"Object reference not set to an instance of an object"

Kam
Hi!

When I am trying to drag user controls or any controls from the Toolbox to a
form in some of my projects I get a dialog messages: (Microsoft Deployment
Environment)
"Object reference not set to an instance of an object"

Notes that:
1. It's a designer problem, not a reference problem. When I am adding this
user control directly to the code it works just fine, but I can't make it
work using the designer and see it in design time.
2. It happens only in some of the projects in the solution, not all of them.
3. In my company we are working with 'Microsoft visual source safe' and
other members of the team don't suffer
from the this problem.
4. Getting the latest version from 'source safe' didn't help.
5. Reinstalling VisualStudio .Net from scratch didn't help
6. When I am logging in as a different user the problem remains.

How can I restore the functionality of the designer to work with
(is it an environment problem)?

many thanks,
Kam

when you say user controls if you mean custom built ones
and not ones that come with visual studio then...

remember that code actually runs at design time.

for example, when you drop a user control onto a form the
constructor code will be run.

if your machine is missing support libraries for the
offending control then these problems are bound to happen

A three-tier user authentication system was running without a problem for almost a year and now is suddenly dysfunctional. We don't know of any changes to any of the servers. It's quite maddening.

The component graphic spins when CreateObject is called. 2) The proxy is installed on an IIS server (Win 2000) with delivers the interface, written in ASP, to the...

I suddenly received an unexpected error in my project. I have been working on this project for some time without this issue. Nothing has changed in the form that caused the exception. A little experimentation shows that I cannot run ANY .NET web project without getting this error: ---------------------------------------------------------------------------- ---- Object reference not set to an instance of an object.

This JUST started happening, I don't remember changing any code: When I click the submit button on my form, stuff is supposed to happen (which it does correctly) and a result message is posted back to the same page at the top of my form alerting the user that their request has been approved or denied. However, the end result is an error message: Error Message: Object reference not set to an instance of an object.

Ok guys, I'm really looking for someone to tell me how bad a hack this is, and if I'm close to where I should be with it. The basic situation is that I have a class which creates a basic calendar control, the only difference is I stole the navigation scheme from Vista (e.g., if you click on the year you zoom out to the months list, then out to the decade, and back in when you click a year, then a month). I ran into some trouble...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
