Im trying to take fields from a Products Table and populate a listbox in a userform with the productName field. that works fine. but i also have to open the recordset and the connection. when i run the program, i get an error saying the 'operation is not allowed when the object is open' then it highlghts the bolded line in the following code:
Sub testc()
Dim SQL As String
SQL = "SELECT ProductID, ProductName, RetailPrice, QuantityOnHand " _
[Code]....
how can i get rid of the error? and what is the problem? i've tried closing the recordset in various places in different subs but nothing works. .
is the insert of my code to close a form and it happens to be that when i click on the close button it gives the error "Operation is not allowed when the object is closed"and highlights the adoPrimaryRS.Close() line.
I am using an ADODB connection to a Sybase ASE Database for a small app that runs queries and returns the results to a grid, to XML and to Schema file. I recently tried the query on a Sybase script (Between a Begin and End statement) and had an exception when I used RS.EOF which reported "Operation is not allowed when the object is closed." The code works fine for other queries, including those between begin and end statements, so I did some debugging and found that the failure only happens when my SQL script (Which is typed into a rich text box) contains either Sybase variables (ex. @MyTable) or uses temp tables (ex. Select * into #mytemptable from myrealtable). The actual execution works OK (without an exception) but the recordset seems to be closed. A failing example is :
Begin Declare @Name Varchar(30) Select @Name = "MY_TABLE"
I'm having difficulty using this code that the tutor has provided for me and have a strange error that only I appear to have. Below is a picture and my code... I have double checked my connection and reference and it all seems to be working fine. Whenever I click on a button within my application when i compile it the error below occurs.[code]...
Essentially every time I run my form it tells me that the operation is not allowed when the object is closed and it points towards my recordset. Below is my code in full (given to me by a teacher! not my own) and I wondered if you could tell me what the problem is. As I understand it there is another option to ADODB which is more appropriate for .net.
Code: Option Compare Text Public Class Form1 Private m_cnADOConnection As New ADODB.Connection
I'm very beginner in vb. I need to connect two forms with ms access. First form is connect with second using(form2.show). My need is when I execute the coding. I got a error on first form " An error occurred creating the form. See Exception.InnerException for details. The error is: Operation is not allowed when the object is closed.
I searched, I found another post, but didn't quite understand the answer... Here is what I am working with.I know the connection is good it does update it by 10 then give me the error...
I am using Visual Basic 6
Code: Private Sub Form_Load() Dim sql As String sql = "select * from Stats ORDER BY Hours" With ADO
I am getting an error "Operation is not allowed while object is closed". On this line of code "Do While myRecSet.EOF = False" here is all my code.

When I try to run my DLL in Autocad, I got the message below.Application attempted to perform an operation not allowed by the security policy. To grant this application the required permission, contact your.I know there are many threads on this error, but Im not sure about one thing.Can I resolved this on our FilesServer or I have to do something on each computers that will use the DLL ?
This error occurs when I want to add my app to the startup keys My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWAREMicrosoftWindowsCurrentVersionRun", True).SetValue(Application.ProductName, app)
I'm dabbling with writing a client/server app using sockets, for the first time. I've found some example code for a chat application which gives me some pointers, and I've got that working, but now I am trying to refactor the basic code (the example is all in embedded in forms) into classes but I'm running into difficulties. Basically I want a server application to listen for inbound messages with a general Listener object which will parse the message (which will include a reference so I can work out the address of the computer sending the message).
When a request comes in from a new computer it will create a new object containing (amongst other things) a new TCP connection back to the client for managing and returning messages.The problem is I'm getting the message "The operation is not allowed on non-connected sockets" in my refactored code.The original code (on a form with a single listbox and a background worker) looks liks this :
Imports System.Text Imports System.Net.Sockets Public Class Server
[code]....
I get the error on last line of code of the OnConnect procedure when my client application tries to connect. Now I know this worked fine with the original code but my new version of the code fails to set up the connection. I have removed the "background worker" stuff because as far as I can tell all it is doing is updating the display which I don't need to do.
I am working on a VB.NET project that grabs data from an Access DB file. All the code snipeets I have come across open the DB, do stuff and close it for each operation. I currently have the DB open for the entire time the application is running and only close it when the application exits.
My question is: Is there a benefit to opening the connection to the DB file for each operation instead of keeping it open for the duration the application is running?
I am trying to seek for a particular record and then delete it afterwards but somehow I get an error that says "Operation is not supported for this type of object". Of course the declaration are on top just below the "Public Class Form1"
declarations just below the public class from

During Loading of form I call connectpaybox to show the list in the combobox, but after that it will result in the error "Operation is not valid due the current state of the object"
but the combobox items that was taken from the database shows. I tried
"select CAGECOST from CAGETYPE where CAGENAME like 'Normal'" where Normal is one of the items in cagename and it works. Private Sub Paybox_Load(ByVal sender As System.Object, ByVal e As
Before, my codes are working properly.. But not..I am getting this run time error. What the error means? Operation is not valid due to the current state of the object.

I've written a VB.NET program for a client that stores all of its data in XML files. I use the XMLReader to read the data into a dataset. When I run the sub to encrypt the XML file, I'll get the following message: Error: mscorlib: The requested operation cannot be performed on a file with a user-mapped section open.
It doesn't happen all the time, so I know it does work. But on occassion, I'll get this message. I've been all over the forums and I've tried everything I've read to try and stop this error.
I close the reader object and set it equal to Nothing. I've even tried using DoEvents to make sure the object finished closing before running the Encrypt sub. Nothing has helped.
I develop on a x32 PC. It works fine on the development machine. But then, when the client runs it on a x64 PC, he gets these errors. Could the x64 system really be running so fast that the .Close() and the = Nothing and evern the .DoEvents() can't keep up?

However, it fails when trying to open the registry hive with an "Attempted to perform an unauthorized operation" error.I know the password is correct so can someone tell me what might be going wrong?
i want to have some web browsers which navigate wile the thread is running and my problem is that I want to use a web browser object from .net in a thread. when i put a webbrowser object in my form, called webbrowser1, i cant reach it in the thread's operation(start thread). when i type webbroeser1 in the thread it doesn't undrestand what webbrowser1 is.
This is just a general question, I need help with something on Visual Basic 2008. I do not know why, but as of late every time I open up a project in Vb it gives me something called an object browser. I try to find my forms so I can work on my program, but I can't find them. Has anyone else had this problem or knows how to fix it? I can't get to my forms!!
I'd like to know if it possible to show HTML page created in VB using WebBrowser object without using files on disk.That is, create HTML file in memory and show it within WebBrowser object.
