When he types the second letter, it displays all records whose last name starts with those 2...
OK, I deleted the Patient.mdf in Server Explorer.
Then I opened a New Connection and browsed to the .mdf file under the output directory (\bin\debug).
Now I can see the new column in Server Explorer.
But, how do I get it to appear in Data Sources of Solution Explorer?
>what version sql you are using?
I am using SQL Express that came with Visual Studio 2005 Professonal.

Dim columns As DataColumnCollection = Me.PatientDataSet.Patient.Columns
If columns.Contains("CaseNbr") Then
MsgBox("'CaseNbr' column already exists" )
Else...
I added the following statement to my program:
Me.PatientDataSet.Patient.Columns.Add("CaseNbr", Type.GetType("System.String"))
But it did not do anything.
I added the statement as the first command in the Form Load routine:
Public Class Patient
Public Sub Patient_Load(ByVal sender As...

Visual Basic 2005
I used DataSet Designer to add a column called "Case#" to an existing SQL table.
The table is used by a DataGridView in a VB 2005 program.
I got it working on my development computer in debug mode.
Then, when I installed it, I got an exception "Case# is an invalid column"...
OK, I muddled around until I got it working in debug.
Then, when I installed it, I got an exception "Case# is an invalid column" and none of my data records appeared.
Visual Basic 2005
How do I go about adding a column to an SQL database.
Everytime I did it in the past it was a disaster and I literally had to start all over again from square one.
I would go into Dataset Designer to add the column then I would have all kinds of problems with the form that...
Visual Studio 2005 Profesional:
I am using Windows Installer to create a Setup.msi.
I want users to be able to download a 30 day free trial of my Windows app from my website.
The download worked fine on my development computer.
When I tried it from a friend's computer,
with my download button...
