I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?

I'm presently creating an application which uses Access2007 as the database. No problem there. But Since most use Excel for data-entry, i've created two tables in access linked to excel source file. Any change in excel will reflect in Access database and subsequently in my Application . Until now my application only reads the database and displays records in DataGridView. These records, i then export to excel along with other formatting for direct printing as a report as I have no idea how to make report. Now i want to add data-entry capability to my app using password-protection user-access. So i can directly add new record to source file. Also need to know if There's any way of eliminating Access from the picture entirely....

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 View that i am trying to use to fill a TableAdapter with. In my code i fill the table adapter properly the first time, filter my bindingsource and use datarowviews to loop through the rows of data and perform the updates needed (done by a stored procedure). Now the problem is, after these updates take place, i need to fill the tableadapter again so that it reflects these changes. Sometimes the View i am using will have no results, other times it may.[code]This is the exact Error "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."Okay, you'll notice that i fill my view, then filter those results on the column Number equal to 1. I loop through all those results and update the table my view is created off of. After exiting the loop i hit the second .fill which times out after about 20 seconds. After testing, this time out only seems to occur when MyView does not hold any records.
I use Visual Studio 2010 and sqlserver 2008. All work is done in VB.NET. Also, during debugging, i paused on the second fill, went to Toad for Data Analysts and ran a SELECT * FROM MyView which did not time out and returned the empty result table in about 19 seconds. I have also tried doing a dispose on the tableadapter before the second fill but it has a similar time out. Sorry if this answer seems obvious or something, i'm only an Intern and am still learning the language. That seems to have done the trick, from my understanding that lets it run until it finishes (SQLServer will shut it down if the connection stays open longer than it allows). The ta.fill runs at about the same pace as Toad coming in around 19-20 second mark and does not error after multiple tests.
I have already defined in my SELECT statement in TableAdapter to tell it what to do if the parameters are Null:
SELECT a.ID, a.NameID, b.BNameID
FROM a INNER JOIN b
ON a.ID = b.ID
WHERE ((@NameID IS NULL) OR (a.NameID = @NameID))
AND ((@BNameID IS NULL) OR (b.BNameID = @BNameID))
I have a string qText with the text of a query in it, say qText = "select * from Data". how can I execute it to fill a TableAdapter I have in my form with the resulting data?
View 2 RepliesIn my app (written in VS 2003) I use OleDbDataAdapter's to load data. I have some functions that enable be to change the OleDbDataAdapter.SelectCommand.CommandText at run time, by adding a "WHERE" or "HAVING" section to the SQL command, or updating the "WHERE " or "HAVING" section. This way I have have generic load data functions. (load all invoices for Customer 123, load all invoices for the year 2009, or load all invoices for Customer 123 for the year 2009).

View 4 RepliesI am trying to add NewRow to the database by using datatable in dataset, but before I do that I want to make sure that row is not already there. I create new row for the datatable I am working with, fill it with information. I fill datatable with the row from database that has the same primary key as my NewRow by using tableadapter.fill method, but when I do that my NewRow that was never added to the datatable is filled with information from database(and not information that I assigned to it). I count rows in my datatable before I fill it and it's 0, so why is my NewRow affected by Fill command? (I am using VB.NET 2005 Framework 2.0)

The closest that I've come is getting the password to appear on screen, but it's not masked with asterisks and when I click login it says invalid password. It's almost as if it edits the label right before the text box for the password.

I am a veteran programmer . However , I am new to visual basic 2010 . I am trying to create a database that ould store data within an access file *.mdb .I have created the database which includes multiple tables . moreover i have created app.config file using wizard and my database along with dataset appear in the visual basic 2010 project . moreover when i test the function insert in the dataset the function performs well and the output is correct and i can see the new row added in my access database . however when i try to use the ATLtableadapter.insertquery (ATL is a datatable in my database) function in my form (in view code) the row doesn't get added.
When i first used this function an exception occured was something like first system class exception data.dll something along that lines. . however , when i created a new oledb.oledbconnection and put its connection string as the one in windowsapplication1.my.settings.marketconnectionstring. and used the open comand to open a connection . the message stoppped appearing . however , the insertquery is not adding the row in my database still when i use it in the form.
What's the syntax for an Update query for a table without a primary key?Disclaimer: Frustratingly, adding a primary key is not an option. My program is a small program in a much larger system with poor data management. My development time does not include rewriting the other software.
Note: The database is Microsoft Access.
Note: Similar to: Excel: TableAdapter UpdateCommand for table without primary key
UPDATE: Am I correct in saying, "If the table in the database has no explicit primary key, then there can be no valid TableAdapter UpdateCommand?"
