  • Installing assemblies to GAC with Windows Installer

    - by Andy Xufuris
    I am creating a Windwos Installer project just for the use of installing our third party assemblies into the gac of the users computer. The problem i am running into, is when i make an update to the assemblie and increment it's version number, i get an error saying: "Another version of this product is already installed. Installation of this version cannot continue..." I would have figured that windows installer would update the local machine with the new assemblie. Am i doing something wrong?

  • Why .NET does not allow cross-thread operations?

    - by RHaguiuda
    This question is not about what is a cross-thread operation, and how to avoid it, but why internal mechanics of .NET framework does not allow a cross-thread operation. I can`t understand why a SerialPort DataReceived event cannot update a simple text box on my form and why using delegates this is possible?

  • Finding partial substrings within a string

    - by Peter Chang
    I have two strings which must be compared for similarity. The algorithm must be designed to find the maximal similarity. In this instance, the ordering matters, but intervening (or missing) characters do not. Edit distance cannot be used in this case for various reasons. The situation is basically as follows: string 1: ABCDEFG string 2: AFENBCDGRDLFG the resulting algorithm would find the substrings A, BCD, FG I currently have a recursive solution, but because this must be run on massive amounts of data, any improvements would be greatly appreciated

  • Does mercurial-server support subrepo?

    - by Esteban Feldman
    I installed mercurial-server on one of my machines, cloned my project there, it has 3 subrepos, and when I try to clone it back to another location I get an error: remote: mercurial-server: Cannot create repo under existing repo abort: no suitable response from remote hg! So I'm starting to think that mercurial-server doesn't handle subrepo. Any clue?

  • How to migrate the Access database to MOSS 2007 sql server with the use of SSMA (sql server migratio

    - by pointlesspolitics
    Hi, One of my friends got the access database with Forms (VBA) and wish to migrate all the database table to the newly installed MOSS 2007 site. He is using SSMI for this purpose. He cannot do it because there are plenty of errors and warnings. I think it is due to the old Access queries. Is there any other way to import the database to sql 2005 from access ? Thanks

  • Good style for handling constructor failure of critical object

    - by mtlphil
    I'm trying to decide between two ways of instantiating an object & handling any constructor exceptions for an object that is critical to my program, i.e. if construction fails the program can't continue. I have a class SimpleMIDIOut that wraps basic Win32 MIDI functions. It will open a MIDI device in the constructor and close it in the destructor. It will throw an exception inherited from std::exception in the constructor if the MIDI device cannot be opened. Which of the following ways of catching constructor exceptions for this object would be more in line with C++ best practices Method 1 - Stack allocated object, only in scope inside try block #include <iostream> #include "simplemidiout.h" int main() { try { SimpleMIDIOut myOut; //constructor will throw if MIDI device cannot be opened myOut.PlayNote(60,100); //..... //myOut goes out of scope outside this block //so basically the whole program has to be inside //this block. //On the plus side, it's on the stack so //destructor that handles object cleanup //is called automatically, more inline with RAII idiom? } catch(const std::exception& e) { std::cout << e.what() << std::endl; std::cin.ignore(); return 1; } std::cin.ignore(); return 0; } Method 2 - Pointer to object, heap allocated, nicer structured code? #include <iostream> #include "simplemidiout.h" int main() { SimpleMIDIOut *myOut; try { myOut = new SimpleMIDIOut(); } catch(const std::exception& e) { std::cout << e.what() << std::endl; delete myOut; return 1; } myOut->PlayNote(60,100); std::cin.ignore(); delete myOut; return 0; } I like the look of the code in Method 2 better, don't have to jam my whole program into a try block, but Method 1 creates the object on the stack so C++ manages the object's life time, which is more in tune with RAII philosophy isn't it? I'm still a novice at this so any feedback on the above is much appreciated. If there's an even better way to check for/handle constructor failure in a siatuation like this please let me know.

  • Where in an Eclipse workspace is the list of projects stored?

    - by Kris Pruden
    I use eclipse with "external" projects - i.e. projects created from existing source. Poking around in the workspace files, I cannot find any reference to these projects. My question is: how does eclipse keep track of these projects? I'd like to be able to add such a project to the workspace automatically (by generating .project and .classpath files)..

  • SQL Server 2008 BIDS without the Database Engine

    - by Gareth Hill
    Does anyone know how we can install BIDS for SQL Server 2008 without having to install the Database Engine? With the SQL Server 2008 Express install it appears to be mandatory to install the Database Engine when all we would like the end users to have access to is BIDS to develop their RDL's to deploy to an existing SSRS instance? It looks like BIDS 2005 was available as a standalone download - the toolkit - however I cannot find anything similar for 2008.

    I cannot understand why this throws undefined reference to `floor'": double curr_time = (double)time(NULL); return floor(curr_time); Hasn't it been casted to double, which is what floor receives?

  • Send an onclick to a dropdown list

    - by P Nelson
    Is it possible to show the list of items in a dropdown list when the user presses the up or down arrow keys, when focus is on that dropdown control? I think this would involve sending an onclick to the dropdown list using onkeydown for Keycode 38(arrow up) & 40(arrow down)? But I cannot figure out how to do this.

  • many-to-many performance concerns with fluent nhibernate.

    - by Ciel
    I have a situation where I have several many-to-many associations. In the upwards of 12 to 15. Reading around I've seen that it's generally believed that many-to-many associations are not 'typical', yet they are the only way I have been able to create the associations appropriate for my case, so I'm not sure how to optimize any further. Here is my basic scenario. class Page { IList<Tag> Tags { get; set; } IList<Modification> Modifications { get; set; } IList<Aspect> Aspects { get; set; } } This is one of my 'core' classes, and coincidentally one of my core tables. Virtually half of the objects in my code can have an IList<Page>, and some of them have IList<T> where T has its own IList<Page>. As you can see, from an object oriented standpoint, this is not really a problem. But from a database standpoint this begins to introduce a lot of junction tables. So far it has worked fine for me, but I am wondering if anyone has any ideas on how I could improve on this structure. I've spent a long time thinking and in order to achieve the appropriate level of association required, I cannot think of any way to improve it. The only thing I have come up with is to make intermediate classes for each object that has an IList<Page>, but that doesn't really do anything that the HasManyToMany does not already do except introduce another class. It does not extend the functionality and, from what I can tell, it does not improve performance. Any thoughts? I am also concerned about Primary Key limits in this scenario. Most everything needs to be able to have these properties, but the Pages cannot be unique to each object, because they are going to be frequently shared and joined between multiple objects. All relationships are one-sided. (That is, a Page has no knowledge of what owns it). Because of this, I also have no Inverse() mapped HasManyToMany collections. Also, I have read the similar question : Usage of ORMs like NHibernate when there are many associations - performance concerns But it really did not answer my concerns.

  • OCCI createEnvironment Blocks My Thread

    - by sahs
    Hello, I'm writing a multi-threaded application, where there is a main thread which distributes tasks to the worker threads. According to the task, a worker thread creates a connection, by using a global occi environment. When a worker thread completes its task, it closes the connection (I'm sure, there is no exception thrown while termination). My problem is that after a while(sometimes 5 mins, sometimes 5 hours) the threads cannot get connection from the environment, and they get blocked there. What can be the problem?

I understand that I make a function to do so and I have one...but all it does right now is strip tags... am I doomed to use replace? or is there a way i can just remove all special characters and spaces and limit it to only letters and numbers...then as for the password limit it to only letters and numbers exclimation points, periods, and other special chars that cannot affect my SQL query. Please help :/ Thanks, Matt

  • What are the limitations of a STA thread in compare to MTA threads ?

    - by Xaqron
    If we make a thread STA like this: Thread.SetApartmentState(STA); then it cannot run code marked with [MTAThread] attribute. We have seen [STAThread] in windows and console applications but I have never seen code with [MTAThread] attribute and don't know which .NET libraries use this attribute. My question is what are the limitations of a thread with apartment state set to STA, in compare to threads with MTA apartment state (natural .NET threads) ?
