synchronous

问题 Is there any way of freezing the browser window intentionally like alert , confirm and prompt (in short: "acp") does? I want to show a modal dialog with custom css instead of the native popups for "acp" but also want to have the ability to freeze the browser until I have users feedback just like "acp". But man, why? This is bad practice (uh I have to downvote)! So when it is bad practice - then why does "acp" actually offer this synchronous behavior? Because in some particular scenarios its

问题 I'm writing a NodeJS script that calls a bunch of APIs via GET (using request from npm) and saves the responses in a JSON file. I'm using a for to loop through IDs to pass to the APIs, but I'm having trouble putting in a delay between call bursts so I don't spam the API server and make it mad at me (rate limiting). Does anyone know how to do this? My current code (without any delay): var fs = require('fs'); var request = require('request'); // run through the IDs for(var i = 1; i <= 4; i++) {

问题 I have a large scale C# solution with 40-ish modules. I'm trying to convert a service used solution-wide from synchronous to asynchronous. the problem is I can't find a way to do so without changing the signature of the method. I've tried wrapping said asynchronous desired operation with Task but that requires changing the method signature. I've tried changing the caller to block itself while the method is operating but that screwed my system pretty good because it's a very long calling-chain

问题 I'd like to run all of my functions synchronously. But if I execute something like the code below the response is sent back before the return value is assigned. index.js exports.cfTest = (req, res) => { try { result = columnCount( 'project','dataset','table' ); console.log('sending response'); res.send('<OUTPUT>' + result + '</OUTPUT>'); } catch (err) { res.status(500).send('<ERROR>' + err + '</ERROR>'); } }; function columnCount(projectId, bqDataset, bqTable) { const BigQuery = require('

问题 I have two TSQL EXEC statements EXECUTE (N'MyDynamicallyGeneratedStoredProcedure') -- return 0 on success SELECT @errCode = @@ERROR ; IF (@errCode = 0) BEGIN EXEC 'A Sql Statement using ##temptable created from first', @returnValue END How do I make the two EXEC's synchronous? ; Right now the second EXEC does not wait for the first EXECUTE to complete. I tried issuing a WaitFor Delay, It waits but the second EXEC statement is never returing back. Thanks. Update, Here is more info: First

问题 I'm making the classic atari snake game in python3 using Pygame. I want to spawn a subprocess to listen for key strokes so that whenever the player enters a key (UP, DOWN, LEFT, or RIGHT), the subprocess sends the parent process the key. But this pipe should not be blocking, so that the snake can travel in the direction it was traveling until the key is received. I found Python's official documentation on multi-processes, but it does not describe the behavior I want, or at least doesn't

问题 Is there any way to synchronously execute a thread made with Lwt library? To be specific, I am trying to run a series of post requests to a server that compute some value and returns a result. Based on answers provided to this question: How do I make a simple GET request in OCaml? I can make it with either low level approach (sockets) or using the Cohttp library. The low level approach has the advantage of being immediate and straightforward but I would rather stick to the Cohttp (no need for

问题 So basicly the ReadLine() method just hangs right on the last output line. I dont need to end the process. The main goal is to do "cmd-shell" with stdin and stdout (in variables/Printed out). If the same can be achieved with async methods, please, leave it in comments. Thanks in advance. { Process p = new Process() { StartInfo = new ProcessStartInfo("cmd") { UseShellExecute = false, RedirectStandardInput = true, RedirectStandardError = true, RedirectStandardOutput = true, CreateNoWindow =
