  • Call C (exposed) function from COBOL program

    - by Sunscreen
    Hi, Some time ago, I had created a DLL to be used in another C program. Basically I exposed specific functions by using the following within my dll: void __declspec(dllexport) MyFunc(myFirstArg, mySecondArg); Then I added an external file (MyExposedDll.h) with all exposed functions and structures to the new C program and included it: include MyExposedDll.h Now how can I use this dll (or mainly a dll) to a Cobol function? I need to expose a function that has two char* arguments and returns a boolean. Thanks, Sun

  • How to keep track of call statistics? C++

    - by tf.rz
    I'm working on a project that delivers statistics to the user. I created a class called Dog, And it has several functions. Speak, woof, run, fetch, etc. I want to have a function that spits out how many times each function has been called. I'm also interested in the constructor calls and destructor calls as well. I have a header file which defines all the functions, then a separate .cc file that implements them. My question is, is there a way to keep track of how many times each function is called? I have a function called print that will fetch the "statistics" and then output them to standard output. I was considering using static integers as part of the class itself, declaring several integers to keep track of those things. I know the compiler will create a copy of the integer and initialize it to a minimum value, and then I'll increment the integers in the .cc functions. I also thought about having static integers as a global variable in the .cc. Which way is easier? Or is there a better way to do this? Any help is greatly appreciated!

  • Url does not change in display when redirecting

    - by zsharp
    action: User/Details View: Details In my 'Details' view, a user can click on an actionlink that goes to the action :User/UserBehavior From which I again return a "Details" View. the url shows http://User/UserBehavior If I return redirectToAction to the Details action, I still get the "UserBehavior" action in the url. how do I redirect and present the new url of the action? isnt that the way its supposed to be? TO CLARIFY: WHEN YOU USE REDIRECTTOACTION, SHOULD THE URL IN THE BROWSER SHOW THE ORIGINAL ACTION OR THE ACTION YOU REDIRECTED TO?

  • Ruby on Rails - Calendar Display

    - by user335725
    We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

  • Call an external web service from a servlet

    - by pAkY88
    Hi, I'm developing a servlet that gets a name of a web service and could be forward the request to an external web service, for example: "http://www.webservice.com/..." I have build a response wrapper that intercept response output but I can't forward request to an external web service, it works only if I redirect the request to a servlet that is on same server. Example: request.getRequestDispatcher("aMyServlet").forward(request, response) IT WORKS request.getRequestDispatcher("http://www.webservice.com/...").forward(request, response) IT DON'T WORKS because Tomcat search "http://www.webservice.com/..." on the server as a local resource. How can I do external request? Thanks

  • Scroll returns to default after display:none in Chrome/IE

    - by Sam
    Here's the example: http://jsfiddle.net/sammy/RubNy/ Scroll down in the div container. Then click anywhere in the window to hide the element. Then click once more to show the element. You'll notice in Chrome/IE that the scroll is reset, but in Firefox, the scroll remains how you left it. Which is the standards behavior, Chrome/IE or Firefox? Should I report this to the Chrome issue tracker? Thanks in advance for any help on this, and happy new year, and thanks again, and cheers, and stuff. =D

  • Rails 2.3.5: flash[:notice] disappears after redirect_to call

    - by xyzman
    Here I've got two controller methods: def invite if request.post? begin email = AccountMailer.create_invite(@user,url) AccountMailer.deliver(email) flash[:notice] = "Invitation email sent to #{@user.email}" rescue #mail delivery failed flash[:error] = "Failed to deliver invitation" end redirect_to :action => :show, :id => @user.id end end and def show @title = "User #{@user.full_name}" end The problem is, when I send an invitation, and get redirected to ./show, I see no messages at all. If I change redirect_to to render, the message appears. Still, isn't it intended for flash to work in the immediate subsequent requests? BTW, I'm using Rails+Passenger setup, could it be so that redirected request goes to another application instance?

  • Display error when entire form is blank in CodeIgniter

    - by Joe
    I'm trying to create a fairly simple form that has a few checkboxes and input fields and a textarea. Nothing is required by itself; however, if 'A' checkbox is checked, then 'A' input field is required (and so on for the couple other checkboxes I have). I have the above functionality in place, but I'm having a tough time figuring out how to have an error returned if the form is submitted blank (since nothing is required by default). Does anyone know of an easy-ish solution for this? It seems like it should be so simple... Thanks

  • Refactoring and assessment

    - by neitony
    I'm using javascript to toggle the display state of some objects based on the time of day. A sample of the code is given below. I was wondering if anyone could give a suggestion as to how I can refactor this code while at the same time improving the logic. switch(tcode) { case 'eur' : eur.setAttribute('style', 'display:block; opacity:0.5'); us.style.display = 'none'; asia.style.display = 'none'; us_inactive.style.display = 'block'; asia_inactive.style.display = 'block'; break; case 'us' : us.style.display = 'block'; eur.style.display = 'none'; asia.style.display = 'none'; eur_inactive.style.display = 'block'; asia_inactive.style.display = 'block'; break; case 'asia' : asia.setAttribute('style', 'display:block; opacity:0.5'); us.style.display = 'none'; eur.style.display = 'none'; eur_inactive.style.display = 'block'; us_inactive.style.display = 'block';

  • Forcing LINQ to SQL to make one single call for all child rows

    - by zaph0d
    Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

    - by roman m
    I've had a problem with my styles not being applied after AJAX calls. My styles were not in the < HEAD section of the page, and they were only recognized by IE on initial Page_Load. If you know of any other ways to fix this problem, post them here. This is more of a reference, hope this helps some people.

  • Form variable does not refresh with ajax call

    - by ChrisOPeterson
    I'm building a simple email sending form and wanted to make it with ajax. The form submits correctly the first time but if you make any subsequent changes to the text in the form and then submit again then jquery does not pick up on the changes and posts the old data. Whats going on? <script type="text/javascript"> var $j = jQuery.noConflict(); $j(document).ready(function() { var submit_url = "mail_submit.php"; var send_email = $j("#sendemail"); send_email.click(function() { var form = $j("#post"); $j.post(submit_url, form.serialize(), function(data) { alert(data); }); }); });
