  • Create empty C# event handlers automatically

    - by TomA
    It is not possible to fire an event in C# that has no handlers attached to it. So before each call it is necessary to check if the event is null. if ( MyEvent != null ) { MyEvent( param1, param2 ); } I would like to keep my code as clean as possible and get rid of those null checks. I don't think it will affect performance very much, at least not in my case. MyEvent( param1, param2 ); Right now I solve this by adding an empty inline handler to each event manually. This is error prone, since I need to remember to do that etc. void Initialize() { MyEvent += new MyEvent( (p1,p2) => { } ); } Is there a way to generate empty handlers for all events of a given class automatically using reflection and some CLR magic?

  • GDI+ DrawImage function

    - by ET
    There is something I am missing. Say I have the following code: private Bitmap source = new Bitmap (some_stream); Bitmap bmp = new Bitmap(100,100); Rectangle newRect = new Rectangle(0, 0, bmp.Width, bmp.Height); Rectangle toZoom= new Rectangle(0, 0, 10, 10); Graphics g = Graphics.FromImage(bmp); g.DrawImage(source, newRect, toZoom, GraphicsUnit.Pixel); My goal is to zoom-in the 10x10 pixels on the top left corner of the source picture. After I created the graphics object g and called DrawImage: the requested rectangle (toZoom) will be copied to bmp, or will it be displayed on the screen? I am a bit confused, can somebody please clarify?

  • Wicket @SpringBean doesn't create serializable proxy

    - by vinga
    @SpringBean PDLocalizerLogic loc; When using above I receive java.io.NotSerializableException. This is because loc is not serializable, but this shouldn't be problem because spring beans are a serializable proxies. On the page https://cwiki.apache.org/WICKET/spring.html#Spring-AnnotationbasedApproach is written: Using annotation-based approach, you should not worry about serialization/deserialization of the injected dependencies as this is handled automatically, the dependencies are represented by serializable proxies What am I doing wrong?

  • Application.Current changes when using reflection to create an instance of another Application class

    - by markti
    Let's say I have the following Silverlight Applications: App1.xap App2.xap App3.xap Let's say that I start App1.xap as the default xap file. If I load App2.xap and App3.xap and instantiate an Application class within one of the other two XAPs. The Application.Current changes to be that new instance. System.Windows.Application obj = Activator.CreateInstance(type) as System.Windows.Application; I don't want the current application to change. I just want to get the merged Resource Dictionaries off the Application class.

  • Codeigniter: user defined helper function does not load.

    - by cbrandolino
    Hi everybody. I made a custom helper extending the system string_helper.php. I placed it in my /application/helpers folder, called MY_string_helper.php as required, unit-tested its functions. Now, when I try to call one of its functions from a model, it does not work. The functions in the default string helper work, instead. It looks like my extension is not loaded for some reasons. Thanks a lot, and happy holidays.

  • Taking 2 attributes from XElement to create a dictionary LINQ

    - by AndyC
    I'm trying to take one attribute to use as the key, and another to use as the value. If I use (xDoc is an XDocument object in the example): Dictionary<string, XElement> test = xDoc.Descendants() .Where<XElement>(t => t.Name == "someelement") .ToDictionary<XElement, string>(t => t.Attribute("myattr").Value.ToString()); I get a dictionary with the myattr value as key (which is what I want) but the entire XElement object as the value. What I want to do, is to select a second attribute to set as the value property on each dictionary item, but can't seem to figure that out. Is it possible to do all of this in 1 Linq statement? Curiousity has caught me! Cheers!

  • Create unique file name and fetching it to commandline argument

    - by user343934
    Hi everyone, I am working on python right now and i am little bit stuck in performing some tricks. I have web form with two options- File upload and textarea, i can easily pass file name with file upload options but have problem when it's textarea. Because when i use textarea then first i have to save values passed from textarea to some files and save it on the working directory. After that i can execute commandline argument and pass same saved filename name. For this problem i have to generate unique file first and save the values passed from textarea in it. Can anybody give me some tips to solve my problem. Any algorithms, suggestions and lines of code are appreciated. Thanks for your concern

  • How to create unique user key

    - by Grayson Mitchell
    Scenario: I have a fairly generic table (Data), that has an identity column. The data in this table is grouped (lets say by city). The users need an identifier in order for printing on paper forms, etc. The users can only access their cites data, so if they use the identity column for this purpose they will see odd numbers (e.g. a 'New York' user might see 1,37,2028... as the listed keys. Idealy they would see 1,2,3... (or something similar) The problem of course is concurrency, this being a web application you can't just have something like: UserId = Select Count(*)+1 from Data Where City='New York' Has anyone come up with any cunning ways around this problem?

  • Trying to create C++/CLI assembly for use in .NET

    - by Bad Man
    I'm trying to bring a C++ library into C#, so naturally I am trying to make a C++/CLI project. In visual studio I created a new project (Visual C++ project, class library). I then tried to make a test class out of the pre-generated "Class1" namespace Test { public ref class TestIt { public: void DoWork() { System::Console::WriteLine("sup"); } // TODO: Add your methods for this class here. }; } So I compile in and go to the build folder.... hrmm no .dll wetf?? There's a .dll.intermediate.manifest file, but no .dll. So wut I did wrong?

  • How to create GUI as inner class with WindowBuilder

    - by Tim Kemp
    I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

  • Deeper function profiling/emulation

    - by Syntax_Error
    Hello everyone Merry Christmas I need an advice I have the following code: int main() { int k=5000000; int p; int sum=0; for (p=0;p<k;p++) { sum+=p; } return 0; } When I assemble it I get main: pushl %ebp movl %esp, %ebp subl $16, %esp movl $5000000, -4(%ebp) movl $0, -12(%ebp) movl $0, -8(%ebp) jmp .L2 .L3: movl -8(%ebp), %eax addl %eax, -12(%ebp) addl $1, -8(%ebp) .L2: movl -8(%ebp), %eax cmpl -4(%ebp), %eax jl .L3 movl $0, %eax leave ret If I run it through gprof I get that main executed the most, which is quite obvious! Yet I want to go a step further and be able to know if L2, or L3 executed the most. here it is obvious that L3 executed the most. yet is there some kind of profiler, emulator that can give me that data for an entire code?

    Please see pic, this is what I want to do. I am really struggling to bloody do it lol. The master div, is 600px wide ( blue bg ) and need splitting into two areas, left for the image and right for the text etc. Ignore the vertical divider line The left hand div, is approx 200px wide, and need to specify a min-height of 100px, as the placeholder image which is centered to that div 50% 50% will change size, as I will be adding another div like this with larger image placeholder. The right part contains the header tag, description, button and second description. I have already constructed this and works fine in chrome and ff, but not in ie. So could you guys have a think, and give me some code that complies in all browsers. It is officially doing my head in now. Screenpic of it working in ff and chrome below:

  • Function returning pointer to struct

    - by GammaGuy
    I am having some issues with code that is returning a pointer to a struct declared inside a class. Here is my code so far: SortedList.h #ifndef SORTEDLIST_H #define SORTEDLIST_H class SortedList{ public: SortedList(); ... private: struct Listnode { Student *student; Listnode *next; }; static Listnode *copyList (Listnode *L); }; #endif SortedList.cpp #include "SortedList.h" ... // Here is where the problem lies Listnode SortedList::*copyList(Listnode *L) { return 0; // for NULL } Apparently, the copy list method wont compile. I am using Microsoft Visual Studio and the compiler tells me that "Listnode" is unidentified. When I try to compile, here is whhat I get: 1>------ Build started: Project: Program3, Configuration: Debug Win32 ------ 1> SortedList.cpp 1>c:\users\owner\documents\college\fall 2012\cs 368 - learn c++\program3\program3\sortedlist.cpp(159): error C2657: 'SortedList::*' found at the start of a statement (did you forget to specify a type?) 1>c:\users\owner\documents\college\fall 2012\cs 368 - learn c++\program3\program3\sortedlist.cpp(159): error C4430: missing type specifier - int assumed.

  • How to create "floating TextViews" in Android?

    - by Sotapanna
    Hi stackies, I'm programmatically putting various TextViews into a LinearLayout with a horizontal orientation. After 2h of research I couldn't find out how to tell Android not to squeeze all the TextViews in one line but instead to "float" non-fitting TextViews into the next line. I know there isn't something like actual "lines" in a LinearLayout, but how can I tell the TextViews to actually behave like floating DIVs from the HTML world? Thanks alot! Be well S.

  • Converting a C++ Checksum function to Java

    - by user1897599
    I'm trying to convert this C++ checksum to Java but for the time being I've failed. What am I doing wrong? What is it supposed to do? It is supposed to return a positive checksum for a buffer in OpenGL Here's the C part. DWORD QuickChecksum(DWORD *data, int size){ if(!data) { return 0x0; } DWORD sum; DWORD tmp; sum = *data; for(int i = 1; i < (size/4); i++) { tmp = data[i]; tmp = (DWORD)(sum >> 29) + tmp; tmp = (DWORD)(sum >> 17) + tmp; sum = (DWORD)(sum << 3) ^ tmp; } return sum; } And here is what I have tried in Java. As far As I know DWORD is 32bit so I use int in a long to get a unsigned int which should be done in java with ? I've been looking at this problem so much now that I've grown blind to it. public static long getChecksum(byte[] data, int size) { long sum, tmp; sum = getInt(new byte[]{data[0], data[1], data[2], data[3]},true) & 0xFF; for(int I = 4; I < data.length; I += 4) { tmp = getInt(new byte[]{data[I],data[I+1],data[I+2],data[I+3]},true) & 0xFF; tmp = (sum >>> 29) + tmp; tmp = (sum >>> 17) + tmp; sum = (sum << 3) ^ tmp; } return sum & 0xFF; } private static int getInt(byte[] bytes, boolean big) { ByteBuffer bb = ByteBuffer.wrap(bytes); return bb.getInt(); } Thank you all for your help!

  • Create a complex SQL query?

    - by mazzzzz
    Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max
