View 11 RepliesI'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 am wondering if anyone else has experienced any issues with adding a data source to a VB.NET 2010 solution using the 'Add New Data Source' wizard. I am getting a very odd behavior when i add the data source, I see a .xsd file is added in my solution explorer but I do not get a data source listed in the data source view. In short, it will add a dataset to the project but will not add an entry in the project data sources. I realize I can code to get the same results but purely out of convenience I would much prefer to just use the wizard and the corresponding table adapters it generates as I always did.
By the way, a google search shows that many people had similar issues in the 2005 version but their issues involved trying to use special characters in the project path (i.e. 'C:My ProjectsR & DMy Tool. I do not use any special characters in my project paths and yet am still experiencing this issue.
I will start off here by asking the question. How do I make the data from a database be bound to my project? I keep trying to add a new data source so that I can drag and drop things to my form, but I am unable to. I follow the steps, choosing an OLE DB, the file's location (D:Data Connected Applicationsfile name) The conecting string looks like: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="D:Data Connected ApplicationsItem_Database_A.accdb". I choose the objects that I want (In this case, the entire tables option) and then it returns a message to me stating that: An error occurred while creating the new data source: Could not get information for 'WindowsApplication1.Item_Database_A.accdbDataSet3'

1. I have a DataGridView box, that is connected to a MySQL database via the 'Data Source'. I am trying to do the datagridview1.rows.add("info here"), however i receive an error i cannot do this programmatically. I DO know the code to post to MySQL via the "insert into" la la la.However, I was curious if I can do this via the datagridview a bit..easier/simpler, such as a "datagridview1.rows.add(stuff)" sorta thing.
2. I am attempting to make a custom control, and as with ANY control, they have their.. settings. Example, a textbox, or label, has so you can set the Text. and color, etc.Others, have it (such as datagridview) have the little icon on the control itself, where you click it, and it opens a small window with settings.
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?
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.
View 4 RepliesI have an Access database and I want to view on a datagridview specific rows. For that I used the following :
CasesBindingSource.Filter =
"OfferDate Between #1/1/1997# And #12/31/1997#"
Cases is the table, OfferDate a field of the table wich is DateTime type.
When I use Between operator I get the following error :The expression contains unsupported operator 'Between'.
I'm currently working on a project where I want to ensure a user does not create a new record based on an ID (such as Customer ID) that already exists.If the record does exist, don;t create the new record and simply move the bidning source to the existing record and display that.What I'm currently doing within the Binding Navigator Add New Click event is checking if there is current data to save and prompting the user if they wish to save the changes before doing anything else.I then set a boolean variable called _NewRecord to true. Then within the lost focus event of the record ID, I have the following code:
Dim itemFound = -1
If _NewRecord Then
itemFound = GroupExists(txtGroupID.Text)[code]....
The code above works well, but I was thinking of doing this using the AddingNew event of the binding source instead to check for an existing record and simply cancel the new record addition then move to the existing record. However, I couldn't find any good examples of how I might do that or how to properly use the AddingNew event.good example of using the AddingNew Method as it looks like it might be useful to know for future projects.
I am using a For Each Next type loop to read a records from a datatable and add records to a second table.Under certain circumstances, I add one or more records to the first table that I want to process.The problem is that the added record is not in the original datatable.The For Each...Next loop goes dutifully until the datatable records are processed, but the added record(s) do no get processed.How can I "refresh" the datatable and process the added records?

View 2 Replieshow 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.
I 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"

can data reader be used as a data source for a grid control?
View 5 RepliesI 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.

I'm creating a gridview using an objectdatasource and it works fine when pulling all records. But when I want to use the selectCountMethod the grid shows no values. I Step through the code and my getInvoices (gets the requested data) returns data and the getInvoicesCount (gets the total record count). 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. Any reasons why it wouldn't work or something special that needs to be done for getting the selectcount to work? [code]
