Answer 1

Given:

Dim strOrig = "010451-09F2" 

You can do any of the following:

Dim leftString = strOrig.Substring(0, strOrig.IndexOf("-")) 

Or:

Dim leftString = strOrig.Split("-"c)(0) ' Take the first index in the array 

Or:

Dim leftString = Left(strOrig, InStr(strOrig, "-")) ' Could also be: Mid(strOrig, 0, InStr(strOrig, "-")) 

Answer 2

Dim str As String = "010451-09F2" Dim leftPart As String = str.Split("-")(0) 

Split gives you the left and right parts in a string array. Accessing the first element (index 0) gives you the left part.
