Draw and Erase Text

OK,

I've failed miserably but how do you write text to a gui window and later erase that text.   I've been using TextOut with

         ret = SetROP2(hDC, R2_XORPEN)
         iret = SetBkMode(hDC,TRANSPARENT)

but that just doesn't work. My gui window is MM_TEXT. Any suggestions will be greatly appreciated. Everything is being done in IVF 2016 with help from MSVS 2013.

Thanks,

Brooks
