    Form designer problem - cannot load a form

    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.

    Look at the lines all are referencing the system things such as

      Re: Form designer problem - cannot load a form

      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.
