  • Looking for an automated logging tool/library for .NET!

    - by tsocks
    Hello, I'm looking for an library/tool for .NET that logs almost everything that happens in my C# application (Windows Form). The problem is that I'm delivering an application to a client (Windows XP) and after doing some task, that classic Microsoft error window appears: "ApplicationName has encountered a problem and needs to close. We are sorry for the inconvenience" I'm currently handling my application exceptions, but this is something external and I can't get anything from that error, so I would like any automated library that helps me with that. It would work if it logs each line of code executed, orr just log what line was executing before that error appeared, or something that could give me more info about that error. Thank you! P.S: It's a multithreaded application, and have to Timer controls (one for watching a folder every 5secs, and another for watching thread list...). I'm using Windows 7 here and everything seems to work ok.

  • Can I use Sikuli as an Jython library in my project?

    - by Yinan
    Sikuli is really cool, but it's working in its buildin Jython environment, the Sikuli IDE. So I m wondering is it possible to import Sikuli as an external library to my Jython library? I saw from Sikuli's website that they have this Python module which provides all Sikuli actions like click and type. Here is the link: http://sikuli.org/documentation.shtml#doc/pythondoc-python.edu.mit.csail.uid.Sikuli.html I have tried importing the skiuli-script.jar and add the skiuli-script/Lib to the PYTHONPATH. Then in my spike.py script, I try to do this: import python.edu.mit.csail.uid.Sikuli capture() #enter to screen capture mode then when execute the script, I got this error: java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no suitable image found. Did find: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no matching architecture in universal wrapper I m using Jython 2.2.1 and Mac 10.6.2 (32-bit mode). I have also set to use 32-bit mode first in Java Preference.

  • Do I need to use C3P0 pooling library in my (grails) web application?

    - by fabien7474
    Hi, I am not familiar at all with connection pooling library. I've just discovered it through this blog article) and I am not sure that I should use one in my web application based on grails/hibernate/mysql. So my question is simple : in which situations would you suggest to integrate a connection pooling library into a grails application? Always, Never or only over some connections threshold? P.S. : If you have ever used successfully C3P0 in your web application, I will greatly appreciate to hear your feedback (in terms of visible positive effects).

  • Good .NET library for fast streaming / batching trigonometry (Atan)?

    - by Sean
    I need to call Atan on millions of values per second. Is there a good library to perform this operation in batch very fast. For example, a library that streams the low level logic using something like SSE? I know that there is support for this in OpenCL, but I would prefer to do this operation on the CPU. The target machine might not support OpenCL. I also looked into using OpenCV, but it's accuracy for Atan angles is only ~0.3 degrees. I need accurate results.

  • Error appearing in application after updating cakePHP library files from 1.3.0 to 1.3.1

    - by Gaurav Sharma
    Hi everyone, I have just updated my cakephp library to latest version 1.3.1. Before this I was running v1.3.0 with no errors. After running the application I am given this error message. unserialize() [function.unserialize]: Error at offset 0 of 2574 bytes [CORE\cake\libs\cache\file.php, line 176] I updated the libraries simply by replacing the existing cake files with the new ones downloaded from the net. Is it the correct way of updating applications. I did'nt made any customizations to the core library of cakePHP. What is the problem ? Please help. Thanks

  • Can I use Visual Studio 2010's C++ compiler with Visual Studio 2008's C++ Runtime Library?

    - by BillyONeal
    I have an application that needs to operate on Windows 2000. I'd also like to use Visual Studio 2010 (mainly because of the change in the definition of the auto keyword). However, I'm in a bit of a bind because I need the app to be able to operate on older OS's, namely: Windows 2000 Windows XP RTM Windows XP SP1 Visual Studio 2010's runtime library depends on the EncodePointer / DecodePointer API which was introduced in Windows XP SP2. If using the alternate runtime library is possible, will this break code that relies on C++0x features added in VS2010, like std::regex?

  • Do I have to create a static library to test my application?

    - by Christopher Gateley
    I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

  • 47 memory leaks. STL pointers.

    - by icelated
    I have a major amount of memory leaks. I know that the Sets have pointers and i cannot change that! I cannot change anything, but clean up the mess i have... I am creating memory with new in just about every function to add information to the sets. I have a Cd/ DVD/book: super classes of ITEM class and a library class.. In the library class i have 2 functions for cleaning up the sets.. Also, the CD, DVD, book destructors are not being called.. here is my potential leaks.. library.h #pragma once #include <ostream> #include <map> #include <set> #include <string> #include "Item.h" using namespace std; typedef set<Item*> ItemSet; typedef map<string,Item*> ItemMap; typedef map<string,ItemSet*> ItemSetMap; class Library { public: // general functions void addKeywordForItem(const Item* const item, const string& keyword); const ItemSet* itemsForKeyword(const string& keyword) const; void printItem(ostream& out, const Item* const item) const; // book-related functions const Item* addBook(const string& title, const string& author, int const nPages); const ItemSet* booksByAuthor(const string& author) const; const ItemSet* books() const; // music-related functions const Item* addMusicCD(const string& title, const string& band, const int nSongs); void addBandMember(const Item* const musicCD, const string& member); const ItemSet* musicByBand(const string& band) const; const ItemSet* musicByMusician(const string& musician) const; const ItemSet* musicCDs() const; // movie-related functions const Item* addMovieDVD(const string& title, const string& director, const int nScenes); void addCastMember(const Item* const movie, const string& member); const ItemSet* moviesByDirector(const string& director) const; const ItemSet* moviesByActor(const string& actor) const; const ItemSet* movies() const; ~Library(); void Purge(ItemSet &set); void Purge(ItemSetMap &map); }; here is some functions for adding info using new in library. Keep in mind i am cutting out alot of code to keep this post short. library.cpp #include "Library.h" #include "book.h" #include "cd.h" #include "dvd.h" #include <iostream> // general functions ItemSet allBooks; ItemSet allCDS; ItemSet allDVDs; ItemSetMap allBooksByAuthor; ItemSetMap allmoviesByDirector; ItemSetMap allmoviesByActor; ItemSetMap allMusicByBand; ItemSetMap allMusicByMusician; const ItemSet* Library::itemsForKeyword(const string& keyword) const { const StringSet* kw; ItemSet* obj = new ItemSet(); return obj; const Item* Library::addBook(const string& title, const string& author, const int nPages) { ItemSet* obj = new ItemSet(); Book* item = new Book(title,author,nPages); allBooks.insert(item); // add to set of all books obj->insert(item); return item; const Item* Library::addMusicCD(const string& title, const string& band, const int nSongs) { ItemSet* obj = new ItemSet(); CD* item = new CD(title,band,nSongs); return item; void Library::addBandMember(const Item* musicCD, const string& member) { ItemSet* obj = new ItemSet(); (((CD*) musicCD)->addBandMember(member)); obj->insert((CD*) musicCD); here is the library destructor..... Library::~Library() { Purge(allBooks); Purge(allCDS); Purge(allDVDs); Purge(allBooksByAuthor); Purge(allmoviesByDirector); Purge(allmoviesByActor); Purge(allMusicByBand); Purge(allMusicByMusician); } void Library::Purge(ItemSet &set) { for (ItemSet::iterator it = set.begin(); it != set.end(); ++it) delete *it; set.clear(); } void Library::Purge(ItemSetMap &map) { for (ItemSetMap::iterator it = map.begin(); it != map.end(); ++it) delete it->second; map.clear(); } so, basically item, cd, dvd class all have a set like this: typedef set<string> StringSet; class CD : public Item StringSet* music; and i am deleting it like: but those superclasses are not being called.. Item destructor is. CD::~CD() { delete music; } Do, i need a copy constructor? and how do i delete those objects i am creating in the library class? and how can i get the cd,dvd, destructor called? would the addbandmember function located in the library.cpp cause me to have a copy constructor? Any real help you can provide me to help me clean up this mess instead of telling me not to use pointers in my sets i would really appreciate. How can i delete the memory i am creating in those functions? I cannot delete them in the function!!

  • How do people manage changes to common library files stored across mutiple (Mercurial) repositories?

    - by mckoss
    This is perhaps not a question unique to Mercurial, but that's the SCM that I've been using most lately. I work on multiple projects and tend to copy source code for libraries or utilities from a previous project to get a leg up on starting a new project. The problem comes in when I want to merge all the changes I made in my latest project, back into a "master" copy of those shared library files. Since the files stored in disjoint repositories will have distinct version histories, Mercurial won't be able to perform an intelligent merge if I just copy the files back to the master repo (or even between two independent projects). I'm looking for an easy way to preserve the change history so I can merge library files back to the master with a minimum of external record keeping (which is one of the reasons I'm using SVN less as merges require remembering when copies were made across branches). Perhaps I need to do a bit more up-front organization of my repository to prepare for a future merge back to a common master.

  • c# hierarchy collection library? - anyone know of one (e.g. GetDirectChildren, GetAllChildren, GetPa

    - by Greg
    Hi, Does anyone know of a solid C# library / approach to manage a hierarchy/web type collection? This would be a library that would basic consist of the concept of nodes & relationships, for example to model web pages/files linked under a URL, or modeling IT infrastructure. It would have key methods such as: Node.GetDirectParents() Node.GetRootParents() Node.GetDirectChildren() Node.GetAllChildren() So it's smarts would include the ability to "walk the tree" of nodes based on the relationships when someone does ask for "give me all the children under this node" for example. It ideally include a persistence layer, to save/retrieve such data to/from a databases (e.g. with a Nodes and Relationships table). Thanks

  • How can I upload a file to a Sharepoint Document Library using Silverlight and client web-services?

    - by pclem12
    Most of the solutions I've come across for Sharepoint doc library uploads use the HTTP "PUT" method, but I'm having trouble finding a way to do this in Silverlight because it has restrictions on the HTTP Methods. I visited this http://msdn.microsoft.com/en-us/library/dd920295(VS.95).aspx to see how to allow PUT in my code, but I can't find how that helps you use an HTTP "PUT". I am using client web-services, so that limits some of the Sharepoint functions available. That leaves me with these questions: Can I do an http PUT in Silverlight? If I can't or there is another better way to upload a file, what is it? Thanks

  • What is the most mature library to render equirectangular images in Flash?

    - by Dave Viner
    I have a series of equirectangular images. I'd like to display them in a custom Flash player so that the user could see the spherical nature of the images, and "look up", "look down", "look left/right" (or pan, zoom, etc). (Note that I have a long series of images, so the library must allow for dynamic loading of the images themselves, rather than having the images "baked" into the SWF player.) What is the best library to manage the display of the equirectangular images in Flash? By "best", I mean the most mature, most reliable, most robust, and fastest performing. For reference, an example of an equirectangular image can be found at http://archive.bigben.id.au/tutorials/360/background/projections.html.

  • access EF classes from a Class Library - exactly how do configure/test the connection string in the

    - by Greg
    Hi, I'm getting very confused about how to call my EF classes in a Class Library from the Client Project I have? Things worked fine when they were in the same project. Now I'm getting errors such as "Unable to load the specified metadata resource ". I've see various ideas / suggestions re how to fix the connection string (e.g. create an App.config in your client project & copy the connection string config from your class library, something about change the connection settings to copy to output, etc) QUESTION - Can someone provide a solid way on how to get EF class access from a separate project working? (i.e. how to get the correct connection information to the client somehow) thanks

  • Where can I find "reference barcodes" to verify barcode library output?

    - by mjustin
    This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

  • input URL, output contents of "view page source", i.e. after javascript / etc, library or command-li

    - by Ryan Berckmans
    I need a scalable, automated, method of dumping the contents of "view page source" (DOM) to a file. Programs such as wget or curl will non-interactively retrieve a set of URLs, but do not execute javascript or any of that 'fancy stuff'. My ideal solution looks like any of the following (fantasy solutions): cat urls.txt | google-chrome --quiet --no-gui \ --output-sources-directory=~/urls-source (fantasy command line, no idea if flags like these exist) or cat urls.txt | python -c "import some-library; \ ... use some-library to process urls.txt ; output sources to ~/urls-source" As a secondary concern, I also need: dump all included javascript source to file (a la firebug) dump pdf/image of page to file (print to file)

  • How do I properly register the Type Library of A VB.NET COM+ Component?

    - by k_Dank
    I am looking to upgrade legacy VB6 COM+ components to VB.NET components. I have seemingly upgraded one already, called EventPackage, which has one class, IEventListener. Another, TradeOrders, Implements EventPackage.IEventListener. When attempting to build TradeOrders, I get the following Errors/Warnings; Cannot load type library for reference "EventPackage". Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)) The referenced component 'EventPackage' could not be found. Type 'EventPackage.IEventListener' is not defined. In the .vbproj, I notice this reference <COMReference Include="EventPackage"> <Guid>{0D76C094-21A6-4E04-802B-6E539F7102D7}</Guid> <Lcid>0</Lcid> <VersionMajor>2</VersionMajor> <VersionMinor>0</VersionMinor> <WrapperTool>tlbimp</WrapperTool> </COMReference> When I search the registry for this Guid, I find nothing. When using GUIDs for similar COM+ objects, I find them in HKEY_CLASSES_ROOT\CLSID\{...}\TypeLib ("..." being the GUID of the other component). When I go to the registry key name corresponding to EventPackage.IEventListener, I find that there is no \TypeLib subkey. As you might suspect, searching the reg for "0D76C094-21A6-4E04-802B-6E539F7102D7" yields no results. So I know this must be a registry problem, But I have tried seemingly every google result I have found. I have tried Regasm and regsvcs .exe's to no avail. Many pages just tell me that dragging the dll to the COM+ manager should automatically register the component. So how do I register the Type library? Details on how I made EventPackage COM+ component Ran the VB6-VB.NET wizard Then I added some lines to the assemblyinfo.vb file added Imports System.EnterpriseServices added Imports System.EnterpriseServices Imports System.Data.SqlClient <Assembly: CLSCompliant(True)> <Assembly: AssemblyKeyFileAttribute("...")> for a strong name <Assembly: Guid("...")> (Where "..." is the COM+ CLSID of the old component) I added the following to the class file IEventListener.VB Imports System.EnterpriseServices <ComClass("...")> _ (Where ... is the proper COM+ CLSID, that is the only argument) Inherits ServicedComponent changed the ID made by the Conversion wizard to the proper value (from <System.Runtime.InteropServices.ProgId("IEventListener_NET.IEventListener)> to <System.Runtime.InteropServices.ProgId("EventPackage.IEventListener")> _ Then I dragged the DLL into the COM+ manager in the proper COM+ application (although, the "Path" is not specified and only says mscoree.dll)
