  • Visual Basic and C++

    - by Hamdy Elgammal
    Hello there, I was reading a little into Visual Basic and it seemed a rather simple way to implement some GUI...So I was looking for a way to interface my C++ code to a Visual Basic snippet of code. For example, receive input from a Visual Basic app and send it over to C++ code to continue the logic of the program based on the input of that event.

Example: Input Output ---------------- +1 +1 1 +1 -1 -1 It will get only numeric input. function formatNum($num) { # something here..perhaps a regex? } This function is going to be called several times in echo/print so the quicker the better.

    - by Ajith
    I was wondering how to save PHP variables to a txt file and then retrieve them again. Example: There is an input box, after submitted the stuff that was written in the input box will be saved to a text file. Later on the results need to be brought back as a variable. So lets say the variable is $text I need that to be saved to a text file and be able to retrieve it back again. Hope it makes sense, Thanks in advance!!!

  • JavaScript function to validate an integer value

    - by Psyche
    Hello, I'm building a shopping cart and I would like to use a JavaScript function to validate user input when entering the quantity value in the quantity text input. I would like to allow the entering of integer values only (no floats, no other characters). I know that I can apply this function using onKeyUp event and also I found isNaN() function, but it returns true even for floats (which is not ok). Can you guys help me out with this one? Thanks.

  • Can we turn on the iphone's number keyboard WITHOUT using type=number?

    - by Simple As Could Be
    I'm making a webapp, and I'd like an input field to show the Iphone's number keypad. I understand that type=number will make the keypad show the way I'd like. The trouble is that type=number does not support placeholder text. So if I would like this: Expiration Date: [eg: 2010] I can not get it to work, and also show the right keyboard. Is there a way to force the iphone keyboard into number mode without using the number input type?

  • Check Avaibility of a page before loading using jquery/ajax

    - by overcomer
    Is it possible check the Accessibility of a page before loading it? I have a form, running on mobile device using wireless connection. The problem is: not always this connection is avaible and i would like to alert the user when is doing a submit or an unload of the page. The problem is that the page contains elements doing redirect like this: <input type="button" value="MyText" onClick="script1;script2;...window.location='mylocation" /> If the user click on this button and the server is not achievable, i will recive some undesiderable errors. Also if I want to generalize my script i do not know the value of "mylocation" previously. The page contains elements to submit the Form also: <input type="submit" name="SUBMIT" value="MyValue" onClick="return eval('validationForm()')" /> For the submitting I'm using the ajaxForm plugin and it works quite well. This is a snippet of code: Thanks to your answer I found the solution to the problem. That's the code: function checkConnection(u,s){ $.ajax({ url:u, cache:false, timeout:3000, error: function(jqXHR, textStatus) { alert("Request failed: " + textStatus ); }, success: function() { eval(s); } }); } $(document).ready(function() { // part of the function that checks buttons with redirect // for any input that contain a redirect on onClick attribute ("window.locarion=") $("input[type=button]").each(function(){ var script = $(this).attr("onClick"); var url = ""; var position = script.indexOf("window.location") ; if (position >= 0) { // case of redirect url = script.substring(position+17, script.lenght); url = url.split("\'")[0]; url = "\'"+url+"\'"; // that's my url script = "\""+script+"\""; // that's the complete script $(this).attr("onClick","checkConnection("+url+","+script+")"); } }); // part of the function that checks the submit buttons (using ajaxForm plugin) var is_error = false; var options = { error: function() { if (alert("Error Message")==true) { } is_error = true; }, target: window.document, replaceTarget: is_error, timeout: 3000 }; $("#myForm").ajaxForm(options); }); I hope that this will be usefull.

  • Calling a webservice synchronously from a Silverlight 3 application?

    - by Lasse V. Karlsen
    I am trying to reuse some .NET code that performs some calls to a data-access-layer type service. I have managed to package up both the input to the method and the output from the method, but unfortunately the service is called from inside code that I really don't want to rewrite in order to be asynchronous. Unfortunately, the webservice code generated in Silverlight only produces asynchronous methods, so I was wondering if anyone had working code that managed to work around this? I tried the recipe found here: The Easy Way To Synchronously Call WCF Services In Silverlight, but unfortunately it times out and never completes the call. Or rather, what seems to happen is that the completed event handler is called, but only after the method returns. I am suspecting that the event handler is called from a dispatcher or similar, and since I'm blocking the main thread here, it never completes until the code is actually back into the GUI loop. Or something like that. Here's my own version that I wrote before I found the above recipe, but it suffers from the same problem: public static object ExecuteRequestOnServer(Type dalInterfaceType, string methodName, object[] arguments) { string securityToken = "DUMMYTOKEN"; string input = "DUMMYINPUT"; object result = null; Exception resultException = null; object evtLock = new object(); var evt = new System.Threading.ManualResetEvent(false); try { var client = new MinGatServices.DataAccessLayerServiceSoapClient(); client.ExecuteRequestCompleted += (s, e) => { resultException = e.Error; result = e.Result; lock (evtLock) { if (evt != null) evt.Set(); } }; client.ExecuteRequestAsync(securityToken, input); try { var didComplete = evt.WaitOne(10000); if (!didComplete) throw new TimeoutException("A data access layer web service request timed out (" + dalInterfaceType.Name + "." + methodName + ")"); } finally { client.CloseAsync(); } } finally { lock (evtLock) { evt.Close(); evt = null; } } if (resultException != null) throw resultException; else return result; } Basically, both recipes does this: Set up a ManualResetEvent Hook into the Completed event The event handler grabs the result from the service call, and signals the event The main thread now starts the web service call asynchronously It then waits for the event to become signalled However, the event handler is not called until the method above has returned, hence my code that checks for evt != null and such, to avoid TargetInvocationException from killing my program after the method has timed out. Does anyone know: ... if it is possible at all in Silverlight 3 ... what I have done wrong above?

  • Jquery accordion, next and previous wizard, how to get previous and next sections?

    - by Wbdvlpr
    Hi I have a Jquery accordion which works fine. Sections get expanded/collapsed when clicked on respective headers. But I want to add the functionality so that when I click on "next" button it opens up the next section and clicking "Previous" button takes me back to previous section. This has been done on this page http://jquery.bassistance.de/accordion/demo/?p=1.1.2 (last example) but not sure how do I implement the same in my case. Any suggestions please. Thanks UPDATE: How do I get previous or next section of the accordion? <script type="text/javascript"> $("#accordion").accordion({ header: "h3.header" , autoHeight: false , collapsible: true }); </script> <div id="accordion"> <h3 class="header">Section 1</h3> <div> content 1 .. content 1 .. content 1 .. content 1 .. <input class="next" type="button" value="next"/> </div> <h3 class="header">Section 2</h3> <div> content 2 .. content 2 .. content 2 .. content 2 .. <input class="previous" type="button" value="previous"/> <input class="next" type="button" value="next"/> </div> <h3 class="header">Section 3</h3> <div> content 3 .. content 3 .. content 3 .. content 3 .. <input class="previous" type="button" value="previous"/> </div> </div>
