i have used this.
List<string> strTemp=new List<string>;();
how can i achieve the same in HashTable, like
HashTable<string,int> strTemp=new HashTable<string,int>();

Try Dictionary.
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 alpha 4a out now (29 May 2008) ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

Inherit HasTable Class and Create Your Own Class with Add and Get Methods
And Check For the Values in Custom Methods.

.NET 2 introduced the Dictionary generic, so this would be achieved using:
Dictionary<string,int> strTemp=new Dictionary<string,int>(); The only thing to watch out for is how to access it. In order to iterate over the Dictionary, you use the KeyValuePair generic, so you would end up with something like this:
foreach (KeyValuePair<string,int> item in strTemp)
{
}
|
|
|
|
|
The generic version of the HashTable is the Dictionary:
Dictionary<string, int> temp = new Dictionary<string, int>();

Hi,
What is the reason for the StackOverFlowException and AccessViolationException
and the solutions for these errors in windows application + C#.net 2.0
|
|
|
|
|
They're pretty self explanatory, but here goes.
tauras81 wrote: StackOverFlowException
This occurs when the stack overflows. There is a limited number of methods that can be called, so the most common occurance of this exception is when you keep calling the same method over and over again. The most common time i see this exception is when I make a case-related typo eg
public class Foo
{
private int bar;
public int Bar
{
get{ return this.Bar; } <-- that should have said this.bar. By being uppercase it will keep calling itself. StackOverflowException will occur
}
}
tauras81 wrote: AccessViolationException
This exception is usually thrown when trying to read or write protected memory. It has to do with unsafe or unmanaged code, and as I dont deal with this very often I cant think of a simple reproducable bit of code to demonstrate it. You could try the documentation[^] - a good place to go in both these cases.

This error occurs when
--- We have called any function or Property from Itself
When we are calling function it saves current function's state in Stack Memory
But when we call recursively(infinite) then it results in overflow of memory.

hi there!! I have an issue with the PrintPageEventHandler function. There are two parameters what are coming with the function(object and PrintPageEventArgs), I want to add one more parameter, XmlDocument, but when I am trying to do that, I am receiving an error: No overload for PrintPageEventHandler matches delegate "System.Drawing.Printing.PrintPageEventHandler". Is there anyway how I can put some other parameter for this handler or no? Thx ahead

Good morning good cpians
DataTable dt = new DataTable("SomeTable");
string[] tokens;
dt.Columns.Add("ID",typeof(int));
dt.Columns.Add("Name",typeof(string));
StreamReader sr = new StreamReader("C:\\SomeFile.csv");
while (!sr.EndOfStream)
{
tokens = sr.ReadLine().Split(',');
if (tokens.Length == 2)
dt.Rows.Add(tokens);
string strExpression = "ID = 1";
DataRow[] dr = dt.Select(strExpression);
MessageBox.Show(dr[0].ToString());
I've been posting this since yesterday and I still need it to be as I wrote it "DataTable is filled out of a file that makes it ambiguous to decide what type the value is" as seen from my example, can you please try it with my exact code and tell me what modification I would need?? Cuz I think the problem is in the way I'm storing data not in filtering it!
ps. I should also be able to apply other operands like < and > and concatenate them with variable values.
Many thanks guys!

Thanks I've done it the other way round
double d_ID = Convert.ToDouble(MyDataRow["ID"].ToString().Trim())
if (d_ID == 0)
MessageBox.Show(d_ID.ToString());
But still interested to know the answer for more complex select statements
Thanks!

You need to add reference to System.Configuration
|
|
|
|

Another error :Configuration system failed to initialize.
Please help.

And that means you are in the wrong place. Head off to the ASP.NET forum.

Use the <> operator.
