Hi All,

 Got a bit of a strange one.

I have been building an ASP.NET 2.0 app now for quite a while and had everything working quite well untill my computer froze when running the app from the debugger.

Now i get the following error message

 Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

 I have reinstalled Ajax 1.0, reinstalled the toolkit vsi, copied the web config from a working ajax site.

Not sure what else to do, its strange that it suddenly happened!

Any suggestions?

Thanks

Glen

Hi adefwebserver,

Thanks for the post. I'll give that a try. I'm not sure if uninstalling and reinstalling the .net framework will help though as for other web projects they still run. Its just the one I was trying to build at the time my computer locked up.

Still, I'll give it a try and let you know how I go.

Thanks again,

Glen
 

Did you update the Toolkit dll in your website's bin directory? Does creating a fresh new site and adding some Toolkit extender work?

Hi, Thanks for the response.

 I have replaced the toolkit dll in the bin directory of the project.

 
I haven't created a NEW ajax project, but do have an existing project that does work. I have also replaced the web.config file in the problem project with one from the ajax sample website and it still doesnt work.

I have tried to uninstall the framework and also uninstall VS.NET as well but have run into problems with uninstalling VS.NET on Vista (PS Repair doesnt work either). I will keep trying to uninstall VS.NET and then start again.

Any other suggestions are welcomed though!

Thanks again,

Glen
 

Upgrading the Toolkit should be straightforward, a simple binary replacement: http://ajax.asp.net/ajaxtoolkit/Walkthrough/Setup.aspx. You should not need to uninstall and reinstall the framework/VS.NET. Could you use windiff to see what is the difference between the project that works and the one that is giving you this error?

 I had this same issue and was able to resolve it by simply deleting the related files in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files.

I have tried for several hours to resolve this on my machine.

 What resolved it was to delete all files from the following folder:-

 C;\Users\{Your User Name}\AppDate\Local\Microsoft\Temp\Temporary ASP.NET Files\

 Note: You will need to change your Folder Options - in control panel on Vista, to view Hidden and Operating System Files, otherwise you will not find this folder.

Delete all files in the folder and re-run your app. Good luck.

VIsit at  http://www.ginkostyle.blogspot.com/   for answer this works for me

 this work, you have to erase all files, and those who can't be erased... do it manually, file by file

sorry, i talk about this :p

 Perfect. Thank you.

I'm not sure if this is still active, but I had the same problem and my ASP.Net temp file was empty. I had uploaded my site to a remote server, where it worked fine,  and decided to start again by completely deleting my site in my local machine, setting up a new project with the same name and downloading the stuff on the server.  No joy!

The problem clearly arises because something IS there, rather than because something ISN'T (I still don't know what). In the end the solution was very easy - I have MacAfee on  my  machine and I simply got it to do some maintenance by cleaning all my temporary files.  It worked.

Hope this helps someone.
