How to resolve this problem?

Code Runs When Debugging But Stalls In Run Mode?

i wrote a piece of code to write some data to a card reader, and read back from that device, filling a form with the data (after reformat).When I step through the code while debugging (using F5, F8 for stepping forward) the form is filled correctly.However, when I run the code (Ctrl-F5), the program seems to hang for about 5 sec and then throws an exception: 'Length should be >0' When looking further during debug - it seems that the program calls 2x the Sub Frm_Read_Display().

Disconnected And Connected Feature Of ADO.NET

May 19, 2010

I just read a book : Pro ADO.NET 2.0.It discuss about the disconnected and connected feature of the ADO.NET.In disconnected, the "data container" is DataSet.But it doesn't say anything about the data container if i use the connected feature. In ADO, we have recordset, what about ADO.NET.

Handle When COM Object Is Disconnected From RCW?

Feb 15, 2012

Is there any way to run code when COM object is about to be disconnected from RCW without implementing IDisposale interface and explicit call MyObject.Dispose in client code?

The code below is not working. When program enters Finalize sub, ExcelApplication is already disconnected from RCW, and I get error. I understand why it happens, but I want to get a solution.

I want to make it working the following way: when last managed reference is released, code from Finalize sub is executed before COM object is disconnected.

My question is - is it possible at all and if it is then how can I handle this event inside the class, without need to call Finalize explicitly from outside?

Very simple class:

Public Class ExcelRunner
Dim ExcelApplication As Excel.Application
Public Sub New()

C# - Deploying App To Production Using Debug Mode Rather Than Release Mode?

Oct 28, 2010

I work for a shop that maintains a fairly new app. The app still has its fair share of bugs, with numerous tickets coming in daily. The error information we're given with those tickets is not as useful as it might be because the application was compiled in Release mode, which I read is smaller and faster (makes sense).

Are there any ramifications to deploying a .NET application to production that was compiled in Debug mode? I would expect it would be a bit slower, but I've read the difference is nominal. This would assure us that when we get errors on tickets we have line number associated with those errors and this, of course, makes debugging much easier. major red flags that would prevent you from doing this? I'm tasked with researching the possibility.

Network Connections Disconnected After Launching .NET App?

Feb 17, 2011

I shipped a VB .NET app to my customer. They installed the app in program files folder. The app starts and everything works ok. Now my customer reports that some intranet TCP/IP connections are interrupted after starting the app. Sometimes they are not available after starting my app, sometimes the intranet connections are still available after my app has been started. After my app has been started, there are connection error messages to their intranet services. After re-starting the machine, they still can't connect to the intranet services. A fix is to login with another user name or re-load the profile from the server after they have been logged in on another machine.

Do you have any ideas where to start further investigations? Is it possible that my .NET app interrupts or blocks intranet connections? Could you recommend any trace tool that gives me a hint when and why the intranet connections are blocked? Why could it work for them after they login on another machine?I am wondering if my .NET app could disable the intranet connections. Do you have any recommendation for testing that?

Create An ADODB Disconnected Recordset In Windows Application?

Sep 2, 2011

I'm using an OLEDB connection to a Sybase database, with ADODB.dll file version 7.10.6070.0 (which comes from the Sybase 12.5 package). I need to be able to open a connection, use a command object to fill a recordset from a stored procedure, then close the connection and pass back a disconnected recordset. My attempts so far fail as every time I close the connection, my recordset also closes (which means it is not disconnected).

Is there a property I must set somewhere to indicate that the recordset should be disconnected? I cannot set Recordset.ActiveConnection = False because I get an exception ("Cannot change the ActiveConnection property of a Recordset object which has a Command object as its source."). I do set the Command.ActiveConnection = False, but that doesn't stop the recordset from closing as soon as I close the connection object.[code]...

VS 2008 - Respond To PING Request Disconnected From Irc Server With "Excess Flood"

Jul 13, 2009

I found an example of a simple irc client, but I'm really confused about how it sends data back to the irc server. In the example, this is the code used to respond to the server's PING request. it lies in the onDataArrival event of a sockets client:[Code]

However with this simplified code, as soon as it tries to respond to the PING request it is disconnected from the irc server with the reason "Excess Flood". So I was hoping someone could explain to me the difference between the pretty complicated method and my simplified one which doesn't work.

Unable To Close Serial Port After USB / Serial Converter Disconnected

Mar 28, 2006

I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.

When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

Add / Edit Mode For Forms?

Sep 10, 2010

When in "Add" mode, I have all controls on the form enabled with the exception of a listview that is disabled until the record is saved. The listview needs the primary key from the saved record in order for items to be added to the listview.

When in "Edit" mode, the form is populated when a record is selected on a search form. Specific controls are disabled. When a value in a control is changed, I have a RecordModified property that is set to True and then the Save button is enabled. I also have combo boxes that need to be populated but the selected value needs to correspond to the value pulled from the database

Changes Don't Work In Debug Mode?

Whenever I make any changes in my project, they don't work and aren't visible in debug mode. They are all visible in my designer mode. It's the same with newly added code, it just doesn't work (even a simple command like showing a test messagebox doesn't work).

How could this be? It all worked fine until recently. I don't want to start over with my project, because it's a pretty big one.
