I could have clarified "form", since I'm referring to WinForms applications. "Form" in this context was actually meant as an input form, not the window itself. But I think I can follow that same concept. I'll give it a try.

Oh duh... OK...
You can reset a form...
myForm.Controls.Clear();
myForm.InitializeComponent();
|

Thank you, I'll give this a try. Very simple and seems like it should do exactly what I need.

The only problem with doing that is that if your form code maintains a state it's not going to get reset. It'll only destroy and recreate the controls to however you had them set in the Form Designer and property settings.
|
|
|
|
|
But isn't that what he wants? Instead of "clearing" everything, which sets textboxes to empty string and whatnot, I thought he wants the "default" values from the form designer to show up - otherwise, yeah, you only need to Form.Controls.Clear() and call it good.
|
|
|
|

I don't let the controls determine the status of any state machine I've got behind the forms. The state machine determines the state of the controls and the controls reflect that.
I know there are plenty of cases where the app or form is so simple that there is no state machine behind it, but there are too many noobs out there who rely on the controls to "store" data and determine the state of a form or app based on, say, the text of a button, or if it's enabled or not.
That's not the proper way to do it.

|
|
Yeah definitely incorrect designs would make it more tricky, but I get the impression this particular form doesn't have any initial state other than what was set in the designer...
|
|
|
|

While it's a good idea  , I'd still call it a hack, unless xml-documentation is included with some explanation like Dave posted. Private members would not be reset, and the "OnCreate" event wouldn't fire on it's own. It might contain some "form magic" for setting the form up as well.

Well, I used the "hack" and it works just fine. I'm still going to experiment with other options based on everyone's input. But for my purposes, the "hack" gets the job done for now at least.

I just re-load the page...
If you're currently on "MyPage.aspx" this will reset it.
Response.Redirect("MyPage.aspx", true);

Form.Controls.Clear();
InitializeComponent();
Alternatively, loop all controls using reflection (no, it ain't that slow, just a bit of an exercise to get recursion working) and clear them.
How do your edit-forms look like? Mine could be explained as a PropertyGrid on a dialog-form. It has an extra button called "reset", which just reloads a cloned object into the propertygrid.
It's not a real property-grid anymore; it's a custom control that behaves in a similar way (in code), but that renders a more 'traditional' winform.
I choose this architecture out of convenience; a single modification in the object, and it's pushed to a Memento-pattern (undo/redo stack). When closing, the content of both get serialized and saved. When loaded, both are restored - it makes users happy when they find out that they can "undo" yesterday's changes, even if the PC was turned of in the mean time.

THAT, is hard freeking core, dude. I like it
As noted before though, I think the only way to make it behave like a 'new' form is to have it be a new form... but if it's your main form or something, that might require hacking program.cs.

Can be a bit confusing though; most users expect an empty undo/redo-list when they launch an application.

If you are using wpf with MVVM then all you have to do is make the VM serializable, and save it.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Try giving an example of what is giving you a problem.

Is requested regularly, and there are quite some examples on the web. Simply download the Time Tracker Starter Kit[^].

This is more of a SQL considering you are looking for the structure of the table.
Try looking at samples across the internet to identify your fields correctly.

I really dislike this MO; "go find a decent db on the netz".
Make a list of all the facts that your information-system needs to administer. Group the facts into logical groupings. Make sure every fact is atomic; if it's not, split it into multiple facts.
Iterate each group, giving it a descriptive name for the fact-collection. Now, iterate again, and find the fact (or facts) in each group that uniquely identifies a row/record/tupel/object whatever you call it. That's the fact(s) (or field(s) or column(s)) that represent the primary key.
Next, iterate all those tables/groups of facts again, and remove any fact that's not being identified by it's key.
This is called "database-design and normalization", and is a bit more work than described above.
And no, a housenumber "21a" does NOT consist of two facts, that's ONE fact. (Person has one housenumber, which happens to be a combination of two real-life things. These are, however, never used irl as separate facts, and hence, should not be modelled as different facts. Same goes for street and housenumber; if you need an address, reserve space for an address, not a street and a housenumber.
