Hiding a Rich-Text field in Lotus Notes

Hiding a rich-text field. This is what my sis has been trying to achieve from past 2 hours now. Ah... it feels so irritating when you try to use all sorts of hide-when condition and it doesn't work. We tried normal field properties hide-when condition, tried sections, tried computed/computed for display etc. It did not hide.

Then I tried to google about it. It showed me several links with all stories in it. In the summary of a link I saw the name "subform". Eureka!!! I found it.

Automatically Moving Return Receipts to Folder

I wanted to move the Return Receipts that I receive to my mailbox, to be moved to the folder I created under Folders, named as "Return Receipts".

Tried some agents - did not work.

Tried rules that check for the Subject field containing "RECEIVED:" - did not work.

Then I forgot about it.

Few days back I again recollected of this task. I tried to check some unique fields or field values that differentiates the Return Receipts from the normal Memo.

I tried hard, could not find any unique field.

And suddenly my attention went to the Form field.

Yes, yes, yes. I found it.

Now, the job is to check if the Rules section takes care of the Form field or not. Or is it just for the Subject field only.

And I found it...

Now all my Return Receipts automatically go to the folder that I created, instead of remaining in Inbox.

Ways to do Version Controlling/Tracking

Version tracking is a feature that allows you to maintain the history of changes made in a document. And is another interview question.

Version tracking can be achieved in 2 ways. First through the Form properties and the Second is by using the reserved field $VersionOpt.

Replicate or copy documents and $KeepPrivate

a> How to stop users from creating local replicas or local copies?

b> How to stop users from copying / printing / forwarding any documents from the database?

c> How to stop users from copying / forwarding / printing an e-mail that you sent?

Authors vs Readers

Readers and Authors fields - a common interview question. I remember whatever interviews I have given in any organisation or who ever I have interviewed I have always asked them questions related to Readers and Authors field with lot of permutation and combination. Today I thought of documenting whatever I know about these fields, so I can refer to it whenevevr I want and brush up my brain a little if I have forget anything in future. 

Manager vs Designer

Manager

1. Can modify the database ACL.
2. Can encrypt the database.
3. Can modify replication settings.
4. Has the right to delete the database.
5. Can perform all tasks that are allowed to the lower accesses; i.e. Designer, Editor, Author, Reader, Depositor.

Designer

1. Can modify all the design elements in the database.
2. Can create a full-text search index in the database properties.
3. Can perform all the tasks that are allowed to the lower accesses; i.e. Editor, Author, Reader, Depositor.

Ways to Create Response Document

There are 3 ways to create a response document. Each way is in different language. In all the cases both documents remain in/must be in the same database. This is one of the interview question I was asked once.

1 > In Formula Language:
	a. @Command([ComposeWithReference]; server : database; form; flags)
		- form is the name of the form used to create the response document with and this form must have a rich text field with name as Body. - This command is called usually from a form action or view action. - So that it takes the reference of the currently open document or the selected document in the view. click here for more details.
2 > In Java:
	a. public void makeResponse(Document doc) throws NotesException i.e. responseDoc.makeResponse(parentDoc);
		click here for more details
3 > In LotusScript:
	a. Call responseDocument.MakeResponse( parentDocument )

Gradient effect in Lotus Notes Client and Web applications

Creating Gradient effect in Lotus Notes client is very easy. You just have to go to create a table in the form/page. Then in the Table Properties > in the Table/Cell Background tab you select Cell color. Then you select the type of style and choose the colors for the gradient. And your table cells are ready with the gradient effect.

However, this gradient effect is not visible in web. Thus, you have to find some other way to color the cells with gradient effect.

Problem Scenario:

You have recently deployed some of your changes and suddenly every document gets locked. You can’t edit any existing documents or save a new document. When you close or open any document you get the following error:

You can’t do anything with the database. You check in your test copy and everything works perfectly fine there. You check the production copy’s data size and it is not too much to trigger the error. This error doesn’t let anyone to make any changes to the database.
