Toolbox Integration Issue

Good day, I'm developing some code that uses this toolbox but have hit a bit of a wall.

For some context, I'm using VS2022 and have created some basic C++ code. I've added the proper header and DLL's. My program is able to compile and run but I get this error.

" Unhandled exception at 0x629E5391 (testo330Base.dll) in TestoIntegrationV3.exe: 0xC0000005: Access violation reading location 0x03BC19D9."

Below you'll find the code I've written:

int main()
{
void* hTesto330; // Pointer to a device handle
int i;

int num = Testo330GetNumberOfUsbDevices(); 

if (num > 0) {
    printf("We found %d devices", num);;  // Print the number of found devices
}
else {
    printf("No devices were found \n");  // Print a message if no devices are found
    return 0;                 // Exit the program
}

// Iterate through each detected device and print its serial number
for (i = 0; i < num; i++) {
    printf("device%d SN = %d\n", i, Testo330GetUsbSerialNumber(i));
}

// Open a Testo 330 device
hTesto330 = Testo330Open(0, 1, 0);

if (hTesto330 == 0) {
    printf("Error when opening device\n");  // Print an error message if device opening fails
    return 0;                        
}
// Close the Testo 330 device
Testo330Close(hTesto330);
printf("Close Devices \n");

return 0;

}

I'd appreciate any guidance or advice on the best way to address this issue.

Hello and thanks for reaching out, some questions without any further analysis of your code for the moment:

  • did you install the USB driver?
  • did you compile for 32 bits?
  • does the sample/online reader run?
  • does the log state anything?

Kind regards from Black Forest

It looks like you're using a testo 340, but the next log message that connection is established is missing. Weird. This requires further analysis and dialog.

Can you please reach out to us via helpdesk-Instrumentation the_usual_email_address_sign testo.de by including a link to this issue?

Sounds good.

I've just sent an email, but it seemed to bounce back. To confirm, the email address is [removed]?

I'm very sorry, I forgot to include a minus between the two words (of which I wasn't aware until yesterday as well)

Hey,
The request was sent on August 18 and I've gotten a ticket #. I'll forward you that information via email.

There indeed was a problem when calling that method for testo 340 and testo 330 (2004). It's fixed with release 1.5.2 via a21e20c . Thanks for your patience.
