I'm converting a process from VB 6.0 to VB .Net. The process copies a table from one database table to another database. In many cases they are not linked so a "Select * into Table2 from Table1" is not a solution. Also the source table may be a temporary global table that has a unique structure. The current process reads the source table into an ADODB recordset, obtains the columns attributes to create a new table, creates the new table, builds insert statements from the source table, and then inserts the rows into the new table. I'd like to take advantage of any .Net features that may be more efficient than that. Can anyone point me in the right Direction?
in my project I insert values into a database, each value needs to be unique, currently I am using the following code to check for the value in the database before inserting, if it exists I loop back and generate another value and check again..
Dim SerialCount As Integer SerialCount = 0 Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersMatt-ASUSDocuments im_db.accdb;Persist Security Info=False")

Currently using VB 2008 with MS Access 2003.I have Two Tables with Names - " Company_Data" & "User_Data" in which i have the following columns.....
Company_Data Name|Age|Department|Salary User_Data Name|Age|Department|Updated On
Now, Is there any code that can do the following:when i select a name in the combo box on the form (The list in the combo box is from the Name in the Company_Data table) and click update.It should copy the Details of the Record from Company_Data to User_Data with the current date in "Updated on" column. Note that the columns are not exactly Same. (Salary is not necessary in the User_Data)?
What approach would I take to copy a table from one DB system to a completely different DB system? I can get the source table into a DataTable object, but I don't know how to export it to the target DB. I want the columns to be automatically created with the same names & data type.
I have a DataTable with 20 columns and it have lot of rows. I have created a SQL table which is have the same 20 columns. Now I want to copy the complete Datatable to SQL table using VB.net 2005.
I have a query called qryimportpatients which has fields name, region, DOB and have a table called tblprojectpatients which has the same fields in sql database. On my VB.Net form I have button (Copy Data), which when I click I want to copy all the data from qryimportpatients to tblprojectpatients.

Access databse, On the main form I have a combo box select a table (1 of 50 table names), the subform pulls up the table and users can go to a specific record. Once they move from the subform, how do I capture the subform fields to another table. As the combo table selects from one table, the selected table is different, my primary table is linked by FKey in this "MergedTable" with FKey "TableName" and FKey "item" for each of the 50 tables?

Anyone know how to copy a table from one database to another? I know the statement 'INSERT INTO Table1 SELECT * FROM Table2' but I want to copy from one database to another from a server to a PC. Of course, I could do a select statement for all the records and use a loop to insert them one by one, but surely there is an easier way.
I am working with Vb.Net 2005 and sql server database.
I have a query in sql database (qryImportpatients) - it has 4 fields: prac_no, prac_eid, pat_name, pat_yr. I have a table in sql database (tblProjectpatients) - it has 5 fields: Project_ID, prac_no, prac_eid, pat_name, pat_yr.
Now on my form in VB.Net - I have a textbox (txtProjectID) which has a numeric value. I want to have a function which when called will insert all the datafrom the 4 fields from qryImportpatients to tblProjectpatients and also insert the numeric value (ProjectID) besides each record.
I want to know how can I possibly copy a table with multiple columns and rows into an Array or Collection in VB.NET.I want to know the best solution because I want to use the code for 2 different tables and do some comparisons, and the second table has too many records.I was wondering if in VB.NET there is something similar to Hashmap used in java and a table could look like the following
I'm wanting to allow users to copy some data and be able to pasted it into what ever they want in a nice format - be it Excel, Outlook Notepad, what ever. Those are the main three I would expect my users to use.
I have the code to populate variables with the HTML string and tab separated values.
I'm working on a form that has a few data grid views that are populated from LINQ queries, no problem there it works as it should however that sorting does not work. After doing some reading its because LINQ results do not support sorting.As I have the LINQ results already is there a way of copying the results into a dataset or datatable then binding the data grid view to that so sorting will work?
I have a table that I'm trying to use as a template that I can then copy to a new page. I only got this much
Dim oWord As word.Application Dim oDoc As word.Document Dim oTable As word.Table FileCopy("C:/1535.doc", "C:/1535_1" & ".doc") oWord = New word.Application [Code] .....
So I want to get a copy of oTable then after the page break it makes a new page but I don't know how go to that page and put a copy of oTable.
I'm working with the project that require save all user personal information in one table when they login my system. The problem is too many users login my system per day ( or one user can login/out many time per day), it's very hard to manage. So, I want to add one more function which can specify one user information. My solution is create a text box and a find button to filter the user whose name in text box and copy to other table after that show that table, the problem is I don't know how to do that.
I also try the code which show below, but with that way I can't achieve my require[code]...
Another question is how can I delete all information in a table in database?
What I need to do is if the table has a row then copy the text out of a cell to a radiobutton. The text I have so far is: If EXISTS(ds.Tables("DogBasic").Rows(0).Item("DogName")) Then RBDogName1T.Text = ds.Tables("DogBasic").Rows(0).Item("DogName").ToString Else RBDogName1T.Text = "Add Dog" End If [Code] .....
But I get an error: Error 1 'Exists' is not declared. It may be inaccessible due to its protection level.
I have 2 tables that are related,both have identity columns for primary keys and i am using a vb form to insert data into them,My problem is that i cannot get the child table to get the primary key of the parent table and use this as its foreign key in my database.the data is inserted fine though no foreign key constraint is made.I am wondering if a trigger will do it and if so how. All my inserting of data is done in vb.The user wont insert any keys. all these are identity columns that are auto generated. If a trigger is my way out please illustrate with an example.
what is the best approach in VB.NET to get the entire table from the Ms SQL 2008 R2 database and save it in the program (dynamic?) array or something which is easy to translate into bytes and send to other device via socket communication?
This is a problem with MS Access, but I can't seem to find an MS Access Forum, so I'm asking it here.I have a large table of just one field. The field type is Byte. I use CTRL C and CTRL V to make a copy of the table.I then compare the Source and Destination tables and lo and behold they are different at about record number 8 million.I also tried an Append Query to append to an empty table (I haven't tried a Make Table query).But, similar corruption.The source and destination tables do not end up the same. The Record where the failure occurs varies, but it is always greater than 8 million.I tried this on MS Access 2002 and 2010 (both with an Access 2002 database).
I have a table I created in SQL Server Management Studio. I had to create it there because I needed to use a function for an alpha-numeric ID column that increments itself. I then exported the table, but had to use my local server. Now, in visual studio, I have the local server connection that contains the table I want to copy to a connection for a remote server. I can right-click and select 'Copy', but I can't right-click and 'Paste' into the database I need.
