Well, I got some code below, but apparentally setting the Timer's to an interval of even 1000 (1 second) lags pretty bad,especially when both are checked, is there some kind of way to hook onto the memory so I know when the value is changed?What I think I have to do is likely hook onto all the characters that were there originally, +1 after in case the string changes only to get longer, and doesn't change the originally found characters.Then when a change is detected, then it will read again.I am simply trying to make the code run without lagging.

Really weird issue, perhaps someone can shed some light. I have a windows form with a combobox. When you make a selection it's supposed to update another control, so I have
Private Sub LoadAssociatedLocations() Handles combobox_categories.SelectionChangeCommitted
Dim test As String = combobox_categories.Text I've done this in other winforms projects without issue, though for some reason in this case, when the combobox is changed, combobox.Text has the value of the previous selection. The SelectedIndex value is the connect index, but Tex is always the text of the previously selected index. I can just use selected index of course, but I'd like to know what's causing this strange behavior.
I have things set up so that the program is ready to start logging ,only when Recieving=true.This is controlled with Button1. So I click button1,Serial port is open and waiting for some signals from the Dyno.When 1 signal come it put a "1" in TextBox1 ,and for the second a "2" and so on. Thing is sometimes it starts right away, like I want it to,and sometimes it lags a fraction of a second, even though the Port is open.When it lags there are already 5 to 10 signals gone by before it starts logging 1,2,3,...and so on. Sometimes it don't start at all.Then I have to close and re-open the form and it works,but with lagging on the first "set"
"Textbox1 > 0 then" triggers a timer (not seen in this code)that samples Textbox1 once pre interval and writes the value to a listbox. On the upside as soon as a "1" is displayed in textbox1 the timer starts like it's supposed to.I noticed this behaviour before I added the timer and besides the timer has nothing to do with the signals coming from the SerialPort. I have my form setup so I can run "sets".Run one "set"...save...reset...run another "set" ...and compare.It's always the first "set" thats off.If I run multiple "sets" the first one is completely "whacked", and the rest are consistent.
Think this could be the SerialPort lagging,or code problems?

I am trying to rewrite some code and I am trying to determine if I am writing it correctly. My goal is to make sure that the old code and my new code produce the same results(i.e. are logically equivalent). Are the 2 code blocks below equivalent?

I am using VB.Net 2003 with an Access 2000 database. The program contains three options for the content of a DataGrid, each from a different table. I have finished programming the DataGrid which loads as the default when the program starts.When I run the program the DataDrid appears, but it is empty, except for a small box with a "+" in it. I click the + and the table name appears, I click the table name and the DataGrid is populated exactly as I wanted it.

How would I change this code to make the factory dynamic. I believe I was close with remoting. I don't want any hardcoding of the factory, nor do I want to have to recompile. The database drives it.
