I have attached a VI(Saved in LV 7.0) in this topic.

This attachment code can help you capture and paste screen image on front panel.

Holp this can help you..

You can use the Invoke note to get the control/indicator image, also the whole front panel img if you want.

I attach a VI that I use to programmatically update the snapshot of

a computer's desktop in a webpage :camera:

To run this VI you need the http://forums.ni.com/attachments/ni/170/157084/1/Clipbrd.zip' target="_blank">clipbrd.llb library.

The VI uses a call to Win32 API function "keybd_event" in user32.dll,

therefore it only works under Win32.

The "invoke node" method suggested before should be platform independent

but does not provide the entire screen.

Note:

the enumerator used to select the "print screen" key includes many other

(probably all) possible values to call the "keybd_event" function

(I found it somewhere but I don't remember where,

I apologize with the author for the lack of credits :worship: )

I use LV 8.2 and I can down-convert the file only to 8.0.

I hope you can find a way to convert it down to LV 7.0

Have fun :beer:
