I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...
We have an in-house developed VB.Net Windows Forms application that is losing users' individual connections to the SQL Server 2008 R2 database.The bolded message below is what appears.
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)I have looked at many numerous articles both from Microsoft and others, but have been unable to pinpoint the issue.Sometimes it occurs when the user has been away from the open application for a long-time; others maybe less than 20 minutes.
login.aspx generates the following error on load, this file worked great for over 2 years, problems with Godaddy forced us to create a new account IIS6 ASP 1.1 which matched the original hosting environment. However now after the migration this file generates this error. Any Ideas why this parsing error is generated?

View 7 RepliesI am looking for a great VB.NET forum for support on the newest 2010 version.
I have a large project currently Compiled on the NET 4.0.
I have also ran it on 3.4, 2.0, and, 1.1..
I am trying to read a text file on a server which has ONE line about 12 charters long.
On the initial request to read the file I have about a 7 second delay before there is any further action. All subsequent request are instant considering I do not close the program.
I have searched and searched Google and read some older post from this site. Most refer to the proxy setting and say setting the proxy to NULL will fix this issue. Well we all know that this cannot be down in the newer version of .NET. I did not have this issue in .NET 1.1 using the same code.
Can anyone here tell me how to make the webclient avoid this delay the first time it hits the server?[code]...
