• JustinM Close_Wait

  Hi.. when i run netstat and see that a socket is in a Wait_Close state.. how long does it wait! and can u modify that time thnx CLOSE WAIT state is defined as: The device has received a close request ( FIN ) from the other device. It must now wait for the application on the local device to acknowledge this request and generate a matching request. Therefore, it is up to the local application on your machine to send a reciprocal FIN (ie. close its side of the TCP connection) in order for the connection to trasition past the CLOSEWAIT state in the TCP state machine. ...Show All

• AG Hunzian Visual Basic 2005 passing parameter to Oracle SQL

  Hi, I am using VS 2005, Oracle 9i, and have a question on passing a parameter to the query defined in a DataSet. All the examples I've seen use the use this syntax “ Select * From Customer Where CustomerId = @CustID” The problem I’m having is – I get an error on the @CustID. The SQL generator puts Quotes around it making it worthless. How do I do this Thanks VERY much, Carl From some ODBC programming I remember a syntax, where each parameter was just specified by a and you had to pass in parameters for such a call by adding them in the correct order. You may try that: "WHERE LASTNAME = ". Just a guess, might not work, though. -- SvenC In th ...Show All

• Koder021 I'm fairly certain I'm losing my mind....

  For the past 3 days, I've been spilling my brains all over my keyboard in an effort to do something that should be ridiculously simple.... What's really driving me crazy is the fact that I've done it before... Here it is: I have a datatable in MS Access. In an effort to copy all of it's records to a table in SQL that I can access and better manipulate, I created an SQL Database in my Visual Basic program and made a comparable SQL Table. I gave all the columns identical names and comparable data values as the columns in the Access table. Now, I just want to copy the records from the Access table directly into the new SQL table. Here's the catch. I'm doing all of this through the DESIGN interface because the last line of ...Show All

• &#169&#59; Ţĩмό Şąļσмāĸ Urgent: SslState throwing exception deep inside HttpRequest at random

  We have a class in our website that calls Fedex's web servers to receive quotes using an XML interface. (This is part of our check out processes). Over the past few days we've started receiving Disposed Object exceptions randomly during our HttpRequest. The class that is throwing the exception is actually in System.Net.Security.SslState, which is deep inside Microsoft's framework library and not called directly. We have never had problems like this before, nor can we find references to it on the Internet. Fedex recently upgraded their systems, but claims we have done something to break our code, whereas the only change we've made in recent weeks was moving from .NET 1.1 to .NET 2.0. We've been running on this code for over 2 years and hav ...Show All

• Thomas S. Andersen Using multiple SqlConnection objects, bad for performance?

  Hello, I am planning to use three databases on the local SQL Server. DB1 will be for App1, DB2 for App2, and DB3 will hold tables, that both, App1 and App2 need to access. With applications I mean ASP.NET applications. Obviously, I need in App1 and App2 at least two SqlConnection and SqlCommand objects, one that access their respective databases, and one that will access DB3. Will this result in a worse performance (The using of two SqlConnection objects in one aspx page as example, and switching them) Should I for better performance get rid of DB3 and add the tables there to DB1 and DB2 (Thus multiplying data, but, if the performance will be much better, it will be fine with me) I would be thankful for any advices. ...Show All

• Lu&#237&#59;s M. Costa Does it anyway that I can use .net 2.0 to generate an XML Excel Workbook

  Does it anyway that I can use .net 2.0 to generate an XML Excel Workbook. Does Microsoft have an object support for that If does, how If doesn't please show me the way. Thanks See also http://msdn.microsoft.com/office/tool/vsto/default.aspx . You can use XmlWriter to create any XML so it is possible to create an Excel XML with .NET 2.0. It however needs detailed knowledge of the Excel XML format (respectively the Office XML format as there are elements used in several namespaces). If Excel is installed then it might be easier to automate Excel to create a workbook and then save it in the Excel XML format. ...Show All

• ceedee How to map enumerated types in .Net WMI provider?

  I am trying to create a C#-based .Net WMI provider to instrument an application I am developing. Classes and events work well except I would like to have an event that provides a member which is an enumerated type. Example: public enum StatusList { Running, Paused, Stopped } [ InstrumentationClass ( InstrumentationType .Event)] public class StatusChange : System.Management.Instrumentation. BaseEvent { public StatusList Status; } It seems to me that WMI supports enumerated types because they appear in the server explorer. Also when I generate C# WMI classes using that class generator, I get enumerated types in those classes. When I run the code above, I get the following err ...Show All

• qrli Shutting down network computers?

  I suspect that I once again have someone leeching of my Wireless router again and I can't connect and lock it for some reason. So I thought perhaps I could shutdown the computer who is leeching off my network As a lesson :P There are probably a lot of software out there that could do this but it would be nice to learn how I could create such software. how exactly are you shutting them down I believe from the initial response I accidently forgot to add 2 backslashes extra since its an escape character in C# it should be: \\\\computername when using the shutdown util Error 1 The type or namespace name 'DirectoryServices' does not exist in the namespace 'System' (are you missing an assembl ...Show All
