  • What adapter to use for ExpandableListView with non-TextView views?

    - by David
    I have an ExpandableListView in which I'd like to have controls other than TextView. Apparently, SimpleExandableListViewAdapter assumes all the controls are TextViews. A cast exception is generated if they are not. What is the recommended solution? Options I can think of include: - Use some other included adapter. But I can't tell if they all have the same assumption. - Create my own adapter. Is there a doc which describes the contract, ie the sequence of method calls an adapter will encounter? I expected the existing adapters to require the views to conform to some interface to allow any conforming view to be used, rather than hardcode to textview and limit where they can be used.

  • WCF Multiple Services

    - by David
    Hi, im brand spanking new to WCF and Im trying to understand how to correctly expose my BLL to it. I created my first Resource.svc and IResource.svc Resource.svc [ServiceBehavior] public class Resources : IResources { #region IResources Members public List<Model.Resource> GetAll() { return Repository.Inventory.Resource.GetAll(true); } public List<Model.Resource> GetAllEnabled() { return Repository.Inventory.Resource.GetAllEnabled(true); } #endregion } IResource.cs [ServiceContract] public interface IResources { [OperationContract] List<Model.Resource> GetAll(); [OperationContract] List<Model.Resource> GetAllEnabled(); } So this all works, My windows app can talk to the service and all is great. So I now need to access some information, I have created another .svc file called Project.svc and IProject.cs, this contains the same info as resource (apart from the type is Project) But this now means I have another webservice, surley this is not right!?

  • Code-Golf: Friendly Number Abbreviator

    - by David Murdoch
    Based on this question: Is there a way to round numbers into a friendly format? THE CHALLENGE - UPDATED! (removed hundreds abbreviation from spec) The shortest code by character count that will abbreviate an integer (no decimals). Code should include the full program. Relevant range is from 0 - 9,223,372,036,854,775,807 (the upper limit for signed 64 bit integer). The number of decimal places for abbreviation will be positive. You will not need to calculate the following: 920535 abbreviated -1 place (which would be something like 0.920535M). Numbers in the tens and hundreds place (0-999) should never be abbreviated (the abbreviation for the number 57 to 1+ decimal places is 5.7dk - it is unneccessary and not friendly). Remember to round half away from zero (23.5 gets rounded to 24). Banker's rounding is verboten. Here are the relevant number abbreviations: h = hundred (102) k = thousand (103) M = million (106) G = billion (109) T = trillion (1012) P = quadrillion (1015) E = quintillion (1018) SAMPLE INPUTS/OUTPUTS (inputs can be passed as separate arguments): First argument will be the integer to abbreviate. The second is the number of decimal places. 12 1 => 12 // tens and hundreds places are never rounded 1500 2 => 1.5k 1500 0 => 2k // look, ma! I round UP at .5 0 2 => 0 1234 0 => 1k 34567 2 => 34.57k 918395 1 => 918.4k 2134124 2 => 2.13M 47475782130 2 => 47.48G 9223372036854775807 3 => 9.223E // ect... . . . Original answer from related question (javascript, does not follow spec): function abbrNum(number, decPlaces) { // 2 decimal places => 100, 3 => 1000, etc decPlaces = Math.pow(10,decPlaces); // Enumerate number abbreviations var abbrev = [ "k", "m", "b", "t" ]; // Go through the array backwards, so we do the largest first for (var i=abbrev.length-1; i>=0; i--) { // Convert array index to "1000", "1000000", etc var size = Math.pow(10,(i+1)*3); // If the number is bigger or equal do the abbreviation if(size <= number) { // Here, we multiply by decPlaces, round, and then divide by decPlaces. // This gives us nice rounding to a particular decimal place. number = Math.round(number*decPlaces/size)/decPlaces; // Add the letter for the abbreviation number += abbrev[i]; // We are done... stop break; } } return number; }

  • Improve my php image resizer to support alpha png and transparent GIFs

    - by David
    Hi, I use this function to resize images but i end up with ugly creepy image with a black background if it's a transparent GIF or PNG with alpha, however it works perfectly for jpg and normal png. function cropImage($nw, $nh, $source, $stype, $dest) { $size = getimagesize($source); $w = $size[0]; $h = $size[1]; switch($stype) { case 'gif': $simg = imagecreatefromgif($source); break; case 'jpg': $simg = imagecreatefromjpeg($source); break; case 'png': $simg = imagecreatefrompng($source); break; } $dimg = imagecreatetruecolor($nw, $nh); switch ($stype) { case "png": imagealphablending( $dimg, false ); imagesavealpha( $dimg, true ); $transparent = imagecolorallocatealpha($dimg, 255, 255, 255, 127); imagefilledrectangle($dimg, 0, 0, $nw, $nh, $transparent); break; case "gif": // integer representation of the color black (rgb: 0,0,0) $background = imagecolorallocate($simg, 0, 0, 0); // removing the black from the placeholder imagecolortransparent($simg, $background); break; } $wm = $w/$nw; $hm = $h/$nh; $h_height = $nh/2; $w_height = $nw/2; if($w> $h) { $adjusted_width = $w / $hm; $half_width = $adjusted_width / 2; $int_width = $half_width - $w_height; imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h); } elseif(($w <$h) || ($w == $h)) { $adjusted_height = $h / $wm; $half_height = $adjusted_height / 2; $int_height = $half_height - $h_height; imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h); } else { imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h); } imagejpeg($dimg,$dest,100); } I use php 5.3.2 and the GD library bundled (2.0.34 compatible) Thanks

  • ColdFusion CFC implementation of C# Partial Class?

    - by Brian David Berman
    Does ColdFusion offer a mechanism for splitting CFCs into multiple files? I am NOT talking about extension, I am talking about splitting the SAME CFC into multiple files; the same way C# allows for "partial" classes. The reason for this is because I am using T4 to generate a bunch of CFCs and I want to be able to tag functionality onto the generated CFC by doing so in another file. I want to do this in a way that doesn't violate the Open-Closed Principle.

  • Editing a Gridview row with drop-down lists gets too wide - how can I use popup panels instead?

    - by David
    I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList> </EditItemTemplate> </asp:TemplateField> The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem). What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected). I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others). All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where. I'm open to suggestions. Thanks in advance. EDIT: Final solution looks as follows: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton> <asp:Panel ID="pnlCompany" runat="server" style="display:none"> <div> <asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList> <br/> <asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" /> <asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" /> </div> </asp:Panel> <cc1:ModalPopupExtender ID="mpeCompany" runat="server" TargetControlID="lnkCompany" PopupControlID="pnlCompany" BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo" DropShadow="true" PopupDragHandleControlID="pnlCompany" /> </EditItemTemplate> </asp:TemplateField> And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView: Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Dim intRow As Integer Dim intVal As Integer RestoreFromSessionVariables() Select Case e.CommandName Case "SelectCO" intRow = grdIDCostLabor.EditIndex Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList) intVal = ddlCo.SelectedValue lstIDLabor(intRow).CompanyID = intVal lstIDLabor(intRow).Company = Company.Read(intVal) Case Else ' End Select MakeSessionVariables() BindGrids() End Sub

  • Single HTML Table from multiple MySQL tables

    - by David Chouinard
    Hi! I've been struggling for a while with this one; I'll try to explain it here as simply as possible. Consider this MySQL table: +----------+-----------+---------+--------+ |status_id |session_id |pilot_id |present | +----------+-----------+---------+--------+ |1 |61 |901 |1 | |2 |63 |901 |1 | |3 |62 |901 |0 | |4 |62 |902 |1 | |5 |63 |903 |1 | +----------+-----------+---------+--------+ Both session_id and pilot_id are foreign keys making reference to a primary key in another table. The same pilot_id can be associated with different session_id, but every pilot_id-session_id combination is unique. I need to make an HTML table (in PHP) that would display the data like this: +----------+---------+---------+---------+ | |61 |62 |63 | +----------+---------+---------+---------+ |901 |X | |X | |902 | |X | | |903 | | |X | +----------+---------+---------+---------+ Hence, rows are pilot_id and columns are session_id. When a pilot_id-session_id combination has a present value of 1, the corresponding cell should be checked. (ie. when the row-combination is zero or the combination does not exist in the MySQL table, nothing should appear in the HTML table) Phew. Any ideas? Thanks!

  • How to present the same modalView after dismissing it once

    - by David Casillas
    I'm having some problem trying to present a modal view controller after it has been presented the first time, so I just start a little test method, it presents, dismisses and presents again the same controller modally. // This is just test Code. MYViewController *vc = [[MYViewController alloc] init]; [self presentModalViewController:vc animated:YES]; [self dismissModalViewControllerAnimated:YES]; [self presentModalViewController:vc animated:YES]; I get the error: 2011-11-15 09:50:42.678 Proyecto3[1260:11603] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modally an active controller <RootViewController: 0x6d9d090>.' The documentation does not add any clue here.

  • CodeCharge : is it any good?

    - by David Burrows
    Hi, A job came in to me that's built with CodeCharge - had a look at it and seems to be a pretty basic point-and-click site builder tool. Has anyone got any in-depth experience with it? My first reaction is one of horror and to just rebuild the code in Rails or PHP but I thought I'd ask the question first, maybe i'm missing something...

  • jQuery UI - Datepicker - Hide year

    - by David
    Hi, I'm using jQuery UI 1.8 and I would like to hide the year from the user in both the popup and the textbox. Essentially instead of picking the day, month and year I want the user to just pick the day and month. Hiding the year in the textbox is easy enough, the code shown below will do that. I'm stumped on how to hide the year from the popup - so it would say "April" instead of "April 2010". $(function() { $("#beginDateRange").datepicker({ dateFormat: 'mm/dd' }); }); <input type="text" name="beginDateRange" id="beginDateRange" /> Any help would be greatly appreciated.

  • Execute Oracle RAC cluster commands via Solaris RBAC?

    - by David Citron
    Executing Oracle RAC cluster management commands such as $ORA_CRS_HOME/bin/crs_start requires root permissions. Using Solaris RBAC (Role-Based Access Control), one can give a non-root user permissions to execute those commands, but the commands still fail internally. Example: $pfexec /opt/11.1.0/crs/bin/crs_stop SomeArg CRS-0259: Owner of the resource does not belong to the group. Is there a complete RBAC solution for Oracle RAC or does the executor need to be root? EDIT: Note that my original /etc/security/exec_attr contained: MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start:uid=0 MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start.bin:uid=0 As Martin suggests below, this needed to be changed to add gid=0 as: MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start:uid=0;gid=0 MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start.bin:uid=0;gid=0

  • Is there a way to change the maximum width of a window without using the WM_GETMINMAXINFO message?

    - by David
    I want to change the imposed Windows maximum width that a window can be resized to, for an external application's window (not my C#/WinForms program's window). The documentation of GetSystemMetrics for SM_CXMAXTRACK says: "The default maximum width of a window that has a caption and sizing borders, in pixels. This metric refers to the entire desktop. The user cannot drag the window frame to a size larger than these dimensions. A window can override this value by processing the WM_GETMINMAXINFO message." Is there a way to modify this SM_CXMAXTRACK value (either system wide or for one particular window), without processing the WM_GETMINMAXINFO message? Maybe an undocumented function, a registry setting, etc.? (Or: The documentation for MINMAXINFO.ptMaxTrackSize says: "This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK." Maybe there is a way to change the size of the virtual screen?) Thank you

  • How can I force a jQuery faded-in user control to remain after click events?

    - by David
    I have a basic page to which I'm adding an uploader control based on Bulk Uploader at c-sharpcorner.com and the control is in a jQuery-faded div based on yesdegisn The Bulk Uploader has two server side event handlers for two buttons--Add and Remove. After clicking these buttons, the fade disappears and you're back to the basic page--if the user needs to add more files, this is not desirable. The ArrayList of files added to a ListBox is maintained, but I have to click the "fade-in" link (LinkButton id="lnkDocumentUpload") to display this window again. I also need the control to POST to UploadPost.aspx, and it doesn't work either. Clicking the upload button(<asp:Button ID="btnUpload" runat="server" />) has the same behavior described above--fade disappears, data is retained, and no POST. I've surrounded the control with <form id="frmUpload" action="~/UploadPost.aspx"> ... <asp:Button ID="btnUpload" runat="server" Text="Upload"/> </form> A LinkButton activates the fade in jQuery via $("#lnkDocumentUpload").click(function() { centerPopup(); loadPopup(); });

  • Using Qt's XML library for simple operation

    - by David Powers
    I basically want to use the XML parser from Qt in my existing project. I have only used Qt once before, and that was with Qt Designer, and I am not having much luck finding anything on Google about how to just use the XML library. I have downloaded a web page that has one large list, and I want to parse it and add each list item to a c++ list. I found this sample code on Ubuntu forums... http://www.uluga.ubuntuforums.org/showpost.php?p=9112973&postcount=6 I want to use that except I need to know what exactly I need to add to the project to get access to it. One other small question is QDomDocument seems to be for files (makes sense) but I have the XML in a string. What part of the XML library works for contents of a string?

  • WPF Application - Role Management Recommendations

    - by David Ward
    I have a WPF application with a WCF service layer and a SQL database. I now want to restrict elements of the application so that certain functions are only available to those users with a particular role. For example, you will only be able to navigate to the settings screen if you are an administrator. I would like a user to be a member of 1 or more authorisation groups and each authorisation group to have 1 or more roles associated. A long time ago I used AzMan (Authorisation Manager) to do a similar thing. Does anyone think that there are better approaches? Is AzMan "old news"? Alternatives? Thanks.

  • How do I prevent a font from extending off the top of a textbox?

    - by David Ellis
    I'm using a barcode font (IDAutomationMC39H) in an SSRS 2005 report I'm developing, and while it renders fine in the preview in BIDS, if I export the results to PDF, print the results, or do any of the above (including preview) in Report Manager, the barcode font is extending off the top of the textbox. The barcode itself is nearly 20px tall, even at only a 12pt size. I've tried changing the CanGrow value for the textbox, but it seems that even with that set off the barcode isn't pushing the bottom edge of the textbox downwards, it's simply extending over the top of the box. I've also tried resizing the textbox to allow it to contain the entire height of the font, but even with the VerticalAlign set to Bottom the barcode still sticks to the top of the textbox and overflows out the top. See screenshot here: http://bit.ly/9UfycP Does anyone know how to force the font to be bound by the top of the box, instead of overlapping it?

  • Using struts.xml with convention plugin

    - by David Alt
    This seems like it should be easy to do, but I just can make it work. I'm hooked on the convention plugin in Struts 2.1. However, I need to define some package-level configuration such as a new interceptor stack and exception mappings. I'd like to use the struts.xml file for this, but I can't get the convention-based packages matched to the struts.xml packages. My struts.xml looks like: <struts> <constant name="struts.convention.default.parent.package" value="default"/> <package name="default" extends="struts-default"> </package> <package name="root" namespace="/" extends="struts-default"> <action name="index"> <result>/index.jsp</result> </action> </package> <package name="my.package.actions.myaccount" namespace="/myaccount" extends="struts-default"> <interceptors> <interceptor name="authenticationInterceptor" class="my.package.interceptors.AuthenticationInterceptor"/> <interceptor-stack name="secureStack"> <interceptor-ref name="authenticationInterceptor"/> <interceptor-ref name="defaultStack"/> </interceptor-stack> </interceptors> <default-interceptor-ref name="secureStack"/> </package> </struts> I have my interceptor in: /src/my/package/interceptors and my actions in: /src/my/package/actions/myaccount
