Make An Oledb Connection To An Access Database : Invalid Authorization Specification

Sep 15, 2007

I am trying to make an oledb connection to an Access database.

1. I added a component class.It said drag from the toolbox to add components.

2. I dragged over the Oledbconnection and OledbdataAdapter

3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)

4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.

I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?

Check Internet / Network Connection ?

Nov 19, 2011

This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.

If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.

If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...

Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.

I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.

All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.

How To Detect Computer Network Connection Status

Jun 8, 2011

I have a problem when trying to detect the computers network connection status.

Here is the code I have used:
Dim IsAvalible As String = My.Computer.Network.IsAvailable
If IsAvalible = True Then Label1.Text = "Connected" Else <code>
<code>If IsAvalible = False Then</code> I <code>
Label1.Text = "Disconnected"</code></code>
End If [/ICODE] End If[/ICODE]

But for some even when the network is disconnected or the computers wifi is turned on I still get the result of "Connected". I think there something wrong with the code.

VS 2010 - What To Do When Network Connection Drops With FileSystemWatcher

Jul 15, 2011

I can't see anything in the method list that lets you know when a connection drops (and since it's constantly checking, it seems that could have been in there, to raise a flag when it can't find the connection anymore...no?). Is there a way to know if the network connection drops? Is there a way to reconnect it? Is it just a matter of turning EnableRaisingEvents() off and back on to re-establish the link to the network share?

Is there anyway in vb.net to control this connection? So disconnect is and recconnect it etc?The reason for this is automatically getting a new ip address without manually disconnecting in network connections.

App Makes Live Calls To Our Network Over Wireless Connection

Nov 3, 2008

I am currently improving an existing handheld application, this app makes live calls to our network over the wireless connection, if the wireless connection is not established I am displaying a holding screen to the user, this screen rechecks connection every three seconds.I want to put a button on this screen that closes down the application if the user does not want to wait any longer. At the moment I am using the application.exit command, however it continues to finish the first original thread (i.e. trying to process the dataset) before actually closing the application, I am looking for a way to kill the application there and then!

Apr 2, 2010

I may be SOL on this but I thought I would give throw it out for possible solutions.I am writing a computer access control service tcontrol my kids' computer use. Plan on open sourcing it when I have it working. It is written in VB.Net and needs to work on XP through 7.I am running into all sorts of security and desktop access issues on Windows 7.The service needs to run as admin to execute the NetSh command to disable the network. But I cannot interact with the desktop from the service so I IPC to a UI to handle other stuff, but I still cannot detect from the service if the desktop is locked. Argghh!
