Tab Control - Page Title

[George Deluca]

Is it possible to change the title shown on a page tab after it has been created? Or do you have to effectively delete/recreate the page?

I'm trying to plow through MSDN but can't find anything close. Attempts with varieties of SET TEXT and using handles of the page and/or Tab control seem to do nothing.

TCM_SETITEM is what you need. I am not sure if DDT offers a command to do it?

#Compiler PBWin 9
#Compile Exe
#Dim All

#Include "win32api.inc"

  mask As Dword
  lpReserved1 As Dword

  cchTextMax As Dword
  iImage As Dword
  lParam As Long
End Type

%TCM_SETITEM = 4870
