• Anarchy Some basic questions about Extensibility

  I am primarily interested in writing some add-ins for my teams project in C#.  I wrote some add-ins years ago for Visual Basic 6 but dont remember much about it. I was hoping someone could answer the following questions: I am confused with the difference between EnvDTE and EnvDTE80.  I know that EnvDTE80 is the new object.  Does it contain everything I need for writing add-ins Meaning backwards compatibility Or is it an addition to EnvDTE and both must be used in a project   Is there a time when I only need to use EnvDTE80 or vice vera if so Same question relates to VsLangProj and VsLangProj2. I suppose its the numerical iteration that confuses me.  Usually when a new object is released it contains all ...Show All

• Pauly C MergedDictionaries problem

  Hi! Assume I have the following style in a file called myControlStyle.xaml: <ResourceDictionary> <Style TargetType="myControl"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="myControl"> ... <Border BorderBrush="{StaticResource myBorderBrush}"> ... </Border> ... </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> As you can see, it uses a brush called myBorderBrush.

• M. Nicholas Blend modes not supported in WPF?

  Are blend modes not supported in WPF With the recent release of WPF/E and the new CTP's for the Expression tools, my interest in WPF has rekindled.  However, after searching the Web and Newsgroups it seems that blend modes are not supported in the WPF.  I'm not quite sure what the rationale behind leaving this feature out of WPF was. (Purhaps time constraints )   I'm sure the developers on the WPF team know how to program support for blend modes.   It's pretty much well documented on the Web.   I've even written a few for a custom layering application I wrote for .Net 1.1. a year or so ago.   It's odd that they took the time to program support for filters such as drop shadow, blur, and reflection, but not ...Show All

• chunkai Is WPF right for my app?

  I am in the process of determining if WPF is right for my app. M y app requires that my main entry form look like a paper form for example a IRS 1040a. I can draw this form very easily on a Canvas, but because the canvas is position based, it doesn't resize with the screen, however I need to be able to resize the whole canvas based on screen size. I have tried the grid and stack panel but the wrapping and resizing doesn't work for what I want. I have to maintain the look of the form and maintain the aspect ratio as well. Any suggestions or where to look for examples would be greatly appreciated. rockowpb Thanks so much. The viewbox did the trick. Works great. Wow this is really good stuff. ...Show All

• Andrew Shearer Building expressions at runtime

  Hi all :) I've started experimenting with the whole expression tree stuff and it looks really interesting. I'm thinking of a way to let a user specify certain operations ( +, -, / , * for example) and build a function out of it which can be saved and used later on. I know I can do something like this: ParameterExpression p0 = Expression .Parameter( typeof ( float ), "x" ); ParameterExpression p1 = Expression .Parameter( typeof ( float ), "y" ); var e = Expression .Lambda< Func < float , float , float >>( Expression .Subtract(p0,p1), new ParameterExpression [] { p0, p1 }); Console .WriteLine(e.Compile()(3,4)); And this will print -1 as output. But how can I generalize this I wou ...Show All

• buzzbuba Client and service see different SessionId for a duplex contract?

  Hi, I have a simple WCF app using the NetTcp binding and a duplex contract.  I'm using InstanceContextMode.PerSession and the sessioning works fine.  What I don't understand is why I get different values for "SessionId" on the client and service side when using a duplex contract.  For a non-duplex contract the client and service are seeing identical "SessionId", which is what I would expect.  So why not also for a duplex contract   Thanks, Alan Client code:     String strSessionId =         CMyService_ClientSideProxy.InnerChannel.SessionId;     These return identical strings to strSessionId above:     CMyService_ClientSidePr ...Show All

• Adrian Slack Why is DTC Starting when Using System.Transactions with ObjectContext?

  This might be a question that applies to ADO .NET in general, but the only time that I've used System.Transactions and TransactionScope is with ADO .NET Orcas and so I've only seen this behavior in the scope of my exploration with ADO .NET Orcas. My appologies if this question is posted to the wrong forum. The DTC started when I instantiated a transaction scope and used an ADO .NET Orcas object context within that scope. Is the connection objected used by ADO .NET Orcas automatically promoted to a transaction that has to be managed by the DTC, or does the DTC simply pre-emptively start when a transaction scope is created regardless of whether the underlying resource requires the DTC Thanks, Carl.

• PiGuy Asynchronous LINQ???

  Given WCF's decent support for asynchronous server-side methods (going by the docs), is it likely that LINQ to SQL will support asynchronous query execution in the future Perhaps a BeginToSequence method, eg: IQueryable<Customer> customers = dataContext.Customers.Where (c => c.Name == "Jones"); IAsyncResult result = customers.BeginToSequence (Callback, null); It might be worth including such methods because for the end-programmer to add them could involve re-writing DLINQ. An alternative would be modifying the thread pool so as to be tolerant of blocked threads, thus allowing blocking methods to be used (at least in medium-load application servers) without problems. Obviously the thread count would rise, but this might b ...Show All

• Beast Forever Outlook 2003 Add-In being disabled

  I have seen several posts on this subject but I have yet to find one that answers the question about what is really going on. What I have found my my Add-In is that there are two scenarios that VSTO doesn't seem to be able to deal with. 1. Sending a file to a Mail Recipient using right click in explorer I really would have expected this to work and the Add-In would just have to catch that there is no UI and bypass that functionality. The result of this on my systems is that the next time Outlook is loaded the Add-In is on the disabled list. 2. ActiveSync loading part of Outlook and then not releasing it. I have yet to fully understand this but I assume it is similar to number 1 but slightly more annoying in the fact that eve ...Show All
