I think you are asking:
"In Asyn Callback if some error happens and it enters into a infinite loop then will all other calls will be hanged or will these requests be processed?".
I beleve the answer is that they will hang.

Hi As per ur believe it will hang and it is really so. So now how can i achieve this. Say in ATM a user comes and checks his balance now if there is some error in server them it is particular for that request all other users are not affected.

My requirement is same the if a asyn call enters into infinite loop it should be for that call only not for all the subsequent request.

thanks in advance

Create a Thread for each incoming connection, you may want to use a ThreadPool for this. But see my answer above, don't let your app fall into a infinite loop at all!

Hello

This depends on the library -if any- you are using. No classes in C# deals directly with pdf files.

You won't find examples for "writing pdf with passsword protection" straightforward. Searching for that won't get you anywhere. What you are looking for is a pdf writing library. Some commercial libraries are out there. As I told you, search CodeProject's articles areas for "pdf", or google for "pdf C# library". That might get you closer.

PS.
Elcomsoft has a program called Advanced PDF password recovery by the way. So, if your documents isn't that value, don't make the effort. Good luck!

Splitting an ArrayList

28-Sep-06 2:39

Hi,

I have an ArrayList which was populated by a text file with no column headers. What I want to do is split the ArrayList into columns then display it in a datagrid. The ArrayList is made up of lines such as

0168EH1X.PA0 020 1 GRA_ 08/14/06 12:16:42

I need to split this into 5 columns under the headings ID, Duration, Status, Channel and DateTime.

I've been trying to do this with the .SubString method but no luck. I know how to define the columns in the grid but I can't split the ArrayList up. Please can anyone help?

Thanks

Scott

Hi,

Yes, it is. Anywhere between 10 and 150 strings. The format for each string is identical.

Simple! use

MyArrayList[X].ToString().Split(' ');

to get an array of strings of each column.

I think that the 'e' must be sticking on your keyboard.

I needed to do this recently myself and rather radically I did a search for it on Google.

To save you spending valuable seconds doing the same, here is the url that I found.

Use the & symbol before the letter you miss to be used

&File = Alt+F
E&xit = Alt+x

Hello

1- Call CreateFile() and supply it with the name of the port
2- make a FileStream object and give the constructor the handle returned from the above call
3- Use the stream to read/write data from the port.

You could just start the command line compiler of java (System.Diagnostics.Process.Start(...) and check if the appropriate .class file has been generated in the file system.

Hi,

Just execute the command from your c# programme to compile the java code and check the output of that,from that determine the success of that,you also dont need to check for the .class file for the perticular .java ,either way you can do that.

Cool | :cool:

1.TO make a ref of progressBar
2.to make a variable global that is accessible in both window application and class library
3.During a thread that is in class library and start at ButtonClick event
how can we check the variable of thread at control event during the thread execution.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
