  • Deleteing cache upon submit

    - by user279521
    I have an asp.net web form (c#, .NET framework 3.5) that returns to itself after the user clicks the submit button. I think that some values of the form are cached (some controls in a "placeholder" are out of position... meaning they have moved slightly up or down on the web form). How can I delete the cache after user clicks submit, and ensure that the form reloads fresh, after submit?

  • C++[MSVC2010]: How does switch compile and how optimized and fast is it?

    - by ekul
    As I found out that I can use only numerical values in C++'s switch statements, I thought that there then must be some deeper difference between it and a bunch of if-else's. Therefore I asked myself: (How) does switch differ from if-elseif-elseif in terms of runtime speed, compile time optimization and general compilation? I'm mainly speaking of MSVC here.

  • What's the consequence when Core Data detects an optimistic locking failure when trying to save?

    - by dontWatchMyProfile
    I get it: When a managed object context saves, the snapshots of all edited objects are compared against the values in the persistent store to see if the PS has changed since the snapshot was made. If it did change, then there's a conflict and optimistic locking failed, according to Apple. But now, what's the consequence of this? What happens next? What are my options in this case?

  • Mocking ISession.Query<T>() for testing consumer

    - by TheCloudlessSky
    I'm trying to avoid using an in memory database for testing (though I might have to do this if the following is impossible). I'm using NHibernate 3.0 with LINQ. I'd like to be able to mock session.Query<T>() to return some dummy values but I can't since it's an extension method and these are pretty much impossible to test. Does anyone have any suggestions (other than using an in memory database) for testing session queries with LINQ?

  • finding elements with text using jQuery

    - by Tim Sheiner
    I want to create an array of all the html elements within a div that contain text strings, such as <p>some string</p>. I don't want to get hold of the strings, I want the array items to be the elements (in the example, would be the p node). I do not know before hand what the strings will be, so I can't look for string values to match. I also don't want empty text nodes to end up in the array. Thanks!

  • MySQL: How to do a conditional update?

    - by Tom
    Hi, I'm trying to a create an update statement along the following lines: TABLE car: id | owner_id | type | status An owner can have multiple cars. UPDATE car c SET c.type = 1 WHERE c.owner_id IN ($ids) AND c.status = [1 IF IT EXISTS, ELSE 0] $ids is reasonably small (under 50 values). It seems simple but I can't seem to get my head around it because I can't use a SELECT subquery with an UPDATE to the same table. Anyone? Thanks

  • How to avoid circular reference when excel cell update

    - by Nimo
    Hi, I'm writing a set of functions in c++ which can be called by excel. However, these functions are asynchronous, therefore no immediate return values available. Once a result is available I used a callback function through VBA which update the result to the relevant cell which called the functions. But, here I'm having circular function calling problem, because when I update the cell. excel automatically call the original function once again. Please help me to get around this problem Thank You
