• Centering fonts in VB6

  - by James Musser

  How do you determine the length of a string of text in Arial Bold font, and then center it in VB6? If not here, can you point me in a direction where I might be able to find this information? We're not using a "label" or "picture box" do print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.

• Web Application Auditing

  - by Adonis L

  How can I audit a web application specifically database changes, when the application is connecting to the database as a system account?

I have read a few articles on identity flow but I do not fully understand the concept.

• How can I check for a file size and add that result in an Excel spreadsheet in Perl?

  - by Nano Taboada

  Currently I monitoring a particular file with a simple shell one-liner: filesize=$(ls -lah somefile | awk '{print $5}') I'm aware that Perl has some nice modules to deal with Excel files so the idea is to, let's say, run that check daily, perhaps with cron, and write the result on a spreadsheet for further statistical use.

  In Eclipse is it possible to create automatically Getters and Setters for a field. But I have a lot of private fields for which only getters should exist. Is somewhere in Eclipse a "create Getters" Function which does not create setters too? Well, it is not so much work to write getters, but doing it automatically would be nice :) Thank you, lerad

  - by zaidwaqi

• LDAP c++ API choice

  - by ypnos

  I would like to write my own LDAP client under Linux, specific to our local environment. Most probably I will use QT4 to provide a shiny frontend without much hassle. I found that there seems to be no standard C++ library for this. OpenLDAP provides a C API and there should also be a C++ API (experimental?) somewhere.. Do I need to use the C stuff or is there a C++ API out there worth of recommendation?
