• sqlite - Foreign keys in VS2008 Designer

  - by rene marxis

  Hello I'm starting over to use strong typed datasets in VS 2008 with sqlite and running into a problem. I have some tables that have foreign keys allready defined in the database. I can see those in the Server-Explorer. Now i create a new strong typed Dataset with the designer and add only one table from that realtion to the dataset. Then i like to add the second one and i get an error message "Unexpected error ... Source: Microsoft.VSDesigner; ErrorCode:-1" No Additional Info. The error does not occure if i add both tables at the same time (say i drag them from the serverexplorer). Is there any way to add subsequent tables to an dataset that are in relation(s) to alreay added once? Many thanks _rene

• no ocijdbc10 in java.library.path

  - by B.Z.B

  Hey all, So I've been plagued by this issue, whenever I try to run my app in eclipse, I get this error. 2011-02-23 09:55:08,388 ERROR (com.xxxxx.services.factory.ServiceInvokerLocal:21) - java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.path I've tried following the steps I found here with no luck. I've tried this on a XP VM as well as windows 7 (although in win 7 I get a different error, below) java.lang.UnsatisfiedLinkError: no ocijdbc9 in java.library.path I've made sure my oracle client was ok (by running TOAD) and I also re-added the classes12.jar / ojdbc14.jars to my WEB-INF/lib folder taken directly from my %ORACLE_HOME% folder (also re-added them to the lib path). I've also tried just adding the ojdbc14.jar without the classes12.jar. Any suggestions appreciated. In the XP VM I have my PATH variable set to C:\Program Files\Java\jdk1.6.0_24\bin;C:\ORACLE\product\10.2.0.1\BIN. I'm using Tomcat server 5.0

• Sun webstack vs Installing PHP, MySQL, Apache individually

  - by Vincent

  Is it possible to install PHP, MySQL, Apache individually on Solaris instead of installing them through a webstack? What are the advantages and disadvantages? I seem to frequently get a CURL error on Solaris when dealing with HTTPS sites. (error:81072080:lib(129):func(114):reason(128). I have no clue why that error is occuring and thought it might solve it, if I upgrade to latest PHP,MySQL,Apache versions. At this point I am not even sure if it's a Solaris issue. Any advice? Thanks

• Problem with Wicket and SignInExample in IE8

  - by KJQ

  I have an interesting problem with Wicket. I'm basically duplicating the 'authentication' example from the v1.4.x in SVN. It works fine in FireFox and Chrome but not in IE8. When in IE8, after I click the submit button it returns with a 404 error but i can manually paste the "destination" url in and it goes there fine (as an authenticated user). Another scenario is, I try to login, it gives me a 404, I hit refresh (looking at the html source I see the page version incremented), relogin and it works fine. So to summarize: I login the first time in IE8 and it returns a 404 error, hit refresh and ogin again and it works fine. I login the first time in IE8 and it returns a 404 error, manually paste the destination url in the browser and it goes there fine as if im logged in. I've compared everything between IE8 and FireFox from the rendered source and the code is not doing anything special but I cannot figure out what the differences are? Thanks. KJQ

• How to add a sequence column to an existing table with records

  - by user1888543

  I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used, CREATE TABLE USERLOG AS SELECT C_IP, WEB_LINK FROM weblog_views; I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I need help with this part. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option, ALTER TABLE USERLOG ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT; But I get an error with this, Error report: SQL Error: ORA-01735: invalid ALTER TABLE option 01735. 00000 - "invalid ALTER TABLE option" So, I would really appreciate any help that I can get!

• What is the best way to mock a 3rd party object in ruby?

  - by spinlock

  I'm writing a test app using the twitter gem and I'd like to write an integration test but I can't figure out how to mock the objects in the Twitter namespace. Here's the function that I want to test: def build_twitter(omniauth) Twitter.configure do |config| config.consumer_key = TWITTER_KEY config.consumer_secret = TWITTER_SECRET config.oauth_token = omniauth['credentials']['token'] config.oauth_token_secret = omniauth['credentials']['secret'] end client = Twitter::Client.new user = client.current_user self.name = user.name end and here's the rspec test that I'm trying to write: feature 'testing oauth' do before(:each) do @twitter = double("Twitter") @twitter.stub!(:configure).and_return true @client = double("Twitter::Client") @client.stub!(:current_user).and_return(@user) @user = double("Twitter::User") @user.stub!(:name).and_return("Tester") end scenario 'twitter' do visit root_path login_with_oauth page.should have_content("Pages#home") end end But, I'm getting this error: 1) testing oauth twitter Failure/Error: login_with_oauth Twitter::Error::Unauthorized: GET https://api.twitter.com/1/account/verify_credentials.json: 401: Invalid / expired Token # ./app/models/user.rb:40:in `build_twitter' # ./app/models/user.rb:16:in `build_authentication' # ./app/controllers/authentications_controller.rb:47:in `create' # ./spec/support/integration_spec_helper.rb:3:in `login_with_oauth' # ./spec/integration/twit_test.rb:16:in `block (2 levels) in <top (required)>' The mocks above are using rspec but I'm open to trying mocha too.

• SSL totally stopped working in Windows

  - by Dims

  Apparently, on my notebook, I have suddenly lost any ability to use network connections, involving SSL and/or data encryption, provided my MS: 1) remote desktop connections: Because of an error in data encryption, this session will end 2) browse HTTPS sites: Can't browse HTTPS pages. TLS error 3) communicate over WiFi, while wired is ok Is there any possible one central reason for all of these problems in Windows? Third party applications, like Putty, works fine. Is it possible to reset/repair certificate store or something in Windows?

• Sql server management studio reporting "The semaphore timeout period has expired."

  - by nis-simonsen

  On our development sql server, executing any query containing more than approximately 700 characters stalls for about 10 seconds and then reports the following error: Msg 121, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) for example, this query select * from FooTable where id = ' (.. and then 700 spaces ..) ' fails fails with the timeout error while this one select * from FooTable where id = ' (.. and then 600 spaces ..) ' fails with the expected Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. - immediately. Indeed, throwing any query, including random garbage at our dev sql server exhibits this behaviour, while any other sql server I have available acts as expected, so I would think that the query never actually gets to parsing on the server. I'm at a loss here - any hints?

• How do I delete a worksheet from a Google speadsheet?

  - by Homer

  I know it sounds simple but I have 2 problems. On the first sheet I can delete the worksheet by clicking on the tab dropdown and clicking delete, but it reappears when I leave and come back. On the second sheet I can't do that at all because I get a js error so the page never loads. The error is related to http://spreadsheets.google.com/client/js/499703333-trix_waffle_core.js

• C# Bug or Brain Teaser? Cast working only with Coalesce (??) Operator

  - by Alex

  This is very strange, maybe someone can explain what's happening, or this is a bug (though I tend to think that this is probably just something intricate about C#). The following code throws the error "Cannot implicitly convert type 'uint?' to 'uint'.": public void Test(UInt32? p) { UInt32 x = p; } However, this code works without error: public void Test(UInt32? p) { UInt32 x = p ?? 1; } Huh? Why does this work? Why would the coalesce operator cause implicit conversion of UInt32? (nullable) to UInt32 (non-nullable), while the first error message says that there is no implicit conversion between those types?

• floating constants in C

  - by Daziplqa

  Hi floks, I have a question concerning floating constants in C. In Java, the default type of floating point constants in double, so the following will causes a compilation error in java: float f = 100.0; // we either need to uses type case operator or put f at the end of the number constant. This is because the default floating-point constants are of type double and casting from double to float without type cast operator is an error, so we need either add a type case operator or put f at the end of the number. So, Why in C this doesn't produce an error, Is it because the default floating-point constants are of type float, or because the compiler do an implicit down-cast conversion (that doesn't requires type case operator in C)????

• Outlook 2010 says "File is in use by another application or user" while closing

  - by A_Pointar

  Outlook opens, gets new emails and everything but when I close it, it gives me the following error and then opens up a Save a File window after I cancel this error message. There's no other computer that may be using Outlook under this User Name because I just set-up a brand new User Name. However, Colligo Briefcase is attached to the Outlook and not sure if this is triggering and if so how I address the issue!? Thanks a lot!

• What to log when an exception occurs?

  - by Rune

  public void EatDinner(string appetizer, string mainCourse, string dessert) { try { // Code } catch (Exception ex) { Logger.Log("Error in EatDinner", ex); return; } } When an exception occurs in a specific method, what should I be logging? I see a lot of the above in the code I work with. In these cases, I always have to talk to the person who experienced the error to find out what they were doing, step through the code, and try to reproduce the error. Is there any best practices or ways I can minimize all this extra work? Should I log the parameters in each method like this? Logger.Log("Params: " + appetizer + "," + mainCourse + "," + dessert, ex); Is there a better way to log the current environment? If I do it this way, will I need to write out all this stuff for each method I have in my application? Are there any best practices concerning scenarios like this?

• create a folder and files in c:\program files\myApp\data in windows 7

  - by ile

  I have an old c++ application that needs to be modified to work with windows 7. Problem is in creating a new folder and saving a file in that folder. This folder should be created in c:\program files\myApp\data\newFolder. This is function I use to create new folder and get errors: if(!CreateDirectory(pathSamples,NULL)) //Throw Error { DWORD errorcode = GetLastError(); LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, errorcode, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL ); MessageBox(NULL, (LPCTSTR)lpMsgBuf, TEXT("Error"), MB_OK); } In XP this works, but in Windows 7 it doesn't. If I run application as administrator than the folder is created, otherwise "Access is denied" error is thrown. My question is following: Is there an option to make changes to the code so that the folder can be created in "program files" nad that files can be saved in this folder? PS I saw this thread already but it doesn't answer my question. Thanks, Ilija

• Why is 'volatile' parasitic in C++?

  - by Steve

  Consider the following code: int main() { int i; volatile int* p = &i; int *v = p; return 0; } This gives an error in g++: $ g++ -o volatile volatile.cpp volatile.cpp: In function ‘int main()’: volatile.cpp:6: error: invalid conversion from ‘volatile int*’ to ‘int*’ My intention was that I want to make p volatile. However, once I've read the value of p, I don't care if accessing v is volatile. Why is it required that v be declared volatile? This is hypothetical code of course. In a real situation you could imagine that p points to a memory location, but is modified externally and I want v to point to the location that p pointed to at the time of v = p, even if later p is externally modified. Therefore p is volatile, but v is not. By the way I am interested in the behaviour both when this is considered C and C++, but in C this only generates a warning, not an error.

• MinGW screw up with COLORREF and RGB

  - by kjoppy

  I am trying to build a 3rd party open source project using MinGW. One of the dependencies is wxWidgets. When I try to make the project from MSYS I get a compiler error from /MinGW/msys/1.0/local/include/wx-2.8/wx/msw/private.h In function 'COLORREF wxColourToRGB(const wxColour&)': error: cannot convert 'RGB' to 'COLORREF {aka long unsigned in}' in return This is somewhat odd given that, according to Microsoft the RGB macro returns a COLORREF. In fact, looking in H:\MinGW\include I find wingdi.h with the following code #define RGB(r,g,b) ((COLORREF)((BYTE)(r)|((BYTE)(g) << 8)|((BYTE)(b) << 16))) What sort of thing would cause this error? Is there some way I can check to see if COLORREF and RGB are being included from wingdi.h and not somewhere else? Is that even worth checking? Specifications GCC version 4.7.2 wxWidgets version 2.8.12 (I'm new to C++ and MinGW specifically but generally computer and programming literate)

• How can I impersonate the current user with IronPython?

  - by Ryan Montgomery

  I am trying to manage an IIS7 installation remotely using the Microsoft.Web.Administration library. I'm doing this in IronPython: import Microsoft.Web.Administration from Microsoft.Web.Administration import ServerManager manager = ServerManager.OpenRemote("RemoteServerName") for site in manager.Sites: print "Site: %(site)s" % { 'site' : site.Name } On the last line as it attempts to communicate with the remote server I get the following error: Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine devdealernetsvr failed due to the following error: 80070005. My research into the error lead me to believe that I do not have the proper credentials against the remote machine and so I would like to impersonate a user that does. I was hard pressed to find a way to do this with IronPython. Any help is much appreciated.

• Jsonp cross-domain ajax

  - by Guillaume le Floch

  I'm working on an application which use ajax call to get html from the server. When I run it on the server, everything works fine. But when I'm running on a localhost, I've a 'Access-Control-Allow-Origin' error. I looked arround and it seems like using jsonp could be the solution. So, my ajax call looks like that: $.ajax({ url: url, dataType: 'jsonp', crossDomain: true, type: 'GET', success: function(data){ // should put the data in a div }, error: function(){ //do some stuff with errors } }); I get html from the server, but I always have this error: Uncaught SyntaxError: Unexpected token < Is there a way to wrap the jsonp response in html? Thanks!
