  • Drop duplicated axis label in Flex Chart

    - by Sean Chen
    Hi, All. I use LineChart in Flex with horizontal category axis and I need drop duplicated category label on the chart. The data I use are like that: {Product: "C1", Store: "S1", Profit: "1500}, {Product: "C2", Store: "S1", Profit: "1000}, {Product: "C3", Store: "S2", Profit: "800}, {Product: "C4", Store: "S2", Profit: "1200}, {Product: "C5", Store: "S3", Profit: "1800} Beacuse I set horizontalAxis.categoryField = "Store" , the chart show label "S1,S1,S2,S2,S3" on ths axes. However, both C1 and C2 data point group on the second "S1" category (as same as C3,C4 on second S2). If I accept group data point on the same x-poistion, is there any idea to drop duplicated label?

  • C++ serial port send command

    - by Ilyssis
    Hi there, I have a hardware here, wich communicates over serial port. I use MS Visual C++ 2010, and I want to send a command: <-S-> I am doing this: SerialPort^ serialPort = gcnew SerialPort(portName , 9600, Parity::None, 8, StopBits::One); serialPort->Open(); serialPort->WriteLine("<-S->"); serialPort->Close(); But the command that goes out is <-S->., and not <-S-> (please notice the point that is attached to the outgoing command). I use Free Serial Port Monitor to watch my ingoing/outcoming data. So how can I get rid of that point in <-S->. ? This is what is going out: 3C 2D 53 2D 3E 0A = <-S-. This is what I want: 3C 2D 53 2D 3E = <-S- Thanks for help.

  • EXCEL - Locking a Cell from User input whilst allowing a Linked combobox?

    - by Christopher Leach
    I have a Protected Worksheet which is a checklist with a series of checkpoints. Each row has Item and Description cells that are locked. Each row has several columns with its contents to be set by a ComboBox and a text input column. Both i have left unlocked. I have Locked the the Item and Description columns and left only the 'Select Unlocked Cells' checked via Sheet Protection. I have one ComboBox on the worksheet that moves around and adjusts its LinkedCell and its Content list using the worksheets SelectionChanged event. When the user selects a cell to bring up the drop down list, the user is able to type into the cell and the Drop Down Box disappears. What is the best way to keep the cell unlocked so it can be selectable(as 'Select Locked Cells" is unchecked) however stop the user from being able to type in the cell and to allow the cells contents to become modifiable only via the ComboBox?

  • YAHOO.util.Connect.asyncRequest does not work in Safari

    - by 24x7Programmer
    When I request a webpage using YAHOO.util.Connect.asyncRequest in Safari I always get Communication Failure message in callback's failure properties statusText. The same method works in IE. What could be wrong here? Here is the code. When the code is executed I always get two alerts: "Three" and "communications failure undefined" (corresponding to the second alert in the failure part below.) Also when I attach the debugger and put break point in the SAProvision.aspx's page load event, the break point is not hit. So it is sure that in safari the page is not being called. While the same is called when executed from IE. function ProvisionBlade() { var path = "http://localhost/SC/Dashboard/SAProvision.aspx" YAHOO.util.Connect.asyncRequest("POST", path, callbacks1, null); } var callbacks1 = { success: function(o) { var check = "test"; alert(o.responseText); }, failure: function(o) { alert("Three"); alert(o.statusText + ' ' + o.responseText); } }

  • How to enable indexing of pages with dynamic data?

    - by mithunb
    I have a site that has certain urls that point to pages with permanent data and others that point to dynamic web pages. Google indexes both these regularly. By the time a user finds one of the dynamic content urls, the data on the page has already changed and the user does not find what he was looking for. Further, the dynamic url pages contains links to the permanent urls (which I want Google or any crawler to index). Google crawler controls (webmaster tools) cannot be made to read urls from a page but not index them. Solutions? crawling strategies *system architecture*.

  • Unread email notifier, most practical approach

    - by Michael Pasqualone
    I'm in the process of writing a small php-cli script that will loop over over my personal inbox and then send me an SMS via a gateway. The question I have is: As will have the script launch via cron every 10 minutes, if there is an email sitting in my inbox that is not read before the next script launch then I will receive 2 sms. Does any one (pseudocode will do) have any idea what the best practice would be in php5 to ensure only 1 SMS is sent? What I am currently learning towards is towards storing the message ID in a sqlite DB and flagging a field whether an SMS has been sent or not - but wondering if there is an easier way?

  • Objective-c pointer assignment and reassignment dilema

    - by moshe
    Hi, If I do this: 1 NSMutableArray *near = [[NSMutableArray alloc] init]; 2 NSMutableArray *all = [[NSMutableArray alloc] init]; 3 NSMutableArray *current = near; 4 current = all; What happens to near? At line 3, am I setting current to point to the same address as near so that I now have two variables pointing to the same place in memory, or am I setting current to point to the location of near in memory such that I now have this structure: current - near - NSMutableArray The obvious difference would be the value of near at line 4. If the former is happening, near is untouched and still points to its initial place in memory. If the latter is happening,

  • How to Generate Embeddable Widgets, and Return PartialView, JS & CSS as JSONP?

    - by DaveDev
    I found this question which is a great starting point towards creating embedded widgets that enable showing dynamic content on remote sites (i.e. a different domain). One problem I'm having is with the following code: public ActionResult SomeAction() { return new JsonpResult { Data = new { Widget = "some partial html for the widget" } }; } It says Widget = "some partial html for the widget" but this doesn't really mean anything to me. I assume that Widget would contain the HTML representing what the user wants to see on the screen, but How do I get the contents of my Partial View into Widget? Can anyone point me in the right direction? Thanks..

  • Authenticating a user for a single app with multiple domains

    - by hofnarwillie
    I have one asp.net web application, but two different domains point to this web app. For instance: www.one.com and www.two.com both point to the same web app. I have an issue where I need certain pages to be on a specific domain (due to some security requirements from our online payment provider - a third party website). So let's say page1.aspx needs to be called on www.two.com The process is as follows: A user logs into www.one.com The authentication cookie is saved to the browser The user then navigates to page1.aspx and, if on the wrong domain, gets redirected to the correct domain. (this redirection happens on page1.aspx in the page_load event) Then asp.net redirects the user to the login screen, because the authentication cookie is not sent to www.two.com. How can I track the user and keep him/her logged in between the two domains?

  • How can I programmatically copy all of the style attributes from one DOM element to another

    - by stu
    I have a page with two frames, and I need to (via javascript) copy an element and all of its nested elements (it's a ul/li tree) and most importantly it's style from one frame to the other. I get all the content via assigning innerhtml, and I am able to position the new element in the second frame with dest.style.left and dest.style.top and it works. But I'm trying to get all the style information and nothing's happening. I'm using getComputedStyle to get the final style for each source element as I loop through each node then and assigning them to the same position in the destination nodelist and nothing happens to visually change the style. What am I missing?

  • Two parallel line segments intersection

    - by Judarkness
    I know there are many algorithms to verify whether two line segments are intersected. But once they encountered parallel condition, they just tell the user a big "No" and pretend there is no overlap, share end point, or end point collusion. I know I can can calculate the distance between 2 lines segments. If the distance is 0, check the end points located in the other line segments or not. And this means I have to use a lot of if else and && || conditions. This is not difficult, but my question is "Is there a trick( or mathematics) method to calculate this special parallel case?"

  • Is there a way to set up a Linux pipe to non-buffering or line-buffering?

    - by ern0
    My program is controlling an external application on Linux, passing in input commands via a pipe to the external applications stdin, and reading output result via a pipe from the external applications stdout. The problem is that writes to pipes are buffered by block, and not by line, and therefore delays occur before my app receives data output by the external application. The external application cannot be altered to add explicit fflush() calls. When I set the external application to /bin/cat -n (it echoes back the input, with line numbers added), it works correctly, it seems, cat flushes after each line. The only way to force the external application to flush, is sending exit command to it; as it receives the command, it flushes, and all the answers appears on the stdout, just before exiting. I'm pretty sure, that Unix pipes are appropiate solution for that kind of interprocess communication (pseudo server-client), but maybe I'm wrong. (I've just copied some text from a similar question: Force another program's standard output to be unbuffered using Python)

  • Strange WPF Behaviour With WCF Async calls

    - by gvigsgb
    I have a WPF application calling WCF via Async calls. The application has four tabs in which each are loaded from seperate async calls, each tab has a busy indicator. The problem: When running within Visual Studio I can click a refresh button on each tab and each tab's busy indicator starts and the data is retrieved from the WCF service. As each tab's data comes back it is refreshed. When I deploy the application via one click the application's UI hangs after only two tabs start refreshing. So in this case I press refresh on tab one, then on tab two and the application hangs until one of the two tabs data comes back. I thought at first that it was something to do with the WCF service throtteling and that was not the case as both the Visual Studio and the One Click deployments of the application point to the same service. Anyone have any ideas on where to look? I cannot reproduce the hang issue within Visual Studio?

  • VC++ how to change a picturebox from header file

    - by JimboJones
    HI, Just ran into a problem. How to I change a picturebox's picture from within a different header file. If I do it in the same .h file as the Form I am working on I use: sq1-Image = bi; (which loads in a bitmap) but when I do it from another header (i've included the correct header file), I get "sq1 is an undeclared identifier" and "left of '-image' must point to a class/struct/union/generic" What I'm looking for is something like Form1::sq1-Image = bi; Basically I just want to point the program to change picturebox from another location....Is this possible? How can I do this? Cheers!

  • Is Classic ADO still viable for a mixed managed/unmanaged App?

    - by Andy Dent
    We have a complex architecture with much logic in unmanaged code that needs database access. Currently this is via ODBC drivers and MFC classes and we're considering the issues of migrating our abstraction layer to use ADO or ADO.Net. In the latter case we'd have to be pushing database logic back up into the .Net layer. I'm trying to decide if the pain of invoking the database via .Net callbacks is offset by the improvements in ADO.Net. The Wikipedia comparison was interesting although I'm not sure I believe all the points in the comparison table (eg: does ADO.Net always use XML to pass data?). A 2005 comparison shows ADO.Net performing dramatically faster. Microsoft's guide to ADO.Net for ADO programmers suggests we will gain much from going to ADO.Net especially the way that data is available in native (.Net) types rather than solely through OLEAutomation's Variant.

  • Any way to chunk gzip with Apache and PHP

    - by donatJ
    I have a web application on a site that takes a while (~10 seconds) to complete a portion of the page near the bottom - it has been as optimized as it can be, and caching is not an option. We have compression enabled on the server via an .htaccess directive SetOutputFilter DEFLATE the problem is this causes the whole page to be held until completion before it starts outputting to the user, this is not optimal as the user sees nothing until the page completes. I have also tried it via the php ob_start("ob_gzhandler"); method. Currently I have a <FilesMatch > in my .htaccess restricting this specific script from being compressed. Basically my question is this - Is there a way to say chunk gzip or deflate so that the user gets it in pieces, so they can see that the page has begun loading?

  • How do I remove descendant elements from a jQuery wrapped set?

    - by Bungle
    I'm a little confused about which jQuery method and/or selectors to use when trying to select an element, and then remove certain descendant elements from the wrapped set. For example, given the following HTML: <div id="article"> <div id="inset"> <ul> <li>This is bullet point #1.</li> <li>This is bullet point #2.</li> <li>This is bullet point #3.</li> </ul> </div> <p>This is the first paragraph of the article</p> <p>This is the second paragraph of the article</p> <p>This is the third paragraph of the article</p> </div> I want to select the article: var $article = $('#article'); but then remove <div id="inset"></div> and its descendants from the wrapped set. I tried the following: var $article = $('#article').not('#inset'); but that didn't work, and in retrospect, I think I can see why. I also tried using remove() unsuccessfully. What would be the correct way to do this? Ultimately, I need to set this up in such a way that I can define a configuration array, such as: var selectors = [ { select: '#article', exclude: ['#inset'] } ]; where select defines a single element that contains text content, and exclude is an optional array that defines one or more selectors to disregard text content from. Given the final wrapped set with the excluded elements removed, I would like to be able to call jQuery's text() method to end up with the following text: This is the first paragraph of the article.This is the second paragraph of the article.This is the third paragraph of the article. The configuration array doesn't need to work exactly like that, but it should provide roughly equivalent configuration potential. Thanks for any help you can provide!

  • Separate web and email host

    - by user871993
    My client has their domain name (lorem.com) registered with company X which also host their email. I'd like to host their new website with separate hosting company (company Y). I know I need to update the DNS nameservers for their domain name to point to company Y's nameservers. I'm not sure how to handle the email host though. Doing an MX lookup on their domain, currently shows: Pref Hostname 10 lorem.com 20 mx2.companyX.com Do I need to do any updates to the MX record? Also, do I need to add/edit the A record to point to company Y's IP address? Thanks!

  • php $_POST array empty upon form submission...

    - by Mike D
    Hi folks, I'm baffled on this after much googling. This issue is simple, I have a custom CMS i've built that works perfectly on my dev box (Ubuntu/PHP5+/MySQL5+). I just moved it up to the production box for my client and now all form submissions are showing up as empty $_POST arrays. I found a trick to verify the data is actually being passed using "file_get_contents('php://input');" and the data is showing up fine there -- the $_POST/$_REQUEST arrays are always empty. I've also verified the content-type headers are correct as well via firebug (application/x-www-form-urlencoded; charset=utf-8). This issue is happening regardless of whether a form is submitting via AJAX or a regular form submit. Any help is greatly appreciated!
