"Cannot Find Table *number*"?
Feb 23, 2010
I'm new to SQL database work but I'm sure the problem lies with this line:
dr = ds.Tables(0).NewRow()
I'm not sure what the (0) represents, I just followed a tutorial somewhere and it worked fine for that.

An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))

I have a Credit Card Number in an XML Message and I want to use a regex to find the Credit Card Number and encrypt it. All numbers are 16 characters long and they are not always in the same place in the xml, so basically I think I just need to find a string that is 16 characters and decrypt it, but I am not sure how.

I am creating an application and I have the numbers 1 - 20. Each number represents a location. They are continuous. I need a way to find the closest number to a given location. For example if the event is in location 8 and there are 2 people who can attend who are in locations 6 and 10. Then zone 6 would be chosen as its closest and also the lowest. If I needed the next highest closest number then I could pull all of the numbers into an array and sort them and then pull out the one which is the next highest zone. However as I need to find the closest number which could be lower, im not sure how to achieve this.

How do I find the number of USB ports available, and what their references are. Example there are 6 USB ports on my motherboard what code would I use to find their reference like, port 1 is called 0 and port 2 is called 1. I want a user to select a designated port and save the selection to a config file so that whenever the user plugs in a removable diskdrive into that specific port a dialogue box will popup asking the user if they want to backup their designated folder (path will also be saved in config file) to that removable diskdrive. I know how to do everything like copying the folder to the diskdrive and all that I just need a code snippet to find the system reference to the USB ports.
