ComboBox and StringGadget initial "Choose" text.
Compile as unicode unless you ant to mess around with PeekS and PokeS to convert the text for SendMessage.

Code: Select all

#ECM_FIRST=$1500
#EM_SETCUEBANNER=#ECM_FIRST+1
#CB_SETCUEBANNER=$1703

  If OpenWindow(0, 0, 0, 270, 140, "ComboBoxGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) And CreateGadgetList(WindowID(0))
    ComboBoxGadget(0, 10, 10, 250, 100, #PB_ComboBox_Editable)
    AddGadgetItem(0, -1, "ComboBox editable...")
    SendMessage_(GadgetID(0), #CB_SETCUEBANNER, 0, "Choose or enter:");
    ComboBoxGadget(1, 10, 40, 250, 100)
    For a = 1 To 5 : AddGadgetItem(1, -1,"ComboBox item " + Str(a)) : Next a
;    SetGadgetState(1, 2)    ; set (beginning with 0) the third item as active one
    SendMessage_(GadgetID(1), #CB_SETCUEBANNER, 0, "Select an option:");
    StringGadget(2, 10, 70, 250, 20,"")
    SendMessage_(GadgetID(2), #EM_SETCUEBANNER, 0, "Enter text:");
    Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
  EndIf

Doesn't work unless you compile it as unicode compatible, then it works well.

Well considering this is for Vista I don't think that is an issue

After all, 2000, XP, 2003, Vista, 2008, are all unicode. So unless you need to support Win9x I do not see any reason to compile as anything, my default is always unicode these days.

Thanks for pointing that out though, not sure about SendMessage but I know some API calls do not always have A and W variants.

So if anyone are making a Vista or Vista compatible app and want to use this feature then PeekS() and PokeS() must be used to convert a ascii string to unicode before sending the text to the gadget via SendMessage().

Oh yeah, you also need XP Theme enabled for these to show anything.

No idea, it seems automatic and part of the OS GUI. I have not checked if this works on XP SP2 it might. I doubt it works on 2000 though.
