InputBox always on top

Recommended Posts

pixelsearch

Hi everybody,
I wanted to share with you this short piece of code where InputBox will always be on top (it's important to have it on top, kind of "MsgBox style") .  It's the shortest way I found to make it happen, with few lines of code :

Do
   $sNb_Quest = InputBox("Quiz", "How many questions to answer ? (1-99)", "10", " M2", _
      220, 140, Default, Default, 0, GUICreate("", 0, 0, 0, 0, Default, @SW_SHOWDEFAULT))
   If @error = 1 Then
      MsgBox(4096, "End of script", "You choosed to Quit")
      Exit
   EndIf
   GUIDelete() ; place this line here, not just after InputBox, or @error will be reset to 0
   $iNb_Quest = Number($sNb_Quest)
Until $iNb_Quest > 0 And IsInt($iNb_Quest) = 1

MsgBox(4096, "Result", "Your choice : " & $iNb_Quest)

In the precedent code, the user can't type more than 2 characters. Inputs like "0" or ".5" or "-1" will be automatically rejected, also the Input is mandatory, default is 10. The last parameter, GUICreate, is the key to have this InputBox always on top (in a quick way)


My question is : should GUIDelete() be present in the code or can we delete that line ?
It seems to work fine without the GUIDelete() line, but in case the loop repeats several times (because of bad inputs), then we will have several GUICreate() without a single GUIDelete() ?
Thanks for... your input :)

this snipet:

$hGui = GUICreate("", 0, 0, 0, 0, Default, @SW_SHOWDEFAULT)
Do
    $sNb_Quest = InputBox("Quiz", "How many questions to answer ? (1-99)", "10", " M2", _
            220, 140, Default, Default, 0, $hGui)
    If @error = 1 Then
        MsgBox(4096, "End of script", "You choosed to Quit")
        Exit
    EndIf
    $iNb_Quest = Number($sNb_Quest)
Until $iNb_Quest > 0 And IsInt($iNb_Quest) = 1

MsgBox(4096, "Result", "Your choice : " & $iNb_Quest)

do the same.

Like you already speculated, I would agree that the cleanup is probably a good idea in order to avoid any leaks.

Agreed, just uses the same parent gui for each InputBox.  Probably less critical to clean up versus creating a new one each loop.

Great ! So I'll create the "dummy GUI" outside the loop, as AutoBert suggested.

Then I'll delete it outside the loop too, which should lead us to this final snipet :

$hGui = GUICreate("", 0, 0, 0, 0, Default, @SW_SHOWDEFAULT)
Do
   $sNb_Quest = InputBox("Quiz", "How many questions to answer ? (1-99)", "10", " M2", _
      220, 140, Default, Default, 0, $hGui)
   If @error = 1 Then
      MsgBox(4096, "End of script", "You choosed to Quit")
      Exit
   EndIf
   $iNb_Quest = Number($sNb_Quest)
Until $iNb_Quest > 0 And IsInt($iNb_Quest) = 1

MsgBox(4096, "Result", "Your choice : " & $iNb_Quest)
GUIDelete($hGui)

 Thanks to both of you !

By the way, I guess everybody would like his own InputBox(es) to stay on top. Don't you think the help file could be amended with this kind of snipet, as the InputBox help file doesn't indicate at all how to create an "on top" InputBox ?

      Hi, 
      Is there any possibility to change the cancel button text to quit in the Inputbox?
    • dmkirkland

      I'm wondering if, once again, I might be able to get some assistance from those of you who are much more knowledgeable than I. I have written a function that uses an InputBox and asks for the name of the adapter the user wants to manipulate. The script is designed to assign the name of the adapter to the entire program (a global variable) for use in other functions throughout its use. It can also be called again to change the adapter or, if it mistakenly didn't get set, set it. The issue I'm having is that I can't figure out a way to keep the function from "clearing" or "deleting" the variable if the cancel button is pressed. The idea is that if the user assigns the variable at the start of the program running (the function is called before anything else happens in the script) then, mistakenly/accidentally, runs the function again and, at the InputBox, the user clicks "Cancel" it will leave the variable alone. Currently, I've been able to (after much trial, tribulation, and troubleshooting) get it actually cancel the operation when "Cancel" is pressed or assign the variable as needed/preferred when the information is entered and "OK" is pressed. However, if "Cancel" is pressed (again, after the variable has already been assigned), it completely clears the variable's assignment (as evidenced by calling the variable in another function. Below is the code for the function. Please let me know if more functions are needed for diagnosis.
      Func selectAdapter()
          Global $adapterName
          $adapterName = InputBox("Select Adapter", "Please input the adapter name" & @CRLF & @CRLF & "or leave it at the default:", "Ethernet")
          If @error = 1 Then
              Return
          EndIf
      EndFunc

      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.

      Hello,
       
      I know you can set flags, e.g. 1, 2, 3 to change the buttons in a MsgBox from "OK" + "Cancel" to "Yes" + "No" + "Cancel", etc...
      However...
      1- Is it possible to manually say what the buttons say? E.g. "Pass" + "Fail"?
      2- Is it possible to do that with an InputBox rather than a MsgBox?
      3- What in your opinion would be better design for the user? A ) Pressing "Fail" on a MsgBox creates a "InputBox" with only a textbox and "Submit" button? B ) Only being able to press "Fail" on an InputBox if the textbox is not empty?
       
      Thank you in advance.
