I´m trying to update the database i´ve already have de data set BDHERGAIMDataSet with all my tables(tbboletines is one of them) i add a new row, and set the values of each column of the row in the table and then try to update the database.It doesn´t give me any errors when I run it but it doesn´t write nothing on the database table....
Dim newvobol As BDHERGAIMDataSet.tbboletinesRow
newvobol =Me.BDHERGAIMDataSet.tbboletines.NewtbboletinesRow
newvobol.idnaturaleza = 1
AddNodesTableRows As SampleDatabaseDataSet.NodesRow Dim i As Integer For i = 0 To 10 AddNodesTableRows = SampleDatabaseDataSet.Nodes.NewNodesRow()
[code]....
End Try I've get no errors or exceptions from this code but it will not put the data into the database file. It always run through the "update successfull" yet nothing is ever written out to the file.
I'm using TableAdapters in VB.NET (VS2008) to an SQLCE DB. These are associated with a range of DataTables in my DataSet.
I'm trying to simplify my app and I'm wondering : If I call the Update method of a table adapter and there have been no changes, then will the TableAdapter still open the underlying database, or is it smart enough not to bother?
At present I'm using simple boolean flags to keep track of which DataTables have modified data - and it works fine - but I'm just thinking I might be able to simplify my code just by always letting it call the updates. But I only want to do if it won't add an overhead.
I have a form that has a datagrid thats being filled by data from a temporary database (called Scratchpad3) and what I'm needing to do is to update another table that's not part being called with my table adapter. My table adapter looks as follows:
I have a VB windows Form project that connects to several DataTables in an Access DB. On my form I have several textboxes, comboboxes and datetimepickers that are bound to those sources. With one table in particular when I try to update the tableadapter after editing one of the textboxes the update method fails. No exceptions are thrown, but the update method returns a zero value and the data is not updated. The update will work when just the comboboxes or datetimepickers are edited, but as soon as a textbox is edited also, update will not work.
Other DataTables within the project are set up in the same manner but are not having update issues. I can't figure out what about this one particular table is causing an issue. Can anyone give me any thoughts on where or what to troubleshoot?
In VS STUDIO 2008 I have made a datagrid , where i have set yes too edith, new and delete.this works fine, but now i need some code in form closing to Update my tableadapter to the value from my datagrid
Yes i know there are many Question about this i have read and read this answers but i Can't fine out how to make yhis to work

Environment = VB.NET 2005 & Pervasive SQL 9.5 ADO.NET In a simplified example, I have single database table (customers) with the columns "customer_code_PK" and "customer_name" This table is presented in VB.NET 2005 as a single form datagrid (bindingsource/dataset). In this example, the database table is populated with the following data
how would i go about resetting or refreshing a table adapter before it fills a data grid view (load event). As i have tried a number of things to get it to refresh but it seems that the data connection to the Database is simply not closing and re- openingwould i have to program it to be a manual thing to retrieve the data from the database or am i just not doing it right

I have a TableAdapter I created in the DataSet designer. It contains joined tables and I set it up to automatically generate Insert/Update/Delete commands. I understand that I have to write my own UpdateCommand. I did so, in the DataSet Designer, for this particular TableAdapter.
The issue is that the Update Method is not showing up via IntelliSense, when I attempt to write code like this:
vb.net Dim x as Integer = Me.DPTableAdapter.Update(), IntelliSense does not show the Update Method with the parameters I set up.I created the same exact method with another TableAdapter, in the same manner, and it worked just fine.
I also call EndEdit on the BindingSource, I just did not put it in this post.
I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).
Whenever I create a table adpater the wizard does not create and update command. It creates Select Insert and Delete but no Update command. I have a primary key in the data and have completely deleted my dataset and created connection and table adtaer from scratch with still no update command wizard says it will create it but does not.
I need your support here. I have one dataset with numerous table adapters in one project. All fine. Now, in another project I am referencing the same dataset. I have added it as a link.So far so good. However, when I change a tableadapter in my main project store and close, and then open my other project the changes to the tableadapter are not there. For example, I have been adding an additional field to an adapter. But when running the second project that field is not part of the tableadapter.
After investigating a bit, I can say that, for whatever reason, when I link the datasets XSD file it created a copy of the respective Designer File. There is now a link to FundResultContainer.designer.vb, as a child of FundResultContainer.vb. But there is also a FundResultContainer1.Designer.vb as a child of FundResultContainer.xsd.
This could be causing my problem. However, to clean it up, I have removed the whole tree (dataset) and linked only the XSD file again. IT does again create a second designer file, exactly as above.
The program I have created will ping 4,000 ip addresses--each on a different thread. If the ping comes back successful, then it will update a database with its IP address.I get an error message saying "Could not update; currently locked" after about 30 seconds of updating the database.
I have to work in two parallel environments, developement and production, I want to use the same TableAdapter to connect to different databases (two Oracle databases running on different servers) with the very same structure. How is this possible?
I've been struggling the entire day trying to figure this out. Basically the data in my form won't save to the tableAdapter. To update the database I use:
The database was created using SSMS 2008 R2 and I'm using VS 2010.
I have confirmed that the data is being stored in the data row (because when I removed data from the data row it wouldn't accept because there are NOT NULL columns) and I have followed the instructions of this form as well:[URl]..
Created dataset with tableadapter.Dragged dataset and tableadapter to the form so I can reference it in code.New records successfully add to the dataset but will not commit back to the database.Gives no error or clue why it won't work.TableAdapter insert statement was created automatically and is parameterized (@p1, @p2, etc.), but I am trying to avoid those parameter.add statements as I want to be able to use a field-by-field format without having to essentially repeat the schema of my database in code with parameter.add statements.Command object and INSERT statements work fine, but then you always have to construct an INSERT statement -- a pain if they're complicated.I want something as simple as working with a ADO recordset,but in .NET.What can I do to accomplish the following without parameter.add statements?

I'm using the TableAdapter to Insert rows into a database, when I use execute from the Query Builder, the line gets entered into the database, when I enter it via Form button, it doesn't get entered to the database using the same commands.
I have a table adapter for a fairly sizable piece of data. Now with this data I would like to give the user the ability to change the company name and have this reflected in the form on the drop down list of all of the companies once they have clicked submit. However, in order to do so I currently "Fill" the entire table adapter again to achieve this.Is there any way which I could just re-fill the company column from the database in the same tablea dapter.Here is my code for the sub:
Dim NewName As String = txtNewName.Text Dim OldName As String = txtOldName.Text Dim FieldName As String = Me.Text[code]...
I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable" Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
