• Visual Studio 2008 (Pre-release) Close the Window in UserControl

  I put a usercontrol in a window. when I click a button in the usercontrol, I want to close the window and show another window. can this be implemented Thanks Do your design constraints prohibit the UserControl from having a reference to the containing Window or the Window knowing about the UserControl If the user control can know about the Window, then just expose a property on the control which the Window sets to itself (i.e. the Window gives the control a refernce to itself). Then the control can just call Close on the Window reference. Otherwise, perhaps you might expose an event on the user control called CloseWindowRequested. The Window would hook that event and close itself when the event fires. If neither of tho ...Show All

• SQL Server Number of Queues Best Practice ?

  Hi There In terms of scaling out Service Broker to hundreds of instances, would it be better from a performance perspective so have one queue with all the messages coming in(obviously with a high number for max_queue readers), or create a number of queues and spread the messages across them Or is there no significant difference. The one reason i am leaning towords multiple queues is so that is poison messages are found or a something lese goes wrong with a queue not all messages are affected, however creating multipple queues makes it more complex and required more administration Any general best practice when it comes to this Thank You W/o knowing all details about the app, I'd probably ...Show All

• Software Development for Windows Vista IE 7 crashes

  Hey when using Vista I have discovered that every single time I open IE 7 it crashes. The toolbars don't load it's just a white box with a title bar nothing else. My computer locks up and then everything goes at a snails pace. Once I eventually get the task manager open, I try and end the task. It gives me the option of restarting the task, or leaving it be. I tried both but the same thing happened again. They only way to fix it is to restart. I'm geussing this is a Vista issue because under XP it seems to work fine. (Edit) - Now when IE opened because I clicked a link in Messenger it opens with toolbars, dosen't copy the URL over and when I type a URL in it just goes and crashes. My whole laptop crashed ...Show All

• Visual Studio Express Editions clicking a picturebox

  I have about 200 little pictureboxes that start simply white. When they are clicked they turn black. I'm using picture boxes because they are the only thing that can get as small as I need them. I'm hoping for a way that I don't need to re-write the code that many times. I've tried using Private Sub PictureBox1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click Me .BackColor = Color.Black End Sub But that changes all the picture boxes and textboxes and forms backcolor to black. I'm hoping there is some simple solution that I'm missing. Thanks for any insight. your code snippet is showing that you are setting the back color of the FO ...Show All

• SQL Server Does SQL Server 2005 Express has the method that delete automatically rows ordered by time column.

  Hi, I made table that stores monitoring data every 1 minute. It should have only 60 minutes-data from current time. I delete data which stored 60 minutes ago before insert. I'll be happy to find that the database engine does automatically above procedure. You could use an insert trigger which fires when new data is inserted. Place your delete statement here to delete old records. -- SvenC ...Show All

• SQL Server Foreign Key Constraints execution order?

  How can I get and or set the order in which the cascading deletes of a table are executed I have table A with cascading deletes to Table B and Table C. Records in table B can not be deleted if they are referenced from table C. So if I delete C, then B and then A; that would work. But B then C and then A might be prohibited due to the constraint between B and C. Therefor the order of execution of the cascading delete is important. hi, it will cascade as long as you dont have something which would result into to a circular reference like C has a fk on A regards, joey ...Show All

• Software Development for Windows Vista Oracle Client software in Windows Vista

  Hi, I was wondering if anyone knows how to get the Oracle client software to work correctly under Windows Vista. I have tried reinstall it and I still get the problem. Every time I try to do something that obviously relies on it (like even viewing a database in the server explorer in VS2005) I get the message: "System.Data.OracleClient requires oracle client software version 8.1.7 or greater." How to I fix this Thanks for any help, Richard Hi Richard The Oracle database client needs to be installed using administrative privileges. If you use UAC , this will interfere in setting up the oracle client correctly. Besides this you must run Visual Studio as administrator and your program that ...Show All

  We just installed Team Foundation Server Suite. I can access it from the same machine but when I try from other machines, I get a failure notice, TF31002: Unable to connect to this Team Foundation Server.

• Visual Basic Simple security validation

  I am curious if there is a simple way to identify a system that a VS2005 VB application is connecting to. Using "windows login validation" types of things is not an option. I notice there is a registry key in the local machine, software, microsoft, mslicensing called "HardwareID". Would there be any security concerns accessing this value from within a program and would it be unique to a machine Does it change If thats not the right place to be doing this (and I am trying to avoid making a new entry someplace if possible) then is there an alternate or better approach Thanks in advance! :) thats pretty much how you would call it.
