Look into optical character recognition and neural networks. OCR will allow you to extract the text, and the neural networks will allow your program to learn from its mistakes (and it will make them!). I think that there are components out there which automate this for your programs

how to prevent user created ports being restricted by antivirus software

1-Mar-09 21:43

Contact your rentacoder client. Tell them you are a liar and a fraud, and that you bid for jobs you have no idea how to do, then expect to get a detailed solution to a complex problem by asking in a public forum. I very much doubt the little you're being paid is enough to buy an OCR library.

1. Google for OCR.
2. Use a meaningful subject.
3. Poeple here help because they like to; they are not being paid for it. Please don't say your problem is urgent; it is considered rude.

Cheers,
Vıkram.

Carpe Diem.

in my application i create a socket with the port no 7575 which is a well known port. but the problem is i'm not sure if this will be blocked when an anti virus software installed. so what i want is to prevent this risk by setting the port not to be blocked in any anti virus software.means with out touching the anti virus software, need to do it only through my application.any idea ?

First of all, ports are blocked in general by firewalls. If the user is running Vista, you can use the COM interface of Windows Firewall to unblock a port. On the other hand, this unblocks the port for every application. Why not just use a different port (I use 65535, there's a list on the internet of the ports each application uses [an RFC I think] so you could also just choose one not on that list)

Hi i used the following code to run all the exe files listed in the list box control....listbox control contains a list of 10 exe files....
Now, if only 5 out of the 10 are currently running it should display a green colour otherwise a red colour....
How can i do this?

private void Start_Click(object sender, EventArgs e)
       {
           String n2,n1,n3,n4;
           n1 = lb4.Text;
           n2 = lb5.Text;
           n3 = lb6.Text;
           n4 = lb7.Text;
           if (cb.Checked)
           {
               n1 = lb4.Text;
              // System.Diagnostics.Process.Start(n1);
               proc = Process.Start(n1);
               proclist.Add(proc);

           }

           if (cb1.Checked)
           {
               n2 = lb5.Text;
               //System.Diagnostics.Process.Start(n2);
               proc = Process.Start(n2);
               proclist.Add(proc);

           }

         if (cb3.Checked)
           {
               n3 = lb6.Text;
               //System.Diagnostics.Process.Start(n2);
               proc = Process.Start(n3);
               proclist.Add(proc);

           }

           if (cb4.Checked)
           {
               n4 = lb7.Text;
               //System.Diagnostics.Process.Start(n2);
               proc = Process.Start(n4);
               proclist.Add(proc);

           }

 }

Re: Field Link in Datagrid

You'd have to iterate over open processes and work out if any come from this exe. You might also consider making your code a bit more readable, and perhaps even have it work with any number of listbox items. this is really ugly and messy

Field Link in Datagrid

Hi ,

I am developing a website with DATA GRID that displays the details of a student. When I click on the registration no of the student, a new page should open with the full details of the student(Datagrid only shows important details of the student).

Please discuss your ideas to achieve this.

Maybe you could use the HyperLinkColumn class. It could be the column where the registration numbers of the students are; bind the column text and hyperlinks to the same database where you draw the student data from. You can read more about this class here.

Its IndexOutOfRangeException and not Indexoutofrange, case sensitive

aratireddy wrote:

is because of,

aratireddy wrote:

{
Console.WriteLine(Exception.message);

Its Message and not message. Exception is a class in the .Net library, use some other name for the exception variable.
