The event handler of your button click must take object as a first argument. That's why you are getting error.

I changed it to several different overloads, but still getting an error. Here is what it is now
private void btnCalcLife_Click(object sender, PumpTest pTest, EventArgs e)<br />
{<br />
intgrav(pTest);<br />
lblLife.Enabled = true;<br />
lblLife.Text = lblLife.Text + pTest.tlife + " Hours";<br />
}
I think I need to change this statement but dont know what to change it too
this.btnCalcLife.Click += new System.EventHandler(this.btnCalcLife_Click);

Why don't you have a look at documentation of button click event? You can't add additional parameter to the event handler.

As Giorgi said, you cannot change the parameters of the event handlers. For the Click event, you get the first object sender parameter, which is always a reference to the Button sending the event (you can cast it), and EventArgs e which is useless. Other events pass arguments (eg. location where mouse was clicked) in an EventArgs-derived second parameter.
If you create your own event, you should derive from EventArgs to create your own class for passing parameters to the event handler. But you can only do this for events you define, not for system-defined events.

Yea thanks for the help, I found an article online about setting up a ridiculous way to send something to a button through a wierd method but found it easier to just set up another Public instance of the class and set it equal to the class passed by the parent form.

No, nobody knows anything about it, and if they did they certainly would not create a Wikipedia page on that subject, and if they did you certainly would not be able to find it by searching with google.[^]
Good luck, you're going to need it.

The unfortunately reality is that a truly anonymous peer-peer application used to be possible through the use of Broadcast packets however the potential abuse is too high.
Read up on Tor and Onion routers for a good look at anon. Peer to Peer.

How can i load data from a comboBox into a datagrid.Basically the comboBox has a list of venues.When you select a venue the datagrid is supposed to display timeslots that are booked and those that are not booked for that particular venue.the data for the grid is taken from three different tables.(TimeSlot[with all the different timeslots]),(Venue[with all the different venues ])and (Timetable[with all the venues that are booked and the timeslots that they are booked for]).
Any code that will hep me with this problem will be greatly appreciated.

Does your custom control publish a public ImageList property?

Well i don't need an ImageList,that's a component. I just want a property that represents a list of images (List). The only thing I could think of is making the property of type Image[] and instantiate the array in the constructor, but I don't now the size of the array,that is why I need a List.
|

|
|
Sorry for the misunderstanding, I wrote ImageList,thinking of an list of images. Thanks
|

List doesn't have a control designer. Therefore, the designer doesn't know how to represent it in the designer. Roll your own collection class and define a control designer.
|
|
|
|
|
Ok,but my problem is that the control is in a class library,so how can that assembly know what resources my application has? I don't understand how can there is no way of choosing a list of images. There is a UITypeEditor for every collection,but it doesn't work for images,as images don't have a constructor. I am really confused now, I mean a list of images can be used by hundreds of controls...

Maybe if you can tell me how an Image Editor works,because all I really need is an Image Editor,wich lets me select multiple images (just like a listbox)

Hi
I try to develop an Web Application to manage films (a little bit like ImDB)
For the Edit part, I fill textboxes with a Linq query (on loading).
No problem to display the information in the different textboxes
But when I want to save changes into the database,
my textboxes are empty (according to the debugger) even if I put a value in it.
A part of my code to do this edition :
Loading :
<br />
DBMovies_ClassesDataContext db = new DBMovies_ClassesDataContext();<br />
<br />
int IdFilm = int.Parse(Session["idfilm"].ToString());<br />
<br />
var editedfilm =<br />
(from f in db.Films<br />
where f.id == IdFilm<br />
select new { Title = f.title, Title_o = f.title_original, Language = f.language, DateRelease = f.date_release, Genre = f.genre, Runtime = f.runtime, Plot = f.plot, Country = f.country }).Single();<br />
<br />
<br />
txtCountry.Text = editedfilm.Country.ToString();<br />
txtDateRelease.Text = editedfilm.DateRelease.ToString();<br />
txtGenre.Text = editedfilm.Genre.ToString();<br />
txtLanguage.Text = editedfilm.Language.ToString();<br />
txtPlot.Text = editedfilm.Plot.ToString();<br />
txtRuntime.Text = editedfilm.Runtime.ToString();<br />
txtTitle.Text = editedfilm.Title.ToString();<br />
txtTitle_o.Text = editedfilm.Title_o.ToString();<br />
<br />
Code to update values in DB :
<br />
<br />
DBMovies_ClassesDataContext db = new DBMovies_ClassesDataContext();<br />
<br />
<br />
int IdFilm = int.Parse(Session["idfilm"].ToString());<br />
<br />
var updateFilm = (from f in db.Films<br />
where f.id == IdFilm<br />
select f).Single();<br />
<br />
<br />
updateFilm.country = form1.FindControl(txtCountry.ID).ToString();<br />
<br />
updateFilm.country = txtCountry.Text.ToString();<br />
updateFilm.title = txtTitle.Text.ToString();<br />
updateFilm.title_original = txtTitle_o.Text.ToString();<br />
updateFilm.language = txtLanguage.Text.ToString();<br />
if (txtDateRelease.Text != "") { updateFilm.date_release = DateTime.Parse(txtDateRelease.Text); }<br />
updateFilm.genre = txtGenre.Text.ToString();<br />
if (txtRuntime.Text != "") { updateFilm.runtime = Int32.Parse(txtRuntime.Text); }<br />
updateFilm.plot = txtPlot.Text.ToString();<br />
<br />
db.SubmitChanges();<br />
<br />
and an exemple of my textboxes :
<asp:label id="lblCountry" runat="server" text="Country : "></asp:label><br />
<asp:textbox id="txtCountry" runat="server"></asp:textbox>
All the elements are working well
It's just the empty textboxes which ruin everything 
Thank you by advance
(and sorry if there are english mistakes)

The article provides a dll which you can add to your program as a reference and use classes inside it. No need to convert it in C#.

hi,
use datagridview for store multiple item. Let me explain
when user click on first time ok button then it add a row in datagridview and store the value of all three field in three column. and when user click on ok button second time, then it adds one more row for this entry and so on.
after that when user click on submit button, your program check each row of datagridview and save info.
hope this helps
