Yes, however the exact query depends on the database.
For example, in SQL Server 2000 the query
SELECT * FROM INFORMATION_SCHEMA.TABLES gives you your starter for 10.

I need a project proporsal for any small system I can undertake as my college project. Others have been doing projects like Accounting systems, something to do with Intranet etc.
well I would prefer mine to be coded in VB6 if having a database the it should be SQL server database with something to do with the ineternet or intranet. please guys just send me anything. Any project that can be run in VB6.
My email is mtheprince@yahoo.com
Thanks

My first piece of advice is not to do this in VB6. VB6 is almost completely obsolete now. It was replaced in 2002 by VB.NET (almost 5 years ago, during which time versions 1.1, 2.0 and 3.0 have been released)

Be creative, there sure is something you can think of to build. My advice would be to go for either C# or VB.NET, since these languages are modern and the framework is new and better supported.

Its just that I dont have VB.Net as of now and need to get started. And the project as well. I can be creative but most of the projects are taken and need something new

You need to either read up on the Word file format, and write your own code to read it ( good luck ), or use Word itself, which can be controlled via COM and ( in recent versions ) .NET.

See my last post. If you want to control Word, you need to google for it. To be honest, I've not done it, I just know it can be done.

Can anyone tell me how to program to disable Outlook Security settings and avoid security warnings like "a program is trying to access e-mail addresses"?
Many thanks!

With great difficulty! As far as I'm aware it cannot be done in .NET. It can't be done in VBA. It can be done using MAPI, which in turn can only be programmed directly from C/C++ or Delphi.
I had to work around this issue a few years ago and I did it in C++. Given the total problem context it wasn't at all straightforward - took a couple of months to figure out!

I am writing a vb.net code, and I seek an advice as to how to programmatically simulate a click on a certain item in a certain listbox (where my cursor is not located on that item).

You can directly call your Click EventHandler.

Let me more specific. In my click evenhandler I raise a mouse even (right click), but for that the mouse should be located on the right place in the listboc, that is in a certain index, while I call upon it from another location in the code (things are executed programmatically).

Hi
can someone tell me what wrong with my code i get the nullreference exception I know its something obvious but still new to .net
here is the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button1.Click
MsgBox(Spot(0).ToString)
End Sub
Function Spot() As Array
Dim ObjArray As Array
ObjArray = Nothing
Dim Obj1 As New Object
Dim Obj2 As New Object
Dim Obj3 As New Object
Obj1 = "Hello World"
Obj2 = 69
Obj3 = False
ObjArray(0) = Obj1 <-this is where the null reference is getting thrown
ObjArray(1) = Obj2
ObjArray(2) = Obj3
Return ObjArray
End Function
thanks everyone =)

Well, first of all, why do you want to create an array of all different types ? That kind of sucks.
Second, never use MsgBox, or any other things that exist only to make VB6 coders feel warm and fuzzy. Use the .NET stuff, such as MessageBox.Show. In this case, it doesn't matter much, but it's a good habit to get into.
Have you stepped through the code, to see what's happening ?
thedom2 wrote: ObjArray = Nothing
If your array object is 'nothing', then it's not an array, is it ? You would do better to use a dynamic container such as ArrayList. Either way, if you want to have an array with 3 objects in it, you need to call new to create it. You've done the opposite, you've told the compiler that there's no memory to assign yet, and no object exists.

well ultimately i wanted a function that output 3 items(hence the array)
when i try the below line
dim objArray as NEW array
intellisense tells me "cannot be used on a class that is declared 'mustinherit'"
the objArray=nothing was me "trying" to debug/test the fucntion(that didnt work)
any suggestions oh wise one

worked it out this is the code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'this calls function and select 2nd array element
MessageBox.Show(Spot(1).ToString)
End Sub
Function Spot() As Array
Dim ObjArray As Array = Array.CreateInstance(GetType(Object), 3)
Dim Obj1, obj2, obj3 As Object
Obj1 = "Hello World"
obj2 = 69
obj3 = False
ObjArray(0) = Obj1
ObjArray(1) = obj2
ObjArray(2) = obj3
Return ObjArray
End Function
Christian you cant actually use new keyword on array member well thats what i read on msdn. you need to use createinstance to get the thing in memory and work with object. thanks for your help anyway

You typically wouldn't do this. In C# you'd do it like this
object [] ObjArray = new object[3];
I have no idea how it's done in VB, but I'm sure there's a way.

Indeed there is
Dim myArray() as Object = new Object(3){}
