  • Way in over my head! (Dealing with better programmers)

    - by darkman
    I've just been hired to be part of a group that is developing in C++. Before, I've been coding on and off at my job for the past 11 years (some C, some Fortran, some C++). The coding I've done was mostly maintaining and adding new features to one of our systems. The code, being 10 years old, did not contain all the modern C++ stuff. Lo and behold, my new job is filled with programmers with 5-10 years experience of pure coding and they all use the most modern aspects of C++ (C++11, template, lambda, etc, etc). They are expecting someone with that same experience... Well, I've been working for 15 years total but when I looked at their code, I couldn't understand half of it! :-| Anyone been in that situation? What would you recommend?

  • How can I decrease my C# learning curve? [closed]

    - by MSU
    I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

  • How do I efficiently code both the client and server at the same time?

    - by liamzebedee
    I'm coding my game using a client-server model. When playing on singleplayer, the game starts a local server, and interacts with it just like a remote server (multiplayer). I have done this to avoid coding separate singleplayer and multiplayer code. I have just started coding and have encountered a major problem. Currently I'm developing the game in Eclipse, having all the game classes organized into packages. Then, in my server code, I just use all the classes in the client packages. The problem is, these client classes have variables that are specific to rendering, which obviously wouldn't be performed on a server. Should I create modified versions of the client classes to use in the server? Or should I just modify the client classes with a boolean, to indicate if its the client/server using it. Are there any other options I have? I just had a thought about maybe using the server class as the core class, then extending it with rendering stuff?

  • Why did visual programming never take off and what future paradigms might change that?

    - by Rego
    As the number of "visual" OS's such as Android, iOS and the promised Windows 8 are becoming more popular, it does not seem to me that we programmers have new ways to code using these new technologies, due to a possible lack in new visual programming languages paradigms. I've seen several discussions about incompatibilities between the current coding development environment, and the new OS approaches from Windows 8, Android and other tablets OS's. I mean, today if we have a new tablet, it's almost a requirement for coding, to have, for instance, an external keyboard (due it seems to me it's very difficult to program using the touch screen), exactly because the coding assistance is not conceived to "write" thousands of lines of code. So, how advanced should be the "new" visual programming languages paradigms? Which characteristics these new paradigms would be required?

  • How to find an array from parent array

    - by Me-and-Coding
    Hi, I am using below code to find an array inside parent array but it is not working that is retuning empty even though the specified key exits in the parent array. $cards_parent = $feedData['BetradarLivescoreData']['Sport']['Category']['Tournament']['Match']; $cards = array(); foreach($cards_parent as $key => $card) { if ($key === 'Cards') { $cards[] = $cards_parent[$key]; break; } } Do you know any array function that will search parent array for specified key and if found it will create an array starting from that key. Thanks

  • Admin auto generation

    - by Me-and-Coding
    Hi, I create custom CMS sites and then go ahead for the backend/admin side. Is there any tool out there to automatically create admin side of my sites, for example, based on table relationships or whatever customization we may put in place. PHPMaker seems to claim something like what i ask for but i have not used it. Any tool out there to auto-create admin side or PHPMaker is up to the point? Thanks

  • Adding Days To Date in SQL

    - by Coding Noob
    I am trying to get data from my Database of those who have upcoming birth days in next few days(declared earlier) it's working fine for days but this query will not work if i add 24 days to current date cause than it will need change in month. i wonder how can i do it declare @date int=10, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) This query works fine but it only checks date between 8 & 18 but if i use it like this declare @date int=30, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) it will return nothing since it require addition in month as well If I Use it like this declare @date int=40, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEADD(DD,@date,GETDATE()) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) than it will return results till the last of this month but will not show till 18/12 which was required

  • Unable to delete inherited entity class in EF4

    - by Coding Gorilla
    I have two entities in an EF4 model (using Model First), let's call them EntityA and EntityB. EntityA is marked as abstract, and EntityB inherits from EntityA. They are similar to the following: public class EntityA { public Guid Id; public string Name; public string Uri; } public class EntityB : EntityA { public string AnotherProperty; } The generated database tables look as I would expect them, with EntityA as on table, and then another table like: EntityA_EntityB Id (PK, FK, uniqueidentifier) AnotherProperty (varchar) There is a foreign key constraint on EntityA_EntityB that references EntityA's Id property, no cascades are configured (although I did try changing these myself). The problem is that when I attempt to do something like: Context.DeleteObject(EntityA_EntityB); EF attempts to delete the EntityA_EntityB table record before deleting the EntityA table record, which of course violates the foreign key constraint on EntityA_EntityB table. Using EFProfiler I see the following commands being sent to the database: delete [dbo].[EntityA_EntityB] where (([Id] = '5c02899f-09ea-2ed9-d44b-01aef80f6b64' /* @0 */) followed by delete [dbo].[EntityA] where ([Id] = '5c02899f-09ea-2ed9-d44b-01aef80f6b64' /* @0 */) I'm completely stumped as to how to get around this problem. I would think the EF should know that it needs to delete the base class first, before deleting the inherited class. I know I could do some triggers or other database type solutions, but I'd rather avoid doing that if I can. All my classes are POCO built using some customized T4 templates. I don't want to paste in a lot of extraneous code, but if you need more information I'll provide what I can.

  • SQL Scenario of allocating ids to user

    - by Enjoy coding
    Hi, I have an sql scenario as follows which I have been trying to improve. There is a table 'Returns' which is having ids of the returned goods against a shop for an item. Its structure is as below. Returns ------------------------- Return ID | Shop | Item ------------------------- 1 Shop1 Item1 2 Shop1 Item1 3 Shop1 Item1 4 Shop1 Item1 5 Shop1 Item1 There is one more table Supplier with Shop, supplier and Item as shown below. Supplier --------------------------------- Supplier | Shop | Item | Volume --------------------------------- supp1 Shop1 Item1 20% supp2 Shop1 Item1 80% Now as you see supp1 is supplying 20 % of total item1 volume and supp2 is supplying 80% of Item1 to shop1. And there were 5 return of items against the same Item1 for same Shop1. Now I need to allocate any four return IDs to Supp1 and remaining one return Id to supp2. This allocation of numbers is based on the ratio of the supplied volume percentage of the supplier. This allocation varies depending on the ratio of volume of supplied items. Now I have tried a method of using RANKs as shown below by use of temp tables. temp table 1 will have Shop, Return Id, Item, Total count of return IDs and Rank of the return id. temp table 2 will have shop, Supplier, Item and his proportion and rank of proportion. Now I am facing the difficulty in allocating top return ids to top supplier as illustrated above. As SQL doesnt have loops how can I achieve this. I have been tying several ways of doing this. Please advice. My environment is Teradata (ANSI SQL is enough). Thanks in advance.

  • Any dynamic database frontend tool from which you can update directly?

    - by Enjoy coding
    Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

  • Merging multiple docx files to one

    - by coding
    I am developing a desktop application in C#. I have coded a function to merge multiple docx files but it does not work as expected. I don't get the content exactly as how it was in the source files. A few blank lines are added in between. The content extends to the next pages, header and footer information is lost, page margins gets changed, etc.. How can I concatenate docs as it is without and change in it.Any suggestions will be helpful. This is my code. public bool CombineDocx(string[] filesToMerge, string destFilepath) { Application wordApp = null; Document wordDoc = null; object outputFile = destFilepath; object missing = Type.Missing; object pageBreak = WdBreakType.wdPageBreak; try { wordApp = new Application { DisplayAlerts = WdAlertLevel.wdAlertsNone, Visible = false }; wordDoc = wordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing); Selection selection = wordApp.Selection; foreach (string file in filesToMerge) { selection.InsertFile(file, ref missing, ref missing, ref missing, ref missing); selection.InsertBreak(ref pageBreak); } wordDoc.SaveAs( ref outputFile, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); return true; } catch (Exception ex) { Msg.Log(ex); return false; } finally { if (wordDoc != null) { wordDoc.Close(); } if (wordApp != null) { wordApp.DisplayAlerts = WdAlertLevel.wdAlertsAll; wordApp.Quit(); Marshal.FinalReleaseComObject(wordApp); } } }

  • How to shrink the Remote Desktop Connection Bar in Windows?

    - by Some Noob Student
    Ever since FireFox 4, page tabs have been moved to the top of the window. This gets pretty irritating when surfing the net through a remote desktop session. Often when I want to switch tabs, if I accidentally move my mouse a little to much to the top, I get the remote desktop connection bar blocking the tabs instead, then I'd have to wait a few frustrating seconds before it disappears again. So, are there any methods to shrink or shorten the remote desktop connection bar or delay the appearance of it?

  • Script/ Macro in Excel, by clicking on a cell

    - by Noob Doob
    There's something I want to do in Excel 2010. Specifically, I want to be able to make the open sheet load data from a text file, by clicking -important- on a cell of the current open worksheet. So my specific needs are: If it is possible in some way, to start a macro/script by clicking on a cell. About the script/macro: What would be the preferable, by your opinion, way of implementation. And more specifically, how to automatically import the data needed, only by clicking, without having to continually specify the desirable .txt file each time, only 1 time at max, at start or by using a custom "initalization/configuration" file.

  • Drupal 7: One-time user account

    - by Noob
    I'm going to create a survey in Drupal 7 with the webform module, installed on a debian system which may be adapted in every way. The users (personally known, approx. 120) doing that survey will walk into a room and complete the survey in browsers on different computers. After that, they'll leave the room and other persons will enter, complete the survey on the same computers and so on. Each user may enter only one submission. The process needs to be anonymous, i. e. I mustn't have any idea of who did wich submission. My current solution is to generate random one-time-passwords and hand out one password per user (without noting who got which password). Within the survey there will be a password field where the one-time-password is entered. The value is checked by webform to be unique. I'll get the data via csv or Excel and verify the passwords manually in excel by comparing them to the list of valid passwords. The problem is: I don't like the idea of manually generating the password list, copying it to excel and doing a manual check. That's a good idea for one-time-use, but we're going to repeat the survey every once in a while. I'd rather generate one-time-logins (like user0001/fdlkjewf, user0002/dfrefnnr, ...) for each survey, hand them out to the users and let drupal/debian/whatever check whether a submission is valid or not. Do you have any idea how to batch-generate about 120 users with one-time-passwords in Drupal 7 and verify that each user may submit the form only once? Do you even have a better idea how to accomplish the task within the intranet? Thank you for your help.

  • vmware player won't run on CentOS due to missing /dev/vmmon, what could be the problem?

    - by Graphics Noob
    So I've tried installing vmware player 3.1.4 and 3.1.3 and both times had the same problem, when I try to load a VM I get the error "Could not open /dev/vmmon". When I ls /dev/ I can see there is no "vmmon" device present. When I try running: sudo /etc/init.d/vmware start I get the output: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [FAILED] which shows that the Virtual Machine Monitor fails to load. I tried following the advice on this site and ran vmware-modconfig --console --install-all I notice during the compilation there are no errors, but at the end I get the message: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [ OK ] Unable to start services Out of curiousity I tried: sudo /sbin/insmod /lib/modules/2.6.18-238.9.1.el5xen/misc/vmmod.ko But got the error message: insmod: error inserting 'vmmon.ko': -1 Invalid module format I have a feeling this may be the root of the problem, but I don't know what could be causing it or how to fix it.

  • Does there exist video chat software which works over a LAN between different types of devices?

    - by Graphics Noob
    What I'm trying to do is set up a local area network, without internet access, which allows the users to video chat with each other. The connected devices will include Linux and Android devices, so software which will run with just those two types of systems will work, although running through a browser would be optimal. The most promising lead I've found so far is camfrog, which has a video-chat app for android and a video chat server for linux. The problem is that the documentation for the server is non-existant, and I don't know if the android app can directly connect to the video chat server over a LAN or if it can only connect to camfrog's video chat server over the internet.
