I have a class that I call Runner. It starts the required process, and then starts a background worker object that serves to allow the programmer to terminate the process. When the process terminates (either normally or by user-intervention, it fires a custom event and the calling form handles the event.

Using a class like this, you could disable the button when the process is started, and re-enable it when the process terminates. Alternatively, you could leave the button enabled and check to see if a globally-defined runner object is != null to see if you should display a message to the user or not.

I originally wrote this code so that I could track how much time was spent running the spawned process.

Thanks for the comment.

Ya, that's the way I'm normally working on. But the thing here is I cannot disable the button. As I said in earlier post, in that click event I have to start two process.

I appreciate your help all the time...

Hello, Here is the code

private void button3_Click(object sender, EventArgs e)
{
button3.Enabled = false; Process proc = new Process(); proc.StartInfo.FileName = "notepad.exe"; proc.EnableRaisingEvents = true; proc.Exited += new EventHandler(proc_Exited); proc.Start();
}
void proc_Exited(object sender, EventArgs e)
{

myDelgate d = new myDelgate(enableBtn);
this.Invoke(d);
}
void enableBtn()
{
button3.Enabled = true;
}

Remember u should add the statement

public delegate void myDelgate();

inside the class which declare a delegate

I hav sucessfully disable the button on starting notepad and enable afte exiting the notepad

hope this code will help you.

Get each section of the address seperately from user and use string.Format(...) to do your thing.

What do you mean by "address"? Do you mean a postal-location, or a mailaddress or something?

In which case it all depends on the country - there are multiple different formats for addresses. Pick one you like and use it Smile | :)

this is the standard address....

no : 5,abc building,xx street,yy city,country

but the user may give any in any order...my program should standadize it in the above format

abc building,no : 5,xx street,country,yy city

this is the input from the user

Local yes, but other countries may use different formats.

One idea for you to think about:

if you have an address for example that consists of 4 data fields i.e

Street
City
Country
Postcode

you can assigned each value an index like

street = 0, city = 1, country = 2, postcode = 3

then you ask the user for there preffered order;

maybe they put street(0), city(1), postcode(3), country(2)

then when you load your address data which should always be stored in a standardised format you can load it in the order required based on the index values.

Sorry if this is not making to much sense, its a hard one to explain

do you get the idea?

an example:

string[] loadedAddress = {"Street", "City", "Country", "Postcode"};//values loaded from datasource
int[] userFormat = {0, 1, 3, 2};//order format specified by the user

for(int i = 0; i < userFormat.length; i++)
{
    textbox1.text += loadedAddress[userFormat[i]] + "\n";//writes each address line to a textbox line
}

There is no "standard" for postal addresses, or the postal service would use it. The postal-service will not comply to the standards that we design, so we (as developers) have to ensure that we can use any address (in any format) as provided.

E.g., there are three different formats of "normal" addresses in Holland. We got the usual street-zipcode combination, we got Postboxes for companies and we got Answeringnumbers - a sort of Postbox for a company, but without the need to stamp the damn thing.

The first one, street-zipcode combination, uses a number for the house. That's the most common way, I guess. Alas, Curacao has some streets where there aren't any numbers on the house - the postal-worker has to verify the address by reading the addressed family-name.

Unless you're going to use the address-details in computations/measurements/analysis, I'd suggest you be liberate in what you accept.

actually its an artificial intelligence system.....

TRAIN HMM is a software used to train the standard address format and save the probability in a log file... from which it'll be useful to standardize using viterbi algorithm(source:wikipedia)

So you're going to develop something that can verify whether something 'could be' an address? Sounds cool and complex!

Good luck Smile | :)
