Save in database didn't work ?! (VB.NET | OLE) -

-

I use the following code to edit the user, the code does not give me an error code, but at the same time It does not work anymore, the data are still without any new changes: 

  dim an a string A = combo 3 Text & amp; "/" & Amp; Comb2.Text & amp; "/" & Amp; Comb1.Text Dim SavInto New OleDb.OleDbCommand Dim ConStr as string = _ "Provider = Microsoft.Jet.OLEDB.4.0; Data Source =" & amp; _Application Startup path & amp; "\ Base.mdb" New OleadBConnect (Concert) Conn. Open () Sevinato.connection = ConSavinO Type Commands = CommandType Text Softino Common Text = "Update TB Sts Tasalsol = '" & amp; _ Trim (frm.tx1.Text) & amp; _ "', Enamor ='" & amp; Trim (frm.TextBox2.Text) & amp; _ "', Name =' '& amp; trim (frm.tx3.Text) & amp; _"', rotba = '& amp; Trim (frm.tx4.Text) & amp; _ "', Space ='" & amp; Trim (frm.tx5.Text) & amp; _ "', End-current ='" & amp; A & amp; _ "'WHERE notes ='" & amp; Trim (frm.tx8.Text) & amp; "'" SavInto.ExecuteNonQuery () Conn.Close () frm .tx1.Text = Me.tx1.Text with TextBox2.Text = Me.tx2.Text .tx3.Text = Me.tx3.Text .tx4.Text = Me.tx4.Text .tx5.Text = Me.tx5.Text. Tx6.Text = One. Tx8.Text = Me.tx8.Text end frm.Show () with Me.Close ()

I wrote the whole code, what is wrong with ?! And thanks

Note : There are some columns that can have a lot of data in its cells

Intelligent advice about using a parameterized query instead of lot where the section looks very strange, you really want to make sure Want to use the "Notes" field to update a row? And tx8 is an editable field? Why are you triming it? It seems that the best way to find the line to update is through a field called "Notes", which appears plain text that requires trim.

It is better to use the ID of the question (or rows) to update this lot .

Note that you are not seeing the return value of ExecuteNonQuery - I suspect that it will return 0 to indicate that it does not update any rows. He should check that.

In addition, you should use the use statement for both connections and commands, so that they can be dealt with properly and the exception is also thrown.

Just to repeat: Please, please use parameteric queries instead of embedding values ​​in SQL such questions like DBA cry.

-
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.
