sandyd 0 Posted August 17, 2006 Hi all, I'm looking for a way to trap an erro in the following code: $WshNetwork = ObjCreate("WScript.Network") $PrinterPath = $Server & GUICtrlRead($cmbPrinters) ; Add network printer $WshNetwork.AddWindowsPrinterConnection($PrinterPath) If the $cmbPrinters does not contain a valid printer, I need an error message to say so. Any ideas? ----[ SandyD ]--- Share this post Link to post Share on other sites
MHz 80 Posted August 17, 2006 (edited) Perhaps this untested use of WMI may validate the printers name? Func _PrinterNameCheck($sPrinterName, $strComputer = ".") ; Function: Resolve Printer name Local $objPrinter Local $objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $strComputer & "\root\cimv2") Local $colInstalledPrinters = $objWMIService.ExecQuery ("Select * from Win32_Printer") ; Loop through collection For $objPrinter in $colInstalledPrinters If $sPrinterName = $objPrinter.Name Then Return True EndIf Next EndFunc Edit: Localized variables Edited August 17, 2006 by MHz Share this post Link to post Share on other sites
DaleHohm 65 Posted August 17, 2006 Also, see the example in ObjEvent for implementing a COM error handler. There is also a discussion of it in the general Obj/Com section of the helpfile.
