This is my first program in c#. I got the logic, but lack with the features and code. Can u plz help me with the code Thank you for your response...

I want to create files with different names in c#. It should be in the form 0001.9001 0001.9002 0001.9003 0001.9004 0001.9005 0002.9001 0002.9002 0002.9003 0002.9004 0002.9005 0003.9001 0003.9002 .... 0009.9005 0010.9001 etc.... This much I could do. If the program creates a particular file name, when the program runs next time it should not create the same file name. Instead it should start the file creation as the continuation of the previous file name. Can I do it with any file operation.Please help me to find out the coding for this. Thank you for your time and support

We can browse and open the system files using OpenFileDialog Box.How can we open the selected file in a separate window?Can anyone direct me with the code for this, please.
