Cloning your Corporate UI with HTML DB - Part IV (Re-Post)

The following is a re-post of the "Cloning your Corporate UI with HTML DB" series that I blogged about back in 2005 on the now-defunct Orablogs site. Most of the content and advise is still the same today, and has been reposted here exactly as it was on the old site.

June 14, 2005
In the last installment, the converted site looked pretty good, but the tabs were not quite working. The issue here was overlapping FORMs. If you look at the HTML source of the OTN Home Page, there's an HTML Form which processes the "Search" function. This form was overlapping with HTML DB's Form; thus generating an error when a tab was clicked - which essentially does an HTML POST via a JavaScript function.

In HTML DB Templates, two commonly used tokens are #FORM_OPEN# and #FORM_CLOSE#. These tokens are used where you want to open & close the "functioning" portion of an HTML DB Page. When an HTML DB page is rendered, the #FORM_OPEN# & #FORM_CLOSE# tags are substituted with some dynamic values, as outlined below:

#FORM_OPEN#
<form action = "wwv_flow.accept" method = "post" name = "wwv_flow" id = "wwvFlowForm">
<input type = "hidden" name = "p_flow_id" value = "20530" id = "pFlowId" />
<input type = "hidden" name = "p_flow_step_id" value = "2" id = "pFlowStepId" />
<input type = "hidden" name = "p_instance" value = "2734685902684999721" id = "pInstance" />
<input type = "hidden" name = "p_page_submission_id" value = "21133974" id = "pPageSubmissionId" />
<input type = "hidden" name = "p_request" value = "" id = "pRequest" /> </ table>

#FORM_CLOSE#
<input type = "hidden" name = "p_md5_checksum" value = "" />
</form>

The real beauty of these two tags is that you don't need to know what any of the above HTML really does. It's simply enough to include them in your HTML DB templates, and they will just work. That is, of course, if you don't have overlapping FORM tags...

Back to our page in question. By moving the #FORM_OPEN# token to after the HTML which closes the FORM for the Search box, the page will now work. This presents a bit of a design challenge now. In the current version of HTML DB Studio, there is a Search field which only searches content in HTML DB Studio, not the rest of OTN. I'll have to think about whether I want to have a) two search boxes b) an OTN Only search box c) an HTML DB Studio Only search box or d) no search boxes. Technically, any of these four options are possible. It's just a matter of design choice.

That's all for now - sorry that this has been the shortest entry, but I've been taking a class all week, and evenings have been spent catching up on e-mails, etc. Add to the mix that my wife sprained her ankle today and is not supposed to walk on it, and I am all of a sudden quite busy tonight!

Whose Deck is it Anyways?

This year at KScope, we're going to try something new.  And fun.  And funny to watch - we hope.  It's called "Whose Deck is it Anyways?", and will occur on Sunday at 8:30pm.  It's only 30 minutes, but it will likely be the best 30 minutes of the conference.  Or at least the most embarrassing.

Here's what we're going to do: the will be four 5-minute presentations - one on each of the following: BI, EPM, Database & APEX.

Sound interesting?  Probably not.  We get that, too.  So here's what we did.

Each 5-minute session will be presented by a non-expert.  For example, it's highly likely that I'll be presenting on BI or EPM.

To make it even better, each slide deck will be prepared by the corresponding expert.  So again, it's highly likely that my slide deck's creator will be either Stewart Bryson or Edward Roske.  If nothing else, this session will be a crash course in how not to make cohesive, easy to read slides.

Interested now?  Ya,…

Spaced Out

A while back, I wrote about how to give the Universal Theme a face lift.  If you follow the steps in that post, the base font for an APEX application with the Universal Theme can easily be changed.

While that's all well and good, sometimes you only want to change the font for a report, not the entire page.  One of the applications that I'm building contains a number of IRs based mostly on log data.  Thus, having that data in a monospaced font would make it a whole lot easier to read.

You can search Google Fonts for monospaced fonts by selecting only that option on the right-side menubar.  You can also opt for the standard yet kinda boring Courier and achieve the same thing.

To implement this in your application, follow the steps in my other post, but stop shy of the final step.  Instead of pasting in the text that I specify, paste in the following to the Custom CSS field in Theme Roller, using the name of the font you selected for the font-family:

.a-IRR-table tr td { font-fam…

#fakecode

Unless you've managed to somehow filter out everything about US politics over the last few months (and if you have, please let me know your secret), then you've likely heard about "fake news".  From a high level, my basic understanding of "fake news" is that it refers to stories or websites that are fabricated to advance the political beliefs and/or ideologies of one site or the other.  Your definition may differ.

So what is fake code?  That, I can at least try to explain in a bit more detail.

The other day, I saw this image posted on Kris Rice's twitter feed:



I thought it was a joke, but it's actually a real book. That made me laugh.  Then cry.  Then I read the book, mainly since it's only 4 pages.  Believe it or not,  there's actually some really good content packed in there.  Let me summarize:

If you choose to copy code from Stack Overflow, the OTN forum, or anywhere, really, there's a few things to keep in mind:


Who owns the code.  It…
