Services Barcode Tutorial
This SSRS Barcode Tutorial provides step-by-step instructions for adding
barcode generation technology to Microsoft SQL Server 2000 Reporting Services
and Visual Studio 2003 environments. This can be accomplished by using
IDAutomation barcode fonts in conjunction with the .NET Report Function Custom
Assembly file, a font encoder that is free to use with IDAutomation demo or
purchased products. When using Reporting Services 2005 or 2008,
IDAutomation recommends using the
Reporting Services Barcode CRI component to create barcodes on reports.

Reporting Services Barcode Tutorial Overview
The .NET Report Function Custom Assembly file used in this tutorial formats the data-to-encode specifically for use with IDAutomation's
barcode fonts, and is designed to meet the specifications of the symbology laid
out by the AIM and/or ANSI standards. This example will demonstrate how to build a report based
on the "Customers" table of the Northwind database. The report will
include the database fields of CompanyName,
CompanyID, and ContactName.
A custom field will be added to the report, which will provide a Code
128 barcode representation of the Company ID.
To use this tutorial, the following requirements must to be met:
- Visual Studio .NET 2003 should be installed.
- Access will be needed to a SQL Server 2000 SP 3a database. This
tutorial will make use of the Northwind database that is included with the SQL
- Reporting Services must be installed.
- The .NET barcode custom assembly,
IDAutomation.com.FontReportFunctions.dll, should be

barcode fonts used in this tutorial, which encode numbers, upper and lower
case letters, special symbols and functions.
Download IDAutomation's Microsoft Reporting Services Custom Assembly
and unzip the file to an easy-to-remember location. The IDAutomation.com.FontReportFunctions.dll
assembly will be
in the zip file.
Copy the custom assembly DLL to the Report Designer
folder. The default location of the Report Designer is C:\Program Files\Microsoft SQL Server\80\Tools\Report
The assembly also needs to be copied to the Report Server
directory so that it is available for deployment. The default location
of that directory is
C:\Program Files\Microsoft SQL Server\MSSQL\Reporting

Barcode Function List
For all Reporting Services barcode functions below, the data input type is a single string.
For all number symbologies, such as Postnet and UPC, dashes or spaces
may be entered for greater readability, but will be filtered out by
the function before the barcode is generated. For UPC-A, UPC-E & EAN-13,
the +2 and +5 add-on barcodes may be created by appending them to the
end of the string.
||Function Notes and
||This is a "Code 128 Auto" function that
will automatically encode any data from ASCII 0 to ASCII
127, and will automatically switch to character set C for numbers.
Code 128 barcode fonts have many options:
Encoding: to encode alpha-numeric
UCC/EAN128, the character set must be "0" or "AUTO" for
automatic (the default setting). ASCII 202 or character
Ê is recognized as the FNC1 before each AI. When a barcode
begins with an AI, the required start C is included automatically.
For example, the UCC number of (8100)712345(21)12WH5678
should be entered as: Ê8100712345Ê2112WH5678.
In most cases, the AIs will be properly represented in the
human readable text. If the parenthesis is not around the
correct number for the AI, enter the following extended
ASCII character as the FNC1 for the correct number of digits
in the user's AI:
ASCII 212 = 2 digits ASCII 213 = 3 digits
ASCII 214 = 4 digits ASCII 215 = 5 digits
ASCII 216 = 6 digits ASCII 217 = 7 digits
For example, to encode (1277)56, enter Ö127756.
Apply Tilde: when using
Code 128, the character set is Auto and ApplyTilde is True,
the following options are available:
- Encode ASCII Characters:
The format ~ddd may be used to specify the ASCII code
of the character being encoded. For example, if the
128~029TEST in the data field, the user will be encoding
is a delimiter ASCII 29 character. Other commonly used
ASCII codes are ~032 the space, ~202 the FNC1, ~197
the FNC2, ~009 the tab and ~013 which is a return function.
For encoding other functions, please refer to the
- Create a Mod-10 Check-Digit:
To create a Mod-10 check-digit
for xx number of characters, add the following to the
DataToEncode: ~mnn (where nn is a 2 digit number representing
the number of characters preceding the tilde in which
to base the Mod 10 calculation). The additional MOD-10 check digit is commonly used in UCC or EAN barcode
types. For example, setting the DataToEncode property
to Ê4021234567890123456~m16 will create a mod-10 check-digit based on all 16 characters before
the tilde. The human-readable text and scanned data
will display as (402)12345678901234566. The final 6
is the mod-10 check-digit and replaces ~m16.

A number string. A MOD 10 check digit
is returned. This is useful in calculating check digits
for UCC/EAN 128 barcodes where a MOD check digit is needed.
||Data is a number
string of 7 or 8 characters (EAN-8 without the check digit).
Formats output to the UPC/EAN barcode font. Entering incorrect
data will create a barcode containing all zeros.
Using the ApplyTilde Character
This Code 128 function allows for the encoding of unprintable ASCII
characters and calculation of a Mod 10 check character by denoting the
tilde character (~) as a special processing delimiter. When the
parameter is set to true, the function assumes that special processing
will occur, and thus does not encode the tilde character. When encoding a tilde character in the
Code 128 barcode font, set the ApplyTilde
property to false.
- Encode an ASCII Character: The format ~ddd may be used
to specify the ASCII code of the character to be encoded. For example,
if entering 66~02977 in the Data field,
66GS77 will be encoded
where GS is a delimiter ASCII
29 character. Other commonly-used ASCII codes are ~009 for a tab
and ~013 for a return function. Please refer to
ASCII chart when
encoding other functions.
- Create a Mod 10 Check Digit: To create a Mod 10 check
digit for xx number of characters, add the following to the
~mnn where nn is a 2-digit number representing the number
of characters preceding the tilde in which to base the Mod 10 calculation.
The additional MOD 10 check digit is commonly used in UCC or EAN
For example, setting the DataToEncode property to
Ê4021234567890123456~m16 will create a mod 10 check digit
based on all 16 characters before the tilde. The human-readable
text and scanned data will display as (402)12345678901234566. The
final 6 is the mod 10 check digit and replaces ~m16.
Additional Code 128 Auto Function Features
- Manual Setting of the Number of AI Characters:
In most cases, the Application Identifiers will be represented properly in the human-readable text. If the parenthesis is not around the correct number
for the AI, enter the following extended ASCII character as the
FNC1 for the correct number of digits in the AI:
ASCII 212 = 2 digits
ASCII 213 = 3 digits
ASCII 214 = 4 digits
ASCII 215 = 5 digits
ASCII 216 = 6 digits
ASCII 217 = 7 digits
For example, to encode (1277)56, enter
- FNC2: The FNC2 character may be inserted
into the DataToEncode string by using ASCII 197. For example,
Å8012349091. The IDAutomation
Barcode Scanner may be programmed to hold the barcode starting with
the FNC2 in memory, and only transmit it to the computer after scanning
a barcode containing the FNC1.
