Operation Is Not Allowed When The Object Is Closed?

Sep 23, 2009

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"

Operation Is Not Allowed When The Object Is Closed ADODB?

May 10, 2012

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

VS 2008 "The Operation Is Not Allowed On Non-connected Sockets"

Apr 6, 2009

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 get this error on the server. I cannot replicate this on my development machine.I get it when i call ExecuteReader, ExecuteScalar or when i try to fill a dataset.I use an oracle database.This, i think, increases when the load on the server increases. Im not sure.i need help fixing this. Please let me know if you need anymore details.The code for ExecuteScalar would be as follows

Remaking Com Object After Program Closed

Dec 2, 2010

What makes it even harder is that I can't replicate this problem on my computer very consistently. Sometimes I will get the error but most of the time I won't. Basically what is happening is I am creating an IE object which my program then controls for a long period of time. What is happening is, if a user exits the program it calls oIE.Quit() then closes the program. This should close internet explorer and all processes associated with it.

But, the iexplorer process doesn't end up closing. Then when the user tries to run the program again we get this error "System.Runtime.InteropServices.COMException (0x80004005): Creating an instance of the COM component with CLSID {0002DF01-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error: 80004005.".

To fix this we simply close the any iexplorer.exe processes that are open and it will let us create our i.e. object again. This happens also if the program crashes and they try to restart it. I am not sure what is causing this or if I am missing something that has to do with com objects. Here is some code although plugging in this code likely won't reproduce any errors:

'create ie object
oIE = New SHDocVw.InternetExplorer
oIE.Navigate("[URL]")
oIE.Visible = False
oIE.Silent = True
'kill ie object
oIE.Quit()

.net - DataReader Not Closed When Connection Is Closed, Consequences?

May 31, 2011

for example i have this code :

Sub Month()
Dim Conn As New Data.OracleClient.OracleConnection
Conn.Open()
Try
Dim Cmd As New Data.OracleClient.OracleCommand
With Cmd

[Code]...

What will happen to the datareader when the Connection is closed ( Conn.close)

Will the Cursor that is used by the datareader be freed ? or will it stay open ?

If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?

Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?

VS 2008 Method Not Allowed When Using Proxy Support For A Webrequest?

Mar 13, 2010

I am trying to post data to a form on my website. This works perfect.To expand off for personal use and education, I decided to try and add proxy support. I got a list of some proxies, and did it up. The proxies work, and all is good. But, when I try this with this specific example, I receive 1 of 2 errors depending on the proxy used.(405) Method Not Allowed or (500) Internal Server Error.I realize that both of these are being caused from the proxy side of things, but maybe theres an issue with my code?

Delphi combines the two substrings, while .Net just concatenate them like a copy.

VS 2008 - Build Must Be Stopped Before Solution Can Be Closed

May 20, 2011

When the Visual Basic compiler (Vbc.exe) crashes, Visual Studio fails to detect this and becomes stuck in an inoperable state. The "Build" menu appears as it would if the solution were building, but the Cancel Build (Ctrl+Break) menu item has no effect. Trying to close the application or the solution gives the error:
"The build must be stopped before the solution can be closed."
I can't find any way to remedy this short of terminating the devenv.exe process and restarting Visual Studio completely. Is there anything quicker and less severe?

VS 2008 Form Will Not Release Connection When Closed?

Apr 26, 2010

I have a form that contains a crystal report viewer. When I open this form, it runs a report. I am using a .LDB viewer to tell who is logged into an access database. I noticed that when this form opens, the computer logs into the database and stays logged in. Even when the form is closed, the computer is listed as "logged in". If I run the report again, it just adds another instance of that same computer logged in. Therefore, it continues to pile up logins until the application is closed.
