Here is some code from what I've tried: bool IsResponding(Process process) I am amazed I haven't been able to find relevant resources related to my issue. So this method to determine if app is not responding is also INVALID after the application crashes (JIT debugger popup reports app crashed and displayed "Not Responding" in task manager) all the above messages sent to the process window handler return 1. before the application crashes: reports running ( all messages return 1) *I used the SMTO_ABORTIFHUNG, SMTO_BLOCK, SMTO_NORMAL, SMTO_NOTIMEOUTIFNOTHUNG and SMTO_ERRORONEXIT So the problem is : task manager shows not responding, Process property responding = True, this method to determine if an app is not responding is INVALIDĢ Sending timeout messages to the main window handler. I found a lot of open source task managers (top 5) and all use the "Responding" property to determine if a application is running. At this particular moment Task Manager reports the app "Not responding" but the process information (although it does have a main window handle ) has the property Responding set to "true". The problem is, when an app stops working (crashes) the process is still running, the JIT Debugger message pops and reports the app crashed. Since I am not creating those applications and I do not have access to modify them in any way I can only rely on the information provided by windows.įor the past week I've been trying to find exactly how to get the "not responding" property as shown in task manager for an application.ġ Using system diagnostics, getting the process information and interpreting the information within.
I am using visual studio and a windows environment that supports. I need to develop a watchdog app that needs to keep various applications running.
