Chapter 1. Getting Started
AspGrid 3.1 requires:
Windows 2003, Vista, 2008, 7, 2012, 8, or
Windows 2000 Server/Advanced Server and IIS 5.0, or
Windows 2000 Professional and Personal Web Server, or
Windows NT 4.0 Server SP5+, IIS 4.0, and MDAC 2.5, or
Windows NT 4.0 Workstation, Personal Web Server, and MDAC 2.5,or
Windows 95/98, Personal Web Server, and MDAC 2.5
To install AspGrid, download and run the setup
application aspgrid.exe . The aspgrid.exe
setup will install both the AspGrid component (aspgrid.dll) and
all the documentation into a directory on your hard drive that
you specify during installation.
Typically, it is c:\Program Files\Persits Software\AspGrid,
but it can be any other directory. The install routine will
automatically register the component DLL on your machine.
During installation, your IIS-related services will be shut down
Installing aspgrid.dll under MTS/Component Services
If you need to move the AspGrid component to another server,
it is sufficient to copy the file aspgrid.dll (located under the \Bin subdirectory
of the installation) to the other machine and register it there using
the regsvr32 command-line utility. You may copy the file aspgrid.dll
to any folder on the second server's hard drive, e.g. c:\winnt\system32. To register the dll,
run the MS DOS prompt and type the command
You must specify another path if necessary. If this server is already
running an older version of AspGrid, you must remove it from memory
prior to registering a newer version by shutting down all IIS services.
To do that, type the following command at your DOS prompt:
net stop iisadmin /y
To bring the WWW service back up, type the command
net start w3svc
Other IIS services can be restarted from the Services control panel.
AspGrid can be used in Microsoft Transaction Server (Windows NT 4.0) or
Component Services (Windows 2000).
"/AspGrid" Virtual Directory
Under NT 4.0, run Microsoft Management Console (MMC) found in
the Option Pack 4 program group. Under Windows 2000, run Component Services
found under Control Panels/Administrative Tools.
In MMC, open Microsoft Transaction Server and
expand the branch Computers\My Computer\Packages Installed. Create a new package.
In Component Services, expand the branch Computers\My Computer\COM+ Applications. Create a new
Once a package (application) has been created, use File Explorer
to drag the file aspgrid.dll and drop it onto the Components sub-folder of the new package.
See Chapter 12 to learn how to configure AspGrid to take advantage
of MTS/COM+ Role-based security.
The AspGrid.exe setup routine attempts to add the virtual directory
/AspGrid to your web server. This virtual directory is created on top
of the \Samples sub-directory of the installation and
points to code samples shipped with the component.
Using Microsoft Management Console (or Internet Services Manager in W2K) make sure this virtual directory
has been created, and if necessary, re-create it manually. To test it,
run the following URL: http://localhost/aspgrid/01_start/justatest.asp.
Sample Microsoft Access Database
The AspGrid installation comes with the file AspGrid.mdb
located in the directory \Samples\DB
a collection of tables that all the samples in this manual use.
The database file is in the MS Access 2000 format. If you are using
an older version of MS Access you will have to re-create this
The AspGrid.mdb database contains three tables: departments,
employees, and cities The first two tables
are connected via a one-to-many relationship: each
employee is assigned to exactly one department, and each
department has many employees. The cities table
is stand-alone and is only used by the last chapter of the manual.
The database tables, their fields and relationships are shown on the following
Each table in the sample database has the field id of the type
Autonumber. An Autonumber field is filled with a unique value
automatically by the database management system every time a new record is added to the table.
SQL Server calls such fields IDENTITY columns.
For a grid to be editable, a table it is based on must have an Autonumber (IDENTITY) column.
This important requirement will be covered in detail in the next chapter.
You may choose to run all the code samples from this manual
against a SQL Server database instead of Access. To simplify
the process of re-creating the sample database structure in SQL Server,
we have provided the SQL script file sql_server.sql which can be found in the
\Samples\db\ sub-directory of the installation.
You can run this script using SQL Server Query Analyzer.
The Oracle database management system does not provide an equivalent of the MS Access Autonumber or SQL Server IDENTITY
column. It is still possible to use AspGrid against an Oracle table
that implements automatic unique numbering for one of its columns.
This can be achieved using Oracle's SEQUENCE's and TRIGGER's.
We have provided the SQL script file oracle.sql which
re-creates the sample database structure in Oracle.
This script not only creates the three sample tables, but also
emulates IDENTITY columns for the Employees and Departments tables via two SEQUENCE's and
The file oracle.sql can be found in the
\Samples\db\ sub-directory of the installation. The simplest way
to run this script is via Oracle's command-line utility sqlplus. At the DOS prompt, type
After logging in, type at the SQL> prompt:
