VS 2010 Updating UI From BackGroundWorker_ProgressChanged

Apr 16, 2011

I posted this initially, but moderator deemed that it belongs to WPF cause I had the keyword WPF in the title. But I have tried to recode this Windows Form to test out the behaviours. Unfortunately (or fortunately?), the result was the same. *Italics sentence was changed to suits Windows Form*

VS 2010 Updating A Table?

Apr 10, 2011

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.

cmd.CommandText = "SELECT HydroID FROM GIS_Hydrography WHERE HydroID = " & dr("HydroID").ToString
rObj = cmd.ExecuteScalar

VS 2010 Updating Access Db

Aug 12, 2011

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):

Database Updating Through A Network Using VB 2010?

Feb 24, 2012

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.

VS 2010 : Progress Bar Not Updating Properly?

Jun 19, 2011

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.

VS 2010 Updating A Database In A Datagridview?

Apr 6, 2011

I have an existing database that Im using. I managed to update the database to whatever changes I do to the items in the datagridview using the code

Me.TblEmployTableAdapter.Update(Me.PoolsDataSet.tblPools)
Me.TableAdapterManager.UpdateAll(Me.PoolsDataSet)
Me.StockDataSet.AcceptChanges()

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.

VS 2010 Updating Database Using Datagridview?

Feb 22, 2012

I'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.

VB 2010 Concurrency - Updating Entry In One Instance

Mar 29, 2012

I am writing a program that makes use of SQL databases using MSSQL Express 2008. I've just written code that updates data in the DB, but I noticed when I update an entry in one instance of the program, and then try to update the same entry in a second instance of the program it goes through. What I want is concurrency so if the entry is different from the original, updating is not allowed.

Here is the code I use to update entries
VB that calls the class and checks for errors...
Try
If contactIsValid() Then
Dim getresults As New groupfilladd
If getresults.updatecontact(myParent.itemfound + 1, fnameTxBx.Text, lnameTxBx.Text, _
