I'm trying to setup Drwtsn32.exe as the crash handler on a windows xp embedded system. I have run drwtsn32.exe -i from the prompt to install it as the default handler. Then I added a couple different fragments that would cause exceptions into our application as a test:
int y = 0;
int j = 0;
j /= y;
int* p = 0;
(*p) = 0;
When I run our application for the first time, I get a Drwtsn32.exe popup correctly, the application closes, and drwtsn32.log is written and shows my crash. When I run the same application again, I get no popup, and no log is written. This repeats until I reboot, when the popup and log are both generated a single time, then the problem persists.
On a different system, I see different functionality - drwtsn32.exe does not generate an error (although I do see the MS Send Report popup) and the log is generated every single time, without requiring a reboot.
Does anyone know if I am missing a configuration option, or if a component is missing in our Windows XP Embedded Image?
Thanks

I'm in a project in which I have to run an Anylogic simulator multiple times. I made an script to modify the input data, run the simulator and then store the output data just before the next simulation run.
The idea is to externally run the simulation (from a python file). The problem is that, when the simulation ends, the simulation window doesn't close automatically so the python file won't continue executing.
I´ve tried to run the simulator without showing the animation of the simulation but still opens a window so it doesn´t work for my purpose.
I don´t know if there is an option in Anylogic to export a model that automatically closes the window once the simulation is completed or if there is any way of creating a simulator that runs without opening any window.
Thank you.
Unfortunately there is no such solution. Even if you can run without UI in Linux, it will not automatically close once the run is complete. I use a workaround:
It is a Python script that scans the outputs folder every 5 seconds and if there are changes in the files, it closes the AnyLogic file. Use this as an inspiration::
from time import sleep
from utils.data.fileSystem import FileSystem
def sync_polling_folder(path, predicate, delay_sec):
print('checking under ' + path + ' folder')
beginning = FileSystem.stat(path)
old = beginning
new = beginning
def two_files_are_different():
return not predicate(str(old), str(new))
def the_process_has_not_begun():
return str(new) == str(beginning) or str(old) == str(beginning)
# if two folders are the same, quit (means no-changes = finished)
# but if they are equal because process never started, keep going
while two_files_are_different() or the_process_has_not_begun():
print('[sleeping] because files are not written yet.')
sleep(delay_sec) # main thread waiting
old = new
new = FileSystem.stat(path)
print('[anylogic] ready to be killed')
return True
I'm trying to create a Selenium script in Powershell that automatically buys something that I tell it to. I've gotten it past finding the item, and clicking the Buy Now button, but then this window pops up and I've tried what seems like 3000 different ways of failing to click the Place your order button. Web code to the right. Appears to be the "turbo-checkout-pyo-button", but finding it by ID, XPath, CSSselector, etc have all failed for me. It's not a wait issue. I've even thrown in an explicit (and overly long) 5 second delay to be sure this field is present and "should" be clickable. Any ideas?
I've tried all of these. They're all followed by $placeYourOrderBtn.click() (and have all failed):
$placeYourOrderBtn = $ChromeDriver.FindElementByXpath("//*[#id='turbo-checkout-pyo-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//*[#id='turbo-checkout-place-order-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//span[text() = Place your order]")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-place-order-button-announce")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-pyo-button")
$placeYourOrderBtn = $ChromeDriver.FindElementByCssSelector("#turbo-checkout-pyo-button")
I did this for a windows that sends email. You have to click the button to open the new window, then use "SwitchTo()" to change to the new window.
[void]$Webdriver.SwitchTo().Window($WebDriver.WindowHandles[1])
You may have to read the window handles attribute and query each one to determine which one you need to open.
This Problem occurs on the RPi (3B+, Raspbian Buster) only. I run the program on my Mac without any problems.
Short description of my program:
After entering the mainloop, the program enters a second thread with another loop (call it requestloop) when the designated button is pressed. The requestloop can be left by pressing the button again. This requestloop requests a xml table via url every 10 seconds which is then parsed with ElementTree, sorted and displayed in a wx.grid.Grid. I use grid.ForceRefresh to make sure the grid is updated.
I hope the following snippet helps to understand the above:
def on_btnrun(self, event):
global run
if self.btnrun.Label == "Start":
run = True
thrupt = threading.Thread(target=self.thrupdate)
thrupt.start()
self.btnrun.SetLabel("Ende")
elif self.btnrun.Label == "Ende":
run = False
self.btnrun.SetLabel("Start")
def thrupdate(self):
while run is True:
reset()
self.grid.ClearGrid()
update(self.grid)
self.grid.ForceRefresh()
time.sleep(10)
Problem:
Now as mentioned in the title the whole wx Window freezes after passing the requestloop between roughly 5 and 20 times. This happens completely randomly, I could not find any regularities. The program keeps running though, for it still prints the output in the terminal every cycle (I added this function for testing).
When I now open another window (eg. menu dropwdown) which lays over the wx Window it will be copied onto the wx Window and stay there after I closed it.
Here are some Images to better understand what I mean (ignore all other widgets that I didn't mention, they are just nonfunctional placeholders).
Image of the wx Window before it freezes
Image of the wx Window after it freezes
Image of the wx Window after opening and closing the dropdown menu
Extra-Info: while building wxPython on the RPi I got some warnings and everytime I run the program I get the following one (it says the actual time instead of time):
(program.py:1666): Gtk-Critical **: time: gtk_distribute_natural_allocation: assertion ‚extra_space >= 0‘ failed
Question:
I have no idea why any of this happens. Is wxPython not stable on Raspbian? Or did the build partly fail? Or is the RPi not having enough rendering capacity?
Solved it by using wx.CallAfter in the details of the update() method.
I working on updating a Typo3 7.6 to 8.7. I do this on my local machine with XAMPP on windows with PHP 7.2.
I got the backend working. It needed some manual work in the DB, like changing the CType in tt_content for my own content elements as well as filling the colPos.
However when I call the page on the frontend all I get is a timeout:
Fatal error: Maximum execution time of 60 seconds exceeded in
C:\xampp\htdocs\typo3_src-8.7.19\vendor\doctrine\dbal\lib\Doctrine\DBAL\Driver\Mysqli\MysqliStatement.php on line 92
(this does not change if I set max_execution_time to 300)
Edit: I added an echo just before line 92 in the above file, this is the function:
public function __construct(\mysqli $conn, $prepareString)
{
$this->_conn = $conn;
echo $prepareString."<br />";
$this->_stmt = $conn->prepare($prepareString);
if (false === $this->_stmt) {
throw new MysqliException($this->_conn->error, $this->_conn->sqlstate, $this->_conn->errno);
}
$paramCount = $this->_stmt->param_count;
if (0 < $paramCount) {
$this->types = str_repeat('s', $paramCount);
$this->_bindedValues = array_fill(1, $paramCount, null);
}
}
What I get is the following statement 1000 of times, always exactly the same:
`SELECT `tx_fed_page_controller_action_sub`, `t3ver_oid`, `pid`, `uid` FROM `pages` WHERE (uid = 0) AND ((`pages`.`deleted` = 0) AND (`pages`.`hidden` = 0) AND (`pages`.`starttime` <= 1540305000) AND ((`pages`.`endtime` = 0) OR (`pages`.`endtime` > 1540305000)))`
Note: I don't have any entry in pages with uid=0. So I am really not sure what this is good for. Does there need to be a page with uid=0?
I enabled logging slow query in mysql, but don't get anything logged with it. I don't get any aditional PHP error nor do I get a log entry in typo3.
So right now I am a bit stuck and don't know how to proceed.
I enabled general logging for mysql and when I call a page on frontent I get this SQL query executed over and over again:
SELECT `tx_fed_page_controller_action_sub`, `t3ver_oid`, `pid`, `uid` FROM `pages` WHERE (uid = 0) AND ((`pages`.`deleted` = 0) AND (`pages`.`hidden` = 0) AND (`pages`.`starttime` <= 1540302600) AND ((`pages`.`endtime` = 0) OR (`pages`.`endtime` > 1540302600)))
executing this query manually gives back an empty result (I don't have any entry in pages with uid=0). I don't know if that means anything..
What options do I have? How can I find whats missing / where the error is?
First: give your PHP more time to run.
in the php.ini configuration increase the max execution time to 240 seconds.
be aware that for TYPO3 in production mode 240 seconds are recommended. If you start the install-tool you can do a system check and get information about configuration which might need optimization.
Second: avoid development mode and use production mode.
the execution is faster, but you will loose the option to debug.
debugging always costs more time and more memory to prepare all that information. maybe 240 seconds are not enough and you even need more memory.
The field tx_fed_page_controller_action_sub comes from an extension it is not part of the core. Most likely you have flux and fluidpages installed in your system.
Try to deactivate those extensions and proceed without them. Reintegrate them later if you still need them. A timeout often means that there is some kind of recursion going on. From my experience with flux it is possible that a content element has itself set as its own flux_parent and therefore creates an infinite rendering loop that will cause a fatal after the max_execution_time.
So, in your case I'd try to find the record that is causing this (seems to be a page record) and/or the code that initiates the Query. You do not need to debug in Doctrine itself :)
I'm writing an application that can be started either as a standard WinForms app or in unattended mode from the command-line. The application was built using the VS 2k5 standard WinForms template.
When the application is executed from the command-line, I want it to output information that can be captured by the script executing the application. When I do this directly from Console.WriteLine(), the output does not appear, although it can be captured by piping to a file.
On the other hand, I can force the application to pop up a second console by doing a P/Invoke on AllocConsole() from kernel32. This is not what I want, though. I want the output to appear in the same window the application was called from.
This is the salient code that allows me to pop up a console from the command line:
<STAThread()> Public Shared Sub Main()
If My.Application.CommandLineArgs.Count = 0 Then
Dim frm As New ISECMMParamUtilForm()
frm.ShowDialog()
Else
Try
ConsoleControl.AllocConsole()
Dim exMan As New UnattendedExecutionManager(ConvertArgs())
IsInConsoleMode = True
OutputMessage("Application started.")
If Not exMan.SetSettings() Then
OutputMessage("Execution failed.")
End If
Catch ex As Exception
Console.WriteLine(ex.ToString())
Finally
ConsoleControl.FreeConsole()
End Try
End If
End Sub
Public Shared Sub OutputMessage(ByVal msg As String, Optional ByVal isError As Boolean = False)
Trace.WriteLine(msg)
If IsInConsoleMode Then
Console.WriteLine(msg)
End If
If isError Then
EventLog.WriteEntry("ISE CMM Param Util", msg, EventLogEntryType.Error)
Else
EventLog.WriteEntry("ISE CMM Param Util", msg, EventLogEntryType.Information)
End If
End Sub
Raymond Chen recently posted (a month after the question was posted here on SO) a short article about this:
How do I write a program that can be run either as a console or a GUI application?
You can't, but you can try to fake it.
Each PE application contains a field
in its header that specifies which
subsystem it was designed to run
under. You can say
IMAGE_SUBSYSTEM_WINDOWS_GUI to mark
yourself as a Windows GUI application,
or you can say
IMAGE_SUBSYSTEM_WINDOWS_CUI to say
that you are a console application. If
you are GUI application, then the
program will run without a console.
The subsystem determines how the
kernel prepares the execution
environment for the program. If the
program is marked as running in the
console subsystem, then the kernel
will connect the program's console to
the console of its parent, creating a
new console if the parent doesn't have
a console. (This is an incomplete
description, but the details aren't
relevant to the discussion.) On the
other hand, if the program is marked
as running as a GUI application, then
the kernel will run the program
without any console at all.
In that article he points to another by Junfeng Zhang that discusses how a couple of programs (Visual Studio and ildasm) implement this behavior:
How to make an application as both GUI and Console application?
In VisualStudio case, there are actually two binaries: devenv.com and devenv.exe. Devenv.com is a Console app. Devenv.exe is a GUI app. When you type devenv, because of the Win32 probing rule, devenv.com is executed. If there is no input, devenv.com launches devenv.exe, and exits itself. If there are inputs, devenv.com handles them as normal Console app.
In ildasm case, there is only one binary: ildasm.exe. It is first compiled as a GUI application. Later editbin.exe is used to mark it as console subsystem. In its main method it determines if it needs to be run as console mode or GUI mode. If need to run as GUI mode, it relaunches itself as a GUI app.
In the comments to Raymond Chen's article, laonianren has this to add to Junfeng Zhang's brief description of how Visual Studio works:
devenv.com is a general purpose console-mode stub application. When it runs it creates three pipes to redirect the console's stdin, stdout and stderr. It then finds its own name (usually devenv.com), replaces the ".com" with ".exe" and launches the new app (i.e. devenv.exe) using the read end of the stdin pipe and the write ends of the stdout and stderr pipes as the standard handles. Then it just sits and waits for devenv.exe to exit and copies data between the console and the pipes.
Thus even though devenv.exe is a gui app it can read and write the "parent" console using its standard handles.
And you could use devenv.com yourself for myapp.exe by renaming it to myapp.com. But you can't in practise because it belongs to MS.
Update 1:
As said in Michael Burr answer, Raymond Chen recently posted a short article about this. I am happy to see that my guess was not totally wrong.
Update 0:
Disclaimer: This "answer" is mostly speculation. I post it only because enough time has passed to establish that not many people have the answer to what look like a fundamental question.
I think that the "decision" if the application is gui or console is made at compile time and not at runtime. So if you compile your application as gui application, even if you don't display the gui, its still a gui application and doesn't have console. If you choose to compile it as console application then at minimum you will have a console windows flashing before moving to gui "mode". And I don't know if it is possible in managed code.
The problem is fundamental, I think, Because a console application has to take "control" of the calling console application. And it has to do so before the code of the child application is running.
If you want to check if your app is started from the command line in .NET, you can use Console.GetCursorPosition().
The reason that this works is that when you start it from the command line, the cursor moves away from the initial point ((0, 0)) because you typed something in the terminal (the name of the app).
You can do this with an equality check (code in C#):
class Program
{
public static void Main
{
if (Console.GetCursorPosition() == (0, 0))
{
//something GUI
}
else
{
//something not GUI
}
}
}
Note: You must set the output type to Console Application as other output types will make Console.GetCursorPosition() throw an exception.
