  • Best database (mysql) structure for this case:

    - by robert
    we have three types of data (tables): Book (id,name,author...) ( about 3 million of rows) Category (id,name) ( about 2000 rows) Location (id,name) ( about 10000 rows) A Book must have at least 1 type of Category (up to 3) AND a Book must have only one Location. I need to correlate this data to get this query faster: Select Books where Category = 'cat_id' AND Location = 'loc_id' Select Books where match(name) against ('name of book') AND Location = 'loc_id' Please I need some help. Thanks

  • Drawbacks of using an integer as a bitfield?

    - by Mark
    I have a bunch of boolean options for things like "accepted payment types" which can include things like cash, credit card, cheque, paypal, etc. Rather than having a half dozen booleans in my DB, I can just use an integer and assign each payment method an integer, like so PAYMENT_METHODS = ( (1<<0, 'Cash'), (1<<1, 'Credit Card'), (1<<2, 'Cheque'), (1<<3, 'Other'), ) and then query the specific bit in python to retrieve the flag. I know this means the database can't index by specific flags, but are there any other drawbacks?

  • How can I add reflection to a C++ application?

    - by Nick
    I'd like to be able to introspect a C++ class for its name, contents (i.e. members and their types) etc. I'm talking native C++ here, not managed C++, which has reflection. I realise C++ supplies some limited information using RTTI. Which additional libraries (or other techniques) could supply this information?

  • Object or primitive type

    - by John
    Hi, Can someone explain to me the usage of Integer, Boolean etc in place of their primitive types in JAVA? I can't seem to grasp the advantages their are providing. They seem to create unnecessary problems of handling null values. Thanks!

  • Convert Java.Util.HashMap to System.Collections.IDictionary

    - by Paul
    In Xamarin I've got a .jar I've imported using a Java Binding Library. One of the callbacks has a Java.Lang.Object parameter which gives me Java.Util.HashMap and Java.Util.ArrayList at runtime. I'm abstracting this SDK behind a cross-platform interface, so I need to convert this to a .NET type. It there anything like the ArrayAdapter except in reverse that can convert the Java types to their .NET equivalents?

  • How do I control the amount of JavaScript Ajax Control Toolkit spits out?

    - by RyanKeeter
    With the Ajax Control Toolkit, one can easily drag and drop all types of great extender onto controls, but they register a boatload of JavaScript to do it. How do I control this? If the ScriptManager is in the MasterPage, is there anyway to control the loading of a script on one page that isn't in another? For example: calendar extender is on one page, but the script for it gets loaded on every page that is a child of the master page.

  • How can I extend Eclipse Java search to JSPs?

    - by benhsu
    Friends, Our JSP code uses both Spring form tags and JSTL tags. Is there a way that when I search for getFoo() in the Eclipse Java Search, for Eclipse to also return uses of the foo property in the JSP files? I suspect the answer is "no", because there isn't a way at compile time to tell the types of the JSP beans, but its worth asking, right?

  • C# Dictionary<> and mutable keys

    - by Pierreten
    I was told that one of the many reasons strings were made immutable in the C# spec was to avoid the issue of HashTables having keys changed when references to the string keys altered their content. The Dictionary< type allows reference types to be used as a key. How does the dictionary avoid the issue of altered keys that lead to "misplaced" values? Is there a memberwise clone made of an object when used as a key?

  • Class destructor memory handling in C++

    - by wyatt
    What potential memory leaks won't an implicit destructor handle? I know that if you have anything stored on the heap it won't handle it, and if you have a connection to a file or a database, that needs to be handled manually. Is there anything else? What about, say, non-base data types like vectors? Also, in an explicit destructor, need you destroy non-heap variables which would have been destroyed by the implicit, or are they handled automatically? Thanks

  • Can i use a generic implicit or explicit operator? C#

    - by acidzombie24
    How do i change the following statement so it accepts any type instead of long? Now here is the catch, if there is no constructor i dont want it compiling. So if theres a constructor for string, long and double but no bool how do i have this one line work for all of these support types? ATM i just copied pasted it but i wouldnt like doing that if i had 20types (as trivial as the task may be) public static explicit operator MyClass(long v) { return new MyClass(v); }

  • what are LPARAM and WPARAM defined as

    - by Mark Heath
    I know I'm being lazy here and I should trawl the header files for myself, but what are the actual types for LPARAM and WPARAM parameters? Are they pointers, or four byte ints? I'm doing some C# interop code and want to be sure I get it working on x64 systems.

  • Can the .NET MethodInfo cache be cleared or disabled?

    - by Anton
    Per MSDN, calling Type.GetMethods() stores reflected method information in a MemberInfo cache so the expensive operation doesn't have to be performed again. I have an application that scans assemblies/types, looking for methods that match a given specification. The problem is that memory consumption increases significantly (especially with large numbers of referenced assemblies) since .NET hangs onto the method metadata. Is there any way to clear or disable this MemberInfo cache?
