• .NET Development SocketConnection error in Async call when network drops

  Hi all, I have an asynchronous web-service call happening in the background of my application just after it starts. If my device (I'm running on a Windows Mobile 2003 device) drops off the network (I move out of wi-fi range) the application crashes with a SocketException. The error is something like:    An operation was attempted on something that is not a socket    at Socket.Poll()    at Connection.Read()    ... Obviously the async call to my webmethod is failing because the network connection is not there any more. What can I do about it How do I handle exceptions from async web s ...Show All

• Visual C++ Atlthunk.lib help.

  I'm using Visual C++ 2005 Express with SAPI 5.1. I managed to fix the header file compilation errors, except that atlthunk.lib does not exist. Is my solution the same as with using WTL with Visual C++ 2005 Express (I'm referring to the site here .) Yes it is. The page you mentioned describes how to entirely remove the need for atlthunk.lib. That's what providing definitions for AllocStdCallThunk and FreeStdCallThunk does for you. ...Show All

• SQL Server What happened to good old object search ???

  Hi There I have been working with MSS Management Studio for some time now. One thing really bothers me, i cannot find the equivalent for object search found in good old query analyser. I have many QA databases, and the all have tens of thousands of tables and views. If i need to find a table or view i go to query analyser and do an object search and i get the result within a second. The only thing i can do in Management Studion is filter the views or tables for the one i am looking for , problem is with the number of objects in these databases i can go for a smoke and come back before i get results.

  Anybody either have some good tips, or point me to some sources with good tips for avoiding problems with header file includes when classes reference each other, i.e. class A has a member variable (or reference or pointer to B) and B has a member variable (or reference or pointer to A) Forward declaration tips would also be welcome!

• Windows Forms Inherited Click handler

  I have an MDI application in which all of the child forms inherit from a base form. This base form handles all of the common functionality of the child forms, including form initialization and closing logic. I have a protected method called CloseButton_Click which is supposed to be the Click handler for any button on a derived form which closes the form when it is clicked (primarily OK and Cancel buttons, but there a few other cases as well). The method sets the DialogResult of the form to the DialogResult of the button, and then closes the form (similar to the functionality of modal forms, but my forms are not modal). However, when I look a ...Show All

• SQL Server DTC Transaction Abort error

  We are using MSDTC to handle our transactions and some clients seem to be getting these errors more and more when we went to framework 2.0. Any ideas what could be causing this Before in framework 1.1 we would ask our clients to re-register their computer into the domain and/or rename their computer and this worked but it seems like in framework 2.0 it doesn't do the trick. Also, the wrong dns setup causes this too but after trying to fix both things it still doesn't work. I believe this error means either the server has finished the transaction and can't find the client to return the result or the active directory account/computer accoun ...Show All
