• On-screen keyboard not appearing when editing text fields in a UIWebView

  - by andrewebling

  I have a web view which displays a simple login form, containing username and password fields. However when the user clicks in one of the text fields, although the cursor appears in the text field, the on-screen keyboard does not appear. I've tried registering for UIKeyboardWillShowNotifications notifications and I see this notification arrive, however the keyboard doesn't actually appear on the screen. I've also tried sending the web view to the back of the view hierarchy and changing it's frame so it doesn't occupy the whole screen. However neither of these measures have solved the problem. What would people recommend trying next?

• Tomcat6 MySql JDBC Datasource configuration

  - by Bob

  Hi, I've always used Spring's dependency injection to get datasource objects and use them in my DAOs, but now, I have to write an app without that. With Spring I can write something like this: <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://127.0.0.1/app?characterEncoding=UTF-8" /> <property name="username" value="u" /> <property name="password" value="p" /> </bean> But how can I use datasource in my DAOs without Spring or anything? I'm using servlets and JSPs only. Performance is very important factor. Thanks in advance!

• How do you prevent brute force attacks on RESTful data services

  - by Adrian Grigore

  Hi, I'm about to implement an RESTful API to our website (based on WCF data services, but that probably does not matter). All data offered via this API belongs to certain users of my server, so I need to make sure only those users have access to my resources. For this reason, all requests have to be performed with a login/password combination as part of the request. What's the recommended approach for preventing brute force attacks in this scenario? I was thinking of logging failed requests denied due to wrong credentials and ignoring requests originating from the same IP after a certain threshold of failed requests has been exceeded. Is this the standard approach, or am I a missing something important? Thanks, Adrian

• Java .doc generation

  - by bozo

  Hi, anyone knows an easy method to generate mail merge .doc file from Java? So, I want to create a Word (95/97) document in Word, put some simple placeholders in it (only single value, no iterators and other advanced tags) like the ones used with mailmerge option, and then at runtime replace those placeholders with values from Java. One option is to use Jasperreports, but this would require that I create exact replica of non-trivial Word document in Jasper format, which is not easy and is hard to change later. Is there some method of filling placeholders in Word from Java, which does not require low-level document alteration with positioning and others low-level .doc tags from code, but something like this: docPreparer.fillPlaceholder('placeholder1', 'my real value from runtime'); Some CRMs do this via ActiveX control for internet explorer, and it works great (they use Word's mailmerge) but I need an all-Java solution. Ideas? Thanks, Bozo

• Documenting using Sandcastle: Refering to enum value using <see>

  - by brickner

  I'm using Sandcastle 2.4.10520 and Sandcastle Help File Builder 1.8.0 to generate a .chm help file. In my documentation, I'm using <see> tags. If I try to refer an enum like <see cref="NumberStyles"/> it works perfectly. If I try to refer an enum value like <see cref="NumberStyles.AllowTrailingWhite"/> I get a link in the documentation file, but the link leads me to an MSDN Page not found I don't get any warnings - my xml documentation is correct. I've noticed that MSDN pages that refer to an enum value also have a Page not found link. For example: UInt64.Parse Method (String, NumberStyles, IFormatProvider) refers to NumberStyles.AllowHexSpecifier and this leads to another MSDN Page not found. Should I refer to the enum instead of the enum value? What should I do to refer an enum? Is it even possible?

• Multilingual support using gettext with codeigniter, best practice?

  - by tobefound

  I know how to create .po files and how to generate .mo files and then use them for translation on my Codeigniter powered site. However, I'm not quite sure on how to change language from the site GUI. I want to stick to codeigniter's default url calling schema: www.domain.com/controllername/method/param1/param2. Calling the server like this is a no-brainer: www.domain.com/controllername?lang=en Doing that for every controller using the default url schema, requires me to implement the same method in every controller, just to pass the lang parameter to the setlocale() function and then bind to my .po domain name. Feels awkward... ANy ideas how you guys work with gettext in codeigniter? And yes, I do want to work with gettext.

• How do I determine that an instance of org.apache.poi.hwpf.model.ListData belongs to a numbered lis

  - by leighgordy

  Is there a way to determine if an instance of a org.apache.poi.hwpf.model.ListData belongs to a numbered list or bulleted list? I am using Apache Poi's org.apache.poi.hwpf.HWPFDocument class to read the contents of a word document in order to generate HTML. I can identify the list items in the document by checking to see that the paragraph I am working with is an instance of org.apache.poi.hwpf.model.ListData. I can not find a way to determine if ListData belongs to a bulleted list or a numbered list.

• Rails XML Builder - Code refactoring

  - by Vijay Dev

  I have written the following code in my Rails app to generate XML. I am using Aptana IDE to do Rails development and the IDE shows a warning that the code structure is identical in both the blocks. What changes can be done to the code to remove the duplicity in structure? Is there any other way to write the same? xml.roles do @rolesList.each do |r| xml.role(:id => r["role_id"], :name => r["role_name"]) end end xml.levels do @levelsList.each do |lvl| xml.level(:id => lvl["level_id"], :name => lvl["level_name"]) end end

• Efficiently check string for one of several hundred possible suffixes

  - by Ghostrider

  I need to write a C/C++ function that would quickly check if string ends with one of ~1000 predefined suffixes. Specifically the string is a hostname and I need to check if it belongs to one of several hundred predefined second-level domains. This function will be called a lot so it needs to be written as efficiently as possible. Bitwise hacks etc anything goes as long as it turns out fast. Set of suffixes is predetermined at compile-time and doesn't change. I am thinking of either implementing a variation of Rabin-Karp or write a tool that would generate a function with nested ifs and switches that would be custom tailored to specific set of suffixes. Since the application in question is 64-bit to speed up comparisons I could store suffixes of up to 8 bytes in length as const sorted array and do binary search within it. Are there any other reasonable options?

• Firing trigger for bulk insert

  - by Deepa

  ALTER TRIGGER [dbo].[TR_O_SALESMAN_INS] ON [dbo].[O_SALESMAN] AFTER INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for trigger here DECLARE @SLSMAN_CD NVARCHAR(20) DECLARE @SLSMAN_NAME NVARCHAR(20) SELECT @SLSMAN_CD = SLSMAN_CD,@SLSMAN_NAME=SLSMAN_NAME FROM INSERTED IF NOT EXISTS(SELECT * FROM O_SALESMAN_USER WHERE SLSMAN_CD = @SLSMAN_CD) BEGIN INSERT INTO O_SALESMAN_USER(SLSMAN_CD, PASSWORD, USER_CD) VALUES(@SLSMAN_CD, @SLSMAN_CD,@SLSMAN_NAME ) END END This is the trigger written for a table(O_SALESMAN) to fetch few columns from it and insert it into one another table(O_SALESMAN_USER). Presently bulk data is getting inserted into O_SALESMAN table through a stored procedure, where as the trigger is getting fired only once and O_SALESMAN_USER is having only one record inserted each time whenever the stored procedure is being executed,i want trigger to run after each and every record that gets inserted into O_SALESMAN such that both tables should have same count which is not happening..so please let me know what can be modified in this Trigger to achieve the same....

• Including a pyd directly in a setup.py file

  - by Philippe Beaudoin

  I have a complex build process to generate a couple of python extension modules (.pyd). I want to include these in my setup.py for use with distutils. The distutils page talks in length about how to add extension modules from source, but I'd want to simply package these precompiled .pyd. What is the best practice to do this? Eventually, I'd also like to freeze everything in an executable with py2exe. Will I be able to do this if I directly specify the .pyd?

• Entity framework and many to many queries unusable?

  - by John Landheer

  I'm trying EF out and I do a lot of filtering based on many to many relationships. For instance I have persons, locations and a personlocation table to link the two. I also have a role and personrole table. EDIT: Tables: Person (personid, name) Personlocation (personid, locationid) Location (locationid, description) Personrole (personid, roleid) Role (roleid, description) EF will give me persons, roles and location entities. EDIT: Since EF will NOT generate the personlocation and personrole entity types, they cannot be used in the query. How do I create a query to give me all the persons of a given location with a given role? In SQL the query would be select p.* from persons as p join personlocations as pl on p.personid=pl.personid join locations as l on pl.locationid=l.locationid join personroles as pr on p.personid=pr.personid join roles as r on pr.roleid=r.roleid where r.description='Student' and l.description='Amsterdam' I've looked, but I can't seem to find a simple solution.

• Handling update errors in multiple records in the TClientDataset's ReconcileError method

  - by Fabio Gomes

  I'm trying to use the ReconcileError event to allow the user to correct the data after an update error which occurred in a specific record among others. Example: I have a dataset with one field and 3 records, this field have a unique constraint on the database, then I change one value to conflict when it reaches the database, then I call ApplyUpdates on the Dataset. This will generate an error (violation of unique constraint) in the provider and abort the applyupdates process, returning raAbort in the Action var of the ReconcileError method. In the ReconcileError method I tryied to use: Action := HandleReconcileError(aDataSet, UpdateKind, E); ** EDIT ** After debugging and dumping the DataSet records which were returned from the server, I noticed that there are 2 records in this Dataset, the first is the Old record and the second have all the changes I made to the first record. I'm a bit confused, will I always get this DataSet with 2 records? I thought that it should have only one record with the Old/New values. Thanks.

• asp.net InsertCommand to return latest insert ID

  - by Stijn Van Loo

  Dear all, I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements. I have tried every possible solution in this thread http://forums.asp.net/t/990365.aspx but I'm still unsuccesfull, it always returns 1(=number of affected rows). I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs. As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows. Does anyone has a different take on this? Thanks in advance! Stijn

• How to create empty folders with maven archetype?

  - by chrsk

  There is an existing issue for this approach, located on Codehaus JIRA #ARCHETYPE-57, but all instructions listed in this ticket failed for me. Also the blog post of marekdec How to get maven archetype to generate empty directories fails for me. The trick within the archetype.xml with the trailing / doesnt works for me: <resources> <resource>src/main/webapp/</resource> Unable to find resource 'archetype-resources/src/main/webapp/' Also the fileSet directory in archetype-metadata.xml does not work for me: <fileSet filtered="true" encoding="UTF-8"> <directory>src/main/webapp/</directory> </fileSet> Is there any other solution? Or did i miss something? Thanks

• Use ASP.Net server control code generation from .ashx

  - by Matt Dawdy

  I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via AJAX client-side. HtmlTable errors out when I try to use the InnerHtml property (says it isn't supported), and when I try RenderControl, after making first a TextWriter and next an HtmlTextWriter object, I get the error that Page cannot be null. Has anyone done this before? Any suggestions?

• SSL_CTX_use_PrivateKey_file fail on Linux (part 2)

  - by Fredrik Ullner

  For some reason, my calls to OpenSSL's SSL_CTX_use_PrivateKey_file have started to fail (again) on Ubuntu. My previous post concerning this function; http://stackoverflow.com/questions/2028862/ssl-ctx-use-privatekey-file-fail-under-linux With the above fix, I have been able to use things fine until a couple of days ago. I have no idea why. The error string I'm now getting is error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib with 336265225 as error code. What is the problem? Additional info: The file passed to the function exist (SSL_CTX_use_certificate_file is passed the same file). The code in the callback function for the password is also not called (at least apparantly not according to the debugger). Everything works fine on Windows.

• Interacting with RESTful API's via Javascript?

  - by Alex

  Hi there, to start off, I know C++, C#, Python, some Ruby, and basic Javascript. Anyway, my question revolves around how to interact with RESTful API's via Javascript. I haven't been able to find any good examples on various websites, and so I've come here. So my basic question is: How do I interact with RESTful API's via JS? And where can I find out how to implement OAuth in JS? I know how to get my keys and such, just not how to actually code them in. Below is an example of a twitter API status update run from my MAC terminal with curl: curl -u username:password -d "my tweet" http://api.twitter.com/1/statuses/update.json How can I implement this in Javascript (preferably with OAuth authentication)? This would at least start me going in the right direction. Thanks so much!!

• Why image button dont work with forms in IExplorer 7+ ??? (Html)

  - by DomingoSL

  Hello guys, i have a web form who send post variables like: <form action="teacher.php" method="post"> <input name="pass" type="password"> <input name="quiere" type="image" value="submit" src="IMG/unlock-32.png" /> </from> In the same page i check for a submit acction with php doing a simple isset check like: "if (isset($_POST['quiere'])) {" But if you do this in IE the post var "QUIERE" (the button var) does not post, the others vars are fine, and if you try this simple form in any other browser it works. I only get this form function well in IE changing the button for a normal button, instead of a image button like: <input name="quiere" type="submit" value="submit" /> In this way, the var "quiere" get post. So, what do you think? and sorry for my english.

• Entity Framework and Sql Server view question

  - by Sergio Romero

  Hi to all, For several reasons that I don't have the liberty to talk about, we are defining a view on our Sql Server 2005 database like so: CREATE VIEW [dbo].[MeterProvingStatisticsPoint] AS SELECT CAST(0 AS BIGINT) AS 'RowNumber', CAST(0 AS BIGINT) AS 'ProverTicketId', CAST(0 AS INT) AS 'ReportNumber', GETDATE() AS 'CompletedDateTime', CAST(1.1 AS float) AS 'MeterFactor', CAST(1.1 AS float) AS 'Density', CAST(1.1 AS float) AS 'FlowRate', CAST(1.1 AS float) AS 'Average', CAST(1.1 AS float) AS 'StandardDeviation', CAST(1.1 AS float) AS 'MeanPlus2XStandardDeviation', CAST(1.1 AS float) AS 'MeanMinus2XStandardDeviation' WHERE 0 = 1 The idea is that the Entity Framework will create an entity based on this query, which it does, but it generates it with an error that states the following: "warning 6002: The table/view 'Keystone_Local.dbo.MeterProvingStatisticsPoint' does not have a primary key defined. The key has been inferred and the definition was created as a read-only table/view." And it decides that the CompletedDateTime field will be this entity primary key. We are using EdmGen to generate the model. Is there a way not to have the entity framework include any field of this view as a primary key? Thanks for help.
