Data In Application Not Saving
Aug 19, 2011
I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table
[code...]
I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.
I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.
I have provided the code below. Please take a look and give me some direction.

I'm a newbee with VBnet , I use vbnet2005 I have a major form called FORM1, and when I click the bottons in it it shows another form for example-I have these some forms (printscreen):
FORM1 - major form
FORM2 - calculation form ( there are few forms like this)
FORM3 - result form
What I need is:When I open FORM2 and get results I push the botton SEND and then it should send the values into FORM3 I don't know if the public variable will be good here because they are not constant , I can get different results in FORM2 ,and these results should be writen in textboxes only after I push send bottom.
I hope it is clear , I don't know how to do it,if you can give me a code for this or detailed answer , I would be very glad.

rewriting a class I use for saving Treeview data to a XML file for use of saving ListView data I can't really figure out the rewrite, I'm stucked, unfortunately Listviews seems to be a big problem for me in general.
Option Strict On
''' <summary>
''' The TreeViewDataAccess class allows the nodes within a TreeView to be
''' persisted to xml for later retrevial.

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I have made an application and I have many listviews, dockable menu bars etc and I want the user to be able to save the layout of the design of the application once they make changes to it.
For example on my listview I have 3 column, "column 1", "column 2" and "column 3" and they might want to place "column 3" between 1 and 2 as they might prefer this view instead.
How can I code it so that "column 3" wont go back to the default location when they load up the application again after they exit it?

I'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?
- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.
- I can afford delay in the sql database, meant the data might not be necessary close to real time.

I have a very simple DataSet linked to a ListBox. I need the User to be able to add Data and have used the following code (in a ToolStrip command button):
Dim newFileRow As DataRow = Database1DataSet.Tables("tbl_Files").NewRow()
newFileRow("File Name") = fleName
newFileRow("File Path") = flePath
[Code]....
This seems to work ok - the new Data immediately appears in the ListBox. However, as soon as I close the form all of the Data in the DataSet is lost.

I have created a form, that calculates Hotels billing, with one box I can input Number of nights a customer stayed which is £32.50 a night per room and the other box £4.50 for breakfast, there is a deposit of £25.00 which gets deducted upon departure. I have created this form with success along with a clear button But here is the tricky part- I want to create a total button which will display a summary information about the bills paid on that day regardless of how long they have stayed and how many breakfasts consumed. this should include, the total number of bills paid, the total number of nights paid for, the number of breakfasts paid for, the total amount of all the bills added together including the deposit.

What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

I made a query for inserting a value from text box to MS ACCESS db
sql = "INSERT INTO Equipment (port_number,display_name,equipment,tonnage,user_privilage) VALUES (" & CLng(txtPort.Text) & ", '" & CStr(txtDisplay.Text) & "', '" & CStr(txtCA.Text) & "', " & CLng(txtTonnage.Text) & ", '" & CStr(cmbUser.Text) & "')"
Actually I meant for inserting the data entered in the text box, but now saving is the code itself i,e; in port_number column 'CIng(txtPort.Text) ' will be saved
