  • What does `const` do when combined with `readonly`?

    - by Byron Sommardahl
    The difference between const and readonly is well covered. A const can't be changed and a read only can only be changed in a constructor. But, what happens when you combine the two: public readonly const string how_does_this_behave = "I don't know"; The compiler allows it. But I'm not sure how it behaves from this point on. Thoughts?

  • Help finding a USB Joystick mouse?

    - by shane87
    I am currently developing a final year project which involves using a joystick instead of the mouse for those who are physically impaired. Does anyone know where I can find a USB Joystick mouse? All I can find on e-bay and amazon is very sophisticated flight joysticks with loads of buttons and controls etc. I am looking for a plain and simple joystick? If anyone could point me in the right direction I would be very grateful.

  • Why am I losing sessions when running in StateServer mode?

    - by Nick Allen - Tungle139
    I have checked the servers (Win Server 2003) application event logs for the following problem http://support.microsoft.com/kb/308097 which doesn't show up. It just appears that sessions drop randomly for random users It's a single server setup, no web farms and no load balancing Even though the issue I point to above doesn't occur in the logs, is it worth increasing the stateNetworkTimeout attribute anyway? The configuration at the moment is simply <sessionState mode="StateServer" cookieless="false" stateConnectionString="tcpip=localhost:42424" timeout="60"/>

  • File Folder copy

    - by Dario Dias
    Below is the VBScript code. If the file/s or folder exist I get scripting error, "File already exists". How to fix that? How to create folder only if it does not exist and copy files only that are new or do not exist in source path? How to insert the username (Point 1) after "Welcome" and at (Poin 3) instead of user cancelled? Can the buttons be changed to Copy,Update,Cancel instead of Yes,No,Cancel? (Point 2) The code: Set objFSO = CreateObject("Scripting.FileSystemObject") Set wshShell = WScript.CreateObject( "WScript.Shell" ) strUserName = wshShell.ExpandEnvironmentStrings( "%USERNAME%" ) Message = " Welcome to the AVG Update Module" & vbCR '1* Message = Message & " *****************************" & vbCR & vbCR Message = Message & " Click Yes to Copy Definition Files" & vbCR & vbCR Message = Message & " OR " & vbCR & vbCR Message = Message & " Click No to Update Definition Files." & vbCR & vbCR Message = Message & " Click Cancel (ESC) to Exit." & vbCR & vbCR X = MsgBox(Message, vbYesNoCancel, "AVG Update Module") '2* 'Yes Selected Script If X = 6 then objFSO.FolderExists("E:\Updates") if TRUE then objFSO.CreateFolder ("E:\Updates") objFSO.CopyFile "c:\Docume~1\alluse~1\applic~1\avg8\update\download\*.*", "E:\Updates\" , OverwriteFiles MsgBox "Files Copied Succesfully.", vbInformation, "Copy Success" End If 'No Selected Script If X = 7 then objFSO.FolderExists("Updates") if TRUE then objFSO.CreateFolder("Updates") objFSO.CopyFile "E:\Updates\*.*", "Updates", OverwriteFiles Message = "Files Updated Successfully." & vbCR & vbCR Message = Message & "Click OK to Launch AVG GUI." & vbCR & vbCR Message = Message & "Click Cancel (ESC) to Exit." & vbCR & vbCR Y = MsgBox(Message, vbOKCancel, "Update Success") If Y = 1 then Set WshShell = CreateObject("WScript.Shell") WshShell.Run chr(34) & "C:\Progra~1\avg\avg8\avgui.exe" & Chr(34), 0 Set WshShell = Nothing End if If Y = 3 then WScript.Quit End IF 'Cancel Selection Script If X = 2 then MsgBox "No Files have been Copied/Updated.", vbExclamation, "User Cancelled" '3* End if

I have thought about creating an prereq command line app to detect the old version and uninstall, but would like to avoid having to write an something like that where it only get's run once.

  • Best way to learn SQL Server

    - by Jason Baker
    So I'm getting a new job working with databases (Microsoft SQL Server to be precise). I know nothing about SQL much less SQL Server. They said they'd train me, but I want to take some initiative to learn about it on my own to be ahead. Where's the best place to start (tutorials, books, etc)? I want to learn more about the SQL language moreso than any of the fancy point and click stuff.
