change this:

WHERE ProductNames = LIKE'*" + txtProductSearch.Text + "*'";

to:

WHERE ProductNames = LIKE '*" + txtProductSearch.Text + "*'";

the single space between LIKE and '* is CRITICAL.

I added the space but that did not help unfortunately it returns the same error...

You can't use "= LIKE". This should work:

"SELECT * FROM ProductDescription WHERE ProductNames LIKE '*" & txtProductSearch.Text & "*'"

That right you can not use "=" with "LIKE". Also,you can try following method:
case "Product Name":
this.oleDbSelectCommand1.CommandText =      
         "SELECT * FROM ProductDescription " +
         "WHERE instr(1,ProductNames ,'"& txtProductSearch.Text &"',1)>0 ; "

I took out the = sign and that stopped the error but it would not return any thing then even if I typed it in exactly...
I even put in a little test to see what was happening by changing the button and I was getting the correct input but it still didnt work....

case "Product Name":
      this.oleDbSelectCommand1.CommandText =       
           "SELECT * FROM ProductDescription " +
           "WHERE ProductNames LIKE '*" + txtProductSearch.Text + "*'";

      btnSearch.Text = txtProductSearch.Text;
break;

all though it took a few minor changes since im using C#(+ instead of & ) the in string command was exactly what i needed  THANK YOU SO MUCH

case "Product Name":
this.oleDbSelectCommand1.CommandText =      
         "SELECT * FROM ProductDescription " +
         "WHERE instr(1,ProductNames ,'" + txtProductSearch.Text + "',1)>0 ; "
