I have an application which uses mutliple forms for different tasks,
all of which are mdi child forms to the applications MDI Parent form.
One of these child forms (form1) will be used to select a record from
somewhere within a hierarchy (using a treeview and listbox to narrow
down the search) and then the details from this record should be
displayed on an entirely different child form (form2) by the click of
a button.
What I want to know is how do I get this click of the button to open a
new form, passing over the ID value of the record selected?
I'm sure it has something to do with constructors, but as I've never
done it, I don't know how.
Any sample code for the form2's constructor, and how to open and pass
this value to form2 will be greatly appreciated. 2 2327

You don't need to muck with the new form's constructor. Just create a
property in the new form and after you instantiate the new form and
before you show it, set the value of the property to the value you
want to pass to the new form. Then after the new form is shown it can
access the value from it's own local property.

Perfect... Just what I was after.

Hi folks,
The python can only support passing value in function call (right?), I'm
wondering how to effectively pass a large parameter, such as a large list or
dictionary?
It could achieved by pointer in C++, is there such way in Python?
Thansk in advance.

Hi,
I have been experiencing a problem passing a LIKE statement in the WHERE

separately.
However, in an attempt to work around the problem, I thought of using

WHERE).
In the parent form, I have generated a RecordSet (RS) with the information

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
