• Referencing control on one form from another form VB.NET

  - by Tom

  My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

• PHP: How to overwrite values in one array with values from another

  - by Svish

  I have an array with default settings, and one array with user-specified settings. I want to merge these two arrays so that the default settings gets overwritten with the user-specified ones. I have tried to use array_merge, which does the overwriting like I want, but it also adds new settings if the user has specified settings that doesn't exist in the default ones. Is there a better function I can use for this than array_merge? Or is there a function I can use to filter the user-specified array so that it only contains keys that also exist in the default settings array? (PHP version 5.3.0)

• One account, multiple users, multiple shopping cart in a web application

  - by lemotdit

  I received a somewhat unusual request (imo) for a transactional web site. I have to implement the possibility of having multiple shopping cart for the same user. Those really are shopping carts, not order templates. I.E: A store with several departments ordering under the same account, but with a different person placing orders for a specific department only. Having more than one user per account is not an option since it would involve 'too much' management from the stores owner and the admins. Anyone had to deal with this before? The option so far is to have names for shopping cart, and a dropdown list or something alike after login to choose the cart with some kind of 'busy flag' to lock the cart if it's in use in another session.

• Regular Expression: Allow letters, numbers, and spaces (with at least one letter or number)

  - by makeee

  I'm currently using this regex ^[A-Z0-9 _]*$ to accept letters, numbers, spaces and underscores. I need to modify it to require at least one number or letter somewhere in the string. Any help would be appreciated! This would be for validating usernames for my website. I'd actually like to support as many characters as I can, but just want to ensure that I prevent code injection and that characters will display fine for all users. So I'm definately open to regex validation suggestions that would support a wider set of characters.

• Can an appdomain be restricted to one directory?

  - by Caerbanog

  I am developing a plugin host. The plugins should have as little trust as they need, however I want to have the possibility for a plugin to read and write files. Can the AppDomain where the assembly will be loaded be restricted to have access to only one directory for reading and writing? Other options and ways to go about this are also appreciated like for example easy ways to stream file data from the host to the plugin (reading) and from the plugin to the host (writing). If its relevant: I am using the MAF infrastructure for the plugins. http://msdn.microsoft.com/en-us/library/bb384200.aspx

• ASP MVC ViewData from one view to another (Html.Encode())

  - by Jacob Huggart

  Hello all, I have a page with a bunch of labels and checkboxes on it. On this page, the labels need to be easily customizable after the project is deployed. So I made all of the labels in this style: Html.Encode(ViewData["lblText"]) And I added a button on the page called "Edit Button Labels" that will only be seen by admins. When that button is clicked, I would like to load another view that simply contains a table of two columns. One column needs to contain the current labels and the other should have text boxes for the user to enter new labels. Then, once any changes have been made, I need to permanently change the "lblText" for each label on the original page. I have tried passing viewdata and tempdata to the "Edit Button Labels" view using both return view() and return RedirectToAction() with no success. Am I missing something minor or is there a better way to do this?

• Fast way to pass a simple java object from one thread to another

  - by Adal

  I have a callback which receives an object. I make a copy of this object, and I must pass it on to another thread for further processing. It's very important for the callback to return as fast as possible. Ideally, the callback will write the copy to some sort of lock-free container. I only have the callback called from a single thread and one processing thread. I only need to pass a bunch of doubles to the other thread, and I know the maximum number of doubles (around 40). Any ideas? I'm not very familiar with Java, so I don't know the usual ways to pass stuff between threads.

• Hudson results one step behind

  - by kaerast

  I'm using the filesytem plugin for Hudson, and when a build happens it looks for new/modified files, copies them to the Workspace, runs tests using Rake, and then publishes those junit xml result files. However, the updated junit xml result files don't get pushed to the workspace until the next build. This means that when the publishing of the junit xml result files happens, it's always one step behind. And this means I need to run a build twice before the results show. The Rake task is creating the junit xml files in the project directory. I've tried outputting to the workspace directory, but it seems to make things worse and the results don't get published at all. Am I doing something fundamentally wrong here? Is there a simple way of getting those junit xml results pushed to the workspace so that the post-build "Publish JUnit test result report" actually runs against the newly created xml files?

• Copying files from one directory to another in Java

  - by user42155

  Hello, I want to copy files from one directory to another (subdirectory) using Java. I have a directory, dir, with text files. I iterate over the first 20 files in dir, and want to copy them to another directory in the dir directory, which I have created right before the iteration. In the code, I want to copy the review (which represents the ith text file or review) to trainingDir. How can I do this? There seems not to be such a function (or I couldn't find). Thank you. boolean success = false; File[] reviews = dir.listFiles(); String trainingDir = dir.getAbsolutePath() + "/trainingData"; File trDir = new File(trainingDir); success = trDir.mkdir(); for(int i = 1; i <= 20; i++) { File review = reviews[i]; }

• How to insert into a table with just one IDENTITY column (SQL Server CE)

  - by Hei

  Hello I am trying to insert a value in a one IDENTITY column Table in SQL Server CE 3.5. I Tried the following: INSERT Target DEFAULT VALUES INSERT Target (ID) VALUES (DEFAULT) INSERT Target (ID) VALUES () But none of them worked. This is the SQL command I used to create the table (Using SQL Server Management Studio): CREATE TABLE Target( ID int NOT NULL IDENTITY (1, 1) PRIMARY KEY ); Microsoft help site (http://msdn.microsoft.com/en-us/library/ms174633%28SQL.90%29.aspx) mentions that DEFAULT values are not valid for identity columns however they do not mention any alternative. They mention something about uniqueidentifier and ROWGUID but I have not been able to make it work. I would appreciate any pointers on how to solve this problem or links to documentation about valid sql commands for sql server CE. Thank you

• Rails group validation with just one error message

  - by Victor

  The following validation code in the model: validates :formatted_address, :zip, :city, :state, :country, :presence => true, :message => "is incomplete. Please enter full address." is displayed when either of the fields are empty. Let's say now :address and country are empty, 2 errors are displayed: Formatted Address is incomplete. Please enter full address. Country is incomplete. Please enter full address. How can I group the error message in the validation to just show one error message if either of the fields validated does not exist? Address is incomplete. Please enter full address. Thanks.

• move data from one table to another, postgresql edition

  - by IggShaman

  Hi All, I'd like to move some data from one table to another (with a possibly different schema). Straightforward solution that comes into mind is - start a transaction with serializable isolation level; INSERT INTO dest_table SELECT data FROM orig_table,other-tables WHERE <condition>; DELETE FROM orig_table USING other-tables WHERE <condition>; COMMIT; Now what if the amount of data is rather big, and the <condition> is expensive to compute? In PostgreSQL, a RULE or a stored procedure can be used to delete data on the fly, evaluating condition only once. Which solution is better? Are there other options?

• How does one refer to the game1 class's variables in XNA

  - by user1149068

  I try to refer to an array in the Game1 class by creating an object of the Game1 class with its definition Game1 gameObject; , its declaration gameObject = new Game1(); in the constructor, and its usage gameObject.tileArray[xInt, yInt].treed = true;. The game1 class itself remains unchanged in its class code other than some methods and variables. When I try to use this code in the TreeRegion class it gives me "Object reference not set to an instance of an object," leading me to believe that the game1 class is null somehow. How might one change the class or object in order to refer to game1's variables? Mind you I am self-taught and still rather new to C#. The class that refers to game1: http://pastebin.com/0chEcKfq Game1 itself http://pastebin.com/zLDVzCca

• Codeigniter setting multiple where conditions, how to unset one

  - by Dustin

  I've got a script that is a notify_url from paypal that is supposed to update multiple tables in my database using the following code: //update first table $this-db-where('someid', $somid); $this-db-update('table', $data); ///update second table $this-db-where('somesecondid', $somesecondid) $this-db-update('anothertable', $data2); Then I get the following error: Unknown column 'somesecondid' in 'where clause' UPDATE anothertable SET avail = 0 WHERE someid = '13' AND somesecondid = '199' So codeigniter is combining those where clauses into a single query. Is there a way to unset the first one so it only has "UPDATE anothertable SET avail=0 WHERE somesecondid = 199" ? Thanks!

• Git: Make one branch exactly like another

  - by G. Martin

  I am relatively new to Git, and I'm still not very comfortable with it. Right now, I'm looking for the command/options/magic that can make the current branch look like another branch; that is, to merge them, but when a conflict arises, to always choose the difference in the branch that is being merged into the current one. My situation is thus; I have an stable(ish) application on the "master" branch. I also have another branch, called "feature". I basically want to make changes/additions/deletions to feature until I like the new feature I'm working on. Once I feel it is ready, I want to make the master branch look identical to the feature branch. I know this probably isn't a best practice, but as I said, I'm new to Git. I plan on learning how to do more complicated things in the future, but for now, this is all I need. Thanks, SO!

• XPath : finding an attribute node (and only one)

  - by subtenante

  What is the XPath to find only ONE node (whichever) having a certain attribute (actually I'm interested in the attribute, not the node). For example, in my XML, I have several tags having a lang attribute. I know all of them must have the same value. I just want to get any of them. Right now, I do this : //*[1][@lang]/@lang, but it seems not to work properly, for an unknown reason. My tries have led me to things ranging from concatenation of all the @lang values ('en en en en...') to nothing, with sometimes inbetween what I want but not on all XML. EDIT : Actually //@lang[1] can not work, because the function position() is called before the test on a lang attribute presence. So it always takes the very first element found in the XML. It worked best at the time because many many times, the lang attribute was on root element.
