Dim DS As New DataSet
Dim query as string = "SELECT * from DAP"
Dim OLEConn = New OleDb.OleDbConnection("connection string goes here")
Dim adapter As New OleDb.OleDbDataAdapter
adapter.SelectCommand = New OleDb.OleDbCommand(query, OLEConn)
adapter.Fill(DS)
THIS IS THE POINT OF TROUBLE...
???? DS.Tables().Clear() ???? 'not this
???? DS.Tables().Remove() ???? 'not this
I want to delete the table "DAP" and I know the code above is not the correct way to just connect to a database, select a table, then delete the table. Does anyone have a snipet of code that 1. connect to a db. 2. selects a table. 3. deletes the selected table?
Thanks.

Dim query as string = "TRUNCATE TABLE DAP"<br />
'or if you need to log the action - but truncate will be faster<br />
'Dim query as String = "DELETE FROM DAP"<br />
Dim OLEConn = New OleDb.OleDbConnection("connection string goes here")<br />
dim cmd as OleDbCommand = New OleDb.OleDbCommand(query, OLEConn) <br />
cmd.ExecuteNonQuery

in SQL (structured query language) there is a command that deletes the whole table: DROP Table (tablename) - I'm not sure the exact syntax of the VB.NET version of that command, but that should give you a place to start. Also you might check out the MSN group at http://groups.msn.com/VisualBasic/ (go to "Message Board" in the left frame and they have "Databases" and "VB.NET" message boards). You have to get a (free) msn passport in order to join the group, and then get approved by a manager or assistant manager (I am an assistant manager, so once you get the Passport, e-mail me @ rhenerlau@hotmail.com and I will approve you.)
Hope this helps!

con.open

Hi,
I'm inheriting a base form we have written that mostly handles button arrangements. Every time I disable/enable the derived form it gets moved behind any other windows that are currently open. There is no code in either form that should be causing this behavior. We are not overriding or altering the enabled code in the base form in any way. Has anyone else encountered this problem or know how to fix it?
Thanks,
Joe

They are service applications, which VB6 cannot create. There is a seperate application that communicates with the service app that handles the user interface when someone logs in.

Hold on there Gnome boy, you CAN run VB6 apps as services. If you Google "VB6 Services" you'll find tons of examples of this. Such as....... http://www.vbrad.com/pf.asp?p=source/tip_service_vb.htm

Hold it there, wiseass. Read the post again and the history of his other posts concerning the very same topic. The link you just gave me, I originally posted as my first or second reply to him!
Now, I said that VB6 could not generate a windows service. This is exactly right! I know perfectly well that you can take a VB app and run it AS a service within a service WRAPPER, but you can't generate a TRUE service app with it. The VB6 compiler will not output the correct service entry point...

how to make a process a service in VB.
i am seeking help in VB to make my application's exe run without being tirggered just like worms.
The payload of my application is Just MessageBox stating "Welcome From Usman".So there are two main issues ,
1)How to execute exe without tirggering it
2)Where to place and how so that every time windows starts(not user logs in) , it executes it self and show the message box.
I hope that you will help me.

A windows service has to be installed. VB6 doesn't come with anything to do that. There are, however, 3rd party utilities that do. I already posted a link for you to follow that contains instructions on how to do it.
Next, you have a huge problem that you can't resolve. Since your application is running as a service, it runs under a completely different desktop than the one the user sees. This mean, that unless your service is tagged "Allow interaction with desktop...", the messagebox you put up will never be seen by the user.
Now, having solved that little problem, you have a second problem. You said you want to put up a dialog box while no user is logged in. Not going to happen. Since there is no desktop when a user isn't logged in, there's no way to put up a visible message box.
On top of that, your VB6 app is not a true service. This means that you don't get the notification messages that the user session is being terminated or started, so you can't tell when someone logs on or off.

Easy. Check into the Process[^] class. The only way your going to pass your VB program variables to the external .EXE is to pass them as command line parameters when you launch the .EXE.

Start by opening Visual Studio, click on New Project, open the folder for VB.NET, double click on Windows Service in the project templates pane. From there, read this[^] for a walkthrough on how to create one.

I have a question about programming the DataReport in VB6.
Do I need to use the DataEnvironment to link a database and table to the report or can I create a connection and recordset in code. I'm asking this question because I wish to create a report based on a user's query not a static query.

is it possible to show an html webpage inside a vb6 textbox...or other control?
thank.....

Not in a TextBox. You'll have to add a WebBrowser control to your form and use that to diplay the page. Just add the Microsoft Web Browser component to your ToolBox and drop one on your form.
