• How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

  - by peace

  I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

• Modifying annotation attribute value at runtime in java

  - by Lici

  Hi folks: some methods in our model pojos have been annotated like this: @Column(name="cli_clipping_id", updatable=false, columnDefinition = "varchar(" + ModelUtils.ID_LENGTH + ") COLLATE utf8_bin") columnDefinition attribute is database vendor dependant, so when trying to drop schema in HSQLDB using Hibernate it fails: [ERROR] 16 jun 12:58:42.480 PM main [org.hibernate.tool.hbm2ddl.SchemaExport] Unexpected token: COLLATE in statement [create table cms.edi_editorial_obj (edi_uuid varchar(23) COLLATE ] To fix this, i'm thinking on this solution (but don't want to spend time if it isn't possible) , at runtime, for each method column annotated: Get @Column annotation Create a copy of the column annotation, setting columnDefinition null using javaassist. set column method annotation to the copy column annotation object overriding the old one (i don't know it this is possible) Is it possible to "hack" these methods this way? Any help would be much appreciated ...

• Maintaining a common set of Eclipse preferences

  - by Robert Munteanu

  Whenever I switch workspaces/Eclipse installs I need to copy/redo the preferences: compiler settings; font sizes/families; code formatter; java code templates; editor templates; code clean-ups; I would like to maintain these settings in an unitary way, preferrably under source control. How can I do that? I know about 'copy settings' when creating a new workspace, but it does not keep updated copies.

• Homemade fstat to get file size, always return 0 length.

  - by Fred

  Hello, I am trying to use my own function to get the file size from a file. I'll use this to allocate memory for a data structure to hold the information on the file. The file size function looks like this: long fileSize(FILE *fp){ long start; fflush(fp); rewind(fp); start = ftell(fp); return (fseek(fp, 0L, SEEK_END) - start); } Any ideas what I'm doing wrong here?

• Set database based on how the application was started

  - by AaronThomson

  I have two Rails applications (lets call them APP-1 and APP-2), each of them has a dependancy on a third Rails application (APP-3). I would like to be able to run the tests for APP-1 and APP-2 in parallel on my CI server. The problem is, both need to start up APP-3 and write to a DB via the APP-3. This causes conflicts and failures if the tests are run in parallel. My idea for a solution is for APP-1 and APP-2 to each start their own instance of APP-3 and to have each instance point to a different DB. Is there a way to dynamically set the DB in the database.yml of APP-3 so that it connects to a different DB depending on which APP starts it up? FYI. APP-1 and APP-2 currently start APP-3 via rake tasks.

• Output from OouraFFT correct sometimes but completely false other times. Why ?

  - by Yan

  Hi I am using Ooura FFT to compute the FFT of the accelerometer data in windows of 1024 samples. The code works fine, but then for some reason it produces very strange outputs, i.e. continuous spectrum with amplitudes of the order of 10^200. Here is the code: OouraFFT *myFFT=[[OouraFFT alloc] initForSignalsOfLength:1024 NumWindows:10]; // had to allocate it UIAcceleration *tempAccel = nil; double *input=(double *)malloc(1024 * sizeof(double)); double *frequency=(double *)malloc(1024*sizeof(double)); if (input) { //NSLog(@"%d",[array count]); for (int u=0; u<[array count]; u++) { tempAccel = (UIAcceleration *)[array objectAtIndex:u]; input[u]=tempAccel.z; //NSLog(@"%g",input[u]); } } myFFT.inputData=input; // specifies input data to myFFT [myFFT calculateWelchPeriodogramWithNewSignalSegment]; // calculates FFT for (int i=0;i<myFFT.dataLength;i++) // loop to copy output of myFFT, length of spectrumData is half of input data, so copy twice { if (i<myFFT.numFrequencies) { frequency[i]=myFFT.spectrumData[i]; // } else { frequency[i]=myFFT.spectrumData[myFFT.dataLength-i]; // copy twice } } for (int i=0;i<[array count];i++) { TransformedAcceleration *NewAcceleration=[[TransformedAcceleration alloc]init]; tempAccel=(UIAcceleration*)[array objectAtIndex:i]; NewAcceleration.timestamp=tempAccel.timestamp; NewAcceleration.x=tempAccel.x; NewAcceleration.y=tempAccel.z; NewAcceleration.z=frequency[i]; [newcurrentarray addObject:NewAcceleration]; // this does not work //[self replaceAcceleration:NewAcceleration]; //[NewAcceleration release]; [NewAcceleration release]; } TransformedAcceleration *a=nil;//[[TransformedAcceleration alloc]init]; // object containing fft of x,y,z accelerations for(int i=0; i<[newcurrentarray count]; i++) { a=(TransformedAcceleration *)[newcurrentarray objectAtIndex:i]; //NSLog(@"%d,%@",i,[a printAcceleration]); fprintf(fp,[[a printAcceleration] UTF8String]); //this is going wrong somewhow } fclose(fp); [array release]; [myFFT release]; //[array removeAllObjects]; [newcurrentarray release]; free(input); free(frequency);

• Painless way to install a new version of R?

  - by Shane

  Andrew Gelman recently lamented the lack of an easy upgrade process for R (probably more relevant on Windows that Linux). Does anyone have a good trick for doing the upgrade, from installing the software to copying all the settings/packages over? This suggestion was contained in the comments and is what I've been using recently. First you install the new version, then run this in the old verion: #--run in the old version of R setwd("C:/Temp/") packages <- installed.packages()[,"Package"] save(packages, file="Rpackages") Followed by this in the new version: #--run in the new version setwd("C:/Temp/") load("Rpackages") for (p in setdiff(packages, installed.packages()[,"Package"])) install.packages(p)

• Is a new thread in a Visual Studio test project aborted when the test ends?

  - by Michel

  Hi, i have to do some message exchange with a 3rd party (in a website). When the client posts a page, i start the message exchange. When that doesn't succeed for some reason, i report this to the client by rendering the page with a message. On the background, in a separate thread, i start a process to send abort messages to the 3rd party. I can't do this while the user is waiting for the page to come back, because it might take a few minutes. But in a test project, the test ends when the message to the 3rd party is sent, and after the new thread is started. But it seems that the new thread also ends, when the test is done. Is that normal behaviour? I do start the thread in a new class with a reference to 2 objects from the class which tries to send the message in the first place, may that be a problem?

• Javascript one-liners

  - by peoro

  Often I find some really cool javascript one liners that you can copy and paste into your browser address bar in order to get some fancy effects or even useful ones. This, for example, will let you edit anything on the page. javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 What is your favorite? EDIT: I know that technically all these snippets are just javascript scripts that gets evaluated by the browser as if they were defined in the page. I also know that many browsers have got extensions to let you run javascript code (also letting you store scripts somewhere, providing a good editor etc etc). However that's not so practical; I'm not a javascript developer, haven't got firebug installed, and I can't install it anywhere I go. My idea idea is that of collecting the best "mini-scripts" that whoever can just copy and paste in his browser without the need of installing extensions and stuff.

• How do I implement .net plugins without using AppDomains?

  - by Abtin Forouzandeh

  Problem statement: Implement a plug-in system that allows the associated assemblies to be overwritten (avoid file locking). In .Net, specific assemblies may not be unloaded, only entire AppDomains may be unloaded. I'm posting this because when I was trying to solve the problem, every solution made reference to using multiple AppDomains. Multiple AppDomains are very hard to implement correctly, even when architected at the start of a project. Also, AppDomains didn't work for me because I needed to transfer Type across domains as a setting for Speech Server worfklow's InvokeWorkflow activity. Unfortunately, sending a type across domains causes the assembly to be injected into the local AppDomain. Also, this is relevant to IIS. IIS has a Shadow Copy setting that allows an executing assembly to be overwritten while its loaded into memory. The problem is that (at least under XP, didnt test on production 2003 servers) when you programmatically load an assembly, the shadow copy doesnt work (because you are loading the DLL, not IIS).

• Network Services disabled (not starting) on Windows XP

  - by Rickesh John

  I am currently running Windows XP Service Pack 3 on my system. But today, when I failed to connect to the internet, via a LAN cable, I realized that almost all of the vital network services had stopped functioning. Any attempts to start it through services.msc gives me the following message: Could not start the DNS Client Service on Local Computer Error 1068: The dependency service group failed to start All my software or services that are related to networking have stopped functioning, for example, Windows Firewall is turned off permanently, so is my Avast Anti-Virus' service of Real Time Shields and Web Shield. When I insert the LAN wire into my laptop, it registers itself, but this is what I get when I do a ping localhost C:>ping localhost Unable to contact IP driver, error code 2 Moveover, with ipconfig I get this : Windows IP Configuration An internal error occurred: The request is not supported. Please contact Microsoft Product Support Services for further help. Additional Information: Unable to query host name On some further poking around, I saw that none of the "NETWORK SERVICE" process in task manager, except svchost.exe were running. Also, when I first opened the task manager, I saw some 20 processes running with username column empty for most of them. With some search in Google, I found out that these services were important, DHCP DNS Net logon Network connection Network location Awareness TCP/IP Net BIOS Helper none of them, except Network Connections are working, they do not start. The event viewer of my system shows a bunch of 7000 and 7001 event errors. I have tried re installing the network driver, booting in safe mode with networking and tried to enable those services mentioned above. I had disabled System Restore some time back, so I have no restore points for my system. I tried a lot of things from Google searches but none of them worked. Also, with such a long list of issue, I am a little confused as to what should I search on the internet. :( One more thing I would like to mention, previous morning, my anti-virus Avast detected a RootKit buried deep in my system folders. It was removed, but maybe this was a problem caused by the root kit. I did run a boot-time scan but no viruses were found. Please please please advice. Is formatting and re-installation of Windows my only option?

• getResourceAsStream returns HttpInputStream not of the entire file

  - by khue

  Hi, I am having a web application with an applet which will copy a file packed witht the applet to the client machine. When I deploy it to webserver and use: InputStream in = getClass().getResourceAsStream("filename") ; The in.available() always return a size of 8192 bytes for every file I tried, which means the file is corrupted when it is copied to the client computer. The InputStream is of type HttpInputStream (sun.net.protocol.http.HttpUrlConnection$httpInputStream). But while I test applet in applet viewer, the files are copied fine, with the InputStream returned is of type BufferedInputStream, which has the file's byte sizes. I guess that when getResourceStream in file system the BufferedInputStream will be used and when at http protocol, HttpInputStream will be used. How will I copy the file completely, is there a size limited for HttpInputStream? Thanks a lot.

• Best way to daemonize Java application on Linux

  - by SyBer

  Hi. While I found this question being answered here on SW several times, I didn't find a concluding answer what is the best approach. I'm not looking to use any external wrapper, as I found them launching the java process under a nice level lower then themselves which potentially lowers the performance, so it seems only the shell methods are left. I so far found 3 different shell methods: start-stop-daemon RedHat daemon init.d function nohup on start / disown after start What you people are using, and can recommend as the most reliable method? Thanks.

• How to create a win32 application without window in background with C?

  - by user563413

  The application do not need any window or console. It can be a console application if the console window can be removed or can be put into background. The application will do some simple tasks(such as cleaning rubbish files) and exit. I hope that the application should not be a windows service if possible. I hope that the application can be started with double-click in explorer window and run silently. When the application is running, I hope that the mouse cursor should not be changed to hourglass shape. That is to say, do not disturb the user when the application is running. Just run and exit silently. DO NOT NEED to run it when windows starts or user logins. I hope this can be done in C if possible. What should I do? Thanks!

• How can I set up a database (SQL?) for literary annotations?

  - by Jon

  I'm a literature student and I'd like to be able to annotate literary texts (originally stored in HTML or as text files) on a word-by-word or line-by-line basis. I hear databases like mySQL or SQLite would be good ways to do this sort of thing, but I don't really know where to start. I'm comfortable with the linux command-line, and have done some HTML/CSS work in the past, so I feel unintimidated by databases and things...I just don't know what to start doing.

• Launch x64 Windows application in C# while the project is set to x86

  - by daydr3am3r

  Hi all I'm trying to launch the osk.exe and I keep getting "Could not start osk" message. The problem is that my project is set to x86 (i'm using a ms access database). If I switch to x64 or Any CPU everything works fine but the database will no longer work. I tried this using System.Diagnostics; private void btnOSK_Click(object sender, EventArgs e) { Process.Start("osk.exe"); Process.Start(@"C:\windows\system32\osk.exe"); } I also tried to run SysWOWW\osk but this also didn't work. Besides my application should run on both x86 and x64 machines. Is there any way to bypass this? It's really frustrating.
