Database Book Sample Code Not Saving Changes To It

Apr 28, 2011

I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".

I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.

It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.

I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...

Datagridview :: Saving Changes Not Working Properly?

Jan 25, 2010

i have a windows forms app which displays a bunch of records from my sql database. when i modify records in the grid and click on save, all changes are saved EXCEPT the changes made to the currently highlighted row. they aren't written out the database until i exit the actual program, despite clicking on my save button.so for example, if i change 5 different records in the grid, and click on save, and then click on refresh to reload the data from the database, 4 out of the 5 are saved correctly, but the row that is currently highlighted (meaning, the last row i changed) still has the old data.My code for the save button look like:

Code:
Private Sub TerritoryBindingNavigatorSaveItem_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TerritoryBindingNavigatorSaveItem.Click

DB/Reporting :: INSERT INTO Statement Working But Not Saving?

May 19, 2012

I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.

vb.net code below

Code:
Try
Dim cmd As New SqlCommand
cmd.Connection = con

Saving Code To Reference Multiple Times?

Jan 10, 2011

I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something

.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.
