In MsgBox, how do SystemModal and TopMost differ?

3 posts in this topic

I'm probably just being dense but when I run both of these scripts (compiled) I don't detect any difference in the user experience. (am running Windows 8.1 64b)

SystemModal

#include <GUIConstantsEx.au3>
 #include <MsgBoxConstants.au3>

 $hGUI = GUICreate("Test", 500, 500)
 GUISetState()

 MsgBox($MB_SYSTEMMODAL, "SystemModal", "Press me to continue")

 While 1
     Switch GUIGetMsg()
         Case $GUI_EVENT_CLOSE
             Exit
     EndSwitch
 WEnd

 

TopMost

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

 $hGUI = GUICreate("Test", 500, 500)
 GUISetState()

 MsgBox($MB_TOPMOST, "TopMost", "Press me to continue")

 While 1
     Switch GUIGetMsg()
         Case $GUI_EVENT_CLOSE
             Exit
     EndSwitch
 WEnd

There is not an icon on the top left of the window using the $MB_TOPMOST. 

$MB_SYSTEMMODAL 4096    System modal (dialog has an icon)

$MB_TOPMOST 262144  MsgBox() has top-most attribute set

Thank you, MikahS, you are correct sir!  I had not noticed the icon. 

I thought SystemModal had more to do with "blocking", but it doesn't seem to block any more than TopMost. Maybe the icon is the only diff.

      Hello,
      it's quite often, that someone asks how to change the texts of the MsgBox buttons or the InputBox buttons or how to change the position of ta MsgBox. Since years I use CBT hooks for that, but now I made a small UDF out of it for the ease of use. Of course you can build your own GUI or use already existing UDFs to do the same, but I like this way and you can hack (hook) the inbuild InputBox.
       
      HookDlgBox.au3

      Hi Gang
      Is there a definition of what exactly 
      $MB_SYSTEMMODAL means and when it should (and not) be used?
      Like in 
      #include <MsgBoxConstants.au3> MsgBox($MB_SYSTEMMODAL, "Title", "This message box will timeout after 10 seconds or select the OK button.", 10) Thanks
