View 3 RepliesWe are filling a combobox with information of a table. (we read a field for filling the combobox and the id)
It's necessary that if we choose an item in the combobox we also get the id of the table.How do we put the id into the combobox so can read this id after selecting an item.
I have a form and it is databound to a Access table with the standard TABLEADAPTER wizard. All works well HOWEVER, new records are not displayed in sorted order.When I add a new RECORD, it can go anywhere within the table. When I move around the table using the TABLEADAPTER Manager, the newly added record does not appear in sorted order.Furthermore, when I restart the application and show the form (which issued a FILL command), the records are not sorted.The SELECT I am using is fairly simple:
SELECT [list of fields] FROM TableXYZ ORDER By [sort field]
This HOWEVER, does not appear to work.get the table to be sorted when filled?Other information - the table in question has the field that is specified in the ORDER BY clause which is the same as the Primary Key.As an example, in the table there are records with the following KEY:
4313, 4314, 4315
When I insert a new record, it might fall between 4313 and 4314. Lets assume I add 9999. I expect it to be at the end of the list however, it appears between 4313 and 4314.FYI Also tried this in the code as well:
TableBindingSouce.Sort = "field1 ASC"
How can I control what is filled into the table adapter at runtime? Basically, I have a table full of thousands of rows, and I want to limit this to just 1 row. I want to specify an ID number and be able to pull up that row in the table, and I need to do this at run time. What are my options, and what is the easiest way? I want to make sure the data is still linked to the original row in my database, that way the changes are saved properly.
View 5 RepliesI made a web application were you can check if somebody paid for their e-ticket and if so once you push the send mail button the person will receive his/her E-ticket with all the information regarding the activities they ordered.
I just have one problem the mail that I send collects data from a data grid and puts that in a static array.
Dim testarray(20, 1) As String
And of course the code to get the data from the data grid into the array
A part of the html code to send the e-mail is as following
"<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(0, 1) & "</span>" & "Activity: " & "<span style=""font-size:14pt;"">" & testarray(0, 0) & "</span>" & "." & "<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(1, 1) & "</span>" etc.
The Testarray(0, 1) and up are filled with the corresponding amount of tickets and for which activity. As you can understand if for example Testarray(1, 0) and Testarray (1, 1) do not exists because there is no corresponding ticket amount and activity in the grid. But Testarray(0, 0) and Testarray(0, 1) do exists, the person will still receive a empty line in his/her mail
Tickets: 5 : Activity: Sleeping
Tickets: Activity:
I know that with a dynamic array maybe I could fix that problem, I was wondering if there is a work around so I can check if a Testarray is empty or not and then only when its filled with data it will write the line into the e-mail.

I want to copy Header Data from one table to another. I know how to do this if the table data is exactly the same, but I need to generate a new HeaderKey for the destination table.Example - I am copying SalesOrder Header Data into the PickList Header Table, but I need to also add a PickListHeaderKey when I do so. It cannot be the SalesOrderHeaderKey which will be copied also.

DestinationTable (PickListHeaderTable)

How can I edit this command to include the PickListHeaderKey, which needs to be inserted at the same time or before the rest of the data is copied?

I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?
