dufran3 Posted July 10, 2007 Share Posted July 10, 2007 (edited) Super simple UDF, I'm sure someone has created something similar, and better I'm sure. But this worked for me, just wanted to share it with everyone. All it does is check to see if an application is installed by searching the registry for the "application name" as it appears in Add/remove programs. ;=============================================================================== ; ; Function Name: _IsInstalled() ; Description: Checks to see if application is installed ; Parameter(s): $s_String - Required: Application name to search for, !!Must be exactly as it appears in Add/Remove Programs ; Requirement(s): AutoIt3 V3.2 or higher ; Return Value(s): On Success - Sets global "$IsInstalled" varibale to 1 ; On Failure - Sets global "$IsInstalled" varibale to 0 ; Author(s): *** ;=============================================================================== Func _IsInstalled($s_String) $searchpath = 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' $valuename = 'DisplayName' $IsInstalled = 0 For $i= 1 to 10000 $currentkey = RegEnumKey($searchpath, $i) If @error <> 0 then ExitLoop $displayname = RegRead($searchpath & "\" & $currentkey, $valuename) If $displayname == $s_String Then GLOBAL $IsInstalled = 1 Else EndIf Next EndFunc Edited August 16, 2010 by dufran3 Link to comment Share on other sites More sharing options...
WeMartiansAreFriendly Posted July 11, 2007 Share Posted July 11, 2007 well, nice job. heres a more standard UDF (User Defined Function) layout if your interested ;example Local $program = 'AutoIt v3.2.2' Local $IsInstalled = _IsInstalled($program) Msgbox(0, $program & ' is installed', $IsInstalled=1) ;=============================================================================== ; ; Function Name: _IsInstalled() ; Description: Checks to see if application is installed ; Parameter(s): $s_String - Required: Application name to search for, !!Must be exactly as it appears in Add/Remove Programs ; Requirement(s): AutoIt3 V3.2 or higher ; Return Value(s): On Success - Sets global "$IsInstalled" varibale to 1 ; On Failure - Sets global "$IsInstalled" varibale to 0 ; Author(s): Kevin Sanders ;=============================================================================== Func _IsInstalled($s_String) Local $searchpath = 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' Local $valuename = 'DisplayName' For $i = 1 to 10000 $currentkey = RegEnumKey($searchpath, $i) If @error then ExitLoop $displayname = RegRead($searchpath & "\" & $currentkey, $valuename) If $displayname == $s_String Then Return 1 EndIf Next Return 0 EndFunc Don't bother, It's inside your monitor!------GUISetOnEvent should behave more like HotKeySet() Link to comment Share on other sites More sharing options...

dufran3 Posted July 11, 2007 Author Share Posted July 11, 2007 (edited) The reason I don't use Return, is because I'm not sure how to read from it. I know that if I set the GLOBAl variable $IsInstalled =1, then I know I can say, If $IsInstalled == 1 Then "Do This". I"m not sure how to evaluate what the function returned... Edit: Nevermind, now I see from your example....Local $IsInstalled = _IsInstalled($program) Edited July 11, 2007 by dufran3 Link to comment Share on other sites More sharing options...
