• Software Development for Windows Vista Wait until time/Persistence & Tracking

  Hello, I have to questions based on waiting/persistence/tracking scenarios: 1. Suposse that I want to wait until a specific day. If I use a delay or something like that I understand that at this point the wf becomes idle and the persistence service writes it down. What happens later if I turn off the runtime engine and I want to start it later. How do I continue with the saved instance without explicit set this Is there any standard solution to this 2. Suppose that I want to track the wf states and I implement a tracking service that also persist data. How do I solve the scenario where the wf has changed but the tracking updates are interrupted Does anyone know a solution or better approach to them Regards, M ...Show All

• SQL Server Distributed processing "farm" using Broker for middleware.

  In our current project, we are attempting to use Broker for the middleware for a "queuing" solution that helps in throttling & load-balancing incoming messages. These messages could potentially be either long-running jobs or simply an incoming flood of messages received from our integration web services that are called upon via BizTalk. For the posting of messages onto the "to do" queue, we are implementing the "fire & forget" pattern that has been discussed here previously and on Remus' blog. This aspect of the design seems to work fine for us. Currently we have this setup where activation is occuring on the target queue, but we don't want to hold open a thread there on the server while waiting for ...Show All

• Software Development for Windows Vista Questions on managing a large number of users

  I have a question on whether CardSpace can be used in the following scenario. Just wondering if anyone can point me in the right direction. I have a system that will employ approx 250 laptops and approx 2500 users. I want to use CardSpace to store information about each user and provide the authentication for the users. For the most part, each user will only be using 3 different laptops, and each laptop will have a total of 100 users. I would like to be able to store all the cards on a main server, and have the server download the cards to the laptop as needed. I also have several fields on the card that are expiration dates, making the card invalid. Can something like this be done in CardSpace Thanks for the help, Joe ...Show All

• SharePoint Products and Technologies Install WSS 3.0 with Search but without SQL Server

  I'd like to make a full WSS installation with the exception of SQL Server Express. If I choose "Basic" or "Advanced -> Full" intallation scenarios it installs SQL Server and I cannot uninstall it separately. If I select "Web Front-End", it then lacks search service (as per imbedded help). Is there any workaround well, as often, the way around the settings pre-defined for wizard is command prompt. So these two commands brought me a fully functional database connection and working Central Administration site.

• Windows Forms Windows 98/.Net Framework Problem

  Hi, I have a ClickOnce, VB Express application that is working fine on many clients, except for a client who is stuck in the world of Windows 98. I have uninstalled, rebooted and re-installed .Net Framework 2 several times. The reboots seem clean, but when I attempt to Run the application, the file is downloaded and then Windows asks if I want to Run or Save the file. In either case, Windows attempts to open the file, Prize%20Money[1], but of course there is no application associated for this file. I assume that there is a problem with either Windows 98 or .Net Framework 2, but I don't have clue where to begin. Although, I'd like to tell the client to upgrade his old iron and get Windows XP this is not an option. Thanks for your sugg ...Show All

• Windows Forms DataGridView - How is mouseDown implemented?

  Hi I've made a class that inherits from DataGridView. I have overridden the mouseDown like: protected override void OnMouseDown(MouseEventArgs e) { DataGridView.HitTestInfo hti = this.HitTest(e.X, e.Y); if(e.Button == System.Windows.Forms.MouseButtons.Left) { if(hti.Type == DataGridViewHitTestType.Cell) { if(this.RowChanged != null) this.RowChanged(this, new MyProject.DataGridViewRowSelectionEventArgs(this.CurrentRow, this.Rows[hti.RowIndex])); } } As you see, I do not select the row pressed, because I want to have this done outside the control. (Because sometimes I ask the user if she wants to select/unselect that row). Then to select/unselect a row I have a method: public void SelectRow(int index, bool selected) { this.Cu ...Show All
