running vssadmin from a program - c++

I'm trying to run the following command from a c++ program:
system("vssadmin list writers > tmp.txt ");
I'm getting this output:
"vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool (C) Copyright 2001-2005 Microsoft Corp.
Error: A Volume Shadow Copy Service component encountered an unexpected error. Check the Application event log for more information.
in the event log there are 2 errors: 22 and 8193.
if I run it directly from the command line it works fine.
Thanks.

The problem was that I was running a 32 bit application on a 64 bit machine thus windows was redirecting the app to the wrong vssadmin.

PlatformIO cannot open ftdi device (Arduino with esp32)

I am new to Arduino and using the esp32 and I am using PlatformIO to command my project in C++ through VSCode. I just downloaded my project folder and opened it in PlatformIO and attempted to run the existing code (over 1000 lines) which is meant to command an exoskeleton. When I run the program, however, I get error messages, as follows:
Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description '', serial '' at bus location ''
Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6014, description '', serial '' at bus location ''
I feel like I am missing something very basic, but everything I search for gives me very advanced problems, and I am hoping someone could dumb this down for me.
Any help is appreciated, thank you.
By the way, I am actually using Mac, and the output when I enter the ls -ls /dev/tty.usbserial-1410 is:
0 crw-rw-rw- 1 root wheel 18, 2 7 Dec 14:13 /dev/tty.usbserial-1410
You may used a different type of esp32 module (there're lots of variants in the market) from the original design. You have 2 options,
If the software works and you don't want to modify it, then try to find the same type of esp32 module specified by design.
Find out vid/pid from your current esp32 module and update software to connect. Refer to below procedure.
The procedures to update usb serial binding,
Run lsusb to find out vid/pid
lsusb commands
update the existing rule specified with vid 0403 and pid 6010 to your current vid/pid, usually the rule file is under /etc/udev/rules.d/.
Run sudo udevadm control --reload-rules to activate.

Openocd Error: invalid command name "dap" - can't connect Blue Pill via ST-Link/V2

I'm using a Blue Pill board (STM32F103CB with 128kB of flash according to st-info --probe) via a clone ST-Link/V2 like this one. I've also tested using a genuine ST-Link/V2 like this one. I get the same result, described below, with both programmers.
My system is Linux (Debian LXDE) and I've installed OpenOCD from Liviu Ionescu's releases here.
My OpenOCD installation is working. As well as the Blue Pill I have a ST-Nucleo-F103RB board, and I can connect to it using OpenOCD. The command
openocd -f board/st_nucleo_f103rb.cfg
using the standard .cfg file that ships with OpenOCD gives

But I still haven't managed to connect to my Blue Pill using the ST-Link/V2 programmers. I've read everything I can find, including relevant sections of https://elinux.org/Category:OpenOCD and as much as I can personally digest of http://openocd.org/doc/. The following is where I've got to.
The .cfg file stm32f103c8_blue_pill.cfg doesn't work for me. It produces the output described below.
Based on what I've read I've prepared my own .cfg file at ../board/stm32f103.cfg. It says:
source [find interface/stlink.cfg]
transport select hla_swd
source [find target/stm32f1x.cfg]
#source [find board/stm32f103c8_blue_pill.cfg]
#reset_config srst_only
#reset_config none separate
Sources I've read suggest this should work, but it doesn't. Using my .cfg described above, it I can use either target/stm32f1x.cfg or board/stm32f103c7_blue_pill.cfg, and I still get the same output as described below. (In the case of both of those .cfg files I'm using the standard files, as shipped with OpenOCD.) I've tested with both of the reset_config variants shown above, and with neither. None of the combinations works.
The file interface/stlink.cfg that I'm using is modified. I've changed it to state the correct device_desc "ST-LINK/V2" and the correct vid_pid 0x0483 0x3748. (Both confirmed using lsusb.) So, ignoring commented lines, stlink.cfg reads
interface hla
hla_layout stlink
hla_device_desc "ST-LINK/V2"
hla_vid_pid 0x0483 0x3748
I've experimented with including the hla_serial of the programmer. Interestingly, lsusb can't find the full serial number. st-info --probe finds the serial number, but gives a slightly different number from the STLinkUpgrade firmware application. I've tried using both serial numbers. No difference.
Here's the command I give to OpenOCD:
openocd -s ~/stm32/openocd/scripts -f board/stm32f103.cfg
Notice that I have to set the path using -s for this command. With the ST-Nucleo-F103RB board, I don't have to do this. With the stm32f103.cfg file, however, if I don't set the path I get:
Error: Can't find board/stm32f103.cfg
in procedure 'script'
If I use the full command shown above, with -s to set the path, I get:

Here's the offending line 47 of stm32f1x.cfg:
dap create $_CHIPNAME.dap -chain-position $_CHIPNAME.cpu
I've searched for items on Stackoverflow/ similar about Error: invalid command name "dap". Using the OpenOCD documentation I understand that the dap create command exists, and roughly what it does. The most similar reported error I've found documented is at https://elinux.org/OpenOCD_Troubleshooting:_Invalid_Command_Name_JTAG, and the solution suggested there doesn't seem to be applicable because I'm not invoking interface/stlink.cfg from the command line.
I can't see what I'm doing wrong, and I'm now completely stuck. If someone can give me a steer I'd be really grateful. Sorry it's such a long post.
I just encountered this problem too. Officially there are no binaries provided, only source code. But there are two sites which release binaries was recommended by OpenOCD official:
1. Maintained by Freddie Chopin.
2. Maintained by Liviu Ionescu in Github.
I tried the latest version(OpenOCD 0.10.0 commit date: 2017-01-22 20:31:28 build date: 2017-01-23) released from Freddie Chopin's site, and I encountered this Error: invalid command name "dap" problem. But all *.cfg files I referenced had ran normally in my another computer with another OpenOCD binary(although I forgot where did I download that binary).
Not sure what went wrong, so I turned to the latest version(gnu-mcu-eclipse-openocd-0.10.0-11-20190118-1134-win64.zip) released by GNU MCU Eclipse(maintained by Liviu Ionescu), the error was gone, problem solved.
PS: I'm not saying there is a bug in Freddie Chopin's build, but if someone encountered this problem, maybe you can solve it by trying the version which is currently under actively maintained.
Agree with Wulfric, using standard install for OpenOCD
sudo apt install openocd
gave the "dap" error.
However the github version openocd-xpack worked correctly.

vtkXOpenGLRenderWindow error in a terminal in VNC

I run a vnc server on my workstation and connect with another computer. Both of the server and client are running Debian Jessie:
$ uname -a
Linux debian-VAIO 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2+deb8u2 (2016-06-25) x86_64 GNU/Linux
Xfce is installed for the vnc server and xstartup is:
$ cat ~/.vnc/xstartup
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
exec startxfce4
In the ~/.bashrc, I have added the lines below:
export LIBGL_ALWAYS_INDIRECT=y
export LD_PRELOAD='/usr/lib/x86_64-linux-gnu/libstdc++.so.6'
Currently, when I ssh to the server with ssh -X, the $DISPLAY is localhost:10.0, and the vtk related command will launch an X window. However, if a vnc server is launched in the ssh terminal, logging into xfce and opening a terminal in it, the $DISPLAY is :1.0 and vtk fails to launch an X window, with the following message:
Error: In /home/orobix/Desktop/vmtk-build/VTK/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 394

vtkXOpenGLRenderWindow (0x2c30f10): GLX not found. Aborting.
I think it might be relate to the missed config of X server in xstartup of vnc server. But I don't know how to do it. Could anyone help me debug it? Any further information will be provided if needed. Thanks!
20160823 Update
I accepted the suggestion of VirtualGL + TurboVNC and installed the two components. A simple config using vglserver_config was done according to http://www.virtualgl.org/vgldoc/2_1_1/#hd009001 part 6.1. Then I made vncserver of TurboVNC to run xfce with xstartup.turbovnc:
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
OS=`uname -s`
exec startxfce4
On the client, I use vncviewer of TurboVNC to connect the server. The desktop looks quite different from that in a default vncserver. Then I tried
/opt/VirtualGL/bin/vglrun vmtkimageviewer -ifile image_volume_voi.vti
in which the vmtkimageviewer should open up a window, but finally it gives out an error:
Executing vmtkimageviewer ...
X Error of failed request: GLXBadContext
Major opcode of failed request: 156 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 17
Current serial number in output stream: 16
And unfortunately, I find that with ssh -X, I cannot launch the X window as I did before, although $DISPLAY is still localhost:10.0. The output is:
Executing vmtkimageviewer ...
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 156 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 37
Current serial number in output stream: 38
But I think I am closer to the fact, as it looks like VirtualGL works(?). What to do for the next?
Plain and simple the X server variant that's being used by Xrdp (either Xvnc or Xvfb) simply doesn't support OpenGL / GLX and thus programs that need OpenGL will not work in that configuration.
Fallback to Mesa swrast or llvmpipe is possible though: http://www.mesa3d.org/llvmpipe.html
Finally, I got everything done. VirtualGL only is enough for my purpose. Just install and config as the section 6.2 & 6.3 in its user's guide. Use the default vncserver and vncviewer as usual, TurboVNC is not needed. Use vglrun when you need an OpenGL support. One modification is that I should remove export LIBGL_ALWAYS_INDIRECT=y in my .bashrc.
It runs fluent in my case. #datenwolf: Thank you again!

Selenium Command line server for the IEDriverServer has stopped working App Crash error

I have a Selenium Python automated regression test script running on our 64bit Server on IE11, Windows Server 2008. Everytime when the test gets about half way through an error dialog appears and the test stops. The error is:

Anyone know why the IEDriverServer is crashing?
On our 32bit server the tests runs ok all the way to the end. Over 230 test cases. But on our 64bit server the App Crash error appears half way through.
I have set the registry DWORD value:
For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.
IEDriverServer.exe is also in my Path
And also i notice in Task Manager iexplore.exe it's memory usage is 2.95GB
Is this normal? The memory seems really high.
Does Selenium need over 2.95GB of memory to run the tests in IE11?
Thanks, Riaz
If you are using 32bit IEDriverServer.exe for 64Bit OS then you switch over to 64 Bit IEDriverServer.exe because there could be reason of mismatch 32bit to 64 bit combination behind crashing of IE driver, and now if using 64 bit IEdriverserver.exe and you are having slow typing issue then to overcome this issue for 64bit exe over IE 11 browser Follow these steps:-
Internet Options -> Security -> Check "Enable Protected Mode" for all zone
Go to Advanced -> Security -> Check "Enable Enhanced Protected Mode"
this works for me. Cheers!

error: initial process state wasn't stopped: exited

I'm having a problem debugging a command line program on OS X. I've used this same source file with the same g++ command line hundreds of times to test things with the Crypto++ library.
Under GDB, I get the following after loading the EXE:
$ gdb ./cryptopp-test.exe
...
(gdb) r
Starting program: /Users/jwalton/cryptopp-test.exe
Unable to find Mach task port for process-id 42811: (os/kern) failure (0x5).
Under LLDB, I get the following:
$ lldb ./cryptopp-test.exe
Current executable set to './cryptopp-test.exe' (x86_64).
(lldb) r
error: initial process state wasn't stopped: exited
I've recompiled the program a few times, and I can't get it to run under a debugger. I'm getting a segfault when trying to run outside the debugger too, so that may be a symptom here also.
OS X is 10.8.5, and Xcode is 5.1.1 (5B1008). Everything is fully patched. The only thing to change recently is signing up for a developer account, which is broken thanks to Apple's DRM crap. I can't seem to get any of it to work with Xcode or the command line even though Roots and Certificates are in my Keychain. But this program does not use code signing.
What is causing the initial process state wasn't stopped: exited error, and how do I fix it?
The errors that you have received are usually a direct correlation of a codesigning issue, not with your executable, but with gdb and lldb themselves.
You have a couple of options:
Launch gdb or lldb as sudo (which ignores the codesign req to run executables)
Create a codesigning certificate for gdb or lldb in Keychain.app
Obviously the first option is quickest, but probably should be avoided as it opens up the possibility of bad things happening with elevated permissions.
With option #2 you can likely get gdb or lldb properly working by doing this:
Launch /Applications/Utilities/Keychain Access.app
Select the Keychain Access -> Certificate Assistant -> Create a Certificate...
Choose a name for the new certificate (for example lldb-cert or gdb-cert)
Set Identity Type to Self Signed Root
Set Certificate Type to Code Signing
Select the Let me override defaults option
Continue until the "Specify a Location For The Certificate" screen appears
Set Keychain to System and Continue
In the view showing your certificates, double-click on the one just created and then set "When using this certificate" to "Always Trust"
In Terminal:
codesign -f -s "gdb-cert" /path/to/gdb (or) "lldb-cert" /path/to/lldb
You might have to restart for this to effectively take hold.
There are more concise instructions here for gdb and here for lldb on the codesigning process.
