• Why does GetSqlDecimal throw when GetDecimal doesn't?

  - by I. J. Kennedy

  I have a database table that has a column of type money, allowing nulls. Using a SqlDataReader named reader, I can do decimal d = reader.GetDecimal(1); which works, unless of course we're reading a null. If I try using SqlDecimal instead--and I thought the whole point of the SqlTypes was to deal with nulls--then I get an invalid cast, whether or not the value is null. SqlDecimal s = reader.GetSqlDecimal(1); // throws an invalid cast exception What am I doing wrong? Do I really have to write a conditional statement to shepherd the value from the database to a SqlDecimal variable?

• SugarCRM - how to make users see only child users?

  - by John

  Hello, I want to change the behaviour of Sugar CRM community version. Here's what sugar currently does: 1) Admin logs into Sugar. 2) Admin clicks on Admin tab. 3) Admin creates a new user named George with admin access 4) Under user information section, Admin makes George report to Admin (in the database, it will show users.report_to_id is the admin's user_id) 5) Admin saves and logs out 6) George logs in with his password 7) George goes to admin tab. 8) George goes to list users page and sees all users, including Admin, the person he is supposed to report to. I want to change step 8 such that George is not allowed to see the user he reports to. Additionally, he is not allowed to see his grand parent user, great grand parent user, great great grand parent user etc... George should only be able to see users that he creates. How can I achieve this? Is this even possible?

• How to aggregate bindings in Silverlight UserControl

  - by Peter Wone

  Imagine a UserControl containing some sort of ItemsControl. The UserControl as a whole has a DataContext, but you also need to expose the ItemsSource of the ItemsControl. I have tried all manner of arrangements, and eventually passed a DomainDataSource as a UserControl dependency property named DDS, and bound the ItemsControl like this: ItemsSource="{Binding DDS.Data, ElementName=userControl}" It works, but this is mucky, and with Silverlight mucky is nearly always a sign of incorrect approach. Your advice is sought. It looks like multi-bindings might be the answer to this.

• Extending Code Igniter Model functions to external PHP Scripts

  - by Fábio Antunes

  Hello everybody. I'm doing a small web app, which uses CKeditor for user input, and CKfinder for file management (images/flash).

This is were a Custom PHP Code checks if the user as authorization to access CKFinder or not. Well for my app I'm using Code Igniter, and of course I've created a model were i handle everything about User Permissions, Loggin, Session Cookies, etc. And i also have a function witch its propose is just to check if the user is Logged in. So I would like to know if someone knows a way that i can call the function isLoggedIn() inside the model security from inside the function CheckAuthentication() in CKFinder config file.

• Export ASPNETDB data to another Database.

  - by raziiq

  Hi there. I am developing in Visual Web developer 2008. I have SQLEXPRESS 2005 and SQL Management Studio 2008 installed on my PC. I purchased a Database MS SQL 2008 on DiscountASP.net. Since the host provides only 1 database and my project has 2 database. One is the ASPNETDB that contains the roles and user etc (created using the Website Configuration Wizard) and the other is my database containing data to my website and is named MainDB. As Host allows only 1 database so i exported my ASPNETDB's tables and stored procedures to my MainDB using aspnet_regsql.exe, but the problem is that stored procedures and tables are exported to my MainDB but data is not exported, i mean there are no users in the tables. My Question is how to export everything of ASPNETDB including stored procedures, tables and data to my MainDB??

• Ant trouble with environment variables on Ubuntu

  - by Inaimathi

  Having some trouble with with ant reading environment variables in Ubuntu 9.10. Specifically, the build tasks my company uses has a token like ${env.CATALINA_HOME] in the main build.xml. I set CATALINA_HOME to the correct value in /etc/environment, ~/.pam_environment and (just to be safe) my .bashrc. I can see the correct value when I run printenv from bash, or when I eval (getenv "CATALINA_HOME") in emacs. Ant refuses to build to the correct directory though; instead I get a folder named ${env.CATALINA_HOME} in the same directory as my build.xml. Any idea what's happening there, and/or how to fix it?

• key value coding-compliant for NSObject class?

  - by 4thSpace

  I've created a singleton class that loads a plist. I keep getting this error when I try to set a value: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key test.' I have one key in the plist file. The key is named "test" and has no value associated with it. I set the value like this: [[PlistManager sharedManager].plist setValue:@"the title value" forKey:@"test"]; I look at the set plist dictionary and see this from within PlistManager: po self.plistDictionary { test = ""; } I get the error just as I'm leaving PlistManager in the debugger. PlistManager is of type NSObject. So no xibs. Any ideas on what I need to do?

• SQL Server CONTAINS with digits gives no results

  - by dale

  Hi, I have a database table which is full-text indexed and i use the CONTAINS-function to perform a search-query on it. When I do: SELECT * FROM Plants WHERE CONTAINS(Plants.Description, '"Plant*" AND "one*"'); I get back all correct results matching a description with the words "Plant" and "one". Some plant are named like "Plant 1", "Plant 2" etc. and this is the problem. When i do this, i get no results: SELECT * FROM Plants WHERE CONTAINS(Plants.Description, '"Plant*" AND "1*"'); Anyone know why?

• web.config, configSource, and "The 'xxx' element is not declared" warning.

  - by UpTheCreek

  I have broken down the horribly unwieldy web.config file into individual files for some of the sections (e.g. connectionStrings, authentication, pages etc.) using the configSource attribute. This is working file, but the individual xml files that hold the section 'snippets' cause warnings in VS. For example, a file named roleManager.config is used for the role manager section, and looks like this: <roleManager enabled="false"> </rolemanager> However I get a blue squiggle under the roleManager element in VS, and the following warning: The 'roleManager' element is not declared I guess this is something to do with valid xml and schemas etc. Is there an easy way to fix this? Something I can add to the individual files? Thanks P.S. I have heard that it is bad practice to break the web.config file out like this. But don't really understand why - can anyone illuminate me?

• Sparse checkout in Git 1.7.0?

  - by davr

  With the new sparse checkout feature in Git 1.7.0, is it possible to just get the contents of a subdirectory like how you can in SVN? I found this example, but it preserves the full directory structure. Imagine that I just wanted the contents of the 'perl' directory, without an actual directory named 'perl'. -- EDIT -- Example: My git repository contains the following paths repo/.git/ repo/perl/ repo/perl/script1.pl repo/perl/script2.pl repo/images/ repo/images/image1.jpg repo/images/image2.jpg repo/doc/ repo/doc/readme.txt repo/doc/help.txt What I want is to be able to produce from the above repository this layout: repo/.git/ repo/script1.pl repo/script2.pl However with the current sparse checkout feature, it seems like it is only possible to get repo/.git/ repo/perl/script1.pl repo/perl/script2.pl which is NOT what I want. Thanks.

• Suggestion for chkstk.asm stackoverfolw exception in C++ with Visual Studio 2010

  - by Gulshan

  I am working with an implementation of merge sort. I am doing C++ Visual Studio 2010. But when I took a array of 300000 integers for timing, it is showing an unhandled stackoverflow exception and taking me to a readonly file named "chkstk.asm". I reduced the size to 200000 and it worked. Again the same code worked with C-free 4 editor (mingw 2.95) without any problem while the size was 400000. Do you have any suggestion to get the code working in Visual Studio? May be the recursion in the mergesort is causing the problem.

• Problem creating ObjectContext from different project inside solution.

  - by Levelbit

  I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

• jQuery Javascript array 'contains' functionality?

  - by YourMomzThaBomb

  I'm trying to use the jQuery $.inArray function to iterate through an array and if there's an element whose text contains a particular keyword, remove that element. $.inArray is only returning the array index though if the element's text is equal to the keyword. For example given the following array named 'tokens': - tokens {...} Object [0] "Starbucks^25^http://somelink" String [1] "McDonalds^34^" String [2] "BurgerKing^31^https://www.somewhere.com" String And a call to removeElement(tokens, 'McDonalds'); would return the following array: - tokens {...} Object [0] "Starbucks^25^http://somelink" String [1] "BurgerKing^31^https://www.somewhere.com" String I'm guessing this may be possible using the jQuery $.grep or $.each function, or maybe regex. However, I'm not familiar enough with jQuery to accomplish this. Any help would be appreciated!

• Php character coding

  - by out_sider

  I have a file named index.php which using a mysql server gets a simple username. The mysql server is running on centOS and I have two different systems running apache serving as web servers. One is my own windows pc using a "wamp" solution which uses the mysql server refereed before and the other is the centOS server itself. I use this so I can develop in my laptop and run the final on the centOS box. The problem is this: Accessing centOS box I get (on hxxp://centos): out_sider 1lu?s 2oi Using wamp on windows I get (on hxxp://localhost): out_sider 1luís 2oi The mysql database is configured correctly seeing that both use the same and I used svn repository to move files from windows to centOS so the file is the same. Does anyone have any suggestions? Thanks in advnce

• Suppressing NSLog statements for release?

  - by fuzzygoat

  I wonder if someone could help me setup a number of NSLog statements so they print to console when executing in "Debug Mode" but don't print in "Release Mode". I understand I need to add something like DEBUG = 1 to the debug config in Xcode but I can't find where. Also how do I utilise this in my code? NSLog(@"Print Always"); if(DEBUG) NSLog(@"Print only in debug"); Is there a simple way of doing this? EDIT: I tried following this but when I entered either: OTHER_CFLAGS or GCC_PREPROCESSOR_DEFINITIONS Xcode informed me that "theres already another key named .... " gary

• How can I bind a winforms Opacity to a TrackBar (slider)

  - by Allen

  I've got a winform with a BindingSource that has an int property named Opacity in its DataSource. I also have a TrackBar on the winform that I want to use to control the Opacity of the winform. I've bound the Value property on the TrackBar to the Opacity and that functions just fine, sliding the TrackBar will change the variable from TrackBar.Minimum (0) to TrackBar.Maximum (1). I've also bound the Opacity property of the winform to this value, however, since the TrackBar's values only go from Minimum to Maximum in +/-1 rather than +/- .1 or so (like Opacity does), it doesn't properly fade the winform. Instead, 0 will turn it opaque and 1 will turn it fully visible. I need a way to work within the architecture described above, but get the TrackBar to change its value from 0 to 1 in defined increments smaller than 1.

• OpenCV 2.0 and Python

  - by Jive Dadson

  I cannot get the example Python programs to run. When executing the Python command "from opencv import cv" I get the message "ImportError: No module named _cv". There is a stale _cv.pyd in the site-packages directory, but no _cv.py anywhere. See step 5 below. MS Windows XP, VC++ 2008, Python 2.6, OpenCV 2.0 Here's what I have done. Downloaded and ran the MS Windows installer for OpenCV2.0. Downloaded and installed CMake Downloaded and installed SWIG Ran CMake. After unchecking "ENABLE_OPENMP" in the CMake GUI, I was able to build OpenCV using INSTALL.vcproj and BUILD_ALL.vcproj. I do not know what the difference is, so I built everything under both of those project files. The C example programs run fine. Copied contents of OpenCV2.0/Python2.6/lib/site-packages to my installed Python2.6/lib/site-packages directory. I notice that it contains an old _cv.pyd and an old libcv.dll.a.

• ssms cannot connect to default sql server instance without specifying port number

  - by Oliver

  I have multiple SQL Server 2005 instances on a box. From SSMS on my desktop I can connect to that box's named instances with no problem. After some recent network configuration changes, when I want to connect to the default instance from SSMS on my desktop, I have to specify the port number. Before the network changes, I did not have to specify the port number of the default instance. If I remote to any other box (including the one in question), and use that box's SSMS to connect to that default instance, success. From my desktop, and only from my desktop, I have to specify the port number. Is it a SQL Server configuration that I've missed? Is it possible something in my PC's configuration is getting in the way? Where would I look, or what could I pass on to the network folks to help them resolve this? Any help is appreciated.

• Using Graphics2D to overlay text on a BufferedImage and return a BufferedImage

  - by Andrew Bolster

  I have checked similarly named questions, but they don't answer this use case. Basically, I was to overlay some text (text) at a given coordinate (x,y) I have the below function in a package; protected BufferedImage Process2(BufferedImage image){ Graphics2D gO = image.createGraphics(); gO.setColor(Color.red); gO.setFont(new Font( "SansSerif", Font.BOLD, 12 )); gO.drawString(this.text, this.x, this.y); System.err.println(this.text+this.x+this.y); return image; } I feel like im missing something patently obvious; every reference to Graphics2D I can find is dealing with either games or writing directly to a file but I just want a BufferedImage returned. with the overlay 'rendered' In the current code, the image appears out the end unchanged. Thanks!
