Wierdenss with digital signatures.

http://blogs.msdn.com/b/raulga/archive/2006/10/30/using-a-digital-signature-as-a-secondary-identity-to-replace-cross-database-ownership-chaining.aspx Greetings. The object names used here reflect the article, though they were of course modified in my environment. So I just completed the above exercise customized for our environment. I skipped the step of creating the sproc in db_source, because it already existed. However, when I would get to this part: ADD SIGNATURE TO [schema_MyApp].[sp_MyApp01] BY CERTIFICATE [cert_MyAppSecIdentity] WITH SIGNATURE = 0x5EF9C30476A8E3E248E9E11B7563528EB02DA1D8F440CAA9141841B9F3101F1988760D2775000CD0D70F44A8672984E327FBF2676E7FAC9AAED8E6F383A98B2A569A407577917E671F3D632EF7326AD3770A32E05CF43A613D310D64B6D52FD978E57A73912BF3587C475E48F4AA58561A7E0DB5D9DB53D35E03EC281BEC7772 go I kept getting the message along the lines of "invalid public key". Of course I changed the sproc name and SIGNATURE according to my environment, so I don't know why there would be an issue? I only got around it when I dropped/ recreate the sproc in db_source, which kind of has me worried. Any ideas?  TIA, ChrisRDBA

Digital Signatures Verification Error


Hey all;


Not 100% sure this is a sharepoint problem, but maybe someone can help.  I am installing a digital signature block that is being made available on a browser form.  The sig is working, but I can not get a valid signature on the form.  I am told there is a Digital Signatures Verification Error. 


Reading other posts tells me that I have to have my signature cert in the trusted Root authority of the sharepoint server.  Here is the rub..


When I use certificate manager, I s

Can SharePoint read/recognize Digital Signatures?

I am using Content Control Mapping to pull certain fields from a Word Document and include it as columns when a document is uploaded into a Document Library. We're using MOSS 2007 and Word 2007. It is required that the user digitally signs the document before uploading.  Is there a way to get the signature to appear as a column in a similar fashion?  Alternately, even just showing that the document was signed would be nice.  I'm new to this mapping business, and Google hasn't been much help. I realize I could use the Collect Signatures workflow, but that seems cumbersome to 1) have the user submit it, 2) have an admin open each document and start the workflow and 3) have the user THEN sign the document.  That's more steps than simply manually opening and verifying digital signatures. I figure I'm missing something obvious here.  Any help or ideas would be appreciated.

Approval Workflow and Digital Signatures


Environment = SharePoint MOSS 2007 Enterprise versio, and Office 2007 Professional/Enterprise

User = SharePoint Collection Admin, Full Control, other users signing and approving have Contribute permission

Settings on Out-of-the-Box (OOB) Approval WF are:  Start manually (no restrictions on manage list permission), Update Approval status on workflow completion, using the Worklfow Tasks list (created by default with the Publish feature enabled)

Documenent library requires content approval and both major and minor versioning are enabled.

Then, in a Word document,  digital signatures are inserted, and the Approval WF is started from within the Word client.  Here is what seems to be odd.  The document is required to be checked out (otherwise the sign operation is not allowed).  Upon checking the document out in order to sign it (no other modifications to the document), the minor version increases...normal behavor for checkout and checkin.  However, in signing a document, we would not want the minor version to change.  Also, the minor version increment is not necessarilly by one.  It might go from 0.1 to 0.3., 0.5., then 0.6 just with one person tasked to sign it and one check out one check in.

Question:  How is the OOB Approval workflow with digital signatures in say Word, really supp

Adding Digital Signatures to repeating sections


I'd like to know if there is someway to accomplish this without going into code behind.

I have tried to put a section into a repeating table but after applying a signature to it the ability to add a new section is lost. I am using a web enabled InfoPath 2007 form.

I selected Allow only one signature and lost the ability to add a new row. The button and text were gone from the reepeating table.

I selected All the signatures are independent (co-sign) and I wasn't able to add a new row to the repeating table. The text and button was there but when cliked got a message reading "This value has been digitally signed and cannot be changed"

I selected Each signature signs the preceding signature (counter-sign) and had the same effect as the co-sign option.

The app keeps making the controls read-only. I turn it off and it goes back to checked.

Any ideas on how to make this work? Or if it is possible?



SharePoint 2010 Collect Signatures workflow - no digital signatures?


Hello, I configured a "Collect Signatures" workflow for the content type "Document", then uploaded a MS Word 2010 (.docx) document as content type "Document".  This Word document as 2 empty Signature Line in it.

I then start the workflow, basically 2-stage with 2 person from my Active Directory.  However, what I found is that when I go to my workflow task and click on the "This document requires your signature" link, it pops up a "Workflow Task" box in the browser.  There is a "Sign" button which I can click to sign but it does not sign on the signature lines inside my Word document.

What am I doing wrong here?  Or does SharePoint 2010 Collect Signatures workflow no longer work with digital sigantures?  Thanks.

Is there a limit in the number of digital signatures?


Is there a limit to the number of different digital signature lines/sections you can add to a form? They would like 8 different signature lines/sections  for various reasons and on the last few I can't seem to add any more. They all wind up using the same digital signature data to sign, if i change one they all change..

Thanks for any help...

Graphics: Manipulate Digital Images in Internet Explorer with the DirectX Transform SDK


The Microsoft DirectX Transform is a Microsoft DirectX media API that can be used to create animated effects as well as to create and edit digital images for Windows-based applications. Scripting and HTML can be used to display an existing transform on a Web page, and improved transform support in Microsoft Internet Explorer 5.5 makes it easy to use transforms. This article provides step-by-step instructions for writing a transform as an ATL project and shows an example of an image transform. C++ is used to instantiate, configure, and display transforms in this project.

Digital Dashboards: Web Parts Integrate with Internet Explorer and Outlook to Build Personal Portals


Digital dashboards gather information and functionalities from a wide variety of sources ranging from Web pages to applications such as Microsoft Outlook and SQL Server, and present the resulting information in a single user interface. Digital dashboards built with the Digital Dashboard Resource Kit (DDRK) are made up of distinct units called Web Parts. Web Parts, introduced with the DDRK 2.01, can contain any Web-based information, are reusable, and integrate with each other and with other dashboards. Creating Web Parts and getting them to work together is illustrated via a sample application that uses a PivotTable view. Integrating Web Parts with Outlook, the Outlook View control, storage, and debugging are also covered.
