Displaying Tooltips for all users logged on


Go to solution Solved by FatherTed,

Recommended Posts

Hi,

Bit of a newbie question here.

I have an application than monitors USB activity. The application works fine, detects USB key insertion and displays tooltip messages.

The issue I have is that I will be using this application on multiple machines, and running it with elevated privilages. When I do this, the application is working fine, everything happens exactly how it should but I do not get any Tooltips showing.

I am assuming that this is because the application is not running as the currently logged on user.

Is there a way to get tooltips to display no matter which user is logged on??

Thanks

FatherTed,

Welcome to the AutoIt forum. :)

First lesson - always post the code with which you are having difficulty (or a small reproducer). It greatly increases the chances of you getting sensible help quickly. ;)

Hi,

Here's a small snipit of my code.

For $Key In $oSourceFiles

If Not $oDestinationFiles.Exists($Key) Then

AutoItWinSetTitle($_SingleTonKeyTrayTip) ; set the TrayTip AutoIt Window Title

AutoItSetOption("TrayIconHide", 0) ;0=show, 1=hide tray icon

TrayTip("MEDIAKEY Update","Transfering " & $Key,10,1)

;GUICtrlSetData ($Detail,"Transfering " & $Key )

$SyncRet = FileCopy($sSource & "\" & $Key, $sDestination & "\" & $Key, 9)

If $SyncRet = 0 Then $SyncSuccess = False

Else

The tooltip displays fine if i run it as the logged on user, I want to run it from a scheduled task as a system process and show the tooltip no matter who is logged on.

Thanks

The only way I know of to run as System and interact with the desktop of whomever is logged in would be to run the application as a Service. You might check out SrvAny, though I believe it is buggy in Win7. There was also a thread in the Examples section regarding running your script as a service, I'll see if I can dig up the link.

Can you get it to show MsgBox alerts?  Not pretty, but it would at least be something.

My second idea is vague and a bit of a stretch.  Is there any way to hook it into the Windows COM+ system and use that to send user alerts?  I don't know if you can make a tooltip that way, however.  I have very little knowledge of COM stuff, but it should be possible.

My third idea is to create a separate application/script that is in a location accessible to all users.  You then use your system script to call the accessible script which in turn creates the tooltip.

FatherTed,

I looked into WTSSendMessage a bit on MSDN.  I'm sure you're aware it's a Remote Desktop function.  I have only a little experience with C and with AutoIt's DllCall(), and I put together what I could.  The base functions are "there", but it doesn't work yet.  I've taken it as far as I can.  I'm posting this for you or anyone else to look at and hopefully make some progress with.

Best of luck!

EDIT:

For those who just want to peak, here's the code

I just learned something cool.  If you're on Windows 7, you can use the command line program "msg" to send a message.  Just run "msg" from a Win7 console and it'll show you how to use it.  It would be quite simple to call it from AutoIt.

If that doesn't work, then I agree with Melba - post (a working sample of) your code and we'll see what we can do from there.

o/ Success ......
 
Thanks for your help guys, I did a bit more searching and found some Autoit code on the forums.
 
After a little bit of editing I have a working solution.
 
here's the final code
 
Func _TSSendConsoleMessage($TitleText, $MessageText, $ButtonSet = 0, $Timeout = 10, $Wait = False)
    $pTitle = DllStructCreate("char Title[32]")
    $pMessage = DllStructCreate("char Message[128]")
    $pResponse = DllStructCreate("DWORD Response")
    $SessionId = WTSGetActiveConsoleSessionId()
    DllStructSetData($pTitle, "Title", $TitleText)
    DllStructSetData($pMessage, "Message", $MessageText)
    $wtsapiCall = DllOpen("Wtsapi32.dll")
    $SendMessageResult = DllCall($wtsapiCall,"BOOL","WTSSendMessage","HANDLE","WTS_CURRENT_SERVER_HANDLE","DWORD",$SessionId,"str",DllStructGetData($pTitle, "Title"),"DWORD",DllStructGetSize($pTitle),"str",DllStructGetData($pMessage, "Message"),"DWORD",DllStructGetSize($pMessage),"DWORD",$ButtonSet,"DWORD",$Timeout,"DWORD",DllStructGetPtr($pResponse),"BOOL",$Wait)
    DllClose($wtsapiCall)
EndFunc

Func WTSGetActiveConsoleSessionId()
    $Ret = DllCall('Kernel32.dll', 'dword', 'WTSGetActiveConsoleSessionId')
    Return $Ret[0]
EndFunc

To test i call it like this

_TSSendConsoleMessage("TITLE","MESSAGE","0","10","FALSE")

 

Thanks again guys.
