  • nHibernate one-to-many inserts but doesnt update

    - by user210713
    Instead of getting into code, I have a simple question. Default behavior for a simple one-to-many is that it inserts the child record then updates the foreign key column with the parent key. Has anyone ever had a one-to-many where the child object gets inserted but not updated resulting in a row in my table with a null in the foreign key column? I want the default behaviour for a standard one-to-many. I don't want to have to add the parent as a property to the child. Thanks.

  • CakePHP 'Cake is NOT able to connect to the database'

    - by kand
    I've looked at this post about a similar issue: CakePHP: Can't access MySQL database and I've tried everything they mentioned in there including: Changing my database.php so that the 'port' attribute for both $default and $test are the location of my mysqld.sock file Changing the 'port' attribute to the actual integer that represents the port in my my.cnf mysql config Changing the mysql socket locations in php.ini to the location of my mysqld.sock file I'm using ubuntu 11.04, apache 2.2.17, mysql 5.1.54, and CakePHP 1.3.10. My install of mysql and apache don't seem to match any conventions, as in, all the config files are there, they are all just in really weird places--I'm not sure why that is, but I've tried reinstalling both programs multiple times with the same results... At any rate, I can log into mysql from the terminal and use it normally, and apache is working because I can see the CakePHP default homepage. I just can't get it to change the message 'Cake is NOT able to connect to the database'. SOLVED: Figured it out, had to change php.ini so that extension_dir pointed to the correct directory and had to add a line extension=mysql.so.

  • Finding the Formula for a Curve

    - by Mystagogue
    Is there a program that will take "response curve" values from me, and provide a formula that approximates the response curve? It would be cool if such a program would take a numeric "percent correct" (perhaps with a standard deviation) so that it returns simplified formulas when laxity is permissable, and more precise (viz. complex) formulas when the curve needs to be approximated closely. My interest is to play with the response curve values and "laxity" factor, until such a tool spits out a curve-fit formula simple enough that I know it will be high performance during machine computations.

  • Optional read from STDIN in C

    - by Yuval A
    My application is basically a shell which expects an input of type cmd [x], where cmd is constant and x is optional. So cmd 1 is legal as well as cmd by itself - then I assume a default parameter for x. I am doing this: char cmd[64]; scanf("%s", cmd); int arg; scanf("%d", &arg); // but this should be optional How can I read the integer parameter, and set it to a default if none is currently available in the prompt? I do not want the prompt to wait for additional input if it was not given in the original command. I tried several versions using fgetc() and getchar() and comparing them to EOF but to no avail. Each version I tried ends up waiting on that optional integer parameter.

  • Ways to call Blocks within Magento: createBlock vs Layout xml file

    - by N. B.
    Context: I'm trying to include Adminhtml blocks in the frontend of the site to replace some of the user account blocks. The first thing I'm trying to do is simply display the block on the correct page. I can replace the entire page by setting the Body of the response inside the controller, but I'm having a hard time including the block in the layout xml file and then calling it within the template. Why would I be able to create an adminhtml/sales_order_grid from Mage_Sales_OrderController using createBlock: $this->getResponse()->setBody($this->getLayout()->createBlock('adminhtml/sales_order_grid')->toHtml()); But not from a frontend layout, using a declaration <block type="adminhtml/sales_order_grid" name="orders_widget"/> within app/design/frontend/default/default/layout/sales.xml The latter produces an error without a stack trace: Fatal error: Call to a member function toHtml() on a non-object in app/code/core/Mage/Core/Model/Layout.php on line 526 Thanks for any guidance!

  • Glew in VS 2010: unresolved external symbol __imp__glewInit

    - by NoviceCai
    I am learning OpenGL by following the redbook. When I come to around page 90, I need use glGenBuffers(); Then I need install "glew". By following the steps in www.cs.uiowa.edu/~cwyman/classes/common/howto/winGLUT.html I download glew.zip from glew.sourceforge.net/ and unpack the files. I put glew.h in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include and put glew32.lib in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib and put glew32.dll in C:\Windows\System32. After that, I build my project in VS 2010 and in Linker-input, I add dependencies glew32.lib. But when I build it, I have error unresolved external symbol _imp_glewInit I spend whole day to search solutions, but did not find one. Hope someone can help me with this.

  • Synclock a section of code while waiting for ShowDialog to return

    - by clawson
    I'm having trouble working out how to lock my application out of a section of code while it waits for a response from an external program. I've used Synclock on a section of code with the Me object in the expression. In this Synclock I call an overridden ShowDialog method of a dialog box, which has a timeout parameter, but does return the value from the underlying ShowDialog function call ,once the timer is setup. Works like this. SyncLock Me Dim frmDlgWithTimeout As New frmDlgWithTimeout ' dialog box with overridden ShowDialog ' Dim res As DialogResult = frmDlgWithTimeout.ShowDialog(10 * 1000) ' 10 sec timeout ' End SyncLock Now, external programs may raise events that bring my application to this Synclock but it doesn't prevent it from entering it, even though the ShowDialog function hasn't returned a value (and hence what I thought would keep the section of code locked). There is only one instance of the object that is used for lock in the program. Your help is greatly appreciated.

  • JAVA: storing input into array

    - by Jann
    I need to write a program where the program would generate random letter and i would need to store this random character into an array char[] arrayRandom = new char[10]; for (int i = 0; i < 8; i++) { randomNumLet = (generator.nextInt(20) + 1); System.out.print(arrayRandomLetter[randomNumLet] + " "); arrayRandomLetter[randomNumLet] = arrayRandom[i]; } is there anything wrong with my code? because when i run this and printed the array i get boxes for all the values in the array and there are some letter that this line of code cannot print System.out.print(arrayRandomLetter[randomNumLet] + " "); Thanks

  • Solve equation from string to result in C

    - by Alexandre Cassagne
    Hi, I would like to know if anyone has info or experience on how to do something which sounds simple but doesn't look like it when trying to program it. The idea is : give a string containing an equation, such as : "2*x = 10" for example (this is simple, but it could get very complex, such as sqrt(54)*35=x^2; and so on....) and the program would return x = 5 and possibly give a log of how he got there. Is this doable ? If so, does anyone have a lead ? For info there is this site (http://www.numberempire.com/equationsolver.php) which does the same thing in PHP, but isn't open source. Thanks for any help !

  • Determine which process (b)locks a file, programmatically (under Windows >= XP)

    - by fred-hh
    How to programmatically determine from a process P, which other process P' has a lock on a file, that prevents P from recreating that file ? I know there are tools to do that, but how do they achieve that ? (Context: a batch program that runs overnight fails because of a locked file. Running an admin tool the next day may be too late to get useful information. So it would be nice if the batch program itself was able to determine the culprit.) EDIT: Added complexity: the file resides on a DFS and P' might not run on the same machine as P (but maybe does). But a solution that works locally would be a good beginning.

  • Cannot do a ncurses overwrite(curscr, savewin) correctly because I ripoffline() before

    - by Costi
    I have a C/ncurses program that I'm debugging/maintaining. This program does ripoffline twice: first, to put a title bar and the second time to put a menu bar on the top of the page. I need to dropdown some menus so I save the screen before I drop down the menus. In the InitMenu function, I have the following code: savewin = newwin (0, 0, 0, 0); overwrite (curscr, savewin); wrefresh(savewin) The problem is that savewin is being copied WITH the menu and the ripped off lines, but it gets drawn on the screen BELOW the rippedoff lines. This duplicates the ripped off lines on the screen. Only realizing where the problem was took me a while. Now, I have no idea how to fix it. Ideally, I would like to copy curscr to savewin without the ripped off lines. Any ideas?

  • Shutting down a WPF application from App.xaml.cs

    - by Johannes Rössel
    I am currently writing a WPF application which does command-line argument handling in App.xaml.cs (which is necessary because the Startup event seems to be the recommended way of getting at those arguments). Based on the arguments I want to exit the program at that point already which, as far as I know, should be done in WPF with Application.Current.Shutdown() or in this case (as I am in the current application object) probably also just this.Shutdown(). The only problem is that this doesn't seem to work right. I've stepped through with the debugger and code after the Shutdown() line still gets executed which leads to errors afterwards in the method, since I expected the application not to live that long. Also the main window (declared in the StartupUri attribute in XAML) still gets loaded. I've checked the documentation of that method and found nothing in the remarks that tell me that I shouldn't use it during Application.Startup or Application at all. So, what is the right way to exit the program at that point, i. e. the Startup event handler in an Application object?

  • How to structure a multilingual website for search engines?

    - by Nirmal
    I have this website which decides on the display language by a GET parameter. http://www.mysite.com/index.php?page=home&locale=en which is rewritten as http://www.mysite.com/en/home When no language is specified, the system defaults to English (en). Now how do I tell the search engines that many versions of the website exist? When the search bot enters the site, it will trigger the default English Language and after finishing, will just leave the site without considering other languages. I can very well have a sitemap with links to the default pages of each language, so the bot can navigate from there. But how do I say the bot that the entry in the sitemap is the home page for that language? Like if someone searches for 'mi sitio', they should be presented with the result http://www.mysite.com/es/home and not some other internal page. Any light on this? Thanks.

  • Windows 7 running as server

    - by Artur
    I'm developing a program using Windows 7. There are WCF services (soap, rest) that are used by currently by Silverlight but very soon I'll start development of the mobile application that would make use of these services. On day to day basis I use Mac and Apache to host my website, but during the development of this program I would like to use IIS7 to put my services online. I have absolutely no problems to access all the services via localhost but as soon as I'm trying to connect through the internet I get "The connection has timed out". I'm sure that my router is configured right as it works perfectly fine when I'm on Mac OS, but it looks like Windows simply blocks incoming connections from outside; I cannot even connect from another computer on the same network. So is there a way of using Windows 7 as server with IIS7 or is it only possible with Windows Server? I know it might be like enabling/disabling one setting somewhere but I just cannot find it. Please help.

    I have been doing the Ruby in 100 minutes on the JumpStart labs website, and encountered a problem during part 5.

  • Output excel spreadsheets with or without Office PIA

    - by user144182
    I have a program that currently outputs Excel via SpreadsheetML files. I build these using streams. This is very space inefficient for Excel; the files can be 5 to 6 times as large as other Excel binary formats. I would like to output a binary excel format such as .xls or .xlsx, but I don't want to have the installation of the program depend on Office. Some users might have it installed, some might not. How can I handle this gracefully? Is it possible to not have an assembly as a dependency but based on the user enabling binary output still use the assembly?

  • .NET ORM and Security

    - by Sphynx
    We're going to use an ORM tool with a .NET desktop application. The tool allows creation of persistent classes. It generates all database tables automatically. In addition to other data, our system needs to store user credentials, and deliver access control. The question is, is there any possibility of access control by means of ORM, without creating the database authentication mechanisms manually? Is there any product on the market which allows this? We thought of limiting the access in the program itself, but users can easily access the database directly, and bypass the program limitations. Thanks.
