ms access - Error in getting Dates in database (BETWEEN Clause| VB.NET|OLE) -

-

Shortly before, I used a code to get between 2 dates from the database (date With column dd / mm / yy), I think it works best for the first time, the code is:

New date in the form of a slow B as a whole (a value) Tx2.Text) b = System.DateTime.Today B = B. Ed. (-a) MSBBC (B) Con. Open () SQLRR = "Choose from TB * where between the last circuit # 01/01/1800 # and #" & amp; B & amp; "#" Dim DataAdapter1 New OleDbDataAdapter (SQLstr, Connecticut) DataSet1.Clear () DataAdapter1.Fill (DataSet1, "Tb") Conn.Close (as in)

As you see , Enter a number to the code user and make it today by making zero, then calculate the date I want, after that I use the pen to get all the dates between them

< P> But now, this code gets some data and overrides others, I mean Some dates are between TWOs, but the code never gets, why does this happen?

If you look at the generated SQL string, then what is your hope on that date? is? I think it would be a database that it is necessary to follow a specific format (either dd / mm / yyyy or mm / dd / yyyy Coded date is given). Could it be that your day and month switch changes when a string version of the date is created and put in your SQL query?

As a side note, if possible, use parameterized queries instead. It may also remove some types of conversion problems.

Update
Here is an example of using a parameterized query on OLE DB for a database:

Just want to know how I will create UIPickerView in a UIActionSheet with a simple array. Well, I really know how to put it in an action sheet but I like my way because it is more for my app, thanks, but I I also want to know how to put options in UIPKviewView, I just have an array with colors already on top of that part: red, green, blue, yellow, black, etc. in this, but I want to know how it In the preview d L'be if I am using the already Instifrem:? Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
