• Software Development for Windows Vista Composite activity design question

  I'm currently working on a design that would utilize a composite activity that contains an InvokeMethodActivity and an EventSinkActivity. The purpose of the composite activity is to encapsulate the sending of a message to a queue and then to await a response on a separate queue. This composite activity will represent the base class for many higher-level activities that will operate in this manner. Therefore, a workflow will be comprised of many of these types of activities. In the examples that I've seen for this pattern (InvokeMethod / EventSink), the event sink uses a service implementation that lives in the host process. In my case where ...Show All

• Visual Studio Express Editions Is there a "Setup" project available in Express editions?

  Maybe a dumb question, but I have Visual C# Express 2005 Beta 2 installed on my computer but it seems like it doesn't have a Setup kind of project. Isn't it available in Express editions How else, except for the Publish feature (which doesn't work as well), can I deploy my applications Resorting to 3rd party software doesn't sound too good to me. Is it something wrong with my installation It would be a pity not to include in VS 2005 such a tool. Hi A.L. Forgot to answer your other question: Setup projects are available in in the VSTS SKU. -Patrick ...Show All

• Visual Studio ReportViewer control - protected memory error when printing

  Hello, When me or my users try to print from the Windows Forms ReportViewer control to a specific printer (using PCL), the following error appears in the ReportViewerControl client area: Attempted to read or write protected memory.

The error appears after choosing the printer to print to and selecting "Print" from the dialog. The "Printng page x of <reportname>" window never appears. Does anyone know of this or a similar problem occuring elsewhere or if there are any down ...Show All

• SQL Server Execute phase Memory Error

  Hi, I have a data flow component that retrieves records from a table.  There is about 3 million records.  I do sorts on the records, then use a merge join transformation to join that sorted data with the dimension data.  However, when I pump 10,000 records through this transformation it works fine. When I try 3 million I get this error: DTS.Pipeline: Thread "WorkThread1" has exited with error code 0x8007000E.  I think this is a memory error. I have 1000 MB of memory 30 GB of hard drive space.  I am also running this on a virtual server. Option 1: Don't use merge join transformations and use Lookup's instead Opt ...Show All

• .NET Development Pondering over web services

  Hay all, I have been working with .net for over 3 years now, and have developed 2 enterprise level web applications. I have been coming across stuff over WWW where an asmx has been deployed and then examined using WSDL standards in order to find what are the methods, objects and their details. Wonderful, but what worries me as a developer is, am I on the wrong track or what I have been working on commercial, enterprise level softwares whose utilization in terms of data, speed, and users were complex. The web services I developed and used there were to make the data available and I did not bother to go through what were the methods and ...Show All

• .NET Development Any way to find the number of subscribers to an event using reflection?

  As the topic says, I need to find out how many subscribers there are to an event, given only an object and the event's name.  And, that event is owned by another class (currently limited to my own code, in my own assembly, but I can't expect that in the future).  My previous solution was to modifty the add/remove accessors, and expose a field that counted the adds/removes.  That was ugly. Ok, ok, I know.  Just the mere idea that I have to do this, is just plain bad.  None-the-less, I have no other ideas on how to avoid the problem I'm trying to fix.  (I'm currently building an AJAX [ooo, buzzword!] layer for AS ...Show All

• Windows Forms How to embed child datagrid into its parent in windows forms
