Yes, if you do division using integers the result is an integer (as you've found).

Double i_decel_rate = ((Convert.ToDouble(textbox1.Text) * 10000.0) / Convert.ToDouble(textbox2.Text));

Hi friends,

Thanks to those who answered my first question. Now I have other.
Do you think it is worth it to buy books for C# 2005 and .Net 2.0 when VS 2008 and .Net 3.0 are around the corner?
I'm afraid of buying those books, eat them and then, Microsoft changes the examinations to the latest technology.

What do you think?

I'm thinking in buying this pack:

incrmenting by 01 instead of 1

Hi
the code below incrments by 1 each time and adds1 to the end number, is there a way for it to increment 01,02,03 rather then 1,2,3

string[] split = db.Split('_');

string s_number = split[1];
int i_number = Int32.Parse(s_number);

i_number++;
s_number = i_number.ToString();

db = split[0] + "_" + s_number;

cheers

You can use String.Format()[^]. You can find the right format string in the examples.

Standards are great! Everybody should have one!

1 is a number which you can increment.

01 is a string representation of a number. You cannot increment a string as it has no real meaning to do so.

You should increment you number (1) and then apply string formatting to that number (myNumber.ToString("00")) to get the required format.

Guess you missed my other reply Laugh | :laugh:

Yeah, either .Format("00");
or like i said last time .PadLeft(2, '0');

ok so should it be added somewhere in the line below as this is the entire format of what is being outputted?
db = split[0] + "_" + s_number;

10-Dec-07 3:09

Instead of getting someone here to hold your hand all the way through... try some stuff out yourself next time given the hints that have been provided.

db = split[0] + "_" + s_number.ToString("00");

eyeseetee10-Dec-07 3:22

10-Dec-07 3:22

well done thats great thats what ive already tried which is why i posted the question D'Oh! | :doh:

db = split[0] + "_" + s_number.ToString("00"); this does not work error message is there are invalid areguments in the code

eyeseetee10-Dec-07 3:27

10-Dec-07 3:27

it should be this:
s_number = i_number.ToString("00");
not
db = split[0] + "_" + s_number.ToString("00");

Problem with datatable

Hi,
I have a datatable which is going to fill from a if statment (I mean I don't know which record is going to returned) and after the data is returned i want to be able to edit or delete the returned records.
(the IF's are a search statment all on one table and diffrent columns)
so when S.O wants to delete a record i want to refresh the Grid which is filled with datatable.
how can i refresh the datatable.

(I hope i was able to express what I mean)
please help me. Big Grin | :-D

I strongly advise to use SQL to get only the data you want.
If this is not possible you will have to use loop to step through all returned rows and fill a new DataTable with only the rows you want (ImportRow) (no a DataView won't help if you can't use SQL to filter).

If you may use LINQ it's getting simpler - just use where with your IF
(for example:

<br />
<br />
var FilteredDT = from c in originalTable<br />
                 where (c => (statements from the if for c - for example c.Name.StartsWith("x")))<br />
                 select c;<br />

webbrowser progressbar control

I have the following code and one progress bar (websites are navigated at run time and web site list may be more than this)

<br />
//websitelist[]={"google.com","yahoo.com","codeproject.com",....};<br />
for (int kk = 0; kk < 3; kk++)<br />
{<br />
web = new WebBrowser();<br />
web.Url = new System.Uri(websitelist[kk], System.UriKind.Absolute);<br />
web.Navigate(websitelist[kk]);<br />
hashTable.Add(kk, web);<br />
}

How can I get summation of progress of all webbrowsers in just a single progress bar i.e., their progress can be shown in single progress bar? If I am having a single webbrower I can get progress values by using their event handle, but when I have run time browers control and going on increasing how can I use event handling for all browsers(stored in hashtable as objects)

like :

foreach (int kk in hashTable.Keys)<br />
{               <br />
......<br />
//WebBrowser Web = (WebBrowser)hashTable[kk];<br />
//progressBar1.Value += Web.currentprogress; <br />
...<br />
}

I don't think you can get the progress of the web control (no use anyway because if you set the URL or Navigate in a WebBrowser-Control the statement will only return after the site was loaded - so you would have to use a asynchron version).

Why don't you just use (kk+1.0)/websitelist.Count as a hint?
(If not you will have to load the sites yourself ... I don't think you will enjoy the work)

Thanks for a reply!

websites are navigated for a long time in hashtable. I don't know when they all are finished their work(navigation). There may be speed bandwidth problem, so I have to check their current progress. I think counting will not solve this problem.

Hi,

each WebBrowser generates its own WebBrowserProgressChanged event, and the
WebBrowserProgressChangedEventArgs offer both current and max values.

From all these numbers you can calculate overall progress any way you choose,
one possibility is 100% * sum(current) / sum(max)

(be careful with the initial situation when not all of the current & max values
have been reported yet).

problem with if statement

Re: problem with if statement

10-Dec-07 0:27

Hi
I have the following code which is counting how many instances of room_code there are in table room_schdule. I know there is two counts of it in there, but my if statement at the bottom is not working, any clues?
cheers

string test0003 = "Select count (room_code) from room_schedule where room_code = '" + room_code + "'";

string max5;

SqlCommand cmd01 = new SqlCommand();

cmd01.Connection = con2;
cmd01.CommandText = test0003;

max5 = cmd01.ExecuteScalar().ToString();

if (max5 < 2)(it shouldnt perform this statement but it is)

do something

else

CKnig10-Dec-07 0:38

Try

<br />
int imax5 = Convert.ToInt32(cmd01.ExecuteScalar());<br />
if (imax5 < 2)<br />
{<br />
 ...<br />
}<br />

The problem is "string" < "integer" - I wonder why your compiler is processing this without warning.
