If i do direct(without Step by step), it is rasing this error as "Unspecified error", Particualr time all the recordsets are closed. But on the same project, opening lot of recordsets,closing and set as nothing. After somtimes only i am getting this error. Why i am getting this error really confusing?
View 2 RepliesI am using VS 2008 Professional and connecting to an Access 2003 database.I have converted my app from VS 2003 to VS 2008.I have kept all the OleDbDataAdpaters.When designing,I like to have both VS and Access open, so I can see if my SQL queries and other code load/ edit/ append/delete the data correctly.The problem I am having, is once I open Access, I can no longer edit any of my database settings in VS. Examples:In VS I open the Server Explorer, and see the database I am using.I double click on it, and I get the error message "Unspecified Error".In VS I try to add a DataSource.In the Data Source Configuration Window, in the Choose a Data Source Type pane, I select Database and click on Next.When I see Choose Your Data Connection, I select my database, and I get "Failed to open a connection to the database "Unspecified Error" Check the connection and try again."In VS I try to configure the OleDbDataAdpater, I right click on it and get the Data Adapter Configuration Wizard window, in the Choose your Data Connection pane, I select my database, and I get "Failed to open a connection to the database "Unspecified Error" Check the connection and try again."If I run/debug my app, the data loads just fine. So I know the data is not messed up, and the connection is OK. I just have problems when I am designing in VS 2008 and after I have opened Access 2003. If I close Access, the problem does not go away. To get the problem to go away, I need to : close Access,close VS, open VS,load a new project,Add a new Data Source to the new project,re-open my project.What is happening? Is there a better way to "reset" VS ?

Now I am trying to publish another form which has a connection to my sql database. The publishing goes fine: publishing folder is: C:Movie-databaseApplication 4 and installation folder is the same, and I therefore leave it empty. Application is available only online.

When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]

I want to add a List(Of Book) property to my user control. I defined a Book class and BookCollectionEditor class for CollectionEditor. And also I defined a public property named BookList for my user control. For a custom control it works fine but for user control, the designer does not display my property. On markup I can add a Book item but on designer it gives error: "Type 'System.Web.UI.UserControl' does not have a public property named 'BookList'."Isn't is possible to define a list property for a user control?

View 1 RepliesI was googling / searching the forums for this type of code.I want to be able create a folder within my application folder, mainly because I don't want people using my program to use a specified path to be able to use my program.
Example,If I would using a specified path It would be ("C:/Macbrutal/Foldername")And the user who would install my application surely, doesn't have macbrutal as username for windows so their path would be ("C:/User/Foldername") and that would bring my program an error, if you get me.
So to brake it down a little, Let's say my path for my program is ("C:/Macbrutal") I want my program to generate a folder where my application is located (not with specified path) which would be (C:/Macbrutal/newfolder")

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.
