Ok but with polling the client would have to make queries every 2 or 3 seconds to get close to real time
If it's not broken, fix it until it is

Yes, only as frequently as the user wants.

Language? C#
ASP.Net is not a language. It's a Web Development platform

Can you narrow down where the specific issue is?
There are only 10 types of people in the world, those who understand binary and those who don't.

I think the problem is here:
if (searchResult.Properties.Contains("thumbnailPhoto"))
{
dr["thumbnailPhoto"] = byteArrayToImage((byte[])searchResult.Properties["thumbnailPhoto"][0]);
}
Or maybe in the asp code.
At the moment I get a table with every field populated how it is intended to be however the thumbnailPhoto field display a image of an X as though it isn't being pulled through.
If I run the command Response.BinaryWrite(staffPic); it displays the image on a complete blank screen.
What I'm trying to do is pull through the thumbnailPhoto pic into the datatable and then onto the gridview

Hi everybody,
On my Windows Mobile 6.5 application (developped in C# and DOTNET 3.5), I want use a VPN connection. My goals is the following: I connect my PDA on my PC via USB. Then, by clicking on a button of my WinCE application, I would send http request (with the object "HttpWebRequest" of C#) directly on PC (because VPN would be intalled on the PC).
I have already searched a solution of my problem but I have not found a solution.
Have you got an idea to do this?
Best regards

Google for instructions on how to set up VPN.

..if you're trying to talk to the server-VPN using TCP/IP from the mobile device, then that's not going to work. Try talking to a webserver on the PC.

If you can't read my code, try converting it here[^]

i think you should write another application for your PC also which will receive requests from your windows phone and talk with VPN connection in pc and again send results to your phone but talking directly with windows phone is not a good and practical approach!

|
|
That could also be considered as opening a security hole in the VPN!

I am trying to move items up and down in generic list but not getting desired results If I have 5 items and and one their be 6 with order id's of 1 to 6 then when i move an item up one position via button click say item 6 it would become 5 and what was at 5 would become 6.
Can Someone help me out here please on the logic below?
ObservableCollection<CustomColumnsModel> columnsList = this.WizardData.ConcreteCustomColumnsProxy;
Extensions.MoveItemUp(columnsList, this.listView1.SelectedIndex);
List<CustomColumnsModel> forUpdate = new List<CustomColumnsModel>();
int offset = 0;
foreach (CustomColumnsModel item in this.listView1.Items)
{
if (this.listView1.SelectedItems.Contains(item))
{
offset++;
item.CustomColumnsOrder--;
}else
item.CustomColumnsOrder += offset;
}

Not true, this is a perfectly valid question for this forum.

My point is that in order to get more answers it might be better to post it in the quick answers section.
Just look at the number of responses during almost 24 hours.

That's hardly a reason to repost it.

Given a List of Integers:
List<int> positions = new List<int>{1,2,3,4,5};
How would I code a loop to get the following results for a given number of iterations {n}:
n P1 P2
1 1 5
2 2 1
3 3 2
4 4 3
5 5 4
6 1 5
7 2 1
8 3 2
9 4 3
10 5 4
...
This should be simple but I have brain freeze.

p1 almost looks like n mod 5 + (5 iif prev result is 0)
p2 almost looks like p1 - 1 + (5 iif prev result is 0)
'g'

|
|
|
|
List<int> positions = new List<int> { 1, 2, 3, 4, 5 };
for (int n = 1, p1 = 0, p2 = 4; n <= 10; ++n, ++p1, ++p2)
{
p1 %= positions.Count;
p2 %= positions.Count;
Console.WriteLine("{0,2} {1} {2}", n, positions[p1], positions[p2]);
}

That works well and creates the list for n iterations.
How about finding the value of p1 and p2 when n is a defined number?
int n = 23;
p1 = ?
p2 = ?

If n starts with 1, then
p1 = (n-1) % positions.Count;
p2 = (positions.Count + n - 2) % positions.Count;
