• Java Save Object to File

  - by Kristian Matthews

  I've tried implementing various methods from around the internet, all seem to be providing the same solution. But it just won't work and I'm unsure why, it creates the file, however, it's blank and if I try loading that file, it has an error. Main.java contains the code to save and load the file: 190-224. Rooms.java contains the object. Code Any help is greatly appreciated, I've been trying for almost a week now! Thanks in advanced!

• delete,copy,rename files and directories in WINAPI ..?

  - by Kristian

  hi I made a code that search in a givin path for a certain file name or folder and print the value BUT now how can i modify it to instead of printing its name perform on of the operations ( delete,copy,rename ) I searched on google and found nothin. #include "stdafx.h" #include <windows.h> int _tmain(int argc, _TCHAR* argv[]) { TCHAR *fn; fn=L"d:\\*"; HANDLE f; WIN32_FIND_DATA data; f=FindFirstFile(fn,&data); if(f==INVALID_HANDLE_VALUE){ printf("not found\n"); return 0; } else{ _tprintf(L"found this file: %s\n",data.cFileName); } while(FindNextFile(f,&data)){ { _tprintf(L"found this file: %s\n",data.cFileName); } } } FindClose(f); return 0; }

• LINQ - joining multiple lists

  - by kristian

  I've looked at the 101 Linq Samples here but I can't see anything like this in that list. If I'm just not seeing a relevant example there, please link to it. If I have these 3 classes: class Student { int id; string name } class Course { int id, string name } class Enrolment { int studentId; int courseId; } How would I use LINQ to get a list of courses a student is enrolled on? (assume I have an IList of all three classes)

• .net - invoke methods from classes from a certain namespace via reflection

  - by Kristian Hildebrandt

  SPL and PHP allows you to create objects on the fly from classes, that fulfill certain conditions, such as implementing certain interfaces and stuff like that. However, I would like to do something similar in c# and automatically create objects from all classes in a namespace and invoke a particular method from those classes that implement a certain interface. My experience developing desktop apps is very limited. I am not quite sure if I should use delegates to archive this or if reflection is really the way to go.

• Encrypting a file in win API

  - by Kristian

  hi I have to write a windows api code that encrypts a file by adding three to each character. so I wrote this now its not doing anything ... where i go wronge #include "stdafx.h" #include <windows.h> int _tmain(int argc, _TCHAR* argv[]) { HANDLE filein,fileout; filein=CreateFile (L"d:\\test.txt",GENERIC_READ,0,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL); fileout=CreateFile (L"d:\\test.txt",GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL); DWORD really; //later this will be used to store how many bytes I succeed to read do { BYTE x[1024]; //the buffer the thing Im using to read in ReadFile(filein,x,1024,&really,NULL); for(int i=0 ; i<really ; i++) { x[i]= (x[i]+3) % 256; } DWORD really2; WriteFile(fileout,x,really,&really2,NULL); }while(really==1024); CloseHandle(filein); CloseHandle(fileout); return 0; } and if Im right how can i know its ok

• Custom deleters for std::shared_ptrs

  - by Kristian D'Amato

  Is it possible to use a custom deleter after creating a std::shared_ptr without using new? My problem is that object creation is handled by a factory class and its constructors & destructors are protected, which gives a compile error, and I don't want to use new because of its drawbacks. To elaborate: I prefer to create shared pointers like this, which doesn't let you set a custom deleter (I think): auto sp1 = make_shared<Song>(L"The Beatles", L"Im Happy Just to Dance With You"); Or I can create them like this, which does let met set a deleter through an argument: auto sp2(new Song, MyDeleterFunc); But the second one uses new, which AFAIK isn't as efficient as the top sort of allocation. Maybe this is clearer: is it possible to get the benefits of make_shared<> as well as a custom deleter? Would that mean having to write an allocator?

• How do I search for an array of values in a many to many relation?

  - by Kristian Gudal

  Hey I have a problem with my LINQ to Entity model many to mant relation. I am new to both C# and LINQ, so bear with me. I have a model containing pictures and tags, where each picture can have many tags, and each tag can be on many pictures. In the db there is a normal relation table, but in the object model I see it as picture.tags (as a list) and tag.pictures (as a list). A search query contains several tags, and the result of the search is to contain all pictures that are tagged with all the tags (but maybe more) I have searched for. The number of tags to search for is not fixed. How can this best be done?

• MatLab plot part of surface

  - by Kristian

  Say I have the following script: u = -5:.2:5; [X,Y] = meshgrid(u, u); Z = cos(X).*cos(Y).*exp(-sqrt(X.^2 + Y.^2)/4); surf(X,Y,Z); Is there anyway that I can make MatLab plot only parts of the surface? Say, for instance, I just want to plot a single point, or a single grid, what can I do? I thought perhaps to plot a single point I could use: surf(X(1,1), Y(1,1), Z(1,1)) But then I get the error message: ??? Error using ==> surf at 78 Data dimensions must agree. I would really appreciate some input/help here. Thanks in advance :)

• 2-legged OAuth and the Gmail atom feed

  - by jdcotter

  We're trying to get 2-legged OAuth to work with the Gmail atom feed. We're using the Java library contributed by John Kristian, Praveen Alavilli and Dirk Balfanz. [http://oauth.net/code/] instead of the GData library. We know we have the correct CONSUMER_KEY and CONSUMER_SECRET, etc. becuase it works with the Contacts feed (http://www.google.com/m8/feeds/contacts/default/full) and have no problems. However with Gmail atom feed it always returns: HTTP/1.1 401 Unauthorized Any ideas? Should we try a different OAuth framework or does the problem lie on the Google side?

• Running router as virtual machine, can it be realible ?

  - by Kr1stian

  Hi all Does anyone here run their routing through virtual machine, have virtual machine setup as main router/getaway etc ? If yes, how many clients are using this kind of setup ? For those who are wondering why I'm asking this. I got assignment for my internship to create all in one "box" which would do routing and be IP PBX in one time ( only open source solutions can be used, expect RouterOS). The routing part is currently done through RouterOS and for VoIP they want to use sipXecs. RouterOS supports virtualization through KVM, but RouterOS itself only supports 2GB of memory ( and wont support more in near future). sipXecs needs allot more than 2GB. I told them that we could solve this problem by putting RouterOS as virtual machine to 64bit hostOS ( e.g. CentOS), and other virtual machine would run sipXecs. By that we would be able to use whole memory. But they told me that it's to risky to do something like that and that they need something with "enterprise stability/reliability". I told them that we could make redundant image of each VM which would automatically start if one VM stop's working, but I was told the same thing. So this is why I asked those question above, to see if I really suggested something that's not good to do, or maybe this is something completely normal and it can be done with "enterprise stability/reliability" :) Thank you for answers, Kristian
