In VS2005, VB 2005, I suddenly can't get at a winform design view. The
application still runs OK, but I can't see the designer.
I'ver rebuilt the solution with no success.
I'm looking for a general strategy for dealing with this problem.
Here is the error text:
Object reference not set to an instance of an object.

Hi,
I wanted to insert linebreaks in the tooltip property of some of my
controls.
I simply altered the designer generated code in InitializeComponent:
Me.MyTooltip.SetToolTip(Me.TextBox1, "Text line 1" & vbCr & "Text line 2.")
But whenever I change back to desinger I get this error in the Task List:
"The variable 'vbCr' is either undeclared or was never assigned."

Hi,
When I open a large solution in VS2003. I get over 2000 errors in my task
list. The text "Empty" afters in the Class and Member dropdowns. If I close
I get the Microsoft Error dialog, and VS2003 reloads.
Any thoughts

here is an error I get when I open my class library project:
"The class ResultsTable can be designed, but is not the first class in
the file. Visual Studio requires that designers use the first class in
the file. Move the class code so that it is the first class in the
file and try loading the designer again."
What does that mean, "the class xxx can be designed"?
thanks,

Hello,
>From time to time my vb2005 form disappears and is replaced by the
following errors. Rebuilding the application never helps. However the
errors never affects the operation of my application that I notice, but
it is very anoying.
To get rid of the errors I must close the form, close the application
and then reopen it.

This BUG that is so ridiculous I can't believe they shipped 05 is making my

them have worked thus far. What's even more troublesome is that it appears
that 05 uses these new partial classes which would makes rolling back to 03
not possible.

I have a project where a html designer gives me a pile of html to
wire up. I do that and it works fine of course. Then, the html
designer makes a bunch of changes, give me back the revised aspx file
and of course it always gives compiler errors. I've asked the
designer not to remove any controls, div tags etc.
The problem is the errors always point to lines that are not the
problem.
Could someone suggest a better way to work with...

Hi,
I've just encountered a bunch of errors when loading a form in design mode.
These errors have not occured before and don't make sense to me. In
addition, none of my controls are displayed on the form. It's interesting
that the project builds OK and runs properly. I'm concerned that something
in the solution is corrupted. The errors are:
Duplicate declaration of member 'Font'
Duplicate declaration of member 'Location'

Does anybody know how to resolve the following errors? They were
caused by the designer.cs file that was auto-generated by the LINQ to
SQL designer. I am using the March 2007 Orcas CTP version of Visual
Studio.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
