    - by objectsbinding
    Hi All I have the following class public class CountrySpecificPIIEntity { public string Country { get; set; } public string CreditCardType { get; set; } public String Api { get; set; } public List<String> FilterList { get; set; } } I am trying to use a linq to XMl query to create a list of instances of type CountrySpecificPIIEntity.

  • WCF: Configuring Known Types

    - by jerbersoft
    I want to know as to how to configure known types in WCF. For example, I have a Person class and an Employee class. The Employee class is a sublass of the Person class. Both class are marked with a [DataContract] attribute. I dont want to hardcode the known type of a class, like putting a [ServiceKnownType(typeof(Employee))] at the Person class so that WCF will know that Employee is a subclass of Person. Now, I added to the host's App.config the following XML configuration: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.runtime.serialization> <dataContractSerializer> <declaredTypes> <add type="Person, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"> <knownType type="Employee, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral, PublicKeyToken=null" /> </add> </declaredTypes> </dataContractSerializer> </system.runtime.serialization> <system.serviceModel> ....... </system.serviceModel> </configuration> I compiled it, run the host, added a service reference at the client and added some code and run the client. But an error occured: The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://www.herbertsabanal.net:person. The InnerException message was 'Error in line 1 position 247. Element 'http://www.herbertsabanal.net:person' contains data of the 'http://www.herbertsabanal.net/Data:Employee' data contract. The deserializer has no knowledge of any type that maps to this contract. Add the type corresponding to 'Employee' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details. Below are the data contracts: [DataContract(Namespace="http://www.herbertsabanal.net/Data", Name="Person")] class Person { string _name; int _age; [DataMember(Name="Name", Order=0)] public string Name { get { return _name; } set { _name = value; } } [DataMember(Name="Age", Order=1)] public int Age { get { return _age; } set { _age = value; } } } [DataContract(Namespace="http://www.herbertsabanal.net/Data", Name="Employee")] class Employee : Person { string _id; [DataMember] public string ID { get { return _id; } set { _id = value; } } } Btw, I didn't use class libraries (WCF class libraries or non-WCF class libraries) for my service. I just plain coded it in the host project. I guess there must be a problem at the config file (please see config file above). Or I must be missing something. Any help would be pretty much appreciated.

  • ListView with button and check mark?

    - by jgelderloos
    So I have looked through a lot of other answers but have not been able to get my app to work how I want it. I basically want the list view that has the text and check mark to the right, but then an addition button to the left. Right now my list view shows up but the check image is never changed. Selector: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true" android:drawable="@drawable/accept_on" /> <item android:drawable="@drawable/accept" /> </selector> Row xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:background="#EEE"> <ImageButton android:id="@+id/goToMapButton" android:src="@drawable/go_to_map" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="left" /> <TextView android:id="@+id/itemName" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_vertical" android:textColor="#000000" android:layout_marginTop="5dp" android:layout_marginBottom="5dp" android:layout_weight="1" /> <Button android:id="@+id/checkButton" android:background="@drawable/item_selector" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="right" /> </LinearLayout> MapAdapter: import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.ImageButton; import android.widget.LinearLayout; import android.widget.TextView; public class MapAdapter extends ArrayAdapter<String>{ Context context; int layoutResourceId; String data[] = null; LayoutInflater inflater; LinearLayout layout; public MapAdapter(Context context, int layoutResourceId, String[] data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; inflater = LayoutInflater.from(context); } @Override public String getItem(int position) { return data[position]; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = new ViewHolder(); if(convertView == null) { convertView = inflater.inflate(R.layout.map_item_row, null); layout = (LinearLayout)convertView.findViewById(R.id.layout); holder.map = (ImageButton)convertView.findViewById(R.id.goToMapButton); holder.name = (TextView)convertView.findViewById(R.id.itemName); //holder.check = (Button)convertView.findViewById(R.id.checkButton); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } layout.setBackgroundColor(0x00000004); holder.name.setText(getItem(position)); return convertView; } static class ViewHolder { ImageButton map; TextView name; Button check; } }

  • Linq to SQL NullReferenceException's: A random needle in a haystack!

    - by Shane
    I'm getting NullReferenceExeceptions at seemly random times in my application and can't track down what could be causing the error. I'll do my best to describe the scenario and setup. Any and all suggestions greatly appreciated! C# .net 3.5 Forms Application, but I use the WebFormRouting library built by Phil Haack (http://haacked.com/archive/2008/03/11/using-routing-with-webforms.aspx) to leverage the Routing libraries of .net (usually used in conjunction with MVC) - intead of using url rewriting for my urls. My database has 60 tables. All Normalized. It's just a massive application. (SQL server 2008) All queries are built with Linq to SQL in code (no SP's). Each time a new instance of my data context is created. I use only one data context with all relationships defined in 4 relationship diagrams in SQL Server. the data context gets created a lot. I let the closing of the data context be handled automatically. I've heard arguments both sides about whether you should leave to be closed automatically or do it yourself. In this case I do it myself. It doesnt seem to matter if I'm creating a lot of instances of the data context or just one. For example, I've got a vote-up button. with the following code, and it errors probably 1 in 10-20 times. protected void VoteUpLinkButton_Click(object sender, EventArgs e) { DatabaseDataContext db = new DatabaseDataContext(); StoryVote storyVote = new StoryVote(); storyVote.StoryId = storyId; storyVote.UserId = Utility.GetUserId(Context); storyVote.IPAddress = Utility.GetUserIPAddress(); storyVote.CreatedDate = DateTime.Now; storyVote.IsDeleted = false; db.StoryVotes.InsertOnSubmit(storyVote); db.SubmitChanges(); // If this story is not yet published, check to see if we should publish it. Make sure that // it is already approved. if (story.PublishedDate == null && story.ApprovedDate != null) { Utility.MakeUpcommingNewsPopular(storyId); } // Refresh our page. Response.Redirect("/news/" + category.UniqueName + "/" + RouteData.Values["year"].ToString() + "/" + RouteData.Values["month"].ToString() + "/" + RouteData.Values["day"].ToString() + "/" + RouteData.Values["uniquename"].ToString()); } The last thing I tried was the "Auto Close" flag setting on SQL Server. This was set to true and I changed to false. Doesnt seem to have done the trick although has had a good overall effect. Here's a detailed that wasnt caught. I also get slighly different errors when caught by my try/catch's. System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Util.StringUtil.GetStringHashCode(String s) at System.Web.UI.ClientScriptManager.EnsureEventValidationFieldLoaded() at System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) at System.Web.UI.WebControls.TextBox.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.forms_news_detail_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) HELP!!!

  • OSX: How to get a volume name (or bsd name) from a IOUSBDeviceInterface or location id

    - by LG
    Hi, I'm trying to write an app that associates a particular USB string descriptor (of a USB mass storage device) with its volume or bsd name. So the code goes through all the connected USB devices, gets the string descriptors and extracts information from one of them. I would like to get the volume name of those USB devices. I can't find the right API to do that. I have tried to do that: DASessionRef session = DASessionCreate(kCFAllocatorDefault); DADiskRef disk_ref = DADiskCreateFromIOMedia(kCFAllocatorDefault, session, usb_device_ref); const char* name = DADiskGetBSDName(disk_ref); But the DADiskCreateFromIOMedia function returned nil, I assume the usb_device_ref that I passed was not compatible with the io_service_t that the function is expecting. So how can I get the volume name of a USB device? Could I use the location id to do that? Thanks for reading. -L FOO_Result result = FOO_SUCCESS; mach_port_t master_port; kern_return_t k_result; io_iterator_t iterator = 0; io_service_t usb_device_ref; CFMutableDictionaryRef matching_dictionary = NULL; // first create a master_port if (FOO_FAILED(k_result = IOMasterPort(MACH_PORT_NULL, &master_port))) { fprintf(stderr, "could not create master port, err = %d\n", k_result); goto cleanup; } if ((matching_dictionary = IOServiceMatching(kIOUSBDeviceClassName)) == NULL) { fprintf(stderr, "could not create matching dictionary, err = %d\n", k_result); goto cleanup; } if (FOO_FAILED(k_result = IOServiceGetMatchingServices(master_port, matching_dictionary, &iterator))) { fprintf(stderr, "could not find any matching services, err = %d\n", k_result); goto cleanup; } while (usb_device_ref = IOIteratorNext(iterator)) { IOReturn err; IOCFPlugInInterface **iodev; // requires <IOKit/IOCFPlugIn.h> IOUSBDeviceInterface **dev; SInt32 score; err = IOCreatePlugInInterfaceForService(usb_device_ref, kIOUSBDeviceUserClientTypeID, kIOCFPlugInInterfaceID, &iodev, &score); if (err || !iodev) { printf("dealWithDevice: unable to create plugin. ret = %08x, iodev = %p\n", err, iodev); return; } err = (*iodev)->QueryInterface(iodev, CFUUIDGetUUIDBytes(kIOUSBDeviceInterfaceID), (LPVOID*)&dev); (*iodev)->Release(iodev); // done with this FOO_String string_value; UInt8 string_index = 0x1; FOO_Result result = FOO_SUCCESS; CFStringRef device_name_as_cf_string; do { if (FOO_SUCCEEDED(result = FOO_GetStringDescriptor(dev, string_index, 0, string_value))) { printf("String at index %i is %s\n", string_index, string_value.GetChars()); // extract the command code if it is the FOO string if (string_value.CompareN("FOO:", 4) == 0) { FOO_Byte code = 0; FOO_HexToByte(string_value.GetChars() + 4, code); // Get other relevant information from the device io_name_t device_name; UInt32 location_id = 0; // Get the USB device's name. err = IORegistryEntryGetName(usb_device_ref, device_name); device_name_as_cf_string = CFStringCreateWithCString(kCFAllocatorDefault, device_name, kCFStringEncodingASCII); err = (*dev)->GetLocationID(dev, &location_id); // TODO: get volume or BSD name // add the device to the list break; } } string_index++; } while (FOO_SUCCEEDED(result)); err = (*dev)->USBDeviceClose(dev); if (err) { printf("dealWithDevice: error closing device - %08x\n", err); (*dev)->Release(dev); return; } err = (*dev)->Release(dev); if (err) { printf("dealWithDevice: error releasing device - %08x\n", err); return; } IOObjectRelease(usb_device_ref); // no longer need this reference }

  • Padding error - when using AES Encryption in Java and Decryption in C

  • Windows Phone 7 Connect to SharePoint via SOAP

    - by Mitchell Skurnik
    I am making my second application for the Windows 7 Phone Series platform and I cannot seem to connect to a SharePoint server using https. 99% of the following is not my code. I have borrowed it from http://blog.daisley-harrison.com/blog/post/Practical-Silverlight-and-SharePoint-Integration-Part-Two.aspx untill I can further understand how SOAP works in W7P Series. I know that I need some way of sending credentials over but the win 7 API does not seem to let you. ServiceReferences.ClientConfig <?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="ViewsSoap" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" transferMode="Buffered"> <security mode="TransportCredentialOnly"/> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="https://my.secureconnection.com/_vti_bin/views.asmx" binding="basicHttpBinding" bindingConfiguration="ViewsSoap" contract="SharePointListService.ViewsSoap" name="ViewsSoap" /> </client> </system.serviceModel> </configuration> This is my maincode page: public partial class MainPage : PhoneApplicationPage { public MainPage() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape; try { Uri serviceUri = new Uri("https://my.secureconnection.com" + SERVICE_LISTS_URL); BasicHttpBinding binding; if (serviceUri.Scheme == "https") { binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport); } else { binding = new BasicHttpBinding(BasicHttpSecurityMode.None); } EndpointAddress endpoint = new EndpointAddress(serviceUri); ListsSoapClient listSoapClient = new ListsSoapClient(binding, endpoint); NetworkCredential creds = new NetworkCredential("administrator", "iSynergy1", "server001"); //listSoapClient.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Identification; //listSoapClient.ClientCredentials.Windows.ClientCredential = creds; listSoapClient.GetListCollectionCompleted += new EventHandler<GetListCollectionCompletedEventArgs>(listSoapClient_GetListCollectionCompleted); listSoapClient.GetListCollectionAsync(); } catch (Exception exception) { handleException("Failed to get list collection", exception); } } #region ShowExceptionDetail Property public static readonly DependencyProperty ShowExceptionDetailDependencyProperty = DependencyProperty.Register("ShowExceptionDetail",typeof(bool),typeof(Page),new PropertyMetadata(true)); public bool ShowExceptionDetail { get { return (bool)GetValue(ShowExceptionDetailDependencyProperty); } set { SetValue(ShowExceptionDetailDependencyProperty, value); } } #endregion private void handleException(string context, Exception exception) { this.Dispatcher.BeginInvoke(delegate() { bool showExceptionDetail = this.ShowExceptionDetail; string message = ""; Exception next = exception; do { if (message.Length > 0) { message += ";" + Environment.NewLine; } if (next.Message == null || next.Message.Length == 0) { message += next.GetType().FullName; } else { message += next.Message; } if (showExceptionDetail) { if (next.Data.Count > 0) { bool first = true; message += " {"; foreach (string key in next.Data.Keys) { if (first) { first = false; } else { message += ", "; } message += key + "=\"" + next.Data[key] + "\""; } message += "}"; } if (next.InnerException != next) { next = next.InnerException; continue; } } next = null; } while (next != null); MessageBox.Show(message, context, MessageBoxButton.OK); }); } private const string SERVICE_LISTS_URL = "/_vti_bin/lists.asmx"; void listSoapClient_GetListCollectionCompleted(object sender, GetListCollectionCompletedEventArgs e) { try { myList.Text = e.Result.ToString(); } catch (Exception exception) { handleException("Failed to get list collection", exception); } } } When I run this and it gets to the "ListsSoapClient" part, it breaks. If you dig down into the error output it says access is denied. I have tried various methods of sending credentials but none seem to work. "ClientCredentials.Windows" is not supported and ClientCredentials.UsersName.Username is read only.

  • HttpParsing for hypertext

    - by Nani
    I am in process of getting all hierarchical links from a given link and validating them; This is the code I wrote. But I am not feeling it as efficient. Reasons are: 1.For the non unique links which open same page, code is getting sub-links again and again 2.Is the code getting all links? 3.Is it making valid URLs from the sub-links it derived? 4.May be some other reasons about which I have no idea. Please suggest me how to make this piece of code efficient . Thank you. class Program { public static ArrayList sublink = new ArrayList(); public static ArrayList subtitle = new ArrayList(); public static int ini = 0, len_o, len_n, counter = 0; static void Main(string[] args) { // Address of URL string URL = "http://www.techonthenet.com/"; sublink.Add(URL); l: len_o = sublink.Count; len_o); Console.WriteLine("-------------Level:" + counter++); for (int i = ini; i < len_o; i++) test(sublink[i].ToString()); len_n = sublink.Count; if (len_o < len_n) { ini = len_o; goto l; } Console.ReadKey(); } //method to get the sub-links public static void test(string URL) { try { // Get HTML data WebClient client = new WebClient(); Stream data = client.OpenRead(URL); StreamReader reader = new StreamReader(data); string str = "", htmldata = "", temp; int n1, n2; str = reader.ReadLine(); while (str != null) { htmldata += str; str = reader.ReadLine(); } data.Close(); for (int i = 0; i < htmldata.Length - 5; i++) { if (htmldata.Substring(i, 5) == "href=") { n1 = htmldata.Substring(i + 6, htmldata.Length - (i + 6)).IndexOf("\""); temp = htmldata.Substring(i + 6, n1); if (temp.Length > 4 && temp.Substring(0, 4) != "http") { if(temp.Substring(0,1)!="/") temp=URL.Substring(0,URL.IndexOf(".com/")+5)+temp; else temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp.Remove(0,1); } if (temp.Length < 4) temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp; sublink.Add(temp); n2 = htmldata.Substring(i + n1 + 1, htmldata.Length - (i + n1 + 1)).IndexOf("<"); subtitle.Add(htmldata.Substring(i + 6 + n1 + 2, n2 - 7)); i += temp.Length + htmldata.Substring(i + 6 + n1 + 2, n2 - 7).Length; } } for (int i = len_n; i < sublink.Count; i++) Console.WriteLine(i + "--> " + sublink[i]); } catch (WebException exp) { Console.WriteLine("URL Could not be Resolved" + URL); Console.WriteLine(exp.Message, "Exception"); } } }

  • Why is my code returning a Null Object Refrence error when using WatIn?

    - by Fuzz Evans
    I keep getting a Null Object Refrence Error, but can't tell why. I have a CSV file that contains 100 urls. The file is read into an array called "lines". public partial class Form1 : System.Windows.Forms.Form { string[] lines; public Form1() ... private void ReadLinksIntoMemory() { //this reads the chosen csv file into our "lines" array //and splits on comma's and new lines to create new objects within the array using (StreamReader sr = new StreamReader(@"C:\temp.csv")) { //reads everything in our csv into 1 long line string fileContents = sr.ReadToEnd(); //splits the 1 long line read in into multiple objects of the lines array lines = fileContents.Split(new string[] { ",", Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); sr.Dispose(); } } The next part is where I get the null object error. When I try to use WatIn to go to the first item in the lines array it says I'm referencing a null object. private void GoToEditLinks() { for (int i = 0; i < lines.Length; i++) { //go to each link sequentially myIE.GoTo(lines[i].ToString()); //sleep so we can make sure the page loads System.Threading.Thread.Sleep(5000); } } When I debug the code it says that the GoTo request calls lines which is null. It seems like I need to declare the array, but don't I need to tell it an exact size to do that? Example: lines = new string[10] I thought I could use the lines.Length to tell it how big to make the array but that didn't work. What is weird to me is I can use the following code without problem: //returns the accurate number of urls that were in the CSV we read in earlier txtbx1.text = lines.Length; //or //this returns the last entry in the csv, as well as the last entry in the array TextBox2.Text = lines[lines.Length - 1]; I am confused why the array clearly has items in it, they can be called to fill a text box, but when I try to call them in my for loop it says its a null reference? UPDATE: By placing my cursor on both calls to lines and pressing f12 I find they both go to the same instance. The thought next is that I am not calling ReadLinksIntoMemory in time, below is my code: private void button1_Click(object sender, EventArgs e) { button1.Enabled = false; ReadLinksIntoMemory(); GoToEditLinks(); button1.Enabled = true; } Unless I'm mistaken the code says that the ReadLinksIntoMemory method must complete before GoToEditLinks can be called? If ReadLinksIntoMemory didn't finish in time I shouldn't be able to fill my text boxes with the lines array length and/or last entry. UPDATE: Stepping into the method GoToEditLinks() I see that lines is null before it calls: myIE.GoTo(lines[i]); but when it hits the goto command the value changes from null to the url it is suppose to go to, but at that same time it gives me the null object error? UPDATE: I added a IsNullOrEmpty check method and lines array passes it without any issue. I'm beginning to think it is an issue with WatIn and the myIE.GoTo command. I think this is the stack trace/call stack? Program.exe!Program.Form1.GoToEditLinks() Line 284 C# Program.exe!Program.Form1.button1_Click(object sender, System.EventArgs e) Line 191 + 0x8 bytes C# [External Code] Program.exe!Program.Program.Main() Line 18 + 0x1d bytes C# [External Code]

  • WinMo > ASMX WebException - how to get details?

    - by eidylon
    Okay, we've got an application which consists of a website hosting several ASMX webservices, and a handheld application running on WinMo 6.1 which calls the webservices. Been developing in the office, everything works perfect. Now we've gone to install it at the client's and we got all the servers set up and the handhelds installed. However the handhelds are now no longer able to connect to the webservice. I added in extra code in my error handler to specifically trap WebException exceptions and handle them differently in the logging to put out extra information (.Status and .Response). I am getting out the status, which is returning a [7], or ProtocolError. However when I try to read out the ResponseStream (using WebException.Response.GetResponseStream), it is returning a stream with CanRead set to False, and I thus am unable to get any further details of what is going wrong. So I guess there are two things I am asking for help with... a) Any help with trying to get more information out of the WebException? b) What could be causing a ProtocolError exception? Things get extra complicated by the fact that the client has a full-blown log-in-enabled proxy setup going on-site. This was stopping all access to the website initially, even from a browser. So we entered in the login details in the network connection for HTTP on the WinMo device. Now it can get to websites fine. In fact, I can even pull up the webservice fine and call the methods from the browser (PocketIE). So I know the device is able to see the webservices okay via HTTP. But when trying to call them from the .NET app, it throws ProtocolError [7]. Here is my code which is logging the exception and failing to read out the Response from the WebException. Public Sub LogEx(ByVal ex As Exception) Try Dim fn As String = Path.Combine(ini.CorePath, "error.log") Dim t = File.AppendText(fn) t.AutoFlush = True t.WriteLine(<s>===== <%= Format(GetDateTime(), "MM/dd/yyyy HH:mm:ss") %> =====<%= vbCrLf %><%= ex.Message %></s>.Value) t.WriteLine() t.WriteLine(ex.ToString) t.WriteLine() If TypeOf ex Is WebException Then With CType(ex, WebException) t.WriteLine("STATUS: " & .Status.ToString & " (" & Val(.Status) & ")") t.WriteLine("RESPONSE:" & vbCrLf & StreamToString(.Response.GetResponseStream())) End With End If t.WriteLine("=".Repeat(50)) t.WriteLine() t.Close() Catch ix As Exception : Alert(ix) : End Try End Sub Private Function StreamToString(ByVal s As IO.Stream) As String If s Is Nothing Then Return "No response found." // THIS IS THE CASE BEING EXECUTED If Not s.CanRead Then Return "Unreadable response found." Dim rv As String = String.Empty, bytes As Long, buffer(4096) As Byte Using mem As New MemoryStream() Do While True bytes = s.Read(buffer, 0, buffer.Length) mem.Write(buffer, 0, bytes) If bytes = 0 Then Exit Do Loop mem.Position = 0 ReDim buffer(mem.Length) mem.Read(buffer, 0, mem.Length) mem.Seek(0, SeekOrigin.Begin) rv = New StreamReader(mem).ReadToEnd() mem.Close() End Using Return rv.NullOf("Empty response found.") End Function Thanks in advance!

  • DoubleBuffering in Java

    - by DDP
    Hello there, I'm having some trouble implementing DoubleBuffer into my program. Before you faint from the wall of text, you should know that a lot of it is there just in case you need to know. The actual place where I think I'm having problems is in one method. I've recently looked up a tutorial on the gpwiki about double buffering, and decided to try and implement the code they had into the code I have that I'm trying to implement doublebuffer in. I get the following error: "java.lang.IllegalStateException: Component must have a valid peer". I don't know if it makes any difference if you know it or not, but the following is the code with the main method. This is just a Frame that displays the ChronosDisplay class inside it. I omitted irrelevant code with "..." public class CDM extends JFrame { public CDM(String str) { super("CD:M - "+str); try { ... ChronosDisplay theGame = new ChronosDisplay(str); ((Component)theGame).setFocusable(true); add(theGame); } catch(Exception e) { System.out.println("CDM ERROR: " +e); } } public static void main( String args[] ) { CDM run = new CDM("DP_Mini"); } } Here is the code where I think the problem resides (I think the problem is in the paint() method). This class is displayed in the CDM class public class ChronosDisplay extends Canvas implements Runnable { String mapName; public ChronosDisplay (String str) { mapName = str; new Thread(this).start(); setVisible(true); createBufferStrategy(2); } public void paint( Graphics window ) { BufferStrategy b = getBufferStrategy(); Graphics g = null; window.setColor(Color.white); try { g = b.getDrawGraphics(); paintMap(g); paintUnits(g); paintBullets(g); } finally { g.dispose(); } b.show(); Toolkit.getDefaultToolkit().sync(); } public void paintMap( Graphics window ) { TowerMap m = new TowerMap(); try { m = new TowerMap(mapName); for(int x=0; x<m.getRows()*50; x+=50) { for(int y = 0; y<m.getCols()*50; y+=50) { int tileType = m.getLocation(x/50,y/50); Image img; if(tileType == 0) { Tile0 t = new Tile0(x,y); t.draw(window); } ...// More similar if statements for other integers } catch(Exception e) ... } ...// Additional methods not shown here public void run() { try { while(true) { Thread.currentThread().sleep(20); repaint(); } } catch(Exception e) ... } } If you're curious (I doubt it matters), the draw() method in the Tile0 class is: public void draw( Graphics window ) { window.drawImage(img,getX(),getY(),50,50,null); } Any pointers, tips, or solutions are greatly appreciated. Thanks for your time! :D

  • Compress file to bytes for uploading to SQL Server

  • JPA IndirectSet changes not reflected in Spring frontend

    - by Jon
    I'm having an issue with Spring JPA and IndirectSets. I have two entities, Parent and Child, defined below. I have a Spring form in which I'm trying to create a new Child and link it to an existing Parent, then have everything reflected in the database and in the web interface. What's happening is that it gets put into the database, but the UI doesn't seem to agree. The two entities that are linked to each other in a OneToMany relationship like so: @Entity @Table(name = "parent", catalog = "myschema", uniqueConstraints = @UniqueConstraint(columnNames = "ChildLinkID")) public class Parent { private Integer id; private String childLinkID; private Set<Child> children = new HashSet<Child>(0); @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @Column(name = "ChildLinkID", unique = true, nullable = false, length = 6) public String getChildLinkID() { return this.childLinkID; } public void setChildLinkID(String childLinkID) { this.childLinkID = childLinkID; } @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "parent") public Set<Child> getChildren() { return this.children; } public void setChildren(Set<Child> children) { this.children = children; } } @Entity @Table(name = "child", catalog = "myschema") public class Child extends private Integer id; private Parent parent; @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "ChildLinkID", referencedColumnName = "ChildLinkID", nullable = false) public Parent getParent() { return this.parent; } public void setParent(Parent parent) { this.parent = parent; } } And of course, assorted simple properties on each of them. Now, the problem is that when I edit those simple properties from my Spring interface, everything works beautifully. I can persist new entities of these types and they'll appear when using the JPATemplate to do a find on, say, all Parents (getJpaTemplate().find("select p from Parent p")) or on individual entities by ID or another property. The problem I'm running into is that now, I'm trying to create a new Child linked to an existing Parent through a link from the Parent's page. Here's the important bits of the Controller (note that I've placed the JPA foo in the controller here to make it clearer; the actual JpaDaoSupport is actually in another class, appropriately tiered): protected Object formBackingObject(HttpServletRequest request) throws Exception { String parentArg = request.getParameter("parent"); int parentId = Integer.parseInt(parentArg); Parent parent = getJpaTemplate().find(Parent.class, parentId); Child child = new Child(); child.setParent(parent); NewChildCommand command = new NewChildCommand(); command.setChild(child); return command; } protected ModelAndView onSubmit(Object cmd) throws Exception { NewChildCommand command = (NewChildCommand)cmd; Child child = command.getChild(); child.getParent().getChildren().add(child); getJpaTemplate().merge(child); return new ModelAndView(new RedirectView(getSuccessView())); } Like I said, I can run through the form and fill in the new values for the Child -- the Parent's details aren't even displayed. When it gets back to the controller, it goes through and saves it to the underlying database, but the interface never reflects it. Once I restart the app, it's all there and populated appropriately. What can I do to clear this up? I've tried to call extra merges, tried refreshes (which gave a transaction exception), everything short of just writing my own database access code. I've made sure that every class has an appropriate equals() and hashCode(), have full JPA debugging on to see that it's making appropriate SQL calls (it doesn't seem to make any new calls to the Child table) and stepped through in the debugger (it's all in IndirectSets, as expected, and between saving and displaying the Parent the object takes on a new memory address). What's my next step?

    Hello everyone! I have a question regarding Wicket's Datatable. I am currently using DataTable to display a few columns of data. My table is set up as follows: DataTable<Column> dataTable = new DataTable<Column>("columnsTable", columns, provider, maxRowsPerPage) { @Override protected Item<Column> newRowItem(String id, int index, IModel<Column> model) { return new OddEvenItem<Column>(id, index, model); } }; The columns look like so: columns[0] = new PropertyColumn<Column>(new Model<String>("Description"), "description", "description"); columns[1] = new PropertyColumn<Column>(new Model<String>("Logic"), "columnLogic"); columns[2] = new PropertyColumn<Column>(new Model<String>("Type"), "dataType", "dataType"); Here is my column data provider: public class ColumnSortableDataProvider extends SortableDataProvider<Column> { private static final long serialVersionUID = 1L; private List<Column> list = null; public ColumnSortableDataProvider(Table table) { this.list = Arrays.asList(table.getColumns().toArray(new Column[0])); } public ColumnSortableDataProvider(List<Column> list) { this.list = list; } @Override public Iterator<? extends Column> iterator(int first, int count) { /* first - first row of data count - minimum number of elements to retrieve So this method returns an iterator capable of iterating over {first, first+count} items */ Iterator<Column> iterator = null; try { if(getSort() != null) { Collections.sort(list, new Comparator<Column>() { private static final long serialVersionUID = 1L; @Override public int compare(Column c1, Column c2) { int result=1; PropertyModel<Comparable> model1= new PropertyModel<Comparable>(c1, getSort().getProperty()); PropertyModel<Comparable> model2= new PropertyModel<Comparable>(c2, getSort().getProperty()); if(model1.getObject() == null && model2.getObject() == null) result = 0; else if(model1.getObject() == null) result = 1; else if(model2.getObject() == null) result = -1; else result = ((Comparable)model1.getObject()).compareTo(model2.getObject()); result = getSort().isAscending() ? result : -result; return result; } }); } if (list.size() > (first+count)) iterator = list.subList(first, first+count).iterator(); else iterator = list.iterator(); } catch (Exception e) { e.printStackTrace(); } return iterator; } Sorting by clicking a column works perfectly, but I would like the table to initially be sorted, by default, by the Description column. I am at a loss to do this. If you need to see some other code, please let me know. Thank you in advance!!! - D

  • Marshal a C# struct to C++ VARIANT

    - by jortan
    To start with, I'm not very familiar with the COM-technology, this is the first time I'm working with it so bear with me. I'm trying to call a COM-object function from C#. This is the interface in the idl-file: [id(6), helpstring("vConnectInfo=ConnectInfoType")] HRESULT ConnectTarget([in,out] VARIANT* vConnectInfo); This is the interop interface I got after running tlbimp: void ConnectTarget(ref object vConnectInfo); The c++ code in COM object for the target function: STDMETHODIMP PCommunication::ConnectTarget(VARIANT* vConnectInfo) { if (!((vConnectInfo->vt & VT_ARRAY) && (vConnectInfo->vt & VT_BYREF))) { return E_INVALIDARG; } ConnectInfoType *pConnectInfo = (ConnectInfoType *)((*vConnectInfo->pparray)->pvData); ... } This COM-object is running in another process, it is not in a dll. I can add that the COM object is also used from another program written in C++. In that case there is no problem because in C++ a VARIANT is created and pparray-pvData is set to the connInfo data-structure and then the COM-object is called with the VARIANT as parameter. In C#, as I understand, my struct should be marshalled as a VARIANT automatically. These are two methods I've been using (or actually I've tried a lot more...) to call this method from C#: private void method1_Click(object sender, EventArgs e) { pcom.PCom PCom = new pcom.PCom(); pcom.IGeneralManagementServices mgmt = (pcom.IGeneralManagementServices)PCom; m_ci = new ConnectInfoType(); fillConnInfo(ref m_ci); mgmt.ConnectTarget(m_ci); } In the above case the struct gets marshalled as VT_UNKNOWN. This is a simple case and works if the parameter is not a struct (eg. works for int). private void method4_Click(object sender, EventArgs e) { ConnectInfoType ci = new ConnectInfoType(); fillConnInfo(ref ci); pcom PCom = new pcom.PCom(); pcom.IGeneralManagementServices mgmt = (pcom.IGeneralManagementServices)PCom; ParameterModifier[] pms = new ParameterModifier[1]; ParameterModifier pm = new ParameterModifier(1); pm[0] = true; pms[0] = pm; object[] param = new object[1]; param[0] = ci; object[] args = new object[1]; args[0] = param; mgmt.GetType().InvokeMember("ConnectTarget", BindingFlags.InvokeMethod, null, mgmt, args, pms, null, null); } In this case it gets marshalled as VT_ARRAY | VT_BYREF | VT_VARIANT. The problem is that when debugging the "target-function" ConnectTarget I cannot find the data I send in the SAFEARRAY-struct (or in any other place in memory either) What do I do with a VT_VARIANT? Any ideas on how to get my struct-data? Update: The ConnectInfoType struct: [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public class ConnectInfoType { public short network; public short nodeNumber; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 51)] public string connTargPassWord; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)] public string sConnectId; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 16)] public string sConnectPassword; public EnuConnectType eConnectType; public int hConnectHandle; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)] public string sAccessPassword; }; And the corresponding struct in c++: typedef struct ConnectInfoType { short network; short nodeNumber; char connTargPassWord[51]; char sConnectId[8]; char sConnectPassword[16]; EnuConnectType eConnectType; int hConnectHandle; char sAccessPassword[8]; } ConnectInfoType;

(as I know we can`t create thread inside bean, but could we call bean from different threads? ). If No, what is the bast practice for organize such request pool? Thanks. << Answer: I am using DI (EJB 3.1) soo i do not need any look up here. (application packed in ear and both modules in it (web module and ejb), it works perfect for me). But I can use it only in managed classes. So.. 2.Can I use manual look up in Tread ? Could I use Bean that extends ThreadPoolExecutor and calling another bean that implements Runnable ? Or it is not allowed ?
