Didn't someone write a userlib that had a date requester? I know about the calendar and date picker API gadgets but I need something that pops open to prompt for a date and provides and easy way to retrieve it..

On a side note, does anyone have any information on trapping selections from a calendar gadget (so as to make a requester like the one I just described)?

Thanks!

dont you have PureVision? It has a date picker. Try the examples, that is one that retries the data.

Sure I do, and I know about the date picker and cal gadgets. What I need is a *requester*..

I could swear that someone wrote one back in the summer but I can't find any mention of it now..

I recently started working on Datepicker lib, but I don't think it's going to suit your needs. If time permits, I'll see if I can come up with a requester type Datepicker as well.

On a side note, does anyone have any information on trapping selections from a calendar gadget (so as to make a requester like the one I just described)?

You may find some useful info in this related thread.

> What I need is a *requester*

What exactly do you mean by this? I've got a date picker example that seems
to do what you want... ie. it's like a string gadget with an arrow on the end that
you click... if you click this arrow, a small month view comes up and you can
select a date. If you put this date picker in its own pop-up window, then isn't
that what you'd want? Just trying to understand what you need.

Can you
draw a pic or something to help me visualize your need?

I need a date or calendar picker to be on a panel, but that isn't possible without some hacks (though there is hope for a native date gadget!). My intention is to take it by having a read-only string gadget with a image button beside that, when clicked, displays a calendar and puts what ever date they select into the string gadget..

Here's where I'm at with my lib thus far. I've taken the key parts of the lib and put it into this small example. You select a date then Ctrl + Left click into a readonly string gadget.

Code: Select all

#GDT_VALID = 0
#GDT_NONE = 1
#DTM_FIRST = $1000
#DTM_GETSYSTEMTIME = #DTM_FIRST + 1
#DTM_SETSYSTEMTIME = #DTM_FIRST + 2
#DTN_DATETIMECHANGE = #DTN_FIRST + 1 
#DTN_DROPDOWN = #DTN_FIRST + 6 
#DTN_CLOSEUP = #DTN_FIRST + 7 
#MCM_FIRST = $1000
#MCM_GETCURSEL = #MCM_FIRST + 1 
#MCN_FIRST = -750
#MCN_SELCHANGE = #MCN_FIRST + 1
#MCN_SELECT = #MCN_FIRST + 4
#MCN_GETDAYSTATE = #MCN_FIRST + 3
