I've been fighting with this for a solid day now.
I want to populate a dropdownlist with items from a table in design mode.
seems like a simple thing, but I can't make it happen. Could someone please
aim me at some good documentation on this?  Sorry, I'm a dot.newbie but not

I actually have 2 questions:
1)  Is databinding the fastest way to load a listbox from sqlserver?
speed is crucial and I want to make sure i'm populating it the fastest
way i can

I have the following code defined:
<StructLayout(LayoutKind.Sequential)> Public Structure Callbacks
       <MarshalAs(UnmanagedType.FunctionPtr)> Public OnError As
OnErrorDelegate

i am trying to set the text of the row header in a datagrid
i found several examples
in all cases the TopRow() property is not recognized by VS.NET
any help appreciated!

I have seen applications that run a "special" program when they are run for
the first time.  I need to allow the user to choose a file location the
FIRST time they run the app.  I am not sure how to do this.  Any help would
be greatly appreciated!

Does the textbox in vb.net (alllow input multi-line ??)
In vfp, there is "editbox" , which allow user to input several lines data
and save in the table 'as memo field'
However, I can't find the similar thing in vb.net and sql server (ntext ?)

This should be simple, when I use the code:
PictureBox1.Image = Image.FromFile("MyPic.jpg")
how do I "unload" it so I can move or delete it?
Thanks yet agian,

Is it possible to use an array of structures as a datasource for a control.
ie
dim structure structtest
   dim str1 as string

why can't i set the font of a button to bold at run time (it's read only), i
can only set at design time.  it can be done in vb6.
thx

I tried sth i did b4 in VB, now in VB.NET, but since the form is created
every time, the following code would not work because MsgBox.Visible is
always false, any idea?  Thanks!
Public Function MyMsgBox(ByVal strMsg As String, ByVal MsgType As Integer,

Heresy  ?
  I successfully and simply passed data from one form to another. (this
after days of frustration at the methods I read of and that felt to me to be
verbose and over exact)

Can someone post a clear example of how to change the background color
of an individual datagrid cell for a Windows desktop app? (preferably
in vb.net)
I found some code on how to do this when the user clicks on the cell:

I have a small installation app that I'm building. The user can specify
an install path at the command line. How can I ensure that something
they put in is valid?
What I'm NOT looking for is determining if a path exists. I can

is there a simple way to get the currently selected row's key in a bound
data grid in winforms? thanks

OK I've been staring at this code all day and still with everything I
have tried I cannot figure out two problems I am having.  Once is why
the space limit for the directory I create in the code fails.  Second,
why the data reader is reading every other record.  Here is all of the
