I am running my application and at random times when it is unable to connect to the database I get an error saying "A Transport-level error has occurred when receiving results from the server.

A transport-level error has occurred when sending the request to the server.

I am working on a project using VS2010 SQL2008 and I saw an ODD behaviour , First let me tell you that the app runs without any problem in my developing pc (Windows Xp sp3 32bit)But when I was trying the application in another pc (Windows 7 32bit)I got this exception: A network-related or instance-specific error occured while establishing a connection to SQL server.The server was not found or was not accessible.Verfiy that the instance name is correct and that SQl server is configured to allow remote connections.
Now what is weird in this exception; Is when the application reaches the DataAdpater.Fill(dataset) line I got this exception but when the app reaches the DataAdpter.Insert(....) It runs without any problem .
And what is more weird is that I noticed that the dataset that is used in the previous insert procedure can later be filled with dataAdapter.Fill(...) procedure which it was giving me an exception before .
I tried these things as a solution:
1)Checked SQlBrowser running..
2)No aliases to Sql server at all to remove...
3)remote area connection--OK
4)TCP and UDP port 1433,1434 exception in firewall
5)Unistalled my only antivirus Norton
6)Added Tcp/IP ports in Sql protocols
7)My connection String is : onnectionString="Data Source=ALISQLEXPRESS;Initial Catalog=PALMSDATABASE;Integrated Security=True"
8)Also tried using Sql Server authentication (user Id and password)
what is the difference between fill and insert? My app. runs smoothly on the original pc ,What should I do?

View 1 RepliesI got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

I'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
