which application put data into clipboard

[johnsheares]

Is there a way to find out which application put data into the clipboard. I want my app to respond only when data was put into the clipboard from a specific application. The clipboard notifier code that I am using

I figured it out after doing some more research. Here is the code that I put in the clipboard change event.


IntPtr ownerHwnd = GetClipboardOwner();

uint processId;
GetWindowThreadProcessId(ownerHwnd, out processId);
Process process = Process.GetProcessById((int)processId);
Debug.WriteLine(String.Format("Owner: {0}, processid: {1} Title: {2} Exe: {3}", ownerHwnd.ToString("X8"), processId, process.MainWindowTitle, process.MainModule.FileName));


One thing that I have noticed is that I can't always get the window title. Apps like Internet Explorer and file explorer don't return a title.

Is the application that puts data on the clipboard your own?
If so, have it add a custom datatype to the clipboard as well as the other data that you can trigger off of?

Nope, it could be any application that puts any type of data into the clipboard. My solution is back a few posts. This is how it works:

In the configuration of section of my program, I have a property that stores the application being monitored, which is the exe filename. When I get a clipboard content changed notification, I find the processid from the owner handle that last put data into the clipboard using GetClipboardOwner and then GetWindowThreadProcessId. With the processid, I can get the Process using Process.GetProcessById. From there, I can get various properties including the filename, which is compared against the one that I configured to be monitored. If they match, the clipboard data is processed.
