Not without seeing your code where the error occurs.

I'm in need of creating 200 bool random value (0 & 1). I'm coding like this :
Random rand = new Random()
rand.Next(0,2)
If i run in debug mode, the values it create is really random but if i don't debug, let it run automatic, all the values is just 0 or 1. Can someone tell me why and give me the direction to solve it?
Thanks!

If you look closely at the documentation for the Random class, you will see that it doesn't work when calls to Next are made in quick succession. That explains your debug vs non-debug behavior.
Instead of generating a random number between 0 and 2, wouldn't it be better if you generated random numbers (0 to size of int) and then converted them to binary? You can generate as many random numbers as you want until you get 200 binary digits.

I have a decimal value 23.25 . When i use the math.round(23.25,1) in VS.NET, the result is 23.2 but with the function: round(23.25,1) in SQL Server 2000, the result is 23.3 
How can i let them return the same value ?
Thanks!

See reply in the other forum you posted to (SQL/ADO/ADO.NET).
BTW posting the same question to multiple forms is considered to be rude, and will in some cases result in your question being ignored in all places.

I'm really sorry, Graham! I didn't mean it. Because i don't know which forum the question is suit to ... Besides, i used to face a similar situation. I used to posted a question in C# general but no-one answer me because posting it in SQL is more exactly ... So ... I'm really sorry. I will never repeat it again.
By the way, thanks your reply!

I host a object in a window service, and call it remotely from a particular client. I set the object as a Singleton mode in which it should return the same instance everytimes i remotely call. However, it happens to me that at some point, it will create a new instance of the object ???!!!!
What went wrong ?!!
|
|
|
|
|
Maybe the singleton's lease expired and the remoting framework created a new one?

I'm using this SQL SELECT statement:
int surveyNo
sqlTotal= string.Format("SELECT COUNT(survey{0}) FROM ResultsTbl WHERE survey{0}<>0", surveyNo);
I know the syntax is wrong in the parentheses after the COUNT. How do I fix this syntax, to put the variable value in?

First, you should be using parameterized queries to do this.
Your SQL statement should look like this:
SELECT COUNT survey FROM ResultsTbl WHERE survey = @surveyNum
The @surveyNum is a placeholder for a SQL parameter. More information can be found in this[^] article by Colin Angus Mackay.

I need to bring the column no. as parameter. The table has 4 columns: username, survey1, survey2, survey3. SrNo is an int variable the method get. I want to find out How do take this SrNo and "glue" it with survey
This is what I got from the article
sqlTotal= "SELECT COUNT(survey@SrNo) FROM ResultsTbl "+<br />
"WHERE survey@SrNo<>0";<br />
cmdTotal.Parameters.Add("0", survey@SrNo);
not to sue about survey@SrNo syntax. Got error in
cmdTotal.Parameters.Add("0", survey@SrNo);
under survey@SrNo.

Parameters don't work that way.
I don't know what your trying to return and I don't know what the conditions are. You need to explain how the data is setup in your table and what you want to accomplish.

Ans2 = int.Parse(cmdAns2.ExecuteScalar().ToString());
Ans3 = int.Parse(cmdAns3.ExecuteScalar().ToString());
cnSurvey.Close();
}
The data is table like:
username | survey1 | survey2 | survey3
-----------------------------------------------
sea# | 1 | 3 | 2
These are answers of a user to a survey. I need to collect all results from all users +total, so I can calculate statistics on it etc.
TIA,

I am able to find out the only one Lan connection(Ethernet Lan Card) (This setting is retrieved from the registry) and Modem connection is also showing on Winform.

I have a method in a class that updates an xml file based on an input parameter which is a DataTable.
To update my xml file I use the DataTable methods
<br />
GetChanges(DataRowState.Modified)<br />
GetChanges(DataRowState.Added)<br />
GetChanges(DataRowState.Deleted)<br />
The problem is that when I call GetChanges(DataRowState.Deleted) I do get a datatable of the rows that were deleted but all I can access is the number of rows but not the row contents so I can't figure out which rows were deleted.
Any help appreciated in advance.

The only way I could think of doing it is by having a method that when called to set a row color, the method loops through each item in that row and sets the color.
