View 4 Replies2005 with ms access 2003 batch update
View 18 RepliesI want to know is there any functions or methods that i can use to batch update the data to MS access from vb.net 2005?Here is my case:I have around 70 records to update back to MS Access.Currently I only know update row by row. So, it means i need to loop through all rows. (I also have where ...=... and ...=... and ...=... in update command.)Its not a good idea because if some where went wrong during updating.The previous updated data will be in DB but the rest will not. So, data will not correct and up-to-date.So, I want to use Batch processing. If something go wrong, all will not update. If updating is OK, then all will be in DB.

Is there any method to do batch update winForm in VB 2010
Using Microsoft Access2007 as database, VB 2010 WinForm (DataGridview + Textbox)
There are a lot of record need to be Updated, It is very efficient if that data is just going through Batch Update, meaning just one click will update all the data rather than click one by one.
Any Demo or code showing how to do this Batch Update (VB.net).
I am trying to update a table across "non" linked SQL servers using:C# or VB.net and ADO.net sqlDataAdapter.
I need to use DataTables and sqlDataAdapter.Very Important I need to use BatchUpdate and avoid looping through the DataTable
The table designs in Server 1 differ from table design in Server 2.

Server 1. Table 1

I am using VB.Net 2008 and ADO.Net to do a Batch Update to our Oracle database. The updates are working, but there is a trigger on the table before the row is updated to enforce a member's termination termination date. So if I was trying to set the termination date (via the batch update) to 31-Jan-2010 but the member had a claim that was processed on 2-Feb-2010 the trigger would force the termination date to be 2-Feb-2010. However, the trigger is NOT executing when the batch update runs?Is there any Oracle DB Admin option that would disable Triggers on Batch Update?
View 2 RepliesI would like to run a .exe file made with visual studio 2003 but I get an error every time I run it on a windows 7 machine, vista machine, and xp machine. The error on Windows 7 and vista says "application has stopped working" and then makes me close the error box. In windows xp it's a little different error, "the application failed to operate (0xc0000135) Click on OK to terminate the application."
View 3 RepliesI support applications in VB6 and VB2003, and I'm trying to upgrade the VB6 app to VB2005, so I have three versions of Visual Studio on my pc. I ran VS2005 and opened the VB6 app to launch the upgrade wizard. It seemed to run fine until it threw an error saying it could not find the project it just created. The project I'm trying to upgrade is called MGxFromSAP.vbp. The error said it could not find MGxFromSAP.vbproj. The project file it actually created is called MGxFromSAP.vbproj.vs7.vbproj. When I try to open this project in VS2005 it says it was created in an earlier version of Visual Studio and needs to be upgraded.Did it perhaps invoke the VB2003 upgrade wizard instead of the new one? How would I be able to tell?
Should I just let VS2005 upgrade the vs7 project or should I try to deinstall the old VS2003 upgrade wizard and rerun the upgrade from scratch?
I have the code below, that is throwing errors when I try to print [code]Can anybody see what could be wrong with my code? if I were to take out the loop i.e. printing more than one file it prints fine????

View 7 RepliesEnvironment = 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?

As you may have seen in my other post, I have to switch over an all text SQL statement based database interaction program to using parameterized queries instead.I remember doing it this way in college but I don't seem to be able to recall one part of it. The program I wrote back then and some code samples here both point to doing the code as I did so far:
m_strSQL = "UPDATE [OWNER DATA] SET [FIRST NAME] = @strFName"
m_strSQL &= ",[LAST NAME] = @strLName"
Dim upCMD As New OleDb.OleDbCommand(m_strSQL, m_Connection)
upCMD.Parameters.Add("@strFName", OleDb.OleDbType.Char, 30, "[First Name]")
[Code]...
it ran the SQL statement and that's that. Can I just do that with a parameterized query too without using the adapter.update()? And for bonus points, why the heck did I use that command in my old college program cuz I sure don't know?

I have recently wanted to start work on an application that uses an MS-ACCESS database. The problem is that no matter what I do, the actual database will not retain any records added. I have followed the Microsoft examples to the letter and it does not work. As long as I have my app running I can add, edit and delete the records. As soon as I close it and run it again, all the records are gone. The mdb is not read only, I've checked it. I also decided to try the my video collection example program that is included with VB 2005 and it will not retain any records either. Is there any code I need to add to get this to work or is my copy of VB 2005 broken? This is extremely frustration because I plunked down a lot of money for Visual Studio 2005 Professional. This is a key feature and it should work. Microsoft had me do a reinstall and apply a couple of patches and it still did the same thing. They told me either I am not coding it right or my system is flaking out. I did a fresh install of Windows (I even formatted the drive before installing), and reinstalled VS yet again and even with that being the only program on there, it still will not work. So I installed all my programs again, restored my backups and now a day and a half later I am writing this.
View 9 RepliesI'm trying to use a BackgroundWorker process to update the status on servers once a Refresh button is hit.add all ListViewItems to an ArrayList and pass that ArrayList to the worker process to update. Once it was done updating, I would clear all items from the ListView, and then refresh the ListView with the new ArrayList with the updated ListViewItems.When I get to this line of code in the RefreshListView function:
'POS_IP_ADDRESS is just a constant I created with the column index in the event I decide to change the layout of the list view columns at a later time
objItem.SubItems(POS_IP_ADDRESS).Text = strIPAddr
I get a InvalidOperationException stating Cross-thread operation not valid: Control lstStatus (my list view object) access from thread other than the thread it was created on.Do the ListViewItem objects have a tie back to the original ListView items when I pass the ListViewItems to the ArrayList? I just want to edit the objects in a buffer and refresh the ListView... does this make sense to do? Why can I not update the item in an ArrayList?
