how to get what day from ActiveX calendar control

[Anne Zuo]

Hi All,


I am using an ActiveX calendar control. When user click it, I want to know what day it is, Monday, Tuesday,.......Sunday.  Anyway to do it?

Thanks a lot for any help.

You need to register a VI to be used as a callback. If you open the Example Finder (Help -> Find Examples), and search for "ActiveX" there's a couple of examples on how to register callback VIs. The attached example is something to get you started. It includes the callback so you can see how to access the control's properties and use those to figure out the day of the week. You'll need to use the selected day to figure that out. I've gotten you started on it - I'm sure you can finish the numerical calculations.

Hi Smercucio. I tried to help Anne Zuo as well but you were faster. In addition I still cannot wire the callback VI. I use Microsoft Month view control 6.0. I made the VI reentrant and strictly typedef. So why the hell I still cannot wire it? Thanks Message Edited by ceties on 05-28-2008 04:01 PM

It's because your event data and ctlref are not correct.  On the Reg Event node in Calender_cet.vi, right-click on VI Ref and select create callback VI.

Ouch! I didn't know that the VI is generated automatically. So thx!

Thanks a lot for your help, but I still couldn't get it.


Click on 1st day of any month, any year, the result will be same:

Day:1; FirstDay:2;Quotient:0;Remainder:1


and apparently they are different day of week. 


Some trick I miss?

Thanks.

Try this

The "trick" is that the code isn't finished, as I explained, and indicated in the callback VI. The callback VI is always picking "Sunday". I was showing you how to use a callback to get the calendar values when you click on a date, which is what you need to do. As for calculating the day of the week you can try to figure out how to do it from the "day", "month", "year", etc. or you can use the technique found in HOW TO MENTALLY CALCULATE THE DAY OF THE WEEK FOR ANY DATE.

I'd like to try, but maybe I don't have that control and it tells me "Control couldn't be loaded".

I should really go and sleep. I renamed it that was the problem. So once again and properly

EDIT: For some reason during the upload the system adds "1" to the names. SO just rename "CallReg_v31.vi" to "CallReg_v3.vi" Or you just don't have this Active X.
