Access Create Multiple Records Based On A Date Range?
Oct 19, 2011I have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...

Way To Get Unique Records From Datatable?
Aug 13, 2011I have a DataTable with multiple columns including AccountNumber, Year, and Month. I am exporting the information in this table to an Excel workbook. Since this table has the potential to be extremely large, I must check the number of records in the table (since Excel can only have 65536 rows or something like that. If the original table is small enough, I need to put all of the records in a single worksheet. If there are too many records for one worksheet, I need to separate the records into multiple worksheets based on AccountNumber. Additionally, if there are too many records for a specific AccountNumber then I need to split that AccountNumber into multiple worksheets based on Year.ng:
Worksheet Name ---- Number of Records
1111 ---- 150,000
2222 ---- 50,000

2005 - Unable To Get Distinct Records From Datatable Using DefaultView.ToTable?
Mar 14, 2012I am building a custom search control in VB.NET and came across a problem getting distinct records into my datagridview. I want to bring exact matches back first so I run 2 of the same query on the same table with a slight difference:
select ... like "code%"
select ... like "%code%"
I have a datatable that I need to get distinct records from; I am append records from a sql query to the end of the datatable so I cannot use a union in sql to return the dataset (I want to preserve the order which the rows are added) I have been using this which is working fine for 2 fields:
dt2 = dt.DefaultView.ToTable(True, "Code", "Name")
But when I have 3 (or more) fields I get duplicates ONLY for the row I am querying:
dt2 = dt.DefaultView.ToTable(True, "Code", "Name", "Initial")
select ... like "initial%"
select ... like "%intial%"
I am clearing the datagridview.source before rebuilding this. Is there a way to get the distinct rows this way or should I just build something myself to remove the duplicates from the second datatable before appending them to the new table?

Add Multiple Records To A Datagridview?
Aug 25, 2009I have two problems with my datagridview in VB 2005 that I did not encounter in VB6. I would like to add multiple records to a datagridview by allowing the user to tab and type.When they get to the end of a record and tab it should go to the next record like Access does. The user can move to the next record and it even shows the pencil on the left leading them to believe that a new record is being created. But, it will not create the record unless they first click on my button that will add the record with the code BindingSource2.AddNew(). I use a bindingsource to populate the datagridview. Here are some snipits of my code for clarity:
DataGrid2.DataSource = BindingSource2
GetDataDetail(
"Select * from [Order Detail] Where [Order Detail ID] = Null")

Can't Select Multiple Records In SQL With ASP.net?
Nov 18, 2011I have problem and I've been looking for a week now on how to solve it. Yesterday I thought I solved but apparently I didn't when I tried the query with new data added in my database.Here's my query
Public Function getTicketsByBeginstation(ByVal station As String) As Array
Dim r As Array
r = (From u In treinDataContext.Tickets Where u.ritId =[code].....
The problem I have is: when I have a station selected there are more than 1 trajecten (connections in English) but I had to use the .first else Visual Studio would give the error "the '=' operator is not defined for 'integers' and 'system.linq. IQueryable(of integer)".
So I give the name of a station -> I have to select all trajectens with the given station as beginstation -> I have to select all ritten which have the given trajecten -> I have to select all tickets which have the given ritten So: I have to show all tickets for a certain station.

Multiple Records On A Form?
Oct 25, 2010I have a form that is going to displays the same field from each of my 185 records. How do I get it to show all records for that field without using a data grid. If you think of this form as a layout of a parking lot and each field is a parking spot then what I am trying to do is display the assigned parking spots. When you click on the spot I want to open a second form that I already created to display and edit that spot.

Append Multiple Records On Transform
Feb 23, 2011Using the FileHelpers library to do some great things in VB.NET. Parsing files with dynamic classes built from text file templates. One thing I can't find: A way to read in a single record and determine that it should result in the generation of two records.[code]Ideally in this next line I would like it to see certain conditions and be able to generate two records from a single source line. Dim PayRecords() As Object = engine. Transform Records(FromRecords)Alternately, if there is a way to implement the "ITransformable(Of ..." TransformTo() and have it return multiple records, I could put the logic in the dynamic class definition TransformTo() method.[code]
View 1 RepliesInserting Multiple Identical Records Into Sql?
Jan 24, 2012I wish to insert a row into an SQL table a multiple number of times. The only field that will change is the Primary key ID which will update automatically.
To enter the INSERT into a loop seems very inefficient (time). The only other way I can find to do this is build up an array of values and do a multiple INSERT but again this seems very inefficient (memory) when the values will all be identical.
Is there a way of saying insert this row a variable number of times?

Print Multiple Page From Database Records?
Jul 27, 2009I'm using Visual Studio 2005, and MSSQL.I need to print records from database on the preview document according to my select statement condition. I have no problem printing one page, but when the records exceed one page it does not go to the next page. I've tried setting e.morepages to true, but it just prints infinite number of pages with the same result. I'm guessing the problem is with my pointer, where the if-else condition is always true so it just keeps printing.

Update Database Records Using Multiple Threads
May 27, 2012Been a while since I did any VB work, and have started a new project that is a Windows Service that will update a database using multiple threads. I am testing this out with a dataset that consists of a "device name" and a "device IP", pinging the device, and attempting to update the device's "status".
I have it working in a single-thread type configuration, but would like to be able to ping and update different records across multiple threads (for obvious reasons).
The problem I'm having is with the logic mainly. When the service is started, I get all the devices from the database and fill a DataSet. From there, I am looping through the dataset's rows, pinging each device and updating the record. I know how to spawn multiple threads, but I do not know how to keep track of updating the correct record and also making sure that all records are checked in some kind of order. Like, if user specifies 5 threads, I need it to get record 1, thread finishes, gets record 6 (while other threads execute), or something like that.
Note: this does no interface updating or anything like that. Only updates a database record's field value.
VS 2010 - Combining Multiple Records And Doing Calculations

- Should add up totals (Amount paid, Amount not paid, Amount Overdue, Total Amount)
- Should be withing specific date range.
Everything in this table has been saved as varchar except invoice id and unique.
