I want to make an application that when I'm with the mouse on it ... it sets the opacity to 100 ... and when the mouse is .. outside the form.. it sets the opacity to 50
THE PROBLEM IS that the code...is working when the mouse is over the content of the form... it does not include the border of the form or the form controlbox(min,max,close) ... don't know why 
I've managed to make something like that with a timer set to 100 and with this piece of code:
If Cursor.Position.X >= Me.Left And Cursor.Position.X <= Me.Right Then
If Cursor.Position.Y >= Me.Top And Cursor.Position.Y <= Me.Bottom Then
mouseover = True
Else
mouseover = False
End If
Else
mouseover = False
End If
Please help with an idea .. Thanks

That's because those events only fire inside the client area of the form. What you area referring to is the non-client area, borders and titlebar. There are no events for those areas.
You'd have to override the forms WndProc and capture the window messages, like WM_NCHITTEST, directly to to see if the mouse is over those areas. If so, you just fire your own custom events if you want, or make calls directly to some method, depending on what you need to do.

Thank you very much for your answer! I've done it  and also I've just learned something new
The code for doing that is:
Protected Overrides Sub WndProc(ByRef m As Message)
MyBase.WndProc(m)
Dim WM_NCHITTEST = &H84
If m.Msg = WM_NCHITTEST Then
MsgBox("mouse is over")
End If
End Sub
Thanks!

I am reading from a text file and inserting a line "REF*LU*" at various stages in my text file. The ending textfile is in UNIcode/Little Endian; how do i convert this to ASCII? See my code below
Dim newString As New StringBuilder<br />
newString.Append(My.Computer.FileSystem.ReadAllText(FileName))<br />
newString.Replace(oldISAGS, newISAGS)<br />
newString.Replace(myString, myString & vbNewLine & "REF*LU*" & refNum & "~")<br />
newString.Replace(myString2, myString2 & vbNewLine & "REF*LU*" & refNum & "~")<br />
My.Computer.FileSystem.WriteAllText(FileName, newString.ToString, False)
Thanks.

1.
My.Computer.FileSystem.WriteAllText, without an explicit Encoding, creates a UTF-8, not a Unicode, file; the documentation says:
"When no encoding is specified, UTF-8 is used. The byte order mark (BOM) for the encoding is written to the file unless you specify Encoding.Default, which uses the system's current ANSI code page..."
If you don't want a BOM, use Encoding.Default; or use File.WriteAllText which works without BOM by default.
2.
why do you use a StringBuilder here? I don't think it will be faster than similar string operations in this app, as all you do are global operations, not a long sequence of appends.

Luc,
Thanks for your comments.
I used StringBuilder at the time on the fly when this was a simplier applet; it still works well for the intended use. But I agreed that one day I should clean it up and use more global codes instead of a series of appends.
Can you give me a sample of where in the code and how I should use the encoding.ASCII?

I could, but I'm not going to.
I explained two ways to solve your problem, now use the documentation to figure out the details. Don't be lazy, and learn.

Thanks anyway Luc. no laziness here; just a little green and under pressure to get it done ASAP. I will do my homework. Regards.

Just to close the loop on this. I got my solution with the codes below. Luc, I did my homework over the weekend. Thanks for the pointer.
<br />
'ASCII encoding<br />
Dim bteCode() As Byte<br />
bteCode = Encoding.ASCII.GetBytes(Me.lblClaimsFile.Text)<br />
<br />
My.Computer.FileSystem.WriteAllText(FileName, newString.ToString, False, Encoding.ASCII)<br />
<br />
MessageBox.Show("End of Translation ... Adios!")<br />
IT.

Hi to all
I have find out this problem.
using outlook namespaceclass object you can use pickfolder method. using this it will open dialog box and allow you to create new folder and also choose already created folder.
for example:
dim outlookNameSpace as outlook.namespace
myFolder = outlookNameSpace.PickFolder
Regards

Hi, I'm looking to create a database within my program. I was planning on using a record type, following something my teacher has said about it being similar to an array. However, having looked for this record type, I figure it must have been for an older version of visal basic.
Is there a way that I can create a database, similar to an array? I'd like to keep it within visual basic if possible, rather than using access, as seems to be quite common.

An array is not a database.
The only thing you can do that somewhat is similar to a database is use a datatable / dataset
But anything you store in there is just in memory and will be lost on exiting the program.
outhwaik wrote: using access, as seems to be quite common
Not really, sql-express is common.
What are you trying to do here?

I'm planning on saving the data in a text file, to be loaded on starting the program, so the data wouldn't be lost.
I want to avoid using access if possible, as the machine this program will eventually be used on doesn't have access.
What I'm acutally trying to do is, or at least i thought, quite simple. It'll effectively be a small database of the members of a Brownie pack, with names, address, phone number etc stored in different fields.
