Web Forms :: Insert An Image Into A PDF. Acces Denied! System.UnauthorizedAccessException?
Jul 20, 2010
I'm trying to insert an image into a PDF, when I'm creating it. It works fine at localhost. But when I try i on server, it crash at the line of inserting image.
I've tried with:
Dim stream As IO.Stream = IO.File.Open(Server.MapPath("~/Imagenes/Cabeceras/LogoPresfiap.jpg"), IO.FileMode.Open)or
Dim stream As IO.Stream = IO.File.Open(Server.MapPath("~/../../Cabeceras/LogoPresfiap.jpg"), IO.FileMode.Open)No sucess. It throws me an error Acces denied:
I'm a lowly DBA.I am supporting a web app that allows users to upload images (among other documents). The system is deployed and working and not having issues with the uploads. However, I upgraded my development box recently and since then I have been encountering an "access denied" issue. Initially I thought it was a simple security issue but now it seems it is more complex.
I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command:
Dim proc As New System.Diagnostics.Process proc.StartInfo.RedirectStandardOutput = True proc.StartInfo.RedirectStandardError = True proc.StartInfo.FileName = "C:Program Files (x86)ImageMagick-6.6.1-Q16convert.exe" proc.StartInfo.UseShellExecute = False proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _ Server.MapPath("~/certificates/temp/test-1234.jpg")) proc.StartInfo.CreateNoWindow = True proc.Start()
I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server?
I have an application that uses its own authorization to determine if a user has access to pages. I want to display a more friendly "access denied" page in the event that access denied. In the MasterPage...

I get the error below. To me it looks like I'm not allowed to, or the error is a result of just trying to instantiate the UnauthorizedAccessException() class,Attempted to perform an unauthorized operation.
Exception Details: System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
I have set up a simple bit of code to upload an image to the web server. It works offline without a hitch but online I get an error saying denied access.I am not overly surprised to be honest as I have not configured anything on the server (through my web host "Mochahost") to allow unknown users to upload files. I wonder if someone could point me in the right direction.
I have a Subscriber form defined on Webserver1, http://localhost/validation/Subscription. In this form there is a textbox - FirstName and some hidden controls I have a Services webform defined on Webserver2,http://localhost/Number/Services. I load the content of page "Subscriber.aspx" from Webform 1 to webpage Services.aspx on Webserver2.
I have an existing application that was written in .NET 3.5. The piece of code in question is using the FileUpload control and its SaveAs method. Its worked perfectly for the past six months, but I've recently upgraded the project to .NET 4.0 and I'm now receiving an "Access to path (...) is denied" every time the method is called. It works fine locally in dev mode but fails on my prod server. I've upgraded the website to run under .NET 4.0 and I've made sure the account (Network Service) it runs under in the app pool has full control. Other than upgrading to .NET 4.0, nothing has changed for the project.
But when I upload image with Fileupload and click on btnupload button below error happen..

When I move some web-based code from VS2008 to VS2010, I find it is different when it is hard to handle the Image class.
Let's take the following code as an example.
[Code]....
As I have already imported the System.Drawing namespace, I still cannot use Image.FromFile method as VS2010 detectss the Image class is in System.Web.UI.WebControls namespace.I have lots of such a kind of code in my project using Image class and I will get messed if need to modify the code from
I have a service which reads an image stored in the database. I want to be able to read an image stored on the file system and return that back to the requestor.
How to add System.Drawing.Image object to Asp:Image Control but I dint have imageId in my table.Image field is in another table..i retrieve image from database in Image object.i want to display it in asp:Image control or grid view.how to do it?
System.Drawing.Image newImage; using (MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length)) { ms.Write(imageBytes, 0, imageBytes.Length); newImage = System.Drawing.Image.FromStream(ms, true); }
and now I need to have this image as a source for asp:Image (System.Web.UI.WebControls.Image). Is this possible as I know that conversion is impossible?
I'm a newbie to Asp.net,learning from the Apress's Begining Asp.net...book.While very curious to see an image given by me on the browser,I'm stuck at the very first step,Configuration : Win7(32-bit),VS2008 Pro/.net 3.5,Firefox as default browser.Now,In created a simple website(not web app) in C#,added three images(.png,.jpg,.gif) to the App_Data folder(using the solutn. explorer of course).Then added the Image control from the toolbox & in the ImageUrl property, selected one of the images->presses f5 to start in debugging mode but every time the browser displays the alternate text given by me.
When a FormView control is in insert mode, a data entry form is shown where the user will type a value into each textbox corresponding to a table column.
How do I disable data entry for one of these textboxes and instead, assign a system-calculated value to that text box?
question about how to use MS Access as the aspnetdb.mdb during a login and authentication with the use of VS 2010 with framework 3.5. Reason: My current provider does not support MS SQL and only ms Access and MySQL as databases.I wanted to implement a login and authentication and based upon an artikel about ASP.net 2.0 i saw, that basically Access was the first choice in those days.Is it still possible to use Access? and how to implement this?Is this a matter of using connectionstrings inside web.config with Microsoft.ACE.OLEDB.12.0 ?Hope that i get an answer which i understand, since my knowledge about these things is not that big.
