The code you have posted shows (almost certainly) undefined behaviour, because of the incorrect way you handle the variadic argument list in your MessageBoxPrintf function.

In the wchar_t* c = va_arg(v1, wchar_t*); line, you are 'assuming' a single wchar_t argument – but, in your main function, you are passing two int arguments. This may or not produce meaningful results; – in your case, it seems that the first int argument is correctly interpreted by the subsequent call to wsprintf but the second is somewhat "lost in translation" (manifesting the aforementioned undefined behaviour).

To correctly handle that variadic argument list, you need to extract it, then pass it unprocessed to the vswprintf function, which can then properly interpret that argument list:

looks like you trashed something (driver or cuda runtime) and you are not able to call any function related to cuda.

in my humble experience, I usually get these errors when my kernels runs for too long on a Windows machine and the Windows Display Driver Manager reset my GPU while i'm running the kernel.

Maybe you are experiencing some similiar issues on linux.

To fix this, have you tried to reset your GPU using the following bash command line ?

You can do it in C# alone without VB.NET library

To quote from cppreference, (emphasis mine):

[allocate] ... allocates n * sizeof(T) bytes of uninitialized storage

In other words, there are no valid std::string objects there yet and trying to use them (even as the target of a copy) invokes undefined behaviour (I got a segfault).

To fix this, use placement new to construct the needed std::string objects immediately after calling allocate:

For security, the driver refuses to send these types of packets by default.

Of course, since you have the source code to the driver, you are free to modify this restriction however you like — it's your driver. You can add a line to specifically allow the 0x88A4 EtherType, or delete the entire if-statement to allow all EtherTypes. You can require the usermode process to be running as Administrator if it wants to send "suspicious" network frames.

A bit more detail on the security angle. If you allow untrusted users/programs to place arbitrary data onto the network, that may compromise or weaken network security. This is why the sample driver (and Windows in general) does not allow arbitrary programs to put arbitrary data on the network.

For example, a malicious program that has unrestricted access to the Ethernet layer can advertise a malicious DHCP server that points clients to a malicious DNS server, conduct ARP poisoning attacks on your switch, DoS a switch (with, for example, 802.3x PAUSE frames, or with LLDPDUs that undermine the QoS policy), or circumvent any firewall policies you might have.

These potential attacks aren't necessarily a deal-breaker: consider that this is roughly the equivalent of allowing someone to plug an arbitrary unmanaged device into an Ethernet jack on your network. If your network already has measures in place to defend against hostile Ethernet endpoints, then removing restrictions from the sample driver not making things much worse. Alternatively, if you have some level of trust for all the users & code on the PCs that will run your driver, then modifying the driver won't matter. Or if your threat model already assumes the network is hostile and unreliable, then removing these restrictions will only help fulfill your threat model's expectations. ;)

1. Since JMeter 3.1 you should be using JDR223 Test Elements and Groovy language for scripting

2. Groovy provides Find operator which looks like =~

3. Assuming above 2 points you can refactor your "code" to this one-liner:

Character arrays must be null-terminated to count as C strings. After the for loop, add text[rcvd] = '\0'; Also, your rcvd is fixed at 64. It needs to be one less than the array size for the null terminator to fit.

I think I see your problem, but I can't test it.

dtostrf returns a char * pointer to the string you want to print here's the docs

It looks like that function is being called and assigning that string to the temp variable which is a String type (idk your experience, but working with text in Arduino can be very confusing check out this thread ).

Try changing temp1 to be a char * like this:

Version 0.8.0 of the windows-rs crate switched to using impl Trait, making both the signatures easier to read, as well as decluttering the error diagnostics.

Given the code in the question, the error message now reads:
