  • How can I retrieve all the returned variables from a function?

    - by user1447941
    import random def some_function(): example = random.randint(0, 1) if example == 1: other_example = 2 else: return False return example, other_example With this example, there is a chance that either one or two variables will be returned. Usually, for one variable I'd use var = some_function() while for two, var, var2 = some_function(). How can I tell how many variables are being returned by the function?

  • Is there any C/C++ editor in Linux that shows errors while typing

    - by MetallicPriest
    The Visual C++ editor has a great feature which is that it underlines errors with a red line while typing the code. So for example, if you are using a variable that is not declared, it will underline it with a red curly line. In this way, the programmer can resolve a lot of errors while typing and doesn't have to wait for compiling for noticing them. Now my question is, is there any editor for Linux that has this great feature?

  • Workflow for reading and writing files

    - by AIR_PhillipSenn
    In Workflow for reading and writing files the authors use these two lines of code: var file = air.File.documentsDirectory; file = file.resolvePath("AIR Test/testFile.txt"); But I think that it's using one variable for two different meanings, isn't it? Wouldn't it be better to write them as: var myDocumentsDirectory = air.File.documentsDirectory; var myTestFile = myDocumentsDirectory.resolvePath("AIR Test/testFile.txt");

  • Thread-safe get (accessor method)

    - by sonofdelphi
    I'm currently using the following code for thread-safe access of a variable. int gnVariable; void getVariableValue(int *pnValue) { acquireLock(); //Acquires the protection mechanism *pnValue = gnVariable; releaseLock(); //Releasing the protection mechanism } I would like to change my API signature to a more user-friendly int getVariableValue(void); How should I rewrite the function - such that the users of the API don't have to bother about the locking/unlocking details?

  • How to navigate around a '[' in JSON.

    - by Kyle
    I'm new to JSON and moving around in it in jQuery. I'm fine until I hit a '[', as in: "gd$when": [{ "startTime": "2006-11-15", "endTime": "2006-11-17", "gd$reminder": [{"minutes": "10"}] }], I tried to do a eventTime = event["gd$when"]["startTime"]; to get to the 'startTime' (Yes, event is the variable for ajax stuff, it's all working fine until I hit the '[') Thanks for any help.

  • JS Split ( ) to check if substring exists in Array

    - by Javacadabra
    I have an array of products that are stored as Strings in this format productname:quantity. The issue I am running into is that if a user adds one product with a quantity of x it is inserted into the array as it should. However, if they then decide to add more of a particular product a new entry is made into the array instead of checking if the product already exists and adjusting the quantity to the new value. oldQty + newQty. For example this is my array: ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1"] If I add another PALLET CARDS product it creates a new entry rather than updating the quantity of the existing item to 2. New array ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1","PALLET CARDS:1"] I would like the array to end up like this: - updating the quantity ["CBL202659/A:1","OUTER9:1","PALLET CARDS:2"] Currently this is my code: I use the split() method to seperate the String where a colon occurs and store the product name and quantity in two seperate variables. $(".orderBtn").click(function(event){ //Show the order Box $(".order-alert").show(); event.preventDefault(); //Create the Array var productArray = []; //Get reference to the product clicked var stockCode = $(this).closest('li').find('.stock_code').html(); //Get reference to the quantity selected var quantity = $(this).closest('li').find('.order_amount').val(); var item = stockCode + ":" + quantity; var itemCheck = stockCode + ":"; if(quantity == 0){ console.log("Quantity must be greater than 0") }else{ //If no Cookie exists, create one and add the Array if ($.cookie('order_cookie') === undefined) { console.log("CREATE NEW COOKIE"); //Add items to Array productArray.push(item); //Add Array to Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); //If the Cookie already exists do this } else { productArray = JSON.parse($.cookie('order_cookie'));//get ref to array if(productArray.indexOf(itemCheck)!= -1){//It exists so update qty console.log("EXISTS... updating item: " + itemCheck); //var index = productArray.indexOf(item); //var update = productArray[index].split(":"); //var name = update[0]; //var oldQty = update[1]; //console.log(name + ":" + oldQty); //productArray[index] = item; }else{//It does not exist, so add to array console.log("Does not exist... adding new item: " + item); //Append items onto the Array productArray.push(item); } //Update the Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); console.log($.cookie('order_cookie')); } //Display the number of items in the Array in the Order Box $('#order_counter').html(productArray.length); } }); I suppose the real question I am asking here, is if it is possible to search the array for a subString - containing productname: ??

  • Is it possible to start (and stop) a thread inside a DLL?

    - by Jerry Dodge
    I'm pondering some ideas for building a DLL for some common stuff I do. One thing I'd like to check if it's possible is running a thread inside of a DLL. I'm sure I would be able to at least start it, and have it automatically free on terminate (and make it forcefully terminate its self) - that I can see wouldn't be much of a problem. But once I start it, I don't see how I can continue communicating with it (especially to stop it) mainly because each call to the DLL is unique (as far as my knowledge tells me) but I also know very little of the subject. I've seen how in some occasions, a DLL can be loaded at the beginning and released at the end when it's not needed anymore. I have 0 knowledge or experience with this method, other than just seeing something related to it, couldn't even tell you what or how, I don't remember. But is this even possible? I know about ActiveX/COM but that is not what I want - I'd like just a basic DLL that can be used across languages (specifically C#). Also, if it is possible, then how would I go about doing callbacks from the DLL to the app? For example, when I start the thread, I most probably will assign a function (which is inside the EXE) to be the handler for the events (which are triggered from the DLL). So I guess what I'm asking is - how to load a DLL for continuous work and release it when I'm done - as opposed to the simple method of calling individual functions in the DLL as needed. In the same case - I might assign variables or create objects inside the DLL. How can I assure that once I assign that variable (or create the object), how can I make sure that variable or object will still be available the next time I call the DLL? Obviously it would require a mechanism to Initialize/Finalize the DLL (I.E. create the objects inside the DLL when the DLL is loaded, and free the objects when the DLL is unloaded). EDIT: In the end, I will wrap the DLL inside of a component, so when an instance of the component is created, DLL will be loaded and a corresponding thread will be created inside the DLL, then when the component is free'd, the DLL is unloaded. Also need to make sure that if there are for example 2 of these components, that there will be 2 instances of the DLL loaded for each component. Is this in any way related to the use of an IInterface? Because I also have 0 experience with this. No need to answer it directly with sample source code - a link to a good tutorial would be great.
