Building strawberry perl with modules
I want to use perl at work to automate some tasks. This is a windows environment. Strawberry perl is available via the 'software center', BUT the usual way of using cpan to install modules is blocked, as is dmake. IT and security are open to bulding themselves an installable (e.g. msi) with the... -
weird storage behaviotr leading to segfault
I need to pass a set of arrays to a program that does the work (e.g. an ODe solver). Now the way this is written is it allows a parameter array RPAR which is a 1-d double precision array However, the parameters that must be passed are a number of multidimensional arrays, and in once case a... -

When running the zgees lapack program the actual matrix dimension N (=4) apparently changes to 0 on a statement SDIM=0 that does not affect N I looked for a NaN problem, but could not find something Then I ran gdb and noticed that although the declared matrix dimension LDA=10, these arrays... -

Regular expression question
Can one use str_replace to do this: $string=' AND VALUE=..... AND .....'; should end up removing the leading AND In perl this would be $string=~s/^\s+AND// or$string=~s/^AND// (yes, it can be do in one statement) to remove a leading 'AND' and possibly any whitespaces(blancs) before it. -
odbc connect and check issue
I'm apparently having some trouble with an odbc connection. I deliberately to debug put the connect script in the main, but still no luck. odbc sees a true $link, but thinks it's not a 'resource'. <?php ini_set('display_errors', true); error_reporting(E_ALL); if(session_id() == '')... -
Local vs remote database
Just about to move from a local to a remote database. Is there anything else I should worry about except for : a) specifying the database e.g. $link = new mysqli('localhost', $dbusername, $dbpasswd, $db); changed to $link = new mysqli('http://www.mybdsite.org/database_path/', $dbusername... -

I'm looking for any tips for easy passing of values from a static page to a php page which will do queries.

I'm looking for recommendation on how to: -install Apache on Windows -install PHP on Windows -connect to an Access Database For Apache and PHP it looks like one may need a C compiler (or probably specifically MS Visual C?) Is that correct or can one also find a binary or an installer? Also in... -

Consider a set of possible combinations with order important, e.g. (1,7,8,-1,6,3,5) (2,6,1,4,7,-1,5) ...... The problem is: First, create(that's not the issue here) and store such a combination in an appropriate datastructure Second, when later on one generates a nw combination, search... -
calling a non-php program?
Just wondering if it is possible for pHP to call an external program. For instance perl can do system("myexecutable.e"); The idea is that the script may want to take a decisions based on more intricate processing than what a database can do. I've never seen this though, so I'm not sure it's... -
Baloon with PHP code?
I wonder if it is possible to display baloon widgets with PHP/html? The idea is that following a database query, a table is displayed. Table entries have further information that is too detailed to display, hence it might be a good idea to have a ballon pop up when the mouse hovers over that... -
