I am trying to familiarise my self with connecting to SQL and manipulating data and I seem to have fallen at the first hurdle I am trying to programmtically connect to a database and fill a data grid with a dataset.

Dim cnnOriginalFileLo As OleDbConnection = New OleDbConnection

Forms :: Data Base Master/detail Consistency VB 2008

Mar 15, 2010

In it's simplest form, I have two forms a master form and a detail form. I added the data source from within the ide.

Data> add new data source database>new connection > microsoft sql server database file. Selected table etc.

From the datasources tab in the ide I dragged the grid view onto the master form. dragged the detail view onto the details form.Independently both forms work fine, However if I load the master form first and then load the detail form when the master dgv is clicked the problems start.

[code]...

All variables are correctly declared and the details form works fine, the correct record comes up and can be added, edited and deleted.I then save the form by clicking on the save icon and close the form but changes made to the details form (e.g. additions or deletions) are NOT reflected on the master form until I close and rerun the application. guess it's just a matter of refreshing the right control(s) on the master form but I cant seem to find it.

VS 2008 : Updating A Data Base File Via A DataGridView Control When Called From Another Form?

Jul 24, 2011

I am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .

The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :

Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :

Form1.Button1.PerformClick()

but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .

Which Is More Secured / Iterative Salting Or Encryption Methods?

Jun 13, 2011

I have a question in security programming. As all of us know, when we have a database with passwords or anything sensitive, we would like to encrypt it so it is not readable by other. Now I want to know, which of the method is secured or less secured. Is it Iterative Salting (1000x iterative) or Encryption method such as SHA 256, MD5, and all others. Kindly give me your opinion on this please.

VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?

Jul 24, 2011

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .

The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

Aug 9, 2011

I need to connect Access 2007 Data base using VB.net application. (This is an AddIn working underAutodesk Inventor 2012 64 Bit).When I use a ODBC DSN (under C:WindowsSysWow64) I need to compile the application with targetas x86. But Inventor 2012 64 bit needs target as x64 or Any CPU. So ODBC - DSN not working.

Provider=Microsoft.ACE.OLEDB.12.0; Data Source=c:database.accdb;Jet OLEDB:Database Password=password;"
This also gives the same error.
