I use this procedure to open my inbox:
ShellExecute := define_external('ShellExecuteA', hwnd::(integer), lpOperation::string, lpFile::string, lpParameters::string, lpDirectory::string, nShowCmd::integer, 'RETURN'::integer, LIB = "C:\\WINDOWS\\SYSTEM32\\shell32.dll"):
OpenBrowser := proc(someURL::string := "http://")
ShellExecute(0, " ", someURL, " ", " ", 1); NULL;
Case 1: I entered the correct email address of my friend who sent me the mail
As a result, the content of the message I received was opened with full information.
Case 2: When I enter an arbitrary email address that is not my friend, the result is that no content is displayed.
On the email there is only the message: The conversation you requested could not be loaded.
May I ask: Is there any Maple command to return true in case 1 and to return false in case 2 ?
Thank you very much for your help !
