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:

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
