This is what I have to split: 1 x3.1.105.41 1 -10 2 x4.1.105.41 0 -10 3 x12.1.105.41 0 -10 4 y3.1.105.41.19 1 0 5 y4.1.105.41.21 0 0 6 y1.1.105.41.23 0 0 7 y12.1.105.41.25 0 0 I would like to seperate each column.

• Do properties need to be deallocated?

  - by Sheehan Alam

  I subclassed NSObject: #import <Foundation/Foundation.h> @interface STObject : NSObject { NSString *message_type; NSString *twitter_in_reply_to_screen_name; } @property(nonatomic, copy) NSString *message_type; @property(nonatomic, copy) NSString *twitter_in_reply_to_screen_name; @end My implementation looks like: #import "STObject.h" @implementation STObject @synthesize message_type, twitter_in_reply_to_screen_name; @end Do I need to create a dealloc method for my two properties where I release the strings?

• c++ property class structure

  - by Without me Its just Aweso

  I have a c++ project being developed in QT. The problem I'm running in to is I am wanting to have a single base class that all my property classes inherit from so that I can store them all together. Right now I have: class AbstractProperty { public: AbstractProperty(QString propertyName); virtual QString toString() const = 0; virtual QString getName() = 0; virtual void fromString(QString str) = 0; virtual int toInteger() = 0; virtual bool operator==(const AbstractProperty &rightHand) = 0; virtual bool operator!=(const AbstractProperty &rightHand) = 0; virtual bool operator<(const AbstractProperty &rightHand) = 0; virtual bool operator>(const AbstractProperty &rightHand) = 0; virtual bool operator>=(const AbstractProperty &rightHand) = 0; virtual bool operator<=(const AbstractProperty &rightHand) = 0; protected: QString name; }; then I am implementing classes such as PropertyFloat and PropertyString and providing implementation for the comparator operators based on the assumption that only strings are being compared with strings and so on. However the problem with this is there would be no compiletime error thrown if i did if(propertyfloat a < propertystring b) however my implementation of the operators for each derived class relies on them both being the same derived class. So my problem is I cant figure out how to implement a property structure so that I can have them all inherit from some base type but code like what I have above would throw a compile time error. Any ideas on how this can be done? For those familiar with QT I tried using also a implementation with QVariant however QVariant doesn't have operators < and defined in itself only in some of its derived classes so it didn't work out. What my end goal is, is to be able to generically refer to properties. I have an element class that holds a hashmap of properties with string 'name' as key and the AbstractProperty as value. I want to be able to generically operate on the properties. i.e. if I want to get the max and min values of a property given its string name I have methods that are completely generic that will pull out the associated AbstactProperty from each element and find the max/min no matter what the type is. so properties although initially declared as PropertyFloat/PropertyString they will be held generically.

• MS SQL 2005: Why would a delete from a temp table hang forever?

  - by Dr. Zim

  DELETE FROM #tItem_ID WHERE #tItem_ID.Item_ID NOT IN ( SELECT DISTINCT Item_ID FROM Item_Keyword JOIN Keyword ON Item_Keyword.Keyword_ID = Keyword.Record_ID WHERE Keyword LIKE @tmpKW) The Keyword is %macaroni%. Both temp tables are 3300 items long. The inner select executes in under a second. All strings are nvarchar(249). All IDs are int. Any ideas? I executed it (it's in a stored proc) for over 12 minutes without it finishing.

• Converting different registry value types to string?

  - by Tom

  Hi, im traversing through the registry, taking the values of the keys and storing them as strings. I have discovered there are many different types. Some of these types are causing my filestream writer to fail. Is it possible to convert all of the below into a string form. The actual data value is not important, just the ability to differentiate between different values. DWORD ExpandString Binary (is this just the same as byte[] ?) MultiString

  - by CFP

  Hello world! Using the following code: Function GetSetting(Of T)(ByVal SettingName As String, ByRef DefaultVal As T) As T Return If(Configuration.ContainsKey(SettingName), CType(Configuration(SettingName), T), DefaultVal) End Function Yields the following error: Value of type 'String' cannot be converted to 'T'. Any way I could specify that in all cases, the conversion will indeed be possible (I'm basically getting integers, booleans, doubles and strings). Thanks!

• How would one go about adding (minor) syntactic sugars to Java?

  - by polygenelubricants

  Suppose I want to add minor syntactic sugars to Java. Just little things like adding regex pattern literals, or perhaps base-2 literals, or multiline strings, etc. Nothing major grammatically (at least for now). How would one go about doing this? Do I need to extend the bytecode compiler? (Is that possible?) Can I write Eclipse plugins to do simple source code transforms before feeding it to the standard Java compiler?

  Hi, in a C++ program some string reads info from file, and in some part contains a "\r" character. I need to remove it, afte the read, in order to avoid problems.

How would the problem be solved in C?

• Are L'A' and 'A' totally same?

  - by Benjamin

  When we write a program which supports both unicode and multibytes, we often use _T("some string") macro for strings. But, does a character also need to wrap this macro? Are L'A' and 'A' totally same? Don't we need to use _T('A') for a character?
