A recent need to download all the images stored as BLOB (Binary Large OBject) from a database lead me back to ColdFusion. Using the toBase64() and imageReadBase64() functions along with the cfimage tag I was able to create a page that displays the images in the database and writes them to a file on the server.
I have used the official ColdFusion since 1997 when it was owned by the Allaire brothers. I used it when Macromedia owned it. I used it when Adobe owned it. I have also used Open Blue Dragon and now I have used Railo. Given the price comparison, Railo is so far my favorite flavor of ColdFusion. Here’s a few reasons why and a small datasource IsItUp script.
What you need to do: print something to a Windows printer from your ColdFusion application on Linux. How to do it: use the samba tool suite to execute a print command, sending a file to a printer. I use a small form to collect the data that I need to print. The form results are written to a file and then the file is sent to the printer using cfexecute. <cfexecute name=”/usr/bin/smbclient” arguments=” //print_server_ip/virtual_printer_folder my_password […]
I’m in the final stages of adding support for H2 databases to the OracleAED project hosted on RiaForge. This is really quite exciting to me because the project is growing beyond support for Oracle databases. The H2 database is also exciting in it’s own right. I’ve found it to be easy to use and rich with features that young database engines just don’t have like drop column and the data dictionary (INFORMATION_SCHEMA) made adding H2 […]
I just need to take a minute or two and speak favorably of a handful of software. VirtualBox – makes it insanely easy to run an OS inside an OS. Fedora 15 – feel the love. OpenBD – Open source. Cold Fusion. Linux. H2 – it’s supported in OpenBD and the more I use it the more I like it.
