ComboBox Text won't clear.
Hi there,, , Does anyone know how to clear the text dispplayed in a combo box? Mine just holds the last value and doesn't overwrite it when I tab back to it ideally I want it cleared and ready for the next entry. , , I've tried setting .Text := ''; but it doesn't work even if I set it to '1'; it doesn't display a 1 only the previous value. The whole text line seems to be higlighted rather than just the text. Any ideas?, , Thanks, Mully

Calendar VCL with multiple date display

I have written a little programs that keeps information on relatives and friends and I would like to show on the current month's calendar all the dates on which birthdays may fall.

 

Is there a free Calendar component  for Delphi 7 (or upwards) that allows for the display of multiple dates.

I can't promise that such a calendar component is in there, but have you investigated Project Jedi? http://www.delphi-jedi.org/

Try such a nice piece of code as

Calendar.Date:=Calendar.Date+31;, Calendar.Date:=Calendar.Date-31;

to Force that component +)

And it will bold the current month))

Using TWebbrowser to enter text and click button
Using TWebbrowser to access a web form with a few fields on it, and a couple of buttons. I want to enter some text into one of these form Fields, then click one of the buttons ('Search'), with delphi code accessing the page via TWebbrowser. I can access the complete HTML page source (is in a frame but i do a fool workaround to trick it into discarding the outer frame anyway).  I know what the button and the field names are. Having Zero luck with this so far, need a direction to be pointed in if nothing more.  Any Ideas?

Actually I made the TSpeedButton get focussed using the Enabled property. I initialised it to false. When I need to get the focus back, I just assign Enabled as true and it works fine. So initially all the buttons are not activated. Works fine I guess .. atleast for my application

I would imagine that if your timer is being checked every second, then you could also check the system time., , A significant difference from one timer check to the next could trigger a timer correction based on the difference between a previous (captured) system time and the current system time., , No doubt there is a more refined and accurate solution but for simply triggering a shutdown this seems OK.

Can't control visibility in DBCtrlGrid ?
I am using a DBCtrlGrid to display several records on screen at once. The control grid has a DBCheckBox and a DBEdit on it. I am trying to control the Visible state of the DBEdit according to the Checked state of the DBCheckBox., , When a checkbox is clicked (I am using the OnClick event), the corresponding DBEdit behaves correctly, however all the other DBEdits (for the other records) change state whenever I move to another record. , , I notice that the controls placed on a DBCtrlGrid actually appear with the Form as their parent in the object inspector., , Is there any way to determine which instance of the controls I am dealing with at any one time and limit the effects to just one record at a time., , Thanks for any help, , RonR , --------------------------------------------------------------------------------
