I've been to the database and retrieved 1 or more values from a table that match with values for my ListBox text. eg
1 = John
2 = Peter
3 = Fred
etc
I have values say, 1 and 3 in a dataSet and can view each row
I want to get back to my page and have 1 or more names (John and Fred) highlighted. It's fine if there is one but multiple?
Code so far :
for (int i=0;i < dataSet.Tables[0].Rows.Count; i++)
{
mylistbox.SelectedValue = dataSet.Tables[0].Rows[i]
"PersonID"].ToString();
}
This only highlights Fred, the last row in my listbox on my page.
Any advice would be great.

You can create a ListItem and set its Selected property to true. Or iterate throught
ListItems in your ListBox.
Something like this:
int i = 0
foreach(ListItem li in ListBox1.Items)
{
if( (li.Value == dataSet.Tables[0].Rows[i]["PersonID"].ToString())
{
li.Selected = true;
}
i += 1;
}

Hi All,
I have a little problem...
From one form to another i am sending an array list.
ArrayList _line = new ArrayList();<br />
_line.Add(strNum);<br />
new frmCellNumberListCheck().Chekker(ref _line);
On the next form i have a list view. How do i populate the a list view with the values in my array list?
Here is the part on my next form...
public void Chekker(ref ArrayList _NewList)<br />
{<br />
_Confirmer = _NewList;<br />
this.ShowDialog();<br />
NewList = _Confirmer;<br />
}
Now in the load method of the form i want to use the _Confirmer to populate the listview called ChekkerList.
How do i go about doing so...
Thank you in advance
Nico

u can try
ListViewItem lst = new ListViewItem();
for(int i=0 ;i < _NewList.Count ;i++)
{
lst.subitems.add(_NewList[i].ToString());
}
CheckerList.items.add(lst);

Hello,
i am using a treeview so to assign different icons to different nodes i used a imagelist and assigning the imageindex and selected imageindex properties of the treenodes with the index of the imagelist icons collection. But for some nodes in the treeview that setting is not working its displaying the icon at the 0th index in the imagelist and whenever i display the index value associated with that node using a messagebox its giving "-1" value.
Why thats happening how can i get the icon which i assigned using imageindex and selectedindex to those nodes.
Please help me,
thanks in advance.

The way I read it you want to open a new Window..
form name: frmName
frmName frmName = new frmName();
frmName.Show();
If you didn't mean to open a form then I am misreading your post and am sorry

How to generate a random number.
I have Visual Studio 2003.
Help.

use the following code snippet:
Random rand=new Random();
and then u can use
rand.Next(1,100);
to generate a random no. between 1 & 100
Basically u have to specify the limits in which u want to generate a random no.
Hope this will work.

That will generate a random number between 1 and 99.

Thanx Guffa for correcting me

Thanks Guffa. This information helped me too. I was using the random generation in my program and was thinking the probability of generating last number could be less... but now came to know it does not generate. Intead it generates till one less(as in your example betwen 1-99) Thanks again!!!

The whole setup this implies is difficult at best (if you are just looking to have your program running in a certain language). It probably would be best to get a Multi-Language Windows-Release and install your program there, then choose your program's display language according to the language options currently selected in Windows.
However, I would roam the net and look for a language installation package, then add it as a script to your install-packet-creator.
Or, x-copy-installations, check if the computer has the language support and run the language installation if it does not.
Cheers,
Sebastian

This is my comparer:
public class movieIdCompareValueClass:IComparer
{
public int Compare(object a, object b)
{
return ((allInfo)a).movieId.CompareTo(((allInfo)b).movieId);
}
}
I am using it in:
found = Array.BinarySearch(outerContents, movieId, new movieIdCompareValueClass());
I have tried a couple different ways to set up the comparer, but I always get a runtime error on the above line:
System.InvalidOperationException
Additional information: Specified IComparer threw an exception.
What is causing this error? Is the comparer looking beyond the last element of the outerContents array? If so how do I prevent it?

It would be nice to know what exception the IComparer threw. It should be accessible through the InnerException property of the thrown InvalidOperationException.
If I have to guess, I'd say that you are getting an InvalidCastException. It seems your outerContents array contains allInfo objects as you're casting the objects a and b to it in your compare method. As object to search for you pass in something called movieId, so I guess it's a plain int or something similar which can't be cast to allInfo.

I may be off base, but at first thought, you are using a compare to complete a compare.
Try writing your own comparer long hand.
