View 2 RepliesI am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.

i am new to working with databases, I have done some of my own research and have been adding and regtrieving records without trouble. Now I need to retrieve a specific record based on a selection made by the user. I found that the way to do it is with the WHERE statement and from examples i have seen the code below should be how it is done:[code]The problem I am having is that when i try to run the sub i get the error:Syntax error (missing operator) in query expression 'Show Name = Strictly Hip Hop'.The show name is in the database because that is where the data is retrieved from. All I am trying to do is populate a text box with information from the Host column when the Show Name column is the same as the selected item in the combo box.
