C# and ADO NET - doesn't work.

[Dmitri Shvetsov]

Hi,

What could be a reason? I wrote a Windows Application on C#. It works with a
remote database through the Internet. It works excellent on my developer's
machine. When the application is moved to another machine without VS2003
installed it starts ok, but can't download a DataSet from the remote
database and I don't see any data. No any errors are shown, nothing that
could be helpful.

It looks like that the VS installer doesn't add some required libraries and
it can be a possible reason of this fault. But why? I created a new "Setup
and Deployment Project", started a wizard, created everything that was need.
The MSI/Setup.ini+exe were created. But finally after this installation the
application doesn't work with the remote database.

Hi,

Microsoft Data Access Components (MDAC) SDK (Ver 2.7)(3790.0).

Should I delete it and install again from the
http://windowsupdate.microsoft.com?

Hi,

Does somebody know what's a problem? When I try to create a deployment
package using a standard project in VS2003 the VS barks that: "Error 1706.No
valid source code could be found for product Visual Studio .NET Enterprise
Developer 2003 - English. The Windows installer cannot continue."

I click OK and the creation continues. Then again and finally one more time.
Totally 3 times. Finally the VS reports that everything was excellent, no
errors, no warnings, and the setup package is created.

---------------------- Done ----------------------

Build: 2 succeeded, 0 failed, 0 skipped
That's the picture.

Hi,

Thanks for your hint!-) That's what I found last night.

http://msdn.microsoft.com/library/de...components.asp

Any Visual Basic or Visual C# application that includes data access has a
dependency on Microsoft Data Access Components (MDAC) version 2.7 or later.
MDAC must be installed on a target computer prior to installing your
application or the application will fail.

Thanks, Bill! That's very cool deployment!
