Our entire team is having the same exact problem. Your solution was encouraging, however, it only solves the problem between rebuilds. If I do another "re-build", I then have to restart VS2005 again. Is there a work-around that solves this once and for all? Thanks.

Well, i dont have any permament solution to this till now. Other way is you go to Solution -> Clean Solution and rebuild it. Again your designer forms should be closed while doing this. This should also work. If i get a permanent solution to this, i'll post it here.

I believe the problem is caused by the Indexing Service locking the obj and bin files, trying to reindex their contents. Simply select your Projects folder in Explorer, go to Properties..., click the Advanced button and disable the checkbox to allow the indexing of the folder and subdirectories and files.

Ian's solution worked for me so I'm happy :-) Thanks a lot.

Thats great, been struggling with that this morning and both those solutions helped. Thank you.

Ur the best > this solutions did it > dont forget to use the windows explorer

Thanks!!!!
I was able to open my form which was upgraded from VS2003 with disable indexing.
I don't need to get an order hotfix.

Didn't work for me. I turned off indexing on the folders and I checked and I had already turned off the indexing service so this couldn't have been the problem. Is there another fix?

this appears to work sometimes... Thanks.

WOOOOOORD!
God, this is the most annoying bug, thanks for the fix!

There is actually a patch for this from Microsoft. But you have to have a support plan to get them to send it to you.

Oh yeah, it's:
VS.NET 2005 Hotfix 265517_ENU_i386

Ya i was also having the same proble for me
the first solution i.e. to delete the bin and object folder and rebuliding the application
worked thanks a lot

hi freind

even i was getting this error frequently

one solution was deleting the object and bin folder and open the solution and rebuild the project

it worked fine but it was still creating problems because in my project i was referecing some 3 or 4 assemblies

so project still wasn't running properly

change the references might work but still not sure



The solution i have found for this is whenever such an error occurs

i immediately open the same solution in another instance of vs.net 2005 without doing anything eg. rebuilding or cleaning the solution

and that works fine for me and i just close my older vs.net 2005 instance without any save

I ran into this issue, similar but with different cause. it was cause by I add a class (say name Dataclass) in the same .cs file which is a winform. If I add Dataclass on the top of the cs file, I ran into problem not be able to display the winform in design view, but If I move the Dataclass to the bottom of the cs file, it fixed the problem.

Could someone send me that hotfix?

Great help, thanks

Hey Ivan & Shreeve,

Have you managed to resolve the problem? I'm also stuck with this :(

I got this problem too, but a little different. On two different forms I added one from two self created components, just simple panels with TextBoxs, Buttons, Label etc. If I open these two forms I got the error message. All other forms can be opened without problems. The whole solution compiles and runs very fine. :-(

hi all, i have same problem with different error message and i face this problem when i put the datagrid on which i have applied some skins...i disabled the indexing option but it's still not working.can anybody help me?? pls find out some solution.
the error message i got,

thanx

Me too faced the same problem.

I used to close the design window and open it by right-click the file from "Solution Explorer" and select "View Design" instead of using short-cut keys. This works for me several times. But if the design really has some bug, then you've to remove/edit the code manually to overcome this issue.

Switching folder indexing off worked for me too! It's always great to find such a simple fix for such nasty, nerve wracking little problems... :-\

We had this issue in our project couple of months ago.
The problem we had was Dev environment dlls went out of sync.Contact microsoft for right version of dlls.We had this issue after we installed sp1.Versions went out of sync and screwed up whole GUI.When loading forms GUI is looking at wrong dlls.

Does anyone already have the path, the VS.NET 2005 Hotfix 265517_ENU_i386???? All the solutions solutions doesn't work with me, can any one that have it post a link?????
Thanks
JF

Yeah, i submit too. Neither of the solutions above work for me. From time to time i have this thing going on, except for the one with the restart of VS and that's unacceptable.

Does anyone have the path to the patch? or that ..design.dll that's beeing patched. pleeeeeeeaase!!!!!

... i would be very gratefull
it would be a good did for the man kind

Hi,

Me too faced the same problem.
I solved it with installing the SP1 for Visual Studio 2005.
File: VS80sp1-KB926601-X86-ENU.exe from the Microsoft Download Sides.

First I rebuild - didnt work Then clean, remove indexing => dint work.
Closing all and restarting VS -> Then it was OK
(dont know wether index off cahnged anything but I hope ist OK now)
Also for me - its only buggy on some forms with custom controls
Thanks a lot for the ideas !

The class Form1 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.

i got this error.I tried all the solutions above.Dint work.Help me out pls??

I figured this problem out at least for me. In my usercontrol I had a public property that was given a value of nothing by the designer. the nothing value was causing the null reference.

hope this helps.

Thanks tat solved the issue. I just tried to find the error control using the find text option. (System.Windows.Forms.AxHost...) in the whole project and i just kept commeting the controls initialisation and other events.. I kept doing this in all forms which had error. Finally i rebulit it and restarted my VS2005. After tat i could see the design page..

for those who still have an issue with their VS 2005. here is the patch link http://code.msdn.microsoft.com/KB912019/Release/ProjectReleases.aspx?ReleaseId=753

hi , many thanks to you
i had same problem ! for unknown reason i get this error ,
i do your steps , but i find before close the vs and delete folders we should open the forms in design mode to solve the problem after opening and bulid vs again !
