What Is A Good Way To Save A Dataset For Another User
Jun 16, 2010
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

When the user clicks an "Edit" button on my form, I want a box to come up which allows the user to edit a DataTable in a strongly-typed DataSet. What's the best way to do this?

I'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

I was developing my own project in the university so what i am stack is to have save button which firstly validates what the user enters the form. for instance if the user skips the text fields, i wanted to restrict the user to fill all the form and when he completes, the save must be accomplished.
Here's the code i was trying to put but i was having problem saying the windows.forms.etc is unable to convert the save as Boolean and something like that.
Dim success As Boolean
Private Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click

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.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

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?

I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.
Here is my code so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Grabs data from excel sheet and stores it in datagrid.
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim con As New OleDb.OleDbConnection

I have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.
This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure
[Code] .....
De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.
That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?

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?

I have a manually created a dataset (dsPickingList) that I add data too as the user inputs data on a form. There is a datagridview on my form of which it's datasource is set to dsPickingList.What I would like to do is spot if a user deleteds a row from the datagridview and update the dataset (dsPickingList) as it is ultimatly this dataset that is stored to the db and printed, not the DataGridView.[code]This is why I need the action from the DataGridView to update the dataset

I had an Excel spreadsheet which I put in MS Access (database). I then took that database and used that as a source in VB to create a GUI for. In VB I have an input text box to search and pull of different fields. I created some queries for searches in from the text box. I have have a dataset view of the data which has the binding navigator (add, insert, save).
The problem I have is that when I hit the '+' for add to add information and then click the 'save' button in the binding Navigator, the information I put in does not save. I check this by exit out of the program run (debug to open the app) and then open it back up to search and/or check for the new information I put in. My overall goal is to create to publish the final code and use an a standalone program.
Also, as another option,(I would like to learn) Is there a way to map VB directly to an Excel file to have the user input information and save to the excel file.
