Property loader and translator

Solved!
Go to solution

Hi all,

I'm using a translator to convert xlsx to seq format. And it's working perfectly.

But I'm trying to use Property loader feature. When I launch the tool, I get an error( see below the call stack)

The property loader calls "CanTranslate" function of my translator (ExcelTranslator.dll) by passing argument file name : "C:\Program Files (x86)\National Instruments\TestStand 2019\Components\PropertyLoader\DocumentFormat.OpenXml.dll"

My translator returns False because it can't translate this file.

So the property loader generates an exception

So, do I have to modify my translator, or is it a bug in TS?

Thanks for your help

 

 

An exception occurred inside the call to .NET member 'LaunchImportExportTool':
System.Runtime.InteropServices.COMException (0xFFFFBD34): An error occurred attempting to translate the file 'C:\Program Files (x86)\National Instruments\TestStand 2019\Components\PropertyLoader\DocumentFormat.OpenXml.dll' to a TestStand Sequence File.

The 'CanTranslate' callback in 'C:\Users\Public\Documents\National Instruments\TestStand 2019 (32-bit)\Components\Translators\ExcelTranslator.dll' returned the following error:
This file's format is not supported or you don't specify a correct format.

Hi, 

Can you post your implementation for "CanTranslate" API from ytour translator plugin?

 

If your implementation looks something like this,

try {
    *translationIndex = 0;
     return 1;
}
catch(...)
try to change it to check for the specific extension that you support. So something like:
try {
    if (std::string(extension) == std::string("xlsx ")) {
        *translationIndex = 0;
        return  1;
}
return 0;
}
catch(...)

 

Hope this helps, 

 

Regards,

Hi,

I 've found my mistake.

I returned an error as string description.

In fact, NI recommand not returning an error just 0 as status.

 

Thanks
