Hide/Delete a dropdown
  I am using NSDialogs and I can create a dropdown on the fly, but is there a way to destroy a dropdown on the fly..

For Ex.

 ; === Locations (type: DropList) ===

  ${NSD_CreateDropList} 89 85 159 21 ""

  Pop $hCtl_RenameMe_Locations

  CreateFont $hCtl_RenameMe_Locations_Font "Microsoft Sans Serif" "8.25" "400"

 SendMessage $hCtl_RenameMe_Locations ${WM_SETFONT} $hCtl_RenameMe_Locations_Font 0

  SetCtlColors $hCtl_RenameMe_Locations 0x000000 0xFFFFFF

 ${NSD_OnChange} $hCtl_RenameMe_Locations fnc_RenameMe_Locations_OnChange

 ${NSD_CB_AddString} $hCtl_RenameMe_Locations "Select Your Location..."

 ${NSD_CB_AddString} $hCtl_RenameMe_Locations "Location 1"

 ${NSD_CB_AddString} $hCtl_RenameMe_Locations "Location 2"

 ${NSD_CB_AddString} $hCtl_RenameMe_Locations "Location 3"

 ${NSD_CB_AddString} $hCtl_RenameMe_Locations "Location 4"

 ${NSD_CB_SelectString} $hCtl_RenameMe_Locations "Select Your Location..." 

Function fnc_RenameMe_Locations_OnChange

 ${NSD_GetText} $hCtl_RenameMe_Locations $0


 ${If} $0 == "Select Your Location..."

   < CODE TO REMOVE/HIDE DROPLIST >

  ${ElseIf} $0 == "Location 1"

>#    Var /GLOBAL hCtl_RenameMe_DropList1

#    Var /GLOBAL hCtl_RenameMe_DropList1_Font


   ; === DropList1 (type: DropList) ===

>#    ${NSD_CreateDropList} 89 132 121 21 ""

#    Pop $hCtl_RenameMe_DropList1

#    CreateFont $hCtl_RenameMe_DropList1_Font "Microsoft Sans Serif" "8.25" "400"

#    SendMessage $hCtl_RenameMe_DropList1 ${WM_SETFONT} $hCtl_RenameMe_DropList1_Font 0

#    SetCtlColors $hCtl_RenameMe_DropList1 0x000000 0xFFFFFF

 < CODE TO CREATE/UNHIDE DROPLIST >


  ${ElseIf} $0 == "Location 2"


 < CODE TO CREATE/UNHIDE DROPLIST >


  ${EndIf}


>FunctionEnd

The above commented out code creates it on the fly as necessary, just not sure how to remove a droplist. If I can figure out the show/hide for an individual droplist, I will create it and just hide it by default and then just set an option to show it as necessary.. Any Ideas???

Thanks,

This should work:

ShowWindow $hCtl_RenameMe_Locations 0

Where $hCtl_RenameMe_Locations is the DropDownList variable you Popped after creating it, and 0 is SW_HIDE. http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx

Works perfectly... Was stuck on ShowWindow being for more than just the target element, like the whole page, but I stand corrected... Thanks...

  ${If} $0 == "Select Your Location..."

    ShowWindow $hCtl_RenameMe_dyn_DropList1 0

    SendMessage $hCtl_RenameMe_dyn_DropList1${CB_RESETCONTENT} 0 0 $0

    ShowWindow $hCtl_RenameMe_dyn_Input1 0

   ${NSD_SetText} $hCtl_RenameMe_dyn_Input1 ""

 ${ElseIf} $0 == "Location 1"

    ShowWindow $hCtl_RenameMe_dyn_DropList1 1

    ShowWindow $hCtl_RenameMe_dyn_Input1 0

   ${NSD_SetText} $hCtl_RenameMe_dyn_Input1 ""

 ${ElseIf} $0 == "Location 2"

    ShowWindow $hCtl_RenameMe_dyn_DropList1 0

    SendMessage $hCtl_RenameMe_dyn_DropList1${CB_RESETCONTENT} 0 0 $0

    ShowWindow $hCtl_RenameMe_dyn_Input1 1

  ${EndIf} 

Obviously there are cleaner ways to do this, I will eventually call a fnc_clear_form so there is not so much repetitive code, but otherwise, this gets'er done..

Thanks,
