  • assignment not working in a dll exported C++ class

    - by Jim Jones
    Using VS 2008 Have a C++ class in which I'm calling functions from a 3rd party dll. The definition in the header file is as follows: namespace OITImageExport { class ImageExport { private: SCCERR seResult; /* Error code returned. */ VTHDOC hDoc; /* Input doc handle returned by DAOpenDocument(). */ VTHEXPORT hExport; /* Handle to the export returned by EXOpenExport(). */ VTDWORD dwFIFlags; /* Used in setting the SCCOPT_FIFLAGS option. */ VTCHAR szError[256]; /* Error string buffer. */ VTDWORD dwOutputId; /* Output Format. */ VTDWORD dwSpecType; public: ImageExport(const char* outputId, const char* specType); void ProcessDocument(const char* inputPath, const char* outputPath); ~ImageExport(); }; } In the constructor I initialize two of the class fields having values which come from enumerations in the 3rd party dll: ImageExport::ImageExport(const char* outputId, const char* specType) { if(outputId == "jpeg") { dwOutputId = FI_JPEGFIF; } if(specType == "ansi") { dwSpecType = IOTYPE_ANSIPATH; } seResult = DAInit(); if (seResult != SCCERR_OK) { DAGetErrorString(seResult, szError, sizeof(szError)); fprintf(stderr, "DAInit() failed: %s (0x%04X)\n", szError, seResult); exit(seResult); } } When I use this class inside of a console app, with a main method in another file (all in the same namespace), instantiating the class object and calling the methods, it works like a champ. So, now that I know the basic code works, I open a dll project using the class header and code file. Course I have to add the dll macro, namely: #ifdef IMAGEDLL_EXPORTS #define DLL __declspec(dllexport) #else #define DLL __declspec(dllimport) #endif and changed the class definition to "class DLL ImageExport". Compiled nicely to a dll and .lib file (No errors, No warnings). Now to test this dll I open another console project using the same main method as before and linking to the (dll) lib file. Had problems, which when tracked down were the result of the two fields not being set; both had values of 0. Went back to the first console app and printed out the values: dwOutputId was 1535 (#define FI_JPEGFIF 1535) and dwSpecType was 2 (#define IOTYPE_ANSIPATH 2). Now if I was assigning these values outside of the class, I can see how the visibility could be different, but why is the assignment in the dll not working? Is it something about having a class in the dll?

  • Focus next textview automatically

    - by Naseer
    I have a TextView with android:maxLength set to 3 and another with android:maxLength set to 7. I want focus to automatically move to the second TextView once the 3 chars of the first TextView are filled up. Is this possible without inheriting TextView and writing a custom implementation ?

  • C# Type Casting at Runtimefor Array.SetValue

    - by sprocketonline
    I'm trying to create an array using reflection, and insert values into it. I'm trying to do this for many different types so would like a createAndFillArray function capable of this : Type t1 = typeof(A); Type t2 = typeof(B); double exampleA = 22.5; int exampleB = 43; Array arrA = createAndFillArray(t1, exampleA); Array arrB = createAndFillArray(t2, exampleB); private Array createAndFillArray(Type t, object val){ Array arr = Array.CreateInstance( t, 1); //length 1 in this example only, real-world is of variable length. arr.SetValue( val, 0 ); //this causes the following error: "System.InvalidCastException : Object cannot be stored in an array of this type." return arr; } with the class A being as follows: public class A{ public A(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator A(double d){ A a = new A(); a.Value = d; return a; } } and class B being very similar, but with int: public class B{ public B(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator B(double d){ B b = new B(); b.Value = d; return b; } } I hoped that the implicit operator would have ensured that the double be converted to class A, or the int to class B, and the error avoided; but this is obviously not so. The above is used in a custom deserialization class, which takes data from a custom data format and fills in the corresponding .Net object properties. I'm doing this via reflection and at runtime, so I think both are unavoidable. I'm targeting the C# 2.0 framework. I've dozens, if not hundreds, of classes similar to A and B, so would prefer to find a solution which improved on the createAndFillArray method rather than a solution which altered these classes.

  • Batch adding attribute to attribute sets

    - by JonB
    I have a Magento installation with around 60 attribute sets. I need to add a new attribute to each of the attribute sets. There doesn't seem to anyway of doing this in the admin control panel. I am sure I can work it out by manually entering the correct fields into the database, but is there a way of doing this through the API or through the Import / Export profiles? Any suggestions would be gladly received.

  • How to seperate the model from the view?

    - by geejay
    I have a bunch of model objects. These objects end up being rendered as views (say forms) in a rich client app. I started to annotate the fields in the model objects (Java annotations) with things that let me render them as forms on the fly (e.g displayname, group, page, validvalues). I now realise that the view has crept into the model. How should I seperate the view logic out of the model objects? TECH: Java, Java Annotations, Eclipse RCP

  • Default App Icon not appearing in iOS Simulator

    - by user577466
    I have searched quite a lot for an answer to this problem. If I have a general application, HelloWorld, and create an interface and then go to test it, then click on the Home button, not even the default grey/white icon is there like it's supposed to be. Anyone have any ideas why? I've even tried specifying a custom icon in the Info.plist file, but still nothing... I've got the latest version of Xcode and the SDK as well. (3.25 - 4.2)

  • How is the default constructor of System.Drawing.Graphics removed?

    - by Albert Iordache
    When I try to create an object of Graphics, why doesn't the following work? System.Drawing.Graphics graphicsObj = new System.Drawing.Graphics(); (I am aware that I could create a private System.Windows.Forms.Panel Obj; and then do CreateGraphics() if I wanted it to work) I tried to find a custom constructor for Graphics, but I couldn't find one. Where did Microsoft define it, or how did it block it?

  • jquery event listening, non-standard events

    - by Stacey
    I'm attempting to build a way for my selectors to 'listen' to 'global' events that are beyond the typical 'click' 'change' 'submit' etc. I've explored the various 'eventmanagers' that I could find, and they're all still designed for forms. Is there any way to do something like this for non-standard (i.e. custom) events? The goal is to have selectors subscribe to an event, and then be able to trigger it in one place and it will raise it for everything subscribed to it.

  • How to show own view in Spinner Widget instead of Text View?

    - by Janusz
    I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item. It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row. I simply want to show an individual icon left from the spinner text for each item in the list.

    To use methods of a class I need to instantiate a class. At the moment the class has not constructor (so I want to write it). But than I have realized that the constructor should do nothing (I do need to specify values of fields). In this context I have a question if it is OK to write constructor which does nothing. For example: public Point() { }
