  • Convert data retrieved from MySQL database into JSON object using Python/Django

    - by rohanbk
    I have a MySQL database called People which contains the following schema <id,name,foodchoice1,foodchoice2>. The database contains a list of people and the two choices of food they wish to have at a party (for example). I want to create some kind of Python web-service that will output a JSON object. An example of output should be like: { "guestlist": [ {"id":1,"name":"Bob","choice1":"chicken","choice2":"pasta"},{"id":2,"name":"Alice","choice1":"pasta","choice2":"chicken"} ], "partyname": "My awesome party", "day": "1", "month": "June", "2010": "null" } Basically every guest is stored into a dictionary 'guestlist' along with their choices of food. At the end of the JSON object is just some additional information that only needs to be mentioned once. The question that I have is regarding the method that I need to utilize to grab the data from my database, and create the JSON object. Do I need to use a standard Model/View structure of Django or can I get away with something that is much simpler since what I need to do is really simple?

  • Deployment Setup (.Net) - Search target machine -> Registry search (64 bit)

    - by Joonas Kirsebom
    I have a windows installer project which installs some software (winform, service, mce addin). During the installation I need to search the machine for a registry key. This is done with with the "Launch Condition" - "Add Registry Search" (Deployment Project). I have filled out all the properties right, and checked against the regestry that the value actually can be found. The problem is that the "Registry Search" searches in the x86 part of the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\...) although my system is a x64 and the deployment setup is also set to x64. Does anyone know how to force the "Registry Search" to search the x64 registry? Or know about a workaround? The weird thing about this, is that Registry setting in the deployment setup is writing to the right registry (x64). My idea is that the "Registry Search" program is only developed to the x86 architecture, and therefore can't read the right registry. I found this article from microsoft, so it seams that they know about this problem. https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=110105&wa=wsignin1.0#details My system is: Windows 7 64bit Visual Studio 2008

  • Configuring Multiple ASP.NET MVC Sites To Use a Single Database For Authentication/Membership

    - by Maxim Z.
    Is it possible for two or more ASP.NET MVC sites to use a single SQL Server database for authentication and other things? Here's how I'm thinking of setting it up: I will combine the current database of each site into one single database, prefixing the tables with the name of the site they belong to. I currently have authentication tables generated by the asp.net_regsql.exe utility. How should I combine those tables? I'm guessing that the way to do it is to somehow set the "application_id" column in those tables... Thanks in advance.

  • Oracle Database character set issue with the audit tables on Debian

    - by Leonid Shirmanov
    I've got Oracle XE installed on Debian linux and the character set is configured to AL32UTF8. There are several client applications that connects to a database from Windows with the different locales - French etc, not English. That's ok with all the client data these applications put into database, nothing converted and text data in French represents correctly. But texts in audit tables looks like '??????' if contains any not-english character. I suppose this is because audit records go to database in the different locale and it's not dependent on the client's globalization/locale settings. How this globalization issue can be fixed? thanks!

  • Forms authentication for users and Windows for Database?

    - by scyonx
    On our production servers, the admins created a WebUser active directory account which is users for anonymous access to IIS and is also used to authenticate database access with our SQL Server instances using Integrated Security=SSPI in the connection string and identity impersonate="true" in the web.config. I've often come across situations where I would like to or even need to use forms authentication. However, I using forms authentication, Integrated Security seems to use the logged in user's credentials to authenticate against the database. In these cases I have changed the connection string to use the credentials of a SQL Server users instead. I would prefer to not have a hard coded username and password in the connection string or rather worse in code. Is it possible to use forms authentication just for user authentication for users and windows authentication with the IIS user for database access? What would be the best practice in such a situation?

  • Import received e-mails from Outlook to MSSQL database

    - by _simon_
    How can I automatically import some data from received e-mail from Outlook to MSSQL database? So, when I receive an e-mail (from a preset sender), Outlook should be able to run an external application with the subject and body as parameter. This application will then parse the body of the e-mail and send it to database. Is it possible to set this in 'Rules and alerts' in Outlook (I don't think so)? Or is it possible to do it with macros (an example would be nice). Or else...? I am using Microsoft Outlook 2007 (no Exchange Server), let's say, that incoming mail is from @gmail domain, the externam application would probably be a C# console application, database is SQL SERVER 2005.

  • Time Machine for Windows?

    - by Blub
    Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

  • Entity Framework with File-Based Database

    - by Dave Swersky
    I am in the process of developing a desktop application that needs a database. The application is currently targeted to SQL Express 2005 and works wonderfully. However, I'm not crazy about having this dependency on SQL Express and would prefer to use a small file-based database. My problem is that I am using Entity Framework. I have tried both SQL Compact and SQLite, and they both have bizarre problems with EF v1. I get errors creating the Model, invalid models when it does get created... it's a nightmare. I'm about ready to give up and write a data layer and repository in the good-old-school Connection/Command pattern. Not my favorite plan... Is there a lightweight, file-based database out there that plays well with EF? OR Is there a better ORM tool that I should use instead of EF with my lightweight DB?

  • Problems with ASP.NET, machine-level web.config, and the location element

    - by Daniel Schaffer
    I've got a server running Windows Web Server 2008 R2. The machine-level web.config has the following entries: <location path="Preview"> <appSettings> <add key="Environment" value="Preview" /> </appSettings> </location> <location path="Staging"> <appSettings> <add key="Environment" value="Staging" /> </appSettings> </location> <location path="Production"> <appSettings> <add key="Environment" value="Production" /> </appSettings> </location> I have a website that I'd set up in the direction D:\Sites\Preview\, so the full path would be D:\Sites\Preview\WebSite1. If I put a simple aspx file that just outputs the value of ConfigurationManager.AppSettings["Environment"], it displays the value Preview. I'm not clear on exactly how that works, but it does. I'd set this up several weeks ago, and just now tried to duplicate this - I put a second site in the D:\Sites\Preview\ directory, expecting that it would automatically pick up the appropriate appSettings entries, but for some reason it hasn't - the same aspx page doesn't show anything. Additionally, when I go into the IIS manager and open the Configuration Editor, there are no settings in there, whereas there are settings listed for the first site. Any ideas as to what I could be missing? Is the location element intended to work like this, or did I just find some magical fluke with my first site?

  • Problem with connection to MS SQL Server database using SSMS

    - by Charles
    I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server& LinkId=20476 ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) The server principal "cmitchell" is not able to access the database "3pointdb" under the current security context.

  • Cross-database transactions from one SP

    - by Michael Bray
    I need to update multiple databases with a few simple SQL statement. The databases are configurared in SQL using 'Linked Servers', and the SQL versions are mixed (SQL 2008, SQL 2005, and SQL 2000). I intend to write a stored procedure in one of the databases, but I would like to do so using a transaction to make sure that each database gets updated consistently. Which of the following is the most accurate: Will a single BEGIN/COMMIT TRANSACTION work to guarantee that all statements across all databases are successful? Will I need multiple BEGIN TRANSACTIONS for each individual set of commands on a database? Are transactions even supported when updating remote databases? I would need to execute a remote SP with embedded transaction support. Note that I don't care about any kind of cross-database referential integrity; I'm just trying to update multiple databases at the same time from a single stored procedure if possible. Any other suggestions are welcome as well. Thanks!

  • sqlcipher command line not working

    - by Min Lin
    I have a encrypted sqlite db and its key. (Which is generated by an android program). However, when I open the db in command line I can not read the db. The command line tool is installed by: brew install sqlcipher I open the database by: sqlcipher EnDB.db >pragma key="6b74fcd"; >select * from bizinfo; It keeps telling me "Error: file is encrypted or is not a database" However, if I open the database file with gui app sqlite database browser (which is a windows program and I run it in wine). It pops up a window for me to enter the key, with 6b74fcd as the key it successfully read the database. As I want to automatically process the db in the future, I can not depend on the GUI. Do you know why the command line is not working?

  • SQL Server 2008 automated database drop, create and fill

    - by lox
    For the database in my project I have a drop/create script for the database, a script for creating tables and SPs and an Access 2003 .mdb file with some exported values. To set up the database from scratch I can use my SQL management studio to first run one script, then the other and lastly manually run the sort of tedious import task. But I would like to do this as automated as possible. Hopefully something like putting the three files in a folder along with a fourth script to execute. Looking something like: run script "dropcreate.sql" run script "createtables.sql" import "values.mdb" How is this done? I hope to avoid using SSIS and the like. The tricky this is of course the import of data, where I can't seem to find a simple way. It is also important that the files a left as they are and not embedded into anything.

  • Sql Server 2008 Cross-database table linking (relationships)

    - by Alex
    Hi guys, I have a bit of an issue, and to be honest I don't think there's an answer, but I'll give it a try anyway. So I have two databases [A]-Company and [B]-Product. Both databases have a Country table which is then linked to other tables in each individual database. The problem is that the data between the two Country tables is a complete duplicate. So, I essentially have to duplicate some of the relationships in each database, and maintenance on top of that is just difficult... So, I'm curious is there a way to create a cross-database relationship between tables so I can have only one set of Country+Helper tables that govern both databases? Thanks in advance!

  • How to deploy ClickOnce .Net 3.5 application on 3.0 machine

    - by Buthrakaur
    I have .Net 3.5 SP1 WPF application which I'm successfully deploying to client computers using ClickOnce. Now I got new requirement - one of our clients need to run the application on machines equipped just with .Net 3.0 and it's entirely impossible to upgrade or install anything on the machines. I already tried to run the 3.5 application with some of the 3.5FW DLLs copied to the application directory and it worked without any problems. The only problem at the moment is ClickOnce. I already made it to include the 3.5FW System.*.dll files in list of application files, but it always aborts installation on 3.0 machine with this error message: Unable to install or run the application. The application requires that assembly System.Core Version 3.5.0.0 be installed in the Global Assembly Cache (GAC) first. Please contact your system administrator. I already tried to tweak prerequisites on Publish tab of my project, but no combination solved the issue. What part of ClickOnce is responsible for checking prerequisites? I already tried to deploy using mageui.exe, but the 3.5FW error is still present. What should I do to fore ClickOnce to stop checking any prerequisites at all? The project is created using VS2010.

  • Recovering transaction log from corrupt SQL database

    - by Don Kirkham
    We have a database that is backed up weekly in simple mode. Yesterday, we had a crc error corrupt the mdf file and we were unable to save it. I restored the backup from last week, but now we have a gap from the time of the backup to the time of the restore. Since I have the ldf file from that database, is there any way to "replay" that transaction log to fill in the gap? I have tried reattaching the ldf file to the recovered mdf file, but SQL will not allow me to do that. (It just creates a new ldf file with a different name when I reattach the database.) Any ideas would help. This is a lot of data to lose and although it is not critical data, I'd like to get it back (as well as learn as well as learn how to do it.)

  • How to determine Jet database Engine Type programmatically

    - by MZB
    I have a program which needs to upgrade any Access (Jet) database it opens to JET Version4.x if it isn't already that version. (This enables use of SQL-92 syntax features) Upgrading is (relatively) easy. A call to the JRO.JetEngine object's CompactDatabase method (as described here) should do the trick, but before I do this I need to determine whether an upgrade is required. How do I determine the Jet OLEDB:Engine Type of an existing database? Can this be determined from an open OleDBConnection? Note: I'm talking about database versions, not Jet library versions. C# or .Net solution greatly appreciated.

  • Resizing Images with ASP.NET and saving to Database

    - by Ryan
    I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database? Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes. Thanks!

  • Open an Access database and run one of its Macros from Excel

    - by sqlnoob
    From Excel, I need to open an Access database and run one of the database's macros. I'm using Excel and Access 2007. Here is my code in Excel: Sub accessMacro() Dim appAccess As New Access.Application Set appAccess = Access.Application appAccess.OpenCurrentDatabase "C:\blah.mdb" appAccess.Visible = True appAccess.DoCmd.RunMacro "RunQueries.RunQueries" appAccess.CloseCurrentDatabase End Sub In the Access Database, there is a procedure named RunQueries in a module named RunQueries. Each time I run this, I get the following error: Runtime error '2485': Microsoft Access Office can't find the object 'RunQueries.' I have also tried: appAccess.DoCmd.RunMacro "RunQueries" and I get the same errors message. Any idea how to do this? By the way, I could go into a long explanation about why I need to do this, but let me just say that I've already argued against it, and I have to do it this way (meaning, I have to use Excel as a frontend to open several Access dbs and run their macros).

  • Save in Sessions to reduce database load

    - by Kovu
    at the moment I try to reduce the load on my database extremly, so I had a look in my website and think about - what database calls can I try to avoid. So is there a rule for that? Sould I save every information in a Session that is nearly never changed? e.g.: The User-Table is a 35-coloumn-table which I need so often in so different ways, that in the moment I got this user-object at nearly every PageLoad AND in the master-site-page-load (Settings, display the username for a welcome message, colors etc etc.). So is that good to avoid the database query here, save the User-Object in a Session and call it from the session - and of course destroy the session whereever the User-Object get changed (e.g. User change his settings)?

  • CLR Function not working in restored database

    - by Ben Thul
    So I've restore a database with CLR assemblies in it from one physical server to another. One of the functions in the CLR assembly essentially does an uncompress of some compressed data. When I run this function against data in the restored database it returns the compressed data (rather than the uncompressed data). No error is thrown in SSMS or in the SQL server error logs. At the suggestion of others, I've checked differences in the database ownership (both owned by sa), trustworthiness (both set to not trustworthy). I also checked differences in the .NET framework installs on both machines but found only that the target machine had a 1.1 version installed that the source didn't. I don't know what else to try. Any suggestions would be most appreciated. Thanks in advance. Thanks in advance, Ben

  • Android insert into sqlite database

    - by Josh
    I know there is probably a simple thing I'm missing, but I've been beating my head against the wall for the past hour or two. I have a database for the Android application I'm currently working on (Android v1.6) and I just want to insert a single record into a database table. My code looks like the following: //Save information to my table sql = "INSERT INTO table1 (field1, field2, field3) " + "VALUES (" + field_one + ", " + field_two + ")"; Log.v("Test Saving", sql); myDataBase.rawQuery(sql, null); the myDataBase variable is a SQLiteDatabase object that can select data fine from another table in the schema. The saving appears to work fine (no errors in LogCat) but when I copy the database from the device and open it in sqlite browser the new record isn't there. I also tried manually running the query in sqlite browser and that works fine. The table schema for table1 is _id, field1, field2, field3. Any help would be greatly appreciated. Thanks!

  • JFLAP Turing Machine shortcut problem

    - by Robert Lamb
    In JFLAP (http://jflap.org), there are some shortcuts for Turing machine transitions. One of these shortcuts allows you to transition as long as the current tape symbol isn't the indicated symbol. For example, the transition !g,x;R basically says "Take this transition if the current tape symbol is not g". So far, so good. But the transition I want is !?,~;R which basically says "Move right as long as the current symbol is not the end-of-string (empty cell) symbol". The problem is I cannot figure out how to type in "!?". The JFLAP online documentation (http://www.jflap.org/tutorial/turing/one/index.html#syntax) has this to say: The first shortcut is that there exists the option of using the “!” character to convey the meaning of “any character but this character.” For example, concerning the transition (!a; x, R), if the head encounters any character but an “a”, it will replace the character with an “x” and move right. To write the expression “!?”, just type a “1” in when inputting a command. My question is...how do I actually do what that last sentence is trying to explain to me? Thanks for your help! Robert
