Hello everybody.
If I well understood, until Ignition 7.x, the java libraries (JNA) was native from SUN.
But with Ignition 8.x the java lib are deployed by Inductive Automation with a custom package.
This shouldn’t a big issue but since now our previous scripts do not run anymore.
For a real example the following script now crashes at the first row:
**from com.sun.jna.platform.win32 import** *
**from com.sun.jna.platform.win32.WinDef import** *
def SendMessage(wndCaption, messageCode, wParam, lParam):
wPARAM = WPARAM(wParam)
lPARAM = LPARAM(lParam)
hWnd = User32.INSTANCE.**FindWindow**(None, wndCaption)
User32.INSTANCE.**PostMessage**(hWnd, messageCode, wPARAM, lPARAM)
if (None != hWnd):
User32.INSTANCE.**SetForegroundWindow**(hWnd)
def IsRunning(wndCaption):
hWnd = User32.INSTANCE.**FindWindow**(None, wndCaption)
if (None == hWnd):
return 0
else:
return 1
We need to get access to some Win32 API (FindWindow, PostMessage and so on) and we need to know how to do so with the new JNA distro.
Thanks in advance.
Best regards.
Stefano.
