• .NET Development AccessViolationException with C# Ping class

  I have a "watchdog" program, c# console application, coded with VS 2005. Program runs every 3 minutes. And one part of program checks pings to ~20 ip's. I'll give that function code: static private bool ping ( ref String ip) { bool success = false ; Ping pingSender = new Ping (); if (pingSender.Send(ip).Status.Equals( IPStatus .Success)) { success = true ; } else { success = false ; } return success; } Usually this works.. but sometimes (once a day on the average) it throws an exception and program crashes: Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I checke ...Show All

• Windows Live Developer Forums PushPin Pop-up with small map zoomed...

  Hello all, Just got into VE, it's a lot more fun to figure this one out than the others. I hope the community continues to grow. I have been cracking the surface of using VE in the past week and have been trying to get a small map to show up in the pushpin roll-over div. I am not sure how to approach this, so what I started to do is create a fuction that creates another instance of the MAP, but with the current lon/lat and a closer zoom to see the pushpins exact location much closer. I can't figure out how to get this into the DIV popup... it's driving me nuts. Is this possible in VE I am sure it its, but not sure what all is offered in the current version of the VEPushPin constructor.. Any help would be cool. Thanks! Yeah, I see ...Show All

• Visual Studio Express Editions Automatically Fill in Array

  hi im trying to automatically fill in an array with incriments between the numbers 0 - 5 but i want to be able to automatically change the incriments eg. incriment of 1 puts the numbers 0, 1, 2..5 into the array while an incriment of 0.5 puts 0, 0.5, 1.......5 in the array etc. the reason im doing this is because the user will be able to adjust the accuracy of some calculations by changing the incriment. and i want the array, which will be used for the calculations, to automatically adjust. this is what ive got so far Public Class Form1 Private Sub cmdGo_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGo.Click Dim array() As Double For t As Double = 0 To 5 St ...Show All

• SharePoint Products and Technologies Setting the ContentType for a new SPListItem in a SPList?

  How do you set the ContentType property when adding/creating a new SPListItem in an SPList An SPListItem has a ContentType property but it is read-only in the WSS 3.0 object model. We prefer to do it directly through the object model (vs. CAML or a web service). Here's an example: http://www.sharepointblogs.com/tonstegeman/archive/2006/08/06/9763.aspx It will be interesting to see where this is documented in the WSS 3.0 SDK. ...Show All

• SQL Server Access to TaskHost from derived Task class.

  Hi, for some reasons, I have to get access to the TaskHost during validation and execution. For example, I wanna know, if my task is within a container or not (parent is Sequence).

• SQL Server Should I use indexes?

  I have a very large table (about 200,000 records), but there are only 2 fields in the table only one populated with data. I need to update the 2nd field with the first field's data. UPDATE Table1 SET field2 = field1 This is taking a really long time to run about 3.5 minutes. Is this normal Can I create an index What can I do to shorten the run time Thanks, Ninel I'd assume that the update would be faster if the index had a low fillfactor... but so as not to merely speculate, I tested on my end...  Turns out, with a clustered index in place, the update is quite a bit faster.  Lower fillfactors are indeed slightly faster, but not much.  ...Show All

• Visual Studio 2008 (Pre-release) Where are the Windows Forms controls equivalents?

  Hi, I was wondering if we are going to see equivalents of the Windows Forms Controls and Windows Forms capabilities in WPF. Although WPF seems impressive, it lags the Windows Forms power and its also counteractive. My point beeing in addition to training we will need to focus on developing a UI framework ontop. Thats going to waste time. Why cant we have the existing windows forms controls in WPF as they are right now in .net 2.0 ...Show All
