  • The best way to package iPhone/iPad static libraries?

    - by Derek Clarkson
    Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

  • Could not load type in Custom Profile provider

    - by Cragly
    I am writing a small console application in C# that references a custom assembly that implements custom .net Profile provider. I have added the following sections to my app.config file which references the custom class and assembly. <system.web> <profile defaultProvider="MyCompanyProfileProvider" inherits="MyCompany.Web.User.GenericProfile" automaticSaveEnabled="false"> <providers> <clear/> <add name="MyCompanyProfileProvider" connectionStringName="defaultDatabase" applicationName="/myApplication" type="MyCompany.Web.ProfileProvider, MyCompany.Web"/> </providers> <properties> <add name="JobRoleId" type="System.Int32"/> <add name="LastCompetencyId" type="System.Int32" defaultValue="0"/> <add name="MixSettings" type="System.Xml.XmlDocument"/> </properties> </profile></system.web> However when I run the app in debug mode I get the following error as if it is looking in the System.Web assembly rather than one specified in the app.config file. Could not load type 'MyCompany.Web.User.GenericProfile' from assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. I have a local web app that also uses the assembly and custom Profile provider and that work without any problems. I have checked the referenced assembly is being copied to the output directory. Any ideas??

  • ODBC: Mapping of literal type names in create table statements

    - by matthias-meyer
    I was wondering if data types in a a literal "create table" statement, executed over ODBC, are replaced with their database specific counterparts (platform is Windows/.Net/C#). I cannot find this feature in the ODBC docs, and there seems to be no list of literal "ODBC data types". However, I know that this works for Oracle, SQL Server and Access; the following statement is executed correctly, although the type LONGVARBINARY is no native type in all of these systems: CREATE TABLE (MYCOLUMN LONGVARBINARY) However, e.g. for Oracle the mapped native type depends on the used ODBC driver. Is this an undocumented feature? Is there a list of supported type names anywhere? Thanks!

  • DomainContext class is not created in a RIA services class library solution

    - by Konamiman
    I have created a RIA services class library project and things are not going as I expected. The problem is that when I add domain service classes to the server project, the corresponding domain context classes are not generated on the client project. I start by creating a new project of type WCF RIA services class library. The generated solution has two projects: RIAServicesLibrary1 (the Silverlight class library project) and RIAServicesLibrary1.Web (the class library that will hold the services). Then I add a new project item to RIAServicesLibrary1.Web of type DomainServiceClass. I add a sample method so that the resulting class code is: namespace RIAServicesLibrary1.Web { using System; using System.Collections.Generic; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Linq; using System.ServiceModel.DomainServices.Hosting; using System.ServiceModel.DomainServices.Server; // TODO: Create methods containing your application logic. [EnableClientAccess()] public class DomainService1 : DomainService { [Invoke] void DoSomething() { } } } Then I generate the whole solution and... nothing happens on the client project. The Generated_Code folder is empty, and the domain context object for the service is not here. Funny enough, if I add a new item of type Authentication domain service, it works as expected: the file RIAServicesLibrary1.Web.g.cs is created on the client project, containing the AuthenticationDomainService1 class as expected. So what's happening here? Am I doing something wrong? Note: I am using Visual Studio 2010 Ultimate RTM and WCF RIA services 1.0.

    How can I specify the content type of an attachment when sending emails using sp_send_dbmail? The content type is specified as application/octet-stream for Zip, PDF files. But I need to change it to application/zip, application/pdf. The "file_attachments" parameter takes absolute paths of the attachments. Can not find a place to specify content type. I am using SQL Server 2005/2008 Please help. Thanks

  • Java Generics: Dealing with an intermediate unknown type

    - by Matt
    I am trying to figure out a way to deal with a particular problem in a type safe manner, or to put it more specifically without any explicit casts. I have a class that takes in a generic request and returns a generic response like such: public class RetrievalProcessor<Req extends Request, Resp> implements RequestProcessor<Req, Resp>{ private Dao<Req> dao; private RawResponseTransformer<Resp> transformer; @Override public Resp process(Req request) { return transformer.transformResponse(dao.retrieveRawResponse(request)); } } My problem is the following. My Dao object can be many different things REST, JDBC, some other proprietary object. I can't be certain of the type of object that the Dao will return. I do know the type of object my caller would like and that is the Resp type on the generic, and the job of the RawResponseTransformer is to transform that Dao response into something that the caller can consume. The problem I have is I can't figure out a way that feels clean to do that. I have considered putting the intermediate type as part of the definition of the class, but it doesn't seem like the caller should know, or really care, what the intermediate form is. Hoping someone might have a good clean idea for handling this.

  • "type not defined" exception with WF4 RC

    - by avi1234
    Hi, I`m gettin the following exception while invoking my workflow (dynamically): The following errors were encountered while processing the workflow tree: 'DynamicActivity': The private implementation of activity '1: DynamicActivity' has the following validation error: Compiler error(s) encountered processing expression "TryCast(simplerule_out,OutputBase2)". Type 'OutputBase2' is not defined. 'DynamicActivity': The private implementation of activity '1: DynamicActivity' has the following validation error: Compiler error(s) encountered processing expression "Res".

  • C# - Cast object to IList<T> based on Type

    - by blu
    I am trying out a little reflection and have a question on how the cast the result object to an IList. Here is the reflection: private void LoadBars(Type barType) { // foo has a method that returns bars Type foo = typeof(Foo); MethodInfo method = foo.GetMethod("GetBars") .MakeGenericMethod(bar); object obj = method.Invoke(foo, new object[] { /* arguments here */ }); // how can we cast obj to an IList<Type> - barType } How can we cast the result of method.Invoke to an IList of Type from the barType argument?

  • Get CLSID by PIA interface Type

    - by Charles
    How can I get the CLSID for a given interface within a Primary Interop Assembly? Here's what I'm talking about: // The c# compiler does some interesting magic. // The following code ... var app = new Microsoft.Office.Interop.Outlook.Application(); // ... is compiled like so (disassembled with Reflector): var app =((Microsoft.Office.Interop.Outlook.Application) Activator.CreateInstance(Type.GetTypeFromCLSID(new Guid("0006F03A-0000-0000-C000-000000000046")))); Microsoft.Office.Interop.Outlook.Application is an interface, and therefore it cannot be instantiated directly. What's interesting here is that c# lets you treat these COM interfaces as if there where classes that you can instantiate with the new keyword. What I want to know is, given the System.Type for a given interface, how can I get the CLSID? Note: I ultimately want to be able to create an instance given the interface's System.Type - I don't really care how. I'm assuming here that the easiest way to do this would be to get CLSID given the Type, just as the c# compiler does.

  • healthy DLL reference broken after compile multi-project solution

    - by Code Sherpa
    Hi. I have a solution with multiple class libraries. When I compile each individual library (and the web site by itself) compilation always succeeds. But, when I compile the solution as a whole, one of the library references fails with a little yellow exclamation mark next to the failed library. I am guessing this has to do with the build order? Can somebody suggest what i have to do to resolve this? Thanks in advance.

  • Java Generics Type Safety warning with recursive Hashmap

    - by GC
    Hi, I'm using a recursive tree of hashmaps, specifically Hashmap map where Object is a reference to another Hashmap and so on. This will be passed around a recursive algorithm: foo(String filename, Hashmap<String, Object> map) { //some stuff here for (Entry<String, Object> entry : map.entrySet()) { //type warning that must be suppressed foo(entry.getKey(), (HashMap<String, Object>)entry.getValue()); } } I know for sure Object is of type Hashmap<String, Object> but am irritated that I have to suppress the warning using @SuppressWarnings("unchecked"). I'll be satisfied with a solution that does either a assert(/*entry.getValue() is of type HashMap<String, Object>*/) or throws an exception when it isn't. I went down the Generics route for compile type safety and if I suppress the warning then it defeats the purpose. Thank you for your comments, ksb

  • Primitive type 'short' - casting in Java

    - by gemm
    Hello, I have a question about the primitive type 'short' in Java. I am using JDK 1.6. If I have the following: short a = 2; short b = 3; short c = a + b; the compiler does not want to compile - it says that it "cannot convert from int to short" and suggests that I make a cast to short, so this: short c = (short) (a + b); really works. But my question is why do I need to cast? The values of a and b are in the range of short - the range of short values is {-32,768, 32767}. I also need to cast when I want to perform the operations -, *, / (I haven't checked for others). If I do the same for primitive type int, I do not need to cast aa+bb to int. The following works fine: int aa = 2; int bb = 3; int cc = aa +bb; I discovered this while designing a class where I needed to add two variables of type short, and the compiler wanted me to make a cast. If I do this with two variables of type int, I don't need to cast. Thank you very much in advance. A small remark: the same thing also happens with the primitive type byte. So, this workes: byte a = 2; byte b = 3; byte c = (byte) (a + b); but this not: byte a = 2; byte b = 3; byte c = a + b; For long, float, double, and int, there is no need to cast. Only for short and byte values.

  • Can't change data type on MS Access 2007

    - by khalidfazeli
    Hi All, I have a huge database (800MB) which consists of a field called 'Date Last Modified' at the moment this field is entered as a text data type but need to change it to a Date/Time field to carry out some queries. I have another exact same database but with only 35MB of data inside it and when I change the data type it works fine, but when I try to change data type on big database it gives me an error: Micorosoft Office Access can't change the data type. There isn't enough disk space or memory After doing some research some sites mentioned of changing the registry file (MaxLocksPerFile) tried that as well, but no luck :-( Can anyone help please?

  • Cast to generic type in C#

    - by Andrej
    I have a Dictionary to map a certain type to a certain generic object for that type. For example: typeof(LoginMessage) maps to MessageProcessor<LoginMessage> Now the problem is to retrieve this generic object at runtime from the Dictionary. Or to be more specific: To cast the retrieved object to the specific generic type. I need it to work something like this: Type key = message.GetType(); MessageProcessor<key> processor = messageProcessors[key] as MessageProcessor<key>; Hope there is a easy solution to this. Edit: I do not want to use Ifs and switches. Due to performance issues I cannot use reflection of some sort either.

  • gettype and unknown type in php

    - by justjoe
    i just start to practice with php built-in, gettype() and its return value. This function is capable to return testing result such as boolean, integer, unknown type, etc. But among those testing result, there's one caught my eyes : unknown type. After reading gettype, and try to find some reference here, i can not get any. So, the question is what kind of type can be categorized as "unknown type" ? is it possible ? or am i just missing reading something ?

  • Delphi Unicode String Type Stored Directly at its Address

    - by Andreas Rejbrand
    I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right?

  • Does C# have an equivalent to Scala's structural typing?

    - by Tom Morris
    In Scala, I can define structural types as follows: type Pressable { def press(): Unit } This means that I can define a function or method which takes as an argument something that is Pressable, like this: def foo(i: Pressable) { // etc. The object which I pass to this function must have defined for it a method called press() that matches the type signature defined in the type - takes no arguments, returns Unit (Scala's version of void). I can even use the structural type inline: def foo(i: { def press(): Unit }) { // etc. It basically allows the programmer to have all the benefits of duck typing while still having the benefit of compile-time type checking. Does C# have something similar? I've Googled but can't find anything, but I'm not familiar with C# in any depth. If there aren't, are there any plans to add this?

  • MIDP 2.0 version issues: $method is undefined for $type

    - by Kilnr
    Hi, I've written a MIDlet that does several "advanced" things: fetching images from the web, resizing them, saving them on the phone, displaying them. This all works perfectly in the Nokia S60 3rd Edition FP1 emulator. This device has MIDP 2.0 and CLDC 1.1 support (also JSR75, which I need in order to save files). It also works as it should on the Nokia E71 (physical device). I then tried to run the MIDlet on several other emulators. One of them, the DefaultCldcJtwiPhone2 from the Java ME SDK 3.0, also claims MIDP 2.0 and CLDC 1.1 support. It doesn't have JSR75, which explains why "FileConnection can not be resolved to a type". This does not, however, explain why List.deleteAll(), String.equalsIgnoreCase(String) and a few others are undefined. The actual errors that I get: The method ceil(double) is undefined for the type Math The method deleteAll() is undefined for the type List The method equalsIgnoreCase(String) is undefined for the type String The method getWidth() is undefined for the type Displayable When I look at the MIDP 2.0 (i.e. JSR118) API (http://java.sun.com/javame/reference/apis/jsr118/), I can clearly see all of these methods being present, with the "since" tag being either MIDP 2.0 or CLDC 1.1. My question: why doesn't an emulator with MIDP 2.0 support have access to all MIDP 2.0 methods? Or alternatively, what am I doing wrong?

  • XmlSerializer throws exception when serializing dynamically loaded type

    - by Dr. Sbaitso
    Hi I'm trying to use the System.Xml.Serialization.XmlSerializer to serialize a dynamically loaded (and compiled class). If I build the class in question into the main assembly, everything works as expected. But if I compile and load the class from an dynamically loaded assembly, the XmlSerializer throws an exception. What am I doing wrong? I've created the following .NET 3.5 C# application to reproduce the issue: using System; using System.Collections.Generic; using System.Xml.Serialization; using System.Text; using System.Reflection; using System.CodeDom.Compiler; using Microsoft.CSharp; public class StaticallyBuiltClass { public class Item { public string Name { get; set; } public int Value { get; set; } } private List<Item> values = new List<Item>(); public List<Item> Values { get { return values; } set { values = value; } } } static class Program { static void Main() { RunStaticTest(); RunDynamicTest(); } static void RunStaticTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing StaticallyBuiltClass..."); Console.WriteLine("-------------------------------------"); var stat = new StaticallyBuiltClass(); Serialize(stat.GetType(), stat); Console.WriteLine(); } static void RunDynamicTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing DynamicallyBuiltClass..."); Console.WriteLine("-------------------------------------"); CSharpCodeProvider csProvider = new CSharpCodeProvider(new Dictionary<string, string> { { "CompilerVersion", "v3.5" } }); CompilerParameters csParams = new System.CodeDom.Compiler.CompilerParameters(); csParams.GenerateInMemory = true; csParams.GenerateExecutable = false; csParams.ReferencedAssemblies.Add("System.dll"); csParams.CompilerOptions = "/target:library"; StringBuilder classDef = new StringBuilder(); classDef.AppendLine("using System;"); classDef.AppendLine("using System.Collections.Generic;"); classDef.AppendLine(""); classDef.AppendLine("public class DynamicallyBuiltClass"); classDef.AppendLine("{"); classDef.AppendLine(" public class Item"); classDef.AppendLine(" {"); classDef.AppendLine(" public string Name { get; set; }"); classDef.AppendLine(" public int Value { get; set; }"); classDef.AppendLine(" }"); classDef.AppendLine(" private List<Item> values = new List<Item>();"); classDef.AppendLine(" public List<Item> Values { get { return values; } set { values = value; } }"); classDef.AppendLine("}"); CompilerResults res = csProvider.CompileAssemblyFromSource(csParams, new string[] { classDef.ToString() }); foreach (var line in res.Output) { Console.WriteLine(line); } Assembly asm = res.CompiledAssembly; if (asm != null) { Type t = asm.GetType("DynamicallyBuiltClass"); object o = t.InvokeMember("", BindingFlags.CreateInstance, null, null, null); Serialize(t, o); } Console.WriteLine(); } static void Serialize(Type type, object o) { var serializer = new XmlSerializer(type); try { serializer.Serialize(Console.Out, o); } catch(Exception ex) { Console.WriteLine("Exception caught while serializing " + type.ToString()); Exception e = ex; while (e != null) { Console.WriteLine(e.Message); e = e.InnerException; Console.Write("Inner: "); } Console.WriteLine("null"); Console.WriteLine(); Console.WriteLine("Stack trace:"); Console.WriteLine(ex.StackTrace); } } } which generates the following output: ------------------------------------- Serializing StaticallyBuiltClass... ------------------------------------- <?xml version="1.0" encoding="IBM437"?> <StaticallyBuiltClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Values /> </StaticallyBuiltClass> ------------------------------------- Serializing DynamicallyBuiltClass... ------------------------------------- Exception caught while serializing DynamicallyBuiltClass There was an error generating the XML document.
