This posting will describe how to change your default system browser on Windows XP to a portable version of Mozilla Firefox using a free program called DefaultBrowser, doing so reversibly and without installing the non portable version. The same process described here could be used to change your default browser to any portable (or non portable) browser.

This posting will describe how to split a very large CSV or Text file into a number of smaller parts by specifying the number of desired lines within each of the resulting pieces (for example, by 65536 lines for use with Excel 2003 or 1,048,576 for Excel 2007). The method described will use free software to do this and will work for very large files (even files larger that 4 gigs in size), will avoid loading the entire file into memory when processing, will maintain the format/extension of the original file, and will not add any additional information to the resulting files.

If you’ve ever encountered a blocked startup app in Vista and would like a work-around that can bypass it then read on. This posting will describe how to launch an app on startup as a scheduled task, which will circumvent the startup apps list altogether. Ultimately you will be able to get your app to launch without seeing the notice in the screenshot and without having to shut down Vista’s User Account Control security infrastructure.
