VS2008: Back-up Database Using SaveFileDialog?

Oct 8, 2011

I think my problem in my code is the savefiledialog1. I tried running the code without it and it works. There's no error.

I also remove the if condition in the .ShowDialog and it worked. But when I press the cancel button, the code still runs.

vb
Private Sub butBackup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butBackup.Click

Feb 8, 2010

I would like to manually access and update an Access Database without using bound user interface objects

For example:

2) Create a Dataset of one of the tables in the database (eg: Contacts)
3) Loop through all records in that table and edit one of the fields
4) Update the table while completing the edit of each record.

While the code for doing this in VB6 is eazy peazy the code for doing it in VB2008 escapes.

Make User Interface To A Database With Visual Basic (vs2008)?

Feb 4, 2011

Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?

Don't Commit Changes Back To Database

Jun 21, 2009

[code]So both methods seem to step through fine but don't commit the changes back to the database. This function is my only 'edit' function. It needs to look for the datarow which is to be edited. Edit it and then save the changes to the database.My other two functions create datarows and work fine. This one I just can't work out. I have a dataset with two datatables. This is running as a web service. Database is MSSQL.

I am having a problem with an application that displays data in datagridview depending on a selection from a combo box.The problem occurs when I want to write the data back to the database.

I get the following error:"Update unable to find TableMapping['Product'] or DataTable 'Product'."

Is this because the table in the dataset is filled in a private sub? If so how do I make it public?

Any ideas what is wrong. Code is as follows:

[OOD] Class Design For With Database Back End

Feb 6, 2010

I was hoping that I could get some guidance from some of you guys on Object Design with Database back ends. I am trying to build what could be considered to be my first full scale application, which is a student tracker (simplification). While I have a reasonable idea of how I would go about designing the classes for the system, the bit that I don't know how to do is, how I would go about getting the data to and from the database.

For example with my other applications, I have done a couple of things;

1) Gathered all the data when the application started up, creating the objects then. Then when the application closed sending the data back to the database.

2) Have the code which deals with getting the data in the specific class, so the student class for example would take only one constructor argument which would be the studentID, then the class code would connect to the database and populate the object fields as appropriate.

3) Variations of the above. I have also looked into LINQ, which seems like it would be very useful if you don't expect your classes to deal with any business logic and just data, but I suppose it would be possible to create a wrapper class that would include the business logic.

DB/Reporting :: DataGridView Back To SQL Database Through Stored Procedure

Feb 18, 2009

I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]

Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.

I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.

If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.

Possible To Have An Access Back-end Database Available For Multiple Users On The Same Network?

Nov 5, 2011

I am developing a Visual Basic .NET application to be used by the staff of a small training centre nearby. The front-end (UI, menus, etc.) will all be in VB .NET, and there will be a back-end database for storing all of the required data, such as student records and meeting information. What I would like to know is if it's possible to use a Microsoft Access database for this purpose, and have it accessible by all the staff in the centre (on the same network) at the same time. For example, would I be able to put the database in a shared network folder, and have a copy of the VB application on each PC that would all be able to read/edit/add to the database?
