Public Class MinimizeInTray<br />
Public TrayMenu As New ContextMenu<br />
Public Restorewindowstate As FormWindowState = <br />
FormWindowState.Normal<br />
Public trayicon As New NotifyIcon<br />
Public mainform As New Form<br />
Public visible As Boolean = False<br />
Sub New(ByVal form As Form, Optional ByVal icontext As String = "", <br />
Optional ByVal icon As Icon = Nothing)<br />
TrayMenu.MenuItems.Clear()<br />
mainform = form<br />
TrayMenu.MenuItems.Add("Restore", AddressOf restore)<br />
TrayMenu.MenuItems.Add("Close", AddressOf close)<br />
AddHandler trayicon.DoubleClick, AddressOf restore<br />
With trayicon<br />
.Visible = False<br />
If IsNothing(icon) Then<br />
.Icon = mainform.Icon<br />
Else<br />
.Icon = icon<br />
End If<br />
.Text = icontext<br />
.ContextMenu = TrayMenu<br />
End With<br />
End Sub<br />
Private Sub restore(ByVal sender As System.Object, ByVal e As <br />
System.EventArgs)<br />
mainform.ShowInTaskbar = True<br />
visible = True<br />
trayicon.Visible = False<br />
mainform.WindowState = Restorewindowstate<br />
End Sub<br />
Private Sub close(ByVal sender As System.Object, ByVal e As <br />
System.EventArgs)<br />
trayicon.Visible = False<br />
mainform.Close()<br />
End Sub<br />
End Class

Thanks for the code but what i want is something like outlook.
if i minimize my form then it should not be visible.
Not only minimize from tray icon but also from minimize button of the form to.

I think same code should work .
just add a button to the form which indiacates the minimize sign.
and put the code on that i same send.

write your code on form_resize event
check for form.windowstate = FormWindowState.Minimized and write your code to hide your form and show systemtray icon

workflow is the operational aspect of a work procedure: how tasks are structured, who performs them, what their relative order is, how they are synchronized, how information flows to support the tasks (wordflow) and how tasks are being tracked. As the dimension of time is considered in workflow, workflow considers "throughput" as a distinct
1.shall we develop work flow using using class library from vs.net 2.0
(vb.net)?
2.we need any dedicated language like XPDL for process defination, and link
the process and task ?
please answer to the above questions if you have.
with best Regard's

I have two dates .The difference between them is almost three months and 20 days.How should I programatically calculate the no of days in these start date and end date.Is there any inbuilt function to do it.Or I need to apply my logic to accomplish it.
currently i am using the following code
private sub abc()<br />
Dim startdate As New Date(2006, 1, 1)<br />
Dim enddate As New Date(2006, 3, 1)<br />
Dim str(1) As String<br />
Dim counter As Integer = 0<br />
While (True)<br />
str(counter) = startdate.Day & "-" & Format(startdate, "MMM") & "-" & startdate.Year<br />
counter += 1<br />
ReDim Preserve str(counter)<br />
startdate = startdate.AddDays(1)<br />
If (startdate = enddate) Then<br />
str(counter) = startdate.Day & "-" & MonthName(startdate.Month) & "-" & startdate.Year<br />
Exit While<br />
End If<br />
<br />
End While<br />
End Sub

I have this code from the net.
We can use this function to find the difference in date,month,year,time.
But it is in C#.
Please try to understand this and convert into VB.NET code.
public enum DateInterval
{
Second, Minute, Hour, Day, Week, Month, Quarter, Year
}
public static long DateDiff(DateInterval Interval, System.DateTime StartDate,
System.DateTime EndDate )
{
long lngDateDiffValue = 0;
System.TimeSpan TS = new System.TimeSpan(EndDate.Ticks - StartDate.Ticks);
switch (Interval)
{
case DateInterval.Day:
lngDateDiffValue = (long) TS.Days;
break;
case DateInterval.Hour:
lngDateDiffValue = (long)TS.TotalHours;
break;
case DateInterval.Minute:
lngDateDiffValue = (long) TS.TotalMinutes;
break;
case DateInterval.Month:
lngDateDiffValue = (long)( TS.Days / 30);
break;
case DateInterval.Quarter:
lngDateDiffValue = (long)( (TS.Days / 30) / 3 );
break;
case DateInterval.Second:
lngDateDiffValue = (long) TS.TotalSeconds;
break;
case DateInterval.Week:
lngDateDiffValue = (long)( TS.Days / 7);
break;
case DateInterval.Year:
lngDateDiffValue = (long)( TS.Days / 365);
break;
}
return (lngDateDiffValue);
}
DateDiff(DateInterval.Day,startdate,endDate)
Hope that helps.

Hi Arun
The month, quarter and year calculations in your C# code don't seem very accurate. Can't you just use the VB "DateDiff" function?

Sorry, I do not know much of VB.NET functions,
as I am using C# language.
Any way, thank you very much.

hi, is this what you want to do?
Dim startdate As New Date(2006, 1, 1)
Dim enddate As New Date(2006, 3, 1)
dim s as string
'i just pass the value of startdate & enddate to textbox
txtstartdate=startdate
txtenddate=enddate
'this will calculate the difference of your date
s=DateDiff(DateInterval.Day,strdate,enddate)
Msgbox(s)
is that what you mean dude?sorry if my instinct is wrong.

You can buy a barcode scanner, but you need to build or buy a database that turns the numbers that a bar code represents, into the details of the product that carries it.

please i need more details..
do you mean that barcode scanner automatically with application to read codes and all i nned here is tp attach this application with my database
regards

The barcode reader will only scan the code of the product.
You have to interface it with the PC.
You should have a database with columns like
Barcode,ProductName,Cost,Weight and so on.
And create an application that reads the scanned Barcode(from the barcode reader)
and fetch the corresponding properties from the database
and display them in the UI.

the only stuff you need is barcode reader. just install the barcode reader to the computer then he can read now the code in the box. thats to easy. if you scan the barcode in the box then the barcode reader will paste the code to your textbox or even in notepad.
