Hi,
I'm pretty new to VB and I'm trying to figure out how to use the loop command until I select a command button. Can someone help me out with this easy question? Thanks.

Button in a Loop command? You don't. If your trying to wait for a button press in a loop, you're not following the event-driven programming model of Windows Forms.
What are you trying to do with this button click in a loop? Are you waiting for an OK or something?

I have a selection loop running. What I have envisioned is allowing the user to pick items out of a CAD window until the user selects the command button I labeled "OK". I hope I explained myself correctly.

Change your form so that when the user clicks on OK, the event handler for the button finishes the processing of the objects the user selects.

Exactly how do I do that? Sorry, I really don't know how that's done.

What are you talking about? The code you were going to run after the loop where you wanted to wait for a button click? That goes in the Click event handler for the OK button you wanted your users to click when they were done, right?

Yes, you're right, but what I'm looking for is what command needs to be typed following the Do Until to allow for the user to select one of the command buttons on the form. When I pass the focus to the application where the user is going to be selecting elements and when they're done selecting and try to pick the "OK" button I get an error message saying something like the application is busy, Switch To, and Retry buttons are my only choice.
Do Until ???????? - what command - ?????
Select Element code......
Loop
Forgive me, I'm new......
Thanks for your time and help.

You're not listening. You CANNOT do this at all! There is NOTHING you can put in this loop that will allow you to do what you want.
You MUST rewrite your form to do whatever it needs to before the user gets to select any element. AFTER the end of that function is where the user will select whatever elements you want them to, then click the OK button. In the Click event of the OK Button, then you can finish processing.
YOU ABSOLUTELY CANNOT RESPOND TO BUTTON CLICK EVENTS WHILE A LOOP IS EXECUTING.

ROTFL - this made my morning brighter.
However, can't he run his loop in a seperate thread and have a UI thread stop it ?

Hello there
I am building a deployment package. I have two types of setup one is for application and other for Database. for database I have an Exe which should run during admin setup. the problem is when I run the setup after compiiling it only runs client setup.
how to run admin setup as in dot net when you add the setup builder project it shows you two different types of deployment but runs only one.
what I need is .... user select either he is going for database setup or application setup during main setup.
any support ???

Admin setup in Windows Installer refers to putting components on a central server so that clients can install them as options, not to performing a different sort of setup like the situation you refer to, i.e DB vs client app install.
Although you can manually modify an MSI to support Features, doing so is a non-trivial process and requires considerable knowledge of MSI architecture.
The simplest way to accomplish what you need is to package your DB setup separately from the client application, and then modify the bootstrapper application to allow the user to select which install they wish to run.

How we can used sql command such as :
select max(debit), max (credit) from entries group by accountno
Im using sqldataadapter as bridge to database. When retrieve this statement from query builder (sqldataadapter1.fill) sure cant be placed into the dataset later because they are not same table design or schema.
How i can make used of that max(debit) or max(credit) value which have been grouped by accountno.
I have idea to select all data and put it into dataset and from dataset i put:
Dim dataTab As DataTable = DataSet11.Tables("Entries")
Dim deb As Double= dataTab.Compute("sum(debit)", "")
but the compute sum is not grouped summary, how can i solve all above problem and , "") sign is actually to filter, how to make use of that?
Thanks in advance.

Use a numeric index to access your columns, or do this:
LordLothar wrote:
select max(debit) as maxDebit, max (credit) as maxCredit from entries group by accountno
Then you can access them by name.

First of all VB6 apps has really an advantage over .Net apps because the overhead of loading the framework is not there. Then normally when a .Net app starts up the jit has much to do which slows down the startup time. At least the second can be reduced. Search for NGen on google. Its a tool coming with the SDK which lets you precompile assemblies which can reduce start up time greatly (depending on what exactly happens on your start up).
