The dreaded asp.clipboard

Hello all

I have the need to copy something to the clipboard via 3rd party type library and then pick it up on the .NET side via the clipboard (all server-side). To complicate the issue, the application needs to be web oriented (ASP.NET)

I have a console version that work, but I can't seem to get the ASP side working. I have included the Forms assembly and I'm able to write to the clipboard via the 3rd party, but the clipboard is always unassigned (null) in ASP.NET when in fact the clipboard can be pasted into PhotoShop

I've searched a lot of articles about this issue. Some suggest that it's a permissions issue. To rule out permissions, I have the site impersonate. The impersonating identity is myself and since I can past into Photoshop, I can only assume my identity has access to the clipboard

Any insight is appreciated

Thanks
Bilthis is a permissions issue. your aspnet account needs permission to
manipulate system resources on the desktop

Alvin,
Thanks for the response

Maybe I'm missing something else then. Before impersionation I tried setting the processModel user to SYSTEM, and had the same problem. I have also added the ASPNET account to the 'run as part of the operation system' policy with no luck

When I call, clipboardData.GetDataPresent(DataFormats.Bitmap) the exception being returned is null object (Object reference not set to an instance of an object.). The most likely cause is permissions, but as far as I can tell I've tried giving the adequate permissions - or am I missing something

Thanks again
Bill
can you impersonate to an authenticated user and see if this works?

Otherwise post your code and i'll work with you on it

the dreaded WAT is not working

Hi folks, using ASP.net 2.0 VS 2005 and C# on XP pro
I'm using a file based ASP.net web type on my local machine
I've not had this problem before, but I started a brand new website and I
clicked on the ASP.net configuration icon in solution explorer and I get thi
s
message
'An error was encountered. Please return to the previous page and try again.
'
when I click the link that says 'how do I use this tool' I get the message
that 'the tool has timed out'
how can I make this flaky heap of junk show me the normal 4 tabs
regards and many thanks in advance
CharlesAASP.Net requires a web server running the ASP.Net ISAPI to work. It is
HTTP-Protocol-based, and can not be run as a file-based web.

Did you create the membership database with the aspnet_regsql tool ?
If you have not yet created the membership database, exit the Web Site
Administration tool, use the aspnet_regsql command-line utility to create
and configure the database, and then return to the WAT to set the provider.
aspnet_regsql.exe is located in the .Net Framework directory :
Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

Kevin, are you sure about that? I seem to remember using it on a machine the
other day (not my home one) with a file based system
Juan, surely I don't have to create the database first, how does the WAT
tool know that I want to do data stuff, I might just want to change some
config type things
I'm willing to give it a go, but I thought that the WAT tool itself created
the databases in App_data and that you used aspnet_regsql to change the
location of the database
Thanks for your posts so far any further reaction to what I've said here
would be really appreciated

You can use file-based web in ASP.NET 2.0 only (not 1.1), and only from
Visual Studio, because it has a built-in development web server. You
cannot however run ASP.NET based pages/services using the file:// protocol.
So you're both right ;-)

i am indeed using http://
I moved to a local IIS based website (through a virtual dir) and there I
can't even see my default.aspx let alone use the WAT
this is the error I get
This error (HTTP 500 Internal Server Error) means that the website you are
visiting had a server problem which prevented the webpage from displaying.
despite having used added in MAIN\ASPNET (main is my machine name) into the

I had none of these security probs in .net 1.1, now with VS 2005 I can't use
my local IIS anymore and if I try to use the WAT I'm told that it has timed

re:
> I might just want to change some config type things
There's very little you can change in web.config using the WAT.
If that's all you want to do, change the website to http-based,
and use the ASP.NET configuration manager in the MMC.
Using the WAT for minor web.config configuration changes is spotty,
at best, since there's a lot of settings you don't have access to from the W
AT tool.

The dreaded back button

Within an application, is there any way to "tamper" with the history of URLs retained by the browser, so that I can control the URL associated with the back button?

I guess this would entail deleting the last page from the linked list that the browser holds for pages that I do not wish to revisit.

Is this possible?Because of security reasons, you can't get the history from the client.

Thanks for the response.
Maybe I'm missing something else then. Before impersionation I tried settin
g the processModel user to SYSTEM, and had the same problem. I have also ad
ded the ASPNET account to the 'run as part of the operation system' policy w
ith no luck.
When I call, clipboardData.GetDataPresent(DataFormats.Bitmap) the exception
being returned is null object (Object reference not set to an instance of an
object.). The most likely cause is permissions, but as far as I can tell I
've tried giving the adequa
te permissions - or am I missing something?
