Hi Guys.....

I need help , I want to know Process Name which is using a file.

Ex. I want to know file ABC.txt is opened by which Process.

Actually i want this because, I am doing Continuous Printing , the steps I am doing is following

STEP1 : Checking If Rich1.txt Exist or not if Yes, then I am deleting it first , then Creating new txt with Name Rich1.txt

Step 2: Now writing characters using streamwriter. After writing Characters i am closing Closing streamwriter

Step3 After writing Rich1.txt Sending it to RawPrinter(Printer)

But the Real Problem is that when i Do continuous Printing (One after One)
then first time it is Printing ok , But when it comes for second time
then it is throwing exception at step1 that C:\Rich1.txt is used by another Process

I am unable to konow which process is using it . I look in Taskmanager for notepad.exe ( because .txt is opened by notepad ) but i not got.

Any Help is Welcome.....!

The chances are it is in use by your own application.
First thing to do is to use Dispose on any and all streams in your app - Close may not be sufficient.
Secondly, if that doesn't fix it, then there is a very good chance that the RawPrinter has the file open until it is completely finished with the print out.

Try this: Remove the RawPrinter stuff from your code for testing - does the problem still persists? If it doesn't, then you know where the problem is - you will have to wait until the print is complete somehow.

"Remove the RawPrinter stuff from your code for testing" - the last two words are important! :laugh:
The idea is to find out what is causing the problem. If you can't do that, you can't guarantee to have fixed it...

I solve it Problem by using two textDocument For Ex. Rich1.txt and Rich2.txt and

When i checked for File Rich1.txt if it exist ? here, it is giving exception . I put this code in try Catch and when Control goes to Catch Line then I start writing Rich2.txt
and Send it to Printer.
