I got this kind of error recently:
When I tried to open a form I got error something like this:
One of more errors encountered while loading the designer. The errors are
listed below. Some errors can be fixed by rebuilding your project, while
others may require code changes.

Any hints ?

There are some things u can do.
1.) rebuild the project and try to open the form
2.) if that fails close VS and open it again
3.) may be there is a bug inside the serialized data in the resx file.
4.) u have a property inside a custom control that needs some other
initialization that the designer can't do
If you have a problem with designer and serialized properties of
costomcontrols see the DesignerSeriali zationVisibilit y attribute.
Hi,
I have tried several times say up to 5 or 6 times close solutions, close VS
and reopen, then it fixed. This error suddenly happened.
For (3), how to figure out what is the bug if ther is any?
For (4), how do I know which properties ?
How to read/see DesignerSeriali zationVisibilit y ?
This is my situation, in my solution I got several projects (DLL), some DLL
will be referenced by other DLL projects (added in the references). I first
encountered it some days ago, then I moved the whole solution in another
folder, reopen the form with no error. However, then sometime later reopened
with error again.

Serialzationpro blem: look at the resx file generated from designer and
search for serealized data.
If u have a dll that needs an other dll add both to the list of
references
I opened the resx of my form and found only one entry in the table:
FolderBrowserDi alog.
Now the situation getting worse, every form in my current project cannot be
opened, all have errors.
Other projects in my solution are fine opening the forms with no error.

I often get spurious errors; in other threads the cure is to close VS,
delete the bin and obj folders, open VS, build the project and voila! the
designer works again. Has never failed me yet.

Hi folks!
I have a BaseForm class that inherits System.Windows.Forms.Form. It has a
property, whose value I need supplied by the class that inherits it. The
BaseForm usees the value supplied into this property in its Load event.
So, I gave the BaseForm and the property 'abstract' modifier, and put the
implementation of the property in the inherited class; say MyForm. However,
when I did this, I no longer can open MyForm in the design...

I'm using VS.net 2003 and having trouble with the following:

I have a form that when opened in the designer appears of the screen. The

Hi,
I have a custom form that works fine when I debug it or run it in release

the designer when no control is on it, but the resizing tool (in the
designer) is offset both horizontally and vertically and when I put a
control on it, as soon as I save, the designer throws an exception (but
cannot be reproduced everytime) and the form cannot be loaded anymore unless...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
