Presently have a few listboxes pulling data from sql database.
Have a button that will be used for deletion of data with pop-up verification.
Found many tutorials that cover issue of deleting from basic listbox, but not within sql database as well.

Using field name: "ClientName" for display within listbox.
So, I am guessing I would have to focus on two elements:  ClientName and Row Selected

Unclear about proper code for deleting sql data according to row selection of listbox.

What would be easiest?



Feedback always appreciated,

Have been digging around to find the answer myself. Still no luck.  Web tutorials focus on deleting from listbox contents.
As I mentioned, deleting from the listbox's contents is no problem, it's having the code also delete sql data that is the concern.

I have tried modifying sql code to include listbox selection, but still no luck.  I know I am close, I just need some guidance.

Here is what I tried using: 

myCommand.CommandText = "DELETE FROM ModuleName where ClientName = ListBox1.SelectedItem"

Using field name: "ClientName" for display within listbox.
So, I am guessing I would have to focus on two elements:  ClientName and Row Selected

Unclear about proper code for deleting sql data according to row selection of listbox.

What would be easiest?

myCommand.CommandText = "DELETE FROM ModuleName where ClientName = '" + ListBox1.SelectedItem.Text + "'"

I'd try that line.
One thing I do to test my Generated SQL is to output the SQL before I run it and then test it in a DB manager for any execution errors.

Hope that can help.

Success!
This code works correctly. I figured it was a small tweak to existing code.
Nevertheless, I appreciate such a timely response.

Have 2 other questions you might be able to answer easily. Thanks again.



Repeating a command without re-writting code under each event?
