Re: How to refresh Treeview control - C# Discussion Boards

5-Feb-09 0:28

Hi,
In my treeview control, I changed the indexes of the nodes. While debugging, I found indexes of the nodes are changed successfully. But the changes were not reflecting in the UI.
Please let me know how to refresh the treeview.
Thanks in advance..

have you tried:

treeview.Refresh();

or

treview.Invalidate();

My opinion is... If someone has already posted an answer, dont post the SAME answer

ya, I tried both. They are not working..
I tried treeview.Update(), but in vain..

musefan5-Feb-09 0:42

are the nodes you change at the same level in the tree view.

I have not tried changing the index before i can only think that maybe the index does not represent what you think it means? or maybe is there anything set that auto sorts the nodes? like aplhabetically or something?

My opinion is... If someone has already posted an answer, dont post the SAME answer

AFAIK you cant change index of any node, its readonly property(Index). It would be better if you explain how did you change the indexes...

I used the following code to change the indexes.

TreeNode Node0 = treeView2.Nodes[i - 1];
TreeNode Node1 = treeView2.Nodes[i];
foreach (TreeNode node in treeView1.Nodes[0].Nodes)
{
if (Node1.Text == node.Text)
{
m = node.Index;
}
if (Node0.Text == node.Text)
{
n = node.Index;
}
}
if (m < n)
{
tempNode = Node1;
Node1 = Node0;
Node0 = tempNode;
}

Are you using Remove and Insert to move the node?

(I've never tried it, but suppose it should work.)

Hello friends,

Can u help me to delay the second instance of application.??

I want my application must be multi instance appliation but if double clicking immediatly second instance should start after some specified delay!!

Thanks in advance

Just search for code to do a single instance app, and instead of closing the second instance, have it wait a while before starting. The only hard part then is working out how long ago the last instance was run so you know if yuo need to wait.

Presumably when a new instance starts, rather than creating a lock, it creates a lock with a timer that auto frees itself after X seconds.

The second instance would wait till the first instance unlocks, and so on.

hmmm... not quite sure what you mean. But maybe the first thing your app does is to check if another instance is running (maybe with a loop through processes or something), if it finds an instacne, then insert a delay before moving on

Have i misunderstood your requirements?

EDIT: I didnt think of the checking how long first app been running as suggested in previous post. Why do you need the delay for anyway? just out of interest

Hi,

webservices are base on SOAP. This protocol uses XML to exchange data. The message is saying that during the serialization of request/response the corresponding XML could not be created. Maybe you should post the client call and the corresponding service method? One of your objects you are passing could be the cause.

NumTrans
There is an integer K. You are allowed to add to K any of its divisors not equal to 1
and K. The same operation can be applied to the resulting number and so on. Notice that
starting from the number 4, we can reach any composite number by applying several such
operations. For example, the number 24 can be reached starting from 4 using 5
operations: 4->6->8->12->18->24
You will solve a more general problem. Given integers N and M, return the minimal
number of the described operations necessary to transform N into M. Return -1 if M can't
be obtained from N.
Definition
Method signature: int GetLeastCount (int N, int M)
Constraints
- N will be between 4 and 100000, inclusive.
- M will be between N and 100000, inclusive.
Examples
1) 4
576
Returns: 14
The shortest order of operations is:
4->6->8->12->18->27->36->54->81->108->162->243->324->432->576
2) 8748
83462
Returns: 10
The shortest order of operations is:
8748->13122->19683->26244->39366->59049->78732->83106->83448->83460->83462
3) 4
99991
Returns: -1
The number 99991 can't be obtained because it’s prime!
