    Question

  • Hi,
    When I trying to open my Form (Design) in VS2005, Iam getting an error like "Illegal Characters in Path". Actually my form is developed in VS 2003, and that was migrated by my coleague into VS 2005, In his system it is working fine.
    Recently I upgraded with VS 2005 in my system, That migrated form cannot visible in my VS2005 design view, Iam able to view the code and also able to Run the application, but In design view Iam unable to View the form, instead form Iam getting an error like:

    One or 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.

    Illegal characters in path.

    Hi,

    Take backup of following registry key and replace them in your pc. But it is not working for me. But you can try it.

     

    Take backup of HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\.NETFRAMEWORK : From Working PC

    And Replace it in your PC

  • Hi,

    for me this problem was resolved, this is really a Bad Bad error, I suffered with this alot.

    If you use any third party controls, that problem will occur, because of some license issues,

    to overcome the error please do the following steps

    step 1:Add reference -->Design dll's of that controls need to be referenced to the project

    step 2: open the form in design view (the one which showing the Illegal error).

    step 3: delete .Resx file

    step 4: then again open the form.

    I think this process might help you

     

    thanks,

    Hi Jyothi,

     

    There is no third party control on the form. Form is empty and in the project also no third party control is referenced. I tried deleting .Resx file, reinstalling Compact framework .... but not able to solve the problem. You can visit following URL if you want to earn points.

     

    Do you have any other solution ?
