I don't think it's possible in VB6 because it doesn't support reflection.
In VB.NET, this is not a problem.

I think an array of type Forms could be helpful (if I have got you correctly):
dim forms() as Form
....
redim preserve form ( ubound(forms) + 1 )
set forms ( ubound ( forms) ) = new form
...
hope it helps

I have got the solution ...
Forms Collection is used for Loaded forms in memory
so
Forms.Add(rs("FormName"))
for each frm in forms
if frm.name="Form2" then
frm.show
end if

Dear guys
How can I change background color of toolbar and MDI form?
Thanks in advance.

To change Background color of MdI form
Do not set isMDIcontainer property of the MDI form to true. Add the following code.
Private Sub test_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim mdiClient1 As MdiClient = New System.Windows.Forms.MdiClient
mdiClient1.Dock = System.Windows.Forms.DockStyle.Fill
mdiClient1.Name = "mdiClient1"
mdiClient1.BackColor = Color.DarkCyan
Me.Controls.AddRange(New System.Windows.Forms.Control() {mdiClient1})
Me.IsMdiContainer = True
Dim frm As Form1 = New Form1
frm.MdiParent = Me
frm.Show()
End Sub
this should work for mdi form.
How to change the background color of a toolbar:
1.Place a panel on your form
2.Set the panel's docked property to Top (the default for a toolbar)
3.Set the panels backcolor to the color that you want the toolbar to be
4.Place a toolbar on the panel mentioned above
The Toolbar & its buttons inherit their backcolor from their parent control. Seems simple enough.
You could always 'subclass the toolbar and do the drawing yourself' but for a newbie to VB simple is best.

Hello everyone,I'm still migrating the VB to VB.NET Engine here.I am a beginner to VB.NET. I found this error message while I'm coding,can anyone give me a help please?
Overload resolution failed because no accessible 'New' can be called without a narrowing conversion: 'Public Sub New(selectCommandText As String, selectConnection As System.Data.SqlClient.SqlConnection)': Argument matching parameter 'selectConnection' narrows from 'System.Object' to 'System.Data.SqlClient.SqlConnection'. 'Public Sub New(selectCommandText As String, selectConnectionString As String)': Argument matching parameter 'selectConnectionString' narrows from 'System.Object' to 'String'.
And the following is my code>>
Private Sub Spam_Now()
Dim MemberDV As DataView
Dim i As Integer
Dim sql1, sql2, sql3 As String
'sql1 = "SELECT TOP 20 * FROM TT_Member WHERE Reminder = '0' AND Status = '1'"
ObAdapter1 = New SqlDataAdapter("SELECT TOP 20 * FROM TT_Mber WHERE Reminder = '0' AND Status = '1'", Obconn1) '<

You are passing a String parameter for an SQLConnection object. The argument you are passing must be an SQLConnection object and not String object.

Thanks for your solution. Do you mean that I should change that line to the following?
ObAdapter1 = New SqlDataAdapter(Obconn1, "SELECT TOP 20 * FROM TT_Member WHERE Reminder = '0' AND Status = '1'")
ds1 = New DataSet
ObAdapter1.Fill(ds1, "MemberList")
I have try but it works,so I just want to reconfirm that is what you ask me to modified?
Thank you so much for the solution and effort.

hi,
i try to send an email with attachment, but when the program fails to send out the mail, i can't delete the file (the file i wish to attach in the mail) in my local drive, i think it is locked when i am trying to send, i have used the code below to delete the file
For Each sSubstr In attach_string.Split(delim)<br />
If System.IO.File.Exists(sSubstr) = True Then<br />
Try<br />
System.IO.File.Delete(sSubstr)<br />
'MsgBox("File Deleted")<br />
Catch ex As IOException<br />
Label1.Text = ex.Message<br />
Finally<br />
End Try<br />
End If<br />
Next
i didn't catch any exception while debuging but it fails to delete the file, when i go to the path (where i the file is) to delete the file manually, windows tells me "Canot delete File: Access is Denied. Make sure the file is not ful or write protected or currently in use". Any idea how to fix that?
