We have some problems, dealing with the MSWindows-SDK. 



1. We are trying to create modeles-Dialogs. Within these Dialogs

   we have some fields that are editable but sometimes they are

   not. This depends on some data in other fields. To show the

   user, which field is editable, we want to temporary disable/

   enable the Border arround the Edit fields. The first imagination

   to do so was, simply use SetWindowLong(hWnd,GWL_STYLE...) to

   change the WS_BORDER style from the Edit-Control-Window. But

   no success. After using SetWindowLong, the Border arround the

   Edit fields remains visible/not visible, depending on the

   WS_BORDER flag, set during creation of the Dialog. To work arround

   this problem we will switch to use two types of Edit-Controls,

   one w/wo the WS_BORDER flag. But this will cost more Code and time,

   and I feel that there must be another way to enable/disable the

   Border arround an Edit-Control. Maybe anyone has some suggestions for

   us to do so.



2. Our second problem is, that we want to use more than one Edit-

   Control with each more than about 32K of memory. Because of the

   use of the LocalHeap, this seems not to be possible. But someone

   told me to GlobalAlloc Memory and then to pass the GlobalHandle to

   My Edit-Control as the hInstance parameter of the CreateWindow

   function. My code looks like that :



	   hGlobalMemory=GlobalAlloc(GMEM_MOVEABLE,32760L);

	   hEditControl=CreateWindow("Edit",....,hGlobalMemory...);



   But does not work. 

   Maybe anyone has a solution to this problem. 





   Thanks and regards
