when to use what type of conversion? For example when writing a class that would update a record I never know when to use
1. Convert.To...
2. int.Parce(...)
3. (int)....
What is the difference?, when would you use which?
SQL = " UPDATE Search WITH (ROWLOCK) SET "
+ " Keyword = " + (string) OR (Convert.ToString) (Keyword)
+ ",PageRank = " + [code]....
i am using a search box for my application which returns a dataset. however when i click on the search button it returns an empty table result. how could i add validation so it doesnt accept empty strings or numbers.
View 9 RepliesI'm new to .NET and converting and proper way to convert strings to other values. Specifically, here is a situation I'm facing:
I'm returning two values from a datasource as strings. One values is a representation of a span of time, and another is a count of how many attempts to access a system took place within the span of time.
Given these parameters (for example):
Span of time: 00:01:00
Attempts: 13
I'd like to calculate a third value that shows how many seconds each attempt to connect took place during that span of time. This involves converting the time span to seconds and then dividing by attempts. Where I am getting lost is with the conversion of types. I know the span of time needs to be converted to a date, reduced to seconds, then converted to a number to be divided by the attempts field, also converted to a number.
I've been playing around with code segments like this all morning to no avail:
VBNET Code:
Dim thisTime As String = "00:01:00"
Dim thisAttempts As String = "13"
Label1.Text = thisTime
Label2.Text = thisAttempts
Label3.Text = Math.Round(Integer.Parse(Convert.ToDateTime(Label1.Text)) / Integer.Parse(Label2.Text), 2)
I am working on a query to pull the revenue for the last 7 days, as individual days, to be used in a bar graph. My query does what I want it to:

re: How to Compare Strings
String.Equals() will check for same string
i am developing an application using ASP.NET with C#. and SQL SERVER 2005. in my application i have number of strings like:
1. 120 count
2. 60/2.75 oz pkg (2 cookies/pkg)
3. 100/.9 oz.
4. 3.05 oz. patty 105 servings per case
5. 19# average(Catch Weight Item)
6. 2/ 8-9 lb. average weight per case
7. 10#
8. 160 nuggets = 32 servings per case
9. 320/ 1 oz portion (20# Case)
10. 213/2.25 oz. servings (6/5 lb. bags) etc.
from the above strings i have to get only numbers like:
from 1 i have to get 120
from 2 --------- 60/2.75
from 3 ---------- 100/.9
from4 ---------- 3.05
from5 ---------- 19
from 6 --------2/8.9 etc.
how to get the numbers from a string?
This seems very basic but I can't seem to find a fast way to do it..
I have the following numbers:
5, 3, 10, 52, 1
I want to order them in the correct format from 1 to 52 and be able to point out which one is the highest, which one is the lowest, which one the second to highest, etc.
I have a div element which has these css attributes :
HTML
<div class="messageContainer"></div>
CSS
.messageContainer {
margin-left: 2px;
background-color: #F7F5F2;
width: 100%;
min-height: 50px;
border: solid 1px silver;
padding-left: 5px;
margin-top: 3px;
}
When putting this html portion inside the div element : do the things respectively:
<ol>
<li>
Create button control
</li>
<li>
Assign it to the main user
</li>
<li>
Let me know what happened
</li>
</ol>
This is how it shows on the page: (Please look at the numbers) So the question is why this is happening?Why are the numbers are appearing outside of the div element. I used:
.messageContainer ol
{
list-style-position:inside;
margin-left:5px;
}
which worked just fine but now this is what happened.
How to do this:
10 becames 10.00
12.3 becames 12.30
14.23 becames 14.23
I need to post an xml string to another website. I can't create an xml file, because some of the content is dynamically created. The two lines that are causing me problems are
sPostData = sPostData & "<?xml version='1.0'?>"
sPostData = sPostData & "<?qbmsxml version='4.1'?>"
The receiving site expects to see
<?xml version="1.0"?>
<?qbmsxml version="4.1"?>
not
<?xml version='1.0'?>
<?qbmsxml version='4.1'?>
The conversion from double quotes to single quotes isn't being accepted. So how can I send the string so that the versions are surrounded by double quotes?
I have an assembly called like X.Common.DLL. There is some resources files for multilanguage app. Let's say it Language.resx Language.en-US.resx....etc.... I have a web application which contains this above dll as reference... So how can I use this resources file in my web applications markup side?
Text="<%$ Resources:Class, ResourceKey %>" is not valid because of "Class" name is in another assembly...

View 2 RepliesI want to check if two string are of the same length. I tried the following, but it doesn't work.

string passcnfrm = "1234";

Why does it not work? What do I need to change?
So, I've got an array, filled with data from dynamic input fields. the input fields are PIN, Name and Description... and the user can add as many "sets" of these three fields as they want.
This data goes into an array.
For example, the array may have
11111, Test Name, Test Company
22222, Second Name, Second Company
etc. etc.
I know I can see the values of my array, so if I were to take:
item(0) & ", " & item(1) & ", " & item(2)
my output would be:
11111, Test Name, Test Company
The problem I'm having, is, I need to write ALL of the groupings of three out to a file... and I'm stuck on how to do that. So, I need a way to loop through until the end of the array and get:
item(0) & ", " & item(1) & ", " & item(2)
(enter a line break)
item(3) & ", " & item(4) & ", " & item(5)
...
until the end of the array
I'm guessing I need a for-loop and a counter, but can't get the syntax correct.
This example works great with string variables in ASP.Net:
Session("Stocks") = "MSFT; VRSN; GE"
On a different aspx page:
Dim StockString() as String = Session("Stocks").ToString.Split(";")
for i as integer=0 to StockString.GetUpperBound(0)
dim x as string = StockString(i)
next i
But...I cannot determine how to take a number (as in val(txtNumber.text) and make it available on a different page.
In my webpage i use the following in order filling the listview control
<asp:ListView ID="ListView1" runat="server">
<layouttemplate>
<asp:PlaceHolder id="itemPlaceholder" runat="server" /></layouttemplate>
<ItemTemplate>
<tr>
<td><asp:Label ID="Label1" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans1") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans1Visible") %>'></asp:Label>
<br />
<asp:Label ID="Label2" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans2") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans2Visible") %>'></asp:Label>
<br />
<asp:Label ID="Label3" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans3") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans3Visible") %>'></asp:Label>
<br />
<asp:Label ID="Label4" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans4") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans4Visible") %>'></asp:Label>
<br />
<asp:Label ID="Label5" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans5") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans5Visible") %>'></asp:Label>
<br />
<asp:Label ID="Label6" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans6") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans6Visible") %>'></asp:Label>
</td>
</tr>
</ItemTemplate>
</asp:ListView>
Now i would like to add numbers to the labels before they are rendered. For example currently the data displayed are like
Tennis
Football
Basketball
Nfl
Nba
Polo
and the output i would like to have is
1. Tennis
2. Football
3. Basketball
4. Nfl
5. Nba
6. Polo
Could i use ListView1_ItemCreated or the ListView1_ItemDataBound event to achieve this? If that is true, could you point me a place to start? the list view is filled with
Dt = GetDataTable("SELECT Ans1, Ans2,Ans3,Ans4,Ans5,Ans6, Ans1Visible,Ans2Visible,Ans3Visible,Ans4Visible,Ans5Visible,Ans6Visible, From myTable WHERE CatID ='" & cat & "'")
ListView1.DataSource = Dt
ListView1.DataBind()

I am developing a site in Persian (it a right to left language), and it's supposed to be used both with IE7 and IE8. I don't have any problems with IE7 but in IE8 all my numbers show in English instead of Persian; ie instead of showing ١٢٣ , IE8 shows 123. I tested Culture and UICulture but they didn't solve the problem.
By a great chance, I found that if I Omit "DocType" tag from top of my pages this problem resolves, but some other problems appear like my Ajax popup dialog box won't work as it used to in both IE7 and IE8; I've also seen warnings that say CSS Styles may not work properly without "DocType" tag.
What's wrong with <!DocType>? And How can I solve my problem?
