  • Modifying SQL Database on Shared Hosting

    - by apocalypse9
    I have a live database on a shared hosting server. I am making some major changes to my site's code and I would like to fix some stupid mistakes I made in initially designing the database. These changes involve altering the size of a large number of fields, and enforcing referential integrity between tables properly. I would like to make the changes on both my local test server and the remote server if possible. I should note that while I'm fairly comfortable with writing complex queries to handle data, I have very little experience modifying database structure without a graphical interface. I can access the remote database in the visual studio database explorer but I can not use that for anything other than data manipulation. I installed Sql Management Studio express last night and after 40+ crashes I gave up - I couldn't even patch the damn thing. The remote server is SQL 2005 / The MyLittleAdmin web interface is available. So my question is what is the best way to accomplish these changes. Is there a graphical interface I can use on the remote server? If not is there an easy way to copy the database to my local machine, fix it, and re upload? Finally if none of the above are viable does anyone have links to a decent info on fixing referential integrity via query? Sorry for the somewhat general question - I feel like I am making this far harder than it should be but after searching / trying all night i haven't gotten anywhere. Thanks in advance for the help. I really appreciate it. ...Also does anyone have a time machine I can borrow- I need to go kick my past self's ass for this.

  • JavaScript method to write to Microsoft Visual Web Developer Debugger?

    - by Josh
    I generally test my web apps with Firefox and use Firebug. I love Firebug. But when I'm testing JavaScript code in IE I use the debugger in Microsoft's Visual Web Developer 2008 Express Edition. I would love to have an equivalent to Firebug's console.log methods which would allow me to log messages to Visual Web Developer. Any way to log messages to the error list/messages list/output pane using JavaScript?

  • MVC: Nested Views, and Controllers (for a website)

    - by incrediman
    I'm doing a PHP website using the MVC pattern. I am not using a framework as the site is fairly simple and I feel that this will give me a good opportunity to learn about the pattern directly. I have a couple questions. Question 1: How should I organize my views? I'm thinking of having a Page view which will have the header and footer, and which will allow for a Content view to be nested between them. Question 2: If I have 5 Content pages, should I make 5 different views that can be used as the content that is nested within the Page view? Or, should I make them all extend an abstract view called AbstractContent? Question 3: What about controllers? I think there should be one main controller at least. But then where does the request go from there? To another controller? Or should I just call the Page view and leave it at that? I thought that controllers were supposed to handle input, possibly modify a model, and select a view. But what if one of the views nested within the view that a controller calls requires additional input to be parsed? Question 4: Are controllers allowed to pass parameters into the view? Or should the controller simply modify the model, which will then affect the view? Or is the model only for DB access and other such things?

  • Select a Master Page in Web Developer Express

    - by JP
    The dialog box for adding a web form to a web project in Visual Studio has a checkbox to 'Select Master Page'. This checkbox doesn't exist in the Web Developer Express Edition. Is there a simple alternative to attach a Master Page while adding a new web form in the Express Version?

  • SQL: find entries in 1:n relation that don't comply with condition spanning multiple rows

    - by milianw
    I'm trying to optimize SQL queries in Akonadi and came across the following problem that is apparently not easy to solve with SQL, at least for me: Assume the following table structure (should work in SQLite, PostgreSQL, MySQL): CREATE TABLE a ( a_id INT PRIMARY KEY ); INSERT INTO a (a_id) VALUES (1), (2), (3), (4); CREATE TABLE b ( b_id INT PRIMARY KEY, a_id INT, name VARCHAR(255) NOT NULL ); INSERT INTO b (b_id, a_id, name) VALUES (1, 1, 'foo'), (2, 1, 'bar'), (3, 1, 'asdf'), (4, 2, 'foo'), (5, 2, 'bar'), (6, 3, 'foo'); Now my problem is to find entries in a that are missing name entries in table b. E.g. I need to make sure each entry in a has at least the name entries "foo" and "bar" in table b. Hence the query should return something similar to: a_id = 3 is missing name "bar" a_id = 4 is missing name "foo" and "bar" Since both tables are potentially huge in Akonadi, performance is of utmost importance. One solution in MySQL would be: SELECT a.a_id, CONCAT('|', GROUP_CONCAT(name ORDER BY NAME ASC SEPARATOR '|'), '|') as names FROM a LEFT JOIN b USING( a_id ) GROUP BY a.a_id HAVING names IS NULL OR names NOT LIKE '%|bar|foo|%'; I have yet to measure the performance tomorrow, but severly doubt it's any fast for tens of thousand of entries in a and thrice as many in b. Furthermore we want to support SQLite and PostgreSQL where to my knowledge the GROUP_CONCAT function is not available. Thanks, good night.

  • What's the easiest way to sort an EF4 EntityCollection<T>?

    - by Will
    I'd love to add some sorting to an EntityCollection that is bound to an ItemsControl (in xaml). I'd also like to do it as simply as possible. It appears that this is not possible. If I wrap the collection in a "sorted" version of the collection property within the Entity I lose collection change notifications. I can't use a CollectionViewSource because the entity collection's BindingListCollectionView does not support sorting for some goddamned reason (note: I've seen the blog post with the "dirty" hack to get around this, so please don't answer with that kthx). Is there a simple (couple lines of xaml, couple lines of code, whatever) way to achieve this??

  • How to set up source control in VS2010

    - by Jouke van der Maas
    Hi, I want to set up source control for my project, but it seems like I need a server for this. I've never done this before, and I couldn't find anything helpfull yet. Is there any way to host a server locally so Visual studio can use it? Or do you know any online (free) servers I can use? By the way, if source control is not actually what i should use for keeping track of changes in my files, please suggest a better option. Thanks in advance.

  • Best Embedded SQL DB for write performance?

    - by max.minimus
    Has anybody done any benchmarking/evaluation of the popular open-source embedded SQL DBs for performance, particularly write performance? I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons... Also, I'd be interested in the overall developer experience for any of these (for a Java app).

  • What is wrong with this Fortran '77 snippet?

    - by notJim
    I've been tasked with maintaing some legacy fortran code, and I'm having trouble getting it to compile with gfortran. I've written a fair amount of Fortran 95, but this is my first experience with Fortran 77. This snippet of code is the problematic one: CHARACTER*22 IFILE, OFILE IFILE='TEST.IN' OFILE='TEST.OUT' OPEN(5,FILE=IFILE,STATUS='NEW') OPEN(6,FILE=OFILE,STATUS='NEW') common/pabcde/nfghi When I compile with gfortran file.FOR, all lines starting with the common statement are errors (e.g. Error: Unexpected COMMON statement at (1) for each following line until it hits the 25 error limit). I compiled with -Wall -pedantic, but fixing the warnings did not fix this problem. The crazy thing is that if I comment out all 4 lines starting with IF='TEST.IN', the program compiles and works as expected, but I must comment out all of them. Leaving any of them uncommented gives me the same errors starting with the common statement. If I comment out the common statement, I get the same errors, just starting on the following line. I am on OS X Leopard (not Snow Leopard) using gfortran. I've used this very system with gfortran extensively to write Fortran 95 programs, so in theory the compiler itself is sane. What the hell is going on with this code?

  • Should a protected property in a C# child class hide access to a public property on the parent?

    - by Tim
    I have the following code: public class Parent { public string MyField { get; set; } } public class Child : Parent { protected new int MyField { get; set; } } I try and access this with: static void Main(string[] args) { Child child = new Child(); child.MyField = "something"; } Visual studio 2008 compiles this without comment, but under Mono (2.4.2, Ubuntu) I get the error message 'HideTest.Child.MyField' is inaccessible due to its protection level (CS0122) Is one implementation or the other more compliant with the standard here?

  • How to get started with tcp/ip v6?

    - by Johan
    Hi Now and then there is "news" about that the ip numbers will run out in X years, and we must change to tcp/ip v6... And even thou this crisis never really happens it has waken a question, how do you get started with tcp/ip v6? What can I do at home and is this a good or bad idea? Can you use IPv4 and IPv6 in the same cables in the same LAN, or do you need to physically separate them? Can you have some translation box so you can reach the "normal" internet from the IPv6 connected devices? (Just like a NAT-Router) Can someone please clarify the situation a little bit? Thanks Johan
