I have 200 cars in my database. I may want to select many ie all Ford's and update their color to Blue, I may want to select the top 20 and update them to have a milage of < 20,000..How can I do this on a form? Many otherwise databases I update have an ID in a textbox and I have a SQL command that updates WHERE ID = @ID..I guess some kind of loop? but where do I get the id's? load all the cars into a listview? datagrid..
View 5 RepliesI have added a datarepeater to my project. I have added several items from datasource.
Some of the items need to be updated constantly. I tried to put my filler of the datarepeater to a timer, but it caused several problems.
Is it possible that I could put only the labels that need to be updated, to the timer. If so, how to give reference that which datarepeater row this lable belong to?

I'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):
Private Sub btnImportInv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) andles btnImportInv.Click

I am working on a program that uses an SQL database which in terms has a dataset .xsd which im using. I need to be able to update my dataset so it can reflect any changes made during run time. I am using the internal data binding that vb uses so I am not doing anything manually.
I fill a table adapter with information from the dataset and table with this snippet of code:
Me.biweeklyTableAdapter.Fill(Me.DDSPayRollDataSet.biweekly, biwk.valpay)
A program that I'm slated to release, is (Hopefully with help) going to contain Auto-Updating.I've tried publishing using the microsoft Publishing that's offered in VS 2010, but i keep getting errors.I have an unlimited space FTP at my disposal, and i was hoping to do it through that.[code]Or, is there a better way to do Updating and Downloading? Also, for the First run, i would like it to be in an installer.

I have a program that has a variety of pick lists updated via an WCF process. For most cases, the pick lists are VERY short. The process I used for the update is overly cautious.The table comes in, then for each row in the incoming table, the matching row in the target table is found, if there is one, and each field is compared. This works fine for those short lists. The whole thing is done on a background thread, anyways, as changes are pretty rare.

This is the code for my 'validation' form, which reads stored numbers in an access database and compares them against generated lottery numbers to check for winners. It assigns divisions and prizes to each gameID from the table in the database and is supposed to write this information back to the database. However, I get an error on the very last line of code where I tell the data adapter to update the table in the database with the dataset. The actual error it gives me is "InvalidOperationException was unhandled". Here is my code (ask me questions for any clarification):

I am making a project for data entry on VB 2010. Database used is MS ACCESS 2007. In that there are buttons for next, previous, move first, move last, edit,add,delete,save,cancel.The problem is that when i run the code, and delete a record, the record gets deleted and next time i run, that record is not present but when i add a record or edit a record, at that moment it shows the updated record bus as soon as i close the code and run it again, the record is not updated.

In our project, we have 2 client PCs having their own local databases and 1 server PC who also have its own local database(.mdf). These three are connected through a local area network so I would like to perform updates to the client PC database from the server PC. There should be two types of update, one is that the server will send its entire database to the clients and overwrite the client's databases and the other is to append the changes made in the server database to the client database. I only want to use vb 2010 so I used the SQL connection class.
View 15 RepliesI have one DataSet and two forms, Customers and Efficiency. When I make changes to the Customers table (Delete a Customer for instance) It does not reflect the changes on the Efficiency table. The default form is Efficiency and I'm calling the Customers form from within the Efficiency form. I make the change in the Customer form, I then close the Customer form and call the Efficiency form back. The data is not updated on the Efficiency side until I close the application and re-open it. what code I need and where to inject this code?
View 14 RepliesI have a single table in a SQL Compact DB (*.sdf) and a Datagridview. When I put the datagridview on the form I connected it to the table in the compact DB. I also have a few button that, Deleted and Add a entry. Delete button obtains the selected datagridview row and resolve the record ID. It then deletes the record in the database. The record gets deleted but the datagridview does not show the update unless I restart the debug session. I make teh same cal to:
Me.TblTableAdapter.Fill(Me.Database1DataSet1.tbl) which is called when the form load that fills the datgridview..
I have a progressbar which receives the amount of Sub directorys within a main directory as a Maximum value and when i run the program It goes through the directorys to grab all the files within the subdirectory.
This is the code below which is updating the progressbar.Foldercount is an incrementer which increments by one for each folder it enters.
Dim percentage As Double = folderCount * 100 cirFolderCount.Maximum
cirFolderCount.Text = percentage.ToString
cirFolderCount.Value = Convert.ToInt32(percentage)
On the test directory which has 4 sub directorys I get a maxvalue of 4 and the min value is set to 0 The code above returns the value of 25.0 when entering the first folder which is correct (25% of 4 is 1),But the progressbar does not fill 25% of bar once this folder is processed.
I have a datagridview and 3 buttons (New, update and delete).When I enter the form and I make changes to the datagridview and I save them, everything works fine.After the first save I make some more changes and I hit save again I get the error:"system.data.dbconcurrencyexception concurrency violation the updatecommand affected 0 of the expected 1 records"

Me.TblEmployTableAdapter.Update(Me.PoolsDataSet.tblPools)
Me.TableAdapterManager.UpdateAll(Me.PoolsDataSet)
Me.StockDataSet.AcceptChanges()
Me.TblEmployBindingSource.EndEdit()
But the thing is, whenever i write something in my code e.g "retyping the Me.close". It goes back to whats in the original items in my database.

View 3 RepliesI'm loading a table from my database into a datagridview. Removing (multiple) rows from the database and the datagridview works great. Now I need to be able to add records directly into the database as soon as I add a new value into the datagrid.
- the id is the same ID as in the database
- the id-column is read-only
- the "datum"-column is where I want to add a new date (as soon as I leave the column it should add it into the database and the id should be added, without reloading the database) Adding the id (without reloading the database) is actually the most important part, but I don't have a clue how to achieve this.
I'm working on a project where users search for an item with it's unique number, which retrieves the data from a stored procedure, ordered by date in different rows.That works ok.
