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
