.net - TableAdapter Update Fail?
Sep 9, 2010
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?

I am having an issue with the SQLCommand query update handling apostrophes. I have a gridview that accepts edited text which might have apostrophes and other such accent characters.The UPDATE keeps throwing errors on the apostrophes in the text entered causing the SQL UPDATE to fail.
Here is the code:
Dim lbl1 As Label = GridView3.Rows(e.RowIndex).Cells(0).FindControl("Label1")
IDVal = lbl1.Text

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:
Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scratchpad3)
and the table that I need to update is called ExceptionsEdit.

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
customer_code_PK customer_name
SHELLShell Oil
BPBritish Petrolium
MOBMobile
In very simplified terms, code does the following;
sub on form load
fill dataset with database records (select * from customers)
[code]....
The datagridview loads the records correctly.Here is the sequence of operations that produces the bizzar behaviour.In the editable datagrid;
1.remove the row with PK = MOB -> save_button -> Database correctly updates
2.add a new row with PK = KFC -> save_button -> Database correctly updates
3.remove row with PK = SHELL -> save_button -> Database exception occurs
On this last command, the row SHELL is INSERTED!!, not removed.However, If I change ths save_button routine to this
save_button
call generate_custom_updateinsertdeletecommands
bindingsource endedit
[code]....
It works correctly !Is it correct that you would need to "refresh" the sql update commands after every tableadapter.update?

I am writing some data to my Database using TableAdpater.Update and the operation can take up to one minute to complete.
Is there some way to report the progress of this to the user because they think it has stopped responding.

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 am trying to use VB.net to update a datarow (record) using a tableadapter but it won't update.
I created a tableadapter based on the following query which will add a new row, but can't find the way to update the row already in the database.
SELECT Player_ID, FirstName, LastName, Gender, Notes
FROM tblPlayerInfo
WHERE (Player_ID = @Selected_Player_ID)

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).

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.
Like this:
FundResultContainer.xsd - FundResultContainer.vb -- FundResultContainer.designer.vb - FundResultContainer.xsc - FundResultContainer.xss - FundResultContainer1.Designer.vb
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 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!

I am currently trying to write a little wrapper around post-review to automatically post however this function fails when it comes to Dim results As String = sOut.ReadToEnd() and I can;t suss out why,
Edit: It doesn't produce an error it just seems to go into ReadToEnd() never to return
Function postReview() As String
Dim psi As ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd.exe")
psi.UseShellExecute = False
[code]....
Further Info: The actual command is working as I can see it posting to Review Board. But it just seems to get stuck in a loop while waiting on the Stream to complete. I have tried with Read and Readline with no luck?

Unfortunately, the line ddlBuildAddr.SelectedIndex = addressId is failing. Looking at this line through the debugger, the SelectedIndex goes to -1, while addressId goes to 2. What gives? Why would the assignment operator flatout not work?

My understanding of assert.fail was that if the line is executed, the test will fail.owever, I have found an instance where the assert.fail is executed, but the test passes.If the Assert.Fail statement is within a try block, the test will ALWAYS pass, even if the code execution executes the assert.fail. For example, the following test will always pass, even if the sub fails to throw an exception.
