visa is a Go library. visa has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Package visa wraps National Instruments VISA (Virtual Instrument Software Architecture) driver. The driver allows a client application to communicate with most instrumentation buses including GPIB, USB, Serial, and Ethernet. The Virtual Instrument Software Architecture (VISA) is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, serial (RS232/RS485), Ethernet/LXI, and/or USB interfaces. The package is low level and, for the most part, is one-to-one with the exported C functions it wraps. Clients would typically build an instrument specific driver around the package but it can also be used directly. Supported Platforms: * Linux * OS X * Windows.

            SQL Help, Splitting Tax by Tenders
            Asked 2022-Mar-29 at 16:14

            I have a Point of Sale system where all checks and tender details exist in a single table. I'm trying to write a SQL query in a way that I can see check totals by tenders to reconcile with cash flow and bank statements. Unfortunately the schema is not mine and can't change it.

            One problem I ran into is that there are cases where one check has multiple transactions involving various tenders, therefore I need to do implement (business set) rules to allocate taxes evenly. Those rules might change in the future to say, allocate taxes to CC first if any, so I need to built in some flexibility.

            The SQL table looks like this:

            CheckID LineType TenderName LineTotal Tax 1 ItemSold 5.00 0.25 1 TenderTotal Cash 5.25 2 ItemSold 10.00 0.50 2 TenderTotal Cash 5.00 2 TenderTotal VISA 5.50 3 ItemSold 10.00 0.25 3 ItemSold 10.00 0.25 3 TenderTotal AMEX 10.25 3 TenderTotal VISA 10.25 4 ItemSold 10.00 0.50 4 TenderTotal Cash 20.00 4 TenderTotal Cash -9.50

            The resulting report needs to have one row per tender, with tax equally distributed among check tenders, and net revenue being the difference between total sale and tax.

            TenderName TotalSale NetRevenue TaxCollected Cash 20.75 19.75 1.00 VISA 15.75 15.25 0.50 AMEX 10.25 10.00 0.25

            I tried using Select with Exists, also CTE and recursive CTEs, but can't quite figure it out how to do the tax part cleanly. Any other SQL tricks I could try?

            We are using SQL Server 2012 at the moment, but have plans in plan to upgrade to 2016 in the near future.

            Since your function "..has many optional parameters" and passengers parameter requires a dictionary as an input, I would suggest you create a Pydantic model, where you define your parameters, and which allows sending your data in JSON form and getting them validated, as well as converting the model to a dictionary using the dict() method.

            SQLite: How to create a new table from another table when the columns are disparate but linked by one column
            Asked 2022-Mar-22 at 20:33

            Say I have a new table like such where there is no values yet:

            key uuid dog cat deer etc

            and i have a populated table like such where it has values that i want to correlate to the new empty table:

            key uuid format status 1 uuid1 dog hairy 2 uuid1 cat fluffy 3 uuid2 dog shaved 4 uuid3 deer smooth

            what i want to do is take each "format" from table 2 and create a new column in table 1 where "status" from table 2 is the value of the new "format" column in table one. Here is what i want the table to look like assuming the above tables are what im working with:

            key uuid dog cat deer etc 1 uuid1 hairy fluffy null other value 2 uuid2 shaved null null other value 3 uuid3 null null smooth other value

            The extra tricky part is in table 2, uuid1 can have more or less "format" values than say uuid2 and visa versa continuing on to like 50k uuids so i need to fill the other columns with a null or falsey value

            Is this possible or am I working with too ridiculous of data to make it happen?

            Since you have created the new table this means that you already know the possible values of the column format.
            In this case you can use conditional aggregation to populate the table:

            Your React Native code looks normal. You may want to confirm what your backend is doing when it receives that PaymentMethod.

            The error message "No such PaymentMethod..." is a common error when your backend uses a secret key that belongs to a different Stripe Account than your frontend's publishable key.

            I have followed a tutorial "Create HTML Form that Moves through RecordSet on Google Sheets" done by Code With Curt. https://www.youtube.com/watch?v=V9ptq7tZV50&t=152s

The form shows up OK from the custom menu but it is not populating with the data from the sheet. The only error I can see is in the console which says "Uncaught ReferenceError: loadRecords is not defined" I have double checked the variable and function names but just can't see the error.

            Regarding the specific error, the parenthesis are missing in two lines:

            var nextRecord = Number record + 1;
            var previousRecord = Number record - 1;

            Correct syntax

            var nextRecord = Number(record) + 1;
            var previousRecord = Number(record) - 1;

            As mentioned in the Yuri's answer, the video that you used looks to have some problems. From my point of view it's obsolete, one hint is that it's using the now called "Classic Editor" instead of the current default editor. It's weird that the comment with the code was removed, next time start with a more recent example and once you have learned how to debug and learned the differences between the "old" Google Apps Script and the new (i.e. old runtime based on Mozilla Rhino, and the new runtime Chrome V8), go to old tutorials / examples.

            P.S. It might be possible that if you are using new editor that your project is using the new runtime, if you want to try the code as is in the video, try enabling the Rhino runtime, for details see https://developers.google.com/apps-script/guides/v8-runtime.

            A clarification on the named requirements for containers
            Asked 2022-Jan-01 at 16:27

            I am trying to get to grips with the specifics of the (C++20) standards requirements for container classes with a view to writing some container classes that are compatible with the standard library. To begin looking into this matter I have looked up the references for named requirements, specifically around container requirements, and have only found one general container requirement called Container given by the standard. Reading this requirement has given my two queries that I am unsure about and would like some clarification on:

            1. The requirement for the expression a == b for two container type C has as precondition on the element type T that it is equality comparable. However, noted later on the same page under the header 'other requirements' is the explicitly requirement that T be always equality comparable. Thus, on my reading the precondition for the aforementioned requirement is redundant and need not be given. Am I correct in this thinking, or is there something else at play here that I should take into account?

            2. I was surprised to see explicit requirements on T at all: notably the equality comparable requirement above and the named requirement destructible. Does this mean it is undefined behaviour to ever construct standard containers of types failing these requirements, or only to perform certain standard library function calls on them?

            Apologies if these two questions sound asinine, I am currently trying to transition my C++ knowledge from a place of having a basic understanding of how to use features to a robust understanding so that I may write good generic code. Whilst I am trying to use (a draft of) the standard to look up behaviour where possible, its verbiage is oft too verbose for me to completely understand what is actually being said.

            In an attempt to seek the answer I cooked up a a quick test .cpp file to try an compile, given below. All uncommented code compiles with MSVC compiler set to C++20. All commented code will not compile, and visa versa all uncommented code will. It seems that what one naively thinks should work does In particular:

            • We cannot construct any object without a destructor, though the objects type is valid and can be used for other things (for example as a template parameter!)
            • We cannot create an object of vector, where T has no destructor, even if we don't attempt to create any objects T. Presumably because creating the destructor for vector tries to access a destructor for T.
            • We can create an object of type vector, T where T has no operator ==, so long as we do not try to use operator ==, which would require T to have operator ==.

            However, just because my compiler lets me make an object of vector where T is not equality-comparable does not mean I have achieved standards compliant behaviour/ all of our behaviour is not undefined - which is what I want I concerned about, especially as at least some of the usual requirements on the container object have been violated.

            Code:

            ...

            Answered 2021-Dec-30 at 04:32

            If the members of a container are not destructible, then the container could never do anything except add new elements (or replace existing elements). erase, resize and destruction all involve destroying elements. If you had a type T that was not destructible, and attempted to instantiate a vector (say), I would expect that it would fail to compile.

            As for the duplicate requirements, I suspect that's just something that snuck in when the CppReference folks wrote that page. The container requirements in the standard mention (in the entry for a == b) that the elements must be equality comparable.
