• NedNed Recorder order

  I'm noticing that adding external recorders (via USB) shuffles the order around. So it is not the case that the first recorder known to the system is 0 and additional recorders get incremented numbers. How is this order determined Alphabetically by model / manufacturer This might be important, because it a GUI might give exceptional treatment to an internal recorder. Maybe that is a better question to ask / thing to query for - is that possible (internal vs external) Hello foobarX! It is not currently possible to query for internal vs external recorders. The MsftDiscMaster2 object simply enumerate all the devices in the system that expose the CDROM device interface. We just wrap a public ...Show All

  For the life of me I can't seem to get [ToolboxBitmap(typeof(ActivityTest), "Resources.IconName.png")] to show the icon in the workflow am I missing some other line of code somewhere or is there a know bug I’ve tried everything from checking the format of the .png to writing whole new Activities. Any help would be greatly appreciated yep thats cracked it Cheers! I've looked at the SendEmailActivity which is part of the MS workflow samples. The c# version shows the icon, but the vb version does not. They've forgotten to set the buildaction of the png file in the vb project to Embedded Resource. So i changed it. But the workflow of the sample project doesn't show the icon. What can be the reason ...Show All

• DCMonkey MsiRMFilesInUse dialog using VS2005 Installation Project & Orca

  I have a pretty simple installation project created using VS 2005 installation project, and am having several issues complying with some of the requirements. So far, my most frustrating problem is test case 25(v1.1.001 of Certified for Windows Vista Test Cases). There is no MriRMFilesInUse dialog available through visual studio, so my understanding is that I have to create my own manually using Orca. After digging and digging, I was able to find a very old, prerelease rss feed of what the tables needed to have in them for the dialog: http://blogs.msdn.com/windows_installer_team/archive/2005/11/03/488945.aspx Based on this, I added all those fields and values (with a couple minor variations such as the binary banner filename (i just u ...Show All

• vtortola Using Windows SDK (With the Glass Effect)

  I have Windows XP and I downloaded Windows SDK for developing apps that are compatible with Vista, is it possible to make an app on XP with the glass effect or do I have to use Vista to create an app with the glass effect Hi Sniper, The Aero glass effect is something that is unique to Windows Vista else we would have seen such apps on XP itself by now. However you can get a "little" close to that by using the Opacity property of Windows Forms and the effect can be seen on XP as well... even on Windows 2000 for that matter. A bit of smart and careful super-imposing and you should be able to get a little closer. Though you cant still compare that with the now famous Glass effect of Windows Vista. Regards, Amol. ...Show All

• chazparks IActivityEventListener custom activity

  I have created a custom activity implementing IActivityEventListener interface. Then a EventArgs derived class which delivers the queue message. Then, from host application I send a queue item to the workflow calling the workflowinstance's EnqueueItem method : how can I intercept the message in the OnEvent method instead of Execute method I have also tried to create the custom activity as IEventActivity to be hosted inside an EventDrivent one, but the effect is still the same: only Execute method is called when message is received. Thank you very much in advance. Exposing the custom activity also as IEventActivity: i.e. public partial class MyEventActivity: Activity, IEventActivity, ...Show All

• Greenstrike How to cancel a sequential workflow with cleanup in advance

  Hello, I want to cancel a sequential workflow, but doing some cleanup in advance. The terminateActivity just aborts the workflow and I 'll have to do some cleaning just before getting to the terminateactivity all the time(because it does not go into faulthandler or cancellation handler). But the cleanup procedure is always the same. Furthermore I have to do this very often in serveral branches in the workflow erverytime I want to abort the workflow, so this is no solution. If I raise an exception somewhere in the workflow I 'll get to the FaultHandler. The activities in there are then being executed and then the workflow continues. But it has to be aborted! So I could throw some exception again inside the faulthandler...ugly! But I nee ...Show All

• kid_kaneda Setting volume levels with IAudioVolumeLevel

  Hello, I've been trying to set the level of a particular part by using the IAudioVolumeLevel interface of the API. I can Activate a valid instance of the interface, and when I call GetLevelRange on it, I get a min value of -34.5, a max value of 12, and a step value of 1.5. However if I loop through the valid step values and set them with SetLevelUniform, while comparing the value of the volume level slider in the Control Panel (which goes from 1-100), I get unexpected results. The number on the slider (and volume from the speaker) remains at 0 for the first 8 iterations of the loop until I get to a level of -24 for the SetLevelUniform call, at which point the slider value moves to 1, where it remains until the 8th iteration in the loop ...Show All

• r3zonance Hosting a workflow within an XBAP - is this possible?

  Well the subject title says it all really. Is it possible to host and run a workflow instance from within a XAML browser application Are there any security issues I need to be aware of and has anybody got an example of this On the face of it I can't see why I couldn't do this but I'm still learning workflow and presently don't know much about XBAPs either. My idea stems around the possibility of building my own workflow designer thats based around my own set of Domain specific activities. I wanted to run that designer from within an XBAP so that it would allow the user to design, compile and subsequently run a workflow. The activities within the workflow would be visual in nature so I would want to run the workflow from within the X ...Show All

• Mehmet Metin Altuntas Type Intialization Error for Custom State Activity

  Hi, We have Created our own custom State Activity called " WorkflowState" by deriving it from System.Workflow.Activities. StateActivity.

But when we come back later and open the Workflows using the Visual Studio Designer, we get the following error. Error Loading Workflow The type initializer for UTProduct.Web.Workflow.Activities.WorkflowState threw an exception. This behaviour is different on different machines.
