• Software Development for Windows Vista State Workflow - How can I do that?

  Hi, I have a question regarding State Machine Workflow implementation. My situation is like this: I have several states like IssueCreated, IssueAssigned etc and let's say that IssueCreated state has two EvenDriven activities. The first is ussual listening to an external event and setting to IssueAssigned status and the second is a Delay for an hour and sending an email after. IssueAssigned is listening to another external event - IssueOpen. When IssueCreated recieves an external event it sets the workflow to IssueAssigned state and delay is started. I need the next thing - if IssueAssigned state recieves its external event IssueOpen it should move the workflow to the next state (that's ok) and should cancel delaying and sending an ...Show All

• Visual Studio 2008 (Pre-release) Reloading DLinq created objects

  Hi! I am using MS SQL 2005 Express db. With SqlMetal I generated appropriate database table classes. I will try to be abstract: I have an A and B objects, where A has a reference to B object. DLinq generates two properties: 1) reference to B object 2) reference to B object identifier (B_ID) which in my case is value type The problem is that if I create A object and I assign valid B_ID property and submit changes to DB, I can not get the B reference (object). If I restart everything, I see my added B_ID value and then I can get the B object through B property. Any clues Thanks, Edijs ...Show All

• Visual Basic IP Camera HowTo?

  Hello everyone, I've just installed an IP Camera in our network and started to fool around with it. The software supplied by the camera itself is written in Delphi and pretty much doesn't do much. I was wondering if there was a way to connect to this Camera from the network with VB I googled around and didn't find much on connecting to this camera (or any ipcamera that I could understand). All I know is that the camera runs a sort of webserver on port 8888 that when I connect to asks for a username and password, afterwards it forwards me to a page where I can watch a stream of jpeg images (mjpeg) I think. If anyone can help me or point me in the right direction on how I can connect to this device (or similar device) and show the i ...Show All

• Visual C# COM object interfereing with a CheckBoxList?

  I apologize if this is the wrong area, but I couldn't find anything else that fits the subject quite right... I've got a com object ( IE ) running and grabbing information, however when I try to populate a CheckboxList control, it simply refuses to fill the control with any data. Is there some weird interaction between the two I am unaware of So basically, an event fires,and then data is processed, here's a quick snippet... CheckBoxList checkBox; checkBox = new CheckBoxList(); // Get the data, and now... foreach(string dataItem in myData) { checkBox.Items.Add(dataItem); } After this is through I would expect my CheckBoxList to be populated, but it remains blank. Any ideas on why this might happen Thanks! ...Show All

• Visual Studio 2008 (Pre-release) Combining Multiple 3D Meshes into One Giant Mesh

  If I have ‘n’ number of 3D objects positioned in space, is it possible for us to combine all these objects into one larger object (while maintaining their position in space) Scenario: - 20 cube meshes - Each with the same material - Each positioned in different locations in 3D space I am unfamiliar with WPF’s backend but does it have 20 meshes it draws then fill in with 20 materials 20 unique "actions" What I’m trying to achieve is to programmatically combine all the meshes into one giant mesh then draw with one material. 1 unique "action" hence (possibly) improving performance. Any suggestions Heck, will this even result in a performance gain Thanks. ...Show All

• Visual Studio Team System Problem file name and line number not setted

  Hello, I am facing a curious problem and I am unable to put key words on it. I coded some CustomRules and thanks to this forum loaded them into Vs Team developper. The problem is that when I run code analysis some of my rules raise warning and error but the file name and line number is not set, so I am not able to click the message in VS ErrorList to open the right file to the right line number.

• Commerce Server Commerce Server Web site as a Visual Studio file system Web site

  Hi, I was reading the MSDN documentation on creation of a Commerce Server Web site and it states that a Commerce Server site must be created as an IIS web site and not a file system site in VS 2005. Link to the same : http://msdn2.microsoft.com/en-us/library/aa545520.aspx Can someone explain why a Commerce Server Web site cannot be created as a Visual Studio file system Web site Regards. Husain Jagmag Hello Husain, I Think that you have to use IIS web site and not a file system site VS2005. First because every time you access to a file system site, you access it through a randomized port number, and Commerce Server needs a fixed port number. Second because the Commerce Server packager (Program that generat ...Show All
