  • How to align Buttons in a TableLayout to different directions?

    - by Bevor
    Hello, probably I don't understand the layout properties of TableLayout yet. It doesn't seem to be possible to achieve such a flexible table like in HTML, because there are no cells. My target is it to achieve such a layout: Link to draft How can I do that? I thought about using a GridView but this doesn't seem to be useful in XML. My efforts look like this: <TableLayout android:id="@+id/tableLayout" android:layout_width="320sp" android:layout_height="fill_parent" android:layout_gravity="center_horizontal" android:gravity="bottom" android:layout_alignParentBottom="true"> <TableRow android:background="#333333" android:gravity="bottom" android:layout_width="fill_parent"> <Button android:id="@+id/btnUp" android:layout_width="60sp" android:layout_height="50sp" android:gravity="left" android:text="Lift U" /> <Button android:id="@+id/btnScreenUp" android:gravity="right" android:layout_gravity="right" android:layout_width="60sp" android:layout_height="50sp" android:text="Scrn U" /> </TableRow> <TableRow android:background="#444444" android:gravity="bottom" android:layout_gravity="right"> <Button android:id="@+id/btnDown" android:layout_width="60sp" android:layout_height="50sp" android:text="Lift D" /> <Button android:id="@+id/btnScreenLeft" android:layout_width="60sp" android:layout_height="50sp" android:gravity="right" android:layout_gravity="right" android:text="Scrn L" /> <Button android:id="@+id/btnScreenDown" android:layout_width="60sp" android:layout_height="50sp" android:gravity="right" android:layout_gravity="right" android:text="Scrn D" /> <Button android:id="@+id/btnScreenRight" android:layout_width="60sp" android:layout_height="50sp" android:gravity="right" android:layout_gravity="right" android:text="Scrn R" /> </TableRow> </TableLayout>

  • WPF Datagrid -DataGridTemplateColumn tab focus issue

    I am using Microsoft WPF datagrid. I have noticed a strange behavior with WPF datagrid DataGridTemplateColumn. When you use the templateColumn in the grid and the template column contains some controls when you tab from the previous column the focus is not automatically given to the first element declared in the template column. The foucs is initally set on the border of the template column and when we tab of once agin the focus goes to the first column. Any workaround for this issue. How can i set the focus to go the first element in the template column of the datagrid when i tab off.

  • Syntax error on token "QUOTE", VariableDeclaratorId expected after this token

    - by user356812
    I've posted a bigger chunk of the code below. You can see that initially QUOTE was procedural- coded in place. I'm trying to learn how to use declarative design so I want to do the same thing but by using resources. It seems like I need to access the string.xml thru the @R.id tag and identify QUOTE with that string value. But I don't know enough to negotiate this. Any tips? Thanks! public class circle extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new GraphicsView(this)); } static public class GraphicsView extends View { //private static final String QUOTE = "Happy Birthday to David."; private final String QUOTE = getString(R.string.quote); ..... @Override protected void onDraw(Canvas canvas) { // Drawing commands go here canvas.drawPath(circle, cPaint); canvas.drawTextOnPath(QUOTE, circle, 0, 20, tPaint);

Anyways I'm trying to figure out why it throws the error: Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1 When the arrays clearly have all those elements, I even logged their size and it says 100. Any help/guidance would be greatly appreciated.

  • SoapHttpClientProtocol disable ssl certificate validation

    - by MK
    I need to tell my C# soap web service consumer to not validate the certificate and just accept it. Is this possible? Why: we publish a https-only web service. A client needs to consume it but has some kind of firewall/proxy (WebSense?) which does something to the certificate to make it fail validation. At this point I don't even know the details of what it does, but the customer appears to be ok with forfeiting the benefits of SSL, so I'm looking for a workaround.

  • Spring Security session-management setting and IllegalStateException

    - by JayL
    I'm trying to add <session-management> in my Spring Security namespace configuration so that I can provide a different message than the login page when the session times out. As soon as I add it to my configuration it starts throwing "IllegalStateException: Cannot create a session after the response has been committed" when I access the app. I'm using Spring Security 3 and Tomcat 6. Here's my configuration: <http> <intercept-url pattern="/go.htm" access="ROLE_RESPONDENT" /> <intercept-url pattern="/complete.htm" access="ROLE_RESPONDENT" /> <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" /> <form-login login-processing-url="/j_spring_security_check" login-page="/login.htm" authentication-failure-url="/login.htm?error=true" default-target-url="/go.htm" /> <anonymous/> <logout logout-success-url="/logout_message.htm"/> <session-management invalid-session-url="/login.htm" /> </http> Everything works great until I add in the <session-management> line. What am I missing?

  • Simplest way to create busy animation in WPF

    - by drasto
    I mentioned that there is no standard busy control in WPF. So what's the easiest way to display animated busy circle (not progress bar) such as your browser displays when loading a page ? Please if you suggest downloading control from internet make sure that this control is for free and with no licence restriction (such as I would be forced to GPL my application if I use it). Thank you in advance

  • How to use Application Verifier to find memory leaks

    - by Patrick
    I want to find memory leaks in my application using standard utilities. Previously I used my own memory allocator, but other people (yes, you Neil) suggested to use Microsoft's Application Verifier, but I can't seem to get it to report my leaks. I have the following simple application: #include <iostream> #include <conio.h> class X { public: X::X() : m_value(123) {} private: int m_value; }; void main() { X *p1 = 0; X *p2 = 0; X *p3 = 0; p1 = new X(); p2 = new X(); p3 = new X(); delete p1; delete p3; } This test clearly contains a memory leak: p2 is new'd but not deleted. I build the executable using the following command lines: cl /c /EHsc /Zi /Od /MDd test.cpp link /debug test.obj I downloaded Application Verifier (4.0.0665) and enabled all checks. If I now run my test application I can see a log of it in Application Verifier, but I don't see the memory leak. Questions: Why doesn't Application Verifier report a leak? Or isn't Application Verifier really intended to find leaks? If it isn't which other tools are available to clearly report leaks at the end of the application (i.e. not by taking regular snapshots and comparing them since this is not possible in an application taking 1GB or more), including the call stack of the place of allocation (so not the simple leak reporting at the end of the CRT) If I don't find a decent utility, I still have to rely on my own memory manager (which does it perfectly).

  • Vimdiff with git mergetool error: "More than two buffers in diff mode"

    - by Elizabeth Buckwalter
    I've read Vimdiff and Viewing differences with Vimdiff plus doing various google searches using things like "vimdiff multiple", "vimdiff git", "vimdiff commands" etc. When using do or diffg I get the error "More than two buffers in diff mode, don't know which one to use". When using diffg v:fname_in I get "No matching buffer for v:fname_in". From the vimdiff documentation: :[range]diffg[et] [bufspec] Modify the current buffer to undo difference with another buffer. If [bufspec] is given, that buffer is used. If [bufspec] refers to the current buffer then nothing happens. Otherwise this only works if there is one other buffer in diff mode. and more: When 'diffexpr' is not empty, Vim evaluates to obtain a diff file in the format mentioned. These variables are set to the file names used: v:fname_in original file v:fname_new new version of the same file v:fname_out resulting diff file So, I need to get the name of bufspec, but the default variables (fname_in, fname_new, and fname_out) aren't set. I ran the command git mergetool on a linux box through a terminal.

  • Replacing build.xml with Build.java - using Java and the Ant libraries as a build system

    - by Dean Schulze
    I've grown disillusioned with Groovy based alternatives to Ant. AntBuilder doesn't work from within Eclipse, the Groovy plugin for Eclipse is disappointing, and Gradle just isn't ready yet. The Ant documentation has a section titled "Using Ant Tasks Outside of Ant" which gives a teaser for how to use the Ant libraries from Java code. There's another example here: http://www.mail-archive.com/[email protected]/msg16310.html In theory it seems simple enough to replace build.xml with Build.java. The Ant documentation hints at some undocumented dependencies that I'll have to discover (undocumented from the point of view of using Ant from within Java). Given the level of disappointment with Ant scripting, I wonder why this hasn't been done before. Perhaps it has and isn't a good build system. Has anyone tried writing build files in Java using the Ant libraries?

  • Android - Using PreferenceScreen to display and save settings to/from ContentProvider

    - by Donal Rafferty
    I have my own custom Content Provider that loads a datasbase which contains the settings information for my application. I load the settings from the ContentProvider on the creation of my Settings activity. My Settings activity is made up of a PreferenceScreen and Dialog based EditText's. The following code shows how I use the preference screen and edit texts. So as you can see from the first image this works and displays the menu with the information underneath. The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog. I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider. Can anyone help me with what I'm trying to do? Code // Root PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this); // Dialog based preferences PreferenceCategory dialogBasedPrefCat = new PreferenceCategory(this); dialogBasedPrefCat.setTitle(R.string.dialog_based_preferences); root.addPreference(dialogBasedPrefCat); // Edit text preference EditTextPreference editTextPref = new EditTextPreference(this); editTextPref.setDialogTitle(R.string.dialog_title_edittext_preference); editTextPref.setKey("edittext_preference"); editTextPref.setTitle(R.string.title_edittext_preference); editTextPref.setSummary(name); dialogBasedPrefCat.addPreference(editTextPref); Image One Image Two

  • Having the output of a Console App in Visual Studio instead of the Console

    - by devoured elysium
    When doing "Console" apps in Java with Eclipse, I see the output being put in a text box on the IDE itself, instead of having a Console popping up like in Visual Studio. This comes in handy, as even after the program has exited, I can still make good use of the text that was written in it, as it doesn't get erased until I run it again. Is it possible to achieve anything like that with Visual Studio? I know that instead of doing System.Console.WriteLine(str); I can do System.Diagnostics.Debug.WriteLine(str); but it is not quite the same thing, as you get a lot of "junk" in the Output window, as all the loaded symbols and such. Even better, is it possible to have everything done in the IDE itself, when you run your app, instead of having the Console running? Thanks

  • How to marshal int* in C#?

    - by MartyIX
    Hi, I would like to call this method in unmanaged library: void __stdcall GetConstraints( unsigned int* puiMaxWidth, unsigned int* puiMaxHeight, unsigned int* puiMaxBoxes ); My solution: Delegate definition: [UnmanagedFunctionPointer(CallingConvention.StdCall)] private delegate void GetConstraintsDel(UIntPtr puiMaxWidth, UIntPtr puiMaxHeight, UIntPtr puiMaxBoxes); The call of the method: // PLUGIN NAME GetConstraintsDel getConstraints = (GetConstraintsDel)Marshal.GetDelegateForFunctionPointer(pAddressOfFunctionToCall, typeof(GetConstraintsDel)); uint maxWidth, maxHeight, maxBoxes; unsafe { UIntPtr a = new UIntPtr(&maxWidth); UIntPtr b = new UIntPtr(&maxHeight); UIntPtr c = new UIntPtr(&maxBoxes); getConstraints(a, b, c); } It works but I have to allow "unsafe" flag. Is there a solution without unsafe code? Or is this solution ok? I don't quite understand the implications of setting the project with unsafe flag. Thanks for help!

  • Silverlight 4 OOB application access HTML DOM of the page in WebBrowser control

    - by Mike Weerasinghe
    Does anybody know if it is possible to access and manipulate an element in the html page that is rendered by the Silverlight 4 WebBrowser control. The scenario is like this. The user launches a Silverlight OOB application with elevated trust. The user manipulates some data in the application but must submit part of the data to an external web site. If I open the external site in a WebBrowser control, is there any way I can assist the user by pre filling some information in the external sites' web form via programmatic access to the DOM?

    Rails has the rest autho plugin which works well but is there a solution for incorporating twitter, facebook, google, yahoo, etc... Seems like each on has its own plugin and demands and mixing them is going to be a mess. This is for logging in users like how Stackoverflow gets things done not for using the robust features of the APIs. What I want to do is do what stackoverflow did for login but in rails.

  • OS X, Mercurial and MediaTemple problem

  • WCF security via message headers

    - by exalted
    I'm trying to implement "some sort of" server-client & zero-config security for some WCF service. The best (as well as easiest to me) solution that I found on www is the one described at http://www.dotnetjack.com/post/Automate-passing-valuable-information-in-WCF-headers.aspx (client-side) and http://www.dotnetjack.com/post/Processing-custom-WCF-header-values-at-server-side.aspx (corrisponding server-side). Below is my implementation for RequestAuth (descibed in the first link above): using System; using System.Diagnostics; using System.ServiceModel; using System.ServiceModel.Configuration; using System.ServiceModel.Dispatcher; using System.ServiceModel.Description; using System.ServiceModel.Channels; namespace AuthLibrary { /// <summary> /// Ref: http://www.dotnetjack.com/post/Automate-passing-valuable-information-in-WCF-headers.aspx /// </summary> public class RequestAuth : BehaviorExtensionElement, IClientMessageInspector, IEndpointBehavior { [DebuggerBrowsable(DebuggerBrowsableState.Never)] private string headerName = "AuthKey"; [DebuggerBrowsable(DebuggerBrowsableState.Never)] private string headerNamespace = "http://some.url"; public override Type BehaviorType { get { return typeof(RequestAuth); } } protected override object CreateBehavior() { return new RequestAuth(); } #region IClientMessageInspector Members // Keeping in mind that I am SENDING something to the server, // I only need to implement the BeforeSendRequest method public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState) { throw new NotImplementedException(); } public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel) { MessageHeader<string> header = new MessageHeader<string>(); header.Actor = "Anyone"; header.Content = "TopSecretKey"; //Creating an untyped header to add to the WCF context MessageHeader unTypedHeader = header.GetUntypedHeader(headerName, headerNamespace); //Add the header to the current request request.Headers.Add(unTypedHeader); return null; } #endregion #region IEndpointBehavior Members public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters) { throw new NotImplementedException(); } public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime) { clientRuntime.MessageInspectors.Add(this); } public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { throw new NotImplementedException(); } public void Validate(ServiceEndpoint endpoint) { throw new NotImplementedException(); } #endregion } } So first I put this code in my client WinForms application, but then I had problems signing it, because I had to sign also all third-party references eventhough http://msdn.microsoft.com/en-us/library/h4fa028b(v=VS.80).aspx at section "What Should Not Be Strong-Named" states: In general, you should avoid strong-naming application EXE assemblies. A strongly named application or component cannot reference a weak-named component, so strong-naming an EXE prevents the EXE from referencing weak-named DLLs that are deployed with the application. For this reason, the Visual Studio project system does not strong-name application EXEs. Instead, it strong-names the Application manifest, which internally points to the weak-named application EXE. I expected VS to avoid this problem, but I had no luck there, it complained about all the unsigned references, so I created a separate "WCF Service Library" project inside my solution containing only code above and signed that one. At this point entire solution compiled just okay. And here's my problem: When I fired up "WCF Service Configuration Editor" I was able to add new behavior element extension (say "AuthExtension"), but then when I tried to add that extension to my end point behavior it gives me: Exception has been thrown by the target of an invocation. So I'm stuck here. Any ideas?

  • Android TabHost: update tabs from tab's activity

    - by joshuadlillie
    I have a TabActivity and am going to have 3 or 4 tabs. In TabA, I would like to have an ExpandableListView, which will list products. I would like TabC to act as a sort of "shopping cart", probably with a ListView of itself. So, my question is: is there a way to interact with the TabHost from the Activity? I would like to be able to click a button inside of TabA and have it update and switch to TabC. Is this possible? Can I get the Tab's activities call it's parents methods?

    Dear Telerik Team, When I am trying to display data using radgrid I am getting error like "Index was out of range. Must be non-negative and less than the size of the collection. Parameter: Index". Here is my code <telerik:RadGrid ID="gvCktMap" BorderColor="White" runat="server" AutoGenerateColumns="true" AllowSorting="true" BackColor="White" AllowPaging="true" PageSize="25" GridLines="None" OnPageIndexChanging="gvCktMap_PageIndexChanging" OnRowCancelingEdit="gvCktMap_RowCancelingEdit" OnRowCommand="gvCktMap_RowCommand" OnRowUpdating="gvCktMap_RowUpdating" OnRowDataBound="gvCktMap_RowDataBound" OnSorting="gvCktMap_Sorting" OnRowEditing="gvCktMap_RowEditing" ShowGroupPanel="True" EnableHeaderContextMenu="true" EnableHeaderContextFilterMenu="true" AllowMultiRowSelection="true" AllowFilteringByColumn="True" AllowCustomPaging="false" OnItemCreated="gvCktMap_ItemCreated" EnableViewState="false" OnNeedDataSource="gvCktMap_NeedDataSource" OnItemUpdated="gvCktMap_ItemUpdated" > <MasterTableView DataKeyNames="sId" UseAllDataFields="true"> <Columns> <telerik:GridBoundColumn UniqueName="sId" HeaderText="sId" DataField="sId" Visible="false"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="orderId" HeaderText="orderId" DataField="orderId"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="REJ" HeaderText="REJ" DataField="REJ"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="Desc" HeaderText="Desc" DataField="Desc"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="CustomerName" HeaderText="CustomerName" DataField="CustomerName"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="MarketName" HeaderText="MarketName" DataField="MarketName"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="HeadendName" HeaderText="HeadendName" DataField="HeadendName"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="SiteName" HeaderText="SiteName" DataField="SiteName"> </telerik:GridBoundColumn> <telerik:GridBoundColumn UniqueName="TaskStatus" HeaderText="TaskStatus" DataField="TaskStatus"> </telerik:GridBoundColumn> </Columns> </telerik:RadGrid> Here is my code behind private void bingGrid() { try { gvCktMap.Columns.Clear(); DataSet dsResult = new DataSet(); DataSet dsEditItems = new DataSet(); dsEditItems.ReadXml(Server.MapPath("XMLS/" + Session["TaskID"].ToString() + ".xml")); clsSearch_BL clsObj = new clsSearch_BL(); clsObj.TaskID = (string)Session["TaskID"]; clsObj.CustName = (string)Session["CustName"]; clsObj.MarketName = (string)Session["MarketName"]; clsObj.HeadendName = (string)Session["HeadendName"]; clsObj.SiteName = (string)Session["SiteName"]; clsObj.TaskStatus = (string)Session["TaskStatus"]; clsObj.OrdType = (string)Session["OrdType"]; clsObj.OrdStatus = (string)Session["OrdStatus"]; clsObj.ProName = (string)Session["ProName"]; clsObj.LOC = (string)Session["LOC"]; dsResult = clsObj.getSearchResults_BL(clsObj); Session["SearchRes"] = dsResult; DataTable dtFilter = new DataTable(); DataColumn dtCol = new DataColumn("FilterBy"); dtFilter.Columns.Add(dtCol); dtCol = new DataColumn("DataType"); dtFilter.Columns.Add(dtCol); gvCktMap.DataSource = dsResult; gvCktMap.DataBind(); } catch (Exception ex) { } } If i remove <MasterTableView></MasterTableView> Its working fine without any error. But for some reasons i need to use <MasterTableView></MasterTableView> Can anyone help me out to fix this error. Thanks In Advance
