Access doesn't support stored procedures.
It does support stored queries, if that is enough for your purposes. (It's basically a stored procedure that is limited to a single query, and has no other featuers like flow control commands.)
As such, stored queries doesn't add much, so it's mostly a matter of taste if you want to use them or not.
Experience is the sum of all the mistakes you have done.

Hi there VB Pros i'm doing a project that requires to encrypt and decrypt files.
I need to create this algo from scratch.
Anyone has any clues as to how to do that?? 
|

|
|

How complex does it have to be?
You could use a simple character replacement method, based on a string provided by the user or some other source.

Got your message. Does not have to be complex a simple encryption algorithm to encrypt and decrypt files.
The button sub routine will contain the algo when the user clicks the button the file gets encrypted.

Where does the requirement that you do it from scratch come from? Its 99.99% likely that if you write your own algorithm it won't last 15 minutes of cryptanalysis....

Hi,
I also got this error, when i try to run my already created application on my friends PC, the problem is he has the Office 2000 in his pc installed.
Do one thing uninstall the office from your pc and install the XP or higher version of office.
Hope this will help you.

thanks alot for u advice..
yes, it is cause of my excel is old version..
now upgrade to office2003.. it is ok...

yogesh_kumar_agarwal is right!
You'll probably need to use 'Late Binding'
instead of 'Early Binding'.
Therefore do NOT use the MS Excel ObjectLibrary and
Imports Microsoft.Office.Interop.Excel.
'Google' for MS Excel, Late Binding & VB.NET and
you'll probably get your answer.
Good Luck.

thank you answer ...
i can solve it now, by update office to 2003

That's odd. There is a managed API, but it's very limited and buggy. You can use it for simple video playback, etc, however.

Hello there,
I have a “load” event on a startup form with a notifyicon that starts a timer on another form to execute code at a given time from settings in My.Settings. This works well.
Then I make use of a login form to stop the timer and load the form where the timer is on and adjust My.Settings via numericupdowns to change the given time to execute the code and use a button to start the timer again.
The problem is that it is not using my new settings. I tried My.Settings.Save() – which only works when I restart the app.
The timer is stopped before I adjust the numericupdowns and it does start again on the button exit.
Help please

Did your code reload the settings after you Saved them? You might want to check out the Reload method of My.Settings.

Hi every one
I had a application in VB6 which we migrated to VB 2005 Express
The application is designed to access a centralized DB server (Postgres 8.2) and all the clients will have there own copy of the application
In my Vb6 application I was able to connect to the DB using ADODB connection and ODBC data source / DSN, this gave me freedom that no matter where the DB server is located I can just configure the DSN in each client machine and the application will work
Now when I want to do the same with .Net I am not able to do the same.
I had tried using Npgsql and Data.OleDb.OleDbConnection
But I am not able to succeed
Can u plz give me an idea how to do it, any sample or reference if possible?
Regards
Nishkarsh

Did you look at these options?

some error information would be useful, I would expect the OleDb connection string to work but I note there are some caveats on installed components with the connection string. They also supply and ODBC method you may be more comfortable with.
Never underestimate the power of human stupidity

All the options given in the link involve server IP, but i wanted to do it with using DSN
can u plz send a example to use ODBC or OleDb with DSN.

I am have problems adding records to an array. I am using a structure and an arraylist
Code Snippet
Public Persons As New ArrayList
Public Structure Person
Public First As String
Public Last As String
Public Home As String
Public Work As String
Public Mobile As String
End Structure
and the next block is to add a record to the list
Code Snippet
Dim p As New Person
p.First = txtFirst2.Text
p.Last = txtLast2.Text
p.Home = txtHome2.Text
p.Work = txtWork2.Text
p.Mobile = txtMobile2.Text
Persons.Add(p)
lstPhone.Items.Add(p.First + " " + p.Last)
The above code works but the trouble i'm having now is I cannot append to the array or save it.
Can anyone help?
Thanks all
Regards

This code works just fine.
I'm not sure what type of control lstPhone is, but this below code will work just fine.
Question: Why are you using a Structure instead of a class?
Question: Why are you using an ArrayList instead of a Generic List(Of Person)? This would provide a type safe collection.
Public Structure Person
Public First As String
Public Last As String
Public Home As String
Public Work As String
Public Mobile As String
End Structure
Public Class Class1
Public Persons As New ArrayList
Public Sub New()
Dim p As New Person
p.First = "hello"
p.Last = "There"
p.Home = "555-1212"
p.Work = "411"
p.Mobile = "900-555-1212"
Persons.Add(p)
' this will work just fine
'I'm assuming that lstPhone is a Combo Box or List Box?
'lstPhone.Items.Add(p.First + " " + p.Last)
End Sub
End Class

Sorry Karl I made a bit of a boo boo here.
I forgot to add the fact, i'm using a .csv file to append the new persons data to. I might get a thread going properly one day.
