Although I have been in the technology field for ~10 years, I am rather new to blogging, and am quite frustrated with how difficult is seems to be to post an entry which has a bunch of images in it. This is especially true when you are writing up a how to with screen shots and the like. I don’t want to FTP all the images up and then hard code references to them in my blog entry. That is painful, and we’ve come to far to be doing anything manually.

So what I do is the following, and uses a combination of BlogJet and Evernote.

Both have greate features, but like anything else in this world, unless google wrote it, you need 2 tools to do the job of one….so that’s what I do. Using this method streamlines image uploads in your blog and make the task of blogging absolutly painless…

*I invite you to please comment and let myself and others know a better way or the way you do handle your blogging.

HERE GOES….

First you must create the Note in Evernote. One of the many, many, many beauties of Evernote, is it allows to copy images, directly from the clipboard. So that when I am writing a tutorial, I can just paste everything directly into Evernote. Once your note is created….

Here are step by step instructions.

“PDF Split and Merge is an easy to use tool to merge and split pdf documents. Console and GUI versions are available. The GUI is written in Java Swing and it provides functions to select files and set options. It’s made over the iText library.”

You will need the Java Run Time environment installed on your PC. You may already have it it, but if not its a free download over at java.com

Hold CTRL and Left Click the Mouse to select multiple (that’s for my mom)

Need to export a Flex Datagrid to Excel CSV?

Here is a link to the Flex code

The flex code will convert the DataGrid to a CSV string. Which you will then post to a cgi….code below.

You can see it in action on my Dividend Reinvestment Tool 

#!/usr/bin/perl
use CGI qw(:standard);
my $cgi = new CGI;
my $count = 0;
use CGI::Carp qw(fatalsToBrowser);
$title=$cgi->param('title');
$html=$cgi->param('htmltable');
$type = $cgi->param('type');
if ($type = "CSV") {
print $cgi->header(-expires=>'now', -type=>'application/x-csv', -content_disposition=>"attachment; filename=$title.csv");
print "$html";
}
else {
print $cgi->header(-expires=>'now', -type=>'application/octet_stream', -content_disposition=>"attachment; filename=$title.xls");
print $cgi->start_html(-title => 'Export'
);
print "$html";
print $cgi->end_html;
