RunOnce

Recommended Posts

I only have this in the msgbox.exe

MsgBox(0,"1","Test")

I have added a key to the RunOnce registry and it works.

RegWrite("HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce", "SCCM", "REG_SZ", "%logonserver%\netlogon\msgbox.Exe")

But when I reboot and I login to the computer I expect a msgbox to apear, but it does not.

Why can that be?


Yours sincerely

Kenneth.

Did you compile the executable to require admin credentials?

Programs in RunOnce are run before the user has logged in.  I wrote a small script to delete every instance of index.dat on my C: drive.  I set it to RunOnce.  It could delete all the index.dat files because the user had not logged in yet(even if there is no explict login screen because the user login is automatic with no password.)  What happened in my case is I could see the system wait for all the files to be deleted before I got the desktop.

I guess it is similar to running a program as a service in that there should be no user interface.  RunOnce is most used by installers that clean up no longer needed files during the reboot after an install.

#include <MsgBoxConstants.au3>

#RequireAdmin

If IsAdmin() Then MsgBox($MB_SYSTEMMODAL, "", "The script is running with admin rights.")

I tried this, but I get no messagebox.

How is it possible for me to continue a installation after a reboot?

I just learned this by searching now.  There is a program in system32 called runonce.exe.  Evidently it is a wrapper for the RunOnce key that kludges around the login issue.  You might ask on Inno Setup forum as that install maker is pretty open and the author may be willing to discus the nuances of the install spanning booting.

      Hi,
      I have a situation where I need to make one request to get a kind of pre-logon page, then click a link on that pre-logon page, which then returns a login form page, and then fill in information in the form page and submit it.
      How can I handle that using AutoIT?
      I can get the AutoIT script to tab to the link, then send an ENTER, which then causes the FORM page to appear in IE.  However, I cannot seem to get the form object from the FORM page (_IEFormGetObjByName fails when it searches for the form).  Why is that, and how can I get the AutoIT to process the FORM page?
      Thanks,
      Jim

      Hello friends, I have a simple question, can I have a variable that is not reset, even if my program is closed?
      That is, I want to make a program that can only be opened once, have a variable $ ini = 0, when it is opened for the first and only time it becomes $ ini = 1, so that it can not use the program a second time, as if it was a test software.
      I do not want the variable to depend on a reading of an external file that is easily manipulated. Thank you.

      My program has to first search for names in Column D that do not match up with column C. I got that search to work using arrays. It was slow and I could not figure out how to delete them so I just manually put coded the names that do not belong. I found their cell location but I do not know how to store that location and delete it.
      This is what I have so far.
      Local $NameToDelete1[6]  = _Excel_RangeFind($OpenWorkbook, "Smith, Bill") _ArrayDisplay($NameToDelete1, "Excel UDF: _Excel_RangeFind Example 1", "", 0, "|", "Sheet|Name|Cell|Value|Formula|Comment") _Excel_RangeDelete($OpenWorkbook.ActiveSheet, $NameToDelete1[2], $xlShiftUp)  
      Please help, I wanted to have this program done yesterday but I did not see this problem until yesterday.

      So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how  to write it in multiple lines
      Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work

      #include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
      The first one doesn't use the comma as a delimiter. (so I get a single column array)  I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters. 

      I looked again at the documentation:
       
      #include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
      And I with or without the flags params I should be getting a 2D array due to my file being a csv. 
      I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.
