Events in TDL

System Events - for Object Deletion and Cancellation

Event Framework has undergone significant changes during the recent past with the introduction
of System Events ‘System Start’, ‘System End’, ‘Load Company’, ‘Close Company’ and ‘Timer’.
In this Release, four new System Events viz., two Events for Object Deletion and two for Voucher
Cancellation, have been introduced. With the introduction of these Events, whenever an Object is
subject to Deletion or Cancellation, these events get triggered, which allows the TDL Programmer
to take some appropriate action. Only on confirmation of Deletion or Cancellation, these events
are triggered. In other words, only when the user confirms the deletion or cancellation of the
object by responding with a YES, the relevant events get triggered.

Irrespective of the Source of Deletion or Cancellation, i.e., from an external XML Request, Tally
User Interface, Remote Tally User Interface, etc., the appropriate events get triggered. Any Object
deletion or cancellation event gets triggered only at the Server end. Let us understand these
System Events in detail.

Delete Object Events – ‘Before Delete Object’ and ‘After Delete Object’

Two new System Events Before Delete Object and After Delete Object have been introduced in
this release. These events get triggered whenever any of the primary Objects defined in Tally
Schema is deleted. For example, Object Company, Voucher, Ledger, etc.
As the names suggest, the Events Before Delete Object and After Delete Object are triggered
before and after the deletion of the Object, respectively. The Current Object context would be
available in both these Events. Triggering of the Event After Delete Object confirms the successful
Deletion of the Object.

Syntax
[System : Events]
Label : Before Delete Object : Logical Condition Expr : Action Keyword : Action Parameters
Label : After Delete Object : Logical Condition Expr : Action Keyword : Action Parameters

Tally ODBC Driver Issue

Based on the Operating System bit (32/64) Tally has given the Exe. However the Micro Soft Excel application should be compatible to O/S and Tally.ERP9. Please note, On 64 Bit OS and 64Bit Tally.ERP9, a 32 Bit Excel application can act as a server with following steps. Please download from the Portal- ‘Microsoft Access Database Engine 2010 Redistributable’.  1. Install AccessDatabaseEngine_x64.exe Installed (steps given below separately.) 2. Excel 32 Bit (Excel 2003) Installed – and acting as server 3. Tally 64 Bit As Client –                      with ODBC Driver [ODBC: "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ=C:Tally.ERP 9 4.5 Build 7Sample Data.xls;"] and  Tally 32 Bit as Client – with ODBC Driver [ODBC : "Driver={Microsoft Excel Driver *.xls)};DBQ=Sample Data.xls"] This will resolve the problem by NOT upgrading MS Office to 64 bit. you can continue using 32 bit application of Excel.

LOG In function

During expression evaluation, intermediated values of the expression can be passed to calculator window and a log file ‘tdlfunc.log’ inside the application directory. This is very much helpful for debugging the expression. By default, logging is enabled inside the function. Syntax LOG : < Expression> Where, is the expression whose value needs to be passed to the calculator window. [Function : GetCurrentUserApprovelAmt] Parameter : PsvCurrentUser : String Variable : ApprovelAMT : Amount Return : Amount  10 : Walk Collection : ApprovelRequredColl  11 : If : $CustVAUser =  ##PsvCurrentUser  12 : Set : ApprovelAMT : $ApprovelAmount  12A : Log : ##ApprovelAMT  13 : End If  14 : End Walk  15 : Return : ##ApprovelAMT

Differences between Applications and DLLs

Differences between Applications and DLLs Even though DLLs and applications are both executable program modules, they differ in several ways. To the end user, the most obvious difference is that DLLs are not programs that can be directly executed. From the system's point of view, there are two fundamental differences between applications and DLLs: An application can have multiple instances of itself running in the system simultaneously, whereas a DLL can have only one instance. An application can own things such as a Stack, Global memory, File handles, and a message queue, but a DLL cannot.
