• Aditya Kirloskar Linker problems with VStudio 2005 and DirectShow

  Hello all, I'm currently doing some porting of projects from Visual Studio v6.0 to Visual Studio 2005. A number of these projects are filters that use the DirectShow API, which is installed on the computer as part of the DirectX v8 SDK. While VS2005 is able to update the project files etc. all right, when I try to create the filters, I get linker errors related to the DirectShow library, strmbase.lib. Currently I am using a version of strmbase.lib that was built using Visual Studio 6, and using the project/workspace files that comes included with the SDK. An example of the set of linker errors I get are as follows: Creating library .\Release/AudioResample.lib and object .\Release/AudioResample.exp Aud ...Show All

• IceAngel89 Event raising in workflow ?

  Hi Can my workflow have some events that I will handle in my application [for example windows forms code] I have application that should run in infinite while loop and stop for one hour after each succesful execution. So I would make while with with true condition and on the and of sequence I'd put Delay activity. But how do I know what's going on in my workflow if it never ends It will finally be used in Windows Service so it should be running every our do what it has to do and than go idle... But for now I'd like it to communicate with me by some messages. So if certain conditions happen I'd like to have an event raised.

• Sahus Making a GUI subservient to the WF

  I've got a situation where I am attempting to write a state machine workflow. This workflow responds to events on two data exchanges: 1 for network messages being sent from a central back-end location, and 1 for events sent from the GUI such as a submit button being pushed. I've got the 2 exchanges set up just fine. The other part of this is where I'm having difficulty finding a best practice. I want the Workflow to tell the UI which pieces of the UI should be enabled or disabled based on a rule set that I will probably store in a policy. For example, when the state changes, I want the policy (which reads variables from some dependency properties that are set by incoming events) to then fire off events such as DisableSubmitButton that will ...Show All

• Michael Herman - Parallelspace WF State Machine and ASP.Net Interaction

  Hi, I'm looking at hooking up an ASP.Net application to a State Machine Workflow. I currently have one running beside a windows form. In my current windows forms solution I use the "workflowRuntime_WorkflowIdled" event on the form to check what state the workflow is in and update my form respectively. I'd like to do something similar in ASP.Net but have a suspicion that the "workflowRuntime_WorkflowIdled" event will not work in ASP.Net. I'm not sure about this as I dont understand how threading would work in ASP.Net with the workflow. Would events raised by a workflow instance (such as workflowRuntime_WorkflowIdled") be caught by the ASP.Net process I think not as the page may be processed and served back to ...Show All

• AndyPham redistribution of SDK components

  What are the legal requirements for redistribution of components like mt.exe We'd like to redistribute mt.exe so our customers can apply manifests to their applications. However, I'd prefer to not require our customers to download the entire and Windows SDK just to do this. Does the license agreement allow me to do this It isn't entirely clear. Thanks, Noel Adorno National Instruments Hi Noel: You are not allowed to redistribute the individual components of the SDK unless they are explicitly listed in the redist.txt, that is installed on your computer by the SDK (in the license folder). MT.exe is not listed there, and is not redistributable. Using our Web install, your users can go to ...Show All

• AlexBB Mapping channels enumerated from IAudioEndpointVolume

  What is the rule for mapping the channel numbers returned by GetChannelCount to the front left channel, front right channel, center, side left, side right, etc IAudioEndpointVolume has a member function to set the volume of a specific channel. It will be nice to know exactly which audio channel gets modified, without opening sndvol. Thanks, IIRC, the channels are indexed by the bit position of the available channel mask in the mix format (the lowest enabled bit is channel 0, the next lowest enabled bit is channel 1, etc). Hmmh, Vista seems to map the surround channels incorrectly in a USB 5.1 surround audio device. The USB audio class channel config specifies the c ...Show All
