• Kumar Venkat Info on support for other platforms?

  Hi, I know that as of right now MS is only planning on supporting the browsers that are currently supported in the CTP, and I've read on a developer's blog that MS will be relying on partners to implement support for other platforms. Is there any of this work with partners underway Is there anything else that I'm missing I'm giving a presentation on WPF(/E) to some execs at my company, and I'd like to be able to mention something about support on other platforms because I know this will be a con when compared to Flash.

• GiriKrishna Help with Hands on Labs

  Hello, Over the last days I've started to experiment with Workflow Foundation, but I've had some problems. I find that when I want to create a local variable in a "HandleExternalEvent" object, it won't let me do it. I explain, in Lab05 for example, it asks you to insert a HandleExternalEvent object to handle the user's vote, and once you've changed the interface type and the event name, the manual tells you to " type the value votingArgs into the (Parameter) e field, this will create a local variable named votingArgs within the workflow". I do that and once I click somewhere else or I hit Enter, the word "votingArgs" disappears from the (parameter)e field, and the variable isn't created. The same thin ...Show All

• PhrankBooth Why graph fails to open after disconnecting pins

  Hi, i'm new in dShow, building a graph to capture video. I build graph with no problem but i want all filters to disconnect when i want. Before disconnecting all i save graph file (as connected.grf) then watch it, it has no problem; and after disconnecting filters save again(as disconnected.grf) when i try to open, it fails and it is surprising that connected.grf is 14 KB and disconnected.grf is only 2 KB. Also i can not reconnect filters again. HRESULT DisconnectAll() { HRESULT hr; DisconnectFilter(pFilter, PINDIR_OUTPUT); if(hr != S_OK) return; DisconnectFilter(pFilter, PINDIR_OUTPUT); DisconnectFilter(pFilter, PINDIR_OUTPUT); //And so on } HRESULT DisconnectFilter(IBaseFilter *pFilter, PIN_DIRECTION pinD ...Show All

• Mark Rodenhauser Object Collection Editor comes up disabled for Dictionary parameter

  I am using a CallExternalMethod activity in my workflow. I have a interface defined one of whose methods takes a Dictionary<string, object> as one of the input parameters.

• Vaish Which Atrributes? WCF & WF

  I am new and trying to grasp the proper design of interfaces for WF and interaction with WCF. It seems that interfaces need a structure like this for WCF: [ ServiceContract ()] public interface IService1 { [ OperationContract ] string MyOperation1( string myValue); [ OperationContract ] string MyOperation2( DataContract1 dataContractValue); } Yet, WF needs something like this: [ ExternalDataExchange ] public interface IService1 { void RaiseMyOperation1( string myValue); event EventHandler < MyOperationEventArgs > MyOperationEvent2; } How are these two supposed to be combined/ work together (yes - its a weird example, but even ...Show All

• GOH Omnipuff XPS and StartDoc

  I was trying my application on the latest Beta 2 release of Vista and found some weird features when writing out to XPS. In my application the user has the option of going into a print layout window. This layout window allows the user to place the desired application related objects on pages for printing. When the user goes into the dialog, I go create a printerDC based on the default printer and hang on to that DC until the user closes the layout window or changes to a different printer. While in this dialog, the user can change how the objects are layed out and print at any time. Inside I call startDoc with just the application name and when saving to an XPS the first time, the XPS file is generated successfully. If I write to a di ...Show All
