  • How do I erase printed characters in a console application(Linux)?

    - by Binny V A
    Hi all, I am creating a small console app that needs a progress bar. Something like... Conversion: 175/348 Seconds |========== | 50% My question is, how do you erase characters already printed to the console? When I reach the 51st percentage, I have to erase this line from the console and insert a new line. In my current solution, this is what happens... Conversion: 175/348 Seconds |========== | 50% Conversion: 179/348 Seconds |========== | 52% Conversion: 183/348 Seconds |========== | 54% Conversion: 187/348 Seconds |=========== | 56% Code I use is... print "Conversion: $converted_seconds/$total_time Seconds $progress_bar $converted_percentage%\n"; I am doing this in Linux using PHP(only I will use the app - so please excuse the language choice). So, the solution should work on the Linux platform - but if you have a solution that's cross platform, that would be preferable.

  • For each element A[i] of array A, find the closest j such that A[j] > A[i]

    - by SamH
    Hi everyone. Given : An array A[1..n] of real numbers. Goal : An array D[1..n] such that D[i] = min{ distance(i,j) : A[j] > A[i] } or some default value (like 0) when there is no higher-valued element. I would really like to use Euclidean distance here. Example : A = [-1.35, 3.03, 0.73, -0.06, 0.71, -0.21, -0.12, 1.49, 1.41, 1.42] D = [1, 0, 1, 1, 2, 1, 1, 6, 1, 2] Is there any way to beat the obvious O(n^2) solution? The only progress I've made so far is that D[i] = 1 whenever A[i] is not a local maxima. I've been thinking a lot and have come up with NOTHING. I hope to eventually extend this to 2D (so A and D are matrices).

  • attaching multiple files to a domain class

    - by Emyr
    I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

  • Repositioning a label with mouseevents to anywhere on the screen

    - by user2947295
    I've created a label and used setPixmap to attach a .png image to the label. I've also setWindowFlags to disable the title bar and create a frameless window. Because I've disabled those, it also disables the ability to drag anything around, so I want to create mouseevents (unless there's a better method) to position my label anywhere on the screen exactly like dragging the frame of a window. How would I do that? An example and brief explanation would be greatly appreciated.

  • How to change the value of progressbar in C#?

    - by shekhar
    Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,

  • Custom QAction/QMenu for mouse button detection

    - by voodoogiant
    I'm trying to create a popup menu, where I can detect the mouse button that was pressed for a given item. I've created a custom QAction already to build my QMenu, but the triggered signal when the menu item is pressed doesn't provide a QMouseEvent for me to query the button pressed. Also, I'm setting the a status tip for each QAction, which appears in the status bar when I mouse over it, but it stays even after I close the QMenu. Is this normal behavior?

  • "Slice" out one element from a python dictionary

    - by BCS
    I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

  • strstr and occurrences to match

    - by Mike
    I have several possible occurrences to test with strstr. if ((a = strstr(string, "FOO")) != NULL || (a = strstr(string, "BAR")) != NULL || (a = strstr(string, "FOO2")) != NULL ||(a = strstr(string, "BAR2")) != NULL || (a = strstr(string, "FOO3")) != NULL ||(a = strstr(string, "BAR3")) != NULL) // do something and then based on the occurrence found I need to do var = strlen("THE_ONE_MATCHED_ABOVE"); What would be a good way to do this without using lots of if statements?

  • PHP Simplify a ternary operation

    - by Obay
    In PHP, is there a way to simplify this even more, without using an if()? $foo = $bar!==0 ? $foo : ''; I was wondering if there was a way to not reassign $foo to itself if the condition is satisfied. I understand there is a way to do this in Javascript (using &&, right?), but was wondering if there was a way to do this in PHP.

  • How much benefit do you get from working with other developers?

    - by SnOrfus
    For whatever reason I've only ever worked solo. The job that I have now, I was under the impression that I was being hired to work underneath a senior developer and that I'd be able to learn from them/their code. This was actually one of the conditions that I had when I accepted the position (that and I was broke and needed the cash - so I would have likely taken it anyway). As it turns out, the intention of management was for me to replace that senior developer because they were contracted and relatively expensive. The question I have is, though I've learned a lot in the 2 short years I've been here, am I potentially seriously stunting my learning/progress working solo instead of working at a company with other developers?

  • How to stop a MFC/win32 control re-painting

    - by John
    I have a CRichEditCtrl, and an algorithm works on its contents in-place, iterating through the contents and making changes. This seems to cause it to re-paaint every time, which causes flickering and a noticeable time to complete the operation, especially if the control starts scrolling. I wondered if there's a neat way for me to stop it repainting for a period. It's actually a custom subclass of CRichEditCtrl in use so I was thinking something like: void MyCustomEditCtrl::DoAlgorithm() { enableRepaint(false); ... //to the actual work ... enableRepaint(true); } What's the neatest approach? A custom on-paint handler which does nothing when an operation is in progress? Or can repainting actually be disabled?

  • Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

    - by h_power11
    Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

  • Ruby: Streaming large AWS S3 object freezes

    - by Peter
    Hi, I am using the ruby aws/s3 library to retrieve files from Amazon S3. I stream an object and write it to file as per the documentation (with debug every 100 chunks to confirm progress) This works for small files, but randomly freezes downloading large (150MB) files on VPS Ubuntu. Fetching the same files (150MB) from my mac on a much slower connection works just fine. When it hangs there is no error thrown and the last line of debug output is the 'Finished chunk'. I've seen it write between 100 and 10,000 chunks before freezing. Anyone come across this or have ideas on what the cause might be? Thanks The code that hangs: i=1 open(local_file, 'w') do |f| AWS::S3::S3Object.value(key, @s3_bucket) do |chunk| puts("Writing chunk #{i}") f.write chunk.read_body puts("Finished chunk #{i}") i=i+1 end end

  • VS2010 patch: why it's take so much time to install it? [closed]

    - by Mendy
    Visual Studio 2010 RC has a few of patches release. For more information about them take a look here. What I'm expect from patch program, is to replace a few dll's of the program to a new fixed version of them. But when I run each of this 3 patches, they take a lot of time (5 minutes each), and you think that the program was frozen because the progress bar stay on the begging. This is question may not be so important, but it really interesting me to know, why this happens? It's really confusing to see that each VS2010 (or Microsoft in general) is frozen to 4-5 minutes.

  • Is there a way to get the current UIEvent being handled?

    - by not-
    I'm working in a class that is a delegate of another class; this other class is in a third-party library that I'd like to avoid changing if at all possible. The original class is handling a -touchesEnded event, and is delegating responsibility to me, but it doesn't pass the UIEvent itself to me. Is there a way to get a handle to the current event in progress? It's a double-tap handler, and all that is passed to me is the view being touched, and the point at which the touch occurred. I want to know exactly how many touches are involved in the event. Thanks! randy
