    - XOML files In WF Visual Designers On top of what Kushal said I was also wondering what other background processes are running. If you already have RTM of .NET 3.0 then what may interest us is the background processes that are running that may be blocking our performance so that we can try replicating your problem and increase our performance. Thanks Elif Tag: Integrity level

    - State Workflow runs a bit and then, well nothing... (and its driving me nuts!) yes, I guess that makes sense, which makes me think (yet again!) that I dont really want to use the manualscheduler. I want emails to be sent, things to timeout etc, even if no one is running anything on the web site, so calling RunWorkflow to move to the next idle state isnt really going to work for me (and for many people with long running workflows) I have the workflow hosted in global.asax. is there any workaround to get the IIS and ASP.NET friendliness of the manual scheduler, but to have things moved on regularly, perhaps on a timer is that possible in global.asax Tag: Integrity level

    - Custom SetStateActivity to log state changes + reason Ok, what I did was to hook up an event handler to all of the Executing events of all of teh SetStateActivities in my workflow recursively. Then I can get the owning stateactivity of the sender, its TargetStateName and I also logs its Description as I put the reason for the transition into that. Code Snippet private void hookUpSetStateAuditEventHandler( CompositeActivity rootActivity) { // must go down thru the activities hierarchy and hook up an event handler to the foreach ( Activity act in rootActivity.Activities) { if (act is SetStateActivity ) act.Executing += new EventHandler < ActivityExecutionStatusChangedEventArgs >(setstateActivity_Executing); else if (act is CompositeActivity ) hookUpSetStateAuditEventHandler(( CompositeActivity )act); } } I've no idea if it actually works as I cant get my workflow to run at all right now!!

    - live video overlay at 20% cpu on primary monitor, 100% cpu on TV out?? Hey everyone, I am doing overlays onto a live TV broadcast and have written a custom VMR Allocator-presenter to do the job. I render my overlay ( bitmaps and/or text ) onto a DIrectDraw surface and blit it over the video within the 'PresentImage' routine. Recently I tested my program with full screen playback on the TV output from our units ( they only have basic onboard video cards) and the CPU usage jumped to 100% with choppy playback. With full screen on the primary monitor I get CPU usage of 20% with great playback even with overlays. I have also tried playing the capture feed in a window, and as soon as any part of the window hits the second monitor the CPU again jumps to 100%. I ran the DirectX Diagnostics tools to check the capabilities of the second monitor, and found that ‘AGP Texture Acceleration’ is unsupported. This is the only difference I can find between the two monitors. Could this be the cause of the problem I have also tried setting the default monitor to the secondary monitor through the IVMRMonitorConfig interface and performance didn’t improve. Finally I get good performance on the second monitor when I remove my all my code used to perform overlays and call the standard VMR presentation routine, which may suggest that the video card does not like when I use the DirectDraw surfaces to perform overlays on the secondary monitor. Has anybody here experience anything like this before I was thinking that perhaps the DirectDraw surfaces may not be handled by hardware for TV output, although I hope this is not the case. Any suggestions would be greatly appreciated.I hope this makes sense, if anyone would like more detail juat let me know. (and hello to Michel R, you will recognise this question im sure!)

    - Vista and Symantec Ghost 8.x Thanks for the response. I was not aware that there were any NTFS changes in Vista. (At least not yet.) And its still reporting as NTFS version 3.1 in 5270, for what its worth. Agreed that obviously there are changes in the boot loader. And perhaps one day Ghost will do something to take this into account, if taking this into account even ends up being required. But as described, Ghost 8.x actually does work; restoring a disk image without -FDSP fails (as does a partition image), but restoring the same disk image with -FDSP works. So the disk signature appears to be a factor, but still the question of whether there is something that could be done to "prepare" Vista for the fact that its going to be restored to a different (zeroed, or at least different) disk signature. Since Ghost has had the -FDSP and -FDSZ for quite some time, yet I've never found the occasion to need or use them, my question was perhaps whether someone who understands more specifically what this would affect and/or what Vista is going to require to successfully find the boot partition (that is apparently being affected by -FDSP, based on the results) might be able to explain what these clues are more specifically pointing to. Or, someone who is successfully using Ghost 8.x for partition backups/restores of Vista 5270 confirming no issue, such that I'll know there is some other factor I need to be chasing down. -Alan Tag: Integrity level

    - 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 Thanks for the reply, Sonali. What I need is cancelling of a non-composite activity from inside that activity. I do not wish for the workflow instance to terminate/complete; one could say I wish actually to "skip" the activity (still better, I wish it to execute an alternative code - not the normal "execute" code - and I need to know via an event when this happens). All samples/concepts I've seen so far deal with cancelling of a composite activity, where the composite actively initiates the canceling of its own children. One may define CancellationHandlers only for a composite activity. My problem lies the other way round: The child of a composite activity (or a "child" of the root activity) receives the command to "cancel" itself. I would like to perform alternative code and to have the activity transit into the canceling state + firing the StatusChange event. If this is my workflow definition, the red activities should be the ones which may have to perform a "Cancel" command. + rootActivity + some activity + a composite activity + a child activity + my non-composite activity + another child activity + some other activity + my non-composite activity + yet another activity I'd just like to know if there is some concept of canceling a non-composite activity from inside that activity (not via its parent) and getting the transitions + events right without much additional work.

Hi, All

Do you know how to start an elevated process with medium integrity level from a low integrity level process using API

More specificly, which SID value to use, I saw an hard-coded example using "S-1-16-4096" for Low integrity SID, but what's the value for medium level I cannot find it from June CTP's SDK and document.

Thanks!

Re: Integrity level

Nico9.1

I think you cannot start a MediumIL process directly from a LowIL one (and more generally, an elevated process from a least-privileged one); you should use a MediumIL (or HighIL or SystemIL) broker process.
If it was possible it would have security risks because, for example, malware could elevate silently to go outside IE7's protected mode ...

LowIL : S-1-16-4096
MediumIL : S-1-16-8192
HighIL : S-1-16-12288
SystemIL : S-1-16-16384
