• Software Development for Windows Vista Trouble with the ManualScheduler service and delays

  Hi, so I have this workflow I've been working on for a few months. It's made of a few parralel branches (5), which look like this : picture The whole thing is hosted in an ASP.NET webservice (in its global.asax file). Along with the ManualScheduler service (with UseActiveTimers on), I'm running a persistence, tracking and data exchange service. And while I thought I did everything right (according to other posts here), expired delays still don't cause the workflow to fire up, so I always have to wait for the runtime to do something (ie : instaciate another workflow, send an event to a workflow, etc...) before anything happens... (this, I assume is what it is supposed to do without UseActiveTimers activated). I really hope ...Show All

• SQL Server ODBC Driver for SQLServer Everywhere/Compact from Access

  So far I've been unable to connect to a test SQLServer Everywhere/Compact database with MS Access. I installed the new SQLServer 2005 Native Client to no avail. Has anyone done this If you read the last post I made, it's pretty clear that I have Compact Edition 3.1 RC1 Beta. I haven't ever installed the Mobile Edition. After installing CE, most references (like the installation directory) reflect the previous name (Everywhere). I really want to link to a Compact Edition database through ODBC (as it happens, in Access). I can connect to it fine in VS 2005 VB.NET, so I don't think it's a lack of understanding. Thanks, any help will be appreciated. ...Show All

• Software Development for Windows Vista Conceptual problem - Force developer to implement a method

  Dear all, I am building my own Activity, a very simple one. I would like to have something like this: protected override ActivityExecutionStatus Execute(ActivityExecutionContext context) { string[] res = a(); return ActivityExecutionStatus.Closed; } My a() function is define somewhere in my activity but is forced to be implemented by someone who uses my activity.

• SQL Server Disable excel rendering from export button

  I have around 7 subreports in one main report. The data displays fine as required but when I try to export it to excell format it gives me an error saying that "Subreports within table/martix cells are ignored" . I know this is a known error and Microsoft would be releasing a fix for it in future releases(I hope in SP2 :-)). As per our requirement we have to store each report in excell format in our DB. Because of this problem we came to a conclusion to hide the excell format from the export button so that the user can select PDF insted of Excel. My question is : How do I disable the Excel format on the export button. There are 2 ways you could do this. First is to get rid of (rename) the rendering DLL file. ...Show All
