Yes, Once a desktop is created it cannot be destroyed, but a simple Random in the name of the desktop, can make it unique.
And I said, that this is I guess, just a best match to what SVB needed...

Quick and dirty way of reversing a string, any ideas?

Yep - an easy way - use the StrReverse() function.

This is rom the Visual Studio 2005 help files...

Dim myString As String = "ABCDEFG"<br />
Dim revString As String<br />
' Returns "GFEDCBA"<br />
revString = StrReverse(myString)<br />

Progress bar

I want to place a Progress Bar on my form, but I don't know how long particular tasks will take.
I tried using a Timer Control, but that didn't work.
The only thing I'm doing is changing the Cursor to WaitCursor and back to the default.
Any ideas greatly appreciated.

Thank you.

Hmmm... difficult when you don't know the length of a piece of string!

Three possible approaches...

1. use a ProgressBar but dynamically change the increment value until you KNOW how much longer it will take, then intelligently divide the remaining bar length into equal intervals, or

2. use the "pseudo-ProgressBar" approach which increments up to (say) 90% and then waits until the process is finished and only then sets the bar to 100%, (this was used in the past by some disreputable installation programs), - not really recommended Smile | :)

, or

3. use an animated GIF or cursor to indicate to the user that things are happening and not to be tempted to CtlAltDel!

The most important thing is to convey to the user that progress is being made and not to interrupt the program.

Continuing Steve's words:
4-You may use other progressbars which only state that your program is working (like windows XP startup) which does not show a fixed point at any time, and just passes across and then starts from the beginning...

Do you have any example code?
I tried to Thread this process out but to no avail.

Here's is what I'm trying to do:
I want to display the progress bar when I load in data on my Form1_Load Event.
Currently, I'm displaying a progress bar, it progresses from 1 = 120000,
then I do the .Fill Method to load the data onto a form.
The progress bar has completed, but the data is still loading.
The cursor is still the wait cursor.
( I know this is not correct)

Receiving Net Send within application textbox

4-Apr-06 1:23

No, unfortunately I don't have any source code for the use of that pseudo-progressbar...
But I try to give you some idea on which might be helpful...

You can make a form, which displays Processing (and maybe a gif animation stating that the program
is doing something) and the hourglass icon. Then in your main form create a thread which shows the processingform
as a dialog (using ShowDialog method.)
Then in the Load function write:

myThread.Start
oleDataAdapter1.Fill(DataSet1)
myThread.Stop

I think this would be better than a progressbar in you main form.

I need help to make an application which can both send and receive netsends from LAN. It will be like winmessenger. I did the sending part already, thanks to the site, don't have any clue about how to proceed for receiving netsends in my application textbox.

the thread is still open.
the site shows code only for sending, it receives a copy of sent messages.
But it doesen't actually receive messages.
When somebody net sends me ishould get the net send within my application.

I haven't used it recently, but a few years ago I played with it in a small network environment. It intercepted Net Send messages just fine.

Have you actually tried it? Maybe the code has been changed...??? I think I have the old version in some backup files somewhere.

yes i have tried the code, it is not receiving net send within the application, just normal windows popups are coming.
Can you please send me those files if you have them.

I tried the old code...no luck.

I was on Win2000 at the time. No idea why it isn't working now...I'm on XP. Shouldn't matter though.

If you feel up to it, check out the sb_StartHook procedure, and the WndProc function. You will see code written that is intended to intercept the messages from the Messenger Service (and it worked fine for me a few years ago):

Private Sub sb_StartHook()<br />
'************************************************************************<br />
'The following code will start the hooking.<br />
'************************************************************************<br />
    'Used for Hooking START<br />
    uRegMsg = RegisterWindowMessage(ByVal "SHELLHOOK")<br />
    Call RegisterShellHook(hwnd, RSH_REGISTER) ' Or RSH_REGISTER_TASKMAN Or RSH_REGISTER_PROGMAN)<br />
    OldProc = GetWindowLong(hwnd, GWL_WNDPROC)<br />
    SetWindowLong hwnd, GWL_WNDPROC, AddressOf WndProc<br />
End Sub

In WndProc you'll find:

<br />
If wMsg = uRegMsg Then<br />
Select Case wParam<br />
Case HSHELL_WINDOWCREATED<br />
If GetWndText(lParam) = "Messenger Service " Then<br />
                    <br />
  ShowWindow lParam, SW_HIDE<br />
                    <br />
  'Get Window Text.<br />
  strData = String(1000, vbNullChar)<br />
                        <br />
  'Get Child Window handle with type Static (Label).<br />
  hWndChild = FindWindowEx(lParam, 0&, "Static", vbNullString)<br />
                    <br />
  'Get the text of the Child Window (Label).<br />
  retHwnd = GetWindowText(hWndChild, strData, intDataLength)<br />
                    <br />
  'Destroy the wondow.<br />
  'PostMessage lParam, WM_KEYDOWN, VK_RETURN, &H1&<br />
  PostMessage lParam, WM_CLOSE, 0&, &H1&<br />
<br />
  ...etc...

Sorry it didn't work out. Maybe you can modify this code to work. I just don't have time right now.

Encryption & Drag/Drop

Hello, I'm not new to programming. However, I am new to dragging/dropping and encryption. I am wanting to create a password manager for myself as I am getting tired of trying to remember all of my passwords. I think this would be a good oppurtunity to gain more knowledge. Any tutorials on encryption and drag/drop?

Thanks
