  • Make a table row's text editable immediately

    - by Ricky
    I have an NSTableView in my user interface, where new rows are added when the user presses a button or keyboard shortcut. Each row consists of two text cells (the table is comprised of two columns). Is there a way to immediately select the first text cell of a new row which is added? So, basically, I would like the user to be able to press the button, adding a new row to the table and then having it editable straight away.

  • Confusion over C++ new operator and classes

    - by Nils
    Hi all I created a simple class in C++ which has a private dynamic array. In the constructor I initialize the array using new and in the destructor I free it using delete. When I instantiate the class using Class a = Class(..); it works as expected, however it seems I cannot instantiate it using the new operator (Like Class *a = new Class(..);), I always get a segmentation fault. What I don't understand is when I should use new to instantiate a class and when just call the constructor or should it be possible to instantiate a class either with new or by just calling the constructor. float** A = new float*[3]; for (int i=0; i<3; i++) { A[i] = new float[3]; } A[0][0] = 3; A[0][1] = 3; A[0][2] = 4; A[1][0] = 5; A[1][1] = 6; A[1][2] = 7; A[2][0] = 1; A[2][1] = 2; A[2][2] = 3; Matrix *M = new Matrix(A, 3, 3); delete[] A; delete M; Below the class definition.. class Matrix { private: int width; int height; int stride; float* elements; public: Matrix(float** a, int n, int m); ~Matrix(); }; Matrix::Matrix(float** a, int n, int m) { // n: num rows // m: elem per rows elements = new float[n*m]; for (int i=0; i<n; i++) { for (int j=0; j<m; j++) { elements[i*n + j] = a[n][m]; } } } Matrix::~Matrix() { delete[] elements; }

  • SQL Query Theory Question...

    - by Keng
    I have a large historical transaction table (15-20 million rows MANY columns) and a table with one row one column.

  • Help with simple query - why isn't an index being used?

    - by Randy Minder
    I have the following query: SELECT MAX([LastModifiedTime]) FROM Workflow There are approximately 400M rows in the Workflow table. There is an index on the LastModifiedTime column as follows: CREATE NONCLUSTERED INDEX [IX_Workflow_LastModifiedTime] ON [dbo].[Workflow] ( [LastModifiedTime] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) The above query takes 1.5 minutes to execute. Why wouldn't SQL Server use the above index and simply retrieve the last row in the index to get the maximum value? Thanks.

  • Declare java enum with a String array

    - by chama
    I'm trying to declare an enum type based on data that I'm retrieving from a database. I have a method that returns a string array of all the rows in the table that I want to make into an enumerated type. Is there any way to construct an enum with an array? This is what I tried, but from the way it looked in eclipse, it seemed like this just created a method by that name: public enum ConditionCodes{ Condition.getDescriptions(); } Thank you in advance!

  • How to test if a table is empty, using Hibernate

    - by landon9720
    Using Hibernate, what is the most efficient way to determine if a table is empty or non-empty? In other words, does the table have 0, or more than 0 rows? I could execute the HQL query select count(*) from tablename and then check if result is 0 or non-0, but this isn't optimal as I would be asking the database for more detail than I really need.

  • Large Table in iFrame crashes IE8

    - by Brian
    I have a page with an iFrame whose source is an ashx page. The handler takes in 3 arguments through the query string and generates a text/html response containing a table. When the table gets 1700 rows it crashes the IE8 browser. The browser freezes and returns a null reference error. If I take the html that is being rendered and place it inside a DIV on the page it renders fine in IE8. Any suggestions?
