In the code for your LinkButton type: Process.Start("http://www.example.com"). This will open a new tab/window in your default browser.

I have looked for ever for this information. Does anyone know of a good tutorial or description of how to receive information from the sound card, c#,VB.net or VBA preferably. I am a ham radio operator and would like to write my own Morse Code decoder via sound card interface. There are many out there but I want to integrate this into a radio control program

You put this in a Dispose implementation?? What are you trying to do with this code? This is something you would normally find in a form's Closing event, not Dispose.

Hi:
Supouse I have this Table in a Access database:
Table Name: CostumersType
Fields: ID(Autonumber),Name(text(50)), Costumers(object)
And this Class
Class Name: Costumers
Class Properties: name(string),id(integer)
And i add some items of the class costumers to an arraylist called Costumers.
Then I want to save the content of the arraylist to the field costumer of the database. And I don't know how.

This is not a possible i think and not a good approach either.
Why you need to put arraylist in the table field?

Hi,
I developed an windows application that inserts some values into database.It is working fine.But now i have two problems
1) I prepared an exe file for my application and installed in another system. When i executed my application in that system it given me error as it doesn't find database. I have given the Datasource as "Data Source=D:\Dotnet\SurveyApp\SurveyApp\SurveyData.mdb".
Can any one suggest me what i have to do to solve this
2)I have another doubt i.e is it necessary that ms access should be installed the syystem where i installed my application?

And is that the location of the database on the new machine? If not then it seems fairly obvious to me that you need to change the location of the database in the datasource. If this value is hard coded then you might want to learn the lesson not to hard code file paths in an application.
So, where is the database now?
vijay2583 wrote: I have another doubt i.e is it necessary that ms access should be installed the syystem where i installed my application?
That depends. Do you intend to share the data? If yes, then SQL Server is probably a better option as it is more able to share data between multiple machines. If not, then you probably want to copy the database.

Dim Temp As Ink<br />
FileNumber = FreeFile()<br />
FileOpen(FileNumber, "c:\inklist.txt", OpenMode.Random, OpenAccess.Read, , Len(Temp))<br />
FindLastRecordNo = 1<br />
Do While Not EOF(FileNumber)<br />
FileGet(FileNumber, Temp, )<br />
FindLastRecordNo = FindLastRecordNo + 1<br />
Loop<br />
FileClose(FileNumber)<br />
End Function<br />
<br />
I have no problem with this event <br />
<br />

Dim MyInk As Ink, Count As Integer, Temp As String<br />
Dim MyLine, MySubString As String, LineWidth As Integer = 60<br />
FileNumber = FreeFile()<br />
FileOpen(FileNumber, "c:\inklist.txt", OpenMode.Random, , , Len(MyInk))<br />
Count = 1<br />
lstInk.Items.Clear()<br />
Do While Not EOF(FileNumber)<br />
FileGet(FileNumber, MyInk, Count)<br />
Temp = MyInk.InkID + MyInk.InkName + MyInk.Weight<br />

Exit Do<br />
End If<br />
Loop<br />
FileClose(FileNumber)<br />
End Sub

wating for your kind help

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?
regds
Shihab

|

|

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
