Convenient way to add new records by copying its parameters from template

I think it would be very convenient if we could use Data Templates when creating new record.
This way users shouldn't do fool mistakes on filling some mandatory fields like posting groups, location codes etc.

Let's take for example Item table.

There are several issues why we can't use Form - OnNewRecord and Form - OnInsertRecord triggers. In the first case we can't insert new record, because the transaction could not be started there. In the second case 2 records would be created, 1st record is copied from template and 2nd is inserted with empty fields in a standard way.

That's why I've created new menubutton with F3 shortcut on Customer Card. This button should intercept event of creating item (pressing F3 key). The code of trigger is below:

Incremental SSIS package template

Some time ago I was engaged in building Data Warehouse (DWH) for NAV database. To develop incremental data transfer I used system field timestamp, which is present in every NAV table. I build the table, called Timestamp Settings in DWH with the following structure:

Where CompanyID is the index of NAV company in DWH.
When the SSIS package launches, the script task, which reades the last timestamp values, is fired.

Using web-service to send SMS from NAV

Recently I had a task to send SMS notification through the Webservice.
My service provider use following interface protocols.
Request for sending SMS:

Where:

• login and password are the authentication parameters;
• id is the internal message ID;
• recipient is the mobile phone number of the recipient;
• sender is a sender description;
• text is a message text.

This request should be posted to a webservice via HTTP or HTTPS.

Item lookup with built-in search

Let's take a look at the operations, that manager executes every time he adds new item to an order:
1. Pushes lookup in the No. field
2. Goes to a Description field and starts to write an item name.
3. Chooses a necessary item.
If a user knows an Item name, then he can write it directly in No. field. NAV will search for an Item, that begins with an entered phrase and insert it's code to a No. field. It is because of AltSearchField property, setted for the Item table.
But what if several items, which Description field contains entered phrase exists? NAV will find only first of them... It's not convinient and that's why users prefer searching items in the item list, spending more time for every line.

My suggestion is to let the user choose an item from a list, if there are several items, that complies his request. It's a kind like incadea does...

Subform detail or summary view

Often there is so many fields on a subform, that user become confused. It's a standard Navision way, that user can customize those fields, that he wants to view on the subform. But, I think, more user-friendly is to have a button, that switches from summary view to details if user wants to enter extra-data.
Lets take for example Sales Order. I've created 2 buttons, place them on each other below the subform: bSum & bDetails.
bSum is not Visible by default (property Visible = No), it means the Summary view will be shown by default and user can switch to Details.

Using LumiSoft.Net for retrieving e-mail from Dynamics NAV

Recently, I've found great library for net handling (POP, SMTP, FTP, HTTP and others) - LumiSoft.Net http://www.lumisoft.ee/lsWWW/download/downloads/Net/LumiSoft.Net.zip

Here is the link to the help index for that library http://www.lumisoft.ee/lswww/download/downloads/Net/Help/. Exciting!
It's open source (C# .NET) and completly free for modifing and using in commercial projects. Wonderfull, many thanks to it's author!
So, I was engaged in using this library in Dynamics NAV.

First of all, this library should be compiled as COM Automation object. For this possibility:
1) COM Interop on the project tab should be checked.
2) Special attributes for COM sharing should be appointed for the classes:
[ComVisible(true), ClassInterface(ClassInterfaceType.AutoDual),Guid(" ... ")]
Namespace System.Runtime.InteropServices should be used.
3) GUID for assembly should be appointed:
[assembly: Guid(" ... ")]
4) some classes should be redesigned (for example, static members are not visible in COM)

If Guids are not appointed that way, the linker automatically creates it, but every time you making changes in the source code you would have new Guids. It's too difficult for parallel NAV debugging, because C\AL variables are droped after new COM server is registered. The description "Unknown Automation Server.Unknown Class" is shown in that case.
I used special tool for Guid creation (Tools - Create Guid in Visual Studio).

In Dynamics NAV I've created a pair of simple tables (Message and Mailbox). Message have a table relation to Mailbox:

Simple way to store password in database

Imagine, you want to store user password to access external NAV portal, and no one must see it.
You can, of course, set the property to PasswordText  = Yes on the form. But, what if the user press Ctrl + F8 to view fields inside the table? ...
So, let's write a little function to store protected password text.

Password - OnValidate()
Password := EncodeDecode(Password);



EncodeDecode(String : Text[30]) : Text[30]
FOR i := 1 TO STRLEN(String) DO
BEGIN
  Ch := String[i];
  Pass[i] := 255-Ch;
END;
EXIT(Pass);

So, you can use this function not only for encoding text, but also for decoding.
