setforegroundwindow issue on a focus

[RobertLatherow]

I'm testing some code another coworker wrote, and it's bombing out in a very exotic way. Exception during remote setforegroundwindow - System.ComponentModel.Win32Exception: The system cannot find the file specified at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start() at BluePrism.ApplicationManager.clsLocalTargetApp.ForceForeground(IntPtr hwnd) I have had this error before on an 'Activate' action, and it was usually because I had only grabbed a portion of the W32 window and not the entire browser. I have no idea what to even look at on a Focus step. The element is a text input on the page, highlights fine, and is using AA attributes. At the point this fails, the action has already focused on 7 or 8 other fields with no issues. Anyone have any thoughts? -rj

Can anyone help on this? We are facing similar exception while trying to run a demo on someone else's system using Lync/Skype.

Setforeground window errors usually occur where the desktop does not exist - so the screen is locked or you are connecting to the resourcepc via RDP and disconnect. For global interactions (Activates, Global Clicks, Global sendkeys) to work the desktop needs to exist and not be locked. The VM technology that is used needs to provide persistance and consistancy (unlike RDP connections) - Please refer to the product documentation and reference guides.

Try recovering the exception on the business object page, wait 10 second, and then try once more. I've had previous experience where Activate would throw an exception for no obvious reason, and simply retrying would usually work. It's more of a workaround than a cure, but it might allow you to progress.

Apologies for dragging up a 2-month old thread but thanks to Jaya for that tip. I had exactly the same problem where BP was throwing up this exact error when it tried to close the save banner in Internet Explorer. Remarkably, just trying again nearly always fixed it.

Hi latherow, I am facing the same error shown below, ERROR: Internal : Failed to perform step 1 in Navigate Stage 'Activate the Main Application' on page 'Authentication' - Exception during remote setforegroundwindow - System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start() at BluePrism.ApplicationManager.clsLocalTargetApp.ForceForeground(IntPtr hwnd)   Could you please help me with the solution if you got any.

Lakshmi - the answers are already above in this thread.  Either your virtual desktop does not have a persistent visual screen, or you are using an application such as RDP to connect/disconnect (which our guides say not to use), or your virutalized environment has some kind of issue that might be fixed by having a retry loop that tries again after a few seconds.
