  • BackgroundWorker and Progressbar.Show()

    - by Juergen
    Hi, I am using Visual Studio 2010 and C# and try to get my progressbar to show but it doesn't work. I listen to an event. If it happens I want to do some work and show a progressbar while doing that. This is what I do: static void Main(string[] args) { ProgressForm form = new ProgressForm(); new FileWatcher(form).Start(); Application.Run(); } ProgressForm: bgWorker.DoWork += new DoWorkEventHandler(bgWorker_DoWork); private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { this.Show(); .... } but nothing shows. Why isn't that working? thanks bye juergen

  • any way to get sharepoint groups with a given site url

    - by standley-nguyen
    Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

  • Caching the repository index in m2eclipse

    - by Titi Wangsa bin Damhore
    everytime i start with a fresh new workspace, m2eclipse downloads nexus-maven-repository-index.gz from the maven central repository. this is good. but, some times, i just want to start a new workspace, and not wait for it to download, it tried copying the whole .metadata directory from an old workspace to the new one, but the list of maven artifacts are still empty. is there a way i can cache it? or at least download the file once, and the copy/extract/repackage it so that m2eclipse thinks it has already downloaded it and allows me to search for maven artifacts. or a short version of the question where and in what format is the "nexus-maven-repository-index.gz" file stored in the workspace?

  • How to get List of results from list of ID values with LINQ to SQL?

    - by DaveDev
    I have a list of ID values: List<int> MyIDs { get; set; } I'd like to pass this list to an interface to my repository and have it return a List that match the ID values I pass in. List<MyType> myTypes = new List<MyType>(); IMyRepository myRepos = new SqlMyRepository(); myTypes = myRepos.GetMyTypes(this.MyIDs); Currently, GetMyTypes() behaves similarly to this: public MyType GetMyTypes(int id) { return (from myType in db.MyTypes where myType.Id == id select new MyType { MyValue = myType.MyValue }).FirstOrDefault(); } where I iterate through MyIDs and pass each id in and add each result to a list. How do I need to change the LINQ so that I can pass in the full list of MyIDs and get a list of MyTypes out? GetMyTypes() would have a signature similar to public List<MyType> GetMyTypes(List<int> myIds)

  • Send post data while opening SSE connection

    - by Prosto Trader
    I'm trying to establish SSE connection and do some long-taking actions on server-side, informing user about how it goes through SSE events. Actually, I don't understand how would I send some data along with new connection. I have to combine regular ajax with new EventSource or there is a way to transfer post data inside that event? Here is what I have so far, and I need to send pretty big JSON with the request. Is it possible or the only way to send data is GET? var source = new EventSource('/terminal/ajax-put-packet-trade-order/');

  • Can't get a SQL command to recognise the params added

    - by littlechris
    Hi, I've not used basic SQL commands for a while and I'm trying to pass a param to a sproc and the run it. However when I run the code I get a "Not Supplied" error. Code: SqlConnection conn1 = new SqlConnection(DAL.getConnectionStr()); SqlCommand cmd1 = new SqlCommand("SProc_Item_GetByID", conn1); cmd1.Parameters.Add(new SqlParameter("@ID", itemId)); conn1.Open(); cmd1.ExecuteNonQuery(); I'm not really sure why this would fail. Apologies for the basic question, but I'm lost! Thanks in advance.

  • multiple C++ deletion of a memory pointed by multiple objects

    - by elgcom
    Another c++ pointer deletion question is in the following example: class Foo { public: int *p; ~Foo() { delete p; p = NULL; } }; Foo *f1 = new Foo(); Foo *f2 = new Foo(); f1->p = new int(1); f2->p = f1->p; delete f2; // ok delete f1; // no error? Why I did not get error when calling "delete f1"? didn't I delete the same address (*p) twice? If I directly delete the pointers in the last 2 lines of code, I will get error. delete f2->p; // ok delete f1->p; // error!! *** glibc detected *** double free or corruption (fasttop) ***

  • Hibernate multi column discriminator

    - by shikarishambu
    I have a single lookup table that manages all lookups - legacy and new lookup table structure is context,name, code, value context is either legacy or new name is the name of the lookup - state, status etc...for example code is the code and value is the value associated with the code Is there a way to specify multiple columns as discriminators so that I can get all legacy state code/values or all new status code/values. Is there a different way to do this if discriminators cannot do it? <class name="com.company.domain.Lookup"> <id name="Id" column="id" type="big_integer"> <generator class="org.hibernate.id.TableHiLoGenerator" /> </id> <discriminator column="context" insert="false" /> <property name="code" type="string"/> <property name="value" type="string"/> <property name="desc" type="string"/> <subclass name="com.company.domain.LegacyLookup" discriminator-value="legacy">

  • Entity Framework 5 not updating navigation properties in both entities

    - by Taylor
    I have updated a project to use the new Entity framework shipped with VS2012, however I have run into some of my code throwing exceptions. In the VS10 version of EF I was able to create or modify and Entity and use its navigation properties before calling SaveChanges() For example: A Navigation property of a client having a collection of Invoices. Client c = new Client(); Invoice I = new Invoice(); c.Invoices.Add(I); I would then be able to use Invoice.Client somewhere in my code before actually saving it without issue. Now Invoice.Client == null. Similarly in setting I.Client = C, I does not show up under C.Invoices What am I missing here or is this just simply how EF5 is?

  • Adding a subdomain to my google app engine project?

    - by user246114
    Hi, I created a google app engine project. I just successfully mapped it to a new domain. The name of my project is "grape". So by default, it is published at http://www.grape.appspot.com. I mapped it to http://www.grape.com, which is terrific. Now I'd like to create a new app engine project, and have it mapped to: http://api.grape.com how do I go about doing this? I think it is possible, I'm just not sure where I would do this mapping? Since I own grape.com, I am hoping I can map a new project to t. The basic idea was to have one project which is responsible for the UI stuff, then a second project responsible just for a public api, which would be great, Thanks

  • Correct redirect after posting comment - django comments framework

    - by Sachin
    I am using django comments framework for allowing users to comment on my site, but there is a problem with the url to which user is redirected after posting the comment. If I render my comment form as {% with comment.content_object.get_absolute_url as next %} {% render_comment_form for comment.content_object %} {% endwith %} Then the url to which it is redirected after the comment is posted is <comment.content_object.get_absolute_url/?c=<comment.id> For example I posted a comment on a post with url /post/256/a-new-post/ then the url to which I am redirected after posting the comment is /post/256/a-new-post/?c=99 where assume 99 is the id comment just posted. Instead what I want is something like this /post/256/a-new-post/#c99. Secondly when I do comment.get_absolute_url() I do not get the proper url instead I get a url like /comments/cr/58/14/#c99 and this link is broken. How can I get the correct url as mentioned in the documentation. Am i doing something wrong. Any help is appreciated.

  • Set Validation Tooltip in CodeBehind instead of XAML

    - by KrisTrip
    I would like to know how to translate the following code to codebehind instead of XAML: <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> The part I can't figure out is the Path portion. I have the following but it doesn't work: new Trigger { Property = Validation.HasErrorProperty, Value = true, Setters = { new Setter { Property = Control.ToolTipProperty, // This part doesn't seem to work Value = new Binding("(Validation.Errors)[0].ErrorContent"){RelativeSource = RelativeSource.Self} } } } Help?

  • Difficulty to start up with basic unit test (Sample from my book -- SportsStore)

    - by Richard77
    Hello, I'm really new in TDD and, actually, I'm trying to follow the sample from my book (SportsStore -- Pro ASP.NET MVC Framework/Steve Sanderson/APRESS). I'm on pages 103-105. Although there are more on this, as new to all of this, I'm concerned with the following statements. ProductsController controller = new ProductsController(repository); var result = controller.List(2); //... regarding the above statements, when I write this (as in the book), var products = result.ViewData.Model as IList<Product>; I get a compiler error "System.Web.MVC.ActionResult" does not contain a definition for ViewData ..." But, when I remove the List() from the statement, then the compiler error disapear. var result = controller.List(2);//Doesn't work var result = controller;//It works Is something wrong there? I checked Apress website for that book, but there is nothing listed as Errata or issue. So I'm really lost. Thanks for helping

  • How do I assign by "reference" to a class field in c#?

    - by Jamie
    I am trying to understand how to assign by "reference" to a class field in c#. I have the follwing example to consider: public class X { public X() { string example = "X"; new Y( ref example ); new Z( ref example ); System.Diagnostics.Debug.WriteLine( example ); } } public class Y { public Y( ref string example ) { example += " (Updated By Y)"; } } public class Z { private string _Example; public Z( ref string example ) { this._Example = example; this._Example += " (Updated By Z)"; } } var x = new X(); When running the above code the output is: X (Updated By Y) And not: X (Updated By Y) (Updated By Z) As I had hoped. It seems that assigning a "ref parameter" to a field loses the reference. Is there any way to keep hold of the reference when assigning to a field? Thanks.

  • passing parameter to view in IOS after a button is pressed

    - by ghostrider
    I am new to IOS programming. So far I have been programming in android. So in android when pressing a button code for passing an argument would be like that: Intent i = new Intent(MainScreen.this,OtherScreen.class); Bundle b = new Bundle(); b.putString("data_1",data); i.putExtras(b); startActivity(i); and on the activity that opens, i would write something like this: Bundle b = getIntent().getExtras(); ski_center=b.getString("data_1"); what methods should I need to change in MainScreen and in OtherScreen in IOS to achieve the above. Basically I will have 3 buttons lets say in my MainScreen and each of it will open the Otherview but each time a different parameter will be passed. Foe example for each button i have code like these in MainScreen.m @synthesize fl; -(IBAction) ifl:(id) sender { } So I need your help in where to place the "missing" code, too.

  • MySql / Odbc connection problem

    - by Ingvald
    I'm accessing a MySql database via ODBC. It normally works fine, but if the database is stopped and restarted I have to restart my application in order to reconnect to the database. The code for accessing the database is like this: OdbcConnection connection = new OdbcConnection(connectString); OdbcCommand command = connection.CreateCommand(); command.CommandType = CommandType.Text; command.CommandText = "select * from cds"; OdbcDataAdapter dataAdapter = new OdbcDataAdapter(command); DataSet dataSet = new DataSet(); connection.Open(); dataAdapter.Fill(dataSet); connection.Close(); After a restart of the database, I get a 'MySql server has gone away' exception in dataAdapter.Fill method. Is there any way I can reconnect to the database when I detect that the connection has broken? I use VS2008 and MySql 5.1.30.

  • Login fails after upgrade to ASP.net 4.0 from 3.5

    - by lomac
    I cannot log in using any of the membership accounts using .net 4.0 version of the app. It fails like it's the wrong password, and FailedPasswordAttemptCount is incremented in my_aspnet_membership table. (I am using membership with mysql membership provider.) I can create new users. They appear in the database. But I cannot log in using the new user credentials (yes, IsApproved is 1). One clue is that the hashed passwords in the database is longer for the users created using the asp.net 4.0 version, e.g 3lwRden4e4Cm+cWVY/spa8oC3XGiKyQ2UWs5fxQ5l7g=, and the old .net 3.5 ones are all like +JQf1EcttK+3fZiFpbBANKVa92c=. I can still log in when connecting to the same db with the .net 3.5 version, but only to the old accounts, not the new ones created with the .net 4.0 version. The 4.0 version cannot log in to any accounts. I tried dropping the whole database on my test system, the membership tables are then auto created on first run, but it's still the same, can create users, but can't log in.
