I have a form with no border, how do I code it so that the end user can still drag it around the desktop?

Hi,
you need to implement your own drag/drop for this.
try the following code
<br />
'Declare vars<br />
Private CurX As Double<br />
Private CurY As Double<br />
<br />
Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseMove<br />
<br />
If e.Button = MouseButtons.Left Then 'use mouse_left_button<br />
Dim pt As Point<br />
pt.X = Me.Left + (e.X - CurX)<br />
pt.Y = Me.Top + (e.Y - CurY)<br />
Me.Location = pt<br />
Me.Refresh()<br />
End If<br />
<br />
End Sub<br />
<br />
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown<br />
CurX = e.X<br />
CurY = e.Y<br />
End Sub<br />
Above is a simple drag/drop implemented using mouse move and mouse down events

Private Sub SetPoint()<br />
If hdMousedown = True Then hdMousedown = False Else hdMousedown = True<br />
pt = Me.PointToClient(Control.MousePosition)<br />
End Sub<br />
<br />
Private Sub Form1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Form1.MouseDown<br />
SetPoint()<br />
End Sub<br />
<br />
Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Form1.MouseUp<br />
SetPoint()<br />
End Sub<br />
<br />
Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Form1.MouseMove<br />
If hdMousedown = True Then<br />
Me.Location = New Point(Control.MousePosition.X - pt.X, Control.MousePosition.Y - pt.Y)<br />
End If<br />
End Sub

You're looking for this[^] example. WHo would have thought sending data directly to an LPT port would be so complicated.

if you want dates of a month in a column just for first date of month as
dim date as new date(yyyy,mm,dd)
i.e. dim ldtFirst as new date(2007,04,01) - for april
and loop through the ldtFirst.DaysInMonth - gives total number of days in the current month, add the rows in the datagrid

Hi All,
I have a bit of a newbie question I cant seem to figure out. I am using VB 2005 Express.
I want to change the size of paper to A5 during, but the kind property is read only
If there is a log then print A4 if not print A5.
I use VBMySQLiect to get data from a MySQL database.
My Code:
<br />
Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click<br />
SQL = "select * from clients where id = '" & lvwList.SelectedItems.Item(0).Text & "'"<br />
For i = 2 To lvwList.SelectedItems.Count<br />
SQL = SQL & " or id = '" & lvwList.SelectedItems.Item(i - 1).Text & "'"<br />
Next<br />
rs = gCnn.Execute(SQL)<br />
With prnPreview<br />
.Document = prnDocument<br />
If bLog Then<br />
.Document.DefaultPageSettings.PaperSize.Kind = Printing.PaperKind.A5<br />
Else<br />
.Document.DefaultPageSettings.PaperSize.Kind = Printing.PaperKind.A4<br />
End If<br />
.ShowDialog()<br />
End With<br />
End Sub<br />
What do I need to do?
Thank you
Andrew

|
|
|

give 'None' as its border style
|
|
|
|
|
there is not border style
pls help me
|
|
|
|

He's talking about the Form's BorderStyle property. Set it to None and there won't be any method for the user to move the form from where it appears.
