  • How to run an exe which is added in the project

    - by Manish
    First of all I did gave a look at this one. But I didn't got the solution. The accepted anser says to use it like this: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "myExec.exe"; p.Start(); But this is not working for me. THe exception's message says "The system cannot find the specified file". Am I missing something? I added the exe directly to the project itself.

  • Prevent mapping all public members of a class in Fluent NHibernate

    - by alimbada
    I have a class generated from a WSDL that has a bunch of public properties and a public event. I'm extending this class with my own and adding some properties to it. All of my own properties are declared virtual, but the base class properties are not virtual. I'm using Fluent NHibernate's ClassMap to map only the properties from my extended class. How do I prevent (Fluent)NHibernate from trying to persist all the base class's public members? At the moment, I get the following exception when creating the ISessionFactory: NHibernate.InvalidProxyTypeException: The following types may not be used as proxies: Type: method get_<BaseClassProperty should be 'public/protected virtual' or 'protected internal virtual' Type: method set_<BaseClassProperty should be 'public/protected virtual' or 'protected internal virtual' ... Type: method add_<BaseClassEvent should be 'public/protected virtual' or 'protected internal virtual' Type: method remove_<BaseClassEvent should be 'public/protected virtual' or 'protected internal virtual'

  • Hibernate object equality checking

    - by Sujee
    As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.

  • Lambda expressions and nullable types

    - by Mathew
    I have two samples of code. One works and returns the correct result, one throws a null reference exception. What's the difference? I know there's some magic happening with capturing variables for the lambda expression but I don't understand what's going on behind the scenes here. int? x = null; bool isXNull = !x.HasValue; // this works var result = from p in data.Program where (isXNull) select p; return result.Tolist(); // this doesn't var result2 = from p in data.Program where (!x.HasValue) select p; return result2.ToList();

  • System.Linq.Dynamic and DateTime

    - by Matthew Hood
    I am using System.Linq.Dynamic to do custom where clauses from an ajax call in .Net MVC 1.0. It works fine for strings, int etc but not for DateTime, I get the exception cannot compare String to DateTime. The very simple test code is items = items.Where(string.Format(@" {0} {1}{2}{1} ", searchField, delimiter, searchString)); Where searchField will be for example start_date and the data type is DateTime, delimiter is " (tried with nothing as well) and searchString will be 01-Jan-2009 (tried with 01/01/2009 as well) and items is an IQueryable from LinqToSql. Is there a way of specifying the data type in a dynamic where, or is there a better approach. It is currently already using some reflection to work out what type of delimiter is required.

  • IL emit - operation could destabilize runtime when storing then loading

    - by Jakob Botsch Nielsen
    Hey, so I have the following IL: il.Emit(OpCodes.Ldarg_0); il.Emit(OpCodes.Ret); Which works fine. It basically returns the argument given. This, however: il.Emit(OpCodes.Ldarg_0); il.Emit(OpCodes.Stloc_0); il.Emit(OpCodes.Ldloc_0); il.Emit(OpCodes.Ret); Does not work. It crashes with the exception "Operation could destabilize the runtime.". Now, I know that the purpose of that is useless but I'm trying to reach my goal by small steps. Why does that not work?

  • How can I copy an XmlNode from one XmlDocument to another?

    - by Chris Wenham
    I'm building a tool that authors/edits XML files, and I want to be able to populate it with template fragments defined in another XML file. For example, the tool has an "Add FooBarBaz Element" button that adds a element to the new document being created, and I want to add FooBarBaz by copying it from a template. Or let's say this is my template file: <Templates> <FooBarBaz Attribute="Value"> <ChildElement/> </FooBarBaz> </Templates> I can then grab a template fragment with .GetElementsByTagName("FooBarBaz"), and I'd like to be able to inject it into the new document with something like .AppendChild(templateNode). But the problem is that an XmlNode cannot be copied from one XmlDocument to another, even if you use .Clone() or .CloneNode(), because AppendChild() throws an exception saying that the template element belongs to another context. Is there an easy way to copy a System.Xml.XmlNode between System.Xml.XmlDocuments?

  • How to do Linq aggregates when there might be an empty set?

    - by Shaul
    I have a Linq collection of Things, where Thing has an Amount (decimal) property. I'm trying to do an aggregate on this for a certain subset of Things: var total = myThings.Sum(t => t.Amount); and that works nicely. But then I added a condition that left me with no Things in the result: var total = myThings.Where(t => t.OtherProperty == 123).Sum(t => t.Amount); And instead of getting total = 0 or null, I get an error: System.InvalidOperationException: The null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type. That is really nasty, because I didn't expect that behavior. I would have expected total to be zero, maybe null - but certainly not to throw an exception! What am I doing wrong? What's the workaround/fix?

  • android: ListView.setAdapter() is causing IllegalStateException. Not sure how to fix it.

    - by Stev0
    I'm trying to populate a listview with the contents of various ListAdapters based upon the results of a switch statement nested in an OnItemClickListener. When clicking the item, the application was force closing, so I ran it through the dev tools and android debugger. Eclipse is showing me the in the main thread that the application has suspended due an IllegalStateException. I have a marginal understanding of what the particular exception indicates, but not sure how to fix it, or what in my code is causing it to be thrown. Code as follows: final ListView lv = (ListView) findViewById(R.id.main_list); final String[] autos = getResources().getStringArray(R.array.auto_array); final ListAdapter la_auto = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_2, autos); And then further down in the portion dealing with the onclicklistener gallery.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { switch(gallery.getSelectedItemPosition()) { case 0: lv.setAdapter(la_auto); break;

  • No-overflow cast on x64

    - by Cheeso
    I have an existing C codebase that works on x86. I'm now compiling it for x64. What I'd like to do is cast a size_t to a DWORD, and throw an exception if there's a loss of data. Q: Is there an idiom for this? Here's why I'm doing this: A bunch of Windows APIs accept DWORDs as arguments, and the code currently assumes sizeof(DWORD)==sizeof(size_t). That assumption holds for x86, but not for x64. So when compiling for x64, passing size_t in place of a DWORD argument, generates a compile-time warning. In virtually all of these cases the actual size is not going to exceed 2^32. But I want to code it defensively and explicitly. This is my first x64 project, so... be gentle.

  • Azure Blobs - ArgumentNullException when calling UploadFile()

    - by Ariel
    I’m getting the following exception when trying to upload a file with the following code: string encodedUrl = "videos/Sample.mp4" CloudBlockBlob encodedVideoBlob = blobClient.GetBlockBlobReference(encodedUrl); Log(string.Format("Got blob reference for {0}", encodedUrl), EventLogEntryType.Information); encodedVideoBlob.Properties.ContentType = contentType; encodedVideoBlob.Metadata[BlobProperty.Description] = description; encodedVideoBlob.UploadFile(localEncodedBlobPath); I see the "Got blob reference" message, so I assume the reference resolves correctly. Void Run() C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs (40) System.ArgumentNullException: Value cannot be null. Parameter name: value at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.get_Result() at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.ExecuteAndWait() at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFromStream(Stream source, BlobRequestOptions options) at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFile(String fileName, BlobRequestOptions options) at EncoderWorkerRole.WorkerRole.ProcessJobOutput(IJob job, String videoBlobToEncodeUrl) in C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs:line 144 at EncoderWorkerRole.WorkerRole.Run() in C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs:line 40 Interestingly, I'm running that same snippet from an on-premises server i.e., outside of Azure and it works correctly. Ideas welcome, thanks!

  • Why would MessageBox fail silently?

    - by Tim Gradwell
    Does anyone know how MessageBox(...) could fail silently? MessageBox(g_hMainhWnd, buffer, "Oops!", MB_OK | MB_ICONERROR); ShellExecute(0, "open", "http://intranet/crash_handler.php", NULL, "", SW_SHOWNORMAL); For a little context, this code is called inside our own exception handler, which was registered with SetUnhandledExceptionFilter() Most of the time, I see the message box, and then it launches a web browser. However, I have an exe, which as far as I'm aware uses this exact code, and it successfully launches the web browser, but I do not see the message box first. Thanks Tim

  • last_login_at not working (null) w/ Authlogic Magic Columns...

    - by bgadoci
    I am using the Authlogicgem for authentication and most of it seems to be working great. Authlogic provides several columns that you can add to your Users table (for example) that it knows to fill in if they are present. i.e. login_count, current_login_ip, last_request_at and last_login_at. All seem to be working fine with the exception of the last_login_at field which is null for each user. Is there anything specific that could be causing this perhaps having to do with the user sessions, etc? I can post code if needed but wasn't sure what would relate to this.

  • Error handling and polymorphism

    - by Neeraj
    I have an application with some bunch of code like this: errCode = callMainSystem(); switch (errCode){ case FailErr: error("Err corresponding to val1\n"); case IgnoreErr: error("Err corresponding to val2\n"); ... ... default: error("Unknown error\n"); } The values are enum constants. Will it make some sense to have something like: // Error* callMainSystem() ... Some code return FaileErr(); // or some other error // handling code Error* err = callMainSystem(); err->toString(); The Error class may be made singleton as it only has to print error messages. What are the pros and cons of above methods,size is an important criteria as the application needs to be supported on embedded devices as well. P.S: I don't want to use exception handling because of portability issues and associated overheads.

  • FluentNHibernate: returning an enum from a derived property

    - by Zen-C
    I'm using the automapping feature of FluentNHibernate and need a property that derives its return value. This property must return an Enum value, e.g. public virtual MyEnum MyDerivedProperty { get { MyEnum retval; // do some calculations return retval; } } Currently I get the following exception: NHibernate.PropertyNotFoundException: Could not find a setter for property 'MyDerivedProperty' ... If I add a setter then the database table involved requires the column to exist, even if that setter does nothing. It works fine when the return type is an int. Any ideas how I achieve this?

  • Dynamically create PHPUnit tests from data-file

    - by DeletedAccount
    I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

  • how to handle exceptions/errors in php?

    - by fayer
    when using 3rd part libraries they tend to throw exceptions to the browser and hence kill the script. eg. if im using doctrine and insert a duplicate record to the database it will throw an exception. i wonder, what is best practice for handling these exceptions. should i always do a try...catch? but doesn't that mean that i will have try...catch all over the script and for every single function/class i use? Or is it just for debugging? i don't quite get the picture. Cause if a record already exists in a database, i want to tell the user "Record already exists". And if i code a library or a function, should i always use "throw new Expcetion($message, $code)" when i want to create an error? Please shed a light on how one should create/handle exceptions/errors. Thanks

  • How do I programmatically add an Android Gestures view to a custom view?

    - by user351201
    I have a custom view that works fine and I'm trying to get gestures into it. The most common technique I see is to add XML, such as this (from Android docs: My view is within a RelativeView and when I attempt to reference this GetureOverlayView, I get an exception. I've also tried to connect within my existing custom view class, like this: mGestures = new GestureOverlayView(context, attrs); mGestures.addOnGesturePerformedListener(this); But the callback is never invoked. Can someone see my errors or suggest a better way that will allow me to get gesture callbacks?
