XBAP App Full Permissions And Still Got Errors?
Aug 16, 2010
We have a small XBAP file upload app that we are having trouble deploying. We were getting security errors when we were pushing this application that we don't get when running in our development environments on our machines. We gave the XBAP app full permissions and still got errors. Then we created a personal certificate and were able to get this to work. But that means we have to load a client side certificate for each and every machine that wants to run this which is ridiculous.

It is possible to embed an XBAP application into an IFrame, this is rather easy !!The problem however is that it renders on top of anything within the web application. For example!I have a menu in my web application which can collapse when I hover above it, but it will collapse UNDER the IFrame when it needs to collapse ON TOP of the IFrame with the XBAP Application in it. I tried messing with the z-index but this does not fix anything

I'm working on a UI for a simple inventory system. The users will use a USB barcode scanner to retrieve an ID and then either retrieve information from the database about the scanned object or enter the new information. This will only be used within our corporate environment. I can't decide which is the best way to go with this. I would like to use this opportunity to take a crack at WPF.

I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored
[code]....
This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.

I use the code, to display the file that I saved in the database.the question is: why the file can not be performed with a full screen.
protected void View(object sender, EventArgs e)
{
int peraturan_id = int.Parse((sender as LinkButton).CommandArgument);
Session["peraturan_id"] = peraturan_id;
ClientScript.RegisterStartupScript(this.GetType(), "open", "window.open('file_view.aspx','_blank' );", true);
}

When I build my program, if there's one error that prevents it from running, instead of just getting the one error I'll get around 50 additional errors in addition to the real one such as:
Error 27 Validation (XHTML 1.0 Transitional): This name contains uppercase characters, which is not allowed.
Is there any way to not show these?

Is it possible to use a small .NET page to set folder permissions on some folders on the server where it resides? What is the code or objects that can be used for this? I am on Windows Server 2003.
Basically I want to hit the page with a GET or POST and have it run and check and/or update the permissions on a folder.

I am calling example.exe from asp.net web-page. Example.exe contains Process.Kill(), but I am not able to kill that process whenever Ill run example.exe from asp.net web page. I think i need to set some permissions for killing processes. What permissions must a user have to be able to succesffuly execute a rocess.Kill? Note : it is working when I double clicking on (example.exe), means its killing some processes

We have a web application that runs on a WIndows Server 2008 64 bits machine. The app's ApplicationPool is running under the ApplicationPoolIdentity and configured for .net 2 and Classic pipeline mode.
This works fine up to the moment that XmlSerialization requires creation of Serializer assemblies where MEF is being used to create a collection of knowntypes.
To remedy this I was hoping that granting the ApplicationPoolIdentity rights to the ASP.Net Temporary Files directory would be enough, but alas..
What I did was the run the following command from a cmd prompt:
icacls "c:windowsmicrosoft.netframework64v2.0.50727Temporary ASP.NET Files" /grant "IIS AppPoolMyAppPool":(M)
Obviously this did not work, otherwise you would not be reading this :)
Strange thing is that whenever I grant the Users or even more specific, the Authenticated Users Group those permissions, it works. What's weird as well (in my eyes) is that before I started granting access the ApplicationPoolIdentity was already a member of IIS_IUSRS which does have Modify rights for the temporary asp files directory.
And now I'm left wondering why this situation requires Modify rights for the Authenticated Users group. I thought it could be because the apppool account was missing additional rights (googling for this returned some results, so I tried those), but granting the ApplicationPoolIdentity modification rights to the WindowsTemp directory and/or the application directory itself did not fix it.
For now we have a workaround, but I hate that I don't know what is exactly going on here, so I was hoping any of you guys could shed some light on this.

I'm uploading an Excel file and then reading data using oledb connection in asp.net but I'm getting the following error: The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data.
Dim ocmd As New OleDbCommand("select * from [Sheet1$]", conn)
Line 12: conn.Open()
Line 13: Dim odr As OleDbDataReader = ocmd.ExecuteReader()
conn.open() line is red highlighted for error.
The excel file is uploaded successfully and present in the folder.

I am doing some testing and want to find out best practice for creating a new user to assign to an appPool. I know that the default ASPNET account, on IIS 6.0, is very low permissions. For experienced folks, what are the bare permissions required to grant this new user? Yes, I am aware that various NTFS rights are required for different operations, such as reading outside of the application path, writing to the NTFS share, etc. I am just looking at a base install.
Dino Esposito wrote in Chapter 15 of Programming Microsoft ASP.NET 2.0 - Core Reference that the following directories would need the respective permissions:
.NET framework root - read/list Temporary ASP.NET folders - full GAC - read Windows System32 - access/read App root - access/read Web site root - scanWhat else would I need to set up beyond this base configuration as far as rights are concerned? If anyone does this regularly, do you have a script to do this automatically?

I've recently installed VS 2003 to work on an existing web project (I already had 2005 and 2008 installed), but I'm getting an annoying problem when I try to run it. I get a browser page with an error message of:
Code:
Required permissions cannot be acquired.It then pinpoints the problem as being in line 198 of my machine.config, which is:
Code:
<add assembly=*/>
I've changed the ASP.Net version to 1.1.4322 in the appropriate places, and other people in the team can run the project happily using an identical machine.config (they used a copy of mine).

I've got a routine that tries to import files from an import directory, spitting them out to an Error directory if the import fails. The Error directory is shared and users have access permissions to delete files in there, so they can try to fix the problems and then move the files off to the import directory again. I use File.Move to move the files to the Error directory and this is working fine, apart from the permissions - it seems to revert to a default set of permissions, rather than the directory's one, and so the users can't remove the files - how can I reset the permissions on the file to those of their containing directory? I've tried poking around with SetAccessControl and SetAccessRuleProtection but I don't seem to be having any luck?

I have an ASP.NET 4 site that uses the new SQL CE 4 CTP. The site works fine locally (IIS 7.5 on Win7) and fine in Server 2003/IIS 6. It fails when deploying to IIS 7 on Server 2008. The error I get is:
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
The interesting thing is if I switch the app pool user from its default user to LocalSystem, everything works great. So clearly there is a permissions problem somewhere.
Long story short, does anyone know what special permissions need to be set when deploying a SQL CE 4 database? (BTW, we have already set r/w access on the db itself and on c:windows emp)

I am using windows authentication without impersonation on my company's intranet website with IIS7.
Under IIS7, what account is used to access the folder which contains my web app using these settings?
Would it be IIS_IUSRS? Or NETWORK SERVICE? Or another I don't know about?

The website has a separate application pool defined for it running under the Network Service account. I have checked the settings for the virtual directory for the application but nothing seems wrong. I have tried defining the trust level in web.config to full trust but this does not fix the issue. I have looked into defining the trust level for the application through the machine.config file but I am unsure of how to proceed with this.

We use a build tool, TeamCity to do our builds. I have a directory locally with javascript files that works fine, but when its built and pushed to our test server and I try to get to any files in the directory I get: 401 - Unauthorized: Access is denied due to invalid credentials.
I've changed permissions several time on the server (2008/IIS 7) and still the problem persists. I have other directories that have javascripts and when I put the path into the browser for them I get the source.

I have my SqlServer 2005 database at a web host. I recently figured out how to set permissions for the stored procedures (see this link if you face the same problem:
[URL]
Now I wonder: What permissions should I give the website's visitors?
In a stored procedure's Properties window, I have three availabale users, the db owner (the db name), "guest" and "public". My bet is on public.
As far as permission types go, I hev the following available:
Alter, Control, Execute, Take Ownership, and View Definition. My guess is that the one of interest is Execute, correct?
In other words, should I set all stored procedures to Execute for public (not that I seem to have the permission to do that myself - I get an error message when I try to alter them)? If so, could I ask the web host to set them globally for me? Or should I only set stored procedure using UPDATE/INSERT/DELETE to Execute?

The .NET trust levels for the application are set to "Full" both for the site and globally and I have set the trust level in web.config (system.web/trust) to Full.
