I copied the following code segment from '.NET framework SDK Documentation' to get some details from the database. It works when I compiled it in the command prompt. But it doesn't when I execute the command Ctrl+F5 in Dev Environment; it generates the following error message.
===========================
C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705\Syste m.Data.dll Referenced class 'System.Data.OleDb.OleDbCommand' has base class or interface 'System.ComponentModel.Component' defined in an assembly that is not referenced. You must add a reference to assembly 'System'.
===========================
Help me!

Because i have NET 1.1 i say next

Assembly is module make in NET is DLL or EXE file

If use ctrl+f5 app run in other thread
If use f5 app run in thread Visual NET

in project you add referense to NET System*.dll (* - any symbol)
from Folder C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322
is folder default NET install (see folder)

but NET app in run is search System*.dll in GAC
folder by default is C:\WINDOWS\assembly\GAC
(gac - is global assembly (dll) cache - dll is used signed key)
to make key use command sn -k key.snk

To up speed load net app you need install all system*.dll
from C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322
to GAC use command gacutil /if system*.dll

if any quashion send to e-mail [email protected]

and Any Visual Component to NET to make any application by NET
