  • CSS Hidden DIV Form Submit

    - by Michael
    Using CSS, when a link is clicked it brings up a hidden DIV that contains a form. The user will then enter information and then submit the form. I'd like the hidden DIV to remain visisble, and a 'success message' to be displayed after submission. Then the user will have the option of closing the DIV. I can't get it to work without reloading the page, which causes the DIV to become hidden again. Any ideas? <body> <a href="javascript:showDiv()" style="color: #fff;">Click Me</a> <!--POPUP--> <div id="hideshow" style="visibility:hidden;"> <div id="fade"></div> <div class="popup_block"> <div class="popup"> <a href="javascript:hideDiv()"> <img src="images/icon_close.png" class="cntrl" title="Close" /> </a> <h3>Remove Camper</h3> <form method="post" onsubmit="email.php"> <p><input name="Name" type="text" /></p> <p><input name="Submit" type="submit" value="submit" /></p> </form> <div id="status" style="display:none;">success</div> </div> </div> </div> <!--END POPUP--> <script language=javascript type='text/javascript'> function hideDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'hidden'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'hidden'; } else { // IE 4 document.all.hideshow.style.visibility = 'hidden'; } } } function showDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'visible'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'visible'; } else { // IE 4 document.all.hideshow.style.visibility = 'visible'; } } } </script> </body>

  • .NET 3.5 C# does not offer what I need for locking: Count async saves until 0 again.

    - by Frank Michael Kraft
    I have some records, that I want to save to database asynchronously. I organize them into batches, then send them. As time passes, the batches are processed. In the meanwhile the user can work on. There are some critical operations, that I want to lock him out from, while any save batch is still running asynchronously. The save is done using a TableServiceContext and method .BeginSave() - but I think this should be irrelevant. What I want to do is whenever an async save is started, increase a lock count, and when it completes, decrease the lock count so that it will be zero as soon as all have finished. I want to lock out the critical operation as long as the count is not zero. Furthermore I want to qualify the lock - by business object - for example. I did not find a .NET 3.5 c# locking method, that does fulfil this requirement. A semaphore does not contain a method to check, if the count is 0. Otherwise a semaphore with unlimited max count would do.

  • What's a good way to encrypt data using an asymmetric key, that's available to both java and ruby?

    - by Michael Campbell
    I have a customer that wants to encrypt some data in his database (not passwords; this needs actual encryption, not hashing). The application which will be doing the encrypting/writing is in Java, but the process which will DECRYPT it is behind a secure firewall, and is written in ruby. The idea was to use a public/private key scheme; the java system would encrypt it with the public key, then the process on his local box would use the private key to decrypt it as needed. I'm looking for any experience anyone has doing something like that; my main question is what sorts of libraries on java and ruby can interoperate with the same keys and data.

  • Detecting if MSBuild/.net 4 is installed from C# code running on 3.5?

    - by Michael Stum
    I have an application that is running on .net 3.5 SP1 and that is supposed to check if .net 4 is installed. Actually, I'm more interested if MSBuild v4 is installed, which would boil down to a simple File.Exists(@"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe"); However, apart from the fragility of the 4.0.30319 Version (and the Windir, but that's easy to solve), I wonder if there is a more appropriate way, like an API?

  • Objective-C retain counts in dealloc

    - by Michael Waterfall
    I'm seeing something fairly strange here, I've got breakpoints set in various dealloc methods in my app, and on inspection, the retain counts of the object self varies from 1 to 0. When dealloc is called, will the retain count of the object be set to 0 already? I'm using print (int) [self retainCount] in the console to test this. The 0's seem to only appear in the dealloc of my NSOperation's that are being run in an NSOperationQueue. Any idea why this is?

  • Problem with absolute positioning div over SWF and IE 8.

    - by Michael S. Kelly
    I'm attempting to use the old IFrame-over-SWF trick to get HTML to display "inside" a SWF. I'm following the example provided by Brian Deitte at: http://www.deitte.com/IFrameDemo3/IFrameDemo.html. (The source code can be viewed and downloaded by right-clicking on the SWF and selecting "View Source".) In the latest versions of Firefox, Google, Opera, and Safari on the Mac, it all looks good. But in IE 8 the absolutely positioned div containing the IFrame is positioned too far up and left, and the height and width are considerably smaller. Thoughts?

  • Why do some people prefer "T const&" over "const T&"?

    - by Michael Aaron Safyan
    So, I realize that const T& and T const& are identical and both mean a reference to a const T. In both cases, the reference is also constant (references cannot be reassigned, unlike pointers). I've observed, in my somewhat limited experience, that most C++ programmers use const T&, but I have come across a few people who use T const&. Is this just a personal preference? Why is one chosen over the other?

  • Question about Modal Dialog in Gtk application

    - by michael
    Hi, In Gtk application, there is 1 main loop which listens for events (e.g. mouse click, keyboard, etc). And when a modal dialog popup, the main loop is blocked until user clicks 'OK' in the dialog, right? (i.e. nothing will happen when user clicks on the main window). Is that correct? My question is how can firefox did its modal dialog so that it can: 1. when 1 have 2 Firefox windows 2. one of them has a modal dialog 3. other one is still interactive If both window shares the same gtk main loop, how is that possible? Please help me understanding this. Thank you.

  • What encoding to use for exporting to CSV?

    - by Michael Borgwardt
    I'm developing a java app that exports data to CSV files, intended to be opened in Excel by end users. We just noticed that the export function uses Java's platform default encoding. This causes umlaut characters to be lost and unit test to fail on the build server (which is configured to have US-ASCII as its platform default encoding exactly to catch such potential problems). The question is: which would be the best encoding to use? How does Excel determine what encoding to use? Does it use something platform-specific that presumably matches Java's platform default? I'm currently leaning towards hardcoding Cp1252 - that should cover the target machines (the deployment environment is actually specified) and would fix the test problem. From googling around, Excel does not seem to handle UTF-8 well, so that's out, and sticking to the platform default encoding would require some sort of workaround hack for the tests.

  • Can I get Androis OS?

    - by Michael Turner
    I bought a umpc on ebay, A Ipad touchscreen like device. I had been looking at a particular hardware model that many sellers had, on which was running Android (1.6). I based my choice on the one that offered "free" shipping via UPS (3-5 day) delivery. after the purchase I noticed that the one I bought has Windows CE, not android (!#$^%!!!). Now I want to know if I can get a copy of Android 1.6 or higher and put it on this device. I have looked on google, Torrent sites and ebay, but cannot find a copy of Android OS

  • Should uni provide "correct answer" after programming assignment is due?

    - by Michael Mao
    Hi all: This is my very first subjective question. And I think it is programming related - the assignment is to be written in a programming language. I am not for "getting the full marks out of a subject". I am actually not for a "correct answer", but for a "better solution", so that I can compare, and can improve. I reckon it is good that I practice programming first and check the solution later to pick up the things I've done wrong/bad. Without a "benchmark" to against, this would be much harder. Unfortunately as far as I know, not all programming subjects taught in uni would kindly provide the students with a "correct answer" in the end, after the assignment is due. One bad metaphor for this is like someone asks you a question which they don't have a clear answer themselves and hope to take advantage of your answer as the basis for their answer. Personally, I feel having a assignment solution provided by the academic staff is essential to students. I do appreciate this, and I feel I might not be the only one. I am a very proactive student in uni. I learn more, I practice more, an assignment for me is more like a challenge to achieve "the best solution I can come up with", not something "I have to pass"... The cause of this question is that for the past few days I have crafted 500+ lines of Perl code, for a tiny assignment. I feel pain when I look at my solution(not finished yet) and I feel like I am an idiot doing some crap code. I know there must be a much better solution. And I reckon it is better for the lecturer in this subject to get me one, rather than asking for an answer here, even I would shamelessly add the link to my solution apart from the assignment requirements. I know in SO, there are a lot of tutors/lecturers for programming subjects/courses. I'd like to hear your words on this question.

  • Inject a EJB into a JSF converter with JEE6

    - by Michael Bavin
    Hi, I have a stateless EJB that acceses my database. I need this bean in a JSF 2 converter to retreive an entity object from the String value parameter. I'm using JEE6 with Glassfish V3 @EJB annotation does not work and gets a NPE, because it's in the faces context and it has not access to the ejb context. My question is: Is it still possible to Inject this bean (With a @Resource or other annotation, a JNDI lookup,...), or do i need a workaround? Thank you Solution Do a JNDI lookup like this: try { ic = new InitialContext(); myejb= (MyEJB) ic .lookup("java:global/xxxx/MyEJB"); } catch (NamingException e) { e.printStackTrace(); }

  • OSX Equivalent of Winsock LSP

    - by Michael
    On Windows, it's possible to program an LSP service on top of Winsock which provides the ability to do a lot of manipulation/etc. with networked applications. For instance, some anti virus applications register an LSP and analyse network traffic that way. Is there a friendly way to accomplish the same sort of thing on OSX?

  • Strange behaviour of NSScanner on simple whitespace removal

    - by Michael Waterfall
    I'm trying to replace all multiple whitespace in some text with a single space. This should be a very simple task, however for some reason it's returning a different result than expected. I've read the docs on the NSScanner and it seems like it's not working properly! NSScanner *scanner = [[NSScanner alloc] initWithString:@"This is a test of NSScanner !"]; NSMutableString *result = [[NSMutableString alloc] init]; NSString *temp; NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet]; while (![scanner isAtEnd]) { // Scan upto and stop before any whitespace [scanner scanUpToCharactersFromSet:whitespace intoString:&temp]; // Add all non whotespace characters to string [result appendString:temp]; // Scan past all whitespace and replace with a single space if ([scanner scanCharactersFromSet:whitespace intoString:NULL]) { [result appendString:@" "]; } } But for some reason the result is @"ThisisatestofNSScanner!" instead of @"This is a test of NSScanner !". If you read through the comments and what each line should achieve it seems simple enough!? scanUpToCharactersFromSet should stop the scanner just as it encounters whitespace. scanCharactersFromSet should then progress the scanner past the whitespace up to the non-whitespace characters. And then the loop continues to the end. What am I missing or not understanding?

  • jQuery i++ and i-- problems ... what on earth???

    - by michael
    Could someone please tell me what I am doing wrong? I'm not a newbie at programming but I feel like it tonight! Every time I increment the incrementing variable it throws a fit! When add one to it, it behaves fine, but if I try to add one more to it it wants to add 2 more. And then if I try to de-increment it wants to subtract from the original number that it was assigned to. I've tried: i++; i = i+1; i = i++; Nothing seems to work. It's got to be a stupid mistake. Press the buttons to increment and de-increment. http://michaelreynolds.net/iphone/ here's the code: var dayNum = 30; //---------------------------------------------------------------------- $.jQTouch({ icon: 'dailyqoteicon.png', statusBar: false, initializeTouch: 'a.touch' }); //---------------------------------------------------------------------- $(document).ready(function(){ //$(function(){}); $(function(){ $('a.touch').swipe( function(event, info){ //alert("jQTouch swipe event"); //alert(info.direction); }); }); $(function updateVerse(){ //alert("updateVerse called"); $.ajax({ type: "GET", dataType: 'JSON', data: 'day='+ dayNum, url: 'forward.php', success: function(data){ var obj = $.parseJSON(data); $("h2.quote").html(""); $("h3.reference").html(""); $("h2.quote").append(obj.quote); $("h3.reference").append(obj.reference, " ", obj.version); //$("span.version").append(obj.version); //----------------------------------- // JSON string {"id":"1","quote":"For to me, to live is Christ, and to die is gain","reference":"Philippians 1:21","version":"NKJV"} }, error: function(request, error){ alert("problem retrieving json data string"); } }); function addDayNum(){ dayNum = dayNum + 1; //dayNum = dayNum++; } function subDayNum(){ dayNum = dayNum - 1; //dayNum = dayNum--; } $("div#header a.next").tap( function(){ addDayNum(); //dayNum++;// doesn't work at all //dayNum = dayNum + 1;//doesn't work at all updateVerse(); //alert(dayNum); //alert("next clicked"); }); $("div#header a.prev").live('click', function(){ subDayNum(); //dayNum--;//doesn't work at all //dayNum = dayNum - 1;// doesn't work at all updateVerse(); //alert(dayNum); //alert("previous clicked"); }); }); });

  • Replicate Printed Form With Web Form

    - by Michael
    I'm hoping people have some ideas to help solve this problem. I am developing a C# ASP.NET website and the client requires an online form that users will fill in and submit. OK, so far so good..... Imagine, say, a form that you fill in on paper - they normally have a distinctive look specific to the company and will be filed, quite possibly as a legally binding document. I need to have an online form that when submitted emails the client with something they can print out and will look exactly like their printed forms. As this is web based, I think the option of capturing a screenshot are out the question, so I'm wondering how best to approach this? Even if I just had a form that captures the data presented how I want, how could I translate this data into the view they want? Any ideas and suggestions greatly appreciated.

  • How make decides to build target

    - by Michael
    One sign is that target does not exist, understand this. Another is by comparing modification timestamp of target and prerequisites. How it works in more details? What is the logic of comparing target and prerequisite timestamps and how it works when there are multiple prerequisites?
