I have a piece of code that takes two strings, puts them together, then attempts to save that result into a table in a database. For some reason, the database is only showing the second half of the string ( Me.txtRev.text in this case). When in debug, I can see that newRev is actually correct, with the hyphenated string.
Dim newRev As String = Me.revs(0) & "-" & Me.txtRev.Text

My Find/Replace Edit Menu command inside VB 2005 is not working anymore, and SQL Server 2005 as well. When I tried to check this feature in Microsoft Office applications, there is no problem at all. It's mysterious, I don't know what happen. I also tried to re-install VB and SQL, but still it didn't work.I know it is a petty problem, but it plays an important role when editing your codes.

I currently have 2 forms, one with a listview and the other with a button coded to add an item to the listview. I've just discovered though that any command, no matter how right the syntax, to a form from a different form doesn't work. The only command that does work is Form2.Show. Otherwise nothing happens. There are no errors whatsoever. All the items in each form are all set to public.

The instructions are as follows:
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.
In a tic tac toe game I am making there are two blocks of code that are identical except that they access different arrays:[code]Arrays plyrTaken and plyrPairs are used in the first block and cmptrTaken and cmptrPairs are used in the second. Is it possible to wrap these blocks into one Sub Procedure passing the different arrays when the procedure is called?
