Store An Access DB In A .Net App?
Sep 15, 2010
I have a VB.Net app that uses an MS Access 2003 Database. In my connection string, I'm utilizing the "|DATADIRECTORY|" construct (see code). cnn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DATADIRECTORY|MyDB.mdb;User Id=;Password=;"When I run my program, I'm getting the following error message:"Could not find file 'C:indebugMyDB.mdb'"
In order to use the "|DATADIRECTORY|", where do I need to put it within my Project. I basically want to deploy this app on stand-alone PC's. I guess a more simpler question would be: How do I deploy a single user application that uses an Access Database where the database location will go wherever the user specifies when installing the application?

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

I don't know if I can have several same forms to do the manager jobs, ACTUALLY THE STORE VALUES ARE DIFFERENT(those forms can have the independant data values to store into the forms), like if I can have the datagridviews to store the different values? SO,MY QUESTION IS if I can have several same forms(FROM ONE SAME FORM), and can store different data values into the forms with vb.net & access, OR I HAVE TO CREATE SEVERAL SAME FORMS.

So I know it's possible to store Users and Roles on SQL server but I was wondering if it was also possible to store the access rules on SQL Server. I've searched but I can't find anything.
Our auditor requires us to run reports that tell us which users have access to which websites. Currently I am parsing each web.config file to see which users/roles have access, storing that in SQL server and running a report off of that but I am hoping there is a better way.

how to store a hash in my Access Database. Now I have generated a hash by salting a user password with the User ID (not highly secure I know, but plenty for my purposes). I have also stored the hashed values in the database as Base64 strings (manually, I haven't yet developed the module to do that automatically), however, when I go to retrieve the hash from the database I receive the hex code in place of the string. This is the code for the login button:
Sub prcLogin()
'Log User in
Dim ds As New DataSet
Dim blnCorrect As Boolean
[code]....
But when I run this instead of returning a value like "rlzhYoiO4+vpdJdsrFq5Sj9VBJ+FFYhIg9V5+z+jeNI=" which I stored in the database, it returns a value like "5C6BED0D94

Basically i am trying to create a programme, which needs to have some authorisation.
When the application starts up, it starts straight into the login screen.
I want the Username and Password textboxes to read the database and if they match then progress to the next form but if they dont match then a message box will appear.
I also want to create groups of people so if a certain group of people log in they go to a certain form and if the another group of people log in i want them to go to a different form.
Also i want the password box to be * instead of visable text.
dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
dbSource = "Data Source = D:/Users.mdb"
con.ConnectionString = dbProvider & dbSource

If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.

Testing out a VB.net prog in Windows 7 that works ok in Vista and earlier. The users can set various options and save them for next time. In pre Vista this goes in the program directory in program files, in Vista it is transparently put into the user's virtual store.However, in Windows 7 trying to save the file gives an access denied error although the virtual store exists as for Vista and other apps appear to be using it ok.
