  I am having difficulties signing the manifests in ClickOnce.

• Visual Studio Tools for Office Access/Create DOM for MailItem.HTMLBody and Open Contact by EntryID

  Hello, I have two questions, I wish to modify the html of a mail item when it is read in Outlook (so I can hyperlink key words, similar to Smart Tags). There are issues though when I straight modify it because it messes up the html. The best way seems to be to access the DOM. Does anyone know how I can do this Should I load the html first up into a web browser control OR is there a way to use Smart Tags when reading e-mails Second question: How can I open a contact by an EntryID I don't think looping through the contacts would be very efficient...so I was hoping to find a better way. Thanks! Modifying the ...Show All

  I am working on a Pocket PC app.  Using the Mobel Application Development Toolkit and writing it is VB.  What I am trying to do is add an image to a button.  I notice that there are not any properties for the button to do this (or function, or members).  Also there is no help on trying to do this in any other way.

• Software Development for Windows Vista promote a transaction to DTC

  Is there a way to forcefully promote a transaction to become a distributed transaction Because I got some code that runs flawlessly on Oracle and MS SQL Server 2000, but bombs out on SQL Server 2005 because the transaction logic tries to be too smart and fails doing so. The situation is that object A is opening a SQL connection and a reader while reading it comes to a situation where it creates object B which opens another connection to another database. On SQL Server 2000 and Oracle that works flawlessly, in my understanding because the transaction is already a distributed transaction. With SQL Server 2 ...Show All

  hi could you perhaps give me some information about this. How about restricting access to the web services by only allowing access from the local subnet i.e. if your network addresses are on the 10.0.0.* subnet, then only allow access from that subnet.

• Software Development for Windows Vista Communication between 2 different workflows

  I have a host application (a windows service) and 2 different types of state machine workflows. The workflow1 executes a certain amount of workflow2 and waits for the workflows to return. To do this they need to communicate between each other. I thought workflow2 could send an event to workflow1, in order to tell him when he's finished. Everytime a workflow2 returns it send this event to workflow1, so workflow1 can check if the started workflows are all finished. But how can I send events from one workflow to another Any ideas, which dont use wcf Thanks You can accomplish this by having a local ser ...Show All
