Tried searching and found some related issues but none exactly like I was having
I iterate thorugh a DGV and write to one of the fields of the row. After it writes this field, I do an update() command.
I have written an application to perform a simple CRUD operation i've used MVC design pattern... DAL was designed using the wizard. I was able preserve the olds value of teh fields of EMployee class using a seperatemethod
PreserveOldValues(){ //code}
in the SearchByIndex() i call the fill method and i used the data to initialize the current Employee object also i preserve those values using PreserveOldValues() the i call update() and internall i pass the preserved values......However it doesnt do concurrencies and updates..
I've got a question below:load data from a table in database into a datagridview,make change in datagridview,and use update function to update change back to tablebut 13 changes, only 12 being update back to databaseonly the top row on the datagridview not being update??
For Each orow As DataGridViewRow In DataGridView1.Rows
orow.Cells(1).Value = TextBox1.Text

1. When the program is running and if i save the data , it gets saved in the db. But when i close the program and again run it the data gets discarded
2. Say first i have saved the info about person 'A', and then When i Save then info of Person 'B', instead of the the details of B the details of A is getting duplicated[code]...
1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."
On programming assignment without having any real experience in vb. I guess I don't understand subroutines that well. When the program runs it never goes to the computer's turn and does not update the users score either. This assignment is already in but would like to know what is going wrong. Using VB 2010, and this is windows application.
Code:
Public Class Form1
Dim Myturn As Integer
Dim Computerturn As Integer
[CODE]...
I have a main form with datagridview containing a list of contacts:
VB
Public Class Form1
Private Db As New DataClasses1DataContext
Private Sub Form1_Load
[Code]....
After saving, I get the correct message ("Saved"), and the DataGridView in the first form gets updated in real time.
But... when I take look at the data (or close and reopen the forms) the data in the database (SQL server) have not changed! What happens!
I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.
[Code]...
This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I am having a problem with visual studios 2010. I am creating ASP.net pages, but when I test/debug my code, the code-behind files runs the same code that was run the first time it was debuged this session. Meaning, to test new code-lines, I have to restart Visual Studio altogether?
View 1 RepliesI have a VB project that I created a simple setup project to deploy. It installs fine except for one problem. It crashes because it can't read its own application directory. Included with the program are an xml and schema file that it needs to read when starting.dditionally it may create a log file, also in its application directory. Either of these will return errors under the default install. This was not an issue when running the program in VS and if modify the program to work with another directly like C:Temp. I have a workaround in which I change the permissions of Users group to Full Control for the application directory

Alright, when I open my program I want it to check for updates and if there is an update I want it to download. So far I have a text file saying the most recent version and then it downloads that file and compares it to the current file version. If the current file version < recent version then it will download the file. :O Can someone help me with the code? :3 I have a hosting server with direct download links.
View 5 Replieson my program i have an activation in it and in order to activate the program you need to enter a code that is stored in the settings. so i was looking through my computer and i found the programs config file. and so I opened it and i found all of the codes for the activation.

View 3 RepliesI have antyped dataset and simlpy want to update a record by using dataadapter but the aupdate method affect only ONE Item
Here is the code :
Dim cb3 As New OleDb.OleDbCommandBuilder(da3)
DSBANQUE.Tables("BANQUES").Rows(INC2).Item(0) = BANQREB.Text
[CODE]...
It updates only item no(0) and give me the massage of the RECORD UPDATED but it dosnt it returns the same value for the other items (1,2,3,4,5)
Before performing an update, the application must search for that record in the database. Once it's found then it return to the Data access layer. Typicaly when i return rows i return them in a dataset. The i send it to the client to load on to the ListView Constrol or to textbooxes. therefore data was sent from the dataset object, therefore onces the user has made updates to the data, first i must update the dataset.
In the Data access layer i can write method that contains the command object for update DB and bind it with the current Dataset so that each time dataset updates it sychrinizes DB with it. Assume i have a method called update() in teh business layer that calls the updateDB in the DataAccess Layer, how can i call the Update() of the business layer each time the user updates the dataset?

View 3 RepliesI'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated.Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion:
public void Update(int cusID)
{
SqlCommand objSqlCommand = new SqlCommand();
Customer cust = new Customer();
[code]....
The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated!
I am using VB.Net 2008 and ADO.Net to do a Batch Update to our Oracle database. The updates are working, but there is a trigger on the table before the row is updated to enforce a member's termination termination date. So if I was trying to set the termination date (via the batch update) to 31-Jan-2010 but the member had a claim that was processed on 2-Feb-2010 the trigger would force the termination date to be 2-Feb-2010. However, the trigger is NOT executing when the batch update runs?Is there any Oracle DB Admin option that would disable Triggers on Batch Update?

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?
