Saving Updates To Database Using Mysql ?

Mar 11, 2010

I'm using mysql database..I have forms setup main form has datagrid..you can add to this datagrid and save to datbase with my add form and it works fine. I can delete from the datagrid and it works fine...when I select an account to edit is when I have my issue...form edit brings up the selected account but when I save my changes it doesn't save to the selected account it changes my first account in the database......

Here is a sample of my code

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
' 'Save changes to database and exit
Dim intResponse As String
intResponse = MsgBox("Do you want to SAVE Changes to this record?", vbOKCancel, "Save?")
If intResponse = vbOK Then

[CODE]...

MySQL And FTP - MySQL Databases Exists For Saving Values As Strings (text Only)

Sep 22, 2009

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

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.

Saving Info On Mysql?

Jul 18, 2012

I have this form that i need to save on Mysql database but i'm stuck on what I should do.

This form needs to be done every 3 or 4 months. Every saved information stays saved in a row.

This form has alot of radiobuttons,textboxes and comboboxes that I save into mysql database But I also have a datagridview inside that form that needs to be saved as well , So here is where im stuck

I need to keep things simple and efficient. heres two example of what i can do but don't know what to use.

On MYSQL
Example 1:
-User1 Review 1-
Row1(review1) ----info--info---info---info---info----info---
Row2(review2) ----info--info---info---info---info----info---
Row3(review3) ----info--info---info---info---info----info---

DB/Reporting :: DataTable Updates To Database ?

Apr 15, 2008

I have one specific problem, that is relative to DataTable Updates to Database.

Code:

auxDatatable = Mydataset.MyDatatable.GetChanges

Now i'm going to Accept or Reject Changes based on some Criteria. The problem is that I wish to Update Only the Records that in Fact exist on the Database, as you can imagine I was forced to create some Dummy Records in Datatable, to a specific job.

My approach to this issue was to do something like this :

Code:

Private Sub MySub (ByVal auxDatatable As DataTable)

Dim drView As Mydataset.Mydatatable

For i As Integer = 0 To auxDatatable.Rows.Count - 1

[CODE]...

As you can see I tried to Delete the rows that are Dummys, but the rows in fact are not being deleted. As consequence I get an error after that Sub, when i try to make :

Code:

MyTableAdapter.Update(auxDatatable)

This is naturaly caused by the dummy Records.

Sql - Windows Form Not Getting Updates From Database?

Apr 13, 2011

Ive only recently starting fiddling with Visual Basic Express and Sql Databases. Ive managed to get a database up and running, and can query information from it. I have even created a form that can add a new entry to the table im using.The first form has a ComboBox that list the PlayerNames in my table. Form2 allows you to add a new name to the table, but anything I add isnt immediately updated in Form1. I have to relaunch the program to see the new entries. Even then, these new entries dont seem to be permanent as they eventually dissappear.The code I have for Form1:

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

VS 2008 Handle The Updates To The Database?

Oct 1, 2010

what's the best way to handle the updates to the database.For example i have one datagridview that's binded to a datatable (with two fields, id auto incremented and a varchar). The user can do all the operations Insert, Update, Delete.If i insert one row (only the text) and call the update method to save the changes to the database, and after that remove the same row and call the update method the adapter will throw a exception because it didn't update the datatable with the value of the id. So the best way to do this is always calling the fill method after every update?

Allow Database Table Updates From Multiple Programs?

May 17, 2011

Since ADO.Net uses a 'disconnected' model where the data available to a single program is just a copy of what is in the database, what is the normal way to handle multiple programs needing to update the same table in a database? The problem I see is that a program can't update unless his copy of the data is the most up-to-date. Are we supposed to read before updating and hope that the update occurs before someone else changes the data?

Create An Object Of A Class In Which There Are Properties And Functions That Do Database Selects, Updates And Deletes?

Oct 22, 2010

how to implement UI, BL and DAL in a project the way that I see it as a requirement for some projects. The way I am able to do a project now is from a form create an object of a class in which there are properties and functions that do database selects, updates and deletes. Looks to me that doing a project like that is separating the UI from the DAL. In an update button click event I may call Obj. Delete (txtCustID.txt) for example. I don't understand the part of further breaking it down to include a Business layer; in which a vb solution is made up of three solutions.What goes in the BL?Does the BL call the DAL?

Visual Basic 2008 Updates Wrong Record In A MS Access 2007 Database?

Mar 7, 2010

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:
