Client Database From Dialog Box Not Updating Table View Of Data Collected?
Apr 20, 2012
I am currently working on a Database that collects information. Firstly, i use a new windows form to collect that data. I have it set up to where, when the form loads, the database is ready to collect the information fields. And then the form closes on the button click to add that data, it does not update that data table view. It adds it once i close the program and debug it again.
Code: (Open the windows form)
Private Sub btnAddNew_Click_1(sender As System.Object, e As System.EventArgs) Handles btnAddNew.Click
AddNewClientData.ShowDialog()
[Code].....
Problem two: I need to make a button that will increment a cell that was set as an Int, by one, but can't figure out how to put it into code.

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?

Private Sub BooksBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BooksBindingNavigatorSaveItem.Click

I have a program that uses a database for all of its information. The program is just an easier way to understand all of the information.The user uses 1 of 4 search options (FName, LName, MemberID or Startdate). Depending on what they search for depends on which members are displayed in a data grid view.
Upon selecting the desiered member from the data grid view, information about them is then displayed. This information has been split up over 3 tabs called member information, Attendence and payment history.
That all works great. So I now go to the Attendence Tab and wish to update this members attendence by selecting a date from the date time picker, and select the Add attendence button.This also works fine, the attendence is update but the attendence data grid view is not updated automatically.
I have to select the member from the first data grid view to run the code to refresh the members information.So I thought, call the PopulateAttendenceHistory Private sub again and have it update the data grid view... but it still doesnt work.

Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

I'm trying to figure out why my adapter is not updating my SQL database table. I have a form with 3 data grid views on it. If the user changes the display index, width, or visible properties of the columns I want to save their settings. For some reason the adapters update runs without error, but when I check the database table nothing is updated, why? Does it have something to do with the TableMappings?

I have a txt file comprised of a vertical list. The list contains x-amount of groups but what is standard is that they are always made up three entities.Example as follows:
PANNEL A
38
2440
Explained as:
NAME
WIDTH
LENGTH
A list of three items (though list can contain x-amounts) is identical to:
NEW BEAM
38
2440
[code]....
I now need to create a new txt file, which is written as follows:
("NEW BEAM" is "38" x "2440")
("WOOD" is "22" x "610")
("ITEM A" is "50" x "1220")
How van I do this using VB.NET?

Honestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of.
In either case since I guess I can't do that.
Here is some code in a button on a form
Try
ItemsTableAdapter.Update(NewCreationsDataSet1.Items)
LineCodeTableAdapter.Update(NewCreationsDataSet1.LineCode)
Catch ex As Exception

I am an old VB2 programmer and in the process of moving up. In VB2 I could obtain a data row via and index on an access table. I can not find an example on how to do this. I can retrieve a single row using a query, but an index would be faster. I know in Oracle use can use a hirt to direct the query to use the index.Here is what I was during in VB2 (Sample) with no hint.
Set Stock_Tbl = "DataBaseName".openTable(Stock_Tbl_Name)
Stock_Tbl.Index="Symbol_Idx"
Stock.Tbl.Seek="MSFT"
