Do you mean the datatable ( which I believe you can search with SQL to get the row you want ), or the grid that displays the data ?

I have a tabbed form and all the fields from the SQL database are displayed in various textboxes,comboboxes,checkboxes,etc... (no datagrids). I have a datatable,dataadapter,currency manager,and datview for each of the 6 tables in sql. The "lead table" is the one that if they type in the ID number then I need to move to the record that matches or closest match. I can do it using the filter method, but that will make the current view have only 1 record and I can not move next or previous. Thanks

You want to have multiple users on a database based app ? The obvious way is to store usernames and passwords in your database, and give each user an ID and then use that ID through the database to record what belongs to whom.
If you want users to be able to do different things, then you need to add some code for permissions as well. It's best not to use multiple logins on the database, as it causes .NET connection pooling to not work as well as it otherwise would.

I have two things (maybe one)that I am trying to work on, and the second one is escaping me HELP!!
Here are my questions:
1. Write a standard windows application that minimizes to the system tray area. Double-click to bring it back, right click for menu. E.g outlook 2003, the volume control...
2. same application or seperate. Give me the same information and similar layout as you get when you right click My Computer and select Properties. Only the General Tab!!! Don't worry about anything else.

I don't see anyone writing the code for you.
Basically, I assume you're going to use this control online ? If not, where will the info come from ? Getting the data is the only sticking point, the rest is pretty trivial, any tutorial on user controls will help with that.

I used Visual studio .NET 2003 to create the sql database, and now I need to know how to import it into frontpage 2003 so I can use it with my webpage that I have created.
|
|
|
|
|
Frontpage ? I'm not sure that Frontpage does that, I'd have thought you needed to use asp or ASP.NET. I could be wrong, but either way, I think this is the wrong forum to be asking in - try the web development forum.

I have a datagrid with 2 columns, 1 is template column with a number of fields in it and the other is a delete button.
In the template column I have a drop down list that is loaded with a dataset. What I need to do is update a lstbox with data based on the selected value in the drop down when the selected index is changed.
How do I trigger or catch the OnChange event for a drop down in a template column?
Thanks for the help.

hi,
Can any one tell how to popup a form in vb.net
|
|

The simplest way to do it, if you wanted a dialog window is:
Dim myDF As New myDialogForm
myDF.ShowDialog()
If you want something more specific, you'll have to ask a more specific question.

There's only a bazillion different ways of doing it. Depends on how you want your data displayed (datagrid, textboxes, drop downs, ...), where it's coming from (Access, XML, SQL Server, ...), and how you want to interact with it (read only, editable, paging support).
You've got to be more specific when asking questions. It's really difficult to answer broad question likes you've asked here. I get the feeling that your just asking what the possibilities are and don't have a very clear idea for any one project your working on.

I have created the following in VB.Net2003:
I have a working form that I think has all necessary properties, methods, and procedures to do what I want it to do.
In other words, I have it so that it will appear when I press a button on another "parent" form, and will close when I click its close button. I want to be able to create many instances of this form from the "parent" form and I want them to work independently and close independently, but be able to communicate back and forth (send and get strings and other objects) with the "parent" form. I would also like them all to close, each having the chance to save information, when the "parent" form is closed.
I think that in order to do this I may need to do multi-threading, making each new instance in a new thread - but I don't think I want to go through multi-threading. Would a collection work?
Any help on either of these concepts or anything else that you might think would allow me to accomplish this would be greatly appeciated.

really no.
well it may depends in some special occasion that a separate thread would be needed, depending on the thing your form do, but generally not.
There are many way for doing it, anyway the basic solution to a have a Myforms() As Form in you BIG application and when the user wants a new one
Redim preserve myforms(myforms.length)
Myforms(myforms.lenght-1) = new yoursmallform()
myforms(myforms.lenght-1).show
and .. well for the data exchange with the parent form.. i think here also there are many way.
i just don't know.. i think after all there is some way across the .net a system for the forms to communicate... between the many ways i see for the comunications 2 are interesting in my point of view.. one is with a tcp/ip loopback connection (you may also use a small library of mine, posted here on codeproject, for doing this), but this is definetly not so efficent.
a better way (considering that you don't want to loose yourself into the .net) may be simply implement your event that may be easily thrown by the small form, and easily captured from the big one.
didn't you try this?
