17 is high and the time is between 2200-0659. so far, the code i've put together looks like this: #!/usr

问题 I have an SSIS package that imports Excel files. Inside the package, I have a Script task that checks whether the Excel file exists or not before executing the Excel import process. I am unable to execute the package when the Excel file doesn't exist because of the AcquireConnection error. How can I prevent the package from executing when there is no Excel file available for import? 回答1: Perform the following steps to avoid the package from failing. Set the ValidateExternalMetadata property

问题 I'm trying to add a wrapper around DateTime to include the time zone information. Here's what I have so far: public struct DateTimeWithZone { private readonly DateTime _utcDateTime; private readonly TimeZoneInfo _timeZone; public DateTimeWithZone(DateTime dateTime, TimeZoneInfo timeZone) { _utcDateTime = TimeZoneInfo.ConvertTimeToUtc(DateTime.SpecifyKind(dateTime, DateTimeKind.Unspecified), timeZone); _timeZone = timeZone; } public DateTime UniversalTime { get { return _utcDateTime; } }

问题 I am currently trying to parse a string that is obtained from an xml that is downloaded from the web every few minutes. The string looks like this: Thu Jul 12 08:39:56 GMT+0100 2012 At first I just did a string.split and took out everything after the time ( GMT+0100 2012 ) and inserted 2012 after the date. This worked great until the date changed to: Thu Jul 12 08:39:56 GMT+0000 2012 So I would like to dynamically pasre the GMT+ whatever as they send me that string in c#. Any advice would be
