  • Does Google App Engine allow creation of files and folders on the server ?

    - by Frank
    I know Google App Engine offers free space, but I wonder if it's for storing data in it's database only or does it also allow me to create files and directories on the server side to store my data ? For instance can I use the following method to save file ? public static void saveFile(String File_Path,StringBuffer Str_Buf,boolean Append) { FileOutputStream fos=null; BufferedOutputStream bos=null; try { fos=new FileOutputStream(File_Path,Append); bos=new BufferedOutputStream(fos); for (int j=0;j<Str_Buf.length();j++) bos.write(Str_Buf.charAt(j)); } catch (Exception e) { e.printStackTrace(); } finally { try { if (bos!=null) { bos.close(); bos=null; } if (fos!=null) { fos.close(); fos=null; } } catch (Exception ex) { ex.printStackTrace(); } } } Frank

  • Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

    - by SilverHorse
    I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.

  • WCF: what timeout property to use?

    - by Tom234
    I have a piece of code like so NetTcpBinding binding = new NetTcpBinding(SecurityMode.Transport); binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows; binding.CloseTimeout = new TimeSpan(0, 0, 1); binding.OpenTimeout = new TimeSpan(0, 0, 1); binding.SendTimeout = new TimeSpan(0, 0, 1); binding.ReceiveTimeout = new TimeSpan(0, 0, 1); EndpointAddress endPoint = new EndpointAddress(new Uri(clientPath)); DuplexChannelFactory<Iservice> channel = new DuplexChannelFactory<Iservice>(new ClientCallBack(clientName), binding, endPoint); channel.Ping() When the endpoint doesn't exist it still waits 20seconds before throwing an EndpointNotFoundException. The weird thing is that when i changed the SendTimeout the exception message changed from The connection attempt lasted for a time span of 00:00:20 to ....01 but still took 20seconds to throw the exception! How can i change this timeout?

  • JPA getSingleResult() or null

    - by Eugene Ramirez
    Hi. I have an insertOrUpdate method which inserts an Entity when it doesn't exist or update it if it does. To enable this, I have to findByIdAndForeignKey, if it returned null insert if not then update. The problem is how do I check if it exists? So I tried getSingleResult. But it throws an exception if the public Profile findByUserNameAndPropertyName(String userName, String propertyName) { String namedQuery = Profile.class.getSimpleName() + ".findByUserNameAndPropertyName"; Query query = entityManager.createNamedQuery(namedQuery); query.setParameter("name", userName); query.setParameter("propName", propertyName); Object result = query.getSingleResult(); if(result==null)return null; return (Profile)result; } but "getSingleResult" throws an exception. Thanks

  • Use DLL and have it be as trusted as my own application is

    - by Binary255
    Hi, I am using a port of GNU GetOpts, to be specific I am using the one at: http://getopt.codeplex.com I have added the DLL as a reference. But when I run my application I receive an exception: System.IO.FileLoadException was unhandled Message="Could not load file or assembly 'Gnu.Getopt, Version=0.9.1.24287, Culture=neutral, PublicKeyToken=d014b4ccdc53511a' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418)" If it is possible I would like my application to say, "trust this DLL as much as you trust me". Is there a way to do that so I won't have to fiddle with security settings? And if there is not. What is the cleanest way to get the DLL working?

  • Unhandled exceptions in BackgroundWorker

    - by edg
    My WinForms app uses a number of BackgroundWorker objects to retrieve information from a database. I'm using BackgroundWorker because it allows the UI to remain unblocked during long-running database queries and it simplifies the threading model for me. I'm getting occasional DatabaseExceptions in some of these background threads, and I have witnessed at least one of these exceptions in a worker thread while debugging. I'm fairly confident these exceptions are timeouts which I suppose its reasonable to expect from time to time. My question is about what happens when an unhandled exception occurs in one of these background worker threads. I don't think I can catch an exception in another thread, but can I expect my WorkerCompleted method to be executed? Is there any property or method of the BackgroundWorker I can interrogate for exceptions?

  • Operation can only be performed on cells that belong to a DataGridView control

    - by The Demigeek
    The following code throws an InvalidOperationException with the above message and I don't understand why. My code calls the following method when the user may have made changes to the datagridview's underlying data source. The goal is to update the display with any changed data, and preserve the sort column and order. private void ReloadDataGridBindingListFromDatabase() { DataGridView dgv = myDataGridViewControl; DataGridViewColumn sortedColumn = dgv.SortedColumn; SortOrder sortOrder = dgv.SortOrder; //do stuff here to refresh dgv.DataSource if (sortedColumn != null) { //this line throws an exception sortedColumn.HeaderCell.SortGlyphDirection = sortOrder; } //etc. } Clearly, sortedColumn.HeaderCell is a cell that belongs to a DataGridView control. So why am I getting this exception? Many thanks for your input.

  • Fleunt NHibernate not working outside of nunit test fixtures

    - by thorkia
    Okay, here is my problem... I created a Data Layer using the RTM Fluent Nhibernate. My create session code looks like this: _session = Fluently.Configure(). Database(SQLiteConfiguration.Standard.UsingFile("Data.s3db")) .Mappings( m => { m.FluentMappings.AddFromAssemblyOf<ProductMap>(); m.FluentMappings.AddFromAssemblyOf<ProductLogMap>(); }) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); When I reference the module in a test project, then create a test fixture that looks something like this: [Test] public void CanAddProduct() { var product = new Product {Code = "9", Name = "Test 9"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); using (ISession session = OrmHelper.OpenSession()) { var fromDb = session.Get<Product>(product.Id); Assert.IsNotNull(fromDb); Assert.AreNotSame(fromDb, product); Assert.AreEqual(fromDb.Id, product.Id); } My tests pass. When I open up the created SQLite DB, the new Product with Code 9 is in it. the tables for Product and ProductLog are there. Now, when I create a new console application, and reference the same library, do something like this: Product product = new Product() {Code = "10", Name = "Hello"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); Console.WriteLine(product.Id); Console.ReadLine(); It doesn't work. I actually get pretty nasty exception chain. To save you lots of head aches, here is the summary: Top Level exception: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.\r\n\r\n The PotentialReasons collection is empty The Inner exception: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Both the unit test library and the console application reference the exact same version of System.Data.SQLite. Both projects have the exact same DLLs in the debug folder. I even tried copying SQLite DB the unit test library created into the debug directory of the console app, and removed the build schema lines and it still fails If anyone can help me figure out why this won't work outside of my unit tests it would be greatly appreciated. This crazy bug has me at a stand still.

  • How to display specific data from a file

    - by user1067332

  • C# Assembly Xna.Framework.dll does not load

    - by jbsnorro
    When trying to load Microsoft.Xna.Framework.dll from any project, it throws a FileNotFoundException. The specified module could not be found. (Exception from HRESULT: 0x8007007E), with no innerException. Even the simple code like the following throws that exception: static void Main(string[] args) { Assembly.LoadFile(@"C:\Microsoft.Xna.Framework.dll"); } I run XP x64, but I've set the platform in the configuration manager to x86, because I know it shouldn't(doesn't) work on x64 or Any CPU. I've manually added the dll file to GAC, but that didn't solve the problem. I have also tried the M$ Assembly Binding Log Viewer to see if those logs had any useful information, but they didn't. Everything, the loading etc, was a success according to them. Any suggestions? please?

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • Mysql: ROLLBACK for multiple queries

    - by Raj
    Hi I have more than three MySql queiries in a PHP script triggered by scheduled task. If a query catch an error, script throw an exception and rollback that Mysql query. It works fine. However if first query works fine, but not 2nd query, throw an exception, it rollback 2nd one but not 1st query. I am using begin_trans(), commit and rollback() for individual queries because Sometimes i need to rollback one query, sometimes all queries. Is there any way to rollback one query or all queries? Thanks in advance UPDATE: I got it working, there was no problem with in begin_trans(), commit and rollback(), the database connection config was different for one query from other queries, crazy code without any comments!!!

  • Constructor invocation returned null: what to do?

    - by strager
    I have code which looks like: private static DirectiveNode CreateInstance(Type nodeType, DirectiveInfo info) { var ctor = nodeType.GetConstructor(new[] { typeof(DirectiveInfo) }); if(ctor == null) { throw new MissingMethodException(nodeType.FullName, "ctor"); } var node = ctor.Invoke(new[] { info }) as DirectiveNode; if(node == null) { // ???; } return node; } I am looking for what to do (e.g. what type of exception to throw) when the Invoke method returns something which isn't a DirectiveNode or when it returns null (indicated by // ??? above). (By the method's contract, nodeType will always describe a subclass of DirectiveNode.) I am not sure when calling a constructor would return null, so I am not sure if I should handle anything at all, but I still want to be on the safe side and throw an exception if something goes wrong.

  • CouchDB Map/Reduce raises execption in reduce function?

    - by fuzzy lollipop
    my view generates keys in this format ["job_id:1234567890", 1271430291000] where the first key element is a unique key and the second is a timestamp in milliseconds. I run my view with this elapsed_time?startkey=["123"]&endkey=["123",{}]&group=true&group_level=1 and here is my reduce function, the intention is to reduce the output to get the earliest and latest timestamps and return the difference between them and now function(keys,values,rereduce) { var now = new Date().valueOf(); var first = Number.MIN_VALUE; var last = Number.MAX_VALUE; if (rereduce) { first = Math.max(first,values[0].first); last = Math.min(last,values[0].last); } else { first = keys[0][0][1]; last = keys[keys.length-1][0][1]; } return {first:now - first, last:now - last}; } and when processing a query it constantly raises the following execption: function raised exception (new TypeError("keys has no properties", "", 1)) I am making sure not to reference keys inside my rereduce block. Why does this function constantly raise this exception?

  • Issues with LINQ (to Entity) [adding records]

    - by Mario
    I am using LINQ to Entity in a project, where I pull a bunch of data (from the database) and organize it into a bunch of objects and save those to the database. I have not had problems writing to the db before using LINQ to Entity, but I have run into a snag with this particular one. Here's the error I get (this is the "InnerException", the exception itself is useless!): New transaction is not allowed because there are other threads running in the session. I have seen that before, when I was trying to save my changes inside a loop. In this case, the loop finishes, and it tries to make that call, only to give me the exception. Here's the current code: try { //finalResult is a list of the keys to match on for the records being pulled foreach (int i in finalResult) { var queryEff = (from eff in dbMRI.MemberEligibility where eff.Member_Key == i && eff.EffDate >= DateTime.Now select eff.EffDate).Min(); if (queryEff != null) { //Add a record to the Process table Process prRecord = new Process(); prRecord.GroupData = qa; prRecord.Member_Key = i; prRecord.ProcessDate = DateTime.Now; prRecord.RecordType = "F"; prRecord.UsernameMarkedBy = "Autocard"; prRecord.GroupsId = qa.GroupsID; prRecord.Quantity = 2; prRecord.EffectiveDate = queryEff; dbMRI.AddObject("Process", prRecord); } } dbMRI.SaveChanges(); //<-- Crashes here foreach (int i in finalResult) { var queryProc = from pro in dbMRI.Process where pro.Member_Key == i && pro.UsernameMarkedBy == "Autocard" select pro; foreach (var qp in queryProc) { Audit aud = new Audit(); aud.Member_Key = i; aud.ProcessId = qp.ProcessId; aud.MarkDate = DateTime.Now; aud.MarkedByUsername = "Autocard"; aud.GroupData = qa; dbMRI.AddObject("Audit", aud); } } dbMRI.SaveChanges(); //<-- AND here (if the first one is commented out) } catch (Exception e) { //Do Something here } Basically, I need it to insert a record, get the identity for that inserted record and insert a record into another table with the identity from the first record. Given some other constraints, it is not possible to create a FK relationship between the two (I've tried, but some other parts of the app won't allow it, AND my DBA team for whatever reason hates FK's, but that's for a different topic :)) Any ideas what might be causing this? Thank!

  • jQuery effect on iframe parent document

    Just wondering if anyone else has experienced this or knows why I am getting an error. I'm using javascript from within an iframe to call a parent dom element then use jQuery UI's effect core to shake it. Here is an example: $(document).ready(function(){ if ($("form").length>0) { $("form").submit(function(){ var oParentDoc = $(parent.document).find("div#element"); var action = $(this).attr("action"); var postdata = $(this).serialize(); $(oParentDoc).addClass("loading"); $.post(action,postdata,function(data){ $(oParentDoc).removeClass("loading").effect("shake",{"times":3,"distance":10},60); }); return false; }); } }); It works without the effect, but when I use an effect it gives me this error: uncaught exception: [Exception...

    So, if you try to do a nested class like this: //nestedtest.php class nestedTest{ function test(){ class E extends Exception{} throw new E; } } You will get an error Fatal error: Class declarations may not be nested in [...] but if you have a class in a separate file like so: //nestedtest2.php class nestedTest2{ function test(){ include('e.php'); throw new E; } } //e.php class E Extends Exception{} So, why does the second hacky way of doing it work, but the non-hacky way of doing it does not work?

  • Findbugs warning: Equals method should not assume anything about the type of its argument

    - by Uri
    When running FindBugs on my project, I got a few instances of the error described above. Namely, my overriding versions of equals cast the RHS object into the same type as the object in which the overriding version is defined. However, I'm not sure whether a better design is possible, since AFAIK Java does not allow variance in method parameters, so it is not possible to define any other type for the equals parameter. Am I doing something very wrong, or is FindBugs too eager? A different way to phrase this question is: what is the correct behavior if the object passed to equals is not the same type as an LHS: Is this a false, or should there be an exception? For example: public boolean equals(Object rhs) { MyType rhsMyType = (MyType)rhs; // Should throw exception if(this.field1().equals(rhsMyType.field1())... // Or whatever }
