Saving Directly From A Datagrid To A Table In A Database?

Apr 7, 2011

Basically I have a DataGrid on a form that is used to monitor attendance. I do this by making the data types for the relevant fields boolean so that at runtime, they appear as check boxes that the user can tick. If the user ticks this then the table in MySQL saves this as a 1, or if it is left unticked the table saves it as a 0. I then use those values in a mathematical equation to calculate weekly attendance.

My problem, however, is with saving changes to the table itself. Initially I set a primary key which was fine and allowed me to save. However I needed to turn that primary key to a foreign key and when I do that, I am told that I need a primary key. Now I got round that before when I was entering data into a text box and in my SQL query I'd simply put as my value being " & (name of textbox).Text & " but when I am entering data straight onto the datagrid, I am unsure of what to put in my SQL statement.

StudentID (Was primary key but turned it into foreign key)
Name
Surname
Monday

[cod]....

My friend from college told me it's probably because there are multiple records in the database and can't distinguish between the two (as perhaps there's no WHERE clause in that UpdateCommand) but I doubt it as it was working perfectly well with multiple records when StudentID was a primary key.

Using Command Buttons To Add Data To On Screen Table / Then Saving To Database

Apr 20, 2011

i am creating a system where when a command button is pressed, it adds the data corresponding to that command button to a Table of the screen. And basically im at my wits end at how to do this, i have tried using SQL and databases but all i seem to be able to do is type data into the table and this is not what i want.Basically the table has 3 columns at the moment, which are filled in column at a time, and this need to be done by pressing command buttons. To explain this basically there are 8 buttons, which can be pressed to enter into the first column, once one of these buttons is pressed and second set of buttons appear which correspond to the second column and after one of these buttons is pressed the 3rd set of buttons appears to enter into the third column.Once the last button is pressed that is the first row filled in and the user can again press a button from the first set. Its basically a system for rapidly entering data into this table through the corresponding buttons.I have the buttons appearing and all that working fine, but thats basically just the layout. I need to know how to enter the data into the table.i have to use a SQL database, i only added that as at the end of the session, the entire table of data needs to be added to a master database but i can attempt this at a later date.

Mvc - Saving Files And Names To Database Table Using For Each On Request.files

Mar 9, 2012

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]

Jan 22, 2011

VS 2008 Saving Changes From DataViewGrid To Table?

Nov 10, 2009

I added a DVG to the form. Then I clicked on the small box and selected a data source through the design screen. I chose the connection and then the sproc to get the data. This all works fine. That was added in the Load sub automatically. I will make changes to the cells by code rather than allowing the user to change the cells themselves. Then I want to click a button and save the changes to the table. Everything I have tried does not work.

Adding Then Saving A Row Into A Table Using Insert Through A Tableadaptor

Feb 3, 2010

I have 3 tables. Customer,item, and price, where price holds the customerid,itemid, and the price. This lets me set a different price for each item based on who is buying it. I am trying to add data to the price table from a form which gets a customerid and itemid, and the price they will be charged. The only table to be updated is the price table.

Private Sub SaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveaspButton.Click
' cust and item are pulled in when the user inputs a name, the lookuptable is used to put into an unseen label

This does add a table in the table visual studios uses but wont save it to the main database. This means I can do a fill method and see the row while the program is running, but wont be there next time I run the program.

VS 2010 - Saving Date To Access Table

Jul 3, 2011

I'm using a MaskedTextBox, named txtDOB, into which the user types a date (the mask property is "00/00/0000"). This value is then stored in an array
Dim NewStudentFields(37) As Object
NewStudentFields(4) = txtDOB.Text
And the array is passed to a subroutine which uses the data to put into a new table row.

Some of the code from this sub:
da.InsertCommand = New OleDbCommand("INSERT INTO tblStudentInfo (FullName, FirstName, LastName, Gender, DateOfBirth, etc.etc.) VALUES (@FullName, @FirstName, @LastName, @Gender, @DateOfBirth)")
da.InsertCommand.Parameters.Add("@DateOfBirth", OleDbType.DBDate, "DateOfBirth")
If NewStudentFields(4) <> " / /" Then
dsNewRow.Item("DateOfBirth") = DateTime.Parse(NewStudentFields(4))
Else
IsDBNull(dsNewRow.Item("DateOfBirth") = True)
End If

The code executes as far as the red line which triggers the error message "Conversion from string "DateOfBirth" to type 'Integer' is not valid." There's probably something wrong with the final "If...End if", too!

Saving Updates To Data Table Using Binding Navigator Save Item Button?

Jun 7, 2012

I am trying to understand how the binding navigator buttons are actually working.

I started by creating a table called "Students" in MS Access,

I then "dragged and dropped" that table onto my VB form after importing the data connection.

When I debug, I click the add new (the yellow plus "+") then I type info into my fields (700_Number, First_Name, MI, Last_Name). (700_Number=Primary Key)

After I am finished typing into the four text boxes, I click save. If I end my program then start the debugger again, the record is still there...it goes away only if I change some of the code anywhere in my program.

Also, I am trying to use the record I just put into my database for another part of my program. I use this line of code:

MsgBox(frmAddStudent.DrByrdsTaskListAppDBDataSet.Tables("Students").Rows(0))

This is just to see if what I am trying to put into my database is actually making it there. Every time I run, this message box turns up blank.

Transferring Data From One Field In A Table In A Database To Another Field In A Different Table But Same Database In .NET?

Jul 22, 2010

I am creating a database in VB.NET for a movie rental place. I currently have three forms;

Member Information
DVD Information
Borrow DVDs

What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;

INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]

but that has been coming up with error codes and completely not working.

Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?

DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?

Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?

The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

.net - Saving To SQL Database?

Feb 29, 2012

I have managed to create a connection to the database and am able to save information to it from my form, the form contains 22 textboxes, a save and another exit button. I have set the form to retrieve data in the form_load. I have used the "UPDATE" SQL command on the save button and it does save the data on all 22 textboxes (all textboxes are linked to their separate columns). But only one record will be needed that is why I did not use the "INSERT" command.

The problem arises when I click the save button, all (19) textboxes are saved but when I retrieve the text (by reloading the form), each of the 20, 21, 22 textboxes (only) the text of the 20th textbox keeps on moving tho the next textbox e.g. 20>21>22>20>21>22 is interchanged amongst themselves.

60K Data Saving To Database

Nov 6, 2011

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.
