Oledb - SELECT Through Oledbcommand In .net Not Picking Up Recent Changes?

Sep 28, 2009

I'm using the following code to work out the next unique Order Number in an access database. ServerDB is a "System.Data.OleDb.OleDbConnection"

Dim command As New OleDb.OleDbCommand("", serverDB)
command.CommandText = "SELECT max (ORDERNO) FROM WORKORDR"
iOrder = command.ExecuteScalar()
NewOrderNo = (iOrder + 1)

If I subsequently create a WORKORDR (using a different DB connection), the code will not pick up the new "next order number."e.g.

iFoo = NewOrderNo
CreateNewWorkOrderWithNumber(iFoo)
iFoo2 = NewOrderNo

will return the same value to both iFoo and iFoo2. If I Close and then reopen serverDB, as part of the "NewOrderNo" function, then it works. iFoo and iFoo2 will be correct. Is there any way to force a "System.Data.OleDb.OleDbConnection" to refresh the database in this situation without closing and reopening the connection. e.g. Is there anything equivalent to serverdb.refresh or serverdb.FlushCache

How I create the order.I wondered if this could be caused by not updating my transactions after creating the order. I'm using an XSD for the order creation, and the code I use to create the record is ...

Sub CreateNewWorkOrderWithNumber(ByVal iNewOrder As Integer)
Dim OrderDS As New CNC
Dim OrderAdapter As New CNCTableAdapters.WORKORDRTableAdapter

[code]....

OleDbCommand Select Returning Null

Feb 16, 2011

Having trouble importing a value from a .csv file to a .csv file. This this done because data needs to be massaged and the data file renamed. This is a user interface. Do not want to have the user touch the .csv in any way except upload to the application so the applicaiton can do manipulation. Either way here is the issue.

There is a column in the original .csv file that contains a zip code. The first row of the .csv has a value of 17003 in the zip code column. In the second row of the .csv the zip code column has a value of 11746-9984. The value in the zip code column from the second row always comes back as a Null value. My guess is that the OleDbDataAdapter is defining some kind of Schema. Again, the first row containing the zip code column probably insists the value must be numeric. When the data table field is established it probably gets defined as numeric. If that is true and the second row of the .csv zip code column is not numeric that must cause the zip code value to be Null.[code]...

Efficiency Of Oledb - Got 10+ Users Using Files, Via A Oledb To Put Info Into An Excel Spreadsheet

Oct 18, 2010

Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

OleDbCommand Named Parameters And Order Of Addition?

Apr 8, 2012

I have an ACE OleDb connection to an accdb file that�s working well but I�m mystified by something I recently discovered when using named parameters. Order of adding of parameters overrides the parameter names. I see in the MSDN that is states when in "Text" mode named parameters is not supported. My testing has proven this to be the case. The example below puts "Value 2 in Field1 and "Value 1" in Field2. In fact I could change @value2 to @blahblah and it works.

Dim command As New OleDb.OleDbCommand("INSERT INTO Results(Field1,Field2) Values(@value1,@value2)", con)
command.Parameters.AddWithValue("@value2, "Value 2")
command.Parameters.AddWithValue("@value1", "Value 1")

what is text mode and how do I change it and what other types are there? According to John McIlhinney�s earlier explanation things like date variables are added in a binary fashion including support for DBNull. So this is not "Text" so how am I sending binary data to a Db in Text mode? I�m just not getting why it supports names when it ignores them. Is it simply the case that there is no way to add parameters out of order in my case?If adding out of order is impossible should my command use some other syntax? I see other syntax that just uses question marks in the command dim for the Values section. EG "Values(?,?)".

Is there a way of adding parameters without names?In general I�d love to hear someone to explain this so I can understand the inner workings here a little better and have a little more confidence in what I�m doing here. I can fix my code to work but I feel like an idiot using parameter names that are ignored. I just know I�m doing something wrong even if it works.

Picking Up Individual Keys?

Feb 10, 2009

I am making a HTML editor and thats the easy par ie saving as .html etc, but i want to also add in the thing thats in VB wherein it picks up the word your typing and make suggestions, i have made it so it can have a data base of a thousand words (1000) and you can add and it loads all fine. Now i need to add in the functionallity to read every Key, i tryed

Code:
If e.KeyCode = Keys.Space Then Scan = ""

But none of this works, is there a better way of getting the the key press and adding it to a string untill space is pressed in which the array is cleared.

Code:
Imports System.IO
Public Class Form1

[code]....

So say i had a Tag stored that was "HTML" then as soon as i pressed the < key it would start checking my keys then if i pressed H it would display all word is the drop down box with H at the start then if i followed it with T then M it would show HTML in the box and maby a couple of others that began with HTM, if i then hit enter it would add in the L> thus compleating it and printing "<HTML>"

Picking Up Strings From CMD Command?

Jan 29, 2010

So I've tried Process and starting a cmd.exe and send commands directly to that window. And then picking up the values written to the cmd.exe window.

Dim arrServers As ArrayList
Dim s(ListBoxServers.Items.Count) As String
ListBoxServers.Items.CopyTo(s, 0)
arrServers = New ArrayList(s)
Using P As New Process
[Code] .....
But is looks like it doesn't "press enter" or something. Meaning, I don't get any results from the command. I don't even get a "'command' is not recognized as an internal or external command, operable program or batch file." like you normally get if it doesn't understand the syntax.

Script To Say .jpg OR .bmp - Picking Whichever It Is?

May 15, 2012

We use some software at work called nicelabel, which prints out box end labels by dragging data from a database. We currently have two templates that we use, one for jpgs and one for bmps. For example this is the code that is ran on the picture on our box end label -

[Code]....

Now, if the relevant image in the folder is a .bmp, the process will fail and no image will be assigned to the box end label. Vice versa with if we run the .bmp version of that code and it's a .jpg. Is there any way we can modify that script to say .jpg OR .bmp, picking whichever it is? For example, look for this file with a .jpg at the end, if you cant find it look for this file with a .bmp instead?
