  • check if sqlserver is installed on a machine thro C#

    - by Skun
    Hey ! I am making an application which is a user interface to access 2 types of databases - SQLite and MSSQL server. The thing is, SQLite doesnt need to be "installed" since its just a flatfile database, but on the other hand, SQLserver (Express/normal) need to be installed before use. My Question is simple: Is there a way by which i can find out if an instance of SQLserver has been installed on the local machine by using a C# program?

  • binlog_format = STATEMENT and CURRENT_TIMESTAMP with MySQL replication

    - by xma
    Hi, can a MySQL slave instance have different row values for the same ID when binlog_format is set to STATEMENT and we insert something like: insert into foo values(CURRENT_TIMESTAMP) As I understand it, the slave read the SQL statement and execute it thus, if the replication is lagging, could lead to differences for the same row. Right or wrong ? How can I avoid this situation ? Thank you.

  • how can protected members of base class be accessed during unit test?

    - by amateur
    I am creating a unit test in mstest with rhino mocks. I have a class A that inherits class B. I am testing class A and create an instance of it for my test. The class it inherits, "B", has some protected methods and protected properties that I would like to access for the benefit of my tests. For example, validate that a protected property on my base class has the expected value. Any ideas how I might access these protected properties of class B during my test?

  • Extending a Java Swing class in Clojure

    - by mikera
    I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods. I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances. What's the recommended way of doing this?

  • Convert user input into ToString() method inside FlowDocument in Workflow 4.0

    - by Jon Ownbey
    I have a Workflow 4.0 app that generates emails. In a dialog for creating the email body the user needs to be able to input some string value representing an existing wf instance variable to be inserted as a string at runtime. So they input something like: Email body text including <. (say ExistingVariable is an int or something like that) Any helpful hints for how to convert this text with a ToString() at runtime?

  • What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

    - by Josh Schwartzman
    I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)

  • How do I get intellisense to pop up?

    - by TheLearner
    How do I get intellisense to pop up while I am coding? I know it pops up when I start typing a known type e.g.: if I type NSS it will finish it for me NSString. How do I get it to give me a bunch of options like in Visual Studio e.g.: if I type NS I want to see what my options are like NSString, NSInteger etc? And if I have not typed anything I still want a bunch of options like all the instance variables etc.

  • Using mod_negotiation to serve webp if the UA requests it.

    - by Rich Bradshaw
    Is it possible to use mod_negotiation to serve up a webp image if the browser supports it, and a jpg otherwise? For instance, if I link to an image with the path /images/test, it serves the image found at /images/test.webp if the UA knows about webp, or jpg otherwise? I've tried poking around, but it seems that the Accept headers in Chrome at least look like Accept:*/*, rather than specifying the image type. If this isn't the way to do it, has anyone got any other suggestions?

  • Can I use php's fwrite with 644 file permissions?

    - by filip
    I am trying to set up automated .htaccess updating. This clearly needs to be as secure as possible, however right now the best I can do file permission-wise is 666. What can I do to setup either my server or php code so that my script's fwrite() command will work with 644 or better? For instance is there a way to set my script(s) to run as owner?

  • Activerecord default accessors & unusual requirements

    - by JP
    I have an ActiveRecord::Base class which needs to have a field that is automatically generated when a new instance is made. How should I go about doing this? By defining an initialize function? class Thing < ActiveRecord::Base # 'special' (integer) needs to be set to lowest unused number (above 0) # considering that random rows will be removed via other processes end This is as far as I've got! Any ideas?

  • At what point in the render process of a web page can we interact with that page

    - by Bamerza
    I'd like to measure to distinct user experience points during the rendering of an HTML page: 1) Point which user sees the first painting of the page 2) Point at which user can interact with the page - meaning sees 75% of it or can actually register a button click or link click I am pretty certain these UX interactions can start before the HTML code is fully rendered, so would that instance be the JS func "OnLoad" or some other distinct measureable value/function? If it helps, we can even narrow the answer down to webkit based browsers.

  • How to get an array size

    I'd like to know how to get an array rows & columns size. For instance it would be something like this: int matrix[][] = { { 2, 3 , 4}, { 1, 5, 3 } } The size of this one would be 2 x 3. How can I calculate this without including other libraries but stdio or stdlib?

  • Methods in Ruby: objects or not?

    - by Mladen Jablanovic
    Inspired by this discussion, after some googling I wasn't able to find an answer to a pretty simple question regarding methods in Ruby: are they objects or not? There are different opinions here and there, and I would really like to hear, let's say, an in-depth explanation. I'm aware of Object#method method, which takes a method name and returns a Method instance, but, on the other hand, there's a similar thing you can do with blocks to make them into Proc instances, and blocks aren't objects, so what makes methods any different?

  • Java, user input to the command line when using Runtime.getRuntime().exec(command);

    - by user1557354
    I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

  • vector does not erase content correctly (infite amount run of copy asignment operator untill crash [BEX])?

    - by Gam Erix
    Well my problem is that after I want to "unload" loaded DLL's the copy assignmnent operator is called an unlimited amount of times until crash. The code from which I remove the vector data looks like this: void UnloadPlugins() { dbg(("[DBG]UnloadPlugins()")); for(std::vector<DLLInfo>::iterator it = plugins.begin(); it != plugins.end(); ++it) { plugins.erase(it); } dbg(("[DBG]UnloadPlugins()::Done")); } however "[DBG]UnloadPlugins()::Done" gets never printed. this is my copy assignmnent operator: // 2. copy assignment operator DLLInfo& operator=(const DLLInfo& that) { dbg(("[DBG]Start-DLLInfo& operator=(const DLLInfo& that)")); Instance = that.Instance;//hinstance dbg(("[DBG]DLLInfo 1")); //Identifier.assign(that.Identifier);//string dbg(("[DBG]DLLInfo 2")); IsAMX = that.IsAMX;//integer dbg(("[DBG]DLLInfo 3")); dwSupportFlags = that.dwSupportFlags;//integer dbg(("[DBG]DLLInfo 4")); Load = that.Load;//integer dbg(("[DBG]DLLInfo 5")); Unload = that.Unload;//integer dbg(("[DBG]DLLInfo 6")); Supports = that.Supports;//integer dbg(("[DBG]DLLInfo 7")); ProcessTick = that.ProcessTick;//integer dbg(("[DBG]DLLInfo 8")); AmxLoad = that.AmxLoad;//integer dbg(("[DBG]DLLInfo 9")); AmxUnload = that.AmxUnload;//integer dbg(("[DBG]DLLInfo 10")); UseDestructor = that.UseDestructor;//bool dbg(("[DBG]DLLInfo 11")); KeyboardHit = that.KeyboardHit;//integer dbg(("[DBG]End-DLLInfo& operator=(const DLLInfo& that)")); return *this; } So the log looks like: [17:50:50] [DBG]UnloadPlugins() [17:50:50] [DBG]~DLLInfo [17:50:50] [DBG]~DLLInfo::if(this->UseDestructor) passed [17:50:50] [DBG]~DLLInfo::if(this->UseDestructor)::if(this->Unload != NULL && this->IsAMX) passed [17:50:50] [DBG]~DLLInfo::end [17:50:50] [DBG]Start-DLLInfo& operator=(const DLLInfo& that) [17:50:50] [DBG]DLLInfo 1 [17:50:50] [DBG]DLLInfo 2 [17:50:50] [DBG]DLLInfo 3 [17:50:50] [DBG]DLLInfo 4 [17:50:50] [DBG]DLLInfo 5 [17:50:50] [DBG]DLLInfo 6 [17:50:50] [DBG]DLLInfo 7 [17:50:50] [DBG]DLLInfo 8 [17:50:50] [DBG]DLLInfo 9 [17:50:50] [DBG]DLLInfo 10 [17:50:50] [DBG]DLLInfo 11 [17:50:50] [DBG]End-DLLInfo& operator=(const DLLInfo& that) [17:50:50] [DBG]Start-DLLInfo& operator=(const DLLInfo& that) ... [17:50:50] [DBG]End-DLLInfo& operator=(const DLLInfo& that) ...repeat until crash What could the problem be?

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.
