.NET, Office Automation And .NET Framework 4.0?

Aug 10, 2010

I am trying to figure out if the disclaimer below still applies to the .NET Framework 4.0:Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

I was under the impression that the new version of the Framework uses some magic to avoid PIA deployment and somehow one is allowed to manipulate Interop objects ... I do not know enough to figure this on my own. The simple question is: is it possible to open an Excel workbook from within an ASP.NET page, change something in it, save it and do not blow anything in the process?

VS 2010 - Word Automation On Server

Jul 16, 2012

I would like to generate word reports on the web server. My web host does not have office installed, and from what I've read it´s not recommended to use word on the server.

Now, I just recently found this out, and I more or less counted on the reporting stuff being quite simple to set up.

This is what I need.

The user logs in and uploads data, changes it, calculates it and so on. When this is done he will need to generate a report, although preferably in a format he can edit (like maybe adding a comment or a logo or whatever).

How do I do this? This really needs to look professional so features like page breaks and other kinds of formatting is needed.

It is sufficient if the document is generated and not opened on the server. I think I can require the user to have office installed locally in order to actually open the document and maybe print it. But the content must be generated from the sql database.

Configuration :: Word Automation On Server Side?

Dec 28, 2010

I created a web application in which I am generating a ms-word document using Microsoft.Office.Interop.Word dll. The application is running fine in the visual studio but when I tried to run on IIS 5.0 through virtual directory then its giving the following error -

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005.

In my application I have taken reference of Microsoft Word 12.0 Object Library, but its coming as Microsoft.Office.Interop.Word dll, this interop dll is just a wrapper of the actual word COM dll. But I have to register the actual word COM dll. so my problem is to find -

1) The path of the original word dll(COM)

2) How to register this dll, either using regsvr32 or to register on IIS.

Silverlight 4.0 - How To Find A Silvlerlight Object On Page Using Microsoft UI Automation Testing

Aug 4, 2010

I have an object on my asp.net page hosting a Silverlight xap (in my particular case it is in an IFrame, but I'm curious about regular objects as well). I can find the element in UI Spy, but the name just says "Silverlight Control". Trying to find that AutomationElement in my automated test is unsuccessful (control is null every time). Is there a setting in the Silverlight code or in the html that would help? How can I distinguish it if there are multiple Silverlight controls on the same page?

<object id="silverlightClient" style="display:none;" data="data:application/x-silverlight-2," type="application/x-silverlight-2">
<param name="source" value="../../ClientBin/SilverlightApplication.xap"/>
<param name="onerror" value="onSilverlightError" />
<param name="background" value="#00000000" />
<param name="minRuntimeVersion" value="4.0.41019.0" />
<param name="autoUpgrade" value="true" />
<param name="windowless" value="false" />
</object>
TreeWalker tw = new TreeWalker(new System.Windows.Automation.PropertyCondition(AutomationElement.NameProperty, "Silverlight Control));
AutomationElement control = tw.GetFirstChild(ancestor);

UI Spy

Identification
ClassName: "MicrosoftSilverlight"
ControlType: "ControlType.Window"
Culture: "(null)"
AutomationId: "71857844"
LocalizedControlType: "window"
Name: "Silverlight Control"
ProcessId: "7636 (iexplore)"
RuntimeId: "42 2163886"
IsPassword: "False"
IsControlElement: "True"
IsContentElement: "True"


EDIT: added image, I also realized that the object is inside of an IFrame. UISpyImage - title name removed

I have an old COM+ object that we've used to create AD user accounts with information from our HR system.

After modifying the code I am unable to get an account to be crated and the following error appears:error '8007202f' Automation error A constraint violation occurredI am not a developer and I know that this is a long shot but if anyone has any insight into if this is an AD issue or one with VB 6, any help at all would be greatly appreciated.

Configuration :: Executing Office In IIS 7.0?

Aug 18, 2010

I've got a website that needs to create an Excel File using the Excel object library and then makes it available for download by the user.This of course works fine in my dev environment on my local machine. I getCould not load file or assembly 'office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.

The machine is running 64 bit Windows 2008 Server, and the version of office is 2003 SP3 (yes I know its old, but it does run normally). I'm thinking its a registration issue, but I don't know how to register Excel with the site in IIS 7.0.The development machine (on which everything runs fine), is an XP box. I've noticed that Excel is installed to a different path on the Server 'C:Program Files (x86)Microsoft OfficeOFFICE11' as opposed to 'C:Program FilesMicrosoft OfficeOFFICE11' on the XP box.

Running Into A .NET COMException With MS Office Interop?

Feb 16, 2010

I am trying to work with the Windows clipboard and Office Interop in an ASP.NET web application.Everything works well on my local machine running XP (i have created a Windows application first which ran perfectly well on local machine). Then I have executed it on a server running Windows Server 2003 and it worked there as well.Then I made a ASP.NET sample project and it worked on my local machine. However when this time I deployed it at the server, after banging my head with permissions, it started giving me this exception which i have no idea why it is doing this:

System.Runtime.InteropServices.COMException (0x80048240):
Shapes (unknown member): Invalid request. Clipboard is empty or
contains data which may not be pasted here.
at Microsoft.Office.Interop.PowerPoint.Shapes.Paste()

Is the problem with any sort of permissions again on clipboard? If yes, how can I grant appropriate permissions?

Convert From Office Docs / PDFS To HTML

Jul 27, 2010

I am currently working on a project where I need to secure access to downloadable files. The solution I want to implement is to have two buttons next to each document. One that says Editable and the other read-only (depending on the users permission they will see one of these or both). The editable will work normally with the browser dialogue opening to say open / save the document. That is the easy part. The read-only button needs to open the document without caching anything (in temporary internet files) on the client's machine for security reasons or give the ability to save it to their local machine.

The best Idea I have for this is to convert the document to HTML on the fly and then redirect the user to this page. We can then turn caching off on the site so the HTML isn't cached (I know they can then right-click and save the HTML or copy the text,etc.. but that is deemed acceptable). Does anyone have an alternative solution than this (or have an easy way this can be achieved)? I don't want to install Office on the web server or pay heavily for a third-party tool like Aspose.

Configuration :: User Rights When Running Office?

Aug 31, 2010

I've got an ASP 4.0 website running on IIS 7.0 . Part of the web site creates an Excel document using C#, due to company policy I'm stuck with Excel 2003. I've noticed that when I deploy the site and use the part that creates the Excel file, its running Excel application object with the login of the user accessing the site. This causes problems with access rights to the Server.

How do I set the server up to run the Excel application using a fixed account? I've got the Application pool running under one, and I thought that would solve the problem, but it doesn't seem to.

Once a node is clicked the corresponding document loads in an iframe to the right of the tree.

They would like the document to resize the way that the pdf's do inside the iframe.

Security :: Restrict Access To Site From Outside Office?

Nov 9, 2010

I am faced with a rather tricky issue. I am developing a web application that resides beneath a web site. The web application is actually meant for the employees of the company owning the web site. The employees can access the web app from the login facility on the site.

The situation demands that an employee must be able to login to the app only from the office machines and not from anywhere outside. I thought of a logic where in the IP address of the machine in which the employee sits will be stored against the employee profile and when he logs in, the authentication will check for user credentials as well as whether he is logging from the designated IP. If not he is not allowed access to the app even if the login credentials where correct.

I am not sure if this is a good way, because I feel tricky persons can give the same IP of the office machine in another machine, say at home and the logic is broken. Can somebody provide me a better way of solving the issue. I am using ASP.Net login control for user login.
