  • Why is my ServiceOperation method missing from my WCF Data Services client proxy code?

    - by Kev
    I have a simple WCF Data Services service and I want to expose a Service Operation as follows: [System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)] public class ConfigurationData : DataService<ProductRepository> { // This method is called only once to initialize service-wide policies. public static void InitializeService(IDataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.ReadMultiple | EntitySetRights.ReadSingle); config.SetServiceOperationAccessRule("*", ServiceOperationRights.All); config.UseVerboseErrors = true; } // This operation isn't getting generated client side [WebGet] public IQueryable<Product> GetProducts() { // Simple example for testing return (new ProductRepository()).Product; } Why isn't the GetProducts method visible when I add the service reference on the client?

  • Implementing IPermission

    - by joniba
    Hi there, I'm considering writing a custom IPermission implementation but am not clear as to how it should work. I've already implemented IPrincipal and IIdentity. What I would like to accomplish is to be able to check permissions vis a vis the current IPrincipal's authorizations rather than its roles. Generally, authorizations are read/add-delete/update/none for a given type. So I would like to write something like this: [CustomPermission(SecurityAction.Demand, Type = typeof(Foo), MinimumAuthorization = AuthorizationFlags.Read)] public void SomeMethod(){} Is this possible? I've looked over the code at http://msdn.microsoft.com/en-us/library/system.security.ipermission.aspx. This shows how to implement the interface, but I don't understand how the above pseudo-code would be able to check against the IPrincipal's authorizations for the type. Any help or resource references would be appreciated. Joni

  • Visual Studio 2008 built-in web server needs integrated pipeline mode - How?

    - by jdk
    Using Visual Studio 2008 and built-in web server. In a Web Handler .ashx file public void ProcessRequest(HttpContext context) { context.Response.ContentType = MimeType_text_xvcard; context.Response.Headers.Add(HttpHeader_ContentLength, "2138"); when I try to add an HTTP header I get the exception: This operation requires IIS integrated pipeline mode. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.PlatformNotSupportedException: This operation requires IIS integrated pipeline mode. I can find information about this error on the Internet but need specific info about how to presumably enable Integrated Pipeline mode (through web.config?) to allow HTTP headers to be manipulated. How do do I put the built-in web server into integrated pipeline mode? Note: Not using full-fledged IIS

  • Check if thread is EDT is necessary?

    - by YuppieNetworking
    Hello, I have an UI implemented with Swing. One component does some work that may take some time, so I use SwingUtilities.invokeLater. However, I was reading some old code and found this in an ActionListener: if (!SwingUtilities.isEventDispatchThread()) { SwingUtilities.invokeLater(new Runnable() { public void run() { // code X } }); } else { // code X } I thought that it made sense since it separates code X from the EDT. However, I found it error-prone since I have used it a couple of times and both times I forgot the else part. The question is: is the SwingUtilities.isEventDispatchThread() checking necessary? Or could I assume that I am not in the EDT and always use invokeLater? Thanks a lot.

  • What does msvc 6 throw when an integer divide by zero occurs?

    - by EvilTeach
    I have been doing a bit of experimenting, and have discovered that an exception is being thrown, when an integer divide by zero occurs. #include <iostream> #include <stdexcept> using namespace std; int main ( void ) { try { int x = 3; int y = 0; int z = x / y; cout << "Didn't throw or signal" << endl; } catch (std::exception &e) { cout << "Caught exception " << e.what() << endl; } return 0; } Clearly it is not throwing a std::exception. What else might it be throwing?

  • Java Timers - Messing up function called?

    - by Matt Swanson
    So I have a TimerTask task calling a function onTimerComplete() in its run() onTimerComplete() looks something like this: private void onTimerComplete(){ myFunc1(); myFunc2(); } I make a Timer t and I schedule the TimerTask with t.schedule(task, 2000); The problem is, when the timer is up and the task runs my onTimerComplete() but that function does not finish. It runs myFunc1() but never finishes it nor does it ever call myFunc2() However, if I call onTimerComplete() directly, everything works. What's the deal here?

  • How to specify argument attributes in CFscript? (CF9)

    - by Henry
    In CF9 doc: Defining components and functions in CFScript, it says: /** *Comment text, treated as a hint. *Set metadata, including, optionally, attributes, in the last entries *in the comment block, as follows: *@metadataName metadataValue ... */ access returnType function functionName(arg1Type arg1Name="defaultValue1" arg1Attribute="attributeValue...,arg2Type arg2Name="defaultValue2" arg2Attribute="attributeValue...,...) functionAttributeName="attributeValue" ... { body contents } How do you specify arg1Attribute? I tried this: public void function setFirstname(string firstname="" displayName="first name"){} but it does NOT work. Also, how do you translate this to script-style? <cffunction name="setPerson"> <cfargument name="person" type="com.Person"/> </cffunction> I tried: function setPerson(com.Person person){} and it does NOT work either. "You cannot use a variable reference with "." operators in this context" it says.

  • C# Progressbar is not updated accurately in Vista or Windows7

    - by Samir
    private void timer1_Tick(object sender, EventArgs e) { if (this.progressBar1.Value >= 100) { this.timer1.Stop(); this.timer1.Enabled = false; } else { this.progressBar1.Value += 10; this.label1.Text = Convert.ToString(this.progressBar1.Value); } } Here I used a timer to update the progress bar value. It works fine in XP. But in Windows7 or Vista when the progress value is set to say 100 but the graphical progress is not 100! Searching some threads found that its for animation lag in Vista/Windows7. How to get rid of this thing? I don't want to loose the look and feel of Vista/Window7 using: SetWindowTheme(progressBar1.Handle, " ", " ");

  • How Gridview co-operates with ObjectDataSource?

    - by sanjuro
    Hi, how Gridview co-operates with ObjectDataSource internally? When you set DataSourceID of GridView, assigned ObjectDataSource take care of such things as paging and sorting, but i don't have full control above databinding itself, on the other side when i set datasource of gridview in code-behind: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } Now i have full control, but i have lost the advantage of comfort sorting and paging. And that co-operation between ObjectDataSource and Gridview became mystery for me. So can anybody explain me in details how ObjectDataSource and Gridview co-operates under the hood? I want to understand it in order to write my own smart code or own gridview that will mimic this co-operation. Many thanks for answers.

  • adding nodes to a binary search tree randomly deletes nodes

    - by SDLFunTimes
    Hi, stack. I've got a binary tree of type TYPE (TYPE is a typedef of data*) that can add and remove elements. However for some reason certain values added will overwrite previous elements. Here's my code with examples of it inserting without overwriting elements and it not overwriting elements. the data I'm storing: struct data { int number; char *name; }; typedef struct data data; # ifndef TYPE # define TYPE data* # define TYPE_SIZE sizeof(data*) # endif The tree struct: struct Node { TYPE val; struct Node *left; struct Node *rght; }; struct BSTree { struct Node *root; int cnt; }; The comparator for the data. int compare(TYPE left, TYPE right) { int left_len; int right_len; int shortest_string; /* find longest string */ left_len = strlen(left->name); right_len = strlen(right->name); if(right_len < left_len) { shortest_string = right_len; } else { shortest_string = left_len; } /* compare strings */ if(strncmp(left->name, right->name, shortest_string) > 1) { return 1; } else if(strncmp(left->name, right->name, shortest_string) < 1) { return -1; } else { /* strings are equal */ if(left->number > right->number) { return 1; } else if(left->number < right->number) { return -1; } else { return 0; } } } And the add method struct Node* _addNode(struct Node* cur, TYPE val) { if(cur == NULL) { /* no root has been made */ cur = _createNode(val); return cur; } else { int cmp; cmp = compare(cur->val, val); if(cmp == -1) { /* go left */ if(cur->left == NULL) { printf("adding on left node val %d\n", cur->val->number); cur->left = _createNode(val); } else { return _addNode(cur->left, val); } } else if(cmp >= 0) { /* go right */ if(cur->rght == NULL) { printf("adding on right node val %d\n", cur->val->number); cur->rght = _createNode(val); } else { return _addNode(cur->rght, val); } } return cur; } } void addBSTree(struct BSTree *tree, TYPE val) { tree->root = _addNode(tree->root, val); tree->cnt++; } The function to print the tree: void printTree(struct Node *cur) { if (cur == 0) { printf("\n"); } else { printf("("); printTree(cur->left); printf(" %s, %d ", cur->val->name, cur->val->number); printTree(cur->rght); printf(")\n"); } } Here's an example of some data that will overwrite previous elements: struct BSTree myTree; struct data myData1, myData2, myData3; myData1.number = 5; myData1.name = "rooty"; myData2.number = 1; myData2.name = "lefty"; myData3.number = 10; myData3.name = "righty"; initBSTree(&myTree); addBSTree(&myTree, &myData1); addBSTree(&myTree, &myData2); addBSTree(&myTree, &myData3); printTree(myTree.root); Which will print: (( righty, 10 ) lefty, 1 ) Finally here's some test data that will go in the exact same spot as the previous data, but this time no data is overwritten: struct BSTree myTree; struct data myData1, myData2, myData3; myData1.number = 5; myData1.name = "i"; myData2.number = 5; myData2.name = "h"; myData3.number = 5; myData3.name = "j"; initBSTree(&myTree); addBSTree(&myTree, &myData1); addBSTree(&myTree, &myData2); addBSTree(&myTree, &myData3); printTree(myTree.root); Which prints: (( j, 5 ) i, 5 ( h, 5 ) ) Does anyone know what might be going wrong? Sorry if this post was kind of long.

  • Boost::Asio : io_service.run() vs poll() or how do I integrate boost::asio in mainloop

    - by user300713
    Hi, I am currently trying to use boost::asio for some simple tcp networking for the first time, and I allready came across something I am not really sure how to deal with. As far as I understand io_service.run() method is basically a loop which runs until there is nothing more left to do, which means it will run until I release my little server object. Since I allready got some sort of mainloop set up, I would rather like tp update the networking loop manually from there just for the sake of simplicity, and I think io_service.poll() would do what I want, sort of like this: void myApplication::update() { myIoService.poll(); //do other stuff } This seems to work, but I am still wondering if there is a drawback from this method since that does not seem to be the common way to deal with boost::asios io services. Is this a valid approach or should I rather use io_service.run() in a non blocking extra thread?

  • Connecting to a SQL Server Compact Edition (.sdf) from an MFC application

    - by Hazerd
    Hey ! I'm building an MFC app in Visual Studio 2008 which classifies textures and I need some sort of lightweight database to hold the characteristics (just some doubles and strings) which can be: -carried around with the app on different computers; -be able to perform queries on it from the app (searches , updates ,inserts ,etc); Currently I'm looking into SQL compact edition because it was very easy to create from Visual Studio ( I also need only one table) but I having a hard time connecting and updating the db from C++. This is what I've found on msdn regarding C++ and SQLCE: public: void createSqlCeConnection(){ SqlCeConnection* myConnection = new SqlCeConnection(); myConnection->ConnectionString = "DataSource = blabla.sdf"; MessageBox::Show(String::Format( S"Connection State: {0}", __box(myConnection->State))); } Unfortunately my experience with .net apps is pretty limited. Hopefully you bright minds could tell me if I'm on the right path and what links and includes should I add for this to work with an C++ MFC projects. Thanks !

  • ASP.NET Web Page Not Available

    - by hahuang65
    It's pretty difficult to show code for ASP.NET here, so I will try my best to describe my problem. I have a FileUploadControl and a Button that calls a function when it's clicked. It seems that the Button function works when there is nothing chosen for my FileUploadControl. However, when there is something chosen in the FileUploadControl (I have selected a file to upload), there is a problem when I click the button. It completely does not matter what the function does (it could just be writing to a label, even when it has nothing to do with the FileUploadControl). The error I get is: This webpage is not available. The webpage at http://localhost:2134/UploadMedia/Default.aspx might be temporarily down or it may have moved permanently to a new web address. I have searched on Google, and people seem to have had problems with this, but different causes from me. They have said that their ASP.NET Development Server port is actually different from their port in the address bar. This is not the case for me. Also, another problem people have had is with Use Dynamic Ports. I have tried both true and false. I have also tried different ports, and I have always gotten the same error. This is really driving me crazy because it doesn't matter what the code in the buttonFunction is, it doesn't work as long as there is something in the FileUploadControl. If there is nothing, it seems to work fine. Here is the code for the ASP.NET Controls: <asp:FileUpload id="FileUploadControl" runat="server" /> <asp:Button runat="server" id="UploadButton" text="Upload" OnClick="uploadClicked" /> <br /><br /> <asp:Label runat="server" id="StatusLabel" text="Upload status: " /> And this is the code for the button function: protected void uploadClicked(object sender, EventArgs e) { if (FileUploadControl.HasFile) { string filename = Path.GetFileName(FileUploadControl.FileName); //Check if the entered username already exists in the database. String sqlDupStmt = "Select songPath from Songs where songPath ='" + Server.MapPath("~/Uploads/") + filename + "'"; SqlConnection sqlDupConn = new SqlConnection(@"Data Source = .\SQLEXPRESS; AttachDbFilename = |DataDirectory|\Database.mdf; Integrated Security = True; User Instance = True;"); SqlCommand sqlDupCmd = new SqlCommand(sqlDupStmt, sqlDupConn); sqlDupCmd.Connection.Open(); SqlDataReader sqlDupReader = sqlDupCmd.ExecuteReader(CommandBehavior.CloseConnection); if (sqlDupReader.Read()) { StatusLabel.Text = "Upload status: The file already exists."; sqlDupReader.Close(); } else { sqlDupReader.Close(); //See "How To Use DPAPI (Machine Store) from ASP.NET" for information about securely storing connection strings. String sqlStmt = "Insert into Songs values (@songpath);"; SqlConnection sqlConn = new SqlConnection(@"Data Source = .\SQLEXPRESS; AttachDbFilename = |DataDirectory|\Database.mdf; Integrated Security = True; User Instance = True; uid=sa; pwd=password;"); SqlCommand cmd = new SqlCommand(sqlStmt, sqlConn); SqlParameter sqlParam = null; //Usage of Sql parameters also helps avoid SQL Injection attacks. sqlParam = cmd.Parameters.Add("@userName", SqlDbType.VarChar, 150); sqlParam.Value = Server.MapPath("~/Uploads/") + filename; //Attempt to add the song to the database. try { sqlConn.Open(); cmd.ExecuteNonQuery(); FileUploadControl.SaveAs(Server.MapPath("~/Uploads/") + filename); songList.Items.Add(filename); StatusLabel.Text = "Upload status: File uploaded!"; } catch (Exception ex) { StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message; } finally { sqlConn.Close(); } } } } But this buttonfunction provides the same results: protected void uploadClicked(object sender, EventArgs e) { StatusLabel.Text = "FooBar"; } Has anyone had this problem before, or might know what the cause is? Thanks!

  • Are stack based arrays possible in C#?

    - by Bob
    Let's say, hypothetically (read: I don't think I actually need this, but I am curious as the idea popped into my head), one wanted an array of memory set aside locally on the stack, not on the heap. For instance, something like this: private void someFunction() { int[20] stackArray; //C style; I know the size and it's set in stone } I'm guessing the answer is no. All I've been able to find is heap based arrays. If someone were to need this, would there be any workarounds? Is there any way to set aside a certain amount of sequential memory in a "value type" way? Or are structs with named parameters the only way (like the way the Matrix struct in XNA has 16 named parameters (M11-M44))?

  • ASP.Net GridView GridViewDeleteEventArgs.Keys empty

    - by the berserker
    I have following Gridview: <asp:GridView ID="GridView1" runat="server" CssClass="table" DataKeyNames="groupId" DataSource="<%# dsUserGroupsSelected %>" DataMember="Group" etc....> and after firing RowDeleting event handler: protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) e.Keys is empty. Moreover, in runtime if I check dsUserGroupsSelected.Group.PrimaryKey it is poulated with: {System.Data.DataColumn[1]} [0]: {groupId} so it's really odd to me. Am I missing something? I have this kind of a workaround: int groupId = (int)GridView1.DataKeys[e.RowIndex].Value; which will work just fine, but I just can't get it why e.Keys (and e.Values) would be empty!? Any ideas?

  • Int or NSInteger as object for method argument. Objective-C

I'm having some trouble passing a number as an argument for a method: -(void) meth2:(int)next_int; And to call that method i need this: int next_int = 1; [self performSelectorOnMainThread:@selector(meth2:) withObject:next_int waitUntilDone:NO]; //update next_int and call meth2 again at this point i get a "pointer from integer without a cast" error, and would happen the same with a NSInteger. A NSNumber is not useful because it's immutable and i need to change the value constantly. Any Idea how can i do this? Thanks.
