• JDaniel Speed difference between GraphEdit and custom application

  Hi, wonder if anyone has encountered this problem. I have a custom transformation filter, which runs basic thresholding computer vision algorithms. In GraphEdit, it uses 47% of CPU capacity and runs very fast, but when loaded into my custom application, uses 99% of CPU capacity and runs very slow. I use an Acer Travelmate 8104 2GHz Centrino. The obvious culprit is the application, which I initially wrote in C# using DirectShowLib from sourcef ...Show All

  Using Feb CTP. I defined a Policy which reads its rules from XML. After Execution of the Policy it correctly maps the result of the ThenAction of the rules to properties defined in the workflows.

I rather want to check the results after policy execution and loo ...Show All

Hi, The workflow designer is not part of the VSTA IDE, but if you have a host application that has implemented VSTA you may be able to use VSTS to create VSTA add-ins. ...Show All

• Ms_d Various comments on Default application projects

  I've been playing a bit with beta 1 and beta 1.2 and there are a few things I'm not very comfortable with in the default code generated when you create a new Workflow project (C#). For example, the default exe projects (e.g. sequential workflow console application) have absolutely no error handling at all. Now, I'm assuming that many people might just fail to notice this and either use the generated code in Program.Main as is or with little mod ...Show All
