I have a dataset that is populating a table adapter that I want to be able to save any edits/changes that are done to the dataset back to the database. I know that I'll have to do a loop similar to this one[code]...
View 14 RepliesI have a form with the datagridweiw object. I have connected it to the datasource and it displays the data fine. I also have set the persissions for editing. I am assuming i need a button for accepting changes to table and a button to cancel. My use for the form is to add or delete rows of data and save the changes. The database and application are both in visual basic and sql server express both 2008.

View 1 RepliesI have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all.

My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:

I am trying to loop through a dataset and process n numbers of records at a time.For example lets say I have around 240 records in my dataset. I need to loop through the dataset and then create a new batch of 50 records. so for the dataset which has 240 records I want to create 6 batches. Out of these 6 batches, 5 would have 50 records and and last batch would have 40 records.

What I'd like a user to do is to be able to check that checkbox and when they fire the holidaysavebutton event, that my code will look for any of the checkboxes that are checked and save that line of data to my database. As the code stands now, I am able to get the first line to do this, but none of the lines after will save the data.

I'm creating an admin application that will allow specific users to manage users login credentials for an application. On a form I have a datagrid that is populated by selecting * from Operator table on the DB. I want the admin users to be able to add, edit and delete records from the datagrid and i have enabled these properties on the grid but any changes need to be confirmed by clicking a 'Saves Changes' button. Here's the code behind this button:

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Const cSUBNAME As String = "btnSave_Click"

I have added a new record but when I save these changes I am getting this error: "02/12/2011 11:43:56,frmOperator,btnSave_Click,5,Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information."
I'm using the Visual Basic Express edition 2008 and I'm not able to save the changes to the dataset as well as dataset. While the application is running. I can see the changes are made in the table but the moment I close the application and check the data in the Dataset in the right window or the data in the database in the left window, I see no changesI have also tried the Update property of Table Adapter but no use. I have done Endinit, AcceptChanges everything but moment I clode the application no changes are reflected in dataset or databse.

Inside the program I have a text box in which a user puts in the filepath to a textfile that the program then uses as a series of commands to perform tasks. This works perfectly, however what I would like to to do to make my program faster is associate the file extension .gam with the program, so when a user clicks a .gam file it opens the program and automatically sets said file's location into the text field, as opposed to using the browse button I added and browsing to said file everytime they run the program.
Through this a user could then make a shortcut to said .gam file and run it right from their desktop, as opposed to rummaging around in folders and whatnot. At the moment my method has been thus, I have 2 folders of importance I have archived with the .exe, Gambits Pro.exe, these are: Gambits, and Control, inside of the Gambits folder is the default storage location for .gam files, as when you click the browse button its default directory is that folder. I have also added a few example files in said folder for a user when they download the program.

I have a program that takes data out of an excel worksheet and puts it into VB.NET datasets. The user can then manipulate the data using the windows forms application. At this point, I want the user to have the capability to save his/her data to some kind of file, email that file to a friend, and have the friend be able to view the same data with the windows forms application. I'm not looking for syntax, just a suggestion of a good way to go about this. Would the best way be to write to an access database and then use sql queries to get it out again? I've had a hard time figuring out how to write a dataset to access via VB.NET.
1. Start with Excel Data
2. Convert to VB.NET Datasets
3. Manipulate Data in form applicaiton
4. Save manipulated data in some type of file that can be sent to a friend
5. Friend opens manipulated data file in form application and can view and manipulate the data further

In my project,I used the wizard in VB.NET2008 Express to connect to my database. I have a data connector, adapter, and dataset controls on my form. I have been able to load the information into the dataset, and used the datCustomers.Customers.AddCustomersRow to add a new row to the dataset with information.
I now want to save the updated dataset to the database. I have tried using the adapterCustomers.Update(datCustomers) command to no avail. how to save the dataset to the database?
When I put information into my database form, the data is not permanently saved to my database?

View 6 RepliesI'm afraid this is a very simple question, but I can't figure it out... I hardly ever use the DataGridView (usually use a third party grid) so I never needed to do this before.Anyway, I have a DataGridView that is data-bound to a List(Of SomeClass). The grid is not ReadOnly, but I made every column ReadOnly except the very first, which is a boolean column so it displays a checkbox. This way, the user cannot edit any cell value, but he can check/uncheck the checkbox in the first column.
What I need now basically is an event that is raised when the user (not programmatically) changes the value of this checkbox. I also need to be able to retrieve the bound item from that event (from the row number I think?) but that should be no problem, I hope.Anyway, there's a bunch of events that looked promising but all have something I don't want:
1. CellBeginEdit - Fires before the checkbox value has changed, so can't use this.
2. CellEndEdit - Only fires after the edited row loses focus. I want to save it back to the database as soon as the user changes the checkbox value!
3. CellValueChanged - Same problem as nr 2.
I'm sure it must be possible for me to react as soon as the user changes the value of the checkbox? How can I do this?
Part of my MVC 3 VB.NET has a view that uses a list(of model) and a for each on that model to list all the contents.. The problem is that a selectlist is part of each item.. When the value is selected for each item it is not being posted back to the controller with the rest of the items.[code]....
