VS 2008 Dataset Not Updating Local File DB?
Apr 13, 2009
I have created a local database using the DB wizard in 2008 express.I have created a table called users and I can access the sample data that I have entered into it using a windows form.When I try to add a new record things come unstuck. The record shows in the windws form as being present and the record count increases to indicate this. But when i check the DB itself there is no sign of the record.I am using the tableadapter method as outlined by MSDN. So the question is what am i doing wronghere is the code from the form:
Public Class frmS4
Private Sub UsersBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UsersBindingNavigatorSaveItem.Click
[code].....

I am creating a database application via visual studio, using VB.NET and with an access database. I've connected them and have been using them fine so far however I've had to make some changes to the original access database. I am unable to find an obvious way to update the current dataset object within the project from the new updated source file. My database has this new schema but the dataset has the old one so its causing conflicts. The only way I've found to do this in the past is to manually update the dataset with the changes I've made in the access file, so actually doing the same thing twice! Surely this isn't the only way? The changes I've recently made are massive so will take sometime to have to do it all again. If I delete the current datasource object and add it again, there are many errors left from the deletion. If I manually try to update the files, there's always some hidden ones I've missed. Ive found some sort of guide for updating the datasource via the dataset but what I want to do is the opposite!

I do not know much of datasets. I have created a local database with a table as per img 1 attached, and I use them in a simple drop down selector as per img 2. But I get the message as per img 3 , and I played around with the dataset, removing teh primarkey, etc.

I'm sure this is blindingly simple and I'm just being a nonce.I have a Dataset containing a single table. During my code's execution (this is a console application) I create a DataView to select rows meeting certain criteria as so

I 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.

i'm using a copy of visual basic express for my home projects. i'm just started one that is needing a local database, so i added one to the project and created the tables with with colums no problems.
i created an 'Admin' user straight into the database and use that to log in. i have also created an a form so that you can add other users and view existing users in a datagrid view.
the original source code i used was supplied in on this forum page:
[URL]
its all well and good, and works fine, right up to the point when i shut the program down and then re-open it the next day, all the users i created the previous day arent there anymore.
the code for creating the users is this :
Dim con As SqlCeConnection = New SqlCeConnection(My.Settings.Database1ConnectionString)
con.Open()

I found something very strange, in the data base explorer I modify the conection to the location of the data base(F:My DocumentsMy ResepteResepte.sdf) , but after raning the app. the path is back to what it was in the project folder and so the same in the selution window. It is set to Do Not Copy. How can I change this so that the IDE looks at the propper data all the time.

I'm trying to output a resource file to a physical file on my hard drive. Here is what I have so far from researching but I think I'm doing it wrong.
Dim ms As New System.IO.MemoryStream(My.Resources.File1) Here is how I would do it in VB6, but I'm trying to catch up with the times and move on to the new stuff.
Dim c() As Byte
Open Sysdir & "mswinsck.ocx" For Binary Access Write As #3
c = LoadResData(103, "Custom")

I need a simple method for a user to enter as many rows of data as they wish (probably won't exceed 50 in most cases and that's pushing it) and then store that data for retrieving the next time they want to reuse that list. I will also need to read the rows in for manipulating text in a file with those entries.
Would the best method to be to use the DataSet in VB Express 2008 and then use the DataGridView for allowing the display and entry of the data?

We have an app that tracks .DOC and .PDF files (and possibly other file extensions). It stores copies of them on a network share. I want to give the ability to the user to allow them to click the file in a listview, for example, and have that file open in WORD or ADOBE or whatever program is associated with that file type.

I"m completely stumped. I've looked here[url]... Changed my connectionstring appropriately. My dataset is fills with data. The Excel file already exists, but has nothing but a Header row. I can't understand why the dataset can't push the values to Excel. The only thing it's doing is inserting a bunch of rows. There's nothing so far indicates something is wrong. [code]...

I have a datagrid that I use to display data from a SQL 2000 table. I am trying to write back any changes the user makes to the datagrid data back to the original table but don't know the proper method to do this.
Here is the code that populates the datagrid:
Dim TheDatabase As System.Data.SqlClient.SqlConnection
Dim ConnectionString As String
Dim cmd3 As New SqlCommand
Dim Adp3 As New SqlDataAdapter
[Code]...
I could use some suggestions on how to code the write back command that will allow the user to change the data in the datagrid and have those changes be written back to my tAdjustment table.

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:

I have a simple one-line dataset which exists on a form. I do not want to add additional lines or delete. I just want the user to be able to save if they need to. So I added the dataset, dragged the fields onto the form and deleted the unnecessary icons to have only a "save" icon. I also changed the property of the database to 'save if newer' but I am stumped as to why it is not saving. Every example I see looks so easy-peasy and when I do it, I get the following error:[code]The "save button" didn't have code when I dragged the bindingnavigator to my screen so I used the code in the video as a guide to structure mine and it should have worked. :/

Right so I have my piece of software, it's complete (for now) and I want to get the final version of it and send it away. Once sent away the only way I'll be able to update it will be via a DVD or maybe if they download the update online.This is what I wanna know: I am just using the .exe file from the Debug folder, is this the right way? Do I need to compile it first and do a proper saving of the .exe file?Is there a way to specifically do the updating of the .exe file that is somewhere else? At the moment my thoughts would be to just copy the .exe file from the debug folder and wack it on a disk with a bat file that xcopys it. Is that considered the right way to do it?

I'm willing to compare a textfile (whatever) which contains a few lines of text. After the comparison it should download and replace the "changed" folder/file. E.g.
(Local txtFile)
maps: 1.0.0
db1: 1.0.0
db2. 1.0.0
(Server txtFile)
maps: 1.0.1
db1: 1.0.0
db2. 1.0.0

I am having a problem updating an access database with new information from an updated dataset. the database consists of 4 columns: User_ID, Login_Name, Password, Access. The following code makes a connection to the database, fills a dataset with the data from the database, reads a txt file with user name and passwords, and should update the dataset and then the database. However, I keep getting an Syntax error on the INSERT INTO statement on the datest.Update(dsUser,"User") line. I have found multiple posts on here showing the correct syntax of how to update a database, but I can't seem to get it to work.

so I was originally having problems even saving the data, but I can now get it to stay in the dataset, and when I switch to another page it stays there when I go back to it. Although when I close the form and reopen it, the changed data has not saved. I know that it is because I have only updated the dataset and not the database, so was hoping someone could give me pointers of how to approach it.

I have added a SQL Server datasource through the wizard. I created my forms which were bound to the dataset. Is it possible to change the datasource and dataset names while updating the dataset the binding controls of the form?
For instance, Server 1 has DB1 and Server 2 has DB2 (DB1 & DB2 store the same information/tables). Is it possible to keep the forms and only update the binding information if I want the forms to use DB2?

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.
