Generate and Validate Captcha Code

Suppose you have developed your own web app with InterSystems technologies stack and now want to perform a captcha validation on the client side in order to determine whether or not the user is human and make it safer. There are some modern frameworks to address the captcha issue, however most part of them needs internet access to generate codes and sometimes are complex to implement. Take this as basic example considering that image recognition has gotten too good. That's why you nowadays you tend to see more pattern recognition captchas than mere reading ones. (I.e.

Hi all

I have a Zen page which displays the contents of a table. One of the columns is a file path to a file on a local disk.

Is it possible, on a Zen page, to allow that file that described by the file path to be downloaded when a hyperlink is clicked on?

Cheers

link component on a ZEN page

When using the link component on a ZEN page the default behavior is for the link to appear to the right of the tablepane row. Has anybody changed this behavior so the link appears to the left of the tablepane row? Thank you in advance for any and all feedback.

I have a PDF ZEN report module that I'm using XslFoXslt to highlight the table cell.

What I need is for a particular value to add a background image to the <item> that is calling the XSLFoXslt

The code I have is the following but all that happens is the color.

Hi All,

I'm having a strange issue where doing a .setValue on a ZEN datacombo is updating it with the value as-is, not the corresponding display value. Eg, if I connected it to query that returns two columns: ID,Name, and do a setValue(ID), I would expect the text in the datacombo to update showing Name. Instead it updates show ID, which I only want to use internally.

When refreshing a html or tablePane component using refreshContents() that takes a lot of server-side-processing, I'm running into timeouts every now and then. i.e., the result for the tablePane is that there's nothing displayed at all.

How can we configure (relax) that timeout so also those heavier ones get refreshed eventually? Just overriding %request.Timeout in %OnPreHTTP did not seem to do the trick.

AWS SSO Login

Hello,

We are using AWS SSO authentication in our application to validate the users. For validating the users, we are passing the username and password from AWS SSO to our application. We need to validate the user in our application without using the password.

We developed the login class using zenPage. We used <loginForm> tag in the login page which is used for the automatic validation.
Is there any possible way to achieve this?

Thanks in advance.

I'm using FOP 1.1 for ZEN reports and would like to install fonts within the Windows/Fonts directory.

I added the xml tags in fop.xconf but so far I have been unable to get the correct font.

<renderers>
<renderer mime="application/pdf">

<fonts>
<directory>c:\windows\fonts</directory>
<!-- automatically detect operating system installed fonts -->
<auto-detect/>
</fonts>

</renderer>

</renderers>

Any advice would be appreciated.

There is a finite list of date formats that users want to use to enter a date in a form. These formats include single digits for month and day and double digits for year. The field is represented by a dateText control.

How would one get to allow a dateText control to accept multiple date formats ? I see only 3 listed here, do those include using single digits for month and day ?

Hi Community,

is there a possibility to implement a "remember password" feature in a ZEN Application?

In the management portal I added a web-application for a ZEN application with password authentification. I created an own login page, and now I want to implement a "remember password" feature (User should not have to login again after the session times out or when the browser window is closed).
