Delphi MapiSendMail 在 Windows 7 64 位上崩溃

Question

我有 Windows 7 64 位，当我尝试第二次发送电子邮件或者有时甚至只是等待第一次发送邮件完成时，我的 delphi sendmail 崩溃了。同一应用程序适用于 Windows Vista。

以下是我发送邮件的测试过程:

procedure TForm1.SendMail(const Subject, FileName: String);
var tmpName2, PFullFilePath, PSubject : Array[0..MAX_PATH] of AnsiChar;
    MapiMessage  : TMapiMessage;
    MapiFileDesc : TMapiFileDesc;
    MError       : Cardinal;
begin
  with MapiFileDesc do
  begin
     ulReserved:=0;
     flFlags:=0;
     nPosition:=Cardinal(-1);
     StrPCopy(PFullFilePath, FileName);
     lpszPathName:=PFullFilePath;
     StrPCopy(tmpName2,ExtractFileName(FileName));
     lpszFileName:=tmpName2;
     lpFileType:=nil;
   end;

   with MapiMessage do
   begin
      ulReserved := 0;
      StrPCopy(PSubject, Subject);
      lpszSubject := PSubject;
      lpszNoteText := nil;
      lpszMessageType := nil;
      lpszDateReceived := nil;
      lpszConversationID := nil;
      flFlags := 0;
      lpOriginator := nil;
      nRecipCount := 0;
      lpRecips := nil;
      nFileCount := 1;
      lpFiles := @MapiFileDesc;
   end;

   MError:=MapiSendMail(0,Application.Handle, MapiMessage, MAPI_DIALOG or MAPI_LOGON_UI or MAPI_NEW_SESSION, 0);

   if MError<>0 then
      Raise Exception.CreateFmt(IntToStr(MError), [MError]);
end;

我收到的错误/崩溃消息:

看看这个 Link在 Embarcadero，这可能是一些 Unicode 问题。

希望对您有帮助。
