    How to marshal things ...

    Hi!

    I wonder, how the declaration of the following c-function must look like in
    VB.NET

    STATUS LNPUBLIC ConvertTextToTI MEDATE(
    const void far *IntlFormat,
    const TFMT far *TextFormat,
    char far * far *Text,
    WORD MaxLength,
    TIMEDATE far *retTIMEDATE);

    Especially the pointer to pointer of Text is causing me headache.

    The Second Question is, how to declare a struct with string-members like:

    typedef struct {
    ....
    char TodayString[YTSTRMAX]; /* String denoting current day */
    ....
    } INTLFORMAT

    Regards,
    Markward

      I apologize that I'm not a C programmer, so I can't help you convert
      the code to VB. But I think I may still be able to help...
      STATUS LNPUBLIC ConvertTextToTI MEDATE(
      const void far *IntlFormat,
      const TFMT far *TextFormat,
      char far * far *Text,
      WORD MaxLength,
      TIMEDATE far *retTIMEDATE);
      This turns some text (a string) into a DateTime right? If so just use
      DateTime.Parse( string) instead - no need to create your own method.

      While you could create a structure for this, it seems like a waste to
      me. If you need a string denoting the current date just use
      DateTime.Now.To String("M/d/yyyy")

      Thanks,

          Hi!

          Thanks for your reply, but the datarype here is TIMEDATE, wich is a Lotus
          Notes specific type, different from DateTime.

              Sorry about that - I was assuming the timedate was the C type for
              datetime. I'm guessing that Lotus Notes has an SDK available for
              VB.Net? If it does check to see if it exposes the TIMEDATE type,
              because then you may be able to cast the datetime into the timedate
              using DirectCast or CType.

              Thanks,
