Copy and paste data between 2 notepads in C#

Copy and paste data between 2 notepads in C#

  I need to prevent users from pasting the text

  Hi,

  I wrote some code snippet which copies text from Clipboard and pastes to notepad.

  I have used WM_SETTEXT to paste the text into the Notepad. The same way you can get the text from notepad using WM_GETTEXT.

  Please refer the sample and modify it as per your need if possible.

  Look at the last post of mine at http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1108725&SiteID=1

  For more info about WM_XXXTEXT please refer,

  HTH,

  Can't you just copy the stuff with C# code instead of using the windows Copy/Paste funcitionality

  It's not clear what you want... do you want to copy/paste between notepad, or do you want to PREVENT users from doing it

  I posted how to handle the pasting in this post:

  If you open the notepad.exe programaticaly. You could just open 2 multiline textbox and handle the copy/paste yourself (much easier). Sort of creating your own notepad that prevent paste.

  You cannot stop people from opening notepad themself and modifing the text and if you do find a way to prevent copy/paste when the user open notepad by himself then that's not a feature I would like to have installed in my computer.

  This sounds very tricky. The only thing I can think of is writing a hook with the win32 API and intercept the WM_PASTE message to the second notepad. This is a lot of work and needs some good understanding of the internals of windows. Why are you trying to accomplish this

  Start looking in the System.IO namespace for file handling.

  I'm working in an e-publishing concern. Here we process a lot of 3b2 files. When we start a 3B2 application, scripts are generated. These scripts generate data.

  This data is copied from one file to another file. But the data should be unique for each file. Since people are copying and pasting this data, we encounter certain problems.

  So to overcome this problem, we need to find a solution.

  Can u suggest some other solution for this problem

  Thanks!
