Hi all,
as you can see from the level of my question, i am pretty new to c# and
programming in general.
situation: i would like to update the UI of a form (main form of my
application) from a second form (which was called from the first).
Ideally when a button on the second form is pressed, the first one
(main form) should update/refresh its UI.
But it would be also fine to have the first form refreshing when the
second form is closed/disposed.
Can you help me please? Thanks in advance.

Try adding an event to the second form and catching it in a handler on the
first form. Hook up the handler after creating the second form but before
showing it.

Hi,
There are several ways of doing this:
- Pass a reference to the first form in the constroctor of the second. then
you should declare some public methods in Form1 they will do the update on
it, this method will be called from Form2.
- Make Form2 declare some events that Form1 can subscribe to and update its
UI as needed.

Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

Hi,
I've been having this problem for some time with Web Forms:
I have a web app that sends data to a service when the user presses a
button. Based on the data, the server will send several replies. Since
there is no way for a service to post to a client, I am using a thread
on the client that polls the server for updates.
(Feel free to recommend changes to that as well)

I have an Access 2002 database that has a form that can be used to review individual records.

Hi,
I have a win form and a class library, in the library I do a long
running proccess (processing a large number of files), I am planning to
do this in another thread.
What are my options for updating the progress bar in the win form ?. I
would like the class library to be as stand alone as possible, so what
is the best way to expose the state of the long running operation and
what is the best way for the win form to consume it ?.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
