• Hanspeter FileSystemWatcher in arraylist

  Hi all, I'm trying to monitor changes in a number of folders using FileSystemWatcher. I have a procedure that accepts the path to monitor. A new FileSystemWatcher is created for that path, together with its event handlers, and added to an arraylist (watchList). This seems to work fine, however I would like to be able to modify the attributes of specific watchers at run-time. I'm doing something like this to stop the first watcher in the arraylist: Dim w As FileSystemWatcher w = watchList.Item(0) w.EnableRaisingEvents = False This causes a NullReferenceException at the last line. In break mode I see the arraylist has 3 elements of type Object, but adding a watch for watchList.Item(0).path (or any other watcher pro ...Show All

• 87jerome Inserting a record into a Gridview

  I am using Visual Web Developer 2005 Express Edition, with VB and SQL Server 2005 (express). I want to have a gridview that will edit/update, delete, and insert records. It should be easy - editing and deleting are simply a matter of checking a box on the smart tag. But how do I insert a record I was expecting another check box option that would handle it all (perhaps with an empty row at the bottom, in the manner of Access and SQL), but I've not been able to find such an option. Do I have to create an event handler - if yes, what event, what do I write I haven't been able to find anything in the help, or in the forum. This is such a basic question - have I missed something obvious Regards, Robert ...Show All

• Joe Kehnast I'm making a conversion program.

  For those of you who know me, I've finally settled on an idea for a program. It converts (for starters) from anything that ends with meters (you know, centimeter, millimeter, kilometer) into anything else that ends with the word meters. You get the idea. I'm useing combo boxes, and I need to assign values to the names in the box, so they can be multiplied. Like, the selection (this is exactly what it looks like) "centimeter(cm)" needs to be assigned the value 0.01. How do I do that, and make it so that when one thing from one box is selected, and one thing from another box is selected, and a button is clicked, they get multiplied together Thanks. The above code i have posted does the matter: ...Show All
