this is my code

C#

int i = 0;
           foreach (string item in Properties.Settings.Default.DatesEventNames)
           {
               //add the headings
               if ((i++ % 3) == 0)
               {
                   //add label
                   Label neweventlabel = new Label();
                   neweventlabel.Content = item;
                   SP1.Children.Add(neweventlabel);

                   DateTime yourDateTime = DateTime.Parse(item + 1);
                   DateTime yourDateTime2 = DateTime.Parse(item + 2);

                   //add progressbar
                   ProgressBar pb = new ProgressBar();
                   pb.Maximum = (yourDateTime - yourDateTime2).TotalDays;
                   pb.Value = (yourDateTime - DateTime.Now.Date).TotalDays;
                   pb.Height = 20;
                   SP1.Children.Add(pb);
               }
           }

the error is, only the one label is posted, its meant to post the progressbar too, so I found out where the error is it is

C#

DateTime yourDateTime = DateTime.Parse(item + 1);
                   DateTime yourDateTime2 = DateTime.Parse(item + 2);

but I don't understand why its not working.

this is what it looks like in the string collection

eventname<br />
9/01/2013<br />
20/01/2013

so this is what its ment to look like in the program

eventname
|-----progressbar-with the values-----|

its just a ruff visual of it.
can some one please help me solve the problem?

Solution 1

It is not working, it cannot compile. What's your problem, ashamed to admit it? :-)

This is just gibberish: DateTime.Parse(item + 1); item is string, that's correct, because the method Parse expects a string parameter, but you cannot add 1 to a string.

It's not even clear what could you probably meant by "+1". Adding a day? an hour? If this was something like this, you should first parse item to obtain an instance of DateTime and then use one of the functions adding some time span to the resulting time.

in (item + 1) trying to select the item, for example, in the stringcollection, lets say i have 5 lines, i want to select line 3, and i do this by, selecting line 2 and adding 1

Sergey Alexandrovich Kryukov 9-Jan-13 2:28am

No, you are not trying to select the item. I already explained...
I am tempted to say "stop developing UI, you are not ready yet, first learn some elementary basics of programming"... you see almost said that. :-)

lets say i got 5 strings in my stringcollection, and they go in order like this

yo1
yo2
yo3
yo4

I want to select "yo3"

I already know the line number of "yo2" but not "yo3"
So, because I don't know "yo3"
I will need to use an index or something
because its an unknown, I want to do somthing like

select the index in line 2 (which is "yo2") then add 1 to the index in the stringcollection, which will bring me down 1 line, and then it will give me "yo3"

Check my solution. since your collection is fixed you can access your data with index you want.

Jibesh 9-Jan-13 2:55am

hmm... seriously .. you should start looking how Collection works, and before that you must know what your code does.

you are already iterating a collection so use an counter to check the iteration. do spend learning some basics before going further it will save your time for future development.

how do i delete this question? because apparently this is useless

Sergey Alexandrovich Kryukov 9-Jan-13 19:43pm

I would do it, but we usually don't remove questions which already got answers, because the inquirer is not the only reader of them.

well none of them are the answer, i'll restart the question, don't think people understand the question

Sergey Alexandrovich Kryukov 9-Jan-13 21:00pm

People don't have to understand it all, especially when you do net really collaborate. Do you know this well-known proverb: "I don't need to eat all the egg to know it's bad"?
I've shown you one bug, this should be enough to make a first step, and then go ahead. You, however, did not show any sign that you sorted it our or even tried.
However, the problem is that you maybe not ready to do what you try. Go back, learn the basics.

As per your comments you should try the following code to solve this.

C#

DateTime yourDateTime = DateTime.Parse(Properties.Settings.Default.DatesEventNames[1]);
DateTime yourDateTime2 = DateTime.Parse(Properties.Settings.Default.DatesEventNames[2]);

mean time you should be careful in accessing this collection. check the array count else it blows your application.
