You're going to have to put a breakpoint on the FileOpen statement in the btnFind_Click event, then step through the code line by line and watch what's happening in each of the variables in your Do/While loop. It looks like you never find the data your trying to search for.

Dear All,
Is it possible to write a string from vbscript to console. How can we write that?

You might be able to use Wscript.Echo("A String")
|
|
|
|
|
So long as you run your script with the CSCRIPT exe instead of the default WSCRIPT version, all you need is WScript.Echo "message...".

I am writing a RFID driver and I face a problem in writting "set baseband filter"
Here is the problem
Filter mask:
H G D B C E
1/0 1/0 1/0 1/0 1/0 1/0
I want to use Window application form in visual basic language to do this. If the Filter H,B,C of the filter turn on, Filter mask byte should set to &H4C. If all the filter turn on, The mask byte will be &H3F.
So how to write this??
If H,B,C of the filter on,shall I get the string "1 0 0 1 1 0"
and convert it into binary , and then to hexidecimal?? If yes, how to convert it?
If no, any easy way to do this programme??
Thank you for your suggestion.

It isn't advisable to use VB.NET or any other .NET language to write a driver.

It doesn't matter what you used to pick the dates. The dates will be in a DateTime object. You can compare them in the normal way
a = b
a < b
a > b
a <= b
a >= b

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

<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.

Magi

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
