I used WinDbg Preview and it worked !

@jacobson I know this is beyond LabVIEW, but I have the pdb file now and how do I attach to VS to find out which function it is calling ? I have narrowed down to this point. KERNELBASE.dll through .NET (0xE0434352) Unhandled exception at 0x00007FFF5FDC4008 (KERNELBASE.dll) in 33cb1333-6294-4505-a1fb-453e268d3b0b.dmp: 0xE0434352 (parameters: 0xFFFFFFFF80004005, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x00007FFF37DA0000). I want to find out this 0000022e3cccd80c3(). See attached screenshot. After opening the dump file with VS I selected the folder where the pdb file is from Tools->Option->Debugging->Symbols but it isn't displaying the function name. Thank you.

@jacobson That's very helpful! I will attach a debugger to find out. Thank you very much !

Hi Thank you!!! @jacobson Please see attached. 86cc2439-b4d5-448a-928e-3b3ce5e7e03a.dmp

From the debug report found in C:\Users\xxxx\Documents\LabVIEW Data\LVInternalReports\LabVIEW\17.0f2 (64-bit)\84ca9510-1bbf-48c1-b8ef-b46ed427d966\84ca9510-1bbf-48c1-b8ef-b46ed427d966 If I open the .dmp file with Visual Studio I get an exception unhandled message saying Unhandled exception at 0x00007FF873C54008 (KERNELBASE.dll) in 86cc2439-b4d5-448a-928e-3b3ce5e7e03a.dmp: 0xE0434352 (parameters: 0xFFFFFFFF80004005, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x00007FF84C320000). occurred This exception was thrown at the same address as the EIP #. Does that mean this exception was thrown at KERNELBASE.dll ? For lvlog.txt I have

Hi I have written an app to control my company's camera via a .NET wrapper. During live stream (LabVIEW isn't executing any command) LabVIEW crashes after an hour more. It is reproducible but the duration it takes to reproduce is inconsistent. I have attached Visual Studio's debugger and the memory usage was stable and at the time of exception nothing was caught on VS. The only information I have is the LabVIEW Crash Reporter's message. Every time when the crash happens the EIP is the same address. Given the EIP is there anything I can do to diagnose where the culprit is ? Thanks

I think I have figured out something by following this example code Event button.vi

Hi I have a simple program which has only 2 buttons for the user interface. When the user clicks OK I want the program to get into the event structure case called "OK Button". Once it is inside there is a loop which continuously waits for 1 second until "Stop Button" is called from the user. But because once the user presses the "OK Button" the program gets into the event and therefore I can not call the "Stop Button". Is there a way to call the "Stop Button" even if the program is inside the event ? Thanks event_out.vi

1. I don't have a "Timeout" and yes it does hang. 2. Yes That's exactly I want to do. Where do I create a while loop ? The end product is to display a histogram on LabVIEW in real time. The histogram library is written with .NET and my application reads the node from .NET, which keeps changing the histogram value and I want to iteratively read the value while the user is not blocked by it. That's why I will need an event structure for the user to press buttons.

Hi I am writing an application to update the numeric value given user's input value and depending on the user's input value the program checks if it is greater than 10 if it is greater than 10 then the program waits for 1 second and then will have a popup message says "true". My intention was to call the conditional check, printing true every one second if the user's input value is greater than 10; in other words, the case structure was to be called regardless of the event structure in the same loop infinitely. But it doesn't seem to work the way I expected. Unless there is user's new input value, getting into the event structure, the program doesn't get to the case structure even though the case structure is in a loop. Is there any way to call the case structure not dependent to the event structure but I want to use a shift register for the numerical value and also having an event structure and a case structure in parallel ? Thank you. test.vi
