I have a treeview where I add nodes. Before I add a new node to the treeview I want to check if a node with the same name allready exist, how can I do that in an easy way ?

if (!treeview1.Nodes.Contains(nodetoadd))<br />
{<br />
//treeview1 doesn't contain nodetoadd<br />
}<br />
else<br />
{<br />
//treeview1 contains node nodetoadd<br />

That would not work, consider

<br />
 TreeNode tn1 = new TreeNode("item1");<br />
 TreeNode tn2 = new TreeNode("item1");<br />
 treeView1.Nodes.Add(tn1);<br />
 if(!treeView1.Nodes.Contains(tn2)){<br />
     treeView1.Nodes.Add(tn2);<br />
  }else{<br />
    // dont add node<br />
  }<br />

treenode tn2 has the text as tn1, but it is not THE same treenode.
but you could use the Name property and ContainsKey method

<br />
 TreeNode tn1 = new TreeNode("item1");<br />
            tn1.Name = "item1";<br />
<br />
            TreeNode tn2 = new TreeNode("item1");<br />
            tn2.Name ="item1";<br />
            treeView1.Nodes.Add(tn1);<br />
        <br />
            if(!treeView1.Nodes.ContainsKey(tn2.Name )){<br />
                treeView1.Nodes.Add(tn2);<br />
            }else{<br />
                MessageBox.Show("node exists"); <br />
            }<br />
<br />

If it' stuck, DO NOT pull harder!

String.Format question

Is it possible to use two or more kinds of format for String.Format()?
For example, If I want to display the 1.452677e-12 as 1.45e-12, how to do?

thanks

Sure, why not... There are many ways to do that.

simplest way...
string result = String.Format();
result = String.Format();

depending on the formatting you are doing, you could also do
.ToString().ToString() and use the standard IFormatProviders.

Sorry - The mm should be MM. So this would be Label2.Text=DateTime.Now.ToString("dd/MM/yy");

No, always use ISO 8601 compliant formats like "yyyy-MM-dd".

Don't expect solutions without clear explanation of the situation and the error.
What DB do you use?
How do you access the DB?
How many users ?
Do you handle and log exceptions?

well every line of code is in try and catch block,the application was running fine before updating the windows server 2003,but after updating the windows it's creating problems like hang and gets close during running..before throwing any exception or with out writing any thing in the logs..!!!!

Maybe you should use profiler and look at performance counters, locks.
Make sure that you have the latest service packs installed.

If you are using a stored procedure with a SqlDbType.DateTime parameter in it then you can directly assign your DateTime variable into the parameter. You are using parameters aren't you?

Where System.Int32 will be stored?

J a a n s2-Nov-07 0:52

2-Nov-07 0:52

Till now I was thinking that as System.Int32 is Valuetype, it will be stored in stack. But while profiling the application I have seen instances of System.Int32 in the heap.
Can anyone give a little clarification on this?

Thanks

Here's the confusing thing - value types are always placed where they are declared. If they are declared within a method, they will always appear on the stack. If it's declared outside a method, but inside a reference type, it will be placed within the reference type (on the heap).

Confusing huh?
