Advanced Basics: Digital Grandma

  

As a parent of a young child, I take a lot of pictures-many more than anyone would ever be interested in seeing. Well, anyone except my mother. This is her first grandchild and the one or two pictures I send to her each week only brush the surface of her grandmotherly needs.

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.

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.

Microsoft Office 2000: Create Dynamic Digital Dashboards Using Office, OLAP, and DHTML

  

Digital Dashboards provide users with one single interface through which they can view information from a variety of sources that have been chosen specifically for that user. In addition, dashboards allow a user to view the information offline, adding portability to the mix. This article discusses options for building a dashboard based on the Microsoft Outlook folder home pages feature. It covers culling the data from disparate sources and storing it using the MSDE. It then discusses the creation of nugget definitions for structuring the data, and providing a synchronization mechanism to update to the data stores.

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

SharePoint read/recognize a Digital Signature in Word (XML Content Control Mapping)?

  
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?  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.

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 Signing of Forms (not template) changes status of form

  
I have a nice InfoPath Travel Request form that requires sequential digital signing.  I have the sections holding the signatures display contingent upon the prior signed section having a value of being signed.  All is working well. Now, once I publish the form to a SharePoint Form Library, I'd like to have a column showing a status such as 'Supervisor Approved', then on to 'Manager Approved' to finally 'Fully Approved'. I thought that I could create a Rule that when a section's digital signature value changes to 'signed', it could update a 'Status' field's text value.  However, when in practice, if digital signature is applied, there is no method to update the 'Status' field.  Digital signatures apply to Sections and sections don't have Rules capabilities. Other than writing code, is there a method that I can use that would change a 'Status' field value based on a section being digitaly signed?Greg Appelt
