IDE :: Data Source Disappeared - Recreate My Data Source From The Entry That Is In App?
Feb 10, 2012I 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.

View 2 RepliesConnect A VB Application To An MS Access DB By Adding A Data Source From The Data Menu?
Jul 7, 2011I'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
How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done
Apr 23, 2010how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
Multiple Combo Boxes Showing Data From The Same Data Source?
May 10, 2010I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

View 5 RepliesAccess Other Data Fields From Combo Box Data Source?
Nov 4, 2009I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

Getting Data From A Data Source Using Binding Sources?
Aug 14, 2009I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that. If I use the data visualizer I can see the name I am after, I cannot figure out the call to extract it

But then when I go through the rowdatabound of the gridview there's nothing in there and no data displays. Here is my code to set the objectdatasource.

View 1 RepliesIDE :: Project Currently Has No Data Source Associated With It?
Feb 11, 2010I have purchased and installed the EBook "Visual Basic 2008 Step By Step". The package comes with a companion CD on which are practice projects that correspond to the book. I have installed Visual Basic Express 2008 and also installed the "Practice Files" exactly as required. When I enter the VB 2008 Express IDE and attempt to load the project or solution files, the program loads and I get no error. The problem is that I get no data when this happens. The "Data Source" box displays a message that reads, "Your project currently has no data sources associated with it. Add a new data source, then data-bind items by dragging from this window onto forms or existing controls." The files did load properly for me once, but have not ever since. Does anybody have any clue as to what needs to be done here?

Aug 9, 2009I'm making a program that permits a user to connect to a database. I'm using the "data source" section of visual studio. How can I allow the user to specify the path of the database?
I can forsee a problem: the user could specify a database that doesn't have the same schema than the one used in the visual studio environment. But it is not a concern to me to only prompt an error.
Any idea how can I let teh user choses its DB? Can I edit the connection string in the datasource maybe?
VS 2010 Add New Data Source?
Dec 29, 2011Most of the VB.net windows application I have created so far have been working off a local server. To add a data source I click Add New Data Source and then database and then connect to the database by linking through an ODBC driver. This works neatly and places data sets that I can then pull onto forms in various formats, DGV's textbox, Combobox etc.
The application I am trying to build now links to a hosted server on the internet. For security reasons I cannot create an ODBC that connects to the database. I can use a ADO connection string and this is fine for various tasks and I know I can populate a DGV using this connection. However, it is much quicker once I have dataset that I can repeatley call on.
What Should Choose For Source Of Data
Sep 11, 2011In our class in Visual Basic, we are required to turn in a payroll system with time monitoring. And I have prepared already the GUI interface of my system. My question is what kind of collection of data should I use, considering the employee population of 30 (that's what our instructor have told us.)Should I use:
a. Arrays to store them like every field (employee number, employee last name, etc.) has its own array.
b. Sequential files for me to store them in a text file (and if in the text file, could I still retrieve the records inside that text file.)
c. A Database.
