• Ben Tsui How to get WPF and WF work together?

  Hi, I got this two technologies to work together but only to a certain degree. As soon as I want to describe wpf components derived from my own type I'm having problems with namespace mapping. I'm getting following error messages: - If this type is from another assembly: "Unknown build error, ''clr-namespace:MyNamespace;Assembly=MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' mapping URI is not valid. Line 2 Position 13." - If this type is from the same assembly: "The "CompileWorkflowTask" task failed unexpectedly.

• LotusExigeS1 Listen Activity in state machine workflows

  Hi, Can we use listen activity in state machine workflows. Here is my case, where i need to use listen activity, (which i thouht it would be better) I have created state machine workflow for my web application and when web app raises some events, i have to change the state of my workflow from one state to another. In the workflow, I have an event, which executes sequence of 7 steps. When user clicks a button in my aspx page, i am raising the event and the event performs all these 7 steps. Its working fine! Now i got another requirement, that user can raise one more event (from other button, but the state remains the same), which is very similar to that of former, but it has one different step at #2 position of sequence. The rest of the seq ...Show All

• FA65 How to record from 'Wave' or 'Stereo Mix' in Vista?

  Hi all, I wrote the following question in other forum space but some MSFT guy told me to try this forum for my question. I hope I could get right answer as soon as possible here. On Windows XP or earlier, I could capture the audio stream to the speacker not from the external device (maybe endpoint device in Vista) like the microphone. In other words, D irectSoundCapture was able to capture from the selected recording device/source line in the Windows record control utility or mixerXXX APIs. And if "Wave Out Mix" or "Stereo Mix" or something similar was selected as recording source line, D irectSoundCapture was able to record the audio stream to the speacker. However, I could not find the way to do tha ...Show All

• jcavazos web services

  Hello, am I correct to understand that there is no .NET framework integration yet I am wondering what support for calling web services there will be in v1 release. The usage I am thinking for WPF/E is to have XAML+C# as a complete front-end, using no javascript, and talking to backend web services. Does this sound like a reasonable usage that will be well-supported and is a goal for the WPF/E initiative To me it does not look like the December CTP supports this. Thanks, Brad Williams Did you see http://www.nikhilk.net/WPFEAndScriptSharp.aspx Hi Brad: Depending on what you want to do, you can actually come quite close to this with the current CTP release.

• Philippe Cand WF Designer - How to display Activity Full Name

  Hi Dear, I would like to take a print screen of my WF Design to document my work but when the activity name is long then the WF Designer cuts the end of the name and replace it with dots (e.g., receiveCustomerOrder is displayed as receiveCustomer...). It would be nice if the WF designer allows adjusting the size of the Activity shapes (just like controls in a WinForm) but unfortunatly it does not. The shape size is fixed. Could you please advice on how to get the WF designer to display the Activity Full Name How can we resize the Activity shape (I hope that I wouldn't need custom activities for such simple feature) Thanks Karim This feature (ability to resize/auto-adjust Activity shape ...Show All

• mihe How to get child workflow instanceId after calling invokeworkflow

  Hi, I have one state machine workflow, in the start of the workflow, it will call InvokeWorkflow to invoke a sub workflow which is also a state machine workflow.
