hi all:
how the bold code suppose to check if the fsi(FileSystemInfo object)
contain file or directory ??
its working fine but i want to understand how ??
Sub DisplayFileSystemInfoAttributes(ByVal fsi As IO.FileSystemInfo)
' Assume that this entry is a file.
Dim entryType As String = "File"
' Determine if this entry is really a directory.
If (fsi.Attributes And FileAttributes.Directory) <> 0 Then
entryType = "Directory"
End If
End Sub

The And operator ( && in real programming languages ) returns true if the value on the right is also contained in the value on the left. In other words, if Directory is 0010 in binary, then 0011 and 0010 will both return true, 0001 will not.

If Directory is a number ( and, as an enum, it is ), and it's binary representation is 0010, then the collection of values represented by 0010 and 0011 will both contain the Directory value, and will so both return true when Anded with Directory.

ok... but why the coder choose to add the value of the file attributes
to FileAttribute.Directory(10000)
example of directory
10110 and
10000
------
10000
example of file
100000 and
010000
------
000000
why is both cases we have to add the value(10000)

You're not adding, you're comparing. The AND operator returns true if a flag is present on both sides.

Then start Googling to do your own research on what's involved since you appear to know nothing about what you're getting into.
Also, VB6 is probably not the best language to choose for this. Visual C++ would be much better since you'll need the performance benefits.

Hello,
I have the code below in a combo boxes keyup event. I want to do something then the user presses the tab key. But it does not work. I have tried this with other key i.e. enter, shift, letter, and numbers. But does not work when the user presses the tab key.
Does anyone know why this is.
<br />
If e.KeyCode = Keys.Tab Then<br />
'Do something then the user press the tab key<br />
End If<br />
Thanks,
Steve

The tab key moves focus to the next control. If you want it to do something else, I'd guess you need to catch KeyDown, not KeyUp.

 I am stuck on a project. I have a .txt file with 8 separate lists in it. Each list is separated by a "#" sign. I need to use StreamReader to read each individual list from the file and transfer each list into a separate combo box for user selection. I can read the file but I am having trouble passing each line of a list into the combo box. Basically I only get the last line.
My Code is as follows:
Dim SongStreamReader As IO.StreamReader
Dim Record As String
If IO.File.Exists("Country.txt") Then
SongStreamReader = IO.File.OpenText("Country.txt")
Do Until SongStreamReader.Peek() = -1
Record = SongStreamReader.ReadLine()
Me.uiList1Combo.Text = Record
Loop
SongStreamReader.Close()
Else
MessageBox.Show("File Does not exist", "Country", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
End Sub
Any Suggestions?

Hey all,
I was wondering if I'm even looking in the right direction on this one.
What I want to have happen, is in the client's PC, call CreateObject('ObjectOnServer.MyClass') then begin using the methods I built into the class on the server. Something like... getXML('identifiy where the xml is') and that will pass me back the XML.
Can the CreateObject access a class on the web? If so, any pointers on how would be appreciated.
Thanks,
Mike

This will only work if the component you want to call is registered on the clients machine as a remote-call object. You cannot specify the path to the object in the ProgID string you pass to CreateObject. Your object registration file must include this information. You'll use RegSvr32 to register the component using this file, just like any other. The registration file you use depends on the component you're registering.

Your best bet when starting out is to buy a book, not to read stuff online, which can be disjointed.
I'd sure love it if you removed that spam from your sig.

Hi, using VB net(2003) in a Windows Application, my question, How upon a button click allow calculation to be done if certain character are present in textbox like A to E, a to e, a dot, and finally the word cost. All other character must produce an error message. I try with ARRAY it does not seem to work. Could someone show me the way or a little tutorial would be greatly appreciate.
Thank you in advance.

A regex seems the best way to go. Better yet would be to only allow valid characters to be entered. The textbox has a KeyChar event, in this event, the eventargs include a boolean flag called Handled. If you set this to true, the keypress will be ignored.

I got 2 quick questions:
1> System.Diagnostics.Process.Start("Explorer.exe", "%USERPROFILE%\My Documents\") returns folder doesn't exist because I have my documents in there, but I need to goto my documents, what should I do?
2> How do you set a global variable in .net that is accessable across multiple forms. Like Dim blah as Global?
Thanks...
