Query is: string updateQuery = "UPDATE [TABLE] SET [COLUMN] = " + Convert.ToInt32(chk.Checked) + " WHERE PK_ID =" + dataKey + " ";` also i want some help in displaying the result as it is inside the table.means if the value for column in table for a particular pkid is 1 then the checkbox shoul be checked. Here is the code snippet: <asp:ListView ID="lvFocusArea" runat="server" DataKeyNames="PK_ID" OnItemDataBound="lvFocusArea_ItemDataBound"> <LayoutTemplate> <table border="0" cellpadding="1" width="400px"> <tr style="background-color: #E5E5FE"> <th align="left"> Focus Area </th> <th> Is Current Focused </th> </tr> <tr id="itemPlaceholder" runat="server"> </tr> </table> </LayoutTemplate> <ItemTemplate> <tr> <td width="80%"> <asp:Label ID="lblFocusArea" runat="server" Text=""><%#Eval("FOCUS_AREA_NAME") %></asp:Label> </td> <td align="center" width="20%"> <asp:CheckBox ID="chkFocusArea" runat="server" OnCheckedChanged="chkFocusArea_CheckedChanged" AutoPostBack="true" /> </td> </tr> </ItemTemplate> <AlternatingItemTemplate> <tr style="background-color: #EFEFEF"> <td> <asp:Label ID="lblFocusArea" runat="server" Text=""><%#Eval("FOCUS_AREA_NAME") %></asp:Label> </td> <td align="center"> <asp:CheckBox ID="chkFocusArea" runat="server" OnCheckedChanged="chkFocusArea_CheckedChanged" AutoPostBack="true" /> </td> </tr> </AlternatingItemTemplate> <SelectedItemTemplate> <td> item selected </td> </SelectedItemTemplate> </asp:ListView> Help me.

  • Using selection sort in java to sort floats

    - by user334046
    Hey, I need to sort an array list of class house by a float field in a certain range. This is my code for the selection sort: public ArrayList<House> sortPrice(ArrayList<House> x,float y, float z){ ArrayList<House> xcopy = new ArrayList<House>(); for(int i = 0; i<x.size(); i++){ if(x.get(i).myPriceIsLessThanOrEqualTo(z) && x.get(i).myPriceIsGreaterThanOrEqualTo(y)){ xcopy.add(x.get(i)); } } ArrayList<House> price= new ArrayList<House>(); while(xcopy.size()>0){ House min = xcopy.get(0); for(int i = 1; i < xcopy.size();i++){ House current = xcopy.get(i); if (current.myPriceIsGreaterThanOrEqualTo(min.getPrice())){ min = current; } } price.add(min); xcopy.remove(min); } return price; } Here is what the house class looks like: public class House { private int numBedRs; private int sqft; private float numBathRs; private float price; private static int idNumOfMostRecentHouse = 0; private int id; public House(int bed,int ft, float bath, float price){ sqft = ft; numBathRs = bath; numBedRs = bed; this.price = price; idNumOfMostRecentHouse++; id = idNumOfMostRecentHouse; } public boolean myPriceIsLessThanOrEqualTo(float y){ if(Math.abs(price - y)<0.000001){ return true; } return false; } public boolean myPriceIsGreaterThanOrEqualTo(float b){ if(Math.abs(b-price)>0.0000001){ return true; } return false; } When i call looking for houses in range 260000.50 to 300000 I only get houses that are at the top of the range even though I have a lower value at 270000. Can someone help?

  • VB.Net IO performance

    - by CFP
    Having read this page, I can't believe that VB.Net has such a terrible performance when it comes to I/O. Is this still true today? How does the .Net Framework 2.0 perform in terms of I/O (taht's the version I'm targeting)?

  • Python regex to parse text file, get the items in list and count the list

    - by Nemo
    I have a text file which contains some data. I m particularly interested in finding the count of the number of items in v_dims v_dims pattern in my text file looks like this : v_dims={ "Sales", "Product Family", "Sales Organization", "Region", "Sales Area", "Sales office", "Sales Division", "Sales Person", "Sales Channel", "Sales Order Type", "Sales Number", "Sales Person", "Sales Quantity", "Sales Amount" } So I m thinking of getting all the elements in v_dims and dumping them out in a Python list. Then compute the len(mylist) to get the count of the items. The challenge is in getting all the elements of v_dims from my text file and putting them in an empty list. I m particularly interested in items in v_dims in my text file. The text file has data in the form of v_dims pattern i showed in my original post. Some data has nested patterns of v_dims. Thanks. Here's what I have tried and failed. Any help is appreciated. TIA. import re fname = "C:\Users\XXXX\Test.mrk" with open(fname, "r") as fo: content_as_string = fo.read() match = re.findall(r'v_dims={\"(.+?)\"}',content_as_string) Though I have a big text file,

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

  • Unnecessary scroll bars appearing in IE8

    - by Abhishek Jain
    Hi, In my web app there is a page(ChildPage) which is actually contained in an iframe element of another page(ParentPage). This ChildPage has its contents placed in ContentPlaceHolder of a MasterPage. <div id="DivScroll" runat="server" style="overflow-y: auto; overflow-x: auto; width: 100%; height: 100%;"> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> As apparent in the code, contents of ChildPage are scrollable in the div containing it. There is never the need for the scroll bars of browser to appear and it is working this way till IE7. In IE8 browser scrollbras are appearing due to the presence of the following div in ChildPage. <div class="ReadOnlyFlat" id="Div1" style="z-index: 100; visibility: hidden; overflow: auto; width: 100%; position: absolute; height: 300px" runat="server" ms_positioning="FlowLayout"> <radA:RadAjaxPanel ID="RadAjaxPanelA" EnableOutsideScripts="True" runat="server"> <radT:RadTreeView ID="RadTreeView2" TabIndex="1" runat="server" Skin="web20"> <NodeTemplate> <asp:Label ID="Label2" runat="server">Label</asp:Label> <asp:Label ID="Label4" runat="server" Width="10px"></asp:Label> <asp:Label ID="Label3" runat="server" ForeColor="#FF8000" Font-Bold="True">Label</asp:Label> </NodeTemplate> </radT:RadTreeView> </radA:RadAjaxPanel> What actually happens in IE8 is as follows: The above div Div1 is diaplyed on the click of an ImageButton. On the page load this ImageButton is present on the bottom of the page. In this case IE8 shows browser's vertical scrollbar due to height of Div1. When I scroll DivScroll shown in first code snippet, the ImageButton moves up. When the ImageButton is moved sufficiently up so that it is above the bottommost part of page by more than 300px(i.e, the height of Div1) and if I click the ImageButton, the browser's vertical scrollbars disappear. Browser's vertical scrollbar appears in case the distance between ImageButton and the bottom most part of page is less than height of Div1 and disappears when the distance is more than height of Div1. I need that the browser's vertical scrollbar never appears. Please Help.

If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error. So the pager does not work correctly. I think it's because of the Image's Id that has to be generated dinamically but i don't know how to do it. Can someone help me?

  • Issues passing values to shader

  • Trying to read FormsAuthentication tickets to read in other areas of site

    - by Pasha Aryana
    Hi, NOTE: I have included 3 links in here to my localhost areas but could not submit the post so I seperetaed them with a space character so it would post on stackoverflow. I currently have 2 ASP.NET MVC apps in my solution. First I run the first one by setting it to be startup project. It goes to the login page, from there once the data has been entered I execute the following code: var authTicket = new FormsAuthenticationTicket(1, login.LoginDataContract.MSISDN, DateTime.Now, DateTime.Now.AddMinutes(Convert.ToDouble("30")), true, ""); string cookieContents = FormsAuthentication.Encrypt(authTicket); var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, cookieContents) { Expires = authTicket.Expiration, //Path = FormsAuthentication.FormsCookiePath //Path = "http://localhost" Domain = "" }; if (System.Web.HttpContext.Current != null) { System.Web.HttpContext.Current.Response.Cookies.Add(cookie); } As you can see I have set the Domain = "", so theoretically speaking it should work on any thing under my http: //localhost. Then I have set the persist security of the cookie to true so I can access it from any where under localhost. The cookie writes fine and I get logged in and all godd for now. BTW the url for this login page is: http //localhost/MyAccount/Login Now then I stop the solution and set the other MVC apps to be the startup. Then I run it. The URL for the second site is: http: //localhost/WebActivations/ Here is the code in the other apps start controller: public class HomeController : Controller { public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; // PASHA: Added code to read the authorization cookie set at // login in MyAccount *.sln for (int i = 0; i < System.Web.HttpContext.Current.Request.Cookies.Count;i++) { Response.Write(System.Web.HttpContext.Current.Request.Cookies[i].Name + " " + System.Web.HttpContext.Current.Request.Cookies[i].Value); } HttpCookie authorizationCookie = System.Web.HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName.ToString()]; // decrypt. FormsAuthenticationTicket authorizationForm = FormsAuthentication.Decrypt(authorizationCookie.Value); ViewData["Message"] = authorizationForm.UserData[0].ToString(); return View(); } public ActionResult About() { return View(); } The problem is in this Home controller when I run the solution it cannot read the authentication cookie, you see the loop there it does not find the .ASPXAUTH cookie. But once it crashes in Firefox I have a look in the Page Info and then security and Cookies and its there and its the same cookie. What am I doing wrong?

  • How to check if a checkbox in a checkbox array is checked with jquery

    - by eddy
    Hello everyone. I have a html table with a column of text boxes (mileage), all of them are disabled when the page loads, and I need that when user clicks on a check box, the text box for that column should be enabled and become a required field, and then if the user unchecks the checkbox, the textbox on that row must be disabled and the required class removed. I already have the function to enable and disable the text boxes (column mileage) when the user clicks on the corresponding checkbox, but it is written in javascript.However, for some reason it only works in IE). Here is the html code <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectItems" value="<c:out value="${item.numberPlate}"/>" onchange="enableTextField(this)" /> </td> <td align="left"><c:out value="${item.numberPlate}"/></td> <td align="left"><c:out value="${item.driver.fullName}"/></td> <td align="left"><input type="text" name="mileage_<c:out value="${item.numberPlate}"/>" value="" disabled="true"/></td> </tr> </c:forEach> </tbody> And the javascript code: function enableTextField(r) { var node = r.parentNode; while( node && node.tagName !== 'TR' ) { node = node.parentNode; } var i=node.rowIndex; if(document.form1.selectItems[i-1].checked) { document.getElementById('mileage_' + document.form1.selectItems[i-1].value).disabled=false; } else { document.getElementById('mileage_' + document.form1.selectItems[i-1].value).value=""; document.getElementById('mileage_' + document.form1.selectItems[i-1].value).disabled=true; } } Now, I know that in order to add or remove dynamically validation rules I have to use: addClass('required'); o removeClass('required') ,but I don't know how to detect whether a check box is selected or not, and based on that ,enable or disable the text box for that row. I really hope you can help me out with this.

  • Django filter vs exclude

    - by Enrico
    Is there a difference between filter and exclude in django? If I have self.get_query_set().filter(modelField=x) and I want to add another criteria, is there a meaningful difference between to following two lines of code? self.get_query_set().filter(user__isnull=False, modelField=x) self.get_query_set().filter(modelField=x).exclude(user__isnull=True) is one considered better practice or are they the same in both function and performance?

  • Clarification on recaptcha

    - by luckytaxi
    Um so I was in for a little bit of a surprise tonight. I spent a good 20 mins trying to figure out why I was able to submit a form knowing that what I entered into the recaptcha field was invalid. Is it true that you don't need to input the exact words it displays? If it shows me two words and I misspelled one of the words, I still pass validation? Same goes if "hello world" and I input "hell man" it still works.

  • Reproduce PIPE functionality in IronPython

    - by Muppet Geoff
    Hi, I am hoping some genious out there can help me out with this... I am using sox to merge and resample a group of WAV files, and pipe the output directly to the input of NeroAACEnc for encoding to AAC format. I originally ran the process in a script, which included: sox.exe d:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav - | neroAacEnc.exe -q 0.5 -if - -of test.m4a This worked as expected. The '-' in the comand line translates as 'Pipe/redirect input/output (stdin/stdout)' - So Sox pipes to stdout, and NeroAACEnc reads from stdin, the | joins them together. I then migrated the whole solution to Python, and the equivalent command became: from subprocess import call, Popen, PIPE runwav = Popen(['sox.exe', 'd:\audio\1.wav', 'd:\audio\2.wav', 'd:\audio\3.wav', '-c', '1', '-r', '22050', '-t', 'wav', '-'], shell=False, stdout=PIPE) runm4b = call(['neroAacEnc.exe', '-q', '0.5', '-if', '-', '-of', 'test.m4a'], shell=False, stdin=runwav.stdout) This also worked like a charm, exactly as expected. Slightly more convoluted, but hey :) Well now I have to move it to IronPython, and the Subprocess module isn't available (the partial implementation that is, doesn't have Popen/PIPE support - plus it seems silly to add a custom library when there is probably a native alternative). I should mention here, that I opted for IronPython over C#, because I am comfortable with Python now - however, there is a chance of moving it again later to C# native, and I am using IronPython to ease myself into it :) I have no C# or .net experience. So far I have the following equivalent, that sets up the 2 processes: from System.Diagnostics import Process wav = Process() wav.StartInfo.UseShellExecute = False wav.StartInfo.RedirectStandardOutput = True wav.StartInfo.FileName = 'sox.exe' wav.StartInfo.Arguments = 'd:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav -' wav.Start() m4b = Process() m4b.StartInfo.UseShellExecute = False m4b.StartInfo.RedirectStandardInput = True m4b.StartInfo.FileName = 'neroAacEnc.exe' m4b.StartInfo.Arguments = '-q 0.5 -if - -of test.m4a' m4b.Start() I know that these 2 processes start (I can see Nero and Sox in the task manager) but what I can't figure out (for the life of me) is how to string the two output/input streams together, as with the previous two solutions. I have searched and searched, so I thought I'd ask! If anyone knows either: How to join the two streams with the same net result as the Python and Commandline versions; or A better way to acheive what I am trying to do. I would be extremely grateful! Many thanks in advance, Geoff P.S. A code sample based off the above would be awesome :) or a specific code example of a similar process that I can easily translate... this has broked my brayne.

  • [obj-c] autorelease problem

    - by BQuadra
    Why the NSArray allocated with arrayWithObjects dealloc automatically if already used by BObject object?? in teory NSArray must remain allocated all the BObject life time... [[BObject alloc] initObjectName:@"oneObject" states: [NSArray arrayWithObjects: [[State alloc] initStateName:@"stand_front" singleImg:[NSArray arrayWithObjects:[UIImage imageNamed:@"front_1.png"], nil]], [[State alloc] initStateName:@"front_walking" frames: [NSArray arrayWithObjects: [UIImage imageNamed:@"front_1.png"], [UIImage imageNamed:@"front_2.png"], [UIImage imageNamed:@"front_3.png"], [UIImage imageNamed:@"front_4.png"], [UIImage imageNamed:@"front_5.png"], [UIImage imageNamed:@"front_6.png"], [UIImage imageNamed:@"front_7.png"], [UIImage imageNamed:@"front_8.png"], nil] duration:0.8 repeat:0], nil] isSolid:TRUE];
