"Unexpected Error" When Trying To Connect To Add Data Source?
Feb 25, 2009
When trying to add a new data source (connect to database with .mdf extension stored on my computer)verything goes well until I get to he step giving me the option to save the connection string, then I get the following error message: "An unexpected error has occurred. Error message: Could not load type 'Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager' from assembly'Microsoft.VisualStudio.DataDesign.SyncDesigner.DslPackage, Version=9.0.0.0, Culture=neutral,PublicKeyToken=b03f5f711d5013a'. I am taking a course online in Advanced Visual Basic and most of it involves working with databases. If I cannot get past this error, I cannot do any of theassignments. I am using the free 90 day download of Visual Studio 2008 and will buy it before trial expires, but only if it starts working and stops generating error messages
I'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
I need a connection string for connecting database. I have already used the connection string following. connStr= "Provider=MSDASQL;Driver={Microsoft Access Driver (*.mdb)};DBQ=c:\mydb.mdb;Data Source=SampleDSN"; But, I got error as "Data source not found and no default driver specified". [URL]
I have a windows service written in .NET 2.0 that will run every 5 minutes and executes bunch oracle SQL/PLSQL scripts based on time/validation, it throws the above said error some times against some SQLs, the same SQLs run fine at later point without any error, I have no idea what is going on with the app. I am not sure if this has any thing to do with oracle connection pool as I am properly closing the connections after every SQL execution.
Exception:
System.Exception: Unexpected return code: 1 at System.Data.OracleClient.DBObjectPool.GetObject(Object owningObject, Boolean& isInTransaction) at System.Data.OracleClient.OracleConnectionPoolManager.GetPooledConnection(String encryptedConnectionString,
I built a database from an .sql script file in Microsoft SQL Server 2008 Express Management Studio.Now, I need to connect an application I'm developing to this database. So in Visual Basic 2008 Express (that's what I use) I go to:
Data-->Add New Data Source-->Database-->New Connection In the dialog which pops up (name: Add Connection) I set: Data Source = Microsoft SQL Server Database File

In duplicated code using Lockbits in VB to obtain the address of Bitmap.Scan0, the first is OK, in all applications, but the second NEVER is. What is the explanation please? Surely both StartAddrA and StartAddrB should be valid pointers to Bitmap.Scan0 for calls to valid, functional ASM code in the functional DLL. The error is, it seems, in the VB Lockbits process. Using VS2010 Beta 2 and XP.
In this line of code ".lim" is underlined and the error is that an End Of statement is expected,i wrote End Of at the end of teh code and the error did not dissappear.

Ok so i have a date time picker that holds a date that was entered by a user. My program works fine when ran on a computer using English(US) regional settings, but when i take it to a computer running any other regional settings, I.E. English(UK), which is the 2nd most common regional settings that will find its way to this program, I recieve an error because the Date format is backwards. What i'm curious about is how can i grab the system Regional Date format in order to rearrange my Date to fix its context?
I know that since the date is stored as a string i'm going to do something along the lines of this to break it apart:
We have an application (Vb6) that gets installed at all of our client sites and they often (Vista/Windows 7) run into a the error message Unexpected error, quiting after a install on a new machine. The problem comes about when the UAC is on and the application is trying to create registry entries in areas it doesnt have access to because the application is running as a standard user. If the user runs the application as an admin the first time, everything sets up and life if good.
My question is, what is the most elegant way to setup those registry keys without forcing the user to run as an admin the first time? We could force them to run the applicaiton as an admin using a manifest file, but I dont want them to have to run as an admin every time, just the first time.
I am trying to open/read excel (2003) file in vb.net but I m keep getting "Unexpected error from external database driver (22)". I have also tried SSIS but same error pops up. I have used following connection strings but none of them seem to be working:

I am reading a large number of XML files and do not want my program to bomb on exceptions. I am making great strides in reporting the errors, skipping the offending files and continuing the import process. However I am having problems with XmlExceptions. I get the following XmlException on the While textReader.Read() line of my program:
Quote:
XmlException was unhandled Unexpected end of file has occurred. The following elements are not closed: my:PicInsert, my:PictureGroup, my:myFields. Line 153, position 430817.
I am finding some of the reasons why, missing tags etc, but those aren't really my concern. I just want to report the issue and continue. I am thinking about some kind of check for a valid xml file but fear that that might not catch it all. For example I had a image tag in one of the files that was missing an alt="" attribute and I am not sure if that would invalidate the entire XML file.What would be the best way to trap and deal with the exception with out causing interuption to the program?
OS: Win7 64bits Software Tools:Package and Deployment Wizard (for VB6.0)The vbp file is working in XP. Installed the VB6.0 in Win7 64bits, it can make the exe file.However, the setup file can be made using the 'Package and Deployment Wizard' Tool.
In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True } ChildForm.Show Me.Hide()
[Code].....
Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?
I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
I'm creating a program (Which will eventually be a service) which loops a section of code which downloads files from a variety of FTP servers.All files are succesfully downloaded on the first iteration, however after this the download fails with the following error..."The underlying connection was closed: An unexpected error occurred on a receive."Curiously, the error does not occur if the loop only downloads the same file from the same Ftp server. It only occurs when 2 or more files are downloaded.I use the following code...
Dim fwr As FtpWebRequest = CType(FtpWebRequest.Create(Supplier.FTP_Address & Supplier.FilePath & Supplier.FromFile), FtpWebRequest) 'Set credentials fwr.Credentials = New NetworkCredential(Supplier.Username, Supplier.Password)
I am building a client in VB.net for calling webservices methods from a partner organisation.[URL]../system.web.services.protocols.soaphttpclientprotocol%28v=VS.71%29.aspx because I can't get it to work using the Web References feature of Visual Studio 2010 (when I try to do that it turns the methods from the WSDL into classes).I have created a proxy class and can instantiate an object of that class no problem.
However, when I try to call a method which requires arguments I get this error:
Unmarshalling Error: unexpected element (uri:"http://api.service.apimember.emailvision.com/", local:"key"). Expected elements are <{}key>,<{}login>,<{}pwd> Does anyone have any idea why this might be? (If it's helpful I can post my code and the location of the WSDL.) (P.S. I can get the whole thing to work fine in PHP using ZF Soap classes, but for various reasons I need to get it to work using .Net)
Edit to add: I have used Wireshark to examine the outgoing and incoming SOAP message to compare them with the messages being sent via SoapUI, where it all works fine.What this has shown is that my VB client is sending a message where the namespace of the web service I am trying to access is declared as an attribute of the method, and not in the soap:envelope attributes.
I have a VB.NET WinForms application. While adding a new data source, it is giving "An item with the same already been added" on the Add Data Source wizard form.
The application does not contains any existing data source.
What could possibly be causing this error, and how might I go about resolving it?
My application using Ms Access DB. when i connect to DB from client machine it show error at conn.open. the error was "you need permission to view its data".If I login to the server, it works perfectly.
[code]...
Is there any way to access the DB from code without server login?
