    - OutlookWorkflowWizard and interop assemblies I am using Office 2007. I was trying to compile the SDK sample for the OutlookWorkflowWizard but it would not compile because it could not find the: Microsoft.Office.Interop.Outlook namespace These I believe are a part of the Office Interop assemblies. However, I cannot install these because in order to do the install, it only looks to see if you have Office 2003 installed. Does anyone know of another way to get these assemblies on the machine Thanks. Tag: Window Media Player Gadget Issue

    - workflow foundation Installing WinFX A successful installation of .NET Framework 2.0 is the first thing we need to use Windows WF. You need to have the latest version, because older ones don't work with the latest bits. On http://msdn.microsoft.com/winfx/ , click Get the Beta . You need at least, the WinFX Runtime Components along with the Visual Studio 2005 Extensions for Windows WF. Of course, for the latest item you must have a running Visual Studio installation (Express editions won't work). These extensions to the integrated development environment (IDE) are necessary because, although it is possible to create the workflow in code, it makes easier to manage the XML and code-behing files Windows WF uses for its work. Downloading the entire Windows SDK to check other new technologies such asWindows Presentation or CommunicationFoundations is also suggested (formerly known as Avalon and Indigo, respectively). Why Workflows Until now, flowcharts and process schemes were done separately from code, just as a way to organize ideas before writing the actual code. But when the task was finished, the scheme remained just as documentation. Also, the capacity of older computers made impossible to retain all the information of a workflow in memory, and it was difficult to translate from an easy-readable format for human to machine code. Windows WF tries to solve all these problems, making workflow technology available to every single programmer that uses the .NET Framework, and thereby making it general enough to be used in different situations. That seems the natural step from the interoperability concepts in the Framework; if it can execute code written in a bunch of languages, then why not have a tool that translates a conceptual idea of how a work is to be done in real, compliable code Windows WF can be used for document management (for that special task it will be integrated into Office 12 ), business cycles, or page flow (by making use of ASP.NET). There are lots of reasons as to why a developer would choose writing a workflow instead of writing the code. First of all, for programmers, workflows are easier to understand than code, because workflows provide a visual representation of the process. Consequently, code becomes harder to maintain and adapt to new areas. For example, adding a step in the middle of a scheme because we need to have an additional agreement with the user because of newer laws can be real pain for coders, but an easy step for workflow users. In addition, Windows WF provides a way to extend existing workflows without need of recompiling, so general frameworks can be developed and then customized to fit in different areas. Basic Concepts Layers in Windows WF : The first one is the code that uses the workflow, because a workflow is not an application, but instead a set of actions that is executed asynchronously by the engine provided by Windows WF. That's the key to being able to use a workflow in such a variety of scenarios. The interface that allows communication between that engine and the executing process is called the Hosting Layer, which provides some extra services apart from Communication (send an receive events and data from and to the workflow), like Persistence (which allows saving the state of the workflow in a storage media to restore it later) or Tracking (so the actual code running the workflow can log the execution of it). Finally, we find the Runtime Layer, which actually executes the workflow and manages the core services. One different with the other two layers is that Runtime Layer is not extensible, while more services can be added to the Hosting Service. Apart from these layers, Windows WF comes with an integrated designer that by default integrates smoothly in Visual Studio 2005, but which can be used outside it, so any developer could add drag-and-drop support to its own application. Activities and the minimal units in Windows WF : Each activity receives some parameters from the developer, executes it actions, and then the flow is transferred to the next activity. Some examples are Code or IfElse activities. As developers, we can create new activities and use it in our own code or create an Activity Library for selling. We can get new activities at no cost on its official website www.windowsworkflow.net . There are two main kinds of workflows: 1. Sequential: Its actions are executed in some predefined order with a beginning and an end. Examples of sequential workflows may include installations. 2. State machines: These workflows don't have a path, but it's represented as a set of states and transitions between states. Examples are a web shop: you may need approval for mailing, the user could pay via credit card or with a cheque, and each user is in one state and may go to any order depending on previous questions.

    - Recommended way of cancelling a non-composite activity Just another thought: If the concept of canceling activities is build around "parent is responsible / initiates the canceling of its children" could I get the parent's AEC from inside the child activity I've tried childAEC.ExecutionContextManager.GetExecutionContext(this.Parent); from inside the child but got a null context. With a valid parent context I could trigger the scheduler to enqueue the cancel command for the child. Aleydis Tag: Window Media Player Gadget Issue

    - Problems with Properties.Settings under Vista. The thing is that it does read and write the settings correctly when using the settings dialog and the preview function. So would there be something special Vista does when the SS actually runs When you say that you guess that Vista won't allow reading from any storage, would that mean thatit wouldn't be able to read an ini file if I tried that as an work around. Would registry be an option Or would that probably also then be protected. What I don't understand is why it partially works. Tag: Window Media Player Gadget Issue

    - SqlPersistenceWorkflowInstanceDescription Help! Joao Ricardo Pereira wrote: For each state I have a control that displays in a gridview the list of workflows that are waiting for that step. When the user selects the instance, it redirects to another control that asks for some information in order to submit and call the event referenced by the HandleExternalActivity in the WF. The problem is that there are more than one person processing each step, so I need to lock each instance to the user when they begin the attendance. I've done some research and found that the Persistence Service provides a "Locking Workflow State Information" method that I found very interesting. The workflow will not be locked until after the event that the handle external event activity subscribes to is raised, not when the user selects the instance. It will only stay locked until the workflow becomes idle and is persisted again, which is normally a fairly short period of time. It might be simpler to just handle either the WorkflowOwnershipException or an EventDeliveryException and give the user a message like “Instance already being process for step ‘foo’”. Joao Ricardo Pereira wrote: Even so, there is a method Find(), that I can't figured it out... SqlPersistenceWorkflowInstanceDescription tree = s.Find(Predicate<SqlPersistenceWorkflowInstanceDescription> match); Predicate is a generic delegate used to compare items in a List<T> to find a particular item, for more information see http://msdn2.microsoft.com/en-us/library/bfcke1bz(vs.80).aspx . Below is an example of how to use the Find method with the list returned from GetWorkflows, orderId is the instance id that is being looked for : List < SqlTrackingWorkflowInstance > queriedWorkflows = ( List < SqlTrackingWorkflowInstance >)sqlTrackingQuery.GetWorkflows( new SqlTrackingQueryOptions ()); SqlTrackingWorkflowInstance sqlTrackingWorkflowInstance = queriedWorkflows.Find( delegate ( SqlTrackingWorkflowInstance workflowInstance) { return workflowInstance.WorkflowInstanceId == new Guid (orderId); }); Tag: Window Media Player Gadget Issue

    - Worked on one computer now SqlWorkflowPersistenceService fails to persist on new computer. The stored proc you want to watch is InsertInstanceState . It will be fired by the persistence service whenever a persistence point is reached in your workflow (either an event wait or end of an activity marked with PersistOnClose like the TransactionScopeActivity .) InsertWorkflowInstance is a stored procedure used by the SqlTrackingService . The table you want to watch for persisting workflows is called InstanceState . The WorkflowInstance table is for tracking only. Are there records in InstanceState As you watch the SQL Profiler you should see a call to InsertInstanceState which will have the @state parameter full (not 0x) and the @status parameter will be 0. Then sometime later you will see a call with @state set to 0x and the @status parameter will either be 1 once your workflow has completed (reached final state.) Are you seeing any calls to InsertInstanceState One other thing to note (added after my initial reply): You probably need to add the SharedConnectionWorkflowCommitWorkBatchService to the runtime. You can see the configuration that I'm working with here . This is important if you are using a database instance on a remote machine to avoid DTC cost and configuration issues. I'm not sure that you can even use a remote SQL Server for the SQL persistence and tracking services without it based on this post . Tag: Window Media Player Gadget Issue

    - Windowless activated ActiveX ported from VC6 not painting under VC8. I have an ActiveX control from VC6 which was working fine. It supports windowless activation. This control is placed on a CDialog based class. I used the wizard to create a wrapper class and include an instance of it as a member of said dialog. The control is created and it actually gets click events if I click where I think it should be so it is just not painting correctly. Then I found that the OnPaint in the CDialog derived class it lives on, was overridden and it is not calling the base. There is a comment from VC6 class wizard to not call the base CDialog :: OnPaint. I eventually also found out that CDialog :: OnPaint is where it checks for control containers and relays paint messages to them. Calling the base CDialog :: OnPaint gets me closer, but the control now covers the entire dialog. The OnDraw within the control calls ::GetClipBox on the ATL_DRAWINFO::hdcDraw DC. This returns a rect which is the entire area of the dialog. The prcBounds of the same struct shows the correct control rect. So my questions: 1) Should I now be calling the base CDialog :: OnPaint if it is overridden in the derived class This is a change from VC6 to VC8 Or is there another way to have MFC trigger the OnDraw for the windowless activated control 2) Why is GetClipBox returning the full dialog rect Thank you very much for any assitance.... Going on three days now with this. Tag: Window Media Player Gadget Issue

    - Calculate the width of a space? So I have a string, like "The cow jumped over the moon." I see how through the GlyphTypeface that I can measure the width of each individual character. What works great! What I can't figure out how to do is get the width of the space between the words. Let's say I have the following method: Code Snippet public double CalculateWidthWithSpaceAtTheEnd() { double width = 0; ushort glyphIndex = 0; Geometry geo = null; foreach (char ch in Text) { glyphIndex = Typeface.CharacterToGlyphMap[ch]; geo = Typeface.GetGlyphOutline(glyphIndex, EmSize, 10); width += geo.Bounds.Width; } char spaceChar = ' '; glyphIndex = Typeface.CharacterToGlyphMap[spaceChar]; geo = Typeface.GetGlyphOutline(glyphIndex, EmSize, 10); width += geo.Bounds.Width; return width; } I would think what that would do is add up all the widths of the individual characters in a string, then get the width for the space for that font, size, and hinting, and add that to the total width, giving me the width of a word with a space at the end. However, the width in the bottom portion comes out as -Infinity...which obviously isn't really getting me what I want. Any clue Or, does anyone know of a way to calculate the actual width of a string (like "The cow jumped over the moon.") without having to go through the task of measuring each individual character Any help would be appreciated.

    - Which folder for HTMLHelp .chm files in Vista? I have an application which uses WinHelp32 which is deprecated in Vista. We had been using HTMLHelp, but this no longer functions over networks and has inadequate popups. I am aware of workarounds for the HTMLHelp network issue, but do not find my customers eager to implement them. My current thoughts are that for Vista we should write our own popup help code (this is almost done for the limited functionality we require) and use HTMLHelp for the main pages. For network users (where the .chm file will be unusable by default), we should copy it to a local drive the first time a client starts the program. My question, therefore, is what is the best folder to copy the help file to ie what folder is guaranteed to be writable by a limited user and guaranteed to be local Tag: Window Media Player Gadget Issue

Hi,

Use the i-mate SideShow Debugger that I wrote to show you how the Windows Media Player gadget works.

http://www.clubimate.com/t-WINGADRV.aspx

You will be able to see the raw content that is passed to the device and also the events that are passed to and from the gadget to the device.

Hi,

The Windows Media Player gadget does not actually transfer the music to the device; it simply controls playback of the music using the PC's audio hardware. All of the music playback is happening on Windows Vista, and being output using the standard audio output mechanisms for that PC.

To show the elapsed time and playback state, we do refresh the same content ID every second with the updated information when playing a track.

Hi, Dan

Thanks for your answer. And I have another question, is that the Windows Media Player gadget contorl the playback of the music through posting application events If so, and how can I know the exact event ID

Ender

Re: Window Media Player Gadget Issue

Dan Polivy - MSFT

Ender,

Yes, the gadget uses Application Events to control playback. The events are the standard SCF defined Application Events, listed here: http://msdn2.microsoft.com/en-us/library/ms744205.aspx. Different events are used in different scenarios; for example, selecting items off of a menu causes the Menu Action event to fire, selecting off the context menu fires a Context Menu Action, while any other navigation causes a Navigation Event.
