• Visual Basic How can I search a database on multiple criteria selected from listboxes?

  I am new to VB and I am finding it difficult to understand. I am using Visual Studio 2005. I want to search a database for several items, I am using the My Movie Collection template to practice with and I want to be able to search for actors, directors and release dates and see the movies that match. I want to use listboxes for the items to search on and populate them with the possible options from the database. Ideally I would like the results to be updated as I click on the options in the listboxes (no 'search' button). I want to be able to click on more than one item in a listbox (e.g. several dates) and I want to be able to deselect items that I previously clicked on. I have found examples of searching for one thing in a datab ...Show All

• Visual Studio Team System TF30063: You are not authorized to access <servername>

  Every few days one of our team members receives this error when attempting to check files out of version control. I have seen other postings related to this error, but it seems that it occurs when using proxies or other configurations. These solutions do not apply to use because we are using the single deployment model for TFS.  At present time our workaround is to have the developer reboot their workstation. Is anyone aware of the root cause of this problem and how to solve it Thanks Mario. I have been unable to reproduce this to help identify the problem, but I will be sure to post again if it happens. ...Show All

• Community Chat network security

  Hello, Can anybody tell me of a good website that provides information about network security Someone recommended www.infolocktech.com . Any recommendations on this werstyle teen Windows XP already comes or has available network security. What with windows live update, defender,firewall, and security center everything is covered. I was told that security center has virus protection, so I removed my copy of McAfee. Security Center then said I had no virus protection. It offered a link to fix this, but it was so busy, I couldn't get through the site. I wound up downloading and purchasing a security center from download.com. I know that security center has virus control because it automatically downloaded a virus update from microsof ...Show All

  As the title states, what software will be good to have. I am going to download Visual C# Studio Express, but what else is good for stuff like graphics or sound.

• SharePoint Products and Technologies Create Task Activity has correlation token conflict when in While Loop

  Hi everyone, First time posting here. I'm having a problem with developing a MOSS Workflow. The scenario is this: Within my workflow, I have a while loop construct. Within this while loop, there is a series of CreateTask->Wait for Task to be Changed -> CloseTask. It works fine until it loops back around to try to create another task with the same correlation token. In fact, that's the error I get. How do I get around this issue by disassociating the token or something like that. Thanks in advance for any help. rnellis2002 What you can do is use a replicator that contains a sequence activity, within that sequence you can then use CreateTask, onTaskChanged, and CompleteTask.
