• Add/Edit Columns in DataBound DataGrid

  - by Dave

  I've got a datagrid that is databound from a database table. How do I: a) Edit the displayed value for a column using the values from other columns in the row? (For example, display a URL like: <a href="/url?param=columnA">columnB</a> where columnA is the value from column A and columnB is the value from columnB) b) Add an additional column using values from the other columns (similar to a.)

• Problem intialising 2D array

  - by TeeJay

  Ok, so I have a 2D Array that is initialised with values from a file (format: x y z). My file reads in the values correctly but when adding the z value to the matrix/2DArray, I run into a segfault and I have no idea why. It is possibly incorrect use of pointers? I still don't quite have the hang of them yet. This is my intialiser, works fine, even intialises all "z" values to 0. int** make2DArray(int rows, int columns) { int** newArray; newArray = (int**)malloc(rows*sizeof(int*)); if (newArray == NULL) { printf("out of memory for newArray.\n"); } for (int i = 0; i < rows; i++) { newArray[i] = (int*)malloc(columns*sizeof(int)); if (newArray[i] == NULL) { printf("out of memory for newArray[%d].\n", i); } } //intialise all values to 0 for (int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { newArray[i][j] = 0; } } return newArray; } This is how I call the initialiser (and problem function). int** map = make2DArray(rows, columns); fillMatrix(&map, mapFile); And this is the problem code. void fillMatrix(int*** inMatrix, FILE* inFile) { int x, y, z; char line[100]; while(fgets(line, sizeof(line), inFile) != NULL) { sscanf(line, "%d %d %d", &x, &y, &z); *inMatrix[x][y] = z; } } From what I can gather through the use of ddd, the problem comes when y gets to 47. The map file has a max "x" value of 47 and a max "y" value of 63, I'm pretty sure I haven't got the order mixed up, so I don't know why the program is segfault-ing? I'm sure it's some newbie mistake...

• binlog_format = STATEMENT and CURRENT_TIMESTAMP with MySQL replication

  - by xma

  Hi, can a MySQL slave instance have different row values for the same ID when binlog_format is set to STATEMENT and we insert something like: insert into foo values(CURRENT_TIMESTAMP) As I understand it, the slave read the SQL statement and execute it thus, if the replication is lagging, could lead to differences for the same row. Right or wrong ? How can I avoid this situation ? Thank you.

• Are Ruby formatted strings and interpolated strings identical in behaviour?

  - by Steve Weet

  Do the following two lines of code behave in exactly the same way despite slightly different implementations values.map{ |k,v| __send__('%s=' % k.to_s, v) } values.map{ |k,v| __send__("#{k.to_s}=", v) } The second line would be a more common ruby idiom so I was wondering why the other method was used when this was in the Rails Core which I would expect to use idiomatic ruby.

• C# WPF XAML Loading

  - by user3713589

  Hi I'd like to inquire on how i can load a WPF Xaml into code so that I can change the values of the attributes of some XAML elements and output it by creating another XAML files. This is so that I can output the same file with values dynamically input by the user. the XamlReader.Load() method cannot be used; it will throw an exception (because they are unable to recognise Window as the root element). I'm using VS2013 and C#.

• Why does this properly escaped SQL query fail?

  - by Jason Rhodes

  Here's the query: INSERT INTO jobemails (jobid, to, subject, message, headers, datesent) VALUES ('340', '[email protected]', 'We\'ve received your request for a photo shoot called \'another\'.', 'message', 'headers', '2010-04-22 15:55:06') The datatypes are all correct, it always fails at the subject, so it must be how I'm escaping the values, I assume. I'm sure one of you will see my idiot mistake right away. A little help?

• How do I generate an Array string from an array in memory (php).

  - by Itay Moav

  I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

• C++ pointer to different array

  - by begun

  Assume I have an array a and an array b. Both have the same type and size but different values. Now I create 3 or so pointers that point to different elements in a, you could say a[ 0 ], a[ 4 ] and a[ 13 ]. Now if I overwrite a with b via a=b - Where will the pointers point? Do the pointers still point to their original positions in a but the values they point to are now those of b?

• Problem using FormView to insert.

  - by matthew_360

  I have a formview control, and on the ItemCreated event, I am "priming" some of the fields with default values. However, when I try to use the formview to insert, before the ItemInserting event gets called, for some reason it calls ItemCreated first. That results in the fields being over-written with the default values right before the insert happens. How do I get it to not call the ItemCreated event before the ItemInserting event?
