• How do I remove a control if not a specific type?

  - by joek1975

  I have a control that I need to restrict the types of child controls that it can contain during design time (dragging a new control onto an existing control on the form designer). I tried to do this by overriding the OnControlAdded event: Protected Overrides Sub OnControlAdded(ByVal e As System.Windows.Forms.ControlEventArgs) MyBase.OnControlAdded(e) If e.Control.GetType() IsNot GetType(ExpandablePanel) Then MsgBox("You can only add the ExpandablePanel control to the TaskPane.", MsgBoxStyle.Exclamation Or MsgBoxStyle.OkOnly, "TaskPane") Controls.Remove(e.Control) End If End Sub This seems to work, however I get an error message from Visual Studio immediately after the control is removed: 'child' is not a child control of this parent. What does this mean? How can I accomplish this without errors occurring?

• How to make large List & Label template?

  - by codymanix

  We want to have a form which contains lots of fields one over another. All of them are passed as parameters to the form. There are many condition formulas which determine whether one element is shown or not. Depending on how many fields are shown the result will get a different number of pages. The problem is, that the designer will only allow us to design on on single page with a fixed height. But we need more space to place fields there, because they are too many of them. Is there a way to enlarge the designer working area? Sure, a possible workaround is to choose a large paper format when in dessiger which will enlarge the working area and then reset it to A4 (Standard paper format), but even this will not be enough for us in some cases. Does nobody know an answer?

• sIFR 3 - sifr-config.js possibly not running? Not sure what's wrong.

  - by nukegara

  Hi, I've been messing with this for a few hours, and I just can't get the text to be replaced at all. I really can't believe it's taking so long, especially because I did this a few months ago and got it to work in minutes. Anyway, here is my site I'm working on: http://www.moreheadplanetarium.org/regeneration/test/vision.php and I want to replace the h1 tag (Morehead's Vision). I don't know what's wrong, since I've done everything I know to do. I'm jumping back into web design and using Firebug, and when I check the scripts it only has sifr.js and sifr-debug.js in the list, so I'm assuming the config isn't loading but I have no idea what could be the hold up... How do you get the debug to work btw? thanks!

• delegating into private parts

  - by FredOverflow

  Sometimes, C++'s notion of privacy just baffles me :-) class Foo { struct Bar; Bar* p; public: Bar* operator->() const { return p; } }; struct Foo::Bar { void baz() { std::cout << "inside baz\n"; } }; int main() { Foo::Bar b; // error: 'struct Foo::Bar' is private within this context Foo f; f->baz(); // fine } Since Foo::Bar is private, I cannot declare b in main. Yet I can call methods from Foo::Bar just fine. Why the hell is this allowed? Was that an accident or by design?

• Python configuration file generator

  - by Stan

  I want to use Python to make a configuration file generator. My roughly idea is feeding input with template files and some XML files with the real settings. Then use the program to generate the real configuration files. I got several questions: Is there any open source configuration generator program? (what could be the keyword), I wonder if there's anything can be added/modified in the design. Does Python have good XML parser module? Is it good idea to use XML file to save the original settings? I've been thinking to use Excel since it's more intuitive to maintain, but harder for program to parse. Not sure how people deal with this. Hope the community can give me some suggestions. Thanks a lot!

• Scala puts precedence on implicit conversion over "natural" operations... Why? Is this a bug? Or am

  - by Alex R

  This simple test, of course, works as expected: scala var b = 2 b: Int = 2 scala b += 1 scala b res3: Int = 3 Now I bring this into scope: class A(var x: Int) { def +=(y:Int) { this.x += y } } implicit def int2A(i:Int) : A = new A(i) I'm defining a new class and a += operation on it. I never expected this would affect the way my regular Ints behave. But it does: scala var b:Int = 0 b: Int = 0 scala b += 1 scala b res29: Int = 0 scala b += 2 scala b res31: Int = 0 Scala seems to prefer the implicit conversion over the natural += that is already defined to Ints. That leads to several questions... Why? Is this a bug? Is it by design? Is there a work-around (other than not using "+=")? Thanks

• What CSS attribute stops my site squidging up?

  - by SLC

  I am looking at a website on the internet with the standard centered box design (the entire site is centered in a box and has a border each side). As you shrink it, the border gets smaller but the content stays the same size. This is fine. However on their site, once you get smaller still, you simply get scrollbars. The content remains untouched. On my site if you do this, things like text and links start to scroll onto multiple lines and the whole site gets broken. How can I keep it the same even when the viewport is small?

• VS 2008, is there a way to search properties like the old vb6/EVB? CTRL+SHIFT?

  - by Davery

  I really miss the CTRL+SHIFT+CHAR searching of a property in VS 2008 that older IDE's had... typing CTRL+SHIFT+T got you to "tabindex" then Tag when pressed again. They dropped it in VS 2002 I believe, and the closest I could find to restoring any functionality like it was acorn's property window filter, which isn't exactly functional. Does anyone know of a way to get this functionality back? I hate having to browse through 30-40 properties in design mode, when a CTRL+SHIFT+T would get me right to text. Thanks!

• How to pass sockets created to another Java Process

  - by whoi

  Hi; We have an application which creates many sockets which belongs to its thread, By design if this application somehow fails, all threads stop which is not wanted. So to overcome this issue, each thread must be separated from the main application, if one of the threads fails, the other ones should be running. One thing in our mind is to pass created socket to another java process, so what is the correct way? An other approach also is welcome? Waiting for your suggestions...

• wordpress: previous_post_link() / next_post_link() placeholder

  - by superUntitled

  I am having trouble with the previous_post_link() and next_post_link() functionality. When there is no previous post, the function previous_post_link() does not display a link, likewise for the next_post_link() and the last post. I would like to have a placeholder image so that the design stays consistent. Currently I have images of green arrows pointing left and right, I would like to place an image of a grey arrow if there are no more posts to go back to. Is there a way to use the next_post_link()/previous_post_link() functions but not have the link removed. I also wonder if there is a way for the links to cycle, so that if you come to the most recent post, the next post link would bring you back to the first post.

• How to filter/sort/rank object model nodes?

  - by BCS

  I have some kind of object model and I need to filter and sort it's nodes for some kind of property. What kinds of automated systems exist to generate and select properties of the object model that correlate to what I want? (I'm intentionally being abstract and non-specific) I'm thinking of a system that works kind of like spam filters or supervised classification systems in that given an example data set it identifies rules that find nodes of interest. However I'm looking for a more general system in that it shouldn't require any design time information about the object model. It should work equality well as a spam filter on e-mail, a bug finder on a code base, an interest filter in a newsgroup or bot accounts finder on a social networking site. As long as it can explore the object model via reflection and be given a set of "interesting" nodes, it should be able to find rules that will find more nodes like them.

• height: auto does not work to automatically resize header

  - by slevin

  I'm trying to do a simple thing in CSS I have a header tag and inside that a couple of h tags. So, in order to have a responsive design I do height:auto; inside the header tag, so it will automatically stretch to contain the h tags. Right? But does not work, headeris just a line in the top of the page. t should stretch to contain the titles, right? What am I missing? Is it a good practice to put CSS in the h tags and not style header at all? So h tags will be like the header in user's eye? Thanks in advence Check it here

• how to call functions/methods within CMS block or page?

  - by latvian

  Hi, We are trying to make all our blocks and pages static so that designer or anyone else can easily change the content or design of the website, however. There is a feature that uses our own custom module. So, the template that we want to make static is calling methods out of our custom block, for example, <!--some html code--> ..... <?php $this->helpMeBePartOfCMS(); ?> ..... <!--some html code--> How do i incorporate these method calls inside cms block or page? Thank you

• Dataset Binding stored procedures update/insert/delete

  - by Jin

  Hi all, I am currently having a problem since the DB has been changed. I am using Datasets for a c# application, and there is a user management system. For the security issues, our current DB design is like user log into app. DB returns a session ID On use of any other stored procedures, a session ID must be specified. BUT, the DB didn't request session ID before. since I am using the datasets, I used update/insert/delete stored procedures with "TableAdaptor Configuration Wizard". Bind Commands to Existing Stored Procedures (choose stored procedures to call and specify any reuiqred parameters) Now, it seems like I have to specify session ID for Insert/Update/Delete stored procedures. How do I specify session ID parameter here? It seems like I have to pick one return parameter variable from a select statement. Thanks,

• C++ Iterators and inheritance

  - by jomnis

  Have a quick question about what would be the best way to implement iterators in the following: Say I have a templated base class 'List' and two subclasses "ListImpl1" and "ListImpl2". The basic requirement of the base class is to be iterable i.e. I can do: for(List<T>::iterator it = list->begin(); it != list->end(); it++){ ... } I also want to allow iterator addition e.g.: for(List<T>::iterator it = list->begin()+5; it != list->end(); it++){ ... } So the problem is that the implementation of the iterator for ListImpl1 will be different to that for ListImpl2. I got around this by using a wrapper ListIterator containing a pointer to a ListIteratorImpl with subclasses ListIteratorImpl2 and ListIteratorImpl2, but it's all getting pretty messy, especially when you need to implement operator+ in the ListIterator. Any thoughts on a better design to get around these issues?

• How do I "think in AngularJS" if I have a jQuery background?

  - by Mark Rajcok

  How do I “think in AngularJS” if I have a jQuery background? Suppose I'm familiar with developing client-side applications in jQuery, but now I'd like to start using AngularJS. Can you describe the paradigm shift that is necessary? Here are a few questions that might help you frame an answer: How do I architect and design client-side web applications differently? What is the biggest difference? What should I stop doing/using; what should I start doing/using instead? Are there any server-side considerations/restrictions? I'm not looking for a detailed comparison between jQuery and AngularJS.

• One application instance for two domain name

  - by dervlap

  Hello, I have two web applications in ASP.NET which are quite the same (same business logic, same DAL, same DB scheme but different instance). The only thing that I need to change is the design (logo, color,...) and the text (global and local resource) to adress two separate business sector. We cannot "subdomain" the application because we need the two app "seems to be" independant. Is it a good idea to run only one instance for the 2 web applications. For example : I will have 2 hostnames : mycompagny.com and mycompagny2.com and I will put an HTTP Module which will set a string which will be propagated in my application like 'company' and 'company2'. I will instanciate the dal only once but the connection string will change depending on the string 'company' or 'company2'. Any pros and cons ? Any other alternatives ?

• Just how much do I want to make virtual?

  - by Alex

  I am writing an abstract superclass where literally every method is going to be overridden. There is some default functionality I could implement, but most of the time it's enough to leave the implementation to the subclass writer. Since just about every method is going to be overwritten, how much should I make virtual and how much should I just leave as regular methods? In the current incarnation, everything is virtual, but I still haven't let this loose to anyone to use, so the design is flexible. What advantages/disadvantages are there to virtual functions? Links to good reading material about this would be appreciated.

• JUnit Theories: Why can't I use Lists (instead of arrays) as DataPoints?

  - by MatrixFrog

  I've started using the new(ish) JUnit Theories feature for parameterizing tests. If your Theory is set up to take, for example, an Integer argument, the Theories test runner picks up any Integers marked with @DataPoint: @DataPoint public static Integer number = 0; as well as any Integers in arrays: @DataPoints public static Integer[] numbers = {1, 2, 3}; or even methods that return arrays like: @DataPoints public static Integer[] moreNumbers() { return new Integer[] {4, 5, 6};}; but not in Lists. The following does not work: @DataPoints public static List<Integer> numberList = Arrays.asList(7, 8, 9); Am I doing something wrong, or do Lists really not work? Was it a conscious design choice not to allow the use Lists as data points, or is that just a feature that hasn't been implemented yet? Are there plans to implement it in a future version of JUnit?

• Compare two integer arrays with same length

  - by meta

  [Description] Given two integer arrays with the same length. Design an algorithm which can judge whether they're the same, the definition of "same" is that, if these two arrays are in sorted order, the elements in corresponding position should be the same. [Example] <1 2 3 4> = <3 1 2 4> <1 2 3 4> != <3 4 1 1> [Limitation] The algorithm should require constant extra space, and O(n) running time.

• What is the best way to partition large tables in SQL Server?

  - by RyanFetz

  In a recent project the "lead" developer designed a database schema where "larger" tables would be split across two seperate databases with a view on the main database which unioned the two seperate database-tables together. The main database is what the application was driven off of so these tables looked and felt like ordinary tables (except some quirkly things around updating). This seemed like a HUGE performance problem. We do see problems with performance around these tables but nothing to make him change his mind about his design. Just wondering what is the best way to do this, or if it is even worth doing?

• Choosing an alternative ( visual basic) high level programming language

  - by user370244

  I used to be visual basic 6 programmer, i was pleased with visual basic : it is high level language that do stuff fast,easy to learn, easy to do stuff in,you can drag and drop stuff to the form and write your code,it is simply amazing.however microsoft buried VB6 and pointed us to VB.NET which is so different that it is not the old VB anymore.I didn't like what microsoft did and would like to look somewhere AWAY from microsoft and from any other proprietary language . I would like to look into a similar language that is easy,cross platform (windows / Linux), object oriented, visual design, non proprietary and compile (for some guarding against reverse engineering). i am freelancer so the choice is entirely mine,i don't care about performance of programs, the time taken to develop a given programs is much more important. desktop / database / GUI /networking programming is what i am looking for. so any such language offered by our open source community ? thank you so much

• Mongodb, simple IN problem

  - by afvasd

  Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?
