View 2 RepliesI am looking for a bit of inspiration here, a client has requested me to build a simple remote process monitoring application with capability for smtp notification, when monitored processes go down or come back on-line. Can anyone point me in the direction of some sample code to get me started. I have briefly looked at .net remoting as a potential development path, from my understanding of how this works, the remoting architecture would require both a client and remote server component, (though I am not a 100% sure on this one), however if this is the case, then it will not fit the bill, as one of the fundamental requirements is that no additional software can be deployed on the servers which are to be monitored

The sample program for the Chart Control is written in C#. It provides VB snippets but there appears to be a key piece of information missing or at least hidden. Can anyone explain to me what is needed to get the Chart Control working in VB.NET VS2008 Pro?Using the Chart Controls sample, I tried to create a RangeBar. The only thing showing is a big red X across the chart. Here's the code almost exactly as taken from the VB sample:

View 1 RepliesI downloaded some VB 2008 sample project from the net.Initially they seemed to run fine. But then they stopped running. They fall over when an attempt is made to connect to the northwind database. The error messge says something like "the sql or sql express and the northwind database has to be installed ". Which of course they are .
One possible reason that the code stopped working is that I tried to move the SQL on my Pc from one drive to another ( I moved it to another hard drive using cut and paste ). When I realise the Vb code had stopped working I simply reversed the above procedure, i.e cut and pasted back to the original drive.I think I should also add that there any different versions of sql on my PC, and I think the one that I cut and pasted is not the one used by the sample project.
We are moving from VSS to TFS2010 and I need to convert a program that does the checkout and update of items. Does anyone know of a good example of how to use the TFS2010 API to find and item and check it out and then check in the new version?
