Using Command Buttons To Add Data To On Screen Table / Then Saving To Database
Apr 20, 2011i 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.

Saving Updates To Data Table Using Binding Navigator Save Item Button?
Jun 7, 2012I 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.

VS 2008 Saving Changes From DataViewGrid To Table?
Nov 10, 2009I 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.

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.
PictureBox - How To Resize Image Before Saving To SQL Table
Apr 27, 2011I have some problem about image sizing, citing the process: I've create 2 button and picture box. The button1 load opendialog to load image then the image will be viewed at picturebox and the button2 will save to sql table. My problem is how could I resize the image before saving to sql table.
My code:
Button1_click
Picturebox1.image=image.fromfile(opendialog.filename)
end
Button2_click
--before saving
dim myImage as Image=Picturebox.image
How could I resize the actual dimension of image?
Saving Directly From A Datagrid To A Table In A Database?
Apr 7, 2011Basically 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.

View 2 RepliesVS 2010 - Saving Date To Access Table
Jul 3, 2011I'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!

View 2 RepliesSaving Replicated Data - Current Data Saved To Appear In Page Within All The Relevant Fields?
Jun 2, 2010What 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.
